a state information acquisition unit configured to acquire state information of the stationary battery charger via the charging cable; and

a communication unit configured to transmit the state information to outside immediately or periodically in accordance with a situation,

wherein when the state information acquisition unit acquires abnormality information indicating an abnormality of the stationary battery charger for a first time, the communication unit transmits the abnormality information to the outside immediately, and when the state information acquisition unit acquires the abnormality information from a second time, the communication unit transmits the abnormality information to the outside periodically.

4. The storage battery type vehicle according to claim 1 further comprising an information addition unit configured to add additional information to the state information.

5. The storage battery type vehicle according to claim 4, wherein the additional information is position information of the vehicle.

6. The storage battery type vehicle according to claim 4, wherein the additional information is time information of time of occurrence of abnormality of the stationary battery charger.

7. The storage battery type vehicle according to claim 1, wherein the state information includes identification information of the stationary battery charger.

8. The storage battery type vehicle according to claim 4, wherein the additional information is operating time and/or charging time of the vehicle.

11. A charge management system comprising a management server configured to manage one or more the stationary battery chargers and one or more the storage battery type vehicles according to claim 1,

wherein the outside is the management server, and

wherein the one or more storage battery type vehicles and the management server are connected via a network,

wherein the one or more storage battery type vehicles comprises an output unit configured to output the state information,

wherein the management server comprises a management communication unit,

wherein the management communication unit of the management server notifies the state information to the one or more storage battery type vehicles that are other than the storage battery type vehicle that has transmitted the state information and are connected to the network, and

wherein the storage battery type vehicle that has received the state information from the management server outputs the received information to the output unit.

12. The charge management system according to claim 11, wherein the state information is abnormality information of the stationary battery charger and is information to which one of more pieces of information of position information of the storage battery type vehicle that has acquired the state information, time information of time of occurrence of abnormality of the stationary battery charger, operating time of the storage battery type vehicle, charging time of the storage battery type vehicle, and identification information of the stationary battery charger are added.

13. The charge management system according to claim 11,

wherein, upon receiving state information indicating restoration of the stationary battery charger, the management server notifies the one or more storage batter type vehicles of the state information indicating the restoration, and

wherein the storage battery type vehicle that has received the state information indicating the restoration from the management server outputs the received state information indicating the restoration to the output unit.

14. A charge management method

comprising a management server configured to manage the one or more stationary battery chargers and one or more the storage battery type vehicles according to claim 1,

wherein the outside is the management server, and

wherein the one or more storage battery type vehicles and the management server are connected via a network,

wherein the one or more storage battery type vehicles output the state information to the one or more stationary battery chargers and the one or more storage battery type vehicles,

wherein the management server notifies the state information to the one or more storage battery type vehicles that are other than the storage battery type vehicle that has transmitted the state information and are connected to the network, and

wherein the storage battery type vehicle that has received the state information from the management server outputs the received information to inside of the storage battery type vehicle.

2. A storage battery type vehicle

configured to charge a storage battery mounted on a vehicle via a charging cable connecting the vehicle to a stationary battery charger fixed outside the vehicle, the storage battery type vehicle comprising:

a state information acquisition unit configured to acquire state information of the stationary battery charger via the charging cable; and

a communication unit configured to transmit the state information to outside immediately or periodically in accordance with a situation,

wherein when an abnormality level of abnormality information indicating an abnormality of the stationary battery charger acquired by the state information acquisition unit is high, the communication unit transmits the abnormality information to the outside immediately, and when the abnormality level of the abnormality information acquired by the state information acquisition unit is low, the communication unit transmits the abnormality information to the outside periodically.

3. A storage battery type vehicle configured to charge a storage battery mounted on a vehicle via a charging cable connecting the vehicle to a stationary battery charger fixed outside the vehicle, the storage battery type vehicle comprising:

a state information acquisition unit configured to acquire state information of the stationary battery charger via the charging cable; and

a communication unit configured to transmit the state information to outside immediately or periodically in accordance with a situation,
