Problems solved by technology

However, because the top frame 40 is added to the upper portion of the monocoque stack 10, it is more difficult to meet assembly dimensional tolerances that allow the monocoque stack 10 to be assembled to fit into the width of the monoframe, thereby reducing yield during the assembly process.

Abstract

The present invention relates to a battery module and a battery pack having an ICB assembly of a space-saving structure, the battery module comprising: a cell stack having a plurality of battery cells stacked in one direction; and being electrically connected to the plurality of battery cells ICB components to sense voltage information. The ICB assembly includes: a front bus bar frame assembled to the front side of the cell stack and a rear bus bar frame assembled to the rear side of the cell stack, the front bus bar frame and the rear bus bar frame respectively have electrode leads connected to the battery cells a plurality of bus bars in contact; a sensing component assembled such that one side thereof is fixed to a front bus bar frame and the other side thereof is fixed to a rear bus bar frame; and at least one bridge plate, the bridge The plates are connected to the front bus bar frame and the rear bus bar frame to keep the gap between the front bus bar frame and the rear bus bar frame constant.

Description

Technical field[0001]The present disclosure relates to a battery module, and more particularly, the present disclosure relates to such a battery module: an ICB component facilitating increasing the energy density is applied to the battery module.[0002]The priority of the Korean Patent Application No. 10-2018-0120759 submitted in South Korea on October 10, 2018, which is incorporated herein by reference.Background technique[0003]Recently, a secondary battery is proposed as a solution for solving air pollution problems caused by existing gasoline and diesel vehicles using fossil fuel, so that secondary batteries are used as an electric vehicle (EV) and hybrid electric vehicle (HEV) The power supply is concerned.[0004]In a smaller mobile device, each device uses one or several battery cells. However, medium or large devices such as vehicles use a medium-sized or large battery module that is electrically connected to a plurality of battery cells due to high power and large capacity, or ...
