CONTROL DEVICE FOR POWER SUPPLY DEVICE

WIPO Patent Application WO/2020/209132

A1

A control device (21) is applied to a power supply device provided with a first switch (SW1, SW3) provided in a first electric path connecting a first storage battery (11) and an electric load (14, 15), and a second switch (SW2, SW4) provided in a second electric path connecting a connection point closer to the electric load than the first switch in the first electric path and a second storage battery (12), and, when performing a switch changeover from a state in which one switch is on to a state in which the other switch is on, provides an overlap period during which both the switches are on. The control device is provided with: a determination unit that determines whether a potential difference between first voltage of the first storage battery and second voltage of the second storage battery is larger than a predetermined value or not; and a switch control unit that, if the potential difference is determined to be smaller by the determination unit, performs, as first control, a switch changeover after the overlap period is provided, and if the potential difference is determined to be larger by the determination unit, performs second control for suppressing conduction between the storage batteries in place of the first control.
