  However, there may be situations where charging facilities are not available in some areas due to power outages. In such a case, the conventional system may guide the occupant to the charging facility where the failure has occurred (the battery cannot be charged). Recently, in order to promote the spread of electric vehicles, plug-in hybrid vehicles, etc., infrastructures such as charging stations for charging batteries are rapidly being established, but the number of charging stations is still gasoline. Much less than a stand. Therefore, the vehicle guided to the charging station where the failure has occurred needs to go to another charging station, but the remaining capacity of the battery is long due to the long installation interval of the charging station (distance to the adjacent charging station). Depending on the situation, it may not be possible to travel to another charging station. In addition, since it is not known in which charging station the battery can be charged, there is a possibility of going to a charging station in the same power outage area.

A plurality of charging stations 40 arranged in the vicinity of the target vehicle are extracted from the charging stations 40 other than the area where the power failure occurs. In this case, a plurality of charging stations 40 arranged in the vicinity of the target vehicle are extracted in order from the target vehicle.

  The charging infrastructure information providing apparatus 200 sequentially transmits the station usage status information indicating the current usage status and reservation status at each charging station 40, and stores the transmitted latest station usage status information in the storage unit 280. . The alternative stand extraction unit 214 refers to the latest stand usage status information stored in the storage unit 280, and starts charging quickly based on the travel time and the waiting time required to reach the charging stand 40. A list of charging stations 40 is created in the order that can be made.

  The alternative station information transmission unit 215 displays, for each target vehicle extracted by the vehicle extraction unit 213, alternative charging station information representing the list of charging stations 40 extracted by the alternative station extraction unit 214, and includes a power failure failure area. Is transmitted to the in-vehicle navigation device 300 via the communication control unit 270.

  The charging trouble information acquisition unit 216 acquires charging trouble information transmitted from the charger 50 and the in-vehicle navigation device 300 when the battery charging of the electric vehicle 100 becomes unsuccessful at the charging stand 40. The charging trouble information is configured to discriminate between a vehicle-side trouble that makes charging impossible due to the electric vehicle 100 side and a stand-side trouble that makes charging impossible due to the charging stand 40 side. For example, the vehicle information of the electric vehicle 100 in which the charging abnormality has occurred, and the charging station information in which the power feeding abnormality has occurred in the case of a stand-side trouble.

  The vehicle-side trouble processing unit 217 operates when charging trouble information representing a vehicle-side trouble is supplied to the charging trouble information acquisition unit 216. The charging trouble information transmission unit 314 of the in-vehicle navigation device 300 uses the vehicle information (registration number, manufacturer, position, etc.) of the electric vehicle 100 as charging trouble information indicating that a charging trouble has occurred in the electric vehicle 100. Send. The vehicle-side trouble processing unit 217 transmits notification information for guiding the vehicle to the nearby vehicle dealer 85 to the in-vehicle navigation device 300 based on the transmitted charging trouble information. That is, the vehicle-side trouble processing unit 217 refers to the data stored in the storage unit 280 and extracts the vehicle dealer 85 closest to the vehicle from the plurality of vehicle dealers 85 that handle the vehicle type of the vehicle. The vehicle dealer information (name, address, telephone number, URL, etc.) specifying the extracted vehicle dealer 85 is transmitted to the in-vehicle navigation device 300. The vehicle-side trouble processing unit 217 also transmits the registration number and position information of the vehicle to the vehicle dealer 85.

  The stand side trouble processing unit 218 operates when charging trouble information representing a charging stand side trouble is supplied to the charging trouble information acquisition unit 216. The power supply ECU 60 of the charger 50 includes, as charging trouble information indicating that a charging trouble has occurred at the charging stand 40, charging station information of the charging stand 40 (name, location of the charging stand 40, manufacturer of the charger 50, charger). 50 product numbers, numbers identifying the charger 50 at the charging station 40, etc.). Based on the charging station information, the stand-side trouble processing unit 218 transmits a notification indicating that a charging trouble has occurred in the charging station 40 and information on the charging station 40 to the charging station supplier company 30. To do.

