Abstract

A battery system is disclosed which includes: a battery assembly; an AC-voltage generator for generating alternate current (AC) voltage from direct current (DC) voltage of the battery assembly; a battery charger for charging the battery assembly; and a detector for detecting application of AC voltage from the AC-voltage generator to the battery charger.

Claims

1. A battery system comprising:

a battery assembly;

an AC-voltage generator for generating alternate current (AC) voltage from direct current (DC) voltage of the battery assembly;

a battery charger for charging the battery assembly; and

a detector for detecting application of AC voltage from the AC-voltage generator to the battery charger.

2. The battery system of claim 1, further comprising an electrically-operated switch configured to operate such that, in the presence of AC voltage inputted into the battery charger, the switch connects an output port of the AC-voltage generator with an input port of the battery charger, and, in the absence of AC voltage inputted into the battery charger, the switch does not connect the output port of the AC-voltage generator with the input port of the battery charger.

3. The battery system of claim 1, further comprising a controller configured to at least partially inhibiting the AC-voltage generator from affecting the battery charger, in response to detection of the application of the AC voltage from the AC-voltage generator to the battery charger.

4. The battery system of claim 1, further comprising an indicator providing an indication varying in response to detection of the application of the AC voltage from the AC-voltage generator to the battery charger.
