Description

  The present invention relates to a charging device that charges a vehicle including a power storage unit from the outside.

  In recent years, awareness of environmental protection has increased, and the number of hybrid vehicles and electric vehicles that can reduce emissions of global warming substances has increased. When the remaining amount of charge in the power storage unit decreases, there is a risk that the hybrid vehicle or the electric vehicle may decrease the power performance of the vehicle or become unable to run. In recent years, supported by an increase in the number of hybrid vehicles and electric vehicles used, it has been studied to install a charging device for charging a vehicle including a power storage unit from the outside in a stand or a general garage.

  The charging device, for example, connects a connector to a car and charges the power storage unit of the car, but unlike the case of refueling a gasoline automobile, it takes time (for example, 5 to 6 hours) to charge the power storage unit with an optimal amount of power. ). Therefore, the user of an automobile may leave the automobile after starting charging. In this case, when the user of the car is away from the car, a third party pulls out the connector from the car and connects it to the power storage unit of his / her car without permission. When charging is complete, connect the connector to the user's car. It may be possible to steal power by correcting it.

  On the other hand, it is conceivable that a mechanism for preventing the connector of the charging device connected to the vehicle from coming off is provided in the vehicle so that a third party cannot arbitrarily disconnect the connector of the charging device from the vehicle after the start of charging. However, this technology cannot prevent theft of electric power for vehicles that do not have a connector removal prevention mechanism. Further, providing a connector removal prevention mechanism in each automobile leads to an increase in the cost of the automobile. Therefore, it is desirable to provide a power theft countermeasure on the charging device side.

  In this regard, for example, in Patent Document 1, after authenticating the user normally and starting charging, if it is detected that the vehicle and the connector of the charging device are changed from the connected state to the disconnected state during the charging, the charging is stopped. The technology to reset the person identification information is proposed. According to this, even if the third party pulls out the connector of the charging device from another person's car and connects to his car, the third party cannot charge until the identity authentication is completed, and the power cannot be stolen (for example, , See Patent Document 1).

JP 2007-228695 A

  However, in the conventional charging device, the user of the automobile cannot know that the charging is interrupted by disconnecting the connector from the charging device until the user voluntarily returns to the automobile. Therefore, even if the user of the car returns to the car, the car may not be able to leave because charging is incomplete. In this case, even if the user connects the connector to the automobile and resumes charging, as described above, charging takes time, so that it takes time until recharging is completed. In order to avoid this problem in the conventional charging apparatus, users of the automobile may check the connection state between the automobile and the power supply unit frequently, but this is not realistic. As described above, the conventional charging device causes a time loss in recharging when the connector is detached from the automobile.

  The present invention has been made in order to solve the above-described problems, and prevents theft of power, and the time loss of recharging when the power supply unit and the vehicle are changed from the connected state to the disconnected state. An object of the present invention is to provide a charging device that can reduce the battery power.

The charging device according to the present invention has the following configuration.
(1) In a charging device that connects an electric power supply unit to a vehicle including a power storage unit and supplies electric power to the vehicle from the electric power supply unit to perform charging, the vehicle and the electric power supply unit are in a disconnected state from a connected state. When it is detected that the vehicle has been connected, the vehicle user or the charging device manager is notified of the fact that the vehicle and the power supply unit are in a disconnected state.

(2) In the invention described in (1), the information processing apparatus includes an authentication unit that authenticates that the user identification information is normal, and the notification unit uses the vehicle acquired when the authentication unit performs authentication. Notification to the notification destination of the user or the administrator of the charging device.

(3) In the invention described in (1) or (2), an input unit for inputting power supply conditions when power is supplied to the vehicle, and the power supply unit and the vehicle are changed from a connected state to a disconnected state. When the connection unit is detected again, the authentication unit is instructed to authenticate the user identification information. When the authentication unit authenticates that the user identification information is normal, And a power supply control unit that resumes charging under the input power supply conditions.

