Abstract: In a storage-battery control system, an insulating communication unit couples a controller to a battery module constituting a storage battery unit that outputs a predetermined high voltage value. A power supply line is further provided for supplying electric power output from a controller DC/DC, i.e., a controller-side voltage converter for the controller, to the battery module, so that electric power is collectively supplied via the power supply line to a module CPU and a module-side insulating circuit both consuming electric power in the battery module. A secondary battery in the battery module supplies electric power to only a cell-voltage detector.
