The Important Features for Lithium Battery

There are five key elements of lithium batteries, namely, cost, electricity storage, dynamic density, safety and lifetime. Whether electric vehicles can attract customers or not is largely determined by price, while batteries are the most expensive component of electric vehicles.  

Another key element of popularizing electric vehicles is the maximum distance determined by battery storage capabilities. The distance requested by the customer is two hundred kilometers. To meet this requirement, engineers try to strengthen storage capabilities.

Experts point out that changing the chemical composition of Lithium-Ion batteries is a good way to increase electricity density. The most advanced battery distance is 100 to 150 kilometers.

In addition, battery life must be as long as the car. For electric vehicles, the battery charging circuit must reach one million times, because the switches between the motor and the engine are very frequent. The ideal complete charging circuit must be 1500 to 2000 times, that is, each battery charge can travel 150 to 200 kilometers.

The lifetime of lithium batteries is more than ten years. No need to change it if the performance is not lower than eighty percent of the original percentage. Safety must also meet high automotive industry standards. Interior materials play an important role in safety; take the separator for example, if the temperature is too high, the device will stop the current without stopping.

Battery management is very important, which is capable of recording and adjusting current, voltage, temperature and electricity. Therefore the battery will not overheat and lose electricity. A smooth battery management system keeps the battery in a safe temperature range.
