摘要
研制基于CAN通信的电动汽车用制冷剂压缩机试验装置及其测控软件,该套系统分为耐久性试验装置测控系统和性能试验装置测控系统,耐久试验装置采用气环法测试,性能试验装置采用第二制冷剂量热器法和制冷剂液体流量计法测试.测试结果表明,与手动控制相比,自动控制能够提高压缩机转速等参数的控制精度和实时性,输入功率和制冷量的测量准确度分别提升 5.11%和 5.53%.
Abstract
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.
