<Overall configuration of EV charge management system>
FIG. 1 is a diagram showing an example of the overall configuration of an EV charge management system 1 according to the present embodiment. The EV charge management system 1 according to the present embodiment includes an EV management server 100, a charge management server 200, a charge management server 300, a user terminal 400, and an EV 500. The EV 500 is an electric vehicle (including a plug-in hybrid vehicle). In other words, the EV 500 is a vehicle that travels using a rechargeable battery.

  The EV management server 100 is a server device that manages the EV 500. More specifically, the EV management server 100 is a server device of an automobile company that manufactures or sells the EV 500, for example. The EV management server 100 identifies information (for example, the name and address of the user) of a user who uses the EV 500 (hereinafter referred to as “user”) and information about the vehicle of the EV 500 (for example, to identify the EV 500). Various information such as a vehicle ID assigned to each EV 500 and a model of the EV 500 is managed for each EV 500. In addition, the EV management server 100 acquires position information of the EV 500, information related to charging of the EV 500, and the like from the EV 500 at all times (for example, every 5 minutes) or as necessary via a network such as the Internet.

  In other words, EV 500 position information is information indicating the position of EV 500. This information is constantly acquired and recorded by the EV 500, and the EV management server 100 always acquires the position information according to the passage of time. As a result, the movement history (that is, the movement route) of the EV 500 is grasped. That is, the position information of the EV 500 can be grasped as information related to the movement history of the EV 500.

The information related to the charging of the EV 500 includes, for example, the amount of charging power charged to the EV 500 by the charging facility, the number of times of charging, the charging time, the model of the EV 500, the battery capacity of the rechargeable battery 501 of the EV 500, and the amount of charging power of the rechargeable battery 501. Information (SOC (State Of Charge)), deterioration state of the rechargeable battery 501, and the like. By constantly acquiring these pieces of information, changes in the charging status of the EV 500 over time can be grasped. Note that unique information such as the EV 500 vehicle type and the battery capacity of the rechargeable battery 501 of the EV 500 may be registered in advance in the EV management server 100.
In the present embodiment, EV management server 100 is used as an example of a management server that manages a vehicle that runs using a rechargeable battery.

The charge management server 200 is a server device that manages charging for the EV 500. More specifically, the charge management server 200 is a server device of an electric power company that provides power to the EV 500, for example. The charging management server 200 acquires EV 500 position information and information related to charging of the EV 500 from the EV management server 100 via a network such as the Internet. And the charge management server 200 grasps | ascertains how much the user user charged with the specific charging equipment based on the information acquired from the EV management server 100. FIG. The grasped information is output to the fee management server 300.
In the present embodiment, charge management server 200 is used as an example of a vehicle charge management system.

  The fee management server 300 is a server device that manages a fee charged to a user. More specifically, the charge management server 300 is, for example, a server device of a management company of a charging facility that charges the EV 500, or a server device of a collective housing management association in which the charging facility is installed. The charge management server 300 acquires information indicating how much the user user has charged at the charging facility from the charge management server 200 via a network such as the Internet. Then, the fee management server 300 calculates a fee to be charged to the user based on the acquired information, and outputs the calculated fee information to the user terminal 400.

  The user terminal 400 is a computer device used by a user. Examples of the user terminal 400 include a portable information terminal (so-called smartphone, tablet terminal, etc.), a PC (Personal Computer), and the like. The user terminal 400 acquires information on a fee charged to the user from the fee management server 300 via a network such as the Internet. Then, the user terminal 400 displays the acquired fee information on the screen and notifies the user of use.

  The EV 500 includes a rechargeable battery 501, a charging circuit 502, and an on-vehicle device 503. Here, the EV 500 is connected to a charging facility installed in an apartment house or the like via a charging plug or the like. Then, power is supplied to the rechargeable battery 501 from the charging facility via the charging circuit 502. The rechargeable battery 501 is charged with the power supplied from the charging circuit 502 and supplies the charged power to the EV 500. Moreover, the onboard equipment 503 communicates with other apparatuses, such as EV management server 100, and outputs the positional information on EV500 acquired by GPS (Global Positioning System), and the information regarding charge of EV500.

  Note that the position information is not limited to the configuration acquired by the GPS. For example, the vehicle-mounted device 503 of the EV 500 may grasp the position of the EV 500 by performing wireless communication with a surrounding wireless device. Alternatively, the surroundings may be photographed with a camera provided in the EV 500 and the photographed image may be transmitted to the EV management server 100. Furthermore, it is conceivable that the charging facility transmits information on the EV 500 to the EV management server 100. For example, by providing a camera in the charging facility, photographing the EV 500 with the camera, and transmitting the photographed image to the EV management server 100, it is understood that the EV 500 is at the charging facility.

  In the example illustrated in FIG. 1, one EV management server 100, one charge management server 200, one charge management server 300, one user terminal 400, and one EV 500 are shown. However, the number of devices is not limited to one. For example, the user terminal 400 exists for each user. For example, the fee management server 300 exists for each charging facility having one or a plurality of chargers. Further, for example, regarding the EV 500, there are the number of EVs 500 sold by an automobile company.

