Abstract

The invention discloses a control method of an automobile comprehensive thermal management system. The control method comprises the following steps that a comprehensive thermal management controller acquires the temperature of cooling liquid in a motor cooling loop and the average temperature of a power battery; if the temperature of the cooling liquid in the motor cooling loop reaches the high temperature of a motor or the average temperature of the power battery reaches the high temperature of the battery, the refrigeration mode is started, the motor cooling loop is neutralized or the cooling liquid in the battery cooling loop is cooled until the temperature of the cooling liquid in the motor cooling loop is lower than the cooling cut-off limit value of the motor, and the average temperature of the power battery is lower than the cooling cut-off limit value of the battery; and if the average temperature of the power battery is lower than the low temperature of the battery, the heating mode is started, the cooling liquid in the battery heating loop is heated by utilizing the heat generated in the automobile comprehensive thermal management system until the average temperature of the power battery is higher than the heating cut-off limit value of the battery, 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 ...
