Method for producing a battery module, and battery module

Abstract

The invention relates to a method for producing a battery module which comprises a plurality of battery cells, in which method a module housing (12) of the battery module is provided in a first step. A core arrangement (20) is introduced into the module housing (12), wherein a hollow space, which is to be provided in a cured encapsulation compound (26), is defined by a respective core (22) of the core arrangement (20). The encapsulation compound (26) is then introduced (S14) into the module housing (12). After the encapsulation compound (26) has been allowed to cure and the core arrangement (20) has been removed from the module housing (12), an electrode arrangement, which is associated with the respective battery cell, is arranged in the hollow space which is formed in the cured encapsulation compound (26). The invention further relates to a battery module.

Description

technical field

[0001] The invention relates to a method for producing a battery module comprising a plurality of cells / cells. The invention also relates to a battery module including a plurality of battery cells. Background technique

[0002] To provide high-voltage batteries for electric vehicles and hybrid vehicles, battery modules are used which each include a plurality of battery cells. Usually, in such battery modules, the battery cells are electrically connected to one another and are subjected to a contact force, which prevents the walls of the cell housings of the individual battery cells from buckling upwards. Prismatic battery cells are usually used in such battery modules, which are arranged upright next to one another and can therefore be electrically connected to one another in a relatively simple manner. Since prismatic battery cells generally have a cell housing made of metal, it is necessary to electrically insulate these battery cells from one another. I...
