FIG. 2 is a block diagram showing a system configuration of the vehicle charge management system CS1 of the present embodiment.

As described above, the vehicle charging management system CS1 includes the in-vehicle navigation device 1 (abbreviated as in-vehicle navigation device in the drawing), the charging stand 200, and the central server 300.

The in-vehicle navigation device 1 corresponds to a vehicle terminal and an electric vehicle guidance and guidance device, and includes a CPU 2, a vehicle information storage unit 3, a GPS detection unit 4, a wireless communication unit 5, an operation unit 6, and an output unit 7.

The CPU 2 has a function of controlling the vehicle-mounted navigation device 1 as a whole by performing various calculations according to the operation of a predetermined program and exchanging information with other units and outputting various control instructions.

The vehicle information storage unit 3 is a storage medium that stores vehicle identification information that can uniquely identify the vehicle-mounted navigation device 1 or the individual electric vehicle V. Specific examples of the vehicle identification information include the manufacturer and serial number of the in-vehicle navigation device 1 or the electric vehicle V, the vehicle number of the electric vehicle V, the identification information on the communication line, the personal identification number such as the owner's telephone number, Alternatively, a combination thereof can be used.

Next, the charging station 200 corresponds to an equipment terminal, and includes a CPU 11, a vehicle authentication unit 12, a charging unit 13, a network communication unit 14, and a wireless communication unit 15.

Since the CPU 11 and the wireless communication unit 15 are functionally equivalent to those provided in the in-vehicle navigation device 1, description thereof is omitted here.

The vehicle authentication unit 12 authenticates the electric vehicle V in the charging station 100 with which communication with the wireless communication unit 15 has been established, and particularly during connection charging at that point in time via the charging unit 13 described later (or not) It has a function of authenticating the electric vehicle V that is in contact charging. This authentication process is performed by collating the vehicle identification information described above.

The charging unit 13 has a function of directly connecting to the electric vehicle V and charging the in-vehicle battery 9. When the above-described authentication is simultaneously performed on the electric vehicle V that is connected and charged (or contactlessly charged), for example, wired communication is established at the connecting portion of the charging unit 13 and information is transmitted and received. May be.

The network communication unit 14 has a function of establishing communication with the central server 300 via a network line and controlling transmission and reception of information.

The central server 300 corresponds to a charging server, and includes a CPU 31, an urgency determination unit 32, a vehicle train rearrangement processing unit 33, and a network communication unit 34.

Since the CPU 31 and the network communication unit 34 are functionally equivalent to those provided in the charging station 200, description thereof is omitted here.

The urgency determination unit 32 needs to start charging the electric vehicle V as soon as possible based on the remaining charge information (see FIG. 3 described later) of the predetermined electric vehicle V acquired via the charging stand 200. It has a function of determining whether or not a vehicle, that is, a vehicle with a high charge urgency (emergency charge vehicle). In the example of the present embodiment, the electric vehicle V having a remaining charge of 20% or less is generally regarded as an emergency charging vehicle, and these are set as objects to be guided to an emergency standby lane described later (FIG. 4 described later). reference).

The vehicle row rearrangement processing unit 33 is configured so that the vehicle of the electric vehicle V formed in each standby lane L can start charging before the vehicle-mounted battery 9 of the emergency charging vehicle entering the charging station 100 runs out. It has a function of performing changes such as rearrangement of columns (see FIGS. 4 and 6 described later). Furthermore, in this embodiment, it has the function to rearrange so that each electric vehicle V waiting in each waiting lane L may not exceed the upper limit of charging waiting time.

Although not particularly illustrated, the central server 300 can be connected to a charging station of another charging station via the network line NW, and a connection can be established from the central server 300 to a charging station of an arbitrary charging station. Alternatively, the central server 300 establishes a connection in response to a connection request from a predetermined charging station.

FIG. 3 is a diagram for explaining the contents of information transmission / reception between the components in the vehicle charge management system CS1 of the present embodiment.

