Abstract
In the charging device, when the secondary battery is charged, charging electrodes are electrically connected to the battery electrodes. When charging of the battery is completed, charging operation of the charging device is completed, and the charging electrodes are moved away from the battery electrodes so that the charging electrodes are disconnected from the battery electrodes.
Claims16
A charging device for charging a secondary battery, said charging device having a plurality of charging electrodes for supplying electrical current, said secondary battery having a plurality of battery electrodes through which said electrical current is supplied from said plurality of charging electrodes, said device comprising:
- a charging completion detector for detecting whether charging of said secondary battery is completed;
- a mechanism for insulating connection between said plurality of charging electrodes with said plurality of battery electrodes when said charging completion detector detects that the charging of said secondary battery is completed.
A charging device for charging a secondary battery, said charging device having a plurality of charging electrodes for supplying electrical current, said secondary battery having a plurality of battery electrodes through which said electrical current is supplied from said plurality of charging electrodes, said device comprising:
- a first mechanism for allowing said plurality of charging electrodes to contact said plurality of battery electrodes, said first mechanism being neutrally effected;
- a second mechanism for insulating said plurality of charging electrodes from said plurality of battery electrodes;
- and
- a controller for activating said second mechanism when charging of said second battery is not being executed.
