  The charging port 101 connects the cable 202 and the vehicle 100 when charging the battery 102 from the charging device 201. The vehicle side detects that the cable 202 is connected to the charging port 101 by receiving a signal sent from the charging device 200 via a signal line incorporated in the cable 202.

  The battery 102 supplies necessary power to the motor 106 and the auxiliary machinery 107. The battery 102 mounted on the vehicle 100 is called a secondary battery. By connecting the battery 102 and the charging device 201 with the cable 202, the battery 102 can be charged multiple times with electric power from the outside of the vehicle.

  The sensor 103 is a device that detects electricity charged or discharged from the battery 102. In order to grasp the state of the battery 102, the sensor 103 is electrically connected to the input / output terminal of the battery 102. For example, a current sensor is used as the sensor 103.

  The DC-DC converter 104 generates a voltage obtained by stepping up or down the voltage of the battery 102 and supplies a voltage required for the inverter 105 and the auxiliary devices 107.

  The inverter 105 is a device that converts electric power sent from the DC-DC converter 104 from direct current to alternating current. The output control of the motor 106 is performed by controlling the AC power output from the inverter 105.

  The motor 106 is a device that converts electric power supplied from the battery 102 into motive power. As the motor 106, for example, a three-phase AC synchronous motor is used.

  Auxiliary devices 107 indicate peripheral devices provided in the vehicle 100 excluding the motor 106. For example, electronic devices such as an audio device that plays music, a power window that automatically opens and closes a window, and a car navigation system that provides map information are examples.

  As described above, the electricity stored in the battery 101 is used for a plurality of purposes such as the motor 106 and the auxiliary machinery 107. When the remaining amount of the battery 102 is reduced, the driver stops the vehicle 100 at the parking position of the charging facility 200 located around the vehicle 100 and charges the battery 102.

  FIG. 2 is a block diagram showing a state detection device 400 for a charging facility according to the present embodiment. The charging facility state detection apparatus 400 includes a vehicle 100 and a center 300. The components of the charging facility state detection device 400 will be described below.

  The vehicle 100 includes a controller 111, a transceiver 112, a position detector 113, a display 114, a map information database 115, a charging information database 116, a travel history database 117, and a charging port 101.

  The controller 111 is a device that connects the transceiver 112, the position detector 113, the display 114, the map information database 115, the charging information database 116, the travel history database 117, and the charging port 101, and controls them. It is. The controller 111 may be a microcontroller that controls a plurality of semiconductor ICs, for example.

  The transceiver 112 transmits the battery information, the travel history of the vehicle 100, and the position information of the charging facility 200 sent from the controller 111 to the center 300 side. The transceiver 112 also receives information sent from the center 300 side.

  The position detector 113 includes a GPS (Global Positioning System) receiver. The GPS receiver can receive signals from several satellites in the sky among a plurality of GPS satellites and know the current position of the vehicle 100. The current position received by the GPS receiver corresponds to the current position displayed by the car navigation system. The position information of the current location detected by the position detector 113 is sent to the controller 111 and stored in the travel history database 117.

  The display 114 is a device that displays map information. The display 114 is used when displaying map information stored in the map database 115 by the car navigation system.

  The map database 115 stores map information including road information and charging facility information. The charging facility information includes location information of the charging facility 200, presence / absence of a charging device corresponding to quick charging, failure history of the charging device 201, and the like. The charging facility information can be displayed on the display 114 together with road information. The map information stored in the map database 115 is updated to the latest information by registering the map information received by the transceiver 112 in the map information database 115.

  Charging information database 116 stores battery information of vehicle 100. The battery information of the vehicle 100 includes, for example, the amount of charge of the battery 102, the value of the remaining battery level at the start of charging, and the value of the remaining battery level at the end of charging. When a current sensor is used as the sensor 103, the charge amount of the battery 102 can be calculated by integrating the current values detected by the current sensor.

