Abstract

The invention discloses a distributed type hub motor electric vehicle heat management system and a method. The heat management system comprises a first cooler, a first water pump, a second water pump,a second cooler, a third water pump, a change-over valve, a controller, a motor temperature sensor for monitoring the temperature of a motor stator, a motor controller temperature sensor for monitoring the temperature of a motor controller, and a battery temperature sensor for monitoring the temperature of a battery. The water outlet end and the water inlet end of the first cooler are connected with the water inlet end and the water outlet end of the first water pump respectively. The first cooler, the first water pump, the second water pump, the motor and a water sleeve of the motor controller form a first cooling pipeline. The water outlet end and the water inlet end of the second cooler are connected with the water inlet end of the third water pump and a battery water sleeve respectively. The battery water sleeve is connected with the water inlet end of the second cooler. The second cooler, the third water pump and the battery water sleeve form a second cooling pipeline. The change-over valve is connected with the first cooling pipeline and the second cooling pipeline. The controller controls the on and off of the three water pumps and the change-over valve. The energy utilization rate is increased.

Description

technical field [0001] The invention belongs to the field of thermal management of electric vehicles, in particular to a thermal management system and a control method of a distributed in-wheel motor electric vehicle. Background technique [0002] The automotive thermal management system is mainly used to dissipate heat from the heating elements of the automobile, ensuring that the heating elements can work normally within a suitable temperature range under any working conditions. The heat dissipation system of electric vehicles usually uses cooling water as the cooling medium, and the heat dissipation system is generally composed of water pumps, radiators, cooling fans, thermostats and other auxiliary devices. The working efficiency of the vehicle thermal management system will directly affect the working status of the automobile motor, motor controller, power battery, etc. Nowadays, electric vehicles driven by distributed in-wheel motors are generally inefficient in the t...
