The invention discloses a battery pack assembly and an electric vehicle, the battery pack assembly comprises a plurality of battery packs, the plurality of battery packs are used for being arranged along the length direction of the electric vehicle, and each battery pack is hung and independently locked at the bottom of a vehicle beam of the electric vehicle from bottom to top along the vertical direction; the multiple battery packs are arranged in the length direction of the electric vehicle, the mass of each battery pack is small while the electric quantity needed by the electric vehicle is guaranteed, the battery packs are replaced from the lower portion of the electric vehicle in the process of disassembling the battery packs from the electric vehicle, the gravity center of the electric vehicle is kept stable, and therefore inclination is not prone to occurring, and the service life of the electric vehicle is prolonged. And the locking efficiency of the battery pack is improved. The locking part is arranged on the side wall of the battery pack, so that an unlocking mechanism of the battery replacing equipment can be conveniently unlocked along a gap between the battery packs, connection and locking with the locking mechanism from bottom to top in the vertical direction are realized, the lifting process and the locking process of the single battery pack are combined, and the locking efficiency of the single battery pack is further improved.
本发明公开了一种电池包总成及电动车辆,电池包总成包括多个电池包,多个电池包用于沿电动车辆的长度方向排布,各电池包均沿竖直方向自下而上挂接并独立锁止于电动车辆的车梁底部,多个沿着电动车辆的长度方向排布的多个电池包,在保证电动车辆所需电量的同时使得每个电池包的质量较小,在将电池包装拆在电动车辆的过程中,从电动车辆的下方对电池包进行更换,电动车辆的重心保持稳定从而不易发生倾斜,电池包的锁止效率提高。通过电池包侧壁设置锁止部,便于换电设备的解锁机构沿着电池包之间的间隙进行解锁,实现沿竖直方向自下而上与锁止机构连接锁止,从而将单个电池包抬升过程与锁止过程相结合,进一步提高单个电池包的锁止效率。
