Description

Timer management method and program for vehicle charging station

The present invention relates to a timer management method and program for a smartphone used for efficiently using a charging station of an electric vehicle or a PHV (plug-in hybrid vehicle).

With the widespread use of electric vehicles and PHVs (hereinafter collectively referred to as electric vehicles), the installation of charging stations in public places such as parking lots in shopping centers is progressing.

Charging an electric vehicle is basically performed at home or in a storage place at night, and charging outside the home is often a highly urgent case. For example, when the process is suddenly changed, or when the battery is consumed more than expected due to excessive power consumption, aging of the battery, or traffic congestion.

However, since the number of charging stations is not sufficient, in order to appropriately cope with the emergency charging described above, a technique for efficiently searching for an empty charging station nearby at that time is necessary. Techniques for searching for and making reservations for usage status of nearby charging stations using smartphones and car navigation devices are known (for example, Patent Document 1 and Patent Document 2). However, since there is still a possibility that a plurality of users try to use the charging stand at the same time, it is necessary to make the waiting time at that time as predictable as possible.

Unlike the case of gasoline refueling, it is unlikely that people are always watching while charging the car, so the user may leave the car and go shopping or eat while charging. If the user does not return after the completion of charging, the charging slot may be occupied by the vehicle even after the completion of charging, and a situation may occur in which the next user waits more than necessary. Predicting this waiting time in advance may improve the convenience for the user and improve the utilization rate of the charging station.

(Needs for simplified charging stand)
Many of the charging stations currently in use often have input / output functions such as input buttons and a liquid crystal display on the charger. As the function of the charger improves, the input / output function may become more sophisticated. However, since the charger is often placed outdoors and used for a long period of time, its mechanical complexity should be minimized from the viewpoint of improving reliability and maintainability. It is not desirable to have a display device or an input device. This is especially important when installing in a place where careful maintenance work cannot be performed. Therefore, a solution that excessively increases the complexity of the equipment of the charging station facility should be avoided in solving the above problem.

FIG. 3 shows an outline of data items managed in the database managed on the management server (103). The management server (103) manages information related to a plurality of chargers (102), information related to a plurality of users, and a plurality of vehicles. The user registers in advance a part of the user-related data and the vehicle-related data by a predetermined registration method, and maintains and manages it as necessary. In addition, the charging stand system operator registers a part of the charger related data in advance and maintains and manages it as necessary.

(Charger related data)
The management server (103) includes, as charger-related data, charger ID, charger location information, charger attribute information, charging slot status, charger status, user ID being used or reserved, Maintain and manage information such as partner stores for discount services.

The charger ID is an identifier that uniquely identifies the charger, and is the same as that described in an identification tag (typically a two-dimensional barcode) provided in the charger controller. The position information is information relating to the physical installation location of the charger, and the attribute information is information relating to specifications of the charger plug and the like. The position information and attribute information are input and maintained in advance by the system administrator.

The charging slot status is information indicating whether or not the vehicle occupies the charging slot, and can be grasped by the management server (103) inquiring to the charger controller (101) via the network (105). The presence / absence of the vehicle may be determined by analyzing an image taken by the camera of the charger controller (101), or a known technique such as a loop coil may be used.

The charger status takes values of at least “free”, “reserving”, “charging”, and “charging completed”. The charger status can be grasped when the management server (103) inquires to the charger controller (101) via the network (105) and inquires of the charger (102) to which the charger controller (101) is connected.

The in-use user ID is an identifier of the user who is currently using the charging station.

The scheduled return time is a time calculated based on the timer time set by the user who is using the charger (or the maximum usage time preset as a value unique to the charger). It is the time that is likely to be available next.

(User-related data)
The management server (103) includes user-related data such as user ID, user authentication information, billing information, user attributes, user status, charger ID in use, message destination, and vehicle ID. Maintain and manage information.

The user ID is an identifier for uniquely identifying the user, and is registered in advance by a predetermined registration procedure. The user authentication information is information necessary for determining that the user is a valid user such as a password. User authentication is performed by a known method such as password check or biometric authentication. The billing information is the data required to charge the charging system usage fee to the user, but in practice, a part of it is maintained and managed by a net service provider that provides an external credit card transaction service. Is desirable.

