Detection Method of New Energy Vehicle Thermal Management System Test Bench

In this paper, the detection method of the new energy vehicle thermal management system test bench has been studied in depth, respectively for the refrigeration charging condition, the system refrigeration condition, the system heating condition, the system dehumidification condition and the system defrosting condition, set their respective parameter conditions, and developed a corresponding detection scheme. The test results show that the developed testing method can accurately measure the temperature, pressure and flow parameters at key positions. The independent repeated measurements on the testing machine are carried out. The results indicate that the experimental standard deviation of the cooling capacity is 12.72W.
