ABSTRACT:
This automatic battery charging circuit has two independent channels for charging first and second batteries respectively. Circuit control means in the battery charging circuit enable it to provide charging current in proportion to the state of charge of the two batteries. First and second electronic bar displays are connected to the two channels by wires. The channels provide readings which indicate the state of charge of each battery. The state of charge of each battery is sensed only when no charging current flows to each battery. Computer components in the circuit control means compute the charge level of each battery and this charge level is indicated by the respective bar displays.
