Abstract

A charge and discharge control circuits is for accumulator banks esp. portable accumulator sets subject to repeated charge and discharge cycles. Control is based on maintaining a constant charge and discharge rate dependent on the measured discharge time. This is measured by reference to a pulse generating clock source followed by a programmable divider. A decoder is fed with state of charge data and directly controls the charge switching circuit. A luminescent diode driven from a logic controlled transistor provides indication of the end of charge, a similar diode signals the point when the battery is more than half charged.