  The travel history database 117 stores a travel history of the vehicle 100 that has traveled around the parking position of the predetermined charging facility 200. The travel history of the vehicle 100 includes, for example, the position information of the vehicle 100, the time when the position detector 113 detects the position information of the vehicle 100, and the travel distance. The position information of the vehicle 100 and the time when the position detector 113 detects the position information of the vehicle 100 are sent from the position detector 113 to the travel history database 117 via the controller 111.

  Next, the configuration of the center 300 will be described. The center 300 includes a controller 301, a transceiver 302, a map information database 303, a charging information database 304, and a travel history database 305. The center 300 is a device that manages map information, charging information, and travel history information of a plurality of vehicles 100, and is, for example, a server.

  The controller 301 is a device that connects the transceiver 302, the map information database 303, the charging information database 304, and the travel history database 305 and controls them. Similar to the controller 111 mounted on the vehicle 100, a microcontroller that controls a plurality of semiconductor ICs may be used.

  The controller 301 sets an abnormal state in advance, and determines whether the battery information of the vehicle 100 and the travel history of the vehicle sent from the transceiver 112 match the set abnormal state. The abnormal state here is a state indicating that the battery 102 is not normally charged in the predetermined charging facility 200, for example. When it is determined that the state is abnormal, the controller 301 estimates the number of applicable vehicles.

  Furthermore, the controller 301 detects the predetermined charging facility 200 as a charging facility 200 that cannot normally charge the battery 102 when the estimated number of vehicles is equal to or greater than a predetermined value. The charging facility 200 that cannot normally charge the battery 102 is charged so that the battery 102 cannot be charged normally due to a failure of the charging device 201, a limitation of power supply to the charging facility 200 due to a power failure, out of service hours, or the like. Facility 200.

  The transceiver 302 receives the battery information of the vehicle 100, the travel history of the vehicle 100, and the position information of the charging facility 200 sent from the transceiver 112. The transceiver 302 transmits information sent from the controller 301 to the plurality of vehicles 100.

  The map information database 303 stores map information. The map information includes location information of the charging facility 200 in addition to road information. The map information stored in the map information database 303 becomes the latest information by updating the map information. The updated map information is transmitted to the plurality of vehicles 100 by the receiver 302 via the controller 301.

  The charging information database 304 stores battery information of the plurality of vehicles 100 received by the transceiver 302. The battery information stored in the charging information database 304 is sent to the controller 301 and used when detecting the charging facility 200 that cannot normally charge the battery 102.

  The travel history database 305 stores travel histories of a plurality of vehicles 100 received by the transceiver 302. The battery information of the vehicle 100 stored in the travel history database 305 is sent to the controller 301 and used when detecting the charging facility 200 that cannot normally charge the battery 102.

  Control processing performed by the vehicle 100 in the charging facility state detection apparatus 400 will be described with reference to the flowchart of FIG.

  In step S <b> 10, the controller 111 acquires position information of the predetermined charging facility 200. The location information of the charging facility 200 may be acquired from the map information database 115. Then, the process proceeds to step S20.

  In step S <b> 20, the controller 111 acquires battery information of the vehicle 100 from the sensor 103. The battery information acquired by the sensor 103 is stored in the charging information database 116. The battery information detected in real time by the sensor 103 includes time information such as the time detected by the sensor 103 in addition to the charge rate and the charge amount. The battery information includes the time when the cable 202 of the charging device 201 is connected to the charging port 101, the value of the remaining amount of the battery 102 at that time, the time when a certain time has elapsed from the time when the charging device 101 is connected, and the time Value of the remaining battery 102 is included. Then, the process proceeds to step S30.

  In step S <b> 30, the controller 111 determines whether or not the battery 102 has been charged at the predetermined charging facility 200. Whether or not the battery 102 has been charged at the predetermined charging facility 200 is confirmed by confirming that the cable 202 of the charging apparatus 201 and the charging port 101 are connected, and confirming the connection, This can be determined by the increase in value. The connection between the cable 202 and the charging port 101 can be confirmed by the controller 111 acquiring a detection signal sent when the connection is made. If the battery 102 has been charged, the process proceeds to step S60. On the other hand, if the battery 102 is not charged, the process proceeds to step S40.