Further, the information stored in each device is not limited to the example described above. For example, in the above-described example, the user information is stored in the EV management server 100, but may be stored in the charge management server 200, the charge management server 300, or the like. In this case, in the charge management server 200, the charge management server 300, and the like, for example, the vehicle ID is associated with the information on the user (that is, information on the user who uses the EV 500 to which the vehicle ID is assigned). . On the other hand, in the EV management server 100, for example, for each EV 500, the vehicle ID and other information (for example, the vehicle type of the EV 500, the position information of the EV 500, and information related to charging of the EV 500) are associated. Therefore, when acquiring information on the EV 500 from the EV management server 100, the charge management server 200 acquires the information on the EV 500 used by the user by specifying the vehicle ID associated with the user. Is possible.
In addition, although vehicle ID and the user's information were linked | related here, the information which can identify EV500, and the user's information should just be tied, and it is not restricted to the structure which uses vehicle ID.

<Hardware configuration of charge management server>
Next, a hardware configuration of charge management server 200 according to the present embodiment will be described. FIG. 2 is a diagram illustrating a hardware configuration example of the charge management server 200 according to the present embodiment. The hardware configuration shown in FIG. 2 is used as an example of the hardware configuration of the EV management server 100, the charge management server 300, and the user terminal 400.

  As illustrated, the charge management server 200 includes a CPU (Central Processing Unit) 201 that controls the entire apparatus through execution of a program (including firmware), and a ROM that stores programs such as a BIOS (Basic Input Output System) and firmware. (Read Only Memory) 202 and RAM (Random Access Memory) 203 used as a program execution area.

The charge management server 200 includes an HDD (Hard Disk Drive) 204 that is a storage area for storing various programs such as an OS (Operating System) and applications, input data for various programs, output data from various programs, and the like. The program stored in the ROM 202, the HDD 204, or the like is read into the RAM 203 and executed by the CPU 201, thereby realizing the function of the charge management server 200.
Furthermore, the charge management server 200 includes a communication interface (communication I / F) 205 for performing communication with the outside, a display mechanism 206 including a video memory and a display, an input device 207 such as a keyboard, a mouse, and a touch panel. Is provided.

<Functional configuration of charge management server>
Next, the functional configuration of the charge management server 200 according to the present embodiment will be described. FIG. 3 is a diagram illustrating an example of a functional configuration of the charge management server 200 according to the present embodiment. The charge management server 200 includes a target user extraction unit 211, a target user information acquisition unit 212, a charging power amount calculation unit 213, a charging information generation unit 214, and a charging information output unit 215.

The target user extraction unit 211 accesses the EV management server 100 and extracts a usage user (hereinafter, referred to as “target user”) that is a target of charge calculation.
For example, the target user extraction unit 211 specifies a charging facility (hereinafter, referred to as “target charging facility”) that is a target of charge calculation. Then, the EV management server 100 is accessed, and all users who are determined in advance to use the specified target charging facility are extracted as target users.

In addition, the use user predetermined as using the target charging facility is, for example, a user who has been registered as using the target charging facility, a user who has contracted with a management company that manages the target charging facility, or the like. is there.
More specifically, for example, the target user extraction unit 211 specifies the charging facility of the apartment A as the target charging facility. And all the use users (for example, all the use users who live in the apartment A) registered as what uses the charging equipment of the apartment A are extracted as an object user.

  Here, the information on the charging facility existing in each place may be stored in the EV management server 100, or may be stored in the charge management server 200 or another device. In addition, information on a user who is determined in advance to use the target charging facility may be stored in the EV management server 100, or may be stored in the charge management server 200 or another device.

  In addition, as described above, the user information may be stored in the charge management server 200, the charge management server 300, and the like, but may not be stored in the EV management server 100. In this case, the target user extraction unit 211 accesses the charge management server 200, the charge management server 300, and the like, and extracts all the usage users that are determined in advance as using the target charging facility as target users.

The target user may be extracted at least once a month when, for example, charging is performed in units of one month. However, the latest charging state is grasped by performing more frequently.
Furthermore, a range in which the charge management server 200 can access the EV management server 100 is determined in advance. For example, the name and address of the user are defined as accessible information, while the telephone number and date of birth of the user are defined as inaccessible information.

The target user information acquisition unit 212 accesses the EV management server 100 and acquires position information of the target user's EV 500 and information related to charging of the EV 500 for the target user extracted by the target user extraction unit 211. As described above, when the user information is stored in the charge management server 200, the charge management server 300, or the like, the target user information acquisition unit 212 specifies the vehicle ID or the like associated with the target user. Thus, the position information of the target user's EV 500 and information related to charging of the EV 500 are acquired.
Here, the target user information acquisition unit 212 acquires position information of the target user's EV 500 and information related to charging of the target user's EV 500 in the target period. For example, when charging is in units of one month and the target user is extracted once a month, the target user information acquisition unit 212 starts counting from the end of the last month that was the last charging target. 1 month as the target period. Then, for this target period, EV 500 position information and information related to EV 500 charging are acquired.

The charging power amount calculation unit 213 calculates the charging power amount charged by the target user to the EV 500 at the target charging facility.
Here, based on the position information of the target user's EV 500, the charging power amount calculation unit 213 identifies a time zone in which the EV 500 was at the location of the target charging facility (hereinafter referred to as a “chargeable time zone”). Then, based on information related to charging of the target user's EV 500, the charging power amount calculation unit 213 calculates the charging power amount of the charging of the EV 500 performed in the chargeable time zone.
Note that the time zone in which the EV 500 was at the location of the target charging facility is, for example, the time zone in which the EV 500 was in a predetermined range from the target charging facility (for example, a range having a radius of 5 m from the target charging facility).

