The invention discloses a commercial vehicle thermal management system and method, belongs to the field of vehicle thermal management systems, and aims to solve the problems that the thermal management of a whole vehicle cannot be coordinated, the efficiency is relatively low, the system is relatively complicated, the occupied vehicle use space is relatively large, PTC (Positive Temperature Coefficient) is generally adopted for direct heating, the mode is non-uniform in heating, and the local temperature is relatively high due to the existing air conditioning system. Comprising a driving system cooling subsystem, a cockpit heating subsystem, a battery heating subsystem, a cockpit refrigerating subsystem and a battery cooling subsystem. Driving system cooling, cockpit cooling, cockpit heat supply, battery cooling and battery heat supply are effectively combined through a CHILLER (battery heat exchanger), a cooler which is independently adopted is omitted, meanwhile, positive influences are generated on pipeline arrangement and front cabin arrangement, the heat management efficiency of the whole vehicle is improved, and the available space of the whole vehicle is enlarged. The external PTC is used for heating the circulating water path, and the water path is uniformly distributed in the battery, so that the heating is more uniform, and the heat efficiency is higher.

    一种商用车热管理系统及方法,属于汽车热管理系统领域,是针对现有空调系统造成整车热管理无法协同,效率较低,同时系统较复杂,占用车辆使用空间较大,通常采用PTC直接加热,该方式加热不均匀,且存在局部温度较高的问题所提出。包括驱动系统冷却子系统、驾驶舱制热子系统、电池加热子系统、驾驶舱制冷子系统、电池冷却子系统。利用CHILLER(电池热交换器)将驱动系统冷却、驾驶舱冷却、驾驶舱供热、电池冷却及电池供热有效的结合起来,节省了单独采用的冷却器,同时对管路布置和前机舱布置产生了积极的影响,提升了整车的热管理效率,提高整车的可利用空间。利用外置PTC对循环水路进行加热,水路均布电池内,使受热更均匀,热效率更高。
