1、the temperature is too low, the battery capacity decreases

Under normal circumstances, the best operating temperature of the battery is 25℃, and the usable capacity of the battery decreases by about 0.8% for every 1℃ decrease.

2、The battery charging and discharging ability is weakened

When the temperature is low, the charging and discharging capacity of the battery of the electric vehicle will be weakened, and when the temperature rises, this situation will improve. In winter, the temperature is low, and the power in the battery cannot be released. Generally, the power of the battery will drop by about 40%

3、The temperature of the battery solution becomes lower and the activity decreases When the temperature drops in winter, the temperature of the solution in the battery decreases, so does the activity of substances in the battery, which leads to low conversion efficiency and increased resistance, resulting in lower discharge voltage and faster power consumption.
