The invention relates to the field of electric vehicles, and provides an electric vehicle heat management system and an electric vehicle, which comprise a warm air loop, a motor loop, a battery loop, a heat pump air conditioning system and a first control valve group. The heat pump air conditioning system comprises an air source heat pump loop, a motor source heat pump loop and a battery source heat pump loop, the first control valve set is used for controlling on-off of all the heat pump loops, the outdoor heat exchanger is used for exchanging heat with the external environment, the liquid cooling condenser is arranged on the warm air loop, and the motor heat exchanger is arranged on the motor loop. The battery heat exchanger is arranged on the battery loop. Therefore, the passenger compartment can be independently heated by the air source heat pump, the motor source heat pump and the battery source heat pump, air heat, motor waste heat and battery waste heat are fully utilized, integration and coupling of all heat sources are achieved, the heat utilization rate is effectively increased, system energy consumption is reduced, energy waste is avoided, and the endurance mileage of the vehicle is increased.

    本发明涉及电动车辆领域,提供一种电动车辆热管理系统、电动车辆,包括暖风回路、电机回路、电池回路、热泵空调系统和第一控制阀组。热泵空调系统包括空气源热泵回路、电机源热泵回路和电池源热泵回路,第一控制阀组用于控制各热泵回路的通断,且室外换热器用于与外界环境进行换热,液冷冷凝器设置在暖风回路上,电机换热器设置在电机回路上,电池换热器设置在电池回路上。这样可分别独立实现空气源、电机源、电池源热泵对乘员舱加热,充分利用空气热量、电机余热、电池余热,实现各热源的集成与耦合,有效提升热量利用率,降低系统能耗,避免能量浪费,提高车辆续航里程。
