Claim Text:
1. A battery arrangement for a motor vehicle, comprising: a battery housing having an outer wall; a printed circuit board mounted to the battery housing and spaced from the outer wall to define a first flow space between the outer wall and the printed circuit board, and openings formed through the printed circuit board; a cell connecting element mounted to the printed circuit board and having opposite first and second surfaces, the first surface facing the printed circuit board and spaced therefrom to define a second flow space between the cell connecting element and the printed circuit board, the first flow space and the second flow space being in communication with each other through the openings in the printed circuit board, the cell connecting element being formed with openings extending therethrough at locations offset from the openings in the printed circuit board; and battery cells provided respectively with cell poles mounted to the second surface of the cell connecting element at positions opposed respectively to the openings in the printed circuit board, the battery cells being spaced from one another to define third flow spaces between the battery cells and aligned with the openings in the cell connecting element, the third flow spaces being in communication with the second flow space via the openings in the cell connecting element, so that the battery arrangement is configured to allow a cooling medium to flow from the first flow space into the second flow space at locations opposed to the cell poles via the openings in the printed circuit board, and into the third flow space between the battery cells via the openings in the cell connecting element to cool the battery arrangement.