In FIG. 3, when the electric vehicle V first enters the charging station 100 or is requested at an arbitrary timing from the charging station 200, the in-vehicle navigation device 1 sends vehicle information to the charging station 200 via wireless communication. Send. This transmission function corresponds to vehicle information transmission means. The vehicle information includes vehicle identification information stored in the vehicle information storage unit 3 and remaining charge information of the in-vehicle battery 9 detected via the remaining charge detection unit 8. The data is transmitted to the charging station 200 in association with it. As a result, the charging station 200 that has received this vehicle information has at least the electric vehicle V positioned in a predetermined range near the charging station 200 (in this example, the electric vehicle V forming a train in the corresponding standby lane L). ) Can be identified and the remaining amount of charge can be grasped.

When requested by the central server 300 at an arbitrary timing, the charging station 200 lists the vehicle information of all the electric vehicles V waiting in the corresponding standby lane L, and the vehicle identification information of each electric vehicle V. The information is transmitted to the central server 300 together with the vehicle train information. In addition to the above-described vehicle identification information and remaining charge information, the vehicle information transmitted and received at this time is also transmitted with a charging wait time after the electric vehicle V starts to wait. In this example, the charging stand 200 manages the waiting time corresponding to each electric vehicle V, but the central server 300 may manage it instead (not shown).

Then, the central server 300 receives the vehicle train information indicating the vehicle train status of each standby lane L and the vehicle information of each electric vehicle V from the charging station 200, so that the emergency charging vehicle Ve by the emergency degree determination unit 32 is received. (See FIG. 4 to be described later) and the rearrangement (details will be described later) of the vehicle train by the vehicle train rearrangement processing unit 33 as necessary. Then, the train information newly set based on these processes and the notification information for notifying each electric vehicle V of guidance / warning are transmitted to the charging station 200. In addition to the vehicle identification information of the notification-destination electric vehicle V, the notification information is notified of a standby spot (see FIG. 4 described later) where the electric vehicle V should proceed in response to the setting of the new vehicle train information. Information on the progress spot for warning and warning information for notifying various warnings as necessary.

When the charging station 200 receives the vehicle train information and the notification information from the central server 300, first, the traveling spot information and the warning information are applied to the corresponding electric vehicle V corresponding to the vehicle identification information included in each notification information. Are transmitted by wireless communication. And compared with the setting of new vehicle train information, notification information is repeatedly transmitted with respect to the electric vehicle V which does not follow the said notification information, and formation of an appropriate vehicle train is urged. For the electric vehicle V that is directly connected to the charging unit 13 and performs charging, the vehicle authentication unit 12 performs authentication, and charging is performed only for the electric vehicle V that is legitimately charged at that time. To do.

The in-vehicle navigation device 1 uses the traveling spot information included in the notification information received from the charging station 200, performs guidance display to the corresponding standby spot in the GPS detection unit 4, and outputs warning information to the output unit 7, Notify the driver.

FIG. 4 is a diagram for explaining an example of the rearrangement process of the electric vehicles V by the vehicle charge management system CS1 of the present embodiment.

First, in the example shown in FIG. 4, of the two charging

stations

200n and 200e provided in the charging station 100, the charging station 200n shown in the upper part of the figure mainly charges a normal electric vehicle V having a low charging emergency. The charging station 200e shown in the lower part of the figure is an emergency charging station 200e (corresponding to an emergency equipment terminal) mainly for charging an emergency charging vehicle Ve having a high charging emergency. In this example, the place where the electric vehicle V is connected and charged in the immediate vicinity of the normal charging station 200n is the first power feeding spot E1. The places where the electric vehicle V scheduled to be charged in the subsequent order of the electric vehicle V located at the first power feeding spot E1 sequentially waits are the 1-1 standby spot Wn1, the 1-2 standby spot Wn2, and the first −3 standby spot Wn3, and the row of these 1-1 to 1-3 standby spots Wn1 to Wn3 is the normal standby lane Ln.

The emergency charging station 200e is also provided with the second power feeding spot E2 and the 2-1 to 2-3 standby spots We1 to We3 in the same manner as described above, of which the 2-1 to 2-3 standby spots are provided. The columns We1 to We3 are emergency standby lanes Le. Note that, as described above, in the example of the present embodiment, the electric vehicle V having a remaining charge of 20% or less is regarded as the emergency charging vehicle Ve, and is set as an object to be guided to the emergency standby lane Le. In addition, the electric vehicle V having a remaining charge of more than 20% is regarded as the normal vehicle Vn, and these are set as objects to be guided to the normal standby lane Ln.

