The invention provides a thermal management method and device for an electric vehicle and the vehicle, and the thermal management method for the electric vehicle comprises the steps: when the vehicle is in an off-road working condition, determining whether the temperature of a vehicle battery pack and/or the temperature of a vehicle passenger compartment meets an execution condition or not; and if the execution condition is met, a vehicle air conditioner is controlled to stop cooling the vehicle battery pack, and/or the power of the vehicle air conditioner is reduced when the vehicle passenger compartment is cooled, and the vehicle air conditioner is controlled to cool a vehicle motor. Through the thermal management method of the electric vehicle, the purposes of prolonging the overtemperature time of the motor under the off-road working condition and ensuring the temperature resistance of the motor are achieved, and then the off-road experience of a user is improved.

    本申请提供一种电动汽车的热管理方法、装置及车辆,所述电动汽车的热管理方法包括:当车辆处于越野工况时,确定车辆电池包的温度、和/或车辆乘员舱的温度是否满足执行条件;若满足执行条件,则控制车辆空调停止为所述车辆电池包进行降温,和/或降低为所述车辆乘员舱进行降温时所述车辆空调的功率,并控制所述车辆空调为车辆电机进行降温。通过本申请提供的电动汽车的热管理方法实现了在越野工况下延长电机的超温时间、保证电机耐温性能的目的,进而提升用户的越野体验。
