The invention provides a battery pack assembly, a battery pack module and an electric vehicle. The battery pack assembly comprises a battery and two connecting end plates, wherein the connecting end plates are respectively arranged at two sides of the battery, each connecting end plate comprises an end plate body and two connecting columns connected to a group of opposite sides of the end plate body respectively, the interior of the connecting column is divided into a first space and a second space by a threaded connection shoulder in the extending direction of the connecting column, a fixingsleeve and a screw rod assembly are arranged in each connecting column, the fixing sleeve is arranged at the opening, deviating from the second space, of the first space, an inward-contracting bayonetis formed in the end, exposed out of the surface of the connecting column, of the fixing sleeve, the first end of the screw rod assembly is in threaded connection with the threaded connection shoulder, the second end of the screw rod assembly penetrates through the second space to be exposed out of the connecting column, the outer diameter of the second end of the screw rod assembly is matched with the inner diameter of the inward-contracting bayonet, and the extending directions of the connecting columns of all the connecting end plates are parallel to one another. According to the invention, stacking is convenient to achieve, disassembly and assembly are rapid, and the battery replacement speed is increased.
本发明提供了电池包组件、电池包模组以及电动车,该电池包组件包括:一电池和两连接端板,连接端板分别设置于电池的两侧,每个连接端板包括:一端板本体;两连接柱,分别连接于端板本体的一组对边,连接柱内部被螺接肩台沿连接柱的延展方向分割为第一空间和第二空间;每个连接柱内分别设置一固定套和一螺杆组件,固定套设置于第一空间背离第二空间的开口处,固定套露出于连接柱表面的一端设有内缩卡口;螺杆组件的第一端螺接于螺接肩台,螺杆组件的第二端穿过第二空间露出于连接柱之外,螺杆组件的第二端的外径与内缩卡口的内径相配合,所有连接端板的各连接柱的延展方向相互平行。本发明便于实现堆叠,拆装快捷,加快了更换电池的速度。