In the charging station 100 having such a configuration example, when one emergency charging vehicle Ve is waiting in the emergency standby lane Le, for example, as shown in FIG. 4, waiting for a turn for charging at the second power feeding spot E2. In addition, when another emergency charging vehicle Ve enters, the notification information is transmitted to the emergency charging vehicle Ve just entered, so as to wait at the end of the emergency standby lane Le to guide (see FIG. Inside I: Arrival). That is, basically, in both the normal standby lane Ln and the emergency standby lane Le, the target vehicles are lined up in the order of arrival to form a charge standby vehicle train.

However, as shown in the figure, when the remaining charge of the emergency charging vehicle Ve that is late to enter is relatively small (in this example, the maximum remaining charge is 100% and only the remaining charge is 4%), the vehicle waits at the end as it is. In some cases, power is consumed while the battery is running out and the battery runs out before the start of charging. In this embodiment, when such a determination is made, when charging of the electric vehicle V at the second power feeding spot E2 is completed, there is still a relatively large remaining charge (20% in the illustrated example). Aside from the other emergency charging vehicle Ve of the 2-1 standby spot We1, the emergency charging vehicle Ve of the 2-2 standby spot We2 having the highest charging urgency is interrupted first and headed to the second power feeding spot E2. (II in the figure: interrupt).

In this case, the GPS detection unit 4 of the in-vehicle navigation device 1 of the emergency charging vehicle Ve that performs the interruption can immediately start charging based on the notification information received from the charging stand 200e, for example, as shown in FIG. Along with the explanation to that effect, a guidance image including the position of the host vehicle is displayed that instructs the second power feeding spot E2 to interrupt.

FIG. 6 is a diagram illustrating another example of the rearrangement process of the electric vehicles V by the vehicle charge management system CS1 of the present embodiment.

For example, even when one normal vehicle Vn is not waiting in the normal standby lane Ln, when an emergency charging vehicle Ve newly enters, as shown in FIG. Notification information is transmitted to guide the charging vehicle Ve to wait at the end of the emergency standby lane Le (I in the figure: arrival).

However, from the fact that no normal vehicle Vn is in standby in the normal standby lane Ln and the charging status of each charging

station

200n, 200e at that time, the first 1-1 standby spot in front of the normal standby lane Ln is apparent. When it is known that the electric vehicle V waiting in Wn1 can start the next charging earliest, among the vehicles waiting in the emergency waiting lane Le, the emergency charging vehicle Ve having the highest charging urgency is designated as the normal waiting lane Ln. Is sent to the 1-1st standby spot Wn1 (II in the figure: lane change). Or, for example, when the first power feeding spot E1 is vacant, the emergency charging vehicles Ve are simply arranged in the arrival order in the normal standby lane Ln and the emergency standby lane Le, and the two charging

stations

200n and 200e are arranged. You may make it always use.

FIG. 7 is a flowchart showing a procedure example of processing executed by the central server 300 in the present embodiment. This flow is repeatedly executed after the central server 300 is activated. In the drawings, terms are appropriately abbreviated as appropriate (the same applies to the following flows).

In FIG. 7, first, in step S5, network communication is established with the charging station 200 installed in the charging station 100, and the above-described vehicle train information is received.

Thereafter, the process proceeds to step S10, and it is determined whether or not the total number of electric vehicles V waiting for charging at the charging station 100 has changed by referring to the vehicle train information received in step S5. That is, in this determination, whether or not the total number of the electric vehicles V waiting for charging has increased by the electric vehicle V newly entering the charging station 100 from the previous determination to the present time, and charging Both the determination whether the total number of the electric vehicles V waiting for charging is reduced by the electric vehicle V exiting from the charging station 100 after completion of the process is executed. If the number of electric vehicles V waiting for charging has not changed, the determination is not satisfied, and the routine returns to step S5 and the same procedure is repeated. Even if there is an electric vehicle V newly entered as described above, the first power feeding spot E1 or the second power feeding spot E2 is vacant at that time, and the electric vehicle V is in the first power feeding spot. If charging can be performed immediately after entering E1 or the second power feeding spot E2, the electric vehicle V is not in the “waiting for charging” state, and therefore the total number of the electric vehicles V waiting for charging. There is no change, and the determination in step S10 is not satisfied. On the other hand, if the number of electric vehicles V waiting for charging has changed (increase or decrease), the determination is satisfied, and the routine goes to Step S15.