  Next, charging infrastructure information provision processing performed by the charging infrastructure information provision apparatus 200 will be described. FIG. 8 shows a charging infrastructure information provision routine executed by the main control unit 210 of the charging infrastructure information provision apparatus 200. This charging infrastructure information provision routine is repeatedly executed at a predetermined cycle.

  When the charging infrastructure information provision routine starts, first, the charging infrastructure information provision apparatus 200 acquires power supply state information in the smart grid in step S11. Specifically, current power failure information provided by the power company 10 is read via the communication control unit 270, and measurement data transmitted from the smart meter 80 provided for each consumer is read. The power supply state information may be either current power outage information provided by the power company 10 or measurement data of the smart meter 80. Further, the measurement data of the smart meter 80 may be read only from the measurement data of the smart meter 80 provided in each charging station 40.

  Subsequently, in step S12, charging infrastructure information providing apparatus 200 determines whether a power outage has occurred in the smart grid based on the power outage information provided by power company 10 and the measurement data of smart meter 80. If there is no power outage (S12: No), this routine is temporarily terminated.

  This routine is repeated at a predetermined cycle. Therefore, the power supply state in the smart grid is repeatedly detected. When the occurrence of a power failure is detected (S12: Yes), in the subsequent step S13, a district where the power failure has occurred (hereinafter referred to as a power failure failure district) is extracted. The power failure information provided by the power company 10 identifies the power system region where the power failure has occurred. For example, in FIG. 1, region A is a power outage failure occurrence region. Therefore, it is possible to grasp the power failure failure area based on the power failure information.

  Further, the charging infrastructure information providing apparatus 200 grasps the power failure failure area based on the measurement data of the smart meter 80 and adds it to the power failure failure area obtained from the power failure information provided by the power company 10. In this case, when a power failure occurs only in a specific charging station 40, the specific charging station 40 is handled as a power failure failure area.

  The processes in steps S11 to S13 are processes executed by the infrastructure failure information acquisition unit 211.

  Subsequently, in step S14, the charging infrastructure information providing apparatus 200 is connected to the electric vehicle 100 existing in the power outage failure occurrence area and the electric power that exists in the adjacent area adjacent to the power outage failure occurrence area and heads toward the power outage failure occurrence area. The vehicle 100 is extracted. This process is a process executed by the vehicle information acquisition unit 212 and the vehicle extraction unit 213. In step S14, the target vehicle is extracted based on the vehicle position and the traveling direction of the vehicle included in the vehicle information sequentially transmitted to the charging infrastructure information providing apparatus 200.

  Subsequently, in step S15, charging infrastructure information providing apparatus 200, for each of the extracted target vehicles, in the vicinity of the target vehicle among charging stations 40 (charging station 40 that has not been out of power) other than the power outage failure area. The charging station 40 maintained at the position is extracted. In this case, a plurality of charging stations 40 maintained in the vicinity of the target vehicle are extracted. Since the extracted charging station 40 is an alternative to the charging station 40 in the area where the power failure occurs, the extracted charging station 40 is hereinafter referred to as an alternative charging station 40.

  Further, the convenience of the charging stand 40 depends on the waiting time. Therefore, when extracting the charging station 40, the waiting time and the reservation time of the charging station 40 are acquired with reference to the stand usage status information (including waiting time information and reservation time information). Then, a list of alternative charging stations 40 is created in the order in which charging can be started substantially early. For example, a list of alternative charging stations 40 is created in the order of the shortest total time of the time required to reach the charging station 40 (distance from the host vehicle to the charging station 40 / estimated vehicle speed) and the waiting time required after arrival. To do. The alternative charging station 40 may be further extracted from the charging station 40 installed in the traveling direction based on the traveling direction information of the electric vehicle 100.

  The process of step S15 is a process executed by the alternative stand extraction unit 214.

  Subsequently, charging infrastructure information providing apparatus 200 transmits charging infrastructure information to in-vehicle navigation apparatus 300 in step S16. The charging infrastructure information includes alternative charging station information that represents a list of alternative charging stations 40, and power failure failure occurrence area information that represents a power failure failure occurrence area. Also, the alternative charging station information is created by referring to the charging station information stored in the storage unit 280, and the name, location, waiting time, surrounding facility status, and charger type of the listed alternative charging station 40 ( Normal charging / rapid charging). The process of step S16 is a process executed by the alternative stand information transmission unit 215.

