Abstract
The described technology provides a method of balancing power supplied to a system load by a first battery power source and a second battery power source. The method includes sensing a first current supplied by or supplied to the first battery source. The method further includes changing a control voltage for a voltage converter circuit based on the sensed first current, an input of the voltage converter circuit being coupled to the second battery power source, an output of the voltage converter circuit being electrically coupled to the system load. The method still further includes adjusting the voltage converter circuit to modify a charge current supplied from the second battery power source to the first battery power source based on the control voltage.
