Over the next few years an attractive alternative to lithium-ion batteries

The advantages of lithium-ion technology in energy density, power density and efficiency have resulted in a triumph of this technology for consumer applications. For automotive applications, allowing the higher energy density, compact and lightweight battery systems. The high performance, better electrical performance and improved efficiency to reduce fuel consumption and simultaneously, often power-limiting heating of the Dell Vostro 1510 battery cells decreased.

For traction batteries in motor vehicles systems with many single cells required to achieve the necessary performance.
The environmental conditions and life requirements in cars are much harder than in the consumer world. Risks that may result from the high energy density of lithium-ion cells, safely rule out measures in the Dell Latitude E5500 battery cell and battery management system are needed, their effectiveness can only be detected in time-consuming life tests.

In the more performance-oriented hybrid applications, the advantage of higher energy density of lithium-ion cells nutzbar.Vorteile limited stem more from the lower Dell Latitude d620 battery weight, and the somewhat better efficiency than nickel-metal hydride permits a higher electrical load in the natural cooling system. For these high-performance batteries today only nickel-metal hydride cells can be used. Due to the still existing significant cost advantages, the robustness of the technology and life experience, the nickel-metal hydride technology will be in the coming years, an attractive alternative to lithium-ion batteries.

For electric vehicles or plug-in hybrids if high energy cells can be used which can store very large amount of electrical energy. Here is the range and therefore the energy content of the Dell Studio 1537 battery system the key. With high pressure so many battery manufacturers are working on the development of large lithium-ion cells with high energy capacity between 20 and 80 amp hours. The requirements for safety and life of the cells are, represent the greatest challenge and require a lot of know-how in materials development and manufacturing processes. These cells can develop battery systems for the first time, allow the ranges of 100 kilometers and more in the electric drive mode. Plug-in hybrids and electric vehicles will therefore be in the next few years on lithium-ion technology has no serious alternative.
