The invention relates to a battery module, a battery pack and a vehicle. The battery module comprises a battery cell stack and an end plate, and the battery cell stack comprises a plurality of battery cells arranged in an array; the end plates are respectively arranged at two ends of the cell stack; wherein an expansion cavity is formed in one side, close to the battery cell pile, of the end plate and is used for providing an expansion space for the battery cell. According to the scheme provided by the invention, a module side plate does not need to be arranged, the volume energy density of the battery cell is improved, and the endurance mileage of the electric automobile is improved; and the end plates at the two ends of the battery module are provided with the expansion cavities, so that the overall weight is reduced, an expansion space is provided for expansion of the battery cells, and the cycle life of the battery cells is prolonged.

    本申请涉及一种电池模组、电池包及车辆。该电池模组包括电芯堆和端板,其中,电芯堆包括阵列排布的多个电芯;端板分别设置于电芯堆的两端;其中:端板靠近电芯堆的一侧开设有膨胀腔,膨胀腔用于为电芯提供膨胀空间。本申请提供的方案,无需再设置模组侧板,提高电芯的体积能量密度,提高电动汽车的续航里程;并将电池模组两端的端板开设膨胀腔,降低整体重量的同时,为电芯的膨胀提供膨胀空间,提高电芯的循环寿命。
