The invention discloses a battery pack, an electric vehicle and an energy storage device, the battery pack comprises: a box body, the box body comprises a lower box body and an upper box cover covering the lower box body, and the lower box body forms an accommodating cavity; a plurality of single batteries which are arranged in the accommodating cavity side by side; busbars which are electricallyconnected between the single batteries and are arranged on the two sides of the single batteries in the arrangement direction of the single batteries; a battery management system which is fixedly connected to the lower box body; and a wiring harness which is electrically connected with the plurality of single batteries and the battery management system, wherein the wiring direction of the wiring harness is the same as the arrangement direction of the busbars, the wiring harness is arranged between the lower box body and the upper box cover side by side, the upper box cover is recessed in the direction far away from the lower box body to form a limiting groove for providing an avoidance space for the busbar and the wire harness, and the limiting groove is arranged in the length direction ofthe busbar and the wire harness. By arranging the limiting grooves, avoiding space is provided for the wire harness and the busbar, and the safety and strength of the battery pack are improved.

    本发明公开了一种电池包、电动汽车及储能装置,电池包包括:箱体,箱体包括下箱体以及盖设于下箱体上的上箱盖,下箱体形成容置腔;多个单体电池,各单体电池并排设置于容置腔内;汇流排,汇流排电连接于各单体电池之间,并于各单体电池排布方向设置于各单体电池的两侧;电池管理系统,电池管理系统固定连接于下箱体;以及线束,线束电连接多个单体电池和电池管理系统,且线束的走线方向和汇流排的排布方向相同且并排设置于下箱体与上箱盖之间;其中,上箱盖沿远离下箱体的方向凹陷形成为汇流排和线束提供避让空间的限位槽,限位槽沿汇流排和线束的长度方向设置。本发明通过设置限位槽,为线束和汇流排提供避让空间,提高了电池包的安全性和强度。
