Fuel battery is a direct result will be stored in the fuel and oxidizer for chemical energy into electrical power devices efficient generation.

According to the different types of fuel battery electrolytes can be divided into:

(1) Fuel batteries at low temperature, such as fuel battery solid polymer electrolyte (PEMFC) and alkaline fuel battery (AFC);

(2) Phosphate acid fuel battery (PAFC);

(3) Fuel battery molten carbonates (MCFC);

(4) Solid oxide fuel battery (SOFC) and so on.

SOFC is the second PAFC, MCFC greater efficiency of energy conversion after the third generation system, fuel battery, is considered the most effective systems and universal power generation, especially as decentralized power plants , scientists from various countries are being attracted great interest. It is the fuel and oxidant gases by an ion-conductive ceramics, and generation of strong electric power and energy for the state apparatuses of conversion, it is also known as fuel batteries ceramic.

Include SOFC electrolyte and two electrodes. In the cathode, the air of oxygen dissociation into oxygen ions, two electrodes through the solid electrolyte membrane between migration to the anode / electrolyte interface of the reaction of fuel. Outside the circuit, the anode to the cathode of the electron flow generated DC. SOFC solid electrolyte is the most central parts. Her performance is not only a direct impact on the work of the VGP-BPS10 battery temperature and the efficiency of power conversion, but also determines the required matching electrode material and the corresponding choice of preparation technology. Discovered so far may be used for SOFC oxygen ion conductor mainly fluorite phase structure of ZrO2-based, CeO2-based, Bi2O3-based materials and the perovskite-type structure LaGaO3 based materials.

In addition to the overall merits of the SOFC fuel battery also has the following characteristics: Adaptability of the fuel can be a variety of fuels, including the case of carbon-based fuels to run, does not require the the use of noble metal catalyst, the use of all semiconductor components state, there is no right, leakage corrosion management issues; blocks of solid, flexible, and therefore the size and the ‘install location. These characteristics make fuel efficiency for electricity production at the time the cycle has the potential of more than 60%, while the effectiveness of the entire system, up to 85%, 1MW SOFC / M3 power density, the design of the block may be as high as for 3MW / m 3. In fact, SOFCs can be used to produce energy, thermal recycling, transportation, aerospace and many other areas of space known as the 21st century green energy.

SOFC research and development of the future based on the following aspects:

1. New electrode materials and other components of the VGP-BPS13 battery development.

Modification of other SOFC components, allowing the system to optimize the structure to meet the average fuel battery operation temperature, the development of the temperature conditions in a given activity in the same time, they met the electrolyte performance is the electrode material, improve the structure of micro-electrodes. A nano-electrode is a possible route. It has small particles, increasing the three-phase industry (catalytic center) in length and electrode / contact area of the electrolyte, which significantly reduces the interface resistance, may also reduce the thickness of ‘electrode, so that gas is more easily spread in the three-phase interface, decreases due to concentration polarization electrode caused by the reduced efficiency of the battery.

2. Head Proton and Proton – Development of ion mixed conductive electrolyte.

For a proton conductor as electrolyte, the water produced in the oxidizer side, so there will be no driver of oxygen ions as electrolyte, as, after the reaction of the fuel batteries needed to remove water fuel. When using methane gas and other hydrocarbons, only the pyrolysis of these fuels can be considered as the fuel hydrogen proton conducting fuel batteries, while the remaining part of the restructuring could serve as a useful product is retained by the reaction of batteries such as ethane, after their return – availability of ethylene. Some electrochemical reaction must use the proton conductive material. Such as emissions of H2S industry to cope with this fuel VGP-BPS11 battery can produce electricity at the same time, be a useful byproduct of S2.

3. Study of the mechanism of proton conduction and to develop sufficiently in the conductivity of proton-conducting temperature.

This is a promising line of research. It must be said – proton mixed conductor of ions is a solid electrolyte, to find the material itself is a new challenge, which, for deepening our understanding of new SOFC has a special meaning.

4. New concepts and methods.

The recent emergence of the single battery fuel chamber is a new concept. Despite its many shortcomings, but it is a research direction is worthwhile. His main interest lies right to our future design of the battery to provide useful inspiration. For the structure of the electrode material, the majority of electrodes traditional asymmetric electrodes, said cathode and anode materials used in the individual. If you are using symmetric electrodes, the battery performance will be? It deserves to be studied. For methods of VGP-BPL11 battery preparation, the method currently used mostly expensive, finished product rate is low. Research and development of soft chemical preparation routes, the introduction of light conditions, methods of physical preparation is required to have a strong competitive advantage.

Sony hopes that the new TV-compatible 3 – D can be achieved television half of sales in the last three years he has sought a detailed support their sagging business.

