A stable and efficient cooling and heat dissipation system of lithium battery pack is very important for electric vehicles. The temperature uniformity design of the battery packs has become essential. In this paper, an optimization design framework is proposed to minimize the maximum temperature difference (MTD) of automotive lithium battery pack. Firstly, the cooling channels of two cooling and heat dissipation structures are analyzed: serpentine cooling channel and U-shaped cooling channel. The results show that the serpentine cooling channel has better cooling effect. Secondly, the adaptive ensemble of surrogate models based on an improved particle swarm optimization algorithm is proposed to aid the optimization design of the serpentine cooling channel. The results show that the maximum temperature difference of the optimized scheme is reduced by 7.49% compared with the initial scheme, and the temperature field distribution of the lithium battery pack is more uniform. The proposed optimization design framework has certain guiding significance for the liquid cooling design of the battery packs.
