Abstract

The invention provides an electric vehicle motor battery cooling and heat pump cooling circulation system and an operation method. The electric vehicle motor battery cooling and heat pump cooling circulation system comprises a heat transfer fluid loop in which heat transfer fluid flows, the heat transfer fluid loop comprises a first heat exchanger, a motor electric control unit, a main motor unit, an auxiliary motor unit, a motor water pump, a cooling liquid three-way valve, a cooling liquid stop valve, a first double-fluid heat exchanger, a battery water pump, a battery cooling device, a cooling liquid one-way valve, a cab water pump, a second double-fluid heat exchanger, a water heater and a cooling liquid three-way proportional valve. A second heat exchanger and a third heat exchanger. The battery loop, the motor loop and the air conditioner loop are used as a whole for thermal management through the heat transfer fluid loop, unified integrated management can be achieved, the number of parts can be reduced, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a cooling cycle system and an operation method for cooling a motor battery of an electric vehicle and a heat pump. Background technique [0002] A complete pure electric vehicle thermal management system should comprehensively integrate three major thermal management systems including the thermal management of the vehicle environment, the thermal management of the power battery, and the thermal management of the drive motor. [0003] At present, the existing cooling, heating, battery and motor thermal management of pure electric vehicles are relatively independent and scattered, which cannot be effectively unified and integrated management, and the cost is high. Contents of the invention [0004] The embodiment of the present invention provides a cooling cycle system and operation method for electric vehicle motor battery cooling and heat pump to solve the problem tha...