Hiroshi Yoshioka, Sony’s Executive Vice President and Head of Consumer Products and equipment of the group also said the company is in talks with several car manufacturers to enter the huge market, but filled with lithium – ion car. He has not the name of the car manufacturer. Much of the investment of 100 million U.S. dollars in VGP-BPS8 battery technology in the coming years will be used in car batteries, he added, Sony has also increased in this area of employees.

Sony 3 – D-TV and video-game demonstration in October.

Details contributing to the formation of an overall strategy on Thursday, offered last week in Japan, Sony are planning to rely heavily on technology, and 3 – D-line content to an operating margin of 5% to achieve the fiscal year 2013 to year ending in March.

Sony has announced that sales have more than 100 trillion yen (approx. $ 11.4 billion), three-dimensional aspects of products such as televisions, DVD players and game consoles objectives in this work. The company plans to introduce a 3 – D-compatible TV for the next year, Mr. Yoshioka said that today the nature of the collection make 30-50 percent of TV sales at the end of 2013. This VGP-BPS8A technology can help you choose the audience to see, in the current model, two-or three-dimensional aspects of the television special glasses.

Sales depend on the existing 3 – D content, Mr. Yoshioka added that he saw great potential in video games. Sony says that these models 3 – D-TV will be priced at a premium, but there are the glasses is the most expensive Sony, but as the actual production of television.

In the battery, Sony plans to play for the safety of the product. Mr. Yoshioka, batteries, the company has developed because the battery has in the past Sony to create a safe product. Sony and many other recent cases, to a battery of consumer products such as laptops subjected caught fire.

Sony believes that the battery market is enormous and the prospects that it would make, even if the current behind other providers. “We have plenty of space, said:” Yoshioka. Sony said that there are currently around 2,000 employees working in the field of batteries, but plans to increase this figure.

Vice President Howard Stringer, Sony shaking in society by deficiencies in the content and software companies, high costs for the troubled production. It expects an operating loss of 60 billion yen (approximately USD 684 million) this fiscal year, but Mr. Stringer said the company’s efforts to balance, by reducing costs and other activities.

Used in fast voltage control load to avoid overloading the internal methods of detection, most common are fixed, temperature control and more control, or mixed-use three ways.

1. Constant voltage control

When the battery voltage is detected at a voltage almost bit set to stop the charge. This approach is the easiest way to know that as the characteristics of the Laptop battery in the battery voltage curve upward, you can detect the voltage to the nearest filling when the quasi-saturation space, different styles of recharge battery when the voltage is almost saturated like the old and new batteries are not the same characteristics, using this method can not put more ideal tension. Although this method is simple but also very dangerous, said earlier, temperature is higher than the battery voltage and reduce current load will be raising the temperature of the battery, so it may have been perceived the battery voltage has not yet reached saturation, but the quasi-set position, and the battery charging voltage does not increase after saturation began lower and thus the consequences of overloading is very serious, if it comes with an internal short-circuit the battery charger is not able to protect the circuit, once the current consequences are too dangerous would be unthinkable, so this way during charging, the user should take note.

2. The temperature rise control

Battery charge generated during the oxygen saturation in the cathode of cadmium oxide and heat of reaction, the battery temperature begins to increase rapidly using this phenomenon to detect when the temperature reaches a certain extent, both the end of the load. In the same amount of charge under the current load plus the increase of the higher temperature, so if the load current is too large to meet the set temperature of the 40Y6797 battery may not have been saturated, but the current if it is too small, then oxidation to absorb quickly the temperature does not increase significantly, the charge movement was to continue but can not terminate. In addition, this approach will be affected by ambient temperature and can determine the battery temperature is in the self-product of chemical heat, or the environment caused by the heat of denial of justice, so this method in a high temperature environment will be charged absence of a cold is too cold.

3. Control

Charging the battery voltage increases as capacity increases load when the load capacity to reach saturation, the voltage rises to the point, and instead began to decline slowly. Enjoy this voltage drop characteristics can be used to control the voltage charge termination shall be when the drop was not more demanding, typically 1.2V nickel-cadmium batteries will be 20mV of its decline is almost complete (the actual size of data May refer to the VGP-BPS8 battery) in the process of charging can be clearly observed count Out. curve of charging voltage of battery is charging current and temperature effects in the same load capacity, the current is higher or lower temperature, the voltage increases the margin is low, the decline is also more obvious. Current is smaller, or the higher the temperature, the voltage increased the smallest rate of decline is relatively flat is not easy to distinguish. Therefore, control methods applied fairly rapid charging years, and to avoid the influence of temperature to detect the failure, usually with the control of the temperature increase in the use, in order to avoid overcharging.

