Abstract

PURPOSE:To prevent judgment as the completion of charging under the state of insufficient charging, and to obviate the shortage of charging by connecting a malfunction preventive circuit to a detector detecting the completion of charging from the state of an output from a charging-voltage output circuit. CONSTITUTION:A charging type battery 5 is charged through a charging-voltage output circuit 2 from a power circuit 1. A charging-completion detector 3 is connected to the charging-voltage output circuit 2, and the completion of charging is detected by the state of an output from the charging-voltage output circuit 2. A charging-completion malfunction preventive circuit 4 is connected to the charging-completion detector 2, and the erroneous detection of the completion of charging is prevented. A delay circuit is formed by a capacitor C3, and the correct completion of charging is identified when the state of the detection of the completion of charging continues for a fixed time or more, thus obviating erroneous detection due to the instantaneous service interruption of a power supply, the defective mounting of the battery, etc.
