Development of test equipment and measurement&control software for electric vehicle refrigerant compressor based on CAN communication
One test equipment and measurement&control software for electric vehicle refrigerant compressor is developed based on CAN communication.This system is classi-fied into two major categories:durability and performance test equipment with measure-ment&control system.The durability test equipment operates using the gas loop method,and the performance test equipment operates using the second refrigerant calo-rimeter method and the refrigerant liquid flow meter method.The test results show that compared with the manual control mode,the automatic control mode has significant im-provement in control accuracy and real-time performance of parameters such as compre-ssor speed,and the measurement accuracy of input power and cooling capacity are im-proved by 5.11%and 5.53%respectively.
