Abstract

The invention discloses a control method and device for a thermal management system of a vehicle and the vehicle, and relates to the field of vehicles. When a VCU cools a battery pack, the opening degree of a proportional valve in a heat exchange pipeline corresponding to the battery module can be controlled based on the detected temperature of each battery module and the detected temperature of the water inlet, so that balanced heat exchange of the battery modules releasing different heat can be realized, the cooling effect of the battery pack is effectively ensured, and the cooling efficiency of the battery pack is improved.

Description

technical field [0001] The present application relates to the field of vehicles, in particular to a control method and device for a thermal management system of a vehicle, and a vehicle. Background technique [0002] The thermal management system of the vehicle may include: a water pump, cooling components, a heat exchange pipeline, a circulation pipeline, and a battery management system (Battery Management System, BMS) connected to the battery pack. cool down. Wherein, the battery pack is socketed on the heat exchange pipeline. The first end of the circulation pipeline communicates with the first end of the heat exchange pipeline, the second end of the circulation pipeline communicates with the second end of the heat exchange pipeline, and both the cooling assembly and the water pump are connected with the circulation pipeline. The BMS is used to detect the temperature of the battery pack. [0003] In related technologies, the vehicle controller (Vehicle Controller Unit,...
