Problems solved by technology

However, when the thermal management system of the battery system heats the battery in a low-temperature environment, if it is heated from a lower temperature to an appropriate battery temperature, it will take a lot of heating time due to the large temperature difference and will consume too much heat.

Abstract

The invention discloses a vehicle thermal management method, device and system. According to the scheme, the method comprises the steps: detecting the external environment temperature of a vehicle; when the external environment temperature is lower than a first preset value, detecting the water inlet temperature of a cooling water circulation loop of the vehicle electric drive thermal management system; controlling the circulation direction of cooling water in a cooling water circulation loop and the circulation direction of heating water in a heating water circulation loop of the vehicle battery heat management system based on the water inlet temperature; and heating a vehicle battery located on the heated water circulation loop based on the cooling water and the heated water. The cooling water waste heat of the vehicle battery heat management system can be effectively utilized to heat the vehicle battery, the battery energy consumption is reduced, and the vehicle heat management efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of vehicle thermal management, in particular to a vehicle thermal management method, device, and system. Background technique [0002] High With the improvement of environmental quality and the improvement of the national carbon emission credit system, electric vehicles have become the transformation strategy of major car companies, and the competition in the field of electric vehicles has also intensified. Thermal management is the temperature control safety of electric vehicle batteries and electric drive motor systems. important areas of reliability, [0003] At present, the common thermal management method of the electric drive system of electric vehicles is to use the conventional water-cooled radiator cooling system, calculate the performance requirements of the radiator according to the different working conditions of the motor, configure the corresponding water pump, and calibrate the contr...