In step S15, the above-described vehicle information from each electric vehicle V is acquired via the charging station 200 of the charging station 100 (corresponding to a vehicle information acquisition step). That is, as described above, for the electric vehicle V that is in a waiting state for charging after newly entering, the first standby spots Wn1 to Wn3 (in the normal standby lane Ln in which the electric vehicles V are lined up (at the driver's will)) Alternatively, the vehicle information of the newly entered electric vehicle V is acquired via the stand 200n (or the stand 200e) at the second standby spots We1 to We3) of the emergency standby lane Le. In addition, as described above, when the electric vehicle V that has been charged at the first power feeding spot E1 or the second power feeding spot E2 leaves the charging station 100, the vehicle waits for charging in the normal standby lane Ln or the emergency standby lane Le. Even if the electric vehicle V that has been moved to the previous spot by the driver's own will, the stand 200n (or the second standby spot We1, We2) in the new first standby spot Wn1, Wn2 after the advance ( Alternatively, the vehicle information of the electric vehicle V advanced by one spot is acquired via the stand 200e).

Thereafter, the process proceeds to step S20, and an urgent level determination process is performed for determining the charge urgency level of each vehicle based on the vehicle information of each electric vehicle V acquired in step S15. Although not described in detail, the procedure of the emergency level determination process corresponds to the function of the emergency level determination unit 32 of the central server 300 shown in FIG. As described above, in the present embodiment, the electric vehicle V having a remaining charge of 20% or less is regarded as the emergency charge vehicle Ve, and the value of the remaining charge is compared between the emergency charge vehicles Ve. To do. Thereby, even if it is the electric vehicle V from which the urgency level was determined in the previous step S20, the latest urgency level is determined again at this time. As a result, even if the urgency level of the electric vehicle V having a large power consumption ratio compared to other electric vehicles V due to the use state of the air conditioner or the characteristics peculiar to the vehicle suddenly increases as time passes, It becomes possible to respond to changes.

Thereafter, the process proceeds to step S30, the vehicle train information acquired in step S5, the vehicle information of each electric vehicle V acquired in step S15, and the current charge urgency level of each electric vehicle V determined in step S20. Based on the above, it is determined whether or not the current vehicle train needs to be rearranged. If it is not necessary to rearrange the vehicle train, the determination is not satisfied, and the routine returns directly to step S5 to repeat the same procedure. On the other hand, if it is necessary to rearrange the vehicle train, the determination is satisfied, and the routine goes to Step S100. Note that a detailed description of the criteria for determining the necessity of rearranging the vehicle train is omitted. For example, at least one emergency charging vehicle Ve is present in the charging station 100 at that time (in other words, in other words, At this point, the remaining charge of at least one electric vehicle V is 20% or less), and it is predicted that any of the emergency charging vehicles Ve will run out before the start of charging. If it is determined, rearrangement of the vehicle train is necessary. Alternatively, when it is determined that the charging waiting time of any electric vehicle V may exceed a predetermined upper limit value, it may be determined that rearrangement of the vehicle train is necessary.

In step S100, the vehicle train information received in step S5, the vehicle information of each electric vehicle V received in step S15, and the current charge urgency level of each electric vehicle V determined in step S20. Based on this, a vehicle train rearrangement process for instructing an interruption in the standby lane as shown in FIG. 4 or a change in the standby lane as shown in FIG. 6 is performed (see FIG. 8 described later). Note that the sequence of the vehicle train rearrangement process corresponds to the function of the vehicle train rearrangement processing unit 33 of the central server 300 shown in FIG.

Thereafter, the process proceeds to step S35, where it is determined whether there is an electrically charged vehicle V in which the in-vehicle battery 9 runs out due to insufficient charging as a result of the newly set vehicle train by the rearrangement in step S100. If charging of all electric vehicles V is in time for the newly set vehicle train, the determination is not satisfied, and the routine returns to step S5 and the same procedure is repeated. On the other hand, if there is an electric vehicle V that cannot be charged in time, the determination is satisfied, and the routine goes to Step S40. In step S <b> 40, warning information that warns that charging is not in time for the corresponding electric vehicle V is transmitted via the charging stand 200. Then, it returns to step S5 and repeats the same procedure.

