Abstract

Electric cells (6) placed inside a housing (1) are in thermal contact with a Peltier cell providing heat transfer into or out of a cell pack, whereas thermo-conducting separating plates (5) contacting with at least one side wall (2) are placed inside said housing with the electric cells (6) placed between the plates (5), and the side wall (2) of the housing (1) being in contact with said separating plates (5) is in thermal contact with said Peltier cell (8).

Claims

1. A thermo-stabilized electrical battery module in which electric cells are placed inside a housing and are in thermal contact with a Peltier cell transferring heat from or to an electric cell pack, characterized in that thermally conductive separating plates which remain in contact with at least one side wall of the housing are clamped inside the housing with the electric cells placed between said separating plates, whereas said side wall of the housing contacting with the separating plates is in a thermal contact with the Peltier cell and the electric cells are clamped by the thermally conductive plates with their largest faces, while the Peltier cell is in thermal contact with a liquid heat exchanger.

3. A module according to claim 1, characterized by that the liquid heat exchanger comprises a radiator and a cooling fluid collector with inlet and outlet openings.

4. A module according to claim 1, characterized by that the Peltier cell together with the liquid heat exchanger are placed in a positioning frame and are pressed by means of double-sided screws through a fastening plate essentially against a middle part of the side wall of the housing.

5. A module according to claim 1, characterized by that the electric cells placed in the housing and separated by the separating plates are clamped together by means of double sided screws.

6. A module according to claim 1, characterized by that the separating plates have their back edges bent at an angle of 90°

contacting with the side wall.

7. A module according to claim 6, characterized by that the separating plates are riveted together with the side wall of the housing.

8. A module according to claim 1, characterized by that the separating plates, as well as the side wall of the housing are made of aluminum.
