Abstract

A cell holder for a battery cell includes an intake in which the battery cell is receivable. The cell holder is stackable with additional cell holders in a module frame in which a battery that has a plurality of battery cells is receivable. The cell holder is guidable in the module frame relative to the module frame by a guiding device.

Claims (17)

1 . A cell holder ( 10 ), comprising:

a battery cell ( 12 );

an intake ( 22 ) in which the battery cell ( 12 ) is disposed;

wherein the cell holder is stackable with additional cell holders ( 10 ) in a module frame;

a guiding device ( 26 ) disposed on a side wall ( 20 ) of the cell holder ( 10 ), wherein the cell holder ( 10 ) is guidable in the module frame relative to the module frame by the guiding device ( 26 ); and

a bending edge ( 30 ) disposed on the side wall ( 20 ), wherein a cell tab ( 32 ) of the battery cell ( 12 ) is bent around the bending edge ( 30 );

wherein a lateral metal insert ( 34 ) is provided on the bending edge ( 30 ), wherein the lateral metal insert ( 34 ) is formed in the side wall ( 20 ), and wherein the cell tab ( 32 ) abuts on the lateral metal insert ( 34 ) and is welded to the lateral metal insert ( 34 ).

2 . The cell holder ( 10 ) according to claim 1 , wherein the guiding device ( 26 ) is a dovetail guide.

3 . The cell holder ( 10 ) according to claim 1 , further comprising a metal component with a wall, wherein the wall delimits the intake ( 22 ) and the battery cell ( 12 ) abuts the metal component.

4 . The cell holder ( 10 ) according to claim 1 , further comprising a heating element disposed on a wall that delimits the intake ( 22 ), wherein the battery cell ( 12 ) abuts the heating element.

5 . A cell module, comprising:

a module frame, wherein the module frame has a guide intake; and

at least two cell holders ( 10 ) according to claim 1 that are held on the module frame stacked on top of one another in a stacking direction ( 24 );

wherein the at least two cell holders ( 10 ) are guidable along the stacking direction in the guide intake relative to the module frame by the respective guiding devices ( 26 ) of the at least two cell holders ( 10 ).

6 . The cell module according to claim 5 , further comprising a metal component ( 36 ) that abuts on a first side of a back wall ( 14 ) of a first cell holder ( 10 ) of the at least two cell holders ( 10 ), wherein a battery cell ( 12 ) disposed in a second cell holder ( 10 ) of the at least two cell holders ( 10 ) abuts on a second side of the back wall ( 14 ) opposite the first side.

7 . The cell holder according to claim 5 , further comprising a cooling device that abuts on the at least two cell holders ( 10 ), wherein heat is gatherable from the at least two cell holders ( 10 ) by the cooling device.

8 . The cell module according to claim 7 , further comprising a metal component ( 36 ), wherein the metal component ( 36 ) is disposed on a base wall ( 16 ) of one of the at least two cell holders ( 10 ) that abuts the cooling device.
