Abstract

The invention relates to a battery box. The battery box includes: a casing, the casing includes a bottom plate and a side plate; a first battery unit is arranged on the bottom plate; a second battery unit is arranged in the casing and stacked with the first battery unit in a first direction; wherein, The first battery unit includes a plurality of first battery modules arranged side by side along the second direction, the first upper cover of each first battery module is facing away from the bottom plate, and the first direction is perpendicular to the second direction; the second battery The unit includes a plurality of second battery modules arranged along the second direction, and the second upper cover of each second battery module faces the side plate; the number of the second battery modules is greater than the number of the first battery modules. The battery box of the embodiment of the present invention has the first battery unit and the second battery unit arranged in different ways, and the structure of the first battery unit and the second battery unit is more compact, so that the space inside the battery box can be fully utilized, so that the battery box as a whole Compact structure.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a battery box. Background technique [0002] With the continuous development of science and technology, power batteries are more and more widely used in daily production and life. In the related technology, for the battery system, it can be divided into battery box, battery module and single battery according to the system level from high to low. Most of the battery modules produced by domestic and foreign lithium battery manufacturers are based on single battery It is the smallest unit, that is, a single battery is produced first, and is equipped with a corresponding protection device, and then a battery module is assembled by connecting multiple single batteries in parallel and in series. Multiple battery modules form a battery box. In the prior art, the battery modules in the battery box are directly stacked on top of each other, and the space utilization rate is low...
