Design and test on battery thermal management system for new energy vehicles based on refrigerant direct cooling
In order to resolve the complex framework and high cost of current battery thermal management system of new energy vehicles,a battery thermal management solu-tion based on refrigerant direct cooling is proposed,and the thermal homogeneity of bat-tery under four kinds of heating power is tested and analyzed.The cooling performance comparison test is also conducted between liquid cooling plate and refrigerant direct cooling plate.The results show that under four kinds of heating power,the temperature differ-ences of battery surface are all less than 5℃ using refrigerant direct cooling plate.Compared with the liquid cooling plate,the refrigerant direct cooling plate can realize faster cooling rate and lower battery temperature in the center.The research results have certain refer-ence value for the thermal management technology study on new energy vehicles.
