Accumulator charge and discharge control circuit - measures load and charge times to ensure constant charge rate irrespective of loading

TLDR: A charge and discharge control circuit for portable accumulator sets is described in this article, which is based on maintaining a constant charge rate dependent on the measured discharge time, which is measured by reference to a pulse generating clock source followed by a programmable divider.

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
