Abstract

A method for interconnecting cell stacks of a battery module in a battery. In the battery module, the cell stacks are arranged in a battery module housing. In each case two cell stacks are arranged next to one another and form a cell stack group, and the two cell stack groups are arranged behind one another. The two cell stacks of the first cell stack group are inserted into the battery module housing. The two cell stacks of the first cell stack group are electrically interconnected via at least one opening arranged in a wall of the battery module housing. The two cell stacks of the second cell stack group are inserted into the battery module housing. Electrically interconnecting the two cell stacks of the second cell stack group to each one of the two cell stacks of the first cell stack group.