  When charging infrastructure information is transmitted in step S16, charging infrastructure information providing apparatus 200 once ends the charging infrastructure information providing routine, and repeats the above-described processing at a predetermined cycle. Therefore, according to this charging infrastructure information provision routine, an appropriate target vehicle corresponding to the power outage failure occurrence area is always extracted, and appropriate alternative charging station information is transmitted to the target vehicle. .

  Next, the charging infrastructure information notification process performed by the vehicle-mounted navigation device 300 will be described. FIG. 9 shows a charging infrastructure information notification routine executed by the charging infrastructure information notification unit 313 of the in-vehicle navigation device 300. This charging infrastructure information notification routine is repeatedly executed at a predetermined cycle.

  When the charging infrastructure information notification routine starts, first, the charging infrastructure information notification unit 313 determines whether or not charging infrastructure information has been received in step S21. If the charging infrastructure information has not been received, this routine is temporarily terminated. This routine is repeated at a predetermined cycle. Therefore, it waits until charging infrastructure information is transmitted.

  When charging infrastructure information is transmitted from charging infrastructure information providing apparatus 200 to wireless communication control unit 370 of in-vehicle navigation device 300 (S21: Yes), the received charging infrastructure information is stored in storage unit 390 in step S22. Subsequently, in step S23, as shown in FIG. 10, a message indicating that a power failure has occurred and a list of alternative charging stations 40 are displayed on the display unit 350.

  In this list, not only the name of the alternative charging stand 40 but also the distance from the own vehicle to the alternative charging stand 40 and the expected time until charging can be started at the alternative charging stand 40 are displayed for each alternative charging stand 40. . Further, for each alternative charging station 40, a detail button icon B1 for displaying details of the alternative charging station 40, a determination button icon B2 for setting the alternative charging station 40 as a destination, and a power outage failure occurrence area are displayed. A blackout area button icon B3 for performing and a return button icon B4 for returning to the normal map display screen are displayed.

  Subsequently, the charging infrastructure information notification unit 313 determines whether or not the detailed button icon B1 is pressed in step S24. If the detailed button icon B1 is pressed, the corresponding alternative charging stand is determined in step S25. Forty detailed information (address, surrounding facility status, charger type, reservation status, etc.) is displayed on the display unit 350. On the other hand, if the detail button icon B1 is not pressed, the process of step S25 is skipped.

  Subsequently, the charging infrastructure information notification unit 313 determines whether or not the power failure area button icon B3 is pressed in step S26. If the power failure area button icon B3 is pressed, the display unit 350 is determined in step S27. A map is displayed on the display screen, and the map display screen is displayed in a color-coded manner so that the power failure failure area can be distinguished from other normal areas. In this case, it is preferable to change the display image so that the occupant knows that the display mark of the charging station 40 existing in the power outage failure occurrence area cannot be used with a mark. On the other hand, when the power failure area button icon B3 is not pressed, the process of step S27 is skipped.

  Subsequently, the charging infrastructure information notifying unit 313 determines whether or not the determination button icon B2 is pressed in step S28. If the determination button icon B2 is pressed, the determination button icon B2 is displayed in step S29. A destination setting command for setting the pushed alternative charging station 40 as a destination is output to the navigation control unit 311. Thereby, the navigation control part 311 sets this alternative charging stand 40 as a destination, and starts route guidance. On the other hand, when the power failure area button icon B3 is not pressed, the process of step S29 is skipped.

  Subsequently, the charging infrastructure information notification unit 313 determines whether or not the return button icon B4 is pressed in step S30. If the return button icon B4 is pressed, the normal navigation display screen is displayed in step S31. The routine is terminated once. On the other hand, if the return button icon B4 is not pressed, the process proceeds to step S24 and the same process is repeated.

  This routine is repeated at a predetermined cycle. In this case, even during the period in which the loop processing from step S24 to step S30 is continued, the processing from step S21 is resumed at a predetermined cycle. Therefore, an alternative charging station list based on the latest charging infrastructure information is displayed. Note that the display screen displayed in step S25 or step S27 is provided with a return icon button, and is configured to switch to the list screen shown in FIG. 10 when the return button icon is pressed.