Nickel-cadmium batteries, they are saved by the use of long-lost, or have already dusk, and the first few minutes before recharging will take place and the tension is not only the filling of the case will also down then up the cases involving the termination of a miscarriage of justice charges. Control method is a better method of controlling the characteristics of different batteries can still use the features of the batteries fully charged issues, the comparison does not need to worry about voltage control or adjustment the temperature function and damage the battery.

Currently, computer advanced many controlled chargers are the use of such control, and the price is expensive than ordinary chargers, and some of the reputation of the name even if, in fact its control programs and the load circuit is not their design, have tended to have misjudged the situation, rather than the battery charge enough to cook an egg, which is not even enough to strike are not yet sufficient to determine the battery was full, so better a charger in addition to increasing the temperature beyond the control of, and then under the non-recurring charge, voltage and current size evolution, calculate the load capacity and to determine if the VGP-BPS9 battery has really reached the saturation point.

The three methods are fast charging method, after loading, depending on the characteristics of the battery self-discharge, usually on the battery to continue to impose a small surcharge to offset the current battery leakage underway, and the speedy and can not be be able to achieve one hundred percent guarantee that is fully charged, charging a small current to continue to fill gaps in just to fill the building. usually about the size of the C / 20 ~ C/40 additional current between the general use of the fast charge mode the charger to recharge the battery to terminate after all Kangjing OK to enter what is called the slow charge mode Indeed, that is, as a small current to continue to supplement battery charging. In this mode, the small current is almost not let the battery produces little heat, not letting the tension is much change for shippers are almost always intended to complement the purposes of collecting and will not stop not automatically, but not yet as to the apple A1022 battery battery caused by overloading, but to avoid increasing the crystallization behavior of nickel, users always have the discretion to add time of pricing.

In comparison with other secondary batteries, lithium-ion batteries with excellent performance are widely used in mobile phones, laptops and other electronic products. The use of the process, noting what is important is perhaps our greatest concern. To this end, we must listen to the opinions of experts and suppliers.

Laptop Battery Conservation Strategy

Many people use laptops were used for piloting an external power supply, but such use would damage the battery or even unusable. The reason is connected to the area after the laptop battery will be automatically debited, which is actually equivalent to a daily part of the battery charge and discharge, thereby affecting the battery life. I often use the power of work when you remove the battery.

If the long-term use of external power, the use of 1 week (up to 1 month) should be a full charge and discharge, so that can repair the control system of the battery (register) Lane n ‘ was not in use, but may charge a nominal capacity of control and consistent fact throughout the charge and complete discharge to calibrate the battery chips. This is preferable to make the battery removed.

Founder of mobile technology products development, product engineers, Cao-ping said that after repeated load, the discharge capacity of lithium-ion batteries will decrease, the decrease of battery capacity in the degree is directly proportional the number of loading and unloading.

Newly built lithium-ion battery, only charge about 50% of capacity, the new laptop batteries as well. Used for the first time that I need to put the power to do, then an external power supply is fully charged, but the first charge preferably exceed 15 hours. Secondly, we had to wait three rechargeable battery is worn out, charging time to over 12 hours.

Many providers, such as the Founder of the laptop power supply circuits and the battery itself, are designed to load and unload circuit monitoring and protection, battery power will be monitored through the surveillance system , consumption below the value set, the device will issue a warning, then May be to charge the battery.

CAO Guo-Ping said that not long term use of batteries in stock before they must be charged or discharged battery to about 40%, then placed in 15 to 25 degrees Celsius dry preservation interval of 3 months to remove the checkmark from the battery to prevent battery discharge too bad. In addition, under normal circumstances, the battery is full, the system will automatically cut the load circuit, seeing the machine to move the eradication of brilliant. If the VGP-BPS8A battery-charging, the battery temperature will increase, so that excess energy, gas internal decomposition of the electrolyte, causing the battery internal pressure increases the risk of spontaneous ignition produce or rupture. Therefore, Founder Technology has been to recall the client, laptop battery must be charged on the original machine, to prohibit the use of third party shipper or other models of laptop charging, in order to avoid unnecessary risks.

Battery for joining the same direction that development is always environmentally friendly, safe, lightweight, and the same amount of space for greater storage capacity. On current trends, the laptop battery is still the main application of lithium-ion VGP-BPS8A battery, fuel cell is most likely to replace current lithium batteries, but the status of ongoing development, may also need several years of ‘efforts and solar cells on the more environmentally friendly, but because it is the output voltage and power are too small, such as application backlog will have to wait before the next breakthrough technology widely used.