The user status is data indicating that the user is not reserving, charging, or charging the charging station, and is dynamically updated by the management server (103).

The message transmission destination is address information necessary for sending a message or mail to the user, and is registered by the user at the time of user registration.

The vehicle ID is an identifier of a vehicle that a user may use, and one user may correspond to a plurality of vehicles (conversely, a plurality of users may correspond to one vehicle. is there).

(Vehicle related data)
In the charging system according to the present invention, management for each user may be performed, but in addition, management of the vehicle may be performed. For example, when a plurality of users share one vehicle, privilege information can be collected. In addition, it can be determined whether the vehicle occupying the vehicle slot belongs to a user who is properly registered.

The vehicle ID is an identifier that uniquely identifies the vehicle. The user may register in advance, or may be automatically assigned by a program running on the management server (103). The vehicle registration number is a license plate number.

The vehicle attribute is information on the compatibility of the charging plug, and is registered in advance by the user. When the management server (103) provides information on charging station candidates in response to inquiries from the mobile device (104), it provides information on only charging stations that can be charged by matching vehicle attributes and charger attributes. It is desirable to do.

The user ID is an identifier of one or more users registered in advance as a possibility of using the vehicle. You may check whether the user ID of the actual user and the user ID associated with the vehicle ID match, but there is no need to prohibit the use of the charging period just because they do not match. . This is because there may be cases where another person's vehicle is temporarily rented and charged.

(Charging station emergency reservation process)
FIG. 4 shows a process flow until the user makes an emergency reservation for the charging station and uses the charging station in the electric vehicle charging system according to the present invention.

(S401) A user who needs to use a charging station in his / her neighborhood has received a request to that effect via the mobile terminal (104), and the positioning function of the mobile terminal It is transmitted to the management server (103) together with the position.

(S402) Based on the current position of the portable terminal (104) and the charger status managed by the charger database, the management server (103) obtains position information of one or more charging stations that are candidates for use from the portable terminal (104). ) Here, the charger attribute information managed by the charger database and the vehicle attribute information managed by the vehicle database can be confirmed, and only the charging station information compatible with the vehicle used by the user can be transmitted. desirable. Furthermore, additional information such as fees, nearby facilities, nearby affiliated stores, etc. may also be transmitted. In addition, the management server (103) checks whether a vehicle is present in the charging slot (vehicle stop space) even though the charging stand is empty, using a camera provided in the charger controller (101), If there is a vehicle, a warning message may be sent to the portable terminal (104).

(S403) The mobile terminal (104) displays nearby free charging station candidates based on the data transmitted from the management server (103). It is desirable that the display is overlapped on the map. The user selects one charging station he / she wants to use from among the candidates, and the portable terminal (104) transmits the selection to the management server (103). If an urgent reservation is not required, a message to that effect may be sent. In order to prevent the abuse of the emergency reservation function, an additional fee will be collected for the emergency reservation, or a penalty fee will be charged if the charger is not charged within the specified time despite the emergency reservation. You may make arrangements such as collecting

(S404) The management server (103) transmits a command to make a reservation state to the charger controller (101) corresponding to the charging station selected by the user, and uses the status of the charger in the charger database. Make it inside.

(S405) The charger controller (101) that has received the reservation reservation command temporarily stops the use of the connected charger (102), lights up the reservation display lamp, and This indicates that the battery charger (102) is urgently reserved and can only be used by the reservation person. As a result, the user who made the emergency reservation can use the charger immediately and reliably when the user arrives at the reserved charger location. In addition, the flap of the charging slot may be controlled so that vehicles other than the vehicle that made the reservation cannot physically enter the charging slot.

(S406) When the user who made the emergency reservation arrives at the target charging station, the user reads the identification tag of the charging controller (101) using the barcode reading device (usually a camera) of the portable terminal (104), The identifier of the charging controller is transmitted to the management server (103) together with the user ID.

