A charging device for a vehicle, the charging device being configured to be capable of charging by a power supply outside said vehicle a power storage device mounted on said vehicle for driving the vehicle, said vehicle being connectable to said power supply by a coupler capable of transmitting electric power from said power supply to said vehicle, said charging device comprising: a connector provided to said vehicle and configured such that said coupler is connectable to the connector; a power feeding unit mounted on said vehicle and configured to transmit said electric power from said connector to said power storage device; a charging control unit mounted on said vehicle, configured to charge said power storage device by controlling said power feeding unit while the charging control unit is in an operating state, and configured to halt control of said power feeding unit while the charging control unit is in a halting state; and an activation control unit configured to keep said charging control unit in said halting state until it is detected that said connector receives said electric power in a case where connection of said coupler and said connector is detected, and configured to switch said charging control unit from said halting state to said operating state when it is detected that said connector receives said electric power; characterized by an informing unit (211, 43) mounted on said vehicle and configured to give information that said connector and said coupler are connected and information that said electric power is input to said connector, by operating in a first pattern in accordance with a first signal indicating connection of said coupler to said connector, and by operating in a second pattern in accordance with a second signal indicating reception of said electric power by said connector; a signal transmission unit configured to transmit said first signal while said coupler is connected to said connector; and a signal selection unit configured to: (i) receive said first signal and said second signal (SIG1, SIG2); (ii) output, while said signal selection unit receives said second signal, said second signal as received to said informing unit (211, 43) regardless of whether said signal selection unit receives said first signal, and (iii) output, while said signal selection unit receives said first signal and does not receive said second signal, said first signal to said informing unit (211, 43), wherein said activation control unit is configured to transmit said second signal while said charging control unit is in said operating state. a connector provided to said vehicle and configured such that said coupler is connectable to the connector; a power feeding unit mounted on said vehicle and configured to transmit said electric power from said connector to said power storage device; a charging control unit mounted on said vehicle, configured to charge said power storage device by controlling said power feeding unit while the charging control unit is in an operating state, and configured to halt control of said power feeding unit while the charging control unit is in a halting state; and an activation control unit configured to keep said charging control unit in said halting state until it is detected that said connector receives said electric power in a case where connection of said coupler and said connector is detected, and configured to switch said charging control unit from said halting state to said operating state when it is detected that said connector receives said electric power; characterized by an informing unit (211, 43) mounted on said vehicle and configured to give information that said connector and said coupler are connected and information that said electric power is input to said connector, by operating in a first pattern in accordance with a first signal indicating connection of said coupler to said connector, and by operating in a second pattern in accordance with a second signal indicating reception of said electric power by said connector; a signal transmission unit configured to transmit said first signal while said coupler is connected to said connector; and a signal selection unit configured to: (i) receive said first signal and said second signal (SIG1, SIG2); (ii) output, while said signal selection unit receives said second signal, said second signal as received to said informing unit (211, 43) regardless of whether said signal selection unit receives said first signal, and (iii) output, while said signal selection unit receives said first signal and does not receive said second signal, said first signal to said informing unit (211, 43), wherein (i) receive said first signal and said second signal (SIG1, SIG2); (ii) output, while said signal selection unit receives said second signal, said second signal as received to said informing unit (211, 43) regardless of whether said signal selection unit receives said first signal, and (iii) output, while said signal selection unit receives said first signal and does not receive said second signal, said first signal to said informing unit (211, 43), wherein said activation control unit is configured to transmit said second signal while said charging control unit is in said operating state.