FIG. 4 is a diagram for explaining an example of a process for calculating the amount of charging power charged in the EV 500 in the chargeable time zone.
Here, as the information related to the charging of the EV 500, when the charging power amount charged in the EV 500 is sent from the EV management server 100, the charging power amount charged in the chargeable time zone is directly calculated from the information. Calculated.
For example, as shown in FIG. 4A, it is specified that EV500 was in apartment A by 12:00 to 20:00 on December 2, 2018, based on the position information of EV500. In this case, 12:00 to 20:00 on December 2, 2018 is a chargeable time zone in the apartment A. Here, it is assumed that the EV management server 100 has sent information indicating that the amount of charging power from 12:00 to 15:00 on December 2, 2018 is 5 kWh. Thereby, the charge electric energy charged in the condominium A is calculated as 5 kWh on December 2, 2018 from 12:00 to 15:00.

On the other hand, as the information related to the charging of the EV 500, when the amount of charging power charged in the EV 500 is not sent from the EV management server 100, the charging is indirectly performed in the chargeable time zone based on other information. The amount of charged power is calculated. For example, the amount of charge power charged in the chargeable time zone is indirectly calculated based on a change in the remaining amount of charge power of the rechargeable battery 501.
For example, as shown in FIG. 4B, it is specified that EV 500 was in apartment A by 12:00 to 15:00 on December 2, 2018, based on position information of EV 500. In this case, 12:00 to 15:00 on December 2, 2018 is a chargeable time zone in the apartment A. Here, the information on the remaining amount of charging power over time sent from the EV management server 100 specifies that the remaining amount is increasing from 14:00 to 15:00 on the same day. Thereby, it is grasped | ascertained that the charge was performed in the apartment A from 14:00 to 15:00 on December 2, 2018. Further, since the remaining amount of charge power is increased from 0% to 90%, for example, when the battery capacity of the rechargeable battery 501 of the EV 500 is 10 kWh, the charged charge energy is calculated as 9 kWh.

Furthermore, by setting the amount of charge power that can be charged per unit time as a provisional value, multiplying that value and the charge time, indirectly, the amount of charge power charged in the chargeable time zone You may calculate. For example, in the example shown in FIG. 4B, the charging time is specified as 1 hour. Here, if the chargeable electric energy that can be charged per unit time is set to 9 kWh, even if the percentage (%) of the remaining amount of the charged electric energy is not accurately grasped, the charged electric energy that is charged is Calculated as 9 kWh.
Here, the provisional value of the charge power amount that can be charged per unit time may be changed according to the model of the EV 500, the performance of the rechargeable battery 501, the battery capacity, or the like. Moreover, you may change the temporary value of the charge electric energy which can be charged per unit time according to the residual amount of the charge electric energy at the time of a charge start.
In this way, the amount of charging power charged in the chargeable time zone is indirectly calculated.
In the present embodiment, the charging power amount calculated by charging power amount calculation unit 213 is used as an example of the degree of charging.

The billing information generation unit 214 generates billing information for charging the target user according to the amount of charging power charged to the EV 500 by the target user at the target charging facility.
Here, the billing information generation unit 214 acquires the charging power amount calculated by the charging power amount calculation unit 213 for all target users who use the target charging facility. Then, the billing information generation unit 214 generates billing information for each target user related to the target charging facility based on the charging power amount of all target users. For example, the charging information generation unit 214 generates a charging power amount ratio (that is, a charging ratio) of each target user in the target charging facility as charging information of each target user regarding the target charging facility.

  The billing information output unit 215 outputs billing information of the target user to the fee management server 300 that manages the target charging facility.

More specifically, when the charge management server 300 receives the charge information from the charge information output unit 215, the charge management server 300 calculates a charge for charging each target user. For example, the charge management server 300 calculates the charge to be charged to each target user by apportioning the EV charge service charge according to the ratio of the charge power amount of each target user. Then, the fee management server 300 outputs the calculated fee information to the user terminal 400 of each target user. As a result, each target user is notified of information on a fee charged for charging the EV 500 at the target charging facility.
The EV charging service fee is a fee imposed on the target charging facility. More specifically, the EV charging service fee is a service fee determined in accordance with, for example, a cost related to a basic power fee, a power usage fee, a charging facility introduction cost, a charging facility maintenance cost, and the like.

  In the present embodiment, the user may use a plurality of EVs 500. Also in this case, for each EV 500, the amount of charging power charged by the user using the target charging facility is calculated, and billing information is generated according to the amount of charging power of each EV 500. Here, the charging information may be notified to the user for each EV 500, or the charging information of a plurality of EVs 500 may be notified collectively. In addition, when a user uses a plurality of EVs 500, it is not limited to the case where a plurality of EVs 500 are charged by the same charging facility, and a plurality of EVs 500 may be charged by different charging facilities. To do.

Each functional unit described above is realized by cooperation of software and hardware resources. Specifically, for example, when the charge management server 200 is realized with the hardware configuration shown in FIG. 2, a program stored in the ROM 202 or the HDD 204 is read into the RAM 203 and executed by the CPU 201. Functional units such as the target user extraction unit 211, the target user information acquisition unit 212, the charging power amount calculation unit 213, the charging information generation unit 214, and the charging information output unit 215 illustrated in FIG. 3 are realized.
In the present embodiment, the target user information acquisition unit 212 is used as an example of an acquisition unit. As an example of the charging degree specifying unit, a charging power amount calculation unit 213 and a charging information generation unit 214 are used. As an example of output means, a billing information generation unit 214 and a billing information output unit 215 are used.