  According to the charging infrastructure information notification routine described above, the occupant of the target vehicle can grasp the failure status of the charging facility infrastructure in real time. Therefore, it is not necessary for the occupant to investigate the power outage occurrence situation. In addition, an appropriate alternative charging stand 40 can be selected from the navigation screen. Alternatively, the alternative charging station 40 can be set as the destination as it is from the list display screen. In addition, since the alternative charging stand 40 is listed in the order in which charging can be started earliest, the alternative charging stand 40 suitable for the passenger can be selected. Therefore, it is very convenient.

  In addition, since the infrastructure failure information is transmitted only to the electric vehicle 100 in the vicinity of the power outage failure area and is not transmitted to the electric vehicle 100 existing in the area unrelated to the power outage failure, the notification of the occurrence of the power outage failure is provided. (List display of alternative charging stand 40) does not become troublesome.

  Next, processing for a charging trouble that occurs in the charging stand 40 will be described. FIG. 11 shows a charging trouble detection notification routine. This charging trouble detection notification routine is performed in cooperation with the charging ECU 170, the power feeding ECU 60, and the vehicle-mounted navigation device 300. The left side of the drawing represents processing executed by the power feeding abnormality detection unit 72 of the power feeding ECU 60, the center of the drawing represents processing executed by the charging abnormality detection unit 182 of the charging ECU 170, and the right side of the drawing represents transmission of charging trouble information of the in-vehicle navigation device 300. This represents processing executed by the unit 314. The charging trouble detection notification routine is repeated at a predetermined short cycle.

  The processing on the charging ECU 170 side in the center of the drawing will be described. When this routine is activated, the charging ECU 170 first determines whether or not the plug 52 of the charging cable 51 is connected to the power receiving connector 110 based on the contact state of the plug detection switch 113 in step S41. When the plug 52 is not connected to the power receiving connector 110 (S41: No), this routine is once ended. Since this routine is repeated at a predetermined cycle, the routine waits until the plug 52 is connected to the power receiving connector 110.

  When the plug 52 is connected to the power receiving connector 110 (S41: Yes), next, in step S42, it is determined whether or not a power feeding signal is received. The power supply signal is transmitted from the power supply ECU 170 by PCL communication while power is supplied from the charger 50. When the power supply signal is not transmitted (S42: No), this routine is temporarily ended. Therefore, in step S42, the process waits until a power supply signal is transmitted.

  When the charging ECU 170 repeats such processing and receives a power supply signal (S42: Yes), in the subsequent step S43, the charging ECU 170 reads the plug voltage Vp detected by the plug voltage sensor 114, and the plug voltage Vp is set in a normal voltage range set in advance. It is determined whether it is within. The normal voltage range is set to a range that takes into account the allowable error α around the reference voltage Vo. Therefore, in this step S43, it is determined whether or not the plug voltage Vp is in the range of (Vp−α) to (Vp + α).

  When the plug voltage Vp is not within the normal voltage range (S43: No), the proper power supply from the charger 50 is not performed. In that case, the charging ECU 170 transmits a stand-side abnormality detection signal as a charging abnormality detection signal to the power feeding ECU 60 and the vehicle-mounted navigation device 300 in step S44, and this routine is temporarily terminated.

  On the other hand, when the plug voltage Vp is in the normal voltage range (S43: Yes), the proper power supply from the charger 50 is performed. In this case, the charging ECU 170 checks whether there is an abnormality in the charging system on the electric vehicle 100 side by the processing from step S45. First, in step S45, the SOC detected by the SOC detection unit 121 is read to determine whether or not the SOC has increased. If the charging system in electric vehicle 100 is normal, the SOC should gradually increase due to the supply of power from charger 50.

