Abstract
A method for controlling a vehicular electric system having multiple power sources including an engine-driven generator. The power sources for supplying power to charge an onboard battery are determined based on difference between the power generation cost of each power source and that for generating an amount of power charged in the battery. Furthermore, amounts power to be supplied to the battery 103 for charge is determined based on the amount of power currently charged in the battery.