<Price calculation processing procedure>
Next, a procedure of processing in which the charge management server 200 and the charge management server 300 calculate the charge for the user is described. FIG. 5 is a flowchart showing an example of a processing procedure for calculating the charge of the user. In this example, it is assumed that each process is executed once a month.
In the following description, the process step may be referred to as the symbol “S”.

  First, the target user extraction unit 211 of the charge management server 200 accesses the EV management server 100 and extracts a target user (S101). Here, the target user extraction unit 211 identifies a target charging facility that is a target of charge calculation. And the target user extraction part 211 extracts all the use users defined beforehand as what uses a target charging equipment as a target user.

  Next, the target user information acquisition unit 212 accesses the EV management server 100 and acquires the information of the target user's EV 500 extracted in S101 (S102). In this example, the target user information acquisition unit 212 acquires position information of the target user's EV 500 and information related to charging of the target user's EV 500 as information for one month.

  Next, for each target user extracted in S101, the charging power amount calculation unit 213, based on the position information of the EV 500 acquired in S102, the time zone in which the EV 500 was at the target charging facility (that is, chargeable) Time zone) is specified (S103). Next, for each target user extracted in S101, the charging power amount calculation unit 213 charges the EV 500 charged in the EV 500 in the chargeable time zone based on the information related to the charging of the EV 500 acquired in S102. Is calculated (S104).

  Next, the charging information generation unit 214 generates charging information for each target user based on the charging power amount of each target user calculated in S104 (S105). For example, the billing information generation unit 214 calculates the charge power amount ratio of each target user in the target charging facility as the billing information. Next, the billing information output unit 215 outputs billing information of each target user to the charge management server 300 that manages the target charging facility (S106).

  Next, the fee management server 300 calculates a fee to be charged for each target user based on the received billing information (S107). Next, the fee management server 300 outputs information on the fee charged to the target user to the user terminal 400 of each target user (S108). Then, this processing flow ends.

  In addition, you may perform the process of S101-S108 at a different time. For example, when charging is performed on a monthly basis, the processing of S105 to S108 may be performed on a monthly basis, while the processing of S101 to S104 may be performed on a weekly basis.

<Specific example of charge calculation processing>
Next, the process in which the charge management server 200 and the charge management server 300 calculate the charge for the user is explained with a specific example. In this example, it is assumed that processing from extraction of a user to billing is performed on a monthly basis.

  First, the target user extraction unit 211 of the charge management server 200 identifies a target charging facility that is a target of charge calculation. For example, the target charging facility is specified from the list of charging facilities. In this example, the charging facility installed in the apartment A is specified as the target charging facility.

Next, the target user extraction unit 211 accesses the EV management server 100 and extracts all the users who use the charging facility of the apartment A from the users who use the EV 500 as target users. In this example, user A, user B, and user C living in the apartment A are extracted as target users.
In other words, the user who uses the charging facility of the apartment A has been registered in advance. The target user extraction unit 211 extracts all the users who use the charging facility of the apartment A based on prior registration.

  Next, the target user information acquisition unit 212 accesses the EV management server 100 and acquires information on the EV 500 for the users A to C. In this example, the target user information acquisition unit 212 acquires position information of each target user's EV 500 and information related to charging of the target user's EV 500 for one month to be charged.

Next, the charging power amount calculation unit 213 identifies the time period (that is, the chargeable time period) in which the EV 500 was at the charging facility of the apartment A based on the position information of the EV 500 for the users A to C. . In this example, the chargeable time zone is specified based on the position information of the EV 500 for one month to be charged.
Next, the charge power amount calculation unit 213 calculates the charge power amount charged in the EV 500 in the chargeable time zone for the users A to C based on information related to the charge of the EV 500.

  FIG. 6 is a diagram for explaining a specific example of the process of calculating the charging power amount. In the illustrated example, the position information and the remaining amount of charge power are shown for the EV 500 of the user A. In the illustrated graph, the vertical axis represents the remaining amount (%) of the charging power amount of EV 500, and the horizontal axis represents the date and time. And about the EV500 of the user A, the remaining amount of charge electric energy in the period from December 2, 2018 to December 6, 2018 is shown.

Here, based on the positional information of the EV 500 of the user A, the chargeable time zone when the EV 500 was at the charging facility of the apartment A is specified. Further, the amount of charging power charged in EV 500 in the chargeable time zone is calculated.
More specifically, EV 500 is in condominium A at 12:00 on December 2, 2018, and the remaining amount of charge power is increasing at that timing. Therefore, the amount of charging power is calculated assuming that this charging is performed by the charging facility of the apartment A. In this example, since the remaining amount of charging power is increased from 40% to 100%, this increased amount becomes the charged charging power. For example, when the battery capacity of the rechargeable battery 501 of EV500 is 10 kWh, it is calculated as 6 kWh.

Similarly, the EV 500 is in the condominium A at 9:00 on December 4, 2018, and the remaining amount of charge power is increasing at that timing. Therefore, the amount of charging power is calculated assuming that this charging is also performed by the charging facility of the apartment A. In this example, since the remaining amount of charging power is increased from 0% to 40%, this increased amount becomes the charged charging power. For example, when the battery capacity of the rechargeable battery 501 of the EV 500 is 10 kWh, it is calculated as 4 kWh.
As a result, the amount of charging electric power charged by the user A's EV 500 with the charging facility of the apartment A is calculated as a total of 10 kWh in the period from December 2, 2018 to December 6, 2018.

