[0130] In this embodiment, as Figure 14 shown, start the battery refrigerant heat dissipation loop and the motor low-temperature heat dissipation loop simultaneously, so that the heat of the motor driving mechanism 9 is dissipated by the low-temperature radiator 3, and the battery is cooled by the air conditioner.

[0131] In a possible implementation manner, as Figure 2 shown, the heating module further includes a first battery heating loop;

[0132] The first battery heating loop includes a plate heat exchanger 43, the five-way valve 11 and the third water pump 12;

[0140] In this embodiment, as Figure 17 shown, the motor heat storage loop and the first battery heating loop are simultaneously turned on, so that the waste heat of the motor can heat the battery.