(4) In the invention according to any one of (1) to (3), the authentication unit may enter, as the user identification information, a personal identification number or a credit input when the power supply condition is input. Card identification information or identification information of an ETC card mounted on the vehicle is used.

  The charging device having the above configuration detects that the power supply unit and the vehicle are changed from the connected state to the disconnected state, and the vehicle and the power supply unit are disconnected from the user or the administrator. Notify that. According to such a charging apparatus, the time loss of recharging can be reduced when the power supply unit and the vehicle are switched from the connected state to the disconnected state while preventing the power from being stolen.

  Further, when the charging device detects that the power supply unit and the vehicle are connected again, the charging unit authenticates whether or not the user identification information is normal, and the user identification information is normal. When authenticated, charging is resumed under the power supply conditions input to the input unit. According to such a charging apparatus, it is not necessary to re-input the power supply condition to the input unit when resuming the charging, and the time loss when the user or the manager resumes the charging can be reduced. .

  Next, an embodiment of a charging device according to the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing configurations of a vehicle 100 and a charging device 200 according to the first embodiment of the present invention.
The vehicle 100 includes a wheel 108, a motor 106 that drives the wheel 108, an inverter 104 that supplies three-phase AC power to the motor 106, and a main battery 102 (an example of “power storage unit”) that supplies DC power to the inverter 104. including. That is, the vehicle 100 is an electric vehicle, but the present invention is also applied to a vehicle powered by the electric power stored in the main battery 102, such as a hybrid vehicle or an electric motorcycle that uses a motor and an engine for driving. Can do.

  Vehicle 100 has a configuration in which main battery 102 can be charged from the outside. That is, vehicle 100 further includes a connector 124, a charging AC / DC conversion unit 110, a switch 122, a connector connection detection unit 120, a communication unit 116, and a control ECU 114.

  The connector 124 is provided with a terminal for supplying a commercial power source such as AC 100 V from the outside. The charging AC / DC conversion unit 110 converts AC power supplied to the connector 124 into DC power and supplies it to the main battery 102. The switch 122 connects the connector 124 and the charging AC / DC conversion unit 110. The connector connection detection unit 120 detects that the connector 206 (an example of “power supply unit”) of the charging device 200 is connected to the connector 124. The communication unit 116 controls communication with the communication unit 210 of the charging device 200.

  The control ECU 114 monitors the SOC (State Of Charge) of the main battery 102, and detects connector connection by the connector connection detection unit 120. When the connector 206 is connected to the connector 124 and the SOC is lower than a predetermined value (control center), the control ECU 114 switches the switch 122 from OFF to ON and operates the charging AC / DC converter 110. The main battery 102 is charged.

  Here, it is desirable to use the main battery 102 in the SOC near the control center. In general, the control center can be set to an arbitrary value. If the SOC is close to 100%, the electric power collected by the vehicle 100 before and after traveling cannot be stored in the main battery 102, and the energy use efficiency decreases. Further, if the SOC of the main battery 102 is too low (for example, less than 20%), the power required by the vehicle 100 before and after the start of traveling cannot be sufficiently supplied, and the power performance of the vehicle 100 may be reduced. For this reason, it is preferable that the state of charge of the battery is controlled in the vicinity of the control center with a margin for charging and discharging of the main battery 102. For example, when the usage area of the main battery 102 is SOC 20% to 90%, it is preferable to set the SOC at the control center to about 40% to 60%. The state of charge of the main battery 102 can also be grasped by means for monitoring the voltage of the main battery 102.

  When charging the main battery 102, the control ECU 114 requests the charging device 200 to charge via the communication unit 116. In this case, the control ECU 114 may calculate the optimum charge amount from the SOC of the main battery 102 and specify the optimum charge amount to make a charge request. Alternatively, the SOC may be transmitted from the control ECU 114 to the charging device 200 side via the communication unit 116, the optimum charging amount may be calculated based on the SOC on the charging device 200 side, and the start of charging may be determined.

