Abstract

A battery arrangement (1) has at least two battery cell packs (2, 3) arranged in a common battery housing (4). The battery housing (4) has at least one first opening (5) for supplying cooling air and at least one second opening (6) for discharging heated air. The battery cell packs (2, 3) are arranged one above the other and delimit a tunnel (7) therebetween in a height direction. At least one of the first and second openings (5, 6) is arranged substantially at the same level as the tunnel (7). The tunnel (7) is closed at a side facing one of the first and second openings (5, 6) so that air flowing between the first and second openings (5, 6) is channeled through or around the battery cell packs (2, 3).

Claims

1. A battery arrangement having at least two battery cell packs arranged in a common battery housing, the battery housing having at least one first opening for supplying cooling air and at least one second opening for discharging heated air, the battery cell packs being arranged one above the other and delimiting a tunnel therebetween in a height direction, at least one of the first and second openings being arranged substantially at the same level as the tunnel and the tunnel being closed at a side facing one of the first and second openings so that air flowing between the first and second openings is channeled through or around the battery cell packs.

2. The battery arrangement of claim 1, wherein at least the first opening is arranged substantially at the same level as the tunnel and the tunnel is closed at a side facing the second opening so that air flowing in through the first opening flows through the tunnel, through or around the battery cell packs and out via the second opening.

3. The battery arrangement of claim 1, wherein at least the second opening is arranged substantially at the same level as the tunnel and the tunnel is closed off at a side facing toward the first opening so that air flowing in through the first opening flows through or around the battery cell packs, into the tunnel and out via the second opening.

4. The battery arrangement of claim 1, wherein the battery cell packs are constituent parts of a high-voltage battery.

5. The battery arrangement of claim 4, wherein the high-voltage battery is a battery with sufficient power for operating a hybrid vehicle.

6. The battery arrangement of claim 1, further comprising a fan arranged in communication with at least one of the first and of the second openings.

7. The battery arrangement of claim 1, further comprising brackets in the battery housing and supporting the battery cell packs in the battery housing.

8. The battery arrangement of claim 1, wherein the first and second openings are arranged on opposite sides of the battery housing.

9. A hybrid vehicle having a battery arrangement with at least two battery cell packs arranged in a common battery housing, the battery housing having at least one first opening for supplying cooling air and at least one second opening for discharging heated air, the battery cell packs being arranged one above the other and delimiting a tunnel therebetween in a height direction, at least one of the first and second openings being arranged substantially at the same level as the tunnel and the tunnel being closed at a side facing one of the first and second openings so that air flowing between the first and second openings is channeled through or around the battery cell packs.