  In step S <b> 40, the controller 111 selects a travel history to be transmitted by the transmitter 112 using the value of the remaining amount of the battery 102. Specifically, it is determined whether the value of the remaining amount of the battery 102 is equal to or less than a certain value. If the value of the remaining amount of the battery 102 is equal to or less than a certain value, the battery 102 needs to be charged, and the process proceeds to step S50. On the other hand, if the value of the remaining amount of the battery 102 is not less than the predetermined value, the flow is terminated because the battery 102 is not in a state of charging.

  In step S50, the controller 111 acquires the position information of the vehicle 100 from the position detector 113 in a state where the battery 102 needs to be charged. The position information of the vehicle 100 acquired by the position information detector 113 is stored in the travel history database 117. The controller 111 can grasp the travel history of the vehicle by analyzing the time-series position information. The travel history stored in the travel history database 117 includes, for example, the position information of the vehicle 100, the time when the position detector 113 detects the position information of the vehicle 100, and the travel distance. Then, the process proceeds to step S60.

  In step S60, the transceiver 112 transmits the battery information and travel history acquired in steps S20 and S50 to the center 300 side. In step S <b> 30, when the charging facility 200 charges the battery 102, the transceiver 112 transmits battery information including the charging rate and time information of the battery 102 to the center 300 side. On the other hand, in step S40, when the remaining amount value of the battery 102 is equal to or less than a certain value, the transceiver 112 transmits a traveling history including the position information of the vehicle 100 and its time information to the center 300 side. Then, the flow ends.

  Note that the determinations made in steps S30 and S40 can also be made on the center 300 side. In this case, since the information to be transmitted to the center 300 is not selected according to the determinations in step S30 and step S40, the amount of information transmitted to the center 300 increases.

  Control processing performed in the center 300 in the charging facility state detection apparatus 400 will be described with reference to the flowchart of FIG.

  In step S <b> 100, the transceiver 302 receives the location information of the charging facility 200, the travel history of the vehicle 100, and the battery information of the vehicle 100 sent from the transceiver 112. Information received by the transceiver 302 is sent to the controller 301. Then, the process proceeds to Step 110.

  In step S110, the controller 301 estimates the number of vehicles having an abnormal state. The abnormal state is set using battery information of the vehicle 100 or a running pattern. The controller 301 compares the information sent from the vehicle 100 side with the set abnormal state, and estimates the number of vehicles corresponding to the set abnormal state. Detailed description will be given later with reference to FIGS. 5, 6, and 7. Then, the process proceeds to step 120.

  In step S120, the controller 301 determines whether or not the number of vehicles estimated by the flow in step S110 is equal to or greater than a predetermined number. If the estimated number of vehicles is greater than or equal to the predetermined number, it indicates that there is a high possibility that the battery 102 is a charging facility 200 that cannot normally charge the battery 102. The predetermined number used when determining the estimated number of vehicles can be set from the outside. By increasing the predetermined number, normal charging of the predetermined charging facility 200 to the battery 102 cannot be performed by mistake. It is possible to prevent the charging facility 200 from being determined. If the estimated number of vehicles is greater than or equal to the predetermined number, the process proceeds to step S140. On the other hand, if the estimated number of vehicles is less than or equal to the predetermined number, the process proceeds to step S130.

  In step S130, the map information database 303 registers the number of vehicles estimated in step 110 as charging facility information. The purpose of registering the number of vehicles estimated in step S110 in the map information database 303 is to allow the number of vehicles estimated in the past at a predetermined charging facility 200 to be referred to. Then, the flow ends.

  In step S140, the controller 301 determines that the predetermined charging facility 200 is a charging facility 200 that cannot normally charge the battery 102 based on the determination result of step S120. Then, the process proceeds to step S150.