  The charging device 200 is a communication unit 210, a card recognition unit 212, a registration information database 214, an AC power source 202, a charging cable 218, a connector 206, and a communication that receives information such as an SOC and a charging request from the vehicle 100 side. Unit 210, switch 204, and control ECU 208 (an example of “authentication unit”, “notification unit”, and “power supply control unit”).

  The card recognition unit 212 recognizes the card 216 on which user identification information for identifying the user of the charging device 200 is recorded. The registration information database 214 is registered with user identification information of the charging device 200. The connector 206 is provided at the end of the charging cable 218. The switch 204 connects the AC power source 202 to the charging cable 218. The ECU 208 performs on / off control of the switch 204.

The registration information database 214 may be provided outside the charging device 200, or the charging device 200 may perform communication to query the external database for user identification information.
The card 216 includes a membership card, a prepaid card, a credit card, and the like.

  The control ECU 208 stores an input unit 222 for inputting power supply conditions (fixed charge mode, fixed charge mode, full charge mode) for supplying power to the vehicle, and the power supply conditions input to the input unit 222. A power supply condition storage unit 228 is connected.

  The control ECU 208 is inquired by the card recognition unit 212, information such as the SOC and charge request received by the communication unit 210, power supply conditions input to the input unit 222, a charge end instruction input to the charge end instruction unit 224. The switch 204 is turned on / off according to the collation result between the card 216 and the registration information database 214. The control ECU 208 displays information related to charging (for example, chargeable amount, scheduled charging completion time, charging amount, charging method, amount, etc.) on the display unit 226.

The control ECU 208 confirms whether there is a charge request from the vehicle 100 side to the charging device 200 side, and the user identification information based on the card 216 matches the regular registrant information and can be normally authenticated. When the control ECU 208 confirms the charge request and normal user authentication, the control ECU 208 turns on the switch 204 and starts charging based on the power supply conditions. On the other hand, the control ECU 114 operates the charging AC / DC conversion unit 110 to charge the main battery 102.
The user identification information includes a password entered when inputting power supply conditions, user identification information stored in a prepaid card or a membership card, user identification information using the person identification information of a credit card, etc. including.

  Control ECU 208 transmits the power supply condition to communication unit 116 of vehicle 100. The control ECU 114 determines whether or not the charging is completed based on the power supply condition received by the communication unit 116. If the charging is completed, the control ECU 114 stops the charging AC / DC converting unit 110 and turns on the switch 122. Vary from off to off. Then, the control ECU 114 requests the charging device 200 to stop charging via the communication unit 116. Then, the control ECU 208 changes the switch 204 from on to off.

  If another person removes the connector 206 from the vehicle 100 during charging or if the connector 206 is mistakenly removed from the vehicle 100, the charging device 200 resets the user identification information whose collation is confirmed and waits for the input of the card 216 again. It becomes a state.

  That is, charging device 200 that charges a vehicle having a power storage unit from the outside includes switch 204 that supplies power to vehicle 100, and control ECU 208 that instructs switch 204 to start and stop supplying power. The control ECU 208 obtains user specifying information for specifying a user who uses the charging device 200, confirms that the user specifying information is normal, and instructs the switch 204 to start supplying power. When the control ECU 208 detects that the connector 206 and the vehicle 100 have changed from the connected state to the disconnected state, the control ECU 208 instructs the switch 204 to stop supplying power and obtains the user specifying information again for resuming charging. .

  When the control ECU 208 detects that the connector 206 and the vehicle 100 are changed from the connected state to the disconnected state, the control ECU 208 connects the communication unit 210 to the mobile terminal device 300 or the like possessed by the user of the vehicle 100 or the administrator of the charging device 200. 400 is connected. Then, the control ECU 208 notifies the user or administrator that the connector 206 and the vehicle 100 have changed from the connected state to the disconnected state.