  If the increase in SOC is not detected in step S45, charging ECU 170 determines in step S46 whether or not a predetermined time has elapsed after receiving the power supply signal. If the predetermined time has not elapsed, this routine is temporarily terminated. This routine is repeated at a predetermined cycle. Therefore, while power is being supplied from the charger 50, the determination as to whether or not the SOC is increasing is repeated. If an increase in SOC is not detected even after a predetermined time has elapsed (S46: Yes), it can be estimated that the battery 120 is not normally charged. In that case, charging ECU 170 determines that an abnormality has occurred in the charging system on electric vehicle 100 side, and in step S47, as the charging abnormality detection signal, vehicle-side abnormality detection signal is supplied to power supply ECU 60 and in-vehicle navigation device 300. Transmit, and this routine is terminated once. On the other hand, when an increase in SOC is detected (S45: Yes), it is estimated that the battery 120 is properly charged, and the charging abnormality detection signal is not transmitted.

  In the present embodiment, the abnormality of the charging system on the electric vehicle 100 side is determined based on whether or not the SOC increases. For example, the charging current flowing in the battery 120 is measured, and the charging current does not flow. In this case, it may be determined that the charging system on the electric vehicle 100 side is abnormal (a vehicle-side abnormality detection signal is transmitted).

  Next, processing performed by the power feeding ECU 60 will be described. When this routine is started, the power supply ECU 60 determines in step S51 whether or not an ON command signal for closing the power supply switch 78 is output. The power supply switch 78 is maintained in the ON state (contact closed) by the switch drive circuit while the ON command signal is output from the power supply control unit 71 to the switch drive circuit (not shown). Therefore, in step S51, the control signal of the switch drive circuit output from the power supply control unit 71 is read and determined.

  The power feeding ECU 60 once ends this routine when the ON command signal is not output. This routine is repeated at a predetermined cycle. Therefore, it waits until the ON command signal of the power supply switch 78 is output. Then, when the ON command signal of the power supply switch 78 is output, a power supply signal indicating that power is being supplied from the charger 50 is transmitted to the charging ECU 170 via the PLC communication control unit 73 in step S52. This power supply signal is a signal that is confirmed by the charging ECU 170 in step S42. Therefore, by transmitting this power supply signal, the charging ECU 170 starts the abnormality detection process from step S43.

  Subsequently, in step S53, the power supply ECU 60 determines whether or not a stand side abnormality detection signal has been received. The stand side abnormality detection signal is a signal transmitted in step S44 when the charging ECU 170 detects a power feeding abnormality of the charger 50. When the power supply ECU 60 receives the stand side abnormality detection signal (S53: Yes), in step S54, the power supply ECU 60 displays a message indicating that an abnormality has occurred in the charger 50 of the charging stand 40. 54. Subsequently, in step S55, charging station information is transmitted as charging trouble information to the charging infrastructure information providing apparatus 200 via the external communication control unit 74.

  On the other hand, if the stand side abnormality detection signal has not been received in step S53, it is determined in step S56 whether or not the vehicle side abnormality detection signal has been received. This vehicle-side abnormality detection signal is a signal transmitted in step S47 when charging ECU 170 detects an abnormality in the charging system of electric vehicle 100. When power supply ECU 60 receives the vehicle-side abnormality detection signal (S56: Yes), in step S57, power supply ECU 60 displays a message indicating that charging abnormality has occurred in electrically powered vehicle 100 on display unit 54 of charger 50. To do. If the vehicle-side abnormality detection signal has not been received in step S56, this routine is once terminated, and the above-described processing is repeated at a predetermined cycle.

  Next, a process performed by the in-vehicle navigation device 300 (charging trouble information transmission unit 314) will be described. When this routine is started, the vehicle-mounted navigation device 300 determines whether or not a vehicle-side abnormality detection signal has been received in step S61. This vehicle-side abnormality detection signal is a signal transmitted in step S47 when charging ECU 170 detects an abnormality in the charging system of electric vehicle 100. When the vehicle-mounted navigation device 300 receives the vehicle-side abnormality detection signal (S61: Yes), the vehicle-mounted navigation device 300 displays a message indicating that a charging abnormality has occurred in the electric vehicle 100 on the display unit 350 in step S62. Subsequently, in step S63, vehicle information is transmitted as charging trouble information to the charging infrastructure information providing apparatus 200 via the wireless communication control unit 370.

