1. A battery module housing for receiving multiple battery cells, comprising:
a plurality of battery cell receiving regions,
a circuit board receiving region, wherein the circuit board receiving region lies adjacent to the battery cell receiving regions;
a plurality of cell connector receiving regions, wherein the cell connector receiving regions are provided adjacent to at least some of the plurality of battery cell receiving regions and each cell connector receiving region is an elongated cell connector receiving region adapted to receive an elongated connection section of a cell connector; and
at least one centering unit within at least one of the cell connector receiving regions, wherein the at least one centering unit is adapted to guide the elongated connection section of the cell connector received by the respective cell connector receiving region into contact with a circuit board positioned within the circuit board receiving region.
 
19. A battery module housing for receiving multiple battery cells, comprising:
a plurality of battery cell receiving regions,
a circuit board receiving region, wherein the circuit board receiving region lies adjacent to the battery cell receiving regions;
a plurality of cell connector receiving regions, wherein the cell connector receiving regions are provided adjacent to at least some of the battery cell receiving regions; and
at least one centering unit within at least one of the cell connector receiving regions;
wherein the at least one centering unit has at least two centering elements that collectively define an opening cross-section through which a connection section of the cell connector can be pushed inserted in an insertion direction, the opening cross-section being reduced in the insertion direction in order to guide and center the cell connector, and wherein the centering elements are designed as flexible tabs.
 
20. A battery module, comprising:
a plurality of battery cell receiving regions each containing a battery cell;
a circuit board receiving region containing a circuit board, wherein the circuit board receiving region lies adjacent to the battery cell receiving regions;
a plurality of cell connectors, each comprising an elongated connection section;
a plurality of cell connector receiving regions, wherein the cell connector receiving regions are provided adjacent to at least some of the plurality of battery cell receiving regions and each cell connector receiving region is an elongated cell connector receiving region adapted to receive the elongated connection section of one of the plurality of cell connectors; and
at least one centering unit within at least one of the cell connector receiving regions, wherein the at least one centering unit is adapted to guide the elongated connection section of the cell connector received by the respective cell connector receiving region into contact with the circuit board.
