Abstract
An object of the invention is to make the charging power as high as possible in a battery charging control system for selectively charging a plurality of batteries having different voltages with energy generated by an alternator. To achieve the object, the battery charging control system according to the invention includes an alternator having a variable generation voltage and a plurality of batteries having different charging voltages, wherein maximum generation power defined as the highest power that the alternator can generate and maximum charging power defined as the highest power that each battery can accept are obtained, and a battery for which the charging power is highest is selected to be charged based on a comparison of the maximum generation power and the maximum charging power.
