digital batteries

Hitachi Vehicle Energy, Ltd. which develops and manufactures lithium-ion batteries for automotive applications, such as hybrid electric vehicles, have developed a lithium-ion battery having the world’s highest power density of 4,500W/kg, 1.7 times the output of the company’s mass-produced, automotive lithium-ion batteries. Sampling of the new battery by domestic and overseas car manufacturers will start in the fall. 

To reduce internal resistance, the battery employs a new manganese cathode and an original Hitachi battery structure, in such as thinner electrodes, power collection method and effective configurations to achieve the world’s highest output.

In recent years, lithium-ion batteries have been used for many consumer product applications, including mobile telephones, notebook PCs and digital cameras. For the same energy density, a lithium-ion battery has about half the volume and weight of a nickel-metal hydride battery, and about one-third the volume and weight of a lead acid inspiron battery. This makes the lithium-ion battery a small, light, high-energy-density secondary battery that is attracting attention for its applicability to hybrid and electric vehicles.

In 2000, the Hitachi Group used its extensive technological and manufacturing capabilities in fields ranging from materials to battery control systems, to develop and mass-produce the world’s first safe, high-performance, long-operating-life lithium-ion battery for automotive applications.

A second-generation lithium-ion battery with a power density of 2,600 W/kg that currently is being delivered for automotive and railway applications is the world’s only mass-produced lithium-ion VGP-BPS2B battery for on-board applications. Up to this point, a total of some 600,000 cells have been delivered, mainly to car manufacturers and railway companies. 

Moreover, development of a third-generation lithium-ion battery having an even higher power density (3,000 W/kg) has already been completed, and will go into mass-production in 2010, with deliveries scheduled to begin the same year. 

The battery set to start sampling this fall has been developed as a fourth-generation lithium-ion battery that is even smaller and lighter yet able to provide the world’s highest output. The high reliability of the new battery, in terms of mass-production and quality, is the culmination of manufacturing technology that Hitachi has built up in the course of its extensive market achievements, and through the feedback from its customers.

Going forward, in addition to this lineup of stand-alone battery cell products, Hitachi will meet customer needs by providing optimal battery system solutions that include control systems.

 In line with its long-term “Environmental Vision 2025″ plan to combat global warming, the Hitachi Group is using the expansion of its systems business, starting with its battery operations, to make a contribution to the future of the global environment, and to strengthen its social innovation business.

 Motor vehicle users increasing, but most users of electric vehicle batteries, but they are very small. In fact, the batteries of electric vehicles as one of the four elements, the use of taboo is very large. An electric bike, always present in the technical development of a film, the most important event is the battery. Thus, to understand the use of the battery to maintain, require caution.

Rechargeable batteries have serious implications for improper right

Some people said, “But the rechargeable battery is not bad with the bad, this statement really has its own validity. Charging the battery performance good or bad for battery life and use of performance plays an important role, we must attach importance to recharge so. The vast majority of where the user, the best option for the battery to discharge a depth of 50% to 70% of the best to recharge a Latitude battery so that battery life can achieve the best results. At the same time, the impact of temperature on the load is large enough. In the high temperature season, recharge the battery problem existed. Should try to reduce the battery temperature to ensure good heat dissipation to avoid sun exposure after charging batteries under the sun will the temperature increased, the battery increases the activity of various active substances that affect battery life. In contrast, low temperature, the charge acceptance of the difference of the battery is the problem of inadequate care, in which case, we must improve the charging voltage and extend the charging time and take measures for the isolation of antifreeze, so it can help to ensure sufficient power to prolong battery life.

Avoid short circuit and over charge-discharge

Drums in the state short-circuit, short-circuit current of up to several hundred amperes. Light that causes fever, severe cases can also cause battery explosion. Therefore, by installing or using the battery must be particularly careful to check the phenomenon of non-short-circuit, after then put into service. At the same time, as indicated above misperception of batteries caused the damage, but excessive load or unload the damage will be important to batteries, power efficiency and battery life cycle of the company. Experts said the batteries overload will increase water loss, accelerated grid corrosion and softening active ingredient, which increases the risk of deformation of the battery. Do not overheat the battery environment. And wait until the temperature returned to normal when the battery before recharging. Found that overheating should be to stop charging and chargers and batteries must be checked.   

Proper maintenance to prolong battery life

Proper maintenance can make a longer life battery and put more input. They should pay attention first to the VGP-BPS2C battery installed securely fastened to avoid riding where about battery damage due to vibration. Otherwise, the car driving on bumpy roads, causing damage battery jig or even fall. Secondly, we must always check the battery cable, connector live is strong, the line is between good contact with the connector. Otherwise, we will probably spark electric battery causing a serious explosion.

At the same time, always remove the battery cover from dust, dirt, be careful to keep the battery dry, clean, to prevent battery discharge. In stock, we must be careful not to let the battery discharge when the lights display battery charge just a show, they should immediately charge the LCBTP03003 battery to avoid battery drain. Even when the man began to cultivate and help recharge the battery every night, good habits.

According to Japanese non-governmental investigative agencies Yano Economic Research Institute recently released report shows that in 2008 global production of solar batteries increased from 69.5% to 6.505GW, however, due to restrictions of Spain on the FIT (Feed-in tariffs, electricity utilities to buy solar energy to top The new generation of electrical power) scale political ally to the U.S. financial crisis triggered by the aftermath of the recession World Economic spreads currently on the market for solar batteries, it estimates the 2009 Global production of solar batteries will 8.295GW, annual growth rate of only 27.5%, much less in 2008 to nearly 70% growth rate .

Solar batteries on the terms of types, forecasts for 2009 production of solar batteries crystalline silicon will grow by 20.0% to 6.715GW (the proportion of the total production of solar batteries 81.0%), thin Silicon estimate film solar battery production by 40.0% this year 500MW (6.0%), CdTe solar battery production estimate of 78.7% this year 900 MW (10.8%), battery production CIGS solar is also expected to increase 260.0 years per cent to 180MW (2.2%).

Yano said the market for solar batteries in 2009 despite the impact made by the stagnation of the economy showed reduced growth rate, provided that this is a temporary phenomenon, monitoring issues such as prevention global warming continue to simmer, the solar battery market should continue to grow. Yano also said that while market monitoring of solar batteries should continue to grow, but to enter the solar battery market as suppliers continue to increase in the past continue to successfully expand the market share of large companies will also be a bitter fight on the solar market future of the old “set on the sold out” to “how to sell” the situation.