  When the control ECU 208 re-acquires the user identification information to confirm that the user identification information is normal and detects that the connector 206 and the vehicle 100 are connected again, the control ECU 208 inputs the information to the input unit 222. Charging is performed under power supply conditions.

FIG. 2 is a flowchart showing a processing structure of a charging process executed by the charging device of FIG.
First, in step 1 (hereinafter referred to as “S1”), the control ECU 208 determines whether or not the connection between the connector 206 of the charging apparatus 200 and the connector 124 of the vehicle 100 has been confirmed. This determination may be made by the control ECU 208 acquiring the result recognized by the connector connection detection unit 120 in the vehicle 100 via the communication unit 210. Alternatively, it may be determined that the connector 206 is connected by providing connection detection means on the connector 206, which indicates that a switch or the like that conducts when the protrusion is pushed in is connected. The control ECU 208 waits until the connection is confirmed (S1: No).

  Next, when the control ECU 208 confirms the connection (S1: Yes), the chargeable amount is displayed on the display unit 226 in S2. Control ECU 208 calculates a chargeable amount based on the SOC received from vehicle 100 by communication unit 210.

  Then, the control ECU 208 performs authentication based on the card 216 inserted in the card recognition unit 212, and determines whether there is a problem with the card authentication. In other words, the control ECU 208 uses the ID information read from the card 216 by the card recognition unit 212, the personal identification number input when the card is inserted, and the personal identification information of the credit card as user identification information, and is stored in the registration information database 214. The acquired user identification information is collated with the existing user identification information. If the acquired user identification information (ID information, personal identification number, identification information, etc.) does not match the user identification information in the registration information database 214, it is determined that there is a problem with the card authentication (S3: No), The process ends.

  On the other hand, if the acquired user identification information matches the user identification information in the registration information database 214 and it is determined that there is no problem in card authentication (S3: Yes), the user identification information is normal. Determine and proceed to S4. In S <b> 4, it is determined whether any of a fixed amount, a fixed amount, or full charge, which is an example of the power supply condition, is input to the input unit 222 and is instructed to be selected. Here, "Fixed amount" is a charging mode that charges up to a specified charge, "Fixed amount" is a charging mode that charges up to a specified amount of charge, and "Full charge" is a charging mode that charges up to an optimal amount of charge. It is. The control ECU 208 waits until it is recognized that the selection of the power supply condition has been completed by pressing a button for notifying the end of the input of the power supply condition (S5: No).

  When the selection of the power supply condition is completed (S5: Yes), the control ECU 208 starts charging in S6 under the selected power supply condition (charge mode).

  Next, in S7, the control ECU 208 confirms whether the connector 206 of the charging apparatus 200 is disconnected from the connector 124 of the vehicle 100 before the charging is completed. The connection state between the connector 206 and the vehicle 100 is confirmed in the same manner as S1.

  When connector 206 of charging device 200 is not disconnected from connector 124 of vehicle 100 (S7: Yes), control ECU 208 determines in S8 whether or not charging is completed. The control ECU 208 determines whether or not charging has been completed based on whether or not the control ECU 114 of the vehicle 100 has received a charging stop instruction requested to the charging device 200 when charging is completed so as to satisfy the power supply condition. to decide.

  The control ECU 208 determines that the charging is not completed when the vehicle 100 is requested to stop charging (S8: No), returns to S7, the connector 206 of the charging device 200, the connector 124 of the vehicle 100, and so on. Recheck the connection status of.

  If the vehicle 206 is requested to stop charging without the connector 206 of the charging device 200 being disconnected from the connector 124 of the vehicle 100, the control ECU 208 determines that charging has been completed (S8: Yes), and S9. Then, the power supply condition storage unit 228 is reset. Then, the control ECU 208 ends the charging mode in S10. That is, the control ECU 208 switches the switch 204 from on to off and stops charging the vehicle 100. The control ECU 114 also switches the switch 122 from on to off, and stops charging the main battery 102. Thereafter, the control ECU 208 ends the process.

