Ericsson (NASDAQ: ERIC) and the operator Celtel cooperation of Uganda, to provide a new diesel battery hybrid energy solution. The solution can significantly help local areas outside the grid covered by mobile networks to reduce energy consumption, a reduction of almost 50% of operating costs of networks. Celtel Uganda was also the first application to use the solution provider. VGP-BPL8A  VGP-BPL9

Celtel Uganda is the local power grid is currently being used outside the coverage of diesel base station wireless replacement of all new hybrid energy solutions Ericsson and work with base stations Ericsson radio, outdoor cabinets apply. So far, over 100 sites to achieve such a transformation. In the past, a standard base station consumes about 20,000 liters of diesel per year, while the new solution will reduce diesel demand by 50%. Be reduced and the cost of transporting diesel fuel and storage, while overall operating costs of a single base station will remain lower in the future.

In Uganda, approximately 50% of base station wireless must use diesel oil as main fuel. Many high-growth markets, will also be diesel main energy sources, especially those in electricity supply shortage or unstable areas, such as remote villages.

Traditional non-grid diesel solutions are supported by two diesel generators working alternately. Ericsson’s new hybrid energy solution, in which a diesel generator will be replaced by a battery specially designed to handle a large number of charge storage and output.

Hybrid energy solution Ericsson is a stand-alone power solution that can recharge the battery via the configuration storage and output to achieve the highest level, thus prolonging the life of batteries and generators.

Celtel Uganda, Siyabonga Zulu chief officer of operations, said: “We operate in the work of Uganda in the full deployment of the hybrid energy solution Ericsson. The solution to the cabinet to provide a reserve battery more powerful and weak energy consumption of cooling device, and to help us cut 50% of diesel consumption. energy saving effect is very important, and we will extend cost effective network for people who have never been contact with the mobile networks to provide network coverage. ”

Ericsson site Solutions strategic product manager for Kent Westergren said: “This kind of customized solutions for users in the market response is very good, because it significantly reduces operating costs, and reduce the impact on the network environment. Generally tend to base station because of too big to operate solely on solar energy, for those who want to reduce costs or the emergence of green operators, this solution is an excellent choice.

Ericsson diesel electric hybrid power solution is a series of F3172A PB995A energy optimization innovations for the latest product. Ericsson hopes that the series of products to help operators to reduce overall costs while improving mobile networks in the world in environmental performance of the growth process.

In 2006, Ericsson will be the last generation of WCDMA base stations to reduce energy consumption by 35%, and the breakthrough introduction of a number of alternative energies, as in the use of telecommunications solar and biomass, which makes mobile communications in BATCL50L  LCBTP03003 emerging markets is more economic, environmental.

KDDI launched models of mobile phone brand in 2009 summer “SOLAR PHONE SH002. Sharp is the main features of this phone is the first time in Japan back in the chassis is equipped with a solar toshiba PA3191U-3BRS battery module. In emergency situations such as battery margin is equal to zero, it can be used as an auxiliary power source. “Prosecution sun for about 10 minutes when the call lasts about 1 minute in standby could insist on approximately 2 hours (KDDI).

SH002 is also a charger, it also equipped with a reception at single band, FeliCa e-billing capabilities, the GPS receiver and Bluetooth transceiver functions such as high-end mobile phones in Japan, all features function of “full” model. And also has a resistance level IPX5/IPX7 water. Produced with the assistance of technical personnel has been dismantling.

Anti-noise solar battery module

First, look at the screen with a parts of the solar battery module. Sharp is equipped with solar A1008 battery module development. Dimension of about 67.5mm x 41.0mm x 0.8mm. To achieve the thickness of 0.8mm, using the technology of semiconductor packaging. “Whether domestic large-scale solar battery module thin. Tectonics completely different” (technical staff, a Japanese manufacturer of solar battery).

According to Sharp this conversion efficiency of solar battery modules is 13%, the maximum output power of 300mW Note 1). The output voltage of 4.5V, the voltage can be used for lithium-ion batteries. “10 The output voltage of 0.5 V solar battery polycrystalline silicon serial (the technical staff above). Module grounding has 9 dorsal electrode. Assisting in the dismantling of Japanese manufacturers of mobile phones and technical staff to speculate: “module of solar batteries may play a role in the antenna can easily generate electromagnetic noise. Thus, to take an anti-noise measurements. “

Shows part of the chassis is equipped with features of low power consumption of 1.1-inch monochrome e-paper. Solar battery module can display the feeding process with the performance when loading and free talk time. E-paper with a bright side to sensors, from the values obtained in the module’s electronic paper display in the use of solar BATCL50L batteries in the process of charging efficiency.

SH002 The main emphasis on two motherboards to PCB. RF circuits, digital circuits, signal processing, etc. Almost all major components encapsulated in the side of the motherboard. Vice-package-board, single module single band tuner and FeliCa with sending and receiving circuit. Components on the motherboard, such as RF circuits, power circuits and circuits for digital signal processing and so uniform. “It is very common in models of high-end Japanese components configured” (The Japanese manufacturers of mobile phones and technical staff).