  On the other hand, if the vehicle side abnormality detection signal is not received in step S61, it is determined in step S64 whether or not the stand side abnormality detection signal has been received. The stand side abnormality detection signal is a signal transmitted in step S44 when the charging ECU 170 detects a power feeding abnormality of the charger 50. When the vehicle-mounted navigation device 300 receives the stand-side abnormality detection signal (S64: Yes), in step S65, the in-vehicle navigation device 300 displays a message indicating that an abnormality has occurred in the charger 50 of the charging stand 40 on the display unit 350. indicate. If the stand side abnormality detection signal has not been received in step S64, this routine is once terminated, and the above-described processing is repeated at a predetermined cycle.

  According to this charging trouble detection notification routine, the charging ECU 170 determines whether the cause of the charging trouble in which the charging of the battery 120 of the electric vehicle 100 is malfunctioning is the charger 50 side or the electric vehicle 100 side. To detect. When a charging trouble is detected, a message indicating that the charging trouble has occurred is also displayed on the display unit 350 of the in-vehicle navigation device 300 and the display unit 54 of the charger 50 together with the cause of the charging trouble. Thereby, the occupant can grasp the charging trouble by distinguishing whether the cause is the charger 50 side or the electric vehicle 100 side. Moreover, since the notification of the occurrence of the charging trouble is performed at two places, that is, the charger 50 and the in-vehicle navigation 300, it is difficult to overlook and the passenger can be notified quickly. In addition, it is preferable to notify the occurrence of charging trouble in parallel with voice guidance in addition to the screen display.

  Next, processing when charging trouble information is received in charging infrastructure information providing apparatus 200 will be described. FIG. 12 shows a charging trouble processing routine executed by the vehicle side trouble processing unit 217 and the stand side trouble processing unit 218 of the charging infrastructure information providing apparatus 200. The charging trouble processing routine is repeatedly executed at a predetermined cycle.

  When this routine is activated, charging infrastructure information providing apparatus 200 first determines whether or not charging trouble information has been received in step S71. The charging trouble information is information transmitted from the in-vehicle navigation device 300 or the charger 50 when the battery 120 of the electric vehicle 100 cannot be charged properly. If charging trouble information has not been transmitted, this routine is temporarily terminated.

  When this routine is repeated at a predetermined cycle and charging trouble information is received, it is determined in step S72 whether or not the charging trouble information is charging station information. If the charging trouble information is charging station information (S72: Yes), the charging station information is transmitted to the charging station supplier 30 in step S73. Thereby, the charging stand supply company 30 can grasp | ascertain the charging stand 40 in which the trouble has generate | occur | produced, and its charger 50. FIG. Therefore, a double management system can be formed by the management by the charging station supplier 30 and the management by the charging infrastructure information center 20.

  In this case, the charging station supply company 30 can quickly take measures against the charging trouble. For example, the charging station supplier 30 uses a guidance indicator or a voice guidance device (not shown) provided on the charging stand 40 to inform all the people at the charging stand 40 that the charger 50 is malfunctioning. Can be notified. As a result, it is possible to notify the occupants of other vehicles of the occurrence of trouble. Moreover, repair arrangement of the charger 50 can be performed at an early stage.

  Subsequently, charging infrastructure information providing apparatus 200 extracts alternative charging station 40 in step S74. This process is the same as the process of step S15 when a power failure occurs, and a plurality of alternative charging stations 40 arranged in the vicinity of the charging stained 40 where the trouble has occurred are extracted. Then, a list of alternative charging stations 40 is created in the order in which charging can be started substantially earlier with reference to the usage status information of the alternative charging stations 40. Subsequently, in step S75, the list of alternative charging stations 40 is transmitted to the in-vehicle navigation device 300 as charging infrastructure information, and this routine is temporarily ended.

  Thereby, in the vehicle-mounted navigation device 300, the list of alternative charging stations 40 is displayed on the display unit 350 by the charging infrastructure information notification routine of FIG. 9 described above. In this case, the message displayed in step S65 (a message indicating that an abnormality has occurred in the charging station 40) may be left and displayed as it is. Thereby, the passenger | crew can grasp | ascertain the suitable alternative charging stand 40. FIG.

