The invention relates to the technical field of thermal management of hydrogen energy vehicles, in particular to a whole vehicle thermal management system of a hydrogen fuel electric vehicle, a control method and the vehicle. Comprising a fuel cell cooling loop, an air conditioner warm air loop, a power cell temperature control loop, an air conditioner refrigeration loop, a motor heat dissipation pipeline and a motor and accessory temperature control pipeline. The fuel cell cooling loop, the air conditioner warm air loop and the power cell temperature control loop are connected through a five-way valve, and heat exchange can be carried out between every two or among the fuel cell cooling loop, the air conditioner warm air loop and the power cell temperature control loop; the power battery temperature control loop, the motor heat dissipation pipeline and the motor and accessory temperature control pipeline are connected through six-way valves, and heat exchange can be conducted between every two of the six-way valves. The problem that in the prior art, fuel cell heat management, power cell heat management, motor and high-voltage electric accessory heat management and a cab air conditioner work independently, and consequently heat is wasted can be solved.
本发明涉及氢能源汽车热管理技术领域,具体涉及一种氢燃料电动汽车整车热管理系统、控制方法及车辆,该氢燃料电动汽车整车热管理系统,包括:燃料电池冷却回路、空调暖风回路、动力电池控温回路、空调制冷回路、电机散热管路和电机及附件控温管路;燃料电池冷却回路、空调暖风回路和动力电池控温回路通过五通阀连接,并可两两之间或者三者之间进行热交换;动力电池控温回路、电机散热管路和电机及附件控温管路之间通过六通阀连接,并可两两之间进行热交换。能够解决现有技术中燃料电池热管理、动力电池热管理、电机及高压电动附件热管理和驾驶室空调都是独立工作,导致热量浪费的问题。
