Abstract

See full text

A power supply control device includes a first system, a second system, an inter-system switch, a battery switch and a controller. The controller turns off an inter-system switch that connects and disconnects the systems and turns on a battery switch that connects and disconnects a second power supply to and from the second system in response to an abnormality of a first power supply or the second power supply being detected and thereafter turn on the inter-system switch and turns off the battery switch in response to determination that there is no abnormality in the power supplies. Before turning on the inter-system switch, when voltage difference between the power supplies is equal to or larger than a threshold, the controller performs convergence control, and after determining that there is no abnormality in the power supplies, the controller keeps the battery switch turned off while performing the convergence control.
