A control method for an automotive integrated thermal management system, comprising the following steps: the integrated thermal management controller obtains the temperature of the coolant in the motor cooling circuit and the average temperature of the power battery; if the temperature of the coolant in the motor cooling circuit reaches the high temperature of the motor , or the average temperature of the power battery reaches the high temperature of the battery, the cooling mode is turned on to cool the coolant in the motor cooling circuit and / or the battery cooling circuit until the temperature of the coolant in the motor cooling circuit is lower than the motor cooling cut-off limit value, and the average temperature of the power battery is lower than the battery cooling cut-off limit; if the average temperature of the power battery is lower than the low temperature of the battery, the heating mode is turned on, and the heat generated in the vehicle's integrated thermal management system is used to cool the battery heating circuit. The liquid is heated until the average temperature of the power battery is greater than the battery heating cut-off limit, and then the shutdown mode is executed.
Description
technical field [0001] The invention relates to the field of new energy technologies, in particular to a control method for an automobile comprehensive thermal management system. Background technique [0002] Thermal management technology is one of the core technologies of pure electric vehicles. Its function is to keep components such as drive motors and power batteries within an appropriate temperature range under all working conditions. The thermal management system of a pure electric vehicle usually includes a motor cooling system and a battery thermal management system. The motor cooling system is responsible for cooling the driving motor or the motor controller and other components when the temperature is high. When the temperature of the power battery is heated, it is cooled when the temperature of the power battery is high. Although the existing thermal management system can effectively control and manage the temperature of components such as drive motors and power ...
