Embodiment 1
[0033] figure 2 It is a flow chart of a control method of a battery loop water pump in embodiment 1, such as figure 2 As shown, the control method of the battery loop water pump includes:
[0034] S101. Obtain the temperature difference between the target temperature of the battery module and the current temperature, and the duty cycle difference between the target duty cycle of the battery loop water pump and the current duty cycle.
[0035] Wherein, the target temperature of the battery module is the temperature that the battery module needs to reach, and the acquisition method may include: directly acquiring a preset temperature threshold as the target temperature, and a preset duty cycle as the target duty Compare. The current temperature can be obtained directly through a temperature sensor provided on the battery module, and the current duty ratio can be obtained through calculation based on the ratio of the high level on the battery loop water pump to one cycle.
