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.

The invention provides a power battery thermal management control method, a power battery thermal management system and a vehicle. The power battery thermal management control method comprises the steps of: detecting a power battery temperature and a cooling medium temperature; determining a corresponding temperature control mode according to a temperature interval in which the power battery temperature locates and the temperature of a cooling medium, and adjusting the power battery temperature to a target temperature according to the determined temperature control mode, wherein energy consumption of different temperature control modes is different. The power battery thermal management control method provided by the invention can realize the optimization of power battery temperature control, reduces the energy consumption, and controls the power battery temperature within an optimal operating temperature range.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a power battery thermal management control method, a power battery thermal management system and a vehicle. Background technique [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, which leads to the unsatisfactory thermal control effect of t...
