Abstract

The present invention relates to a battery charger (30) including a housing (40), having an electronic charging unit (33) and a cradle (31) for a battery pack (10) that has electric counter-contact elements (38) for contact elements (18) of the battery pack (10). The battery charger (30) also has a filling device to fill gas reservoirs such as, for instance, pressure vessels, with gaseous media, said filling device being configured as a compressor to generate compressed air.

Claims

1. A battery charger comprising:

a housing;

an electronic charging unit;

a cradle for a battery pack, the cradle having electric counter-contact elements for contact elements of the battery pack; and

a filling device to fill at least one gas reservoir with gaseous media.

2. The battery charger according to claim 1 wherein the filling device includes a compressor generating compressed air, the compressor pneumatically connected to at least one connector for an output port of the at least one gas reservoir.

3. The battery charger according to claim 1 wherein the counter-contact elements and the at least one connector are arranged on a shared counter-connection port.

4. The battery charger according to claim 1 wherein the filling device can be controlled via the electronic charging unit.

5. The battery charger according to claim 1 wherein the compressor is electrically connected to the electronic charging unit.