  In this way, the charging power amounts of the users A to C are calculated. In this example, it is assumed that the charging power amounts of the users A to C are calculated as 100 kWh, 200 kWh, and 300 kWh, respectively, in one month to be charged.

  Next, the billing information generation unit 214 generates billing information for the target user according to the charging power amount of each target user. In this example, the billing information generation unit 214 calculates a charge power amount ratio of each target user as billing information. Since the charging power amounts of the users A to C are 100 kWh, 200 kWh, and 300 kWh, respectively, the ratio of the charging power amounts of the users A to C is 1: 2: 3. Therefore, the charging information generation unit 214 generates information indicating that the ratio of the charging power amounts of the users A to C is 1: 2: 3 as the charging information. Then, the billing information output unit 215 outputs the billing information of the users A to C to the fee management server 300 that manages the charging facility of the apartment A (for example, the fee management server 300 of the management association of the apartment A). .

  Next, the charge management server 300 calculates a charge for charging the users A to C based on the received charging information. In this example, the charge management server 300 apportions the EV charging service fee by 1: 2: 3 because the ratio of the charging power amounts of the users A to C is 1: 2: 3. For example, when the EV charging service charge is 60,000 yen, the charge charged to the user A is 10,000 yen, the charge charged to the user B is 20,000 yen, and the charge charged to the user C is 30,000 yen. . Then, the fee management server 300 outputs fee information to the user terminals 400 of the users A to C.

In addition, when calculating a charge based on the ratio of the charge power amount, it is not necessary to distribute in proportion to the ratio of the charge power amount. For example, you may add a coefficient with respect to the ratio of charging electric energy. For example, when the coefficient is added as the charging power amount increases, if the ratio of the charging power amounts of the users A to C is 1: 2: 3, the EV charging service fee is 1: 2.1: 3.2. You can make a good decision.
In addition, a basic charge is set, the basic charge is charged to users A to C, and the EV charge service charge minus the basic charge for three persons is prorated as 1: 2: 3. The prorated charge may be charged to user A to user C.

  Further, in the example shown in FIG. 6, an increase in the remaining amount of charge power is observed at 15:00 on December 5, 2018. According to the position information of the EV 500 at this time, the EV 500 is in the charging station A. Therefore, the amount of charging power is calculated on the assumption that this charging is performed by the charging facility of the charging station A. In this example, since the remaining amount of charging power is increased from 0% to 100%, this increased amount becomes the charged charging power. For example, when the battery capacity of the rechargeable battery 501 of the EV 500 is 10 kWh, it is calculated as 10 kWh. The charging for the charging is performed separately from the charging for the charging facility of the apartment A.

To explain further, in a charging facility provided in a public place such as the charging station A, unlike a charging facility provided in a non-public place such as the condominium A, a user who uses the charging facility in advance It may not be registered. In such a case, the user is charged according to the amount of charging power. For example, if it is 100 yen per kWh, 1000 yen is charged at 10 kWh.
However, the charging facility provided in a public place such as the charging station A can also be charged in proportion to the user by registering the user in advance.
Furthermore, when charging with a charging facility provided in a non-public place such as the condominium A, charging may be performed according to the amount of charging power, instead of charging the user appropriately.

  Thus, in this Embodiment, it is not limited to the structure with which EV500 and charging equipment (namely, charging place) are tied by 1 to 1, for example, charging equipment of condominium A, charging stand A, etc. A configuration in which a single EV 500 is charged by a plurality of charging facilities is also included, as in the case of the charging facility. As described above, the plurality of charging facilities here include a charging facility provided in a non-public place (for example, a charging facility for an apartment A) and a charging facility provided in a public place (for example, a charging stand). A charging facility A), a configuration using a plurality of charging facilities provided in a non-public place, and a configuration using a plurality of charging facilities provided in a public place are also included.

  More specifically, when the EV 500 is charged by a plurality of charging facilities, the user may be notified of charging information for each charging facility, or the charging performed by each charging facility. The user may be collectively notified of the billing information. More specifically, for example, a company that provides an EV charging service or a management company that manages charging facilities manages a plurality of charging facilities, and a user who uses each charging facility is registered in advance. Here, for example, the billing information generation unit 214 generates billing information for each user for each charging facility, so that a plurality of registered users are registered with a plurality of charging facilities. Billing information for charging performed at the charging facility is collectively notified.

<Another example of the amount of charging power to be charged>
In the example described above, the charge power amount calculation unit 213 calculates the charge power amount charged in the EV 500 in the chargeable time zone. Then, the billing information generation unit 214 generates billing information for billing the target user according to the calculated charging power amount. However, in the present embodiment, the index to be charged is not limited to the amount of charging power.

  For example, the charging power amount calculation unit 213 may calculate the number of times the EV 500 has been charged in the target charging facility based on information related to charging of the target user's EV 500. In this case, the charging information generation unit 214 generates charging information for charging each target user based on the number of times of charging of all target users who use the target charging facility. In addition, although the charge frequency may be acquired directly from the EV management server 100, a value indirectly calculated based on other information may be used. For example, if the amount of charging power increases when the EV 500 is at the location of the target charging facility based on the position information of the EV 500, the number of times of charging is added once as if charging has been performed.

