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.