  In contrast, if the connector 206 of the charging device 200 is disconnected from the connector 124 of the vehicle 100 before receiving the charge stop request from the vehicle 100 (S7: No), the control ECU 208 switches the switch at S11. Switch 204 from on to off. Thereby, the charging mode is interrupted.

  Next, in S12, the control ECU 208 determines whether or not a charge end instruction is input to the charge end instruction unit 224. For example, when the user wants to use the vehicle 100 in an emergency before the scheduled charging completion time, or when the amount displayed on the display unit 226 exceeds the budget, the user instructs the charging end instruction unit 224 to end charging. The charging can be forcibly terminated by inputting. When the charging end instruction is input to the charging end instruction unit 224 as described above (S12: Yes), the power supply condition storage unit 228 is reset in S9. And control ECU208 complete | finishes a process, after complete | finishing charge mode in S10.

  On the other hand, when the charge end instruction is not input to the charge end instruction unit 224 (S12: No), the control ECU 208 notifies in S13. That is, the control ECU 208 notifies the portable terminal device 300 possessed by the user or administrator that the connectors 206 and 124 have been changed from the connected state to the disconnected state from the communication unit 210 via the network 400. Here, the notification destination for notifying that the connection state is changed to the non-connection state can be changed to an arbitrary third party by separately setting.

  Next, in S14, control ECU 208 determines whether or not connector 206 of charging device 200 is reconnected to connector 124 of vehicle 100. The reconnection is determined by the control ECU 208 in the same manner as in S1. When it is determined that reconnection is not performed (S14: No), it is determined in S15 whether or not a predetermined time has elapsed. Here, the “certain time” is an allowable time from when the user or the administrator receives the notification until the connector 206 is reconnected to the vehicle 100. If the connector 206 is not reconnected to the vehicle 100 after a certain period of time, the user or the administrator has no intention of recharging, or the user or the administrator inputs a charge end instruction to the charge end instruction unit 224. This is because it is thought that he forgot to do it. Until a predetermined time elapses (S15: No), the process returns to S14 to monitor whether or not the connection is reestablished.

  If the predetermined time has passed without the connector 206 being reconnected to the connector 124 of the vehicle 100 (S15: Yes), the control ECU 208 resets the power supply condition storage unit 228 in S9, and then ends the charging mode in S10. Then, the process ends.

  On the other hand, when the control ECU 208 confirms that the connector 206 is reconnected to the connector 124 of the vehicle 100 (S14: Yes), there is a problem in the re-authentication of the card 216 inserted into the card recognition unit 212 in S16. Determine if there is. The card re-authentication step is performed in the same manner as S3.

  For example, a third party removes the connector 206 of the charging device 200 from the vehicle 100 and connects it to his / her vehicle without permission, or after connecting the connector 206 to his / her vehicle without permission. Is inserted. In this case, the control ECU 208 determines that there is a problem with the card re-authentication because the user identification information cannot be normally authenticated (S16: No), and returns to S14.

  In this way, even if the connector 206 is removed during charging and another person tries to charge another vehicle, it is necessary to input the user identification information again. There is no charge and theft of power can be prevented.

  On the other hand, for example, when the user or the administrator inserts the card 216 into the card recognition unit 212 and the control ECU 208 determines that there is no problem with the card re-authentication (S16: Yes), the control ECU 208 In S17, the charging mode is resumed. The resumption of the charging mode is performed by the control ECU 208 switching the switch 204 from off to on and transmitting the power supply conditions stored in the power supply condition storage unit 228 to the vehicle 100. The vehicle 100 is charged under the same power supply condition as before the charging interruption because the power supply condition newly received from the charging device 200 is the same as the power supply condition received before the charging interruption.