  On the other hand, if the charging trouble information received in step S71 is not charging station information (S72: No), that is, if the received trouble information is vehicle information, the charging infrastructure information providing apparatus 200 in step S76, the electric vehicle 100 The vehicle dealer 85 closest to is extracted, and vehicle information is transmitted to the vehicle dealer 85. Thereby, the vehicle dealer 85 can grasp the electric vehicle 100 in which the charging trouble has occurred. In this case, the vehicle dealer 85 performs wireless communication with the electric vehicle 100 and reads the error history information from the error history storage memory provided in the electric vehicle 100, so that the charging of the battery 120 is malfunctioning. Can be grasped.

  Subsequently, charging infrastructure information providing apparatus 200 transmits vehicle dealer information for guiding to extracted vehicle dealer 85 to in-vehicle navigation apparatus 300 in step S77. When receiving the vehicle dealer information, the vehicle-mounted navigation device 300 displays a message for guiding the vehicle dealer 85 and information related to the vehicle dealer 85 on the display unit 350. In this case, the message displayed in step S62 (a message indicating that a charging abnormality has occurred in the electric vehicle 100) may be left as it is.

  When the charging infrastructure information providing apparatus 200 executes the process of step S75 or step S77, the charging infrastructure information providing apparatus 200 once ends this routine and then repeats the same process at a predetermined cycle.

  According to this charging trouble processing routine, an appropriate coping method to be taken next can be proposed to the passenger of the electric vehicle 100 when a charging trouble occurs. Further, when a charging trouble occurs due to the cause on the electric vehicle 100 side, the vehicle dealer 85 knows the cause of the failure before the occupant contacts the vehicle dealer 85. Processing (part procurement, securing of personnel, etc.) can be performed quickly. Thereby, the service of the vehicle dealer 85 is improved.

  In addition, when a charging trouble occurs due to the charging station 40 side, the information is notified to the charging station supply company 30, so the charging station supply company 30 takes an early action for the charging trouble. be able to. Moreover, in the charging infrastructure information provision apparatus 200, since the charging station 40 in which the charging trouble has occurred can be handled as the charging station 40 in the area where the power failure has occurred, the power failure information can be enhanced.

  Thus, according to this embodiment, since the system in the event of a failure in the charging facility infrastructure is in place, the occupant can go out on the electric vehicle 100 with peace of mind. Thereby, the electric vehicle 100 friendly to the global environment can be spread.

  In addition, the charging infrastructure information provision apparatus 200 in this embodiment corresponds to the charging facility information provision apparatus of this invention. In addition, the infrastructure failure information acquisition unit 211 in the charging infrastructure information providing apparatus 200 corresponds to the failure information acquisition unit of the present invention, the alternative stand extraction unit 214 corresponds to the charging facility extraction unit, and the alternative station information transmission unit 215 corresponds to the present invention. It corresponds to the information providing means. Further, the vehicle information acquisition unit 212 in the charging infrastructure information providing apparatus 200 corresponds to the vehicle information acquisition unit of the present invention, the vehicle extraction unit 213 corresponds to the vehicle extraction unit of the present invention, and the charging trouble information acquisition unit 216 of the present invention. The vehicle-side trouble processing unit 217 and the stand-side trouble processing unit 218 correspond to the charging trouble notification unit of the present invention. In addition, the vehicle-side trouble processing unit 217 in the charging infrastructure information providing apparatus 200 corresponds to the charging trouble vehicle information providing unit of the present invention, and the stand-side trouble processing unit 218 corresponds to the charging trouble facility information providing unit of the present invention. The process of step S74 performed by the side trouble processing unit 218 corresponds to the alternative charging facility extraction unit of the present invention, and the process of step S75 performed by the stand side trouble processing unit 218 corresponds to the alternative charging facility information providing unit of the present invention.

  Although the charging facility information providing apparatus according to the present embodiment has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the object of the present invention.

  For example, in the present embodiment, a system configuration in which charging infrastructure information is transmitted from the charging infrastructure information providing apparatus 200 to the in-vehicle navigation apparatus 300 is adopted, but a mobile terminal 500 (such as a mobile phone) of a vehicle occupant registered in advance. The system configuration may also be such that the charging infrastructure information is transmitted. In this case, when the mobile terminal 500 is equipped with a navigation function, it is preferable to perform route guidance to the charging station 40 using the navigation screen, as with the in-vehicle navigation device 300.

