Research on Battery Pack and Cabin Cooling for an Electric Vehicle
The temperature of the battery pack in electric vehicles directly affects the performance of the bat-tery pack,which in turn affects the thermal safety performance,power performance,and economy of the vehi-cle.The temperature control of the passenger compartment is related to the comfort of the entire vehicle.Usual-ly,the thermal management system of the battery pack and the passenger cabin air conditioning system are inte-grated together,which puts higher requirements on the design of the air conditioning system.In the article,a set of integrated thermal management system was designed for a certain EV model as the research object.The sys-tem requirements were decomposed by calculating the thermal load of the battery pack and air conditioning sys-tem,and then the cooling performance of the battery pack and passenger compartment was predicted through simulation analysis.Optimization was carried out for working conditions that did not meet the requirements.The results showed that the optimized solution could meet the cooling needs of the battery pack and passenger com-partment.
