ABSTRACT:
A circuit for regulating the amount of electrical re-charging current supplied to a battery is disclosed. The circuit includes a first generator for generating a signal representing the desired amount of the re-charging current, a second generator for generating a signal representing the actual amount of the re-charging current, and a comparator responsive to the desired and actual current signals for controlling the actual amount of the re-charging current to correspond to the desired amount. The desired signal generator includes a plurality of individual current signal sources. Each of the individual current signal sources is separately controlled by a microprocessor to selectively generate individual current signals. All of the individual current signals are summed together to provide the desired current signal.
