摘要：
Aiming at the requirements of highest temperature and temperature evenness on lithium-ion battery pack at different charging rates, the thermal model for traction battery is constructed and a simulation is conducted with suppressing the highest temperature and maximum temperature difference as objectives to analyze the effects of the arrangement of liquid cooling plates, flow path design and the position of cooling inlet and outlet on the thermal status of battery pack. The results of simulation show that with the cooling system designed, the highest temperature and maximum temperature difference of battery pack can be controlled at below 35.5 ℃ and 5 ℃ respectively at a charging rate of 2C. © 2022, Society of Automotive Engineers of China.