FIG. 8 is a flowchart showing a detailed procedure example of the vehicle train rearrangement process in step S100 shown in FIG. As described above, when this process is performed, at this point, at least one emergency charging vehicle Ve exists in the charging station 100.

First, in step S105, the vehicle train information received in step S5 of the flow of FIG. 7 is referred to, and at this time, at least one vehicle (normal vehicle Vn or emergency charging vehicle Ve) waits for charging in the normal standby lane Ln. It is determined whether or not. When no vehicle is waiting in the normal standby lane Ln (that is, when the normal standby lane Ln is empty, including the case where the electric vehicle V exists only in the first power feeding spot E1 and is charged) The determination is not satisfied and the routine goes to Step S110. In step S110, vehicle train information is set so that the emergency charging vehicle Ve having the highest charging urgent degree among the emergency charging vehicles Ve that are waiting in the emergency standby lane Le at this time is changed to the normal standby lane Ln (lane). Equivalent to instruction generation means). Thereafter, the process proceeds to step S140. On the other hand, when the normal vehicle Vn is on standby in the normal standby lane Ln, the determination in step S105 is satisfied, and the routine proceeds to step S115.

In step S115, it is determined whether or not a plurality of emergency charging vehicles Ve are waiting in the emergency standby lane Le at this time. If a plurality of emergency charging vehicles Ve are waiting in the emergency standby lane Le at this time, the determination is satisfied, and the routine goes to Step S120. In step S120, among the plurality of vehicles, the emergency charging vehicle Ve having the highest urgency level at this time is charged in the next order after the charging of the electric vehicle V currently charging at the second power feeding spot E2. (2) The vehicle train information is set so as to preferentially enter the power feeding spot E2. In other words, the emergency charging vehicle Ve having the highest degree of urgency is set to the first priority in the order of waiting for the second power feeding spot E2.

FIG. 11 is a diagram for explaining information transmission / reception contents between components in the vehicle charging management system CS2 of the present embodiment, and corresponds to FIG. 3 in the first embodiment. In addition, since the transmission / reception content of the information between the vehicle-mounted navigation device 1 of the electric vehicle V waiting in each charging station 100 and each charging stand 200 is the same as that shown in FIG. Is omitted.

In FIG. 11, the process of the present embodiment is started when the electric vehicle V that exists outside the charging station 100 transmits a station search request to the central server 300 </ b> A by wireless communication. . The transmission procedure at this time corresponds to a vehicle information transmission step, and the transmission function corresponds to a vehicle information transmission means. For example, only the emergency charging vehicle Ve may be able to transmit the station search request, and the normal vehicle Vn having a sufficient remaining charge amount may not be able to transmit the station search request (hereinafter described based on such assumptions). To do). In addition, when transmitting the station search request, vehicle information is also transmitted. The vehicle information in this case also includes position information indicating the current position of the emergency charging vehicle Ve detected by the GPS detection unit 4 together with the vehicle identification information and the remaining charge information of the emergency charging vehicle Ve. include.

As a result, the central server 300A uses the functions of the travel distance estimation unit 35, the station search unit 36, and the arrival time estimation unit 37 described above, the travelable range of the emergency charging vehicle Ve that has transmitted the station search request, and the travelable range. It is possible to grasp the charging stations 100 existing in the range, the estimated arrival times when heading for them, and the estimated remaining charge at that time.

Next, the central server 300A receives vehicle train information corresponding to the charging station 200 from each charging station 100 searched within the travelable range and each electric vehicle V waiting on the corresponding standby lanes Le and Ln. Get vehicle information. As a result, the central server 300A uses the functions of the vehicle train simulation unit 38 described above, and each vehicle train situation when the emergency charging vehicle Ve that transmitted the station search request arrives at each of the searched charging stations 100. Can be predicted.

Then, referring to the changes in the vehicle train state, a charging station 100 and a charging stand 200 that can start charging before the emergency charging vehicle Ve runs out of batteries are selected. In the example of the present embodiment, only one of the closest charging stations 100 is extracted, and station search result information (corresponding to stand position information) for guiding and guiding the charging station 100 and the charging station 200 is included. The notification information is returned to the emergency charging vehicle Ve via wireless communication. The notification information includes warning information that informs the user when an appropriate charging station 100 and charging station 200 are not found.