(S407) The management server (103) reads the message sent from the mobile terminal (104), confirms that the user ID is the same as the user who reserved the charge controller, and if it is the same Changes the status of the charger database in use and sends a command to the charger controller (102) to make the charger (103) available. If the user ID sent from the mobile device (104) does not match the user who reserved the charge controller (for example, if the user accidentally arrives at another charging station), an error message will be displayed on the mobile device It is desirable to return to (104).

(S408) Upon receiving the command from the management server (103), the charger controller (101) turns off the reservation display lamp and makes the connected charger (102) available. In addition, when the vehicle cannot enter the charging slot due to the flap, the flap is returned.

When charging is completed, the charger controller (101) that has received the charging completion status from the charger (102) transmits a notification of charging completion to the management server (103). In response to this, the management server (103) changes the charger status to charging completion. The management server (103) opens the charging slot for the portable terminal (103) of the user of the vehicle when the vehicle remains in the charging slot even after a predetermined time has elapsed since the completion of charging. A command for displaying a warning message may be transmitted. In addition to this (or instead of this), a warning sound may be generated from the charger controller (101). For users who occupy the charging slot more than necessary even after the completion of charging, an arrangement having an effect of inhibiting the occupation, such as charging an additional charge or invalidating the discount, may be made.

(Anonymous contact process for charging users)
Since it takes time to charge the electric vehicle, there may be a case where the driver goes out for shopping while charging. In this case, even if the charging is completed, the driver does not return to the charging slot, and a state in which the driver occupies the place occurs, which may adversely affect the usage rate of the charger and customer satisfaction. Such an act may be suppressed by charging as a penalty for occupying more charging slots than necessary. As an additional means, it is desirable that there is a mechanism in which a person who desires to use the charging station contacts the driver of the occupied vehicle, asks for an approximate time to return, or promptly returns. Here, since both drivers are not usually acquainted with each other, it is not desirable to have a mechanism in which the other party can know the mail address and message address. In addition, since it is a short time until the previous driver returns to the charging slot that needs to be exchanged, it is desirable that the exchange be possible only during that time. FIG. 5 shows the process flow of such anonymous and timed communication.

(S501) The user 1 reads the identification tag of the charger controller (101) using the portable terminal 1 (104), and transmits it to the management server (103) together with the ID of the user 1. Note that this may be a part of the above-described emergency reservation flow or normal use without reservation.

(S502) The management server (103) confirms that the user 1 is a valid user, and stores the ID of the user 1 in the “user ID in use” field of the record in the charger database.

(S503) The user 2 who wants to use the same charger reads the identification tag of the charger controller using the portable terminal 2, and the ID of the user 2 and the driver of the vehicle being charged (ie, use) To the management server (103) together with a message to be transmitted to the user 1).

(S504) The management server (103) confirms that the user 2 is a legitimate user, and then uses the “in-use user ID” of the charger record to send the email address of the user 1 from the user database. (Or message destination) is obtained, and the message sent by the user 2 is transmitted to the destination. Personal information such as the telephone number or mail address of the other party is never known between the user 1 and the user 2.

(S505) The user 1 who has received the anonymous message at the portable terminal 1 (103) sends a reply if necessary. The reply message is sent by the management server (103).

(S506) The management server (103) transmits the received reply message to the mobile terminal 2 of the user 2.

(S507) The user 2 who has received the message can further reply. This process of sending and receiving messages can be repeated as necessary.

User 2 (or a user other than User 1) has started using the charger station, or has confirmed that the vehicle of User 1 has left the charging slot with the camera of the charging controller (101). When it is determined that the occupation state of the user 1 has been eliminated, the management server (103) ends the provision of the mail (message) transfer function between the user 1 and the user 2.

(Timer sharing function)
In place of or in addition to the above communication function between users, a timer sharing function between charging station users is provided, and multiple times at which the charger is likely to be used are used. It is desirable that people can share.

A screen example of the information terminal (104) providing the timer sharing function is shown in FIG. When a specific charging station is searched, information on the station (business hours, type and number of connectors, word-of-mouth information on the station, estimated waiting time, etc.) is displayed. It is also possible to enter information and word-of-mouth whether or not the charging station was available. The input information may be stored and managed by the management server (103), stored or managed by another website, or made available to other users using a general social network. . The message “30 minutes remaining” in FIG. 6 is set by the user who is currently using the charger (or set as a predetermined value unique to the charger) stored in the management server (103). It means that it is 30 minutes until the scheduled return time. This message should be updated from time to time.