Samsung Mobile-related person in charge, said: impact of the life of lithium is an important factor in the number of loading and unloading. Therefore, if the batteries used frequently, the time the battery will decrease quickly. In daily use by the process, pay attention to, without the battery when it would be better off, while minimizing the number of battery charge and discharge in order to ensure that long-term battery, a effective use. High current battery charge as long as does not exceed the rated voltage, the impact is minimal. Samsung quick charging technology is portable VGP-BPS8B battery as possible within the limits allowed by the growing tension, the pricing, if time is short compared to other brands of computers advantage of charging time is obvious. The depth of discharge is usually used when time does not use the battery is good, if not the depth of discharge will affect the frequency of battery life. If the short-term need to maintain 50% of electricity better.

Although the Li-ion battery memory effect is not obvious, but not always operate to food after the proposed charging, the battery is fully charged, after a laptop generally has a detection circuit automatically stops load, it is generally little impact. It should be noted when used frequently or not to charge and discharge the battery, once used, a full investigation, the lowest frequency of use, battery life longer. The direction of future development of the main battery is a high cohesive energy, high-capacity portable. Samsung is also developing a variety of concepts VGP-BPS9 battery products, particularly fuel cells developed quickly, hoping in the near future may be applied to laptops from Samsung to offer users a better experience and more practice.

To reduce the hardening of the battery to extend battery life, we must first improve the working conditions of electric bicycles. Reduction of body weight, getting rid of unnecessary decoration pieces, the appropriate speed limits, does not weigh very long when you do not use electric bikes to add to the burden is better able to recharge after each discharge and not under-voltage protection and to guard against VGP-BPS8B battery over-discharge protection for a minimum of 24 V rated voltage must be located at 21.5V ~ 22V, 36V nominal protection to a minimum voltage must be selected 32.5V ± 0 , 5 V for a nominal 48V to be located at 44V ~ 45V. The tension on the renewal of such a line capacity is only reduced by less than 2 km, but it may actually prolong the life of the battery. Every three months on a regular basis and not the professional maintenance of cells in repair and recovery in time. The method is simple, the economic cost is very low, but there is some difficulty in complying strictly. Thus, you can use specialized equipment for maintenance of desulfurization, these methods are:

1. The use of office equipment desulphurization fast

Desktop rapid desulfurization devices works is a high voltage, high pulse load current through the elimination of a negative amount of sulphide block wear. This method is fast, fast, get a temporary suppression of the effect of the treatment, but the high voltage high current can blow desulfurization may also reflect the active substances, including the elimination of lead sulfide in the positive plate to severe dehydration and softening problems, fatal damage to the VGP-BPS8A battery through the equipment in more than two sulfur base will be discarded after the battery. In addition, the current point for an addition to the professional maintenance of the basic fee of sulfur in 60 to 80 hours, up to six months, the life of the battery and is not the User substantial economic benefits. Currently, the battery on the market to maintain professional traders must understand the dangers of this approach. As a result, became the desulphurisation equipment discharge pulse, in effect, a fundamental principle has not changed is only the constant current in high voltage transients Hengda peak pressure, or will it damage the electrode active material, used friends of these products must be very clear on this point.

2. Options for desulfurization Chargers

In addition to battery charger sulfur is currently available in three works, one of which is similar to office equipment desulphurization fast mode of operation, using high voltage high current pulse load, blocking the desulfurization wear negative above indicated that this method of battery life would be a mortal wound, was refused by the market. The second is used fast pulse edge of the charge and discharge pulses, the use of peak instantaneous interfering with the collection process of vulcanization of the battery. The other is cyclical, with 10% to 20% over-charging method, to restore the battery to lead sulfate crystals. Both chargers can be added when the sulfur in the feed, but it will result in less load, or overload, but also ignored the procedure for discharge of the  VGP-BPS8 battery is the fact that most process drying, if the result is not satisfactory, the majority of users The charger is equipped with electric cars would leave after such a duplication of investment in desulphurization methods.

3. Use the online lead-acid battery extended life support

On the online extension of life support-type lead-acid batteries and battery in parallel, can be 24 hours to prevent and eliminate sulphides. This method is slower restoration, repair time is quite long, often more than 120 hours, but both charges discharge process is also capable of preventing and eliminating the healing, repair works. Because low voltage and low voltage, prolonged life support does not exert a strong impact on the battery plates which leads to dehydration and mitigation, which is a user input can be validated at the track maintenance , especially for the quality of the new battery can extend the battery life of 2 to 5 times, and entry may be accompanied by an electric motor, the next time to replace the battery, extending the life support can also continue to be used for users to save considerable economic costs. If a user once a year to replace the battery, a battery 280, the user 10, spent 2800 yuan should replace the battery on the conservative calculation, if you use extended life support twice the length of battery life of 10 years, can also save about half of the battery is charging.