That is, when the charging station 100 and the charging stand 200 that can start charging before the battery of the emergency charging vehicle Ve is exhausted, the function of the GPS detection unit 4 of the in-vehicle navigation device 1 that has received the station search result information. Thus, as shown in FIG. 12, for example, a map image indicating a route to the charging station 100 and designation of the charging station 200 are displayed on the output unit 7 together with an explanation that charging can be started immediately. Done. At this time, even if there is a charging station 100 that is closer to the emergency charging vehicle Ve, for example, when a large number of emergency charging vehicles Ve are waiting there and a long charging congestion occurs, the charging station 100 Is not reflected in the station search result information as inappropriate, and the above display is not performed.

In step S235, the notification information including the station search result information for guiding the charging station 100 and the charging station 200 as search results is transmitted to the emergency charging vehicle Ve (corresponding to a notification information output step and a notification information output means). Thereafter, this flow is terminated. On the other hand, if the charging station 100 cannot charge the emergency charging vehicle Ve before the battery runs out due to the amount of charging congestion or the like, the determination is not satisfied and the routine goes to Step S240.

In step S240, it is determined whether or not there is a candidate for the next charging station 100, in other words, whether or not charging for all charging stations 100 is determined before the battery runs out. If there is a candidate for the next charging station 100, the determination is satisfied, the process returns to step S220, and the candidate for the charging station 100 next to the emergency charging vehicle Ve is selected, and the same procedure is repeated. On the other hand, if there is no candidate for the next charging station 100, the determination is not satisfied, and in step S245, warning information for warning that the charging station 100 in time for charging has not been found is transmitted as notification information to the emergency charging vehicle Ve, This flow is finished.

In this way, even before the emergency charging vehicle Ve is connected to the charging stand 200, the central server 300A can grasp the remaining charge amount of the emergency charging vehicle Ve through the charging stand 200. As a result, in the charging station 100, the emergency charging vehicle Ve can be appropriately guided so that the drive stop due to the in-vehicle battery 9 running out can be avoided as much as possible.

In the vehicle charging management system CS2 in the second embodiment, in addition to the above-described configuration, the vehicle information transmission means of the in-vehicle navigation device 1 further searches for the remaining charge information, vehicle position information, and charging equipment. The central server 300A transmits the vehicle information including a request, and the central server 300A determines the remaining charge among the emergency charging vehicles Ve located outside the charging station 100 based on the position information and the remaining charge information included in the vehicle information. When the search request is input from the emergency charging vehicle Ve whose amount is lower than a predetermined threshold, before the vehicle battery 9 runs out of the charging station 100 within the travelable range of the emergency charging vehicle Ve, Search means for searching for a charging station 200 of the charging station 100 capable of starting charging of the emergency charging vehicle Ve, The intelligent information output means outputs the notification information including the charging station 200 stand position information searched by the search means, and the GPS detection unit 4 of the in-vehicle navigation device 1 receives the notification information output means from the notification information output means. Based on the notification information, guidance is performed along the stand position information.

In FIG. 14, the process of the present embodiment is as follows. The electric vehicle V existing outside the charging station 100 transmits a station determination request (corresponding to a conformity determination request) to the central server 300A by wireless communication. It is started as a trigger. This transmission function corresponds to vehicle information transmission means. In the present embodiment, it is assumed that only the emergency charging vehicle Ve can transmit the station determination request, and the normal vehicle Vn having a sufficient remaining charge capacity cannot transmit the station determination request. Further, when transmitting this station determination request, the operator needs to know the presence of the desired charging station 100 in advance by using the GPS detection unit 4 or the like, and designate the charging station. The determination request includes identification information of the specific charging station 101 (see FIG. 15 described later). Further, when transmitting the station determination request, vehicle information including the position information of the emergency charging vehicle Ve is also transmitted.

As a result, the central server 300A can determine the travelable range of the emergency charging vehicle Ve that has transmitted the station determination request by the functions of the travel distance estimation unit 35, the station search unit 36, and the arrival time estimation unit 37 described above. At this time, it can be determined whether or not the emergency charging vehicle Ve can reach the designated charging station 101. If it can be reached, the estimated arrival time when heading to the designated charging station 101 and the estimated remaining charge at that time can be grasped.