  In addition, for example, the charging power amount calculation unit 213 may calculate the charging time during which the EV 500 is charged in the chargeable time zone based on information related to charging of the target user's EV 500. In this case, the charging information generation unit 214 generates charging information for charging each target user based on the charging time of all target users who use the target charging facility. The charging time may be acquired directly from the EV management server 100, but a value indirectly calculated based on other information may be used. For example, in the chargeable time zone, the time when the remaining amount of charge power of EV 500 is increased is set as the charge time.

Further, for example, the charging information generation unit 214 may consider information related to the model of the EV 500 in addition to the charging time in generating charging information. For example, since the performance and battery capacity of the rechargeable battery 501 differ depending on the model of the EV 500, the amount of charge power that can be charged per unit time may differ. Therefore, the billing information generation unit 214 generates billing information for billing each target user based on the charging time of all target users who use the target charging facility and the model of the EV 500.
More specifically, for example, it is assumed that for two EVs 500A and EV500B, the vehicle types are vehicle type A and vehicle type B, respectively, and the ratio of the charge power amount that can be charged per unit time is 1: 2. Here, for the EV 500A and EV 500B, when the charging time calculated by the charging power amount calculation unit 213 is the same, the charging power amount charged in the EV 500 is 1: 2. Therefore, the charging information generation unit 214 sets the charging rate of the target user of the vehicle type B (ie, EV 500B) to twice the charging rate of the target user of the vehicle type A (ie, EV 500A).

In addition, a special fee may be set according to the vehicle type for the purpose of intensively selling a specific vehicle type. In this case, the billing information generation unit 214 generates billing information for billing each target user in consideration of a special fee according to the vehicle type.
More specifically, for example, it is assumed that for two EVs 500A and 500B, the respective vehicle types are vehicle type A and vehicle type B, and the special fee corresponding to the vehicle type is set to 1: 2. Here, when the charging time calculated by the charging power amount calculation unit 213 is the same for the EV 500A and the EV 500B, the charging information generation unit 214 determines the charging rate of the target user of the vehicle type B (ie, EV 500B) as the vehicle type A. (Ie EV500A) is set to double the charge rate of the target user.

For example, the charging information generation unit 214 may consider the remaining amount of charge power of the rechargeable battery 501 at the start of charging, in addition to the charging time, in generating charging information. For example, the amount of charge power that can be charged per unit time may vary depending on the remaining amount of charge power of the rechargeable battery 501 at the start of charging. Therefore, the billing information generation unit 214 applies to each target user based on the charging time and the remaining amount of charge power of the rechargeable battery 501 at the start of charging for all target users using the target charging facility. Billing information for charging is generated.
More specifically, for example, regarding the two EVs 500A and EV500B, the remaining amount of charge power of the rechargeable battery 501 at the start of charging is 90% for EV500A and 10% for EV500B. Further, it is assumed that the remaining amount of charge power of the rechargeable battery 501 at the start of charging is 90% and 10%, and the ratio of charge power that can be charged per unit time is 1: 2. Here, for the EV 500A and EV 500B, when the charging time calculated by the charging power amount calculation unit 213 is the same, the charging power amount charged in the EV 500 is 1: 2. Therefore, the charging information generation unit 214 sets the charging rate of the target user of the EV 500B to twice the charging rate of the target user of the EV 500A.

Further, for example, the charging information generation unit 214 may consider the deterioration status of the rechargeable battery 501 in addition to the charging time in generating charging information. For example, depending on the deterioration state of the rechargeable battery 501, the amount of charge power that can be charged per unit time may vary. Therefore, the charging information generation unit 214 generates charging information for charging each target user based on the charging time of all target users who use the target charging facility and the deterioration status of the rechargeable battery 501.
The deterioration status of the rechargeable battery 501 includes, for example, a travel history of the EV 500 (for example, travel distance, number of accelerations, number of decelerations), years of use of the rechargeable battery 501, past number of recharges in the rechargeable battery 501, and past number of discharges. From information such as.

  Furthermore, in the present embodiment, it is also possible to combine the above-described billing target indicators. That is, in the present embodiment, indicators such as the amount of charging power, the number of times of charging, the charging time, the vehicle type, the battery capacity of the rechargeable battery 501, the remaining amount of charging power at the start of charging, the deterioration status of the rechargeable battery 501, etc. The billing information may be generated in any combination. For example, the charging information generation unit 214 may generate the charging information in consideration of the remaining charge power amount of the rechargeable battery 501 at the start of charging, in addition to the information related to the charging time and the EV 500 vehicle type.

  In this embodiment, based on the number of times of charging, the charging time, the degree calculated based on the charging time and information on the vehicle type, the charging time and the remaining amount of charge power of the rechargeable battery 501 at the start of charging. The calculated degree is used as an example of the degree of charging.

<Other examples of charge calculation processing>
Next, another example of processing in which the charge management server 200 and the charge management server 300 calculate the charge for the user is described. Other examples include a process for increasing the accuracy of charge calculation and a process for preventing fraud.

(Process to increase the accuracy of charge calculation)
A first process for increasing the accuracy of fee calculation will be described.
In the present embodiment, the amount of charging power charged in EV 500 is measured by an electric meter provided in the charging facility, and the amount of charging power calculated from information acquired from EV management server 100 based on the measured value. May be corrected. The electric meter is a meter capable of measuring at least one of electric power (unit: kW) and electric energy (unit: kWh).

