[0002] With the rapid development of electric vehicles, battery swapping at stations has become an efficient and convenient way to replenish power. As battery swapping stations develop rapidly, the number of batteries they can accommodate is constantly increasing, and their electrical efficiency is also continuously improving. However, this also leads to a continuous increase in the heat generated by the batteries during charging. Furthermore, the increased battery capacity also results in increased heat generation. Since battery swapping stations are typically located outdoors, they are greatly affected by the environment, especially in summer and winter. Therefore, appropriate thermal management devices are needed to control the temperature of the battery swapping stations.
