GT-POWER and Simulink software are used to explore the influence of factors such as external temperature and radiator layout on the battery thermal management system, and prepare for the subsequent exploration of the joint simulation of the battery thermal management system under low temperature radiator threshold control and fuzzy control. The cooling and energy-saving effects of the fan and compressor using fuzzy control are analyzed. The results show that cooling the power battery with refrigerant is not affected by the external temperature. Under the condition of good temperature consistency of battery pack, compared with the threshold control, the fuzzy control strategy for fan and compressor speed can save about 23.1% and 14% of energy consumption respectively, which helps to improve the driving range of the vehicle.
