The embodiment of the invention provides a vehicle thermal management system for a commercial vehicle. The vehicle thermal management system is used for solving the technical problem that the temperature difference of battery cells in vehicle thermal management of an existing new energy commercial vehicle is too large. The system comprises a motor cooling loop, a battery heat management loop, a refrigerant loop, a cab heat management loop and a heat management controller. Wherein the motor cooling loop can be communicated with and cut off from the battery heat management loop, and the refrigerant loop is used for refrigeration of a battery system and a cab through heat exchange. The flow of each branch of battery thermal management can be dynamically distributed, the positive and reverse alternating flow of cooling liquid can be realized, the temperature difference of battery cells in a battery system is reduced, and the consistency of the battery cells is favorably improved.

    本申请实施例提供了一种商用车整车热管理系统,用以解决现有的新能源商用车整车热管理电芯温差过大的技术问题。系统包括电机冷却回路、电池热管理回路、制冷剂回路、驾驶室热管理回路以及热管理控制器;其中,所述电机冷却回路可与电池热管理回路进行连通和截止,所述制冷剂回路通过热交换用于电池系统和驾驶室的制冷。可动态分配电池热管理各支路流量,并可实现冷却液正向逆向交替流动,降低了电池系统中电芯的温差,有利于提高电芯一致性。
