ABSTRACT:
A starter/generator in combination with a dual battery dual voltage motor vehicle electrical system and an equalization circuit for maintaining substantially equal charge on the batteries. In starting, the starter/generator is operated as an equivalent series motor from the serial combination of the two batteries to crank the engine. Upon starting, the starter/generator supplies charging current at one or the other of the system voltages, depending on the engine speed. At all times, the equalization circuit transfers energy from one battery to the other as required to maintain balanced battery voltages.