To adopt this approach very significant. Firstly, the user has brought tangible economic benefits, reducing the user of trouble. Second, it enhances the reputation of the warehouse, provided that the conditions for expansion of production. Thirdly, to solve the battery electric vehicle warranty dealer is very hard to reduce complaints, improve credibility and increase the point advantage at the same time, in-store sales also increased to promote programs of commercial marketing. Fourthly, we can greatly reduce the demands of the VGP-BPS13/S battery manufacturer for the reasons. Fifth, improve the image of electric bikes, electric bikes to expand the overall market development. Sixth, improving battery usage, there are environmental.

1. INTRODUCTION

Battery electric vehicle is a key driver of production units in lead acid batteries, nickel-cadmium batteries, nickel-hydride batteries, metal, lithium batteries and fuel cells are more commonly used batteries because the high energy that large, light weight, good temperature characteristics, low pollution memory effect is not obvious characteristics such as nickel-metal hydride batteries used in electric vehicles are common. However, due to poor loading method, resulting in the life of the Laptop battery pack is well below the stipulated life. It’s much the battery is not bad but is filled with bad, good or bad for the battery charger can be seen a great impact on life expectancy. For this reason, this paper presents a three-stage program load control using smart charger design can actually improve the pricing efficiency and prolong battery life.

2. Control method developed

Methods of charge termination control are commonly used: a method of controlling timing, method of control voltage, the current method of control and integrated control laws.

Timing Control Act refers to the timing system to control the charging time, time has no value when they arrive on the Dell Inspiron E1705 battery to stop. Do not load. Commonly used in the law of voltage control, including the highest voltage (Vmax), the incremental negative voltage method (△ V), zero voltage increment method (0 △ V) commonly used in law to control temperature, including the method of maximum temperature (Tmax), method of filling temperature (△ T). Percentage change in temperature (T △ / △ t), the method at low temperature (Tmin). Integrated control method is the use of combined methods of controlling the above-mentioned in several control methods.

Compared with traditional fixed voltage and constant current charging method of three theories fees can greatly improve the efficiency of the battery. Three stages of indictment charging the first constant current and constant tension, the final adoption of floating Chong Chongdian. If the battery pack in deep discharge state of the former are still borne by the preload.

3. System hardware structure

3.1 Design comprehensive material

Subject to the nickel-metal hydride rechargeable VGP-BPS2C batteries, using the method of voltage and current feedback to achieve constant current, constant voltage goals, while the charge in the testing process and control parameters.

The program switching power supply maximum output of 2.4kW, AC input range of 1 76V-264V, charger circuit comprises essentially the main circuit and the circuit load auxiliary control of two parts, the whole process of operation of the circuit: 220V single phase power supply across the bridge.

Rectifier is filtered by the capacitor to move about 300V DC, after a composition by the four-bridge IGBT inverter with high frequency alternating current through the high frequency transformer coupled to the secondary side, and then through the rectifier D1 , rectifier D2 and finally by the inductor L 2 and capacitor C8 filtered to provide a stable DC. Following three tasks at each stage of the charging voltage and load current are different. Thus, as the charging process using the ATMEGA8 MCU control equipment, rechargeable batteries, charging SCM detect the load current, charging voltage, the battery temperature to prevent the circuit from overvoltage and overcurrent, the battery temperature is too high, you can also detect the battery voltage and current values to determine if the transition to the next stage of a fee. Now, every step of the SCM is given the value of the charging voltage or current value, and the corresponding sample obtained from the voltage and current through the UCC3895 phase-shifted PWM control chip to change the value to change the power tubes on time, to achieve at different stages of a stable output value of different purposes.

3.2 describes the circuit pressure maintenance

Main circuit charging circuit full bridge inverter. IGBT H-bridge with four components T1 T3 tube Q4 Q2, Ql and Q4 formed ahead of the bridge arm to achieve zero voltage turn on and off, Q2 and Q3 GAL composed Arm Bridge to zero-current turn on and off. Labor and Q2 of the inverse of the driving voltage, Q 3 and Q 4 of the control voltage is also the inverse, Q 1 and Q 2 and Q 3 and Q 4 to turn the switching dead time can be is in phase transfer controller UCC389S controlled by adjusting the mobile phase T4 ahead of the bridge arm to adjust the conduction time common to adjust the duty cycle to achieve the goal of changing the output hp F2024A battery power. Q2 and Q3 GAL consist of the theory of arms control and the bridge ahead of the same bridge arm.

In recent years, with electricity, coal, oil and not other sources of renewable energy most often in cases of urgency, energy is increasingly a bottleneck limiting the development of the international economy. The post-oil era, so that people will once again focus attention on development of new energy sources and use of this has to a certain extent, the promotion of the energy industry of the Laptop battery system. People will turn his attention to lithium-ion batteries, fuel cells, photovoltaics, wind energy battery research and development. Experts believe the battery industry in China in terms of improvements in technology or the structure of demand, has inaugurated a new era of development.

