Beschreibung
Zusammenfassung:	A switching device is mounted in a vehicle, and disposed between a connector connected to a DC power source, and a storage battery. The switching device includes: a transmission path connecting the connector and the storage battery; a semiconductor relay disposed on the transmission path; a switch disposed on the transmission path; a first sensor configured to measure a current flowing through the semiconductor relay, or a voltage of the semiconductor relay; and a controller configured to control opening and closing of the semiconductor relay. The switch is controlled by an external control signal, and the controller controls the semiconductor relay, based on the control signal and a measurement value of the first sensor.
