The invention discloses a battery pack assembly and an electric vehicle, the electric vehicle is provided with a longitudinal beam and a quick-change support, the battery pack assemblies are arranged on the two sides of the longitudinal beam in the width direction, and the quick-change support is used for bearing the battery pack assemblies in the gravity direction; and a lock mechanism is arranged at the bottom of the battery pack assembly and is locked with the quick-change bracket along the gravity direction. The top lifting height of the battery pack assembly is reduced, the gravity center of the battery pack assembly is reduced, and the stability of the battery pack assembly is improved; the battery pack assembly can be arranged and fixed on the two sides of the longitudinal beam through the quick-change support, the influence on the battery pack assembly is small when the electric vehicle is twisted in the running process, and the battery pack assembly is prevented from being damaged; the electric vehicle can be subjected to double-side battery replacement, the battery replacement efficiency is improved, and the influence of the size of the longitudinal beam on battery replacement is reduced; and through the bottom connection and locking mode, locking and unlocking, connection and disassembly of the battery pack assembly and the quick-change bracket are facilitated.

    本申请公开一种电池包组件及电动车辆,所述电动车辆设有纵梁和快换支架,所述纵梁的宽度方向的两侧均设有所述电池包组件,所述快换支架用于沿重力方向承载所述电池包组件;所述电池包组件的底部设有锁机构,所述锁机构与所述快换支架沿重力方向锁接。本申请降低了电池包组件的顶吊高度,降低了电池包组件的重心,增加电池包组件的稳定性;使得电池包组件能够通过快换支架在纵梁的两侧布置和固定,电动车辆在行驶过程中遇到扭转时对电池包组件的影响小,避免电池包组件损坏;使得电动车辆能够进行双侧换电,提高换电效率,且减小了纵梁尺寸对换电的影响;底部连接和锁接的方式,方便电池包组件与快换支架位置的加解锁、连接和拆卸。
