Abstract

PURPOSE:To improve the safety by stopping the charging action of a battery to be charged when it is inferior. CONSTITUTION:Power from a commercial power supply 100 is rectified by a rectifier smoothing circuit 1 and controlled by a charging control circuit 2, and a storage battery 4 is changed through a switching circuit 3. The charging characteristics, which shows a corresponding relation between charging time and battery voltage, is stored in a memory 7. Simultaneously with a start of charging, a switch control circuit 5 starts a timer 6, counting the charging time. The timer 6 informs the switch control circuit 5 of an elapse of the specified time from the start of charging. In this point of time, the switch control circuit 5 judges whether or not the storage battery 4 generates its voltage in a value stored in the memory 7, continuing the charging when the judgement proves YES. When NO, this storage battery 4 is judged as improper, and the switching circuit 3 is opened, stopping the charging action.