Fuel Cell

It is not easy to say love you

In today’s era of global energy crisis, the search for new energy sources as a substitute for fossil fuels is a priority. Because of its ease to get fuel for fuel cells, environmental protection and sustainable use of the advantages of the battery industry and has become the new subject, especially in the automotive industry in the promoting pollution-free fuel cell zero emissions, the parties concerned is given a high degree of recognition and evaluation. In recent years, Europe and the United States, Japan and other developed areas and the state has put a lot of fuel cell R & D strength, China from 50 years in the 20th century conduct fuel cell research, is now a key material in fuel cells, the key technological innovation has made many advances. Beijing Olympics 2008 on the use of green fleet of 20 self-developed fuel cell electric cars.

Experts predict that by 2013 the global market for fuel cells could reach 35 billion dollars. In 2006, the performance of fuel cells will be improved, its sales will also significantly increased. Fuel cells increasingly global, so many people in the industry that fuel cells will have a huge market space, will become a trend in the development of industry Dell Latitude D800 battery. However, there are different voices in there.

“Fuel cells can not say that the development of leadership, but not become a trend.” China Battery Industry Association, said the Secretary-General Wang Jingzhong. “Now, both foreign and domestic Cells fuel is still in development stage of a trial and do not form a mass, industrialized production. “Wang Jingzhong introduction, the reason why fuel cells are not an industrial production, mainly by two factors, one is subject to physical constraints, fuel cells require platinum as anthrax, and materials such costs very expensive. It is understood that the annual world production of platinum in 2006 to 200 tonnes in 2007 to 220 tons. Production Annual China only about 4 tons and imports about 40 tons, mainly used in the chemical industry and jewelry carved. “All electric vehicles to fuel cell 50.000 would require at least 1 ton of platinum, just this platinum scarce and expensive resources are involved, how to support affordable industry Fuel Cell Electric Vehicle to be? ” Chinese Academy of Engineering, YANG Yu-sheng also expressed the same opinion.

The second is a security risk. Wang Jingzhong that fuel cells are mainly used in the car, then install the bottle if the quality of fuel to cross the border if a collision does occur under high temperature and so on will have security implications.

This year, in May, Minister of Energy of the U.S. government, Obama has officially announced that the government stops its support for the research of fuel cells for electric vehicles and development. The electric vehicle fuel cell has been vigorously defended by the Bush administration as the “hydrogen economy” theory of magic “.” “In the substitution of the new technology of platinum catalyst has been no fundamental breakthrough in this problem before electric vehicles to fuel cell may not be big development. In addition, hydrogen is a secondary energy consumption of primary energy can be obtained, the total energy efficiency of fuel cells power conversion was not high. do basic research is the key. YANG Yu-sheng.

Solar energy, lithium-ion hp F4812A battery

Synchronization with developed countries

“Currently, the battery industry in China in research and development of new battery technologies and abroad at the same starting line, just to see who will be a bigger breakthrough.” Wang Jingzhong say with confidence: “Now, we focus primarily on lithium-ion batteries, solar panels in the development and research.”

According to Wang Jingzhong New China was founded, the battery industry in China is in a state of destitution, the battery is just over 3000 million Value of production less than millions of dollars in total workshop-type enterprises. While 60 years later, China became the first battery of the world-producing countries, production increased by 1,000 times, sales have increased by tens of thousands of times more, varieties of the battery New China was founded in the early dry and paste-type open-type lead-acid batteries as several hundred to our days. Mercure advanced without alkaline manganese batteries, valves sealed lead-acid batteries, lithium-ion battery, Ni-MH batteries, solar cells and other products has become China’s main industrial sony VGP-BPS5 battery products, technologies, equipment and product quality has been synchronized with developed countries, China cell industry has established a complete industrial production support and research, are moving toward a world power in the battery industry. As an energy industry news, an important component of the solar wind and other renewable energy sources, electric vehicles and other emerging sectors, the rise of China Battery Industry is a new cycle off and created a solid foundation on the market.

It is understood that, after years of development, new energy industry of China has made considerable progress, China has the production capacity of solar cells has reached 2900 megawatts in the first place in the world. The lithium-ion batteries because of its cycle of good performance, high safety factor advantages in electric cars has played an important role.

China Battery Industry Association, Jin-Liang Wang, Director of the Technical Committee also believes that the new battery technology affects the world science and technology and advanced development of high technology industry, one of the cell industry is the greatest development potential in the century, 21e, an industry of the future, with the rapid development of world science and technology, Battery industry in national economic development in China will play an increasingly important role. China is now the largest producer of batteries and larger battery consumption of the country, oil and other escalating energy crisis, people become more aware of protecting the environment, the battery industry is seeking new opportunities and challenges in the development and technological breakthroughs.

