As environment-friendly vehicles worldwide are sought, the hybrid electric cars and sells the next few years, the automotive VGP-BPS10 VGP-BPS2A battery market is booming. “It is predicted that by 2014 the market size will expand rapidly to 2.25 trillion yen (about 24.8 billion U.S. dollars), is about 215 times in 2008.” He is a professional market research agency Fuji, Japan Economic Research Institute has recently taken statistics.

 

Reducing emissions and oil resources in response to the twin pressures of an increasingly scarce in most countries, the development of new energy vehicles will be seen as a revitalization of the domestic auto industry and energy savings of how the most important, while reducing the more stressful, and the United States for promoting the flagship development of new energy vehicles. Recently, China and the United States issued the “Joint Declaration”, said that both parties will be launched at the initiative of the U.S. electric car, the two countries in years to come, more 1 million electric cars used.

 

In China, in March last year, “issued by the restructuring of the automotive industry and the revitalization of planning” in the development of new energy vehicles have also developed a broad target – the next three years, China will form a plug 500,000 electric hybrid type and common hybrids Energy Qijuchanneng. In 2012, the new production vehicles, there will be 10% energy saving and new energy vehicles, vehicles with new energy should reach 500 billion output value of RMB.

Faced with such an interesting cake market, prices of domestic cars, spare parts and other upstream companies have exposure to these products to very good early position. Compared to conventional vehicles, new energy vehicle technology gap with foreign countries do not, it is possible to exceed bend over to help companies involved to increase investment in new optimism energy vehicles . Among them, the battery powering the vehicle – lithium-ion battery is a major R & D related to the target.

 

It is understood that the current hybrid cars use nickel-hydride technology battery metals major, but the nickel-metal hydride battery a number of technical features such as energy density, charge and discharge rate is close to its theoretical limits. The lithium battery has an energy density, high capacity, no memory, etc., are car manufacturers and battery suppliers unanimous support of the current national focus on R & D is the lithium-ion batteries .

 

According to the different cathode materials, lithium batteries are cobalt oxide, lithium, lithium manganese oxide, ternary materials, and four types of lithium iron phosphate. Lithium iron phosphate is the best hybrid vehicle using lithium cathode materials. Currently, prices of cars in China introduced models in purely electric vehicles, batteries power batteries are lithium, Chery, BYD uses iron phosphate lithium. PB991A PB992A

 

Although China Li-ion battery production ranks third in the world, but in products, and technical level with Japan, the United States, there is a certain gap, the lithium batteries of the automobile are not yet in the industrialization of the essay. Xinhua noted that the letter and other research institutions, China’s relatively backward production facilities of battery power, many companies focus on the subject, ignoring the improvements of the manufacturing equipment . At present, China will depend mainly on the production of batteries and equipment imports expensive, which is our development of battery power vehicle is very unfavorable power batteries in mass production It should be equipment for advanced automation, the focus of advanced research. In addition, most independent research firms in China A1078 A1175 battery power and development, funding is limited, only the fundamental problems to solve cell technology is difficult to advance further. Lack of adequate communication between businesses, all want to know the circumstances of other people do not want to talk about their own experiences, there is widespread low-level study of the phenomenon of repetition.

We well known that the rapid development of mobile terminals is currently the main bottleneck is the question of battery life, whether laptop, cell phone or MP3 and so on. Especially in our lives play an increasingly important role in the cellular phone and a laptop, the Laptop battery life, a greater impact. In mobile phones, although there are some known as “10 days, or January” long wait for special items, it is often separated from the practical application of the extreme intensity data, and it is not practice. Now, the majority of mobile phone battery may be necessary to maintain the intensity of use 2-5 days, while the feature-rich and powerful smart phones are often in 2 days. For users, the ability to initiate such a life is a recurring charge of ongoing unrest.

 

To solve the battery problem, scientists worldwide in the ongoing efforts, we have reported previously, such as zinc manganese batteries, solar cells, or new technologies. Although the solar cell manufacturers have already started using mobile phones, but the cost and actual results are not very satisfactory, while the cost of the fuel cell is higher, universal access is very difficult.

 

Replacement Dell Inspiron B120 battery lithium technology, which has recently emerged a new wave of forces: zinc-air batteries rechargeable. In fact, zinc battery technology of the air has been invented over one hundred years of history, the use of activated carbon adsorption of oxygen in the air as the cathode active material, zinc as anode, ammonium chloride or caustic soda solution, the electrolyte. The 20th century, the sixties caused due to technical space technology, the zinc air battery has started to enter the practical application. Today, many of button batteries used in hearing aid is in fact one of the zinc air battery.

 

As zinc and hp PB992A battery constraints of structural air, has long been unable to achieve the recycling of rechargeable battery technology. In recent years, research institutions SINTEF Norwegian zinc electrode through the improvement and control of internal moisture to reach the zinc air battery charging technology. The current zinc batteries, battery air have been made in the experience of more than 100 charges expectancy discharge cycle life for lead at 200 times. Compared with lithium, zinc air rechargeable batteries is its ability to store three times the cost of half of lithium batteries, and absolutely no security risk of overheating of the explosion.

 

SINTEF was established in Switzerland in charge of zinc ReVolt development of the battery from the air and the commercialization of rechargeable products. The company said for hearing aids, miniature zinc air rechargeable batteries will start selling next year, may be used for mobile phones and other mobile devices, zinc-air rechargeable batteries will be introduced later. For market-dependent life expectancy at discharge should be 300 to 500 times. According to lifetime tenure, if each manager can provide three times the life of the battery current (based on 6 days counted), 300 to 500 times the life span is 1800-3000 days, over 5 years. Oh, for the life cycle of today’s mobile base in 2-3 years is enough. Hopefully this technology cans really only the beginning of the realization of Oh!

