Abstract

A thermal management system heat management method and automobile, wherein the thermal management system comprises a motor cooling system and a battery thermal management system, Also includes three-way valve, Branch circuits and heat exchangers, The three-way valve is connected to a first coolant loop between the drive motor of the motor cooling system and the radiator, one end of the branch loopis connected to an outlet of the three-way valve, the branch loop is connected in parallel with the first coolant loop, and the branch loop and the second coolant loop of the battery thermal management system are connected in parallel with heat exchange through a heat exchanger. When the battery thermal management system heats the battery at a low temperature, the heat absorbed by the motor cooling system drives the motor to assist in heating the battery in the battery thermal management system, thereby reducing the battery heating power consumption in the battery thermal management system.

Description

technical field [0001] The present invention relates to the technical field of new energy vehicles, in particular to a thermal management system, and also to a thermal management method based on the thermal management system and a vehicle including the thermal management system. Background technique [0002] At present, new energy vehicles on the market mainly include hybrid vehicles and pure electric vehicles. The electric drive system of new energy vehicles mainly includes drive motors and batteries. The electric drive system generates heat during work. The motor is cooled, and the battery is thermally managed by the battery thermal management system. [0003] Among them, the existing motor cooling system uses water pumps, radiators, electronic fans, and temperature sensors to form a series independent loop with the drive motor, motor controller, and generator for temperature control. The coolant in the loop absorbs the temperature of the drive motor. After the heat is re...
