Abstract

The invention relates to a battery box. The battery box comprises a single battery and a lower box, wherein the single battery comprises a top cover and a shell, and the top cover is hermetically connected above the shell; the shell comprises a first surface and a second surface, wherein the first surface and the second surface are oppositely arranged; the area of the first surface is larger thanthat of the second surface; the lower box body comprises a bottom plate arranged on the bottom surface and side plates on the side surfaces, and an opening is formed in the upper part of the lower boxbody; a reinforcing beam is arranged on the pair of opposite side plates of the lower box body; and at least one first surface of the single battery is in contact with the side plates or the reinforcing beam of the lower box body. The reinforcing beam arranged on the pair of opposite side plates of the lower box body can effectively enhance the strength of the side plates of the lower box body, and the single batteries are directly arranged in the lower box body in columns, so that a heavy module end plate structure is omitted, the overall production cost of the battery box is lowered, and the battery box is also effectively made to be lightweight.

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...