  In step S150, the map information database 303 registers the number of vehicles estimated in step S110, the determination result in step S140, and the time zone outside the usage time of the predetermined charging facility 200 as charging facility information. A method of specifying a time zone outside the usage time of the predetermined charging facility 200 will be described after explaining the flow of FIG. Then, the process proceeds to step S160.

  In step S160, the map information database 303 updates the stored map information to the map information including the charging facility information registered in step S150. Here, the determination result determined as the charging facility 200 that cannot normally charge the battery 102 in step S140 can be reflected in the map information. Then, the process proceeds to step S170.

  In step S170, the transceiver 302 transmits the map information updated in step S160 to the plurality of vehicles 100. The vehicle 100 receives the map information from the center 300 by the transceiver 112 by transmitting the position information of the vehicle 100 detected by the position detector 113 to the center 300. The latest map information received by the transceiver 112 includes position information of the charging facility 200 where the battery 102 cannot be charged normally. As a result, the driver can know whether or not the charging facility 200 located around the vehicle 100 is a charging facility 200 that cannot normally charge the battery 102. Further, the charging facility state detection device 400 can also prevent the display 114 from displaying position information of the charging facility 200 where the battery 102 cannot be charged normally. Thereby, the car navigation system can exclude the charging facility 200 that cannot normally charge the battery 102 from the search target of the charging facility 200. Then the flow ends.

  In step S <b> 170, the transceiver 302 transmits a time zone outside the usage time of the predetermined charging facility 200 to the vehicle 100. In this case, first, the controller 301 specifies, for each of a plurality of vehicles, a time zone including a time corresponding to the position of the vehicle 100 in the travel history indicating that the battery is not normally charged at the predetermined charging facility 200. To do. Next, when the number of vehicles is equal to or greater than a predetermined number in the specified time zone, the controller 301 detects the predetermined charging facility 200 as a charging facility outside the usage time. Finally, when the predetermined charging facility 200 is detected as a charging facility outside the usage time in the specified time zone, the specified time zone and the detection result are transmitted to the vehicle 100 by the transceiver 302. Accordingly, the charging facility state detection apparatus 400 can notify the driver of a time zone outside the usage time of the predetermined charging facility 200. Then, the flow ends.

  Control processing for estimating the number of vehicles having an abnormal traveling history in the charging facility state detection apparatus 400 will be described with reference to the flowchart of FIG. The flow shown here corresponds to step S110 in FIG.

  In step S111, the controller 301 sets a predetermined charging application 200 and its surrounding area. For example, the controller 301 selects a predetermined charging facility 200 from a plurality of charging facilities 200, and sets an area such as a radius of 1 km from the selected predetermined charging facility 200. The number of vehicles in step S115 is estimated using the travel history and battery information of the vehicle 100 existing in the set area. In an area where the charging facilities 200 are dense, the area is set small, and in an area where the charging facilities 200 are not dense, the area is set large. Thereby, the number of vehicles existing around the predetermined charging facility 200 can be made constant. Then, the process proceeds to step S112.

  In step S112, the controller 301 determines whether or not the traveling history of the vehicle 100 received by the transceiver 302 is a traveling pattern indicating that the battery is not normally charged at a predetermined charging facility. A traveling pattern indicating that the battery is not normally charged at a predetermined charging facility is set in advance as a traveling pattern in which the traveling vehicle 100 decelerates to stop at the charging facility 200 but does not stop at the charging facility 200. . When the travel history of the vehicle 100 corresponds to the preset travel pattern, the process proceeds to step S115. On the other hand, when the travel history of the vehicle 100 does not correspond to the preset travel pattern, the process proceeds to step S113.