Advantage lies in its mobility specification, if it is 3 kg and above included in the income, or 1.5 kilograms under the ultra-portable notebooks, with the battery pack, they may come from an external power supply of further work is essential weapon mobile computing. Batteries in laptops are central, but the proper use of laptop batteries, but there are all sorts of stories, we have consulted in the design of laptops has extensive experience in research and development, combined with their own experience to show you briefly how to treat their own laptop batteries.

Firstly, kinds of popular practice that the use of electricity in the long hours, many users will remove the laptop battery that can extend battery life, in fact, do not remove too. For users who do not remove the battery must be careful not to frequent Plug Power, which is due to appear discreet power socket short supply will be generated in the battery charging and discharging process, and frequent charge-discharge operation will shorten the battery life, while for the battery on the user side, the best time to time (about a month), this will be the battery in his laptop and recharge so that the Laptop battery can maintain the best state, if the battery is idle for too long will lead to a reduced capacity.

Second, lithium-ion, the depletion of the battery is not necessary to conduct further charge that because lithium-ion is almost no memory effect. The so-called memory effect occurs in nickel-chromium batteries or nickel-MH batteries, these batteries are not completely discharged in the circumstances, produce a kind of crystallization reaction, which temporarily reduce the capacity of the battery, if you want to eliminate the memory effect can be several times the battery fully charged and discharged, it is likely to return to save the battery.

Some users have complained that certain features display battery capacity built in reliability is not high, because these products there is a special calculation chip Dell GK479 battery capacity. In general, the percentage of laptop batteries in the display still has a certain credibility, and should be noted that from time to time, it is preferable to conduct the calibration of the battery to correct the calculating chip battery capacity May contain errors. The calibration can be done through two methods: unplug the external power, turn off power management in energy saving mode and will self-discharge switch off your computer, use the BIOS or in calibration Random supplied by the associated software.

Another issue requiring attention is the use of the environment, while mobile computing is facing an environmental diversity, but at room temperature to ensure the use of battery life, or there are some advantages, too cold ambient temperature on the overheating laptops will be damage. In addition, when using a transaction processing power from the outside will only support the operation of the system while charging the battery so that the process of charging in the off state compared to the charging operation will be slower if you want to load, it is preferable to the state off.

In short, while careful not to use common power supplies swappable, calibrate the hp F4809A battery on a regular basis to work and try to operate at room temperature, then the laptop battery will stay with you longer.

The battery inside the moment any part of the solid material discharged by the batteries were pushed up more than 25cm distance, called the explosion. Determine if the Laptop battery explosion, using the following experimental conditions: The network covers an experimental battery, the battery life in the middle, away from the net on each side of the hood 25cm. Net density of 6-7 roots / cm, network cable with a diameter of 0.25 mm aluminum soft, if the experiment without solid part through the network mask to prove that the battery did not explode. Cause of the blast cells in general is:  

1, safety valves for unreasonable to fail to ensure safety.

2, charging the battery internal pressure are too high.

3, the battery has problems, such as N / P unreasonable, do not hear a battery will explode on the battery lead to fear. Indeed, as long as you use products (including batteries and chargers) is a qualified product, these problems would not exist.

Eligible products are backed by a rigorous control of the factory, and batteries and chargers have a charge and discharge protection device inside, even if the Dell Inspiron 6000 battery or charger, including a loss of protection performance, another also can also protect your battery will not overload, a phenomenon also responsible explosion does not occur. Even if the battery charger and protective devices are ineffective, if you find that the battery is very hot, stop charging and sent to the professional inspection will prevent this from happening.

User discussion about the cause of the battery exploding finish:

A saying:

1 may seal your well, intense chemical reactions. There is no gas to escape unharmed, he could skip the

2, burrs and dust caused by the micro-short circuits

3, is not the shipper problem?

4 is not equipped with anti-overcurrent (short circuit) using PTC

5, it should be the process of cell production does not control well, leading to swelling caused by perception and shorts.

6, batteries and chargers poor contact, resulting in excessive load-loader discharge protection within sampling (data) abnormal. Personal guess exposure is the main cause of the explosion!

7, the temperature must be considered when you’re likely to receive the hp Pavilion dv8000 battery temperature, especially in places like India, the battery and heat dissipation between the negative cable to the battery charger or the charger to heat the battery if the internal fault is likely to lead to internal short-circuit has evolved into the fire explosion, if the charger is not good at high temperatures may also lead to failure overload protection (provided that Internal battery protection against overload protection circuit is also null and void), is not strange if an explosion?

