Abstract

A battery pack provided by the present invention comprises a shell which comprises an upper shell and a lower shell, wherein the upper shell and the lower shell define an accommodating cavity; a plurality of battery cells which are arranged in the accommodating cavity and form a plurality of rows of battery cell assemblies, wherein the plurality of rows of battery cell assemblies are parallel, andthe plurality of battery cells in each row of battery cell assemblies are sequentially stacked along the length direction of the shell; a supporting structure which is supported between the lower shell and the plurality of battery cells, and is connected with the lower shell and the plurality of battery cells so as to fix the plurality of battery cells to the lower shell. Therefore, the pluralityof battery cells are stacked into the plurality of rows of battery cell assemblies, in the process of producing the battery pack, the plurality of battery cells do not need to be arranged into a battery module firstly, and the number of the battery cells arranged in the battery pack can be increased, so that the cruising ability of the battery pack can be improved. In addition, the plurality of battery cells can be reliably fixed on the lower shell through the arrangement of the supporting structure, and the battery cells can be prevented from loosening.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack. Background technique [0002] In the related art, in the process of producing battery packs, the cells are first set up as battery modules, and then the battery modules are assembled in the casing of the battery pack. Assembling multiple batteries into a battery module results in the addition of unnecessary components in the battery pack, which affects the number of batteries in the battery pack, resulting in poor endurance of the battery pack. Moreover, the battery cell cannot be well fixed in the casing of the battery pack, resulting in the battery cell being easily loosened, which affects the safety of the battery pack. Contents of the invention [0003] In view of this, the present invention aims to provide a battery pack, which can solve the problem of poor endurance of the battery pack and also solve the problem of loose batteries. [0004] In order to...
