A configuration can supply a charging current from a power generator to two power storage devices, and can suppress, if an abnormality occurs on one power storage device side, the abnormality from affecting the other power storage device side. A relay device includes: a first switch configured to interrupt a first conductive path ; a second switch configured to interrupt a second conductive path ; a bypass circuit with a series circuit in which a resistor and a third switch are connected in series to each other, the series circuit having one end electrically connected to a portion between the first switch and the first power storage device, and another end electrically connected to a portion between the second switch and the second power storage device; and a controller configured to turn the first switch, the second switch, and the third switch on/off.
