The invention relates to the technical field of hybrid electric vehicles, and discloses a 48V hybrid electric vehicle thermal management system and a hybrid electric vehicle. The invention provides the 48V hybrid electric vehicle thermal management system. A first heat dissipation channel and a second heat dissipation channel which are independent of each other are arranged in a radiator; a firstpump body, a 48V power battery and the first heat dissipation channel are sequentially connected in series to form a low-temperature cooling loop; when the 48V power battery does not have high coolingrequirements, the 48V power battery is cooled, and meanwhile, a second pump body, an electronic supercharger, a motor and the second heat dissipation channel are sequentially connected in series to form a motor cooling loop so as to cool the electronic supercharger and the motor. According to the 48V hybrid electric vehicle thermal management system, the number of radiators can be reduced, the cost and energy consumption can also be reduced, the structure of the thermal management system can be simplified, spatial arrangement is more flexible, and meanwhile the working performance of the 48Vpower battery, the electronic supercharger and the motor can be guaranteed.
本发明涉及混合动力汽车技术领域,公开一种48V混合动力汽车热管理系统及混合动力汽车。本发明提供的48V混合动力汽车热管理系统,通过在散热器内设置相互独立的第一散热通道和第二散热通道,并使第一泵体、48V动力电池和第一散热通道依次串联组成低温冷却回路,以在48V动力电池对冷却需求不高时对48V动力电池进行冷却,同时使第二泵体、电子增压器、电机和第二散热通道依次串联组成电机冷却回路,以对电子增压器和电机进行冷却。本发明提供的48V混合动力汽车热管理系统,不仅能够减少散热器的使用数量,降低成本和能耗,而且可以简化热管理系统的结构,使空间布置更为灵活,同时能够保证48V动力电池、电子增压器和电机的工作性能。
