Abstract

PURPOSE: To prevent a decrease in the life of a secondary cell due to overcharging by allowing quick charge only when predetermined power is consumed from the cell or the cell is replaced after the fully charged state of the cell is detected.
CONSTITUTION: A charging type is switched by a DC/DC converter 3 in response to a command signal generated from a charge/discharge controller 8. the controller 8, if it detects a fully charged state of a secondary cell 1 during quick charging, stands a full charge flag, and outputs a command signal to the converter 3 to switch the type to a trickle change. The full charge flag inhibits quick charging to the cell while it is being stood, and the controller 8 is restricted by the flag. Accordingly, while this flag is being stood, a switching command signal for switching the trickle charge to the quick charge is inhibited by the controller 8 for the converter 3. The detection of the full charge state of the cell 11 is detected by so-called -▵V type.
