Abstract

The invention provides a power battery cooling system for an electric vehicle and a cooling method of the power battery cooling system. The power battery cooling system comprises a power battery box body, an evaporator, an air conditioning compressor and a condenser, wherein the evaporator is arranged in the power battery box body, the power battery box body is provided with a power battery air inlet, the power battery air inlet is communicated with a cabin of the electric vehicle and is connected with the air conditioning compressor by virtue of an air conditioning pipeline, and the air conditioning compressor is further connected with the condenser by virtue of the air conditioning pipeline. With the adoption of the power battery cooling system, different cooling modes are adopted according to different environmental temperatures, and thus the power battery cooling system is effectively cooled.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a power battery cooling system for electric vehicles and a cooling method thereof. Background technique [0002] As energy and environmental issues become the focus of attention on a global scale, electric vehicles with drive motors and power batteries instead of traditional internal combustion engines, and power batteries as power sources, will become one of the important development directions of the automotive industry in the future due to their advantages in environmental protection and energy saving. one. [0003] The power battery system is a high-voltage component that provides the power source for the vehicle by combining hundreds of battery cells in series and parallel. The safety and reliability of the high-voltage system is the first requirement to ensure the performance of electric vehicles. At present, most of the power batteries used in electric vehicle...
