The quick-change battery pack is detachably arranged on a longitudinal beam of the electric vehicle, a groove is formed in the top of the quick-change battery pack, the quick-change battery pack comprises a battery pack box body and a battery cell, a plurality of lock connecting structures are arranged on the battery pack box body, the lock connecting structures are all located in the groove, and the battery cell is located in the groove. A plurality of battery cell accommodating cavities for placing battery cells are formed in the battery pack box body, at least part of the battery cell accommodating cavities are distributed on the two sides of the groove, and the battery pack box body is connected to the longitudinal beam through a plurality of lock connecting structures. The gravity center of the quick-change battery pack is located below the longitudinal beam, the gravity center of the battery pack can be effectively lowered, the stability of the battery pack is improved, and the stability and safety of a vehicle are improved by a large space. The spaces on the two sides of the longitudinal beam are utilized to store and accommodate more battery cells, so that the travel distance of the electric vehicle is farther, and the replacement frequency of the electric vehicle is reduced; and the structure is compact, and the space utilization rate is high, especially the space in the vertical direction.

    本发明公开了一种快换电池包及包含其的电动汽车,快换电池包可拆卸地设置在电动汽车的纵梁上,快换电池包顶部设有凹槽,快换电池包包括电池包箱体与电芯,电池包箱体上设有若干个锁连接结构,若干个锁连接结构均位于凹槽内,电池包箱体内设有若干个用于放置电芯的电芯容纳腔,至少部分电芯容纳腔分布于凹槽的两侧,电池包箱体通过若干个锁连接结构连接于纵梁。实现快换电池包的重心处于纵梁的下方,能够有效降低电池包的重心,增加电池包的稳定性,对车辆平稳性、安全性提升一个较大空间。使得对纵梁两侧的空间利用来存放容纳更多的电芯,实现电动汽车行程更远,减少电动汽车的更换次数;且结构紧凑,空间利用率高,尤其是竖直方向上的空间。