  Moreover, in this embodiment, although the charging infrastructure information provision apparatus 200 employs a system configuration in which the target vehicle is extracted based on the infrastructure failure information, all the electric vehicles 100 are extracted without extracting the target vehicle. The system configuration may be such that charging infrastructure information representing a list of alternative charging stations 40 in the vicinity of the power outage failure occurrence area is transmitted. In this case, if the charging station information is stored in advance in the storage unit on the electric vehicle 100 side, the charging infrastructure information providing apparatus 200 only transmits the infrastructure failure information to the electric vehicle 100 side. Based on the position information of the electric vehicle 100 and the infrastructure failure information with the in-vehicle navigation device 300 or the mobile terminal 500 equipped with the GPS, the approach relationship between the electric vehicle 100 and the power failure failure area is determined, and the electric When the vehicle 100 exists in a power failure failure area, the alternative charging station 40 can be extracted and the information can be provided to the occupant via the display unit 350. In such a system configuration, the in-vehicle navigation device 300 corresponds to the charging facility information providing device of the present invention.

  In addition, when the destination is set when extracting the alternative charging stand 40, it is arranged between the current position of the electric vehicle 100 and the destination in consideration of the position information of the destination. The charging station 40 in which no power failure has occurred may be extracted from the charging station 40.

  In the present embodiment, when a charging trouble occurs, if the cause is the electric vehicle 100 side, charging trouble information is transmitted from the in-vehicle navigation device 300 to the charging infrastructure information providing device 200. A configuration in which charging trouble information is directly transmitted to the vehicle dealer 85 from the electric vehicle 100 side (the in-vehicle navigation device 300 or the portable terminal 500 equipped with the GPS) may be employed. In this case, vehicle dealer information is stored in advance in the storage unit on the electric vehicle 100 side, and the vehicle dealer 85 near the vehicle position is extracted on the electric vehicle 100 side using the vehicle dealer information and the vehicle position information. Then, the charging trouble information may be transmitted to the extracted vehicle dealer 85.

  Even when the cause of the charging trouble is the charger 50 side, the charging trouble information is transferred from the electric vehicle 100 side (the in-vehicle navigation device 300 or the portable terminal 500 equipped with GPS) to the charging stand supplier company 30. It is also possible to adopt a configuration for directly transmitting. In this case, the charging station 40 can identify the charging station 40 by transmitting the vehicle position information as charging trouble information to the charging station supplier 30.

  Therefore, when the in-vehicle navigation device 300 is provided with an extraction function of the alternative charging station 40, a notification function to the vehicle dealer, or a notification function to the charging station supplier company 30, the in-vehicle navigation device 300 is charged with the charging facility information of the present invention. This corresponds to a providing device.

  In addition, as a system that does not extract the target vehicle, for example, a configuration in which charging infrastructure information is transmitted only from the radio communication base station 90 close to the power failure failure area may be used. Also in this system configuration, the charging infrastructure information is provided to the electric vehicle 100 existing in and near the power failure failure area.

  In this embodiment, a power failure failure in the charging facility infrastructure is detected by the smart grid network. However, when a power failure failure occurs throughout the smart grid network, for example, the power failure failure is caused by other infrastructure such as the Internet network. A system configuration for acquiring information may also be used. In this case, even when the electric vehicle 100 cannot travel to the charging station 40 due to a wide-range power failure, it is possible to notify the occupant early, so that it is possible to support the occupant's decision making.

  Further, in the present embodiment, the charging station 40 in which no power failure has occurred is extracted and charging infrastructure information representing the extracted charging station 40 is provided. The structure which extracts and provides the charging infrastructure information showing the extracted charging stand 40 may be sufficient. Even in that case, the occupant can grasp the available charging station 40.

  In the present embodiment, the charging infrastructure information is displayed on the display unit 350 of the in-vehicle navigation device 300 to notify the occupant. However, the occupant may be notified by voice announcement. As the interface device for notifying the occupant of charging infrastructure information, in addition to the in-vehicle navigation device 300, an in-vehicle display device, an in-vehicle audio device, a portable terminal (portable information terminal such as a cellular phone) possessed by the occupant, and the like can be used.
