In view of the poor cooling effect on a lithium-ion battery module (LIBM) when using one single cooling method, a phase change material (PCM)-air cooling coupled battery cooling system was proposed. First, the influences of different inlet air velocities (IAVs), battery gaps (BGs) and inlet air temperatures (IATs) on the highest temperature and maximum temperature difference of LIBM were discussed. Second, with the IAV, BG and IAT as design variables and the highest temperature and maximum temperature difference as objective functions, the design variables and objective functions were numerically fitted by a response surface model. Third, the non-dominated sorting genetic algorithm-II is used to optimize and predict the response surface model. Finally, the optimization and prediction results were verified by simulations based on computational fluid dynamics. Results show that the optimized cooling system can reduce the highest temperature in LIBM by 4.68 ℃ (13.8%) and the maximum temperature difference by 0.57 ℃(30.3%).
