Battery cluster charger having a backup charging system
First Claim
1. A battery cluster charger comprising:
- a plurality of charging circuits for charging a plurality of battery packs;
each of said charging circuits having means for outputting a failure signal upon a failure thereof and outputting a full-charge signal upon fully charging one of the battery packs;
a battery connection detector for detecting connections of the battery packs respectively to the charging circuits;
a charging switcher connected between the charging circuits and the battery packs connected respectively thereto, for switching to one of the charging circuits for charging the battery packs; and
a control circuit responsive to the failure signal and the full-charge signal from each of said charging circuits, for controlling said charging switcher to stop charging one of the battery packs with one of the charging circuits which outputs the failure signal and to successively charge the battery packs with the other charging circuits until the fully-charge signals are outputted thereby.

Abstract
A battery cluster charger has a plurality of charging circuits for charging a plurality of battery packs. When one of the charging circuits suffers a failure and cannot charge a corresponding battery pack, it is replaced with another of the charging circuits to charge the battery pack. The battery cluster charger includes a charging switcher for switching one of the charging circuits to charge the battery packs, a battery connection detector for detecting connections of the battery packs respectively to the charging circuits, and a control circuit responsive to a failure signal and a full-charge signal from each of the charging circuits, for controlling the charging switcher to stop charging one of the battery packs with one of the charging circuits which outputs the failure signal and to charge the battery packs with the other charging circuits until the fully-charge signals are outputted thereby.