  Thereafter, the control ECU 208 returns to S7 and performs charging while monitoring the connection state between the connector 206 of the charging apparatus 200 and the connector 124 of the vehicle 100. Since the processing after S7 is as described above, the description thereof is omitted.

  Here, the control ECU 208 does not immediately end the charging mode when a third party fails to resume charging (S16: No). Therefore, even if charging resumption fails, the control ECU 208 inputs the power requirement condition if the user or the manager connects the connector 206 to the connector 124 of the vehicle 100 within a certain time and there is no problem with the card re-authentication. Charging can be resumed without causing the unit 222 to re-input the power supply conditions.

  When the processing shown in FIG. 2 is completed, the control ECU 208 transmits the amount of charge to the vehicle 100 to a charging device (not shown) provided inside or outside, and charges the used power.

Next, the effect of the charging device 200 will be described.
A user or a manager (for example, a clerk at a charging station) connects the connector 206 of the charging device 200 to the connector 124 of the vehicle 100 and inputs power supply conditions to the input unit 222. When charging device 200 authenticates that the personal identification number input by control ECU 208 or the user identification information using the identification information on the credit card is normal, power is supplied from connector 206 to vehicle 100 for charging. Start. Since charging takes a long time, the user may leave the vehicle with the card 216 after confirming that charging has started. At that time, for example, a third party may disconnect the connector 206 of the charging device 200 from the vehicle 100, or the connector 206 may be accidentally disconnected from the vehicle 100 by an animal or a human being. In this case, the control ECU 208 detects that the connector 206 and the vehicle 100 are switched from the connected state to the disconnected state, and the vehicle 100 and the connector 206 are disconnected from the user or the administrator. To be notified. The user or administrator who has received the notification goes to the vehicle 100 or asks another person to go to the vehicle 100, reconnects the connector 206 to the vehicle 100, and resumes charging.

  As described above, even when the user or the manager is away from the charging device, the user or the manager knows that the connector 206 has been disconnected from the vehicle 100 by the notification, and reconnects the connector 206 to the vehicle 100. Therefore, if a third party pulls out the connector 206 being charged from the vehicle 100, the user or administrator is afraid of coming to the vehicle 100, and it is difficult to steal the power. Further, since charging device 200 restarts charging at an early stage, charging device 200 can charge main battery 102 so as to obtain sufficient power performance for traveling. Therefore, the charging device 200 according to the first embodiment can reduce the time loss of recharging when the connector 206 and the vehicle 100 change from the connected state to the disconnected state while preventing the power from being stolen.

Further, for example, even when a plurality of people share one vehicle 100, the charging device 200 is connected to the notification destination of the user or the administrator acquired when the control ECU 208 performs authentication. Notify that the connection has been disconnected. As a result, the responsibility for completing charging is clarified, so that it is possible to avoid a problem that the next vehicle user suffers due to insufficient charging.
Further, for example, it is assumed that the card 216 is a credit card, and the control ECU 208 uses the person identification information of the credit card 216 as the user identification information. In this case, it is preferable to store the notification destination of the user or the administrator in the credit card and acquire the notification destination from the card 216 when the control ECU 208 performs card authentication. Accordingly, the charging device 200 does not need to store and manage the notification destination of the user or administrator in the memory, and can protect personal information.

  When the charging device 200 detects that the connector 206 and the vehicle 100 are connected again, the charging device 200 causes the control ECU 208 to authenticate whether or not the user identification information is normal. When the control ECU 208 authenticates that the user identification information is normal, the charging device 200 resumes charging under the power supply conditions input to the input unit 222. Therefore, according to the charging device 200, it is not necessary to re-input the power supply condition to the input unit 222 when resuming charging, and the user of the vehicle 100, the administrator of the charging device 200, and the like Time loss can be reduced.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 3 is a block diagram illustrating configurations of the vehicle 100A and the charging device 200A according to the second embodiment of the present invention.
The vehicle 100A and the charging device 200A according to the second embodiment are different from those according to the first embodiment in an authentication method of user identification information and a notification method of a disconnected state between the connector 206 and the vehicle 100A. Therefore, here, it demonstrates centering on a different point from 1st Embodiment, and a common point uses the same code | symbol as 1st Embodiment for drawing, and abbreviate | omits description suitably.

