BATTERY PACK
First Claim
1. A battery pack usable as a power source for an electric device, comprising:
- a battery cell group in which a plurality of battery cells are interconnected in series;
discharge control circuitry for converting DC voltage of the battery cell group into AC voltage;
an AC-output terminal through which an output of the discharge control circuitry is supplied to the electric device;
charge control circuitry for converting AC voltage of a commercial power source into DC voltage, to thereby charge the battery cell group;
a charging terminal through which electric power of the commercial power source is supplied into the battery cell group; and
a case within which the battery cell group, the discharge control circuitry, the AC-output terminal, the charge control circuitry and the charging terminal are housed,wherein the AC-output terminal is connectable with a power-input connector of the electric device which is powered by the commercial power source, andthe charging terminal is connectable with a charging connector of the commercial power source,the battery pack further comprising an insertion detector disposed within the case, for detecting insertion of the power-input connector into the AC-output terminal,wherein the discharge control circuitry initiates a discharge control sequence for the battery cell group, if the insertion of the power-input connector is detected, and does not initiate the discharge control sequence, in response to non-detection of the insertion of the power-input connector.
