Relay device

A relay device comprising:

• a capacitor included in a charger;
• a discharge circuit that discharges electric charge charged to the capacitor,
• wherein the discharge circuit includes:
• a discharge resistance,
• a first relay switch connected in series to the discharge resistance and having a contact point that becomes a closed state by electric conduction to an exciting coil, and
• a second relay switch connected in parallel to the first relay switch and having a contact point that becomes an open state by electric conduction to an exciting coil,
• a controller, wherein the controller, by mutually switching between a state in which the first relay switch is turned on and the second relay switch is turned off and a state in which the first relay switch is turned off and the second relay switch is turned on, determines abnormality of the first relay switch and the second relay switch;
• wherein, the capacitor is connected in parallel to the connection in series of the first relay switch and the discharge resistance.
