Abstract

The invention provides an integrated type heat management system for a hybrid power car and a control method thereof. The system comprises an engine heat dissipater, an air-conditioner for the car, acondenser, an evaporator, a power battery, a drive motor, a motor controller, a motor heat dissipater, a four-way reversing valve and a three-way reversing valve. According to the control method, temperature values T1, T2, T3 and T4 are set, wherein T1 is smaller than T2, T2 is smaller than T3, and T3 is smaller than T4; when the environment temperature is below T1, if the temperature of the powerbattery is smaller than T1, a heater heats the power battery; when the temperature of the power battery surpasses T1, battery cooling liquid heats the power battery; when the temperature of the powerstorage surpasses T4, the motor heat dissipater dissipates the heat; and when the environment temperature is over T1, the drive motor utilizes the motor heat dissipater for dissipating the heat, andthe power battery utilizes a refrigerating device for dissipating the heat. The drive motor, a power battery temperature controlling system, the air-conditioner for the car and the engine heat management system are controlled in an integrated manner, all the systems coordinate mutually, and the energy consumption of the whole car is reduced.

Description

technical field [0001] The invention relates to an automobile heat management system, more specifically to an integrated heat management system of a hybrid electric vehicle and a control method thereof, and belongs to the technical field of automobile heat management systems. Background technique [0002] At present, most hybrid electric vehicle motors and battery thermal management systems are independent of each other. The motor is basically cooled by liquid cooling. The motor radiator is used to dissipate heat from the coolant, and the cooled coolant dissipates heat to the drive motor and motor controller. The cooling of the power battery adopts two methods: forced air cooling and liquid cooling. The forced air cooling uses the cold air inside the vehicle body to dissipate heat from the power battery, but the cooling effect of this method is poor; Heat exchange for heat dissipation and cooling. Moreover, the separation of battery temperature control and motor temperature...