FIG. 7 shows an example of a flow for sharing a waiting time timer according to the present invention. The setting of the scheduled return time does not have to be compulsory systematically, and is preferably performed as a voluntary action by the user.

(S701) It is assumed that a user (user 1) of the mobile terminal 1 uses a certain charge controller. First, as described above, the user 1 reads the identification tag of the charge controller and transmits the read identifier of the charge controller to the management server (103).

(S702) The management server (103) performs the necessary checks, and if the user 1 has usage authority, sets the charging controller in a chargeable state.

(S703) The user starts charging. Then, the mobile terminal 1 is used to input the scheduled time for returning to the charging station. This is also for my own reminders. Input may be made by numerical input or selected from a list. In general, it is common to use a smartphone as an alternative to an alarm clock and set an alarm at a specific time, which is highly convenient for the user himself, so the user may perform this operation. high. The portable terminal 1 transmits this timer setting information to the management server (103). Although it is not possible in the system to force the user 1 to return to the charging station according to the timer setting time, it may be left to the good intentions of each user, or it did not return according to the timer setting time (the vehicle charging was terminated). If not, an arrangement may be made that gives some penalty (for example, reduction of privilege points, demotion from good member status). Users who do not perform full charge can set the scheduled return time earlier than the full charge completion time (this allows other users who want to use the charger to fully charge the charger. That you ’ll be able to use it faster than if you had Setting the scheduled return time after the time when the full charge is completed may or may not be prohibited as a program logic (if not, the above-mentioned penalty may be used to prevent long-term exclusive use of the charging slot. It ’s desirable to make arrangements). Further, when the user does not input the scheduled return time, the scheduled return time may be set based on a value (for example, the longest charging time) determined as a value unique to the charger.

(S704) The management server (103) can store the sent timer setting information (scheduled return time) in a temporary storage area (corresponding to the scheduled return time of the charger related data in FIG. 3) and provide it to other users. To.

(S705) Assume that another user who wants to use the charger and uses the portable terminal 2 searches for the charger from the portable terminal 2 and requests related information display.

(S706) The management server (103) transmits the timer information stored in S704 as a part of the information included in the charger-related data to the portable terminal 2.

(S707) The mobile terminal 2 displays a predicted value of how many minutes the charger can be used based on the scheduled return time transmitted from the management server (103) as the estimated waiting time of the charger. To do. An example of this timer display is shown in FIG. The predicted value may be indicated by time or may be indicated by remaining time. Instead of the scheduled return time set by the user (or the time “minutes” calculated based on the return time) itself, the time / time taking into account some error may be displayed. When a plurality of charge controllers are installed in one charging stand, timer information may be displayed for each charge controller, but only the shortest waiting time may be displayed. In addition, when one or more other users have made a reservation before the user of the mobile terminal 2 performs a search, the average charging station occupancy time of those users or the charging station It is desirable to add the predetermined maximum occupation time to the waiting time. The user 2 refers to the predicted value at which the charging station can be used and the estimated time until the charging station arrives, and decides whether or not to go to the charging station (for example, another charging station). To make a reservation) or to make a reservation. As a result, the charger is idle without the other user knowing the fact that the previous user (user 1) is likely to terminate the charger before full charge and the charger is likely to be usable. The situation where the battery charger is in the state, and even though the charger was expected to be vacant, the target charger was still in use and the previous user (user 1) It is possible to minimize the situation that must wait for the return.

(Remarkable technical effect of the present invention)
According to the present invention, without using a complicated input device or display device in the charger controller, and without a complicated scheduling mechanism, the utilization rate of the electric vehicle charging station can be improved and the convenience of the user can be improved. Can be increased. Moreover, in realizing this effect, the manufacturing and maintenance costs of the charger controller can be reduced, and even a charger controller installed outdoors can maintain high reliability. Also, since most of the functions are executed by the application program on the smartphone and the application program on the management server, it is easy to add a new function without changing the charger controller.
