    • PROBLEM TO BE SOLVED: To provide a power storage system installed on a vehicle, capable of discriminating a deposition state of a charging relay.SOLUTION: Charging relays (DFR-H, DFR-C) switches between on and off states by receiving an input of a driving signal. When the charging relay is under an on state, DC power is supplied from a charger (100) mounted outside a vehicle to a storage device (10). When the charging relay is under an off state, supply of DC power to the storage device is shut down. A detection unit (50) is connected with connection lines (PL2, NL2) for connecting the storage device and the charger and switches an output signal according to an on/off state of the charging relay. A controller (30) compares an output signal of the detection unit to a driving signal of the charging relay to discriminate a deposition state of the charging relay.