In this case, the target charging facility is provided with an electric meter for measuring the amount of charging power charged in the EV 500. Then, when charging the EV 500 with the target charging facility, the amount of charging power is measured by an electric meter. And the measured value of an electric meter is output to the charge management server 200 via networks, such as the internet. The charge power amount calculation unit 213 of the charge management server 200 calculates a total value of the charge power amount charged in the target charging facility during the target period (for example, for one month) based on the received measurement value of the electric meter. calculate.
Further, based on the information acquired from the EV management server 100, the charging power amount calculation unit 213 calculates the total value of the charging power amount charged to the EV 500 by each target user during the target period. Then, the charging power amount calculation unit 213 compares the total value of the charging power amount, which is a measured value, with the total value of the charging power amount calculated from the information of the EV management server 100. When there is a difference between the two, the value of the charging power amount calculated from the information of the EV management server 100 is corrected.

  For example, it is assumed that the total value of the charging power amount which is a measured value is 100 kWh and the total value of the charging power amount calculated from the information of the EV management server 100 is 110 kWh. In this case, the charge is calculated by uniformly multiplying the charging power amount of each user using the information calculated from the information of the EV management server 100 by 1 / 1.1. For example, when the total amount of charging power is changed from 110 kWh to 100 kWh, the electricity charge for the charging facility is reduced, and the charge charged to each user is also reduced.

  In addition, if a comparison is made between the total value of the charging power amount as a measured value and the total value of the charging power amount calculated from the information of the EV management server 100, it is possible to grasp the tendency of the difference between the two. It is. Therefore, in the subsequent fee calculation, correction may be made without comparing the two. Moreover, after comparing the both several times and further grasping the tendency of the difference between the two, it may be corrected without comparing both in the subsequent fee calculation.

  Further, in this example, the measured value of the charging electric energy is used to correct the value of the charging electric energy calculated from the information of the EV management server 100, but other measured values are used for correction. Also good. For example, the charging time may be measured with an electric meter, and the measured value may be used to correct the charging time value calculated from the information of the EV management server 100.

Next, a second process for increasing the accuracy of charge calculation will be described.
In the present embodiment, for example, even when EV500 cannot enter the position information of EV500 by GPS because EV500 has entered the room, charging is performed at the target charging facility depending on the remaining amount of charge power at the surrounding time. The charged amount of charging power may be calculated.

For example, when the target charging facility is indoors, position information indicating that the EV 500 is at the location of the target charging facility may not be acquired when the EV 500 enters the indoor. In this case, the charging power amount calculation unit 213 calculates the charging power amount of the target charging facility with reference to position information in the vicinity of the target charging facility.
More specifically, for example, the charging power amount calculation unit 213 is based on the position information of the EV 500 when the EV 500 enters the location of the target charging facility (for example, within the premises of the building where the target charging facility is installed). The remaining amount of charge power at the time of entry) and the remaining amount of charge energy at the time EV500 leaves the location of the target charging facility (for example, when it exits the site of the building where the target charging facility is installed). The difference is calculated. This difference is specified as the amount of charging power charged by the target charging facility.
In addition, for example, the difference between the remaining amount of charge power when EV500 position information is no longer acquired and the remaining amount of charge power when position information acquisition is resumed around the target charging facility is calculated. The charging power amount charged by the target charging facility may be specified.

(Process to prevent fraud)
A first process for preventing fraud will be described.
In the present embodiment, a warning may be output when a user who is not predetermined to use the target charging facility charges the target charging facility.

The target user information acquisition unit 212 is not limited to the information on the EV 500 of the user who is predetermined as the target charging facility to be used, but also information on the EV 500 of other users (that is, EV 500 position information, EV 500 charging). Information). Here, the information of EV500 may be acquired focusing on the user who is suspected of being charged at the target charging facility. The user who is suspected of being charged at the target charging facility is, for example, a user who was at the location of the target charging facility or a user who entered the site of the building where the target charging facility was installed, based on the position information of EV500. . If there is a user who has a history of charging the EV 500 with the target charging facility other than the user who is predetermined as the target charging facility, the target user information acquisition unit 212 manages the target charging facility. A warning is output to the charge management server 300.
In addition, the presence or absence of the history of charging at the target charging facility is, for example, charging when the EV 500 leaves the site rather than the remaining amount of charge power when the EV 500 enters the site of the building where the target charging facility is installed. This is determined based on whether or not the remaining amount of power is increasing.

  When the charge management server 300 detects a warning, for example, the manager of the target charging facility rushes to the location of the target charging facility. When the frequency with which the target user information acquisition unit 212 acquires information is in units of several minutes to several hours, an administrator may run under the EV 500 while charging the EV 500 performing fraud. In this way, it is prevented that a user who is not determined in advance to use the target charging facility is charged by the target charging facility.

Next, the second process for preventing fraud will be described.
In the present embodiment, a difference between the total value of the charging power amount measured by the electric meter and the total value of the charging power amount of each target user calculated based on the information acquired from the EV management server 100 is determined in advance. A warning may be output when the threshold is exceeded.

