Abstract

The invention relates to a battery box, comprising: a battery cell, the battery cell includes a top cover and a casing, the top cover is sealed and connected above the casing, the casing includes a first surface oppositely arranged and The second surface oppositely arranged, the area of ​​the first surface is larger than the area of ​​the second surface, the lower box includes a bottom plate arranged on the bottom surface and a side plate on the side, and the upper part has an opening, and the lower box is opposite Reinforcement beams are arranged on a pair of side plates of the lower case, and at least one first surface of the battery cell is in contact with the side plates or the reinforcement beams of the lower case. The reinforcing beams arranged on the opposite side panels of the lower box can effectively enhance the strength of the side panels of the lower box, and directly place the battery cells in a row in the lower box, eliminating the need for a heavy module end plate structure. That is, the overall production cost of the battery box is reduced, and the weight of the battery box is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of energy storage devices, in particular to a battery box. Background technique [0002] After the batteries are combined in series and parallel to form a module, each module is installed in the battery box. The module usually includes two module end plates. The function of the module end plate is to resist the expansion force of the battery cell. The battery box The lower box body is mainly made of sheet metal stamping or tailor-welded aluminum profiles. The battery box itself is heavy, and the weight of the modules installed in the battery box makes the battery box as a whole heavier. In order to reduce the overall weight of the battery box, lightweight materials such as carbon fiber are often used to make the lower box body, but the cost of these lightweight boxes alone is high and the production efficiency is low. Contents of the invention [0003] Therefore, it is necessary to provide a battery box t...
