ABSTRACT:
A battery is charged in three successive charging intervals. In the first charging interval, charging is continued For a fixed time regardless of battery voltage change. In the second charging interval, charging is ceased by detecting a voltage drop from a peak battery voltage. In the third charging interval, charging is ceased by detecting the peak battery voltage. Early disconnect as well as over-charging are prevented.
