The invention provides a battery pack and an electric vehicle, the battery pack is detachably mounted on the electric vehicle, in the height direction of the electric vehicle, the battery pack comprises a plurality of stacked battery bodies; wherein the perimeters of the at least two battery bodies are different in the direction perpendicular to the height direction of the electric vehicle. The battery bodies are stacked in the height direction of the electric vehicle, and the perimeters of the at least two battery bodies are different, that is, the outer side surface of the battery pack in the height direction of the electric vehicle is not flush up and down, and at least the outer side surface of the battery pack is provided with a concave area at the position of the battery body with the shorter perimeter. When the battery pack is installed on the electric vehicle, the concave area can avoid a corresponding component structure on the electric vehicle, interference with the electric vehicle is avoided, and other battery bodies can be kept large in size, so that the capacity of the battery pack is improved.
本发明提供一种电池包及电动车辆,所述电池包可拆卸地安装于电动车辆上,在所述电动车辆的高度方向上,所述电池包包括多个叠设的电池本体;其中,在垂直于所述电动车辆的高度方向上,至少两个所述电池本体的周长不同。电池本体在电动车辆高度方向上叠设,且至少两个电池本体的周长不同,即,电池包在电动车辆高度方向上的外侧面不是上下齐平的,至少在周长较短的电池本体处,电池包的外侧面有凹陷区域。当电池包安装在电动车辆上时,凹陷区域可以避让电动车辆上相应的部件结构,避免和电动车辆发生干涉,而其他的电池本体可以保持较大尺寸,以提高电池包的容量。
