Abstract

The invention discloses a battery pack. A first battery and a second battery are arranged, a miniature end plate is arranged between the first battery and a side plate, and meanwhile, the miniature end plate or the end plate is detachably connected with a bottom plate of a box body, so that when a battery module is taken out of the battery pack, the battery module can be disassembled from the battery pack in a lossless manner only by disassembling the connection between the miniature end plate and the bottom plate or the connection between the end plate and the bottom plate, so that the lossless disassembly is realized, the disassembly and assembly efficiency is effectively improved, and the damage caused in the disassembly and assembly process is avoided; meanwhile, the connection strength between the battery module and the box body can be improved, and the reliability of the battery pack is effectively improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack. Background technique [0002] At present, the technological development trend of the power battery industry is developing towards higher and higher energy density. For battery pack products, it can include "large modules (that is, battery modules including more batteries)", making Place as many batteries as possible in the limited space of the battery pack to maximize the overall energy density of the battery pack. [0003] Among them, the "big module" has a large weight and a large volume. In order to firmly install the "big module" in the battery pack, the end plate in the "big module" can usually be connected to the box body of the battery pack. It is connected by bolts, and at the same time, the bottom of the "big module" is bonded to the bottom plate of the box with thermally conductive structural adhesive. [0004] However, if for some reason the "big mo...
