Abstract
PURPOSE:To prevent the span of the life of a battery from being shortened, by switching trickle charge to boosting charge again, in case that the trickle charge is kept forover a fixed time. CONSTITUTION:When boosting charge is executed via a boosting charge circuit 1, and when voltage drop is detected, than a - V detecting circuit 4 is worked, and a switch 3 is charged over to the side of a trickle charge circuit 2, and trickle charge is executed. At the same time, timing is started by a timer 5, and when the trickle charge is kept for a fixed time, then the switch 3 is changed over to the side of the boosting charge circuit 1 again. By this method, till the - V detecting circuit is worked again, the boosting charge is executed. Even in case that discharge more than trickle charge quantity is generated under the trickle charge, charging voltage can be recovered by executing the boosting charge.
