The invention discloses a quick-change battery pack, an electric automobile and a battery changing method of the electric automobile, the quick-change battery pack is detachably arranged on a longitudinal beam of the electric automobile, a groove is formed in the bottom of the quick-change battery pack, the quick-change battery pack comprises a battery pack box body and battery cells, a plurality of battery cell containing cavities used for containing the battery cells are formed in the battery pack box body, and the battery cells are arranged in the battery pack box body. At least part of the battery cell containing cavities are distributed on the two sides of the groove, the battery pack box body is provided with a plurality of lock connecting structures, the lock connecting structures are all located in the groove, and the battery pack box body is connected to the longitudinal beam through the lock connecting structures. The electric automobile comprises two longitudinal beams, a plurality of locking mechanisms and a quick-change battery pack. The gravity center of the quick-change battery pack is 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 beams are utilized to store and accommodate more battery cells, so that the travel distance of the electric automobile is farther, and the replacement frequency of the electric automobile is reduced; the structure is compact and the space utilization rate is high.

    本发明公开了一种快换电池包、电动汽车和电动汽车的换电方法,快换电池包可拆卸地设置在电动汽车的纵梁上,快换电池包的底部设有凹槽,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,电池包箱体通过若干个锁连接结构连接于纵梁。电动汽车包括两个纵梁、若干个锁止机构和快换电池包。有效降低快换电池包的重心,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。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。
