The invention provides a self-cooled power assembly, an electric vehicle and a vehicle temperature control system and method, and relates to the technical field of electric vehicle temperature control. The self-cooled power assembly is suitable for the electric vehicle and comprises a motor, a radiator and a mechanical liquid pump, and the motor is used for driving the electric vehicle to run; the radiator exchanges heat with a heating device of the electric vehicle, cold liquid is driven to circulate in the radiator through the mechanical liquid pump, and the mechanical liquid pump is in transmission connection with the motor. The heat dissipation efficiency changes adaptively along with the vehicle speed, power does not need to be supplied to the liquid pump independently, the problem that the electronic liquid pump is prone to electromagnetic interference is avoided, the heat dissipation reliability of the power assembly is improved, heat dissipation pipelines can be simplified, and the layout design difficulty of a vehicle chassis is lowered.

    本发明提供了一种自冷式动力总成、电动车辆、车辆温控系统及方法,涉及电动车辆温控技术领域,本发明提供的自冷式动力总成,适用于电动车辆,该总成包括:电动机、散热器和机械液泵,电动机用于驱动电动车辆行驶,散热器与电动车辆的发热器件换热,通过机械液泵驱使冷夜在散热器内循环流通,机械液泵与电动机传动连接。实现了散热效率随车速自适应变化,无需单独为液泵供电,且规避了电子液泵易受电磁干扰的问题,提高了动力总成的散热可靠性,有利于简化散热管线,降低了车辆底盘的布局设计难度。
