According to the driving conditions and design requirements of electric vehicles, this paper pro-poses a matching design scheme suitable for electric vehicle heat pump air conditioning systems, which mainly includes the calculation of automobile hot (cold) load and matching methods of main parameters of main components. An electric vehicle heat pump air-conditioning system was used to verify the reliability of the method, simulate the design conditions in the environmental simulation laboratory, conduct experimental tests on the performance of the designed heat pump, and compare and analyze with the design goals. The results show that the experimental results are basically consistent with the design goals, and the error is within 5%. It can be seen that the matching design method of the electric vehicle heat pump air conditioning system proposed in this paper combines the driving state and working environment of the car, which is suitable for the basic electric vehicle heat pump air conditioning system to provide a reliable method and ideas for the design of heat pump air conditioning systems for electric vehicles.