  In the traveling pattern set in advance in step S112, for example, the charging rate of the battery 102 decreases, and the vehicle 100 decelerates to stop at the charging facility 200 in order to charge the battery 102, but does not stop at the charging facility 200. The traveling pattern of traveling as it is is shown. One of the reasons why the vehicle does not stop at the charging facility 200 is that the charging device 201 fails and the battery 102 cannot be charged.

  As a condition for acquiring the travel history of the vehicle 100, it is determined in step S40 that the value of the remaining amount of the battery 102 is equal to or less than a certain value. Therefore, step S112, step S113, and step S114 are limited to the vehicle 100 that needs to charge the battery 102, and the determination is performed.

  In step S113, the controller 301 determines whether or not the traveling history of the vehicle 100 received by the transceiver 302 is a traveling pattern indicating that the battery is not normally charged at a predetermined charging facility. The traveling pattern indicating that the battery is not normally charged at the predetermined charging facility is less than the time when the vehicle 100 stops around the parking position of the charging facility 200 during normal charging, and the charging facility A travel pattern that does not stop at the parking position 200 is set in advance. When the travel history of the vehicle 100 corresponds to the preset travel pattern, the process proceeds to step S115. On the other hand, if the travel history of the vehicle 100 does not correspond to the preset travel pattern, the process proceeds to step S114.

  In the traveling pattern set in advance in step S113, for example, the vehicle 100 cannot stop at the parking position of the charging facility 200, and the vehicle 100 stops around the charging facility 200 and stops at the parking position of the charging facility 200. The driving pattern is shown as it is. In addition, the determination condition of step S113 is set such that when shopping around a predetermined charging facility 200, a condition that the vehicle 100 is less than the stop time during normal charging is provided in order to exclude a situation where the vehicle 100 stops for a long time. ing.

  In step S <b> 114, the controller 301 determines whether or not the travel history of the vehicle 100 received by the transceiver 302 is a travel pattern indicating that the battery is not normally charged at the predetermined charging facility 200. The traveling pattern indicating that the battery is not normally charged at the predetermined charging facility 200 is set in advance as a traveling pattern in which the time when the vehicle stops at the charging facility 200 is less than the time when the vehicle stops during normal charging. When the travel history of the vehicle 100 corresponds to the preset travel pattern, the process proceeds to step S115. On the other hand, if the travel history of the vehicle 100 does not correspond to the preset travel pattern, the flow ends.

  The situation set in advance in step S <b> 114 is, for example, that the normal charging time for the battery 102 is about 30 minutes, but the charging device 201 has a problem, so the vehicle 100 is at the parking position of the charging facility 200 for 5 minutes. It shows the situation where the car stops only to a certain extent.

  It should be noted that there is no problem even if the order of steps S112, S113, and S114 is reversed.

  In step S115, the controller 301 estimates the number of vehicles corresponding to the travel history of the vehicle 100 in a preset situation based on the determination results in steps S112, S113, and S114. Then, the flow ends.

  According to the present invention, the position information indicating the position of the charging facility 200 is acquired, and the travel history information of the vehicle 100 and the battery information indicating the charging state of the battery 102 mounted on the vehicle 100 are obtained from the plurality of vehicles 100. Acquired, based on the travel history information of the vehicle 100, the position information of the charging facility 200, and the battery information of the vehicle 100, out of a plurality of vehicles existing around the parking position of the predetermined charging facility or the parking position The number of vehicles indicating the travel history is estimated, and when the estimated number of vehicles is equal to or greater than a predetermined number, the predetermined charging facility 200 is detected as a charging facility 200 that cannot normally charge the battery 102. As a result, the charging facility state detection apparatus 400 can detect the predetermined charging facility 200 as a charging facility 200 that cannot normally charge the battery 102.

  Further, in the present invention, when the predetermined charging facility 200 does not have a communication facility, or in a situation where communication with the center 300 is not possible due to an abnormality in the predetermined charging facility 200, the charging facility state detection device 400 The charging facility 200 can be detected as the charging facility 200 that cannot normally charge the battery 102.

