Abstract

The invention relates to a battery pack and an electric vehicle. The battery pack comprises the following components of: a plurality of battery cells which are stacked in the thickness direction of the battery cells to form a battery cell group; a box body enclosure frame which is integrally formed and is provided with an opening; a fixing plate matched with the opening; and a bottom plate matched with the box body enclosure frame. The bottom plate is fixed below the box body enclosure frame, the fixing plate is fixed at the opening, and the bottom plate, the fixing plate and the box body enclosure frame form a cavity for accommodating the battery cell group. According to the battery pack, related structural features of a battery module in a traditional battery pack are omitted, battery cells are directly put into the battery pack, and the size of the battery pack is greatly reduced.

Description

technical field [0001] The present disclosure relates to the field of electric vehicle manufacturing, and in particular, to a battery pack and an electric vehicle. Background technique [0002] The research and development of electric vehicles is mainly divided into three technical routes: pure electric, hybrid and plug-in hybrid. In the prior art, the production of battery packs for electric vehicles requires first stacking the cells, fixing them with end plates and side plates to form a battery module, and then putting them into the battery pack. Due to the small volume of the battery pack required in the hybrid electric vehicle, the battery pack produced by the conventional technical solution is relatively large, and is not suitable for being placed in the hybrid electric vehicle. If the volume of the battery pack is forcibly reduced, it will have a greater impact on the energy density and grouping method of the battery pack, thereby limiting the performance of the elect...
