Effective battery thermal management is crucial to the design of high performance and durable batteries for electric vehicles. In order to reduce the flow resistance of the traditional straight linear flow channel, the author proposed a divergent-shaped channel. In this paper, a battery thermal management model was established for the design of divergent flow channel by numerical simulation method. The momentum, mass and energy conservation equations of the coolant and the energy conservation equations of the cold plate and the battery were considered. In this work, the influence of the sub-channel outlet width on pressure drop and temperature difference is investigated. When the sub-channel outlet width increases from 3mm to 6mm, the pressure drop reduced by 41.76%, at the same time the battery temperature differential also decreased by 17%. In addition, it is found that the optimal sub-channel outlet width is 10 mm. In order to improve the performance of the divergent-shaped channel, a partition divergent-shaped channel design is proposed, and the effects of inlet vertical channel width Wfd and outlet vertical channel width Wbd are studied. Compared with Wbd, The effect of Wfd was more significant. With the increase of Wfd, both pressure drop and temperature difference decrease gradually. The research in this paper will contribute to the development of more efficient and energy saving battery thermal management system.
