Abstract

An electric power supply control system includes a plurality of electric power supply systems and a controller connected to the electric power supply systems. Each of the electric power supply systems includes a first secondary battery, a first load, a second secondary battery, a second load, and a DC-DC converter connected between the first secondary battery and the first load, and the second secondary battery and the second load. When a charge voltage of the first secondary battery of a first electric power supply system that is any one of the electric power supply systems becomes higher than the charge voltage of the first secondary battery of an electric power supply system other than the first electric power supply system by a predetermined voltage or more, the controller increases a level of output from a specific load in the first electric power supply system.
