Abstract
The present disclosure is directed to a system including a power source connected to at least two electrical buses, and a battery connected to each one of the electrical buses. Each battery is charged by the power source and is connected to a load via one of the electrical buses. A battery error signal generator generates a battery error signal for each battery by finding a difference between a sensed battery voltage and a reference voltage. A reference control signal generator generates a reference control signal for each battery based on the battery error signals for each battery. A power sensor produces a sensed power signal between the power source and each battery connected to each of the two electrical buses. The reference control signal and the sensed power signal for each battery controls a power output value from the power source to each battery.