In this case, the target charging facility is provided with an electric meter for measuring the amount of charging power charged in the EV 500. Then, when charging the EV 500 with the target charging facility, the amount of charging power is measured by an electric meter. And the measured value of an electric meter is output to the charge management server 200 via networks, such as the internet. The charge power amount calculation unit 213 of the charge management server 200 calculates a total value of the charge power amount charged in the target charging facility during the target period (for example, for one month) based on the received measurement value of the electric meter. calculate.
Further, based on the information acquired from the EV management server 100, the charging power amount calculation unit 213 calculates the total value of the charging power amount charged to the EV 500 by each target user during the target period. Here, the charge power amount calculation unit 213 targets the EV 500 of the user who is predetermined as the one that uses the target charging facility. Then, the charging power amount calculation unit 213 compares the total value of the charging power amount, which is a measured value, with the total value of the charging power amount calculated from the information of the EV management server 100.

  When the difference between the two exceeds a predetermined threshold, a user who is predetermined as a user who uses the target charging facility is used by another user (that is, a user who is not predetermined as a user who uses the target charging facility). It is conceivable that a user) is called in and charged by the target charging facility, or a user who is not determined in advance as using the target charging facility arbitrarily charges. Therefore, when the difference between the two exceeds a predetermined threshold, the target user information acquisition unit 212 outputs a warning to the charge management server 300 that manages the target charging facility. In this way, it is prevented that a user who is not determined in advance to use the target charging facility is charged by the target charging facility.

<Other examples>
In the above-described example, when the target user extraction unit 211 extracts the target user, the target charging facility is specified, and the user who uses the specified target charging facility is extracted as the target user. However, the method of extracting the target user is not limited to this.
For example, the target user extraction unit 211 may access the EV management server 100 without specifying the target charging facility, and extract any user as a target user from all the users. In this case, the target user extraction unit 211 acquires the extracted location information of the target user's EV 500 and information related to charging of the EV 500 from the EV management server 100. Then, for example, the time zone in which the charging is performed is specified by a change in the remaining amount of charging power of the EV 500. Further, the charging facility that has been charged is specified based on the position information of the specified time zone. The charging information of the charging facility is generated by calculating the charging power amount of all the users using this charging facility.
For example, when the EV 500 of a certain target user is charged at the apartment A and the charging station A, the charging for the charging at the apartment A also considers charging of other users in the charging facility of the apartment A. In addition, charging for charging at the charging station A is performed according to the amount of charging power, for example.

  In the above-described example, the target user extraction unit 211 extracts the target user that is the target of the charge calculation, but does not extract the target user, and the EV 500 that is the target of the charge calculation (hereinafter referred to as “target vehicle”). May be extracted. In this case, EV 500 information that is predetermined to use the target charging facility is stored in the EV management server 100, the charge management server 200, the charge management server 300, or the like. Then, the target user information acquisition unit 212 accesses the EV management server 100 and extracts all the EVs 500 that are determined in advance as using the target charging facility as target vehicles. In the same manner as in the above-described example, the charging information for charging the target vehicle is specified for the extracted target vehicle (that is, the user who uses the target vehicle is charged). Billing information) is generated. Further, the target user information acquisition unit 212 may extract any EV 500 as the target vehicle from all the EVs 500 without specifying the target charging facility. In this case as well, billing information is generated by specifying the time zone during which the extracted target vehicle was charged, the charging facility, the amount of charged power, and the like.

  Furthermore, in the above-described example, the EV 500 is charged by the charging facility. However, in the charging facility in which a charger / discharger capable of charging and discharging is installed, the EV 500 can also discharge. In this case, the target user information acquisition unit 212 may acquire information related to discharging of the EV 500 from the EV management server 100 in addition to information related to charging of the EV 500. Then, similarly to the charging power amount of EV 500, charging power amount calculation unit 213 may calculate the discharging power amount (that is, the degree of discharge) of EV 500 performed in the charging facility.

When calculating the discharge power amount, billing information is generated based on the charge power amount and the discharge power amount.
For example, billing information is generated based on the actual charge power amount obtained by subtracting the discharge power amount from the charge power amount of the target user.
In the charge calculation, the charge may be calculated based on the actual charge power amount obtained by subtracting the discharge power amount from the charge power amount, and the consideration for the discharge is paid to the target user according to the discharge power amount. May be. Moreover, while calculating a charge based on charge electric energy, you may pay the object user with respect to discharge separately from the charge. More specifically, for example, if the peak of power consumption of the entire building is suppressed (that is, peak cut), the electricity bill of the entire building is reduced. Therefore, the compensation for the discharge is paid based on the degree of contribution to the peak cut of the power consumption of the entire building by the discharge.

In the present embodiment, part of the function of the charge management server 200 is realized by another device (for example, the charge management server 300), or part of the function of the charge management server 300 is performed by another device (for example, charge management). Or the server 200).
For example, in the example described above, the charging information generation unit 214 of the charging management server 200 generates charging information, but the charging management server 300 may generate charging information based on information from the charging management server 200. Further, for example, the charge management server 300 does not calculate the charge charged to the target user, but calculates the charge charged by the charge management server 200 to the target user, and the charge information to the user terminal 400 of the target user. May be output.

  Further, the program for realizing the embodiment of the present invention can be provided not only by communication means but also by storing it in a recording medium such as a CD-ROM.

Although various embodiments and modifications have been described above, it is of course possible to combine these embodiments and modifications.
Further, the present disclosure is not limited to the above-described embodiment, and can be implemented in various forms without departing from the gist of the present disclosure.
