AB - To meet the requirements of integrated testing and performance calibration for the early development of electric vehicle thermal management, this paper conducted research on the configuration scheme design of the electric vehicle thermal management integrated testing platform and simulation and optimization of the air supply system flow field. Firstly, a requirement analysis of the testing environment and the overall design of the testing platform was performed. Secondly, simulation techniques were applied to optimize the uniformity of the intake air-flow field in the test section, which was then validated through real testing. Finally, a comparative study of the tested system was conducted through CFD simulations in two different environments, the testing platform and the actual vehicle underhood. The results indicate that the intake air-flow field uniformity in the test section falls within ±3%. The intake flow rate errors for the radiator and condenser, compared to those in the actual vehicle, were found to be 0.039% and 2.116%, respectively. These findings confirm that the testing platform offers good consistency with the flow field in real vehicle testing scenarios.
