Publication number: 20230187760Abstract: A battery module comprises a fixing component including a plurality of insertion posts, the insertion posts being sandwiched between a plurality of the cells. Further, the cell is provided with a fillet structure on the edges and the insertion post is connected to the fillet structure. According to the battery module, a plurality of removable reinforcement points are provided by a plurality of insertion posts, which do not affect the stacking density of the cells in the battery pack, and increasing the mechanical connection strength of the battery module. The removable design of the battery module and insertion posts solves the maintenance problem of the integrated battery pack and improves the safety of the battery module, featuring high structural strength, integrity and stability. A battery pack can include the battery module and an electric vehicle can include the battery pack.Type: ApplicationFiled: February 3, 2023Publication date: June 15, 2023Inventors: Hui CAO, Kai CAO, Yingqi CHEN, Wei LIU, Dandan CHEN, Xiaofeng YANG, Min HOU, Xianfeng YU, Chan LIU, Zhaoyu YU
