Problems solved by technology
[0002] In the related art, although the power battery thermal control method is based on the power battery temperature to determine whether to perform thermal control on the power battery, the control method is only a simple on-off control, that is: when the power battery temperature exceeds a certain set value, the thermal control The system heats or cools down the power battery with a single control method
It cannot meet the thermal control requirements of the power battery in different temperature ranges. At the same time, the control method is simply to control the thermal management system to control the power battery, without considering the efficiency and thermal control effect, resulting in the unsatisfactory thermal control effect of the power battery.
