Problems solved by technology

[0003] Since pure electric vehicles use power batteries as energy sources, the current power battery components are mainly lithium iron phosphate or ternary materials. During the charging and discharging process, especially when charging and discharging with high current, the battery itself will generate temperature rise, which will affect battery performance
At present, battery thermal management at home and abroad is mostly realized b

Abstract

The invention discloses a double-evaporator air-conditioning system for a pure electric vehicle and a control method of the system. The system comprises a first pipeline, a second pipeline, a third pipeline, a compressor, a condenser, a liquid storage device, a first solenoid valve, a battery evaporator assembly, a second solenoid valve, an air-conditioning evaporator assembly and an air-conditioning controller, wherein one end of the first pipeline is connected with an outlet of the compressor, and the other end of the first pipeline is connected with an inlet of the liquid storage device through the condenser; one end of the second pipeline is connected with an outlet of the liquid storage device, and the other end of the second pipeline is connected with an inlet of the compressor through the first solenoid valve and the battery evaporator assembly sequentially; one end of the third pipeline is connected with an inlet of the liquid storage device, and the other end of the third pipeline is connected with the inlet of the compressor through the second solenoid valve and the air-conditioning evaporator assembly sequentially; the air-conditioning controller is electrically connected with the compressor, the first solenoid valve and the second solenoid valve respectively. According to the air-conditioning system, passenger compartments and battery compartments can be simultaneously refrigerated and cooled, and high comfort level of the passenger compartments and battery heat management can be realized.

Description

technical field [0001] The invention relates to the technical field of automobile air-conditioning, in particular to a dual-evaporator air-conditioning system for a pure electric vehicle and a control method thereof. Background technique [0002] With the continuous consumption of energy and the increasingly severe greenhouse effect, many automobile companies around the world are investing more energy in the research and development of electric vehicles. Pure electric vehicle technology is considered to be one of the important trends in the development of electric vehicles in the future. [0003] Since pure electric vehicles use power batteries as energy sources, the current power battery components are mainly lithium iron phosphate or ternary materials. During the charging and discharging process, especially when charging and discharging with high current, the battery itself will generate temperature rise, which will affect battery performance. At present, battery thermal ...