The motherboard for mobile phone chips Qualcomm “MSM7500. It is the use of a high-pass and KDDI mobile phone to develop a common platform ‘KCP +’ standard chips, but also integrated into the GPS transceiver circuit. Sharp models from the summer of 2008 “W62SH” has begun to support KCP + terminals. Telephone main circuit follows the design of the original models, but their main efforts on the packaging of solar VGP-BPS2A battery modules.

Various methods of sealing the upper and lower casing

Equipped with solar battery modules, in addition, SH002 Another important feature is resistance to water IPX5/IPX7-level. The upper and lower waterproof case to achieve in different ways. Shows part of the chassis used is to use double sided tape on a frame with LCD panels and solar battery module sheet structure mask.

The keyboard side of the chassis used in both chassis and battery cases, respectively, between the folder structure in the filling of waterproof rubber for resistance to water. The side of the keyboard chassis material is fiberglass reinforced nylon resin off. In both upper and lower case are two ways of seeing “is also waterproof handheld products to achieve a very common approach” (The Japanese manufacturers of mobile phones and technical staff).

Improving the robustness of the measures is also equipped with rechargeable batteries can be seen. SH002 is equipped with lithium-ion rechargeable battery electrode is used in the shrink wrap on the motherboard to connect the terminal building. Japanese mobile phone rechargeable batteries typically radiate a flat electrode. The Sharp by changing the electrode structure so that when the phone slipped under circumstances such as poor contact of the battery has been defused. This electrode structure, Finnish Nokia and other handset manufacturers have adopted from abroad through the national mobile phone in Japan is also very rare “(technical staff above).

As the vehicles most promising of electricity from lithium-ion Laptop battery, lithium iron phosphate power battery has excellent safety, long cycle life, high energy density advantages. But how to improve the performance of its magnification to improve its high temperature characteristics, so as to satisfy the hybrid electric vehicles and pure electric vehicles, the use of demand is the lithium iron phosphate manufacturers are faced with important questions . Improving the performance of the supply of lithium iron phosphate, high performance and low temperature, the first approach is positive and negative materials, nano-technology, doping and carbon coated, followed by selection and the rational use of conductive agent, 3 to choose low electrolyte temperature, of course, a structural design reasonable, a reasonable choice gap, this article introduces the agent driver in the application of lithium iron phosphate describes how a reasonable choice conducting agent, how wise use of the conductive agent, thereby enhancing the lithium iron phosphate for high performance and low temperature performance and a magnification to prolong the life of lithium phosphate iron.

The lithium iron phosphate work

Lithium iron phosphate does the following diagram -1 and -2 shows the following pattern:

1, charge a Li + crystals of iron phosphate lithium surface 010 of crystal migration to the surface under the action of the electric field strength in the electrolyte through the diaphragm, and then migrate through the electrolyte to the surface of graphite crystals, and then incorporated in the crystal lattice of graphite. At the same time, e-flow positive response by the conductor of the collector foil after an ear, the pole of the sony VGP-BPS2 battery and the external circuit, the negative, the flow of anode copper anode set of ear fluid, and flows then through the conductors of graphite anode, so that negative electrical Heda balanced. Lithium iron phosphate lithium-ion elimination of the inlay, iron phosphate lithium iron phosphate, its structural changes in the trellis diagram above -2.

2, the battery discharge, Li + de-embedded crystal graphite in the electrolyte through the diaphragm, and then migrate through the electrolyte to iron phosphate crystals of lithium on the surface, then re-integrated into surface by 010 lithium iron phosphate in the crystal lattice. At the same time, the battery passes through the conductor collector of copper cathodes, after an ear, the battery negative column, outside the circuit, the positive pole, the positive ear flow VGP-BPS10 battery cathode current collector sheet aluminum and circulate through the iron phosphate conductive body lithium anode, so that the positive electric Heda balanced.

Lithium iron phosphate from works that we can see that the lithium iron phosphate loading and unloading process is lithium ion and electron to participate, and lithium-speed migration of ions and the speed migration of electrons to strike a balance. This requires positive and negative electrodes for lithium-ion conductor mixed ionic and electronic and ionic conductivity and electronic conductivity must be consistent. But we all know, the conductivity of iron phosphate lithium poor performance. The conductivity of the graphite anode, while the best, but to achieve significant rates of rejection, we still need to improve cathode conductivity, so that the electronic conductivity of lithium ion-embedded in graphite the ability to find a balance.

To meet the lithium iron phosphate positive and negative conduction problems, it must be added to the battery positive and negative conducting agent, so that the active ingredient in the formation of battery model in Figure -3 and figure 4 SEM photographs shown in the effective conductive network. 2 if the BATCL50L battery capacity of ion conduction that I set, the electronic transmission capacity set to E, then in theory I = E, 3, to ensure the battery charge and discharge process, the burden of maintaining homeostasis: I = I = cathodic electrolyte I = I divide electrolyte cathode = I, E = collector anode-cathode current E = E = ear very CRT-chu E = E = external circuit cathode E-chu anode = E = ear E = E anode from the cathode current collector. (This equation is actually three lithium-ion battery designed for an important principle, but the actual process of design and production process itself, how to achieve these three equations, but also need to develop a series of experiments to verify a mathematical model or an empirical formula, and then these models, or formulas to achieve the design of lithium-ion battery)
