Problems solved by technology

In addition hardening of plastics is difficult because of the long hardening times required
Heating for accelerated hardening is therefore not possible, since the battery cells should not be subjected to a corresponding temperature increase

Embodiment Construction

[0032] according to figure 1 description in manufacture Figure 7 A first step S10 for the battery module 10 shown in the final state. In a first step S10 , an empty module housing 12 is provided, which currently has a bottom 14 and side walls 16 . The module housing 12 forms the wall of the completed battery module 10 (see Figure 7 ). The module housing 12 is sufficiently stable so that it can absorb the forces occurring in the battery module 10 . This force, which acts in particular on the side walls 16 of the module housing 12 , originates from a chemical reaction which takes place in the individual battery cells 18 of the battery module 10 when the battery module 10 supplies a voltage.

[0033] In the second step S12 (see figure 2), a core arrangement 20 comprising a plurality of cores 22 is arranged in the module housing 12 . The core 22 forms a negative mold for the electrode arrangement 24 of the individual battery cells 18 (see Figure 6 ).

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...