  The charging device 200A of the second embodiment causes the vehicle 100A to acquire user specifying information. That is, in the vehicle 100A, the ETC card recognition unit 132 is connected to the control ECU 114A, and the control ECU 114A transmits the ID (person identification information) acquired by the ETC card recognition unit 132 from the ETC card 134 to the charging device 200A.

  The charging device 200A is communicably connected to the management device 500 via a network 400 such as the Internet, and constructs a charging system. A plurality of charging devices 200 </ b> A are connected to the management device 500. The management apparatus 500 includes a registration information database 504 that stores user identification information, and a notification destination storage unit 502 that stores a notification destination for each user registered in the registration information database 504. The notification destination and the user identification information Are managed collectively.

  When the control ECU 208A acquires the ID of the ETC card 134 from the vehicle 100, is there any user identification information that matches the ID acquired in the registration information database 504 by connecting the communication unit 210A to the management device 500 via the network 400? Inquire. If the control ECU 208A can confirm that there is user identification information that matches the acquired ID in the registration information database 504, the control ECU 208A determines that the ID has been successfully authenticated.

  Control ECU 208A, when connector 206 is connected to connector 124 of vehicle 100A and acquires an ID from vehicle 100A via communication unit 210A, collates the acquired ID with registration information database 214. And control ECU208A will start charge, if ID is normally authenticated.

  The control ECU 208 </ b> A acquires the notification destination acquired from the ETC card 134 by the control ECU 114 </ b> A via the ETC card recognition unit 132 from the vehicle 100. When the control ECU 208 </ b> A detects that the connector 206 and the vehicle 100 </ b> A have changed from the connected state to the disconnected state, the control ECU 208 </ b> A transmits the ID and the disconnected information from the communication unit 210 </ b> A to the management device 500 via the network 400. The management device 500 searches the notification destination storage unit 502 for a notification destination corresponding to the ID received from the charging device 200A, and the connector 206 and the vehicle 100A are included in the searched notification destination (number or email address of the mobile terminal device 300). Notify that the connection has been disconnected.

  Control ECU 208A causes switch 204 to transition from off to on when connector 206 is reconnected to vehicle 100A. Vehicle 100A receives supply of power from charging device 200A in accordance with the power supply conditions received from charging device 200A at the start of charging. Therefore, vehicle 100A restarts charging under the same power supply conditions as before charging interruption.

As described above, in the charging device 200 </ b> A of the second embodiment, the management device 500 collectively manages contact information and user identification information. Therefore, if the charging device 200A registers the user identification information in the registration information database 502, the user can charge the vehicle 100A using a charging device installed in another place.
In addition, since the notification destination and user identification information are collectively managed in the management apparatus 500, personal information is not easily stolen.

In addition, although embodiment of this invention was described, this invention is not limited to the said embodiment, A various application is possible.
For example, in the above embodiment, the authentication unit authenticates the user specifying information stored in a card such as a credit card, an ETC card, a prepaid card, or a membership card. On the other hand, an IC tag storing user identification information may be attached to the vehicle, and the IC tag of the vehicle mounted on the charging device and the authentication unit may perform wireless communication to perform authentication. In this case, the vehicle information stored in the IC tag may be used as the user specifying information.
For example, the notification destination is stored in the ETC card 134, and when the connector 126 is removed from the vehicle 100A during charging, the control ECU 208A acquires and acquires the contact information stored in the ETC card 134 from the vehicle 100. You may make it notify to a contact address.
