The working principle of lithium-ion battery is that the internal electrolyte changes through chemical reaction, and there is a potential difference between the positive and negative electrodes to generate current. At low temperature, the electrolyte moves very slowly, which will affect the transfer activity of lithium ions between the positive electrode and the negative electrode, resulting in the decline of battery charge and discharge performance.
1. About discharge
1) The battery is not durable in winter
The battery is usually affected by the ambient temperature, and the discharge performance of the battery is better when the temperature is higher.
When the temperature in winter is lower than 0 ℃, the actual usable capacity of the lithium battery is lower than the normal temperature environment, which is obviously lower than before. However, don't worry. When the temperature rises, its function will recover naturally.
2) Cultivate good operating habits
According to Perry, a lithium battery manufacturer, the consumption of lithium batteries is much higher than that of low-speed constant speed driving. When the situation is not particularly urgent, it is recommended to drive at a constant speed to avoid sudden acceleration or braking
3) Do not overdischarge
In winter, estimation of battery power based on normal battery life may be inaccurate. When the battery power is about 20%, please charge it in time, form a good habit of charging when using, and avoid excessive discharge.
4) Avoid the battery from rain or water
Do not wade over the bottom of the battery compartment, otherwise water may enter the battery and cause internal short circuit. It is forbidden to charge the battery when it is immersed in water, otherwise it may cause ignition, combustion and explosion of the battery. The battery shall be charged after it is safe and completely dry.