  According to the present invention, in a situation where the battery needs to be charged, the travel history of traveling around the parking position is specified for each of the plurality of vehicles, and the specified travel history and the abnormal travel pattern are compared for each of the plurality of vehicles. By doing so, the number of vehicles is estimated. Thereby, the number of vehicles showing an abnormal traveling history can be estimated.

  According to the present invention, the case where the charging rate of the battery 102 is equal to or less than a certain value is specified as a situation where the battery 102 needs to be charged. Accordingly, the charging facility state detection device 400 uses the travel history of the vehicle 100 that is likely to use the predetermined charging facility 200, and the charging facility that cannot normally charge the predetermined charging facility 200 to the battery 102. 200 can be detected. Further, the charging facility state detection device 400 statistically analyzes the charging rate of the battery 102 when the battery 102 is charged, thereby limiting the number of vehicles that need to be charged to the battery 102. The accuracy of estimating can be improved.

  According to the present invention, the abnormal traveling pattern is a traveling pattern when the vehicle 100 decelerates to stop at the charging facility 200 but does not stop at the charging facility, and in the vicinity of the parking position of the predetermined charging facility 200. The stopping time of the vehicle 100 is less than the stopping time at the time of normal charging, and the traveling pattern when the vehicle 100 does not stop at the parking position of the predetermined charging facility 200 or the stopping time of the vehicle 100 at the predetermined charging facility 200 Is a traveling pattern when the vehicle is less than the stopping time during normal charging. As a result, the charging facility state detection device 400 uses a specific traveling history to estimate the number of vehicles corresponding to the traveling history indicating that the battery is not charged at the predetermined charging facility 200. The accuracy of detecting the charging facility as a charging facility that cannot normally charge the battery 102 can be improved.

  According to the present invention, when a predetermined charging facility 200 is detected as a charging facility that cannot normally charge the battery 102, the detected result is transmitted to the vehicle 100. As a result, the charging facility state detection device 400 can inform the driver of the location information of the charging facility 200 where the battery 102 cannot be charged normally. In addition, the charging facility state detection apparatus 400 can inform the driver of the location information of the charging facility 200 while avoiding the location information of the charging facility 200 where the battery 102 cannot be charged normally. In addition, for example, when the charging device 201 fails in the charging facility 200 where no manager is present at night or the charging facility 200 where the manager is not resident, the charging facility 200 in which the battery 102 cannot be normally charged by the driver. Location information can be notified.

  By the way, unlike the present invention, when the charging facility 200 that cannot perform normal charging is not detected, the following problems may be considered. For example, it is assumed that the charging facility where the vehicle arrives in a state where the charging rate of the battery is low is a charging facility that cannot perform normal charging. At this time, even if the vehicle is driven to charge at another charging facility, the charging rate of the battery is low, so the vehicle may not arrive at the other charging facility and may get stuck. .

  However, since the present invention informs the driver of the charging facility 200 that cannot perform normal charging, the driver can select a travel route that avoids the charging facility 200 that cannot perform normal charging. As a result, the present invention can avoid the situation of being stuck without being able to arrive at another charging facility, which has been cited as an example.

  According to the present invention, the travel history including the time corresponding to the position of the vehicle 100 is acquired, the abnormal travel history is selected, the time zone including the time of the selected travel history is specified for each of the plurality of vehicles, When the number of vehicles is equal to or greater than a predetermined number in the specified time zone, the predetermined charging facility 200 is detected as a charging facility outside the usage time, and the predetermined charging facility 200 is charged outside the usage time in the specified time zone. When detected as a facility, the specified time zone and detection result are transmitted to the vehicle 100. As a result, the charging facility state detection device 400 can notify the driver of a time period outside the service time of the predetermined charging facility 200.

  Note that step S30 and step S40 may be performed not on the vehicle side but on the center side. Further, the charging facility state detection device 400 need not be limited to the configuration including the vehicle 100 and the center 300, and may be implemented between a plurality of vehicles or within one vehicle.
