Why is the performance of electric vehicle battery declining in winter?

Charge and discharge is a chemical process that requires certain temperature conditions. Any battery, at low temperatures, the chemical activity inside will be reduced to varying degrees, the chemical reaction is slow, so the winter weather is cold, the battery capacity will be reduced a lot, this is a normal phenomenon.

In winter, due to the temperature below 0 degrees, the battery performance of many electric vehicles is greatly reduced, and the mileage is greatly reduced. This problem can be solved to some extent with hot water bottle + quilt. In the 20 minutes before the car, use multiple large hot water bottles to fill the boiling water, place it around the battery, and then wrap the battery + hot water bottle with cotton quilt to reduce the heat outflow. The hot water bottle should be sealed to prevent short circuit caused by water leakage. It is also possible to replace the hot water bottle with a plastic beverage bottle or a kettle.

Note here: If you encounter rain and snow, this time the humidity is high, the battery leakage current will increase, and the discharge will affect the life. You can wipe the whole appearance of the battery and keep it dry, especially the charging interface. . The charging time in winter can be longer than the summer. Try to ensure that it is more than 8 hours, but it should not exceed 12 hours. Generally, it will float for 2 hours after turning the light.