8, it may protect the board as tension problems.

In another way:

1, in fact, the cause of battery explosion, no analysis of several companies to emerge, most batteries factory did not make sense to get together and their online customers with reasons were acceptable.

2, can not find a better reason, remember to write the report must Yao insisted the explosion was an accident in the upper right is the correct path!

3, if there is an explosion in the discussion here can clear, I am afraid that nobody can make the battery a. Lithium is now the largest defect? Bang – trouble!

4, the capacity of lithium batteries is not too big to prevent the explosion turned into an offensive weapon!!

Referred to the prospect of a market for lithium battery, Linda, and Zhi-Ming Zeng agreed that the strong support the Chinese government. “The market is undoubtedly a very good prospect, and our policy is to support industry development.” They set this way.

Linda is a Frost & Sullivan research analyst, a perennial attention to new problems in the field of energy and Zhi-Ming Zeng are themselves working for an established manufacturer of lithium batteries – Beijing Anwar United Energy Technology Co., Ltd., all days are well aware of industry changes.

There is no doubt that their judgments are justified.

States consider that the Laptop battery and battery energy storage on the development of national strategic level, height, corresponding to the intensity of financial and political support to the fact that China favorably in this regard in the past, concern by nickel-metal hydride batteries, now put the eye more and more concentrated on lithium iron phosphate.

China Lithium-battery research ion and development projects has been the subject of 863 items, ranging from portable electronic devices with small batteries started 20 consecutive years of support.

Science and Technology Minister Wan Gang, the “2008 China Green Energy Summit Automotive Development Forum” given China’s goal of developing new energy vehicles – by 2012, China had 10% of the car production will save energy and new energy vehicles. The analysts calculated immediately, the Chinese manufacturer of lithium batteries is expected in 2012, the total value of more than 50 billion yuan to share the big cake.

In addition to political support, their judgments of this optimism are based on the superiority of lithium batteries in terms of their own.

It is understood that the Dell Inspiron 1526 battery power is present mainly in nickel-hydrogen batteries and lithium batteries are two kinds of hybrid forms of nickel-metal hydride batteries currently use more material, but due to nickel-hydride batteries metal have been a number of technical performance, close to the theoretical limit, therefore, not be considered in the future direction of development. In contrast, lithium-ion batteries due to high voltage, small size, light weight, energy density, no memory effect, no pollution, low self-discharge, the long life cycle, is widely recognized.

Since the business has continued to gain ground lithium-ion batteries have been in portable devices such as laptops, cameras, mobile communications are universally applied.

According to “2009-2012 China Li-ion hp F4812A battery report consulting industry” shows that China’s development of lithium-ion battery also has unique advantages:

In addition to lithium-ion battery itself has a performance advantage of lithium-ion battery for hybrid vehicles and pure electric vehicles, storage devices, energy, development of lithium-battery electric cars, our country has unique conditions, first, the benefits of resources. Li-electric cars, the most important components of key a lithium battery-power ion engine and permanent magnet synchronous, lithium-ion battery lithium the main material, manganese, iron, vanadium and other rich resources in our country. In China, the synchronous motor permanent magnet is permanent magnetic materials – the rare earth resources, power, lithium batteries for electric-car, provided that the hardware warranty. Secondly, the technological advantage. China low power lithium-ion batteries already industrialization, have formed a complete chain integrated upstream and downstream industry, the production of batteries for more than a third of the world market, lithium-battery technology ion has reached the international advanced level, industry-oriented conditions basically mature.

Thus, both characteristics of lithium-ion sony VGP-BPS5A battery itself, or the current situation of China, the development of lithium-ion battery would power industry of China’s new automotive main directions . Power on the future energy markets, lithium-ion batteries will be successful.

It is estimated that the mainstream nickel-metal hydride batteries will continue into 2011, but after 2011, Li-ion battery will gradually erode the market share of nickel-hydride batteries in metal. According to statistics, in 2008 -2009 years, the total domestic manufacturers of 50-60 basic devices will soon or have completed the purchase of production lines to achieve capacity expansion in 2010, the domestic auto industry to the early hybrid, iron phosphate lithium annual demand exceeds 15 thousand tons. Is expected that by 2012, annual national new energy vehicles will reach 1 million, when new energy vehicles in China will reach 70 billion yuan of output value of lithium batteries.

In recent years, global demand for lithium maintained rapid growth over the past three years, demand for lithium-up 25%, future demand for lithium batteries will consist of 20 percent annual growth rate. The development of lithium carbonate space will continue to increase. The coming years, the global lithium demand will be 5% -7% growth rates, the rate of growth higher than the level of global economic growth, showing that the global lithium industry is an industry stronghold GDP.
