How to alleviate the attenuation of power lithium-ion batteries in new energy vehicles?

1. Operating temperature: Lithium-ion batteries are very sensitive to temperature. The best temperature range is narrow, and 0-40℃ is more suitable. Excessive temperature is actually harmful to lithium-ion batteries. However, at this stage, most pure electric vehicles are equipped with a relatively excellent temperature automatic control system, which can automatically heat up at ultra-low temperature, and there is also a relatively air-cooled type at high temperature. Water-cooled heat dissipation measures are solved, but if the working temperature is indeed too high or too high Low, the proposal is to let the pure electric car take a break. 2. The amount of battery charging current: What everyone often says is that fast charging and fast release endanger the service life. Let’s talk about fast release first. In fact, fast release is still very good. No one will open the big-foot plug-in switch. Application modules like gasoline cars are the same. Regarding fast charging, although today's new batteries are much better, the frequency of the circulatory system promoted and planned by manufacturers generally refers to the frequency of fast charging, but if you want to moderately increase the use time of rechargeable batteries, it is beneficial to use less fast charging. . 3. Concentration polarization condition (SOC): This kind of hazard is mainly the battery charging condition. Li-ion battery hates the battery charging condition, and the most suitable power consumption is around 20-80%, in fact like everyone's electronic equipment , Use as you charge, prevent the battery from running out of charge, so that the number of battery cycles will be increased appropriately. 4. Long-term storage: Long-term storage of lithium-ion batteries is not easy to have lithium-ion battery life. This is very simple, that is, the car cannot be left for a long time.
