The invention provides a battery pack, a quick-change assembly and an electric vehicle, the battery pack comprises a battery pack body and a limiting structure, the limiting structure extends from the outer side surface of the battery pack body to the direction away from the battery pack body, in the height direction of the battery pack, at least part of orthographic projection of the limiting structure coincides with a matching part arranged on the electric vehicle, and the matching part is matched with the battery pack body. The limiting structure is arranged to abut against the matching part when the battery pack is installed on the electric vehicle so as to limit movement of the battery pack body in the height direction of the battery pack. When the battery pack is installed on the electric vehicle, in the height direction of the battery pack, the limiting structure abuts against the matching part on the electric vehicle, and the displacement of the battery pack body in the height direction of the battery pack is limited after abutting, so that the battery pack is prevented from shaking up and down relative to the electric vehicle, the stability of connection between the battery pack and the electric vehicle is guaranteed, and the service life of the battery pack is prolonged. And the safety and stability of the electric vehicle in the driving process are ensured.

    本发明提供一种电池包、快换总成和电动车辆,电池包包括电池包本体和限位结构,限位结构自电池包本体的外侧面朝远离电池包本体的方向延伸,在电池包的高度方向上,限位结构的至少部分正投影与电动车辆上设置的配合部重合,限位结构设置为当电池包安装于电动车辆,限位结构抵接于配合部,以限制电池包本体在电池包的高度方向上的移动。当电池包安装于电动车辆上,在电池包的高度方向上,限位结构将抵接于电动车辆上的配合部,抵接后电池包本体沿电池包高度方向上的位移将被限制,也就避免了电池包相对于电动车辆上下晃动,保证了电池包与电动车辆连接的平稳性,进而保证了电动车辆行驶过程的安全稳定性。