Next, the central server 300A acquires vehicle train information and vehicle information of each electric vehicle V that is on standby from the designated charging station 101. Thus, the central server 300A can predict a change in the vehicle train state when the emergency charging vehicle Ve that has transmitted the station determination request arrives at the designated charging station 101 by the function of the vehicle train simulation unit 38 described above. Then, with reference to the change in the vehicle train state, it is possible to determine whether or not charging can be started before the battery runs out when the emergency charging vehicle Ve heads for the designated charging station 101. In the present embodiment, the designated station determination result information includes a determination result including whether or not the designated charging station 101 of the emergency charging vehicle Ve can reach the charging station 200 and whether or not charging can be started before the battery runs out when the emergency charging vehicle Ve can be reached. (Corresponding to the determination result information), and notification information including this is returned to the emergency charging vehicle Ve via wireless communication. Note that this notification information includes warning information that informs the user when it is not reachable or when it is impossible to start charging before the battery runs out.

The GPS detection unit 4 of the in-vehicle navigation device 1 outputs the station determination result information and the warning information included in the notification information received from the central server 300A to the output unit 7, and notifies the driver by visual display and sound. That is, when it is possible to reach the designated charging station 101 and charging can be started before the battery runs out, the function of the GPS detection unit 4 of the in-vehicle navigation device 1 that has received the station determination result information, for example, FIG. As shown in FIG. 5, a map image indicating a route to the charging station 100 and designation of the charging station 200 are displayed on the output unit 7 together with an explanation that charging can be started immediately, and guidance is performed. In the example shown in FIG. 15, the output unit 7 of the in-vehicle navigation device 1 is configured with a touch panel, and the operator directly contacts one of the charging stations 100 displayed on the map image, as described above. A state where the designated charging station 101 is designated is also shown.

FIG. 16 is a flowchart showing a procedure example of processing executed by the central server 300A in the present embodiment. This flow is started when the central server 300A receives a station determination request including information on the designated charging station 101 from the emergency charging vehicle Ve existing outside the charging station 100.

In FIG. 16, in step S305, the vehicle information is received from the emergency charging vehicle Ve that transmitted the station determination request (corresponding to a vehicle information acquisition step). In the present embodiment, as in the second embodiment, the emergency charging vehicle Ve that can transmit the station determination request may be determined by the in-vehicle navigation device 1 of the electric vehicle V, or the central server 300A. May be determined based on the vehicle information.

Thereafter, the process proceeds to step S310, the travelable range of the emergency charging vehicle Ve is obtained based on the remaining charge included in the vehicle information received in step S305, and the emergency charging vehicle Ve is designated as the designated charging station 101 (station determination request). In addition, it is determined whether or not it can be reached (corresponding to a determination step and determination means). If not reachable, the determination in step S310 is not satisfied, and in step S315, warning information for warning that the designated charging station 101 cannot be reached is transmitted as notification information to the emergency charging vehicle Ve, and this flow is ended. On the other hand, if the emergency charging vehicle Ve can reach the designated charging station 101, the determination is satisfied, and the routine goes to Step S320.

In step S320, vehicle train information and all vehicle information are received from the designated charging station 101.

Thereafter, the process proceeds to step S325, where an estimated arrival time of the emergency charging vehicle Ve to the designated charging station 101 is obtained, and a change in the vehicle train status of the designated charging station 101 at that time is simulated (corresponding to vehicle train prediction means). ).

Then, the process proceeds to step S330, and it is determined whether or not the emergency charging vehicle Ve can start charging at the designated charging station 101 before the battery runs out based on the change in the vehicle train situation simulated in step S325. If charging is possible before the battery runs out, the determination in step S330 is satisfied, and the station determination result indicating that the designated charging station 101 can be reached in step S335 and charging can be started before the battery runs out. Information is transmitted as notification information to the emergency charging vehicle Ve (corresponding to a notification information output step and notification information output means). Thereafter, this flow is terminated.

On the other hand, when the designated charging station 101 cannot charge the emergency charging vehicle Ve before the battery runs out due to a charging congestion amount or the like, the determination in step S330 is not satisfied, and the process proceeds to step S340. In step S340, warning information that warns that the designated charging station 101 can be reached but is not in time for charging before the battery runs out is transmitted as notification information to the emergency charging vehicle Ve, and this flow is terminated.