HP laptop / No Comments

The annual sales income over 100 billion U.S. dollars, operates in all key areas of the computer industry, Hewlett-Packard, took first place in the PC market after the quality of their products they are often caught in the crisis of confidence in the brand, following the charts, screens, batteries, etc. took place after a dispute over the quality, the most recent case is that HP E9105t models desktops and improved hp 367759-001 battery version of the computer problem E9108t blue screen, which is currently abroad caused dissatisfaction of many users.

 

“Economic Daily News” reporter has learned that hundreds of overseas customers have been planned collective complaints and its improved version of the HP E9105t E9108t computer problems blue screen, which Hewlett-Packard of China public relations person in charge of enterprise PSG accept the “Daily Economic News” reporter, said that since the two desktop products are not available in China, so the issue has no impact on users china. However, according to “Economic Daily News” reporter has learned, in fact, even before this incident, HP “Blue Machine” was published in the Chinese hp Pavilion ZE2000 battery market.

 

It is remarkable that in recent years has been consumer complaints about product quality and in case of HP, and more incidents of overheating of the battery were treated reminder of HP, other users of computers in question were not the ideal treatment, which also allow the quality of HP after sales service widely disputed.

 

There are also Hewlett-Packard machines to blue screen”

 

According to Zhongguancun in Beijing, and outside on the streets of the computer channel will present the city from April 2007 onwards, due to “sudden Hewlett-Packard cut prices of all models, “then HP laptop sales in Beijing and the computer market in the country showed an eruption.” Zhongguancun channel Wang Jun (a pseudonym) Analysis: “HP is a great hp Pavilion dv4 battery brand, previously, price is always higher than other brands when the price low, people buy more naturally.”

 

However, the top of its price cuts come with HP sales eruption “lasted only a few months.

 

According to Wang Jun, the second half of 2008 to begin buying prices fell Series V3000, DV2000 Series, compaq6000 series models such as the use of laptop users there, where a variety of models V3000 series a “blue screen of frequent and automatic restart” issue.

 

June 2007 Hewlett-Packard model V3159 bought in Zhongguancun, laptops, said Mr. Ho, his notebook in early 2008 began to emerge from the blue screen phenomenon, from November 2008, began to frequent blue screens all the day there will be two three. He suspects the software blue screen may be caused by the conflict, if Ho reinstalls the system several times, but he told reporters he was trying to install a variety of operating systems, the two hp 338794-001 battery can not solve the problem blue screen.

 

Press investigation revealed that this phenomenon occurs not only in Beijing, Guangxi, laptop users HP V3000 presented by Mr. India, and V3000 is the beginning of last year in Nanning to buy Electronic Science and Technology Square, since the use of ordinary blue and death, he worked this get your own laptop service centers HP Care Pack requires an interview, but the other party asked for blue screen when the new portable-Na Qu interview, Mr. India and it is difficult for him to accept HP product of the attitude of consumers of services hp PB992A battery.

 

Wang told the “Daily Economic News” journalists, HP handheld products, sales decreased significantly in the second half of last year, “the time there was a big snow-screen events so much noise, much of ‘buyers were interested in the Hewlett-Packard in consultation with the change after the other brands, but in 2007 sold the shipment of high rates of repair, so we reduced the volume of HP in general take is someone takes on the basic non-prepared stock. ”

 

Bad motherboard problem? HP does not take

 

Mr. Ho and India revealed that in the face of the HP laptop blue screen problems, they have posted online with people to discuss and find solutions. “Most experts agree that this is not a software problem caused a blue screen, the problem probably lies in the motherboard of the machine.” They said.

 

Coincidentally, a few days ago by the blue screen problems abroad, Hewlett-Packard desktop users out of this under the same conclusion.

 

July 19 of this year, claiming to be Cee Cee-users in HP technical support forum post to talk about his new hp F4809A battery July 10 Hewlett-Packard bought e9150t office nine days time, “the strike met 10 times . Cee-Cee question in this post 3 months after October 19, citing the response has already had up to 193, there are hundreds of users described in this quote their own use within the office e9150t HP and blue screen appears e9180t, automatic restart, and questions of the accident, there are 122 users have scheduled a joint complaint on the issue, has asked HP for a replacement computer.

 

In the posts, many users have reported having tried a variety of methods to identify the root causes of blue screen, and use different settings and drivers, switch to a different operating system, but the screen problem Blue is still pending. In their view, the most likely outcome of a blue screen problem is the motherboard. According to the poster says, e9150t and e9180t use the model of motherboard pegatronIPMTB-K.

 

While mobile users in China and office users abroad, the blue face of problems are always the product of the Board of Directors of HP has raised questions about quality, some users think of other HP products may be due to the same type of motherboard and the emerging problem of blue screen, but the press before, Hewlett-Packard had not yet been placed on the “Daily Economic News” highlighted “China in the HP products hp PB995A battery listed, use the same models that are used by pegatronIPMTB e9150t and e9180t model – K, motherboards,” “The products in question to a blue screen, HP will remember,” responded positively to these questions. HP said only that the two previous office products are not available in China, so the issue has no impact on users in China.

 

Quality of service has been criticized

 

It is noteworthy that Hewlett-Packard, not only did not respond positively to the blue door, but also for older graphics cards, door, screen door flashing, the screen door snowflake models involved are so far failed to take the recall, or other hp 346970-001 battery measures. The HP Service Department Gold service quality service center, since the snow on the screen since the incident came to light is also widely criticized.
