[1. Charging system configuration]
FIG. 1 is a diagram showing a configuration of a charging system 100 according to an embodiment of the present invention. The charging system 100 is a system for charging a storage battery mounted as a power source in a vehicle such as an electric vehicle. In the following description, the charging system 100 charges the storage battery 132 mounted on the vehicle 130 used by the user by the charging stand 114 installed in the charging station 110. The vehicle 130 corresponds to an example of an electric vehicle.

The charging station 110 is a place where one or a plurality of charging stands 114 for charging the vehicle 130 are installed. The charging station 110 may be provided by partitioning a part of the parking lot, or the charging station 110 may be an independent facility.

In this embodiment, the charging station 110 is associated with a commercial business operator. A commercial transaction business operator is a business operator that operates a business such as product sales or service provision, and is, for example, a commercial business operator, a non-profit business operator, a public business operator, or the like. The commerce business operator referred to here may be an electronic commerce business operator that engages in businesses such as online product sales and service provision.

The association between the charging station 110 and the commercial transaction business operator is not bound by the actual installation location or capital relationship, but it is preferable that the charging station 110 is close to the commercial facility operated by the commercial transaction business operator. Specifically, it is preferable that the positional relationship is such that the user of the vehicle 130 can visit the commercial facility while the vehicle 130 is being charged at the charging station 110. As a typical example, a mode in which a charging station 110 is installed in a parking lot of a commercial facility such as a store or a shopping mall operated by a commercial transaction business can be mentioned. Further, the charging station 110 may be installed in a place independent of the commercial facility. For example, it is possible to provide a charging station 110 in a parking lot set up by a business operator other than the commercial transaction business operator, and associate the charging station 110 with the commercial transaction business operator. In this case, it is preferable that the charging station 110 is close to the commercial facility.
In this embodiment, as an example, an example in which a charging station 110 is installed in a parking lot of a commercial facility operated by a commercial transaction business operator will be described.

The charging system 100 uses communication by the communication network 107. The communication network 107 connects various devices so as to be able to communicate with each other. The specific embodiment of the communication network 107 is not limited, and includes, for example, a communication network such as a dedicated line, a public line, or the Internet. Further, the communication network 107 may be a wide area network including a plurality of communication networks. Further, the communication network 107 may include various devices such as a circuit switching device and a server. Further, the communication network 107 may include a wireless communication line.

The charging system 100 accepts input from a user who uses the vehicle 130.
The vehicle 130 is a mobile body that is temporarily or continuously managed or used by the user, may be a vehicle owned by the user, or may be provided to the user by car sharing, rental car, car leasing, or the like. .. The specific mode of the vehicle 130 is not limited, and any vehicle may be used as long as it uses the storage battery 132 as a power source. The vehicle 130 is, for example, a four-wheeled vehicle, a motorcycle, another light vehicle, or the like, and in the present embodiment, the vehicle 130 will be described as a four-wheeled vehicle equipped with a storage battery 132. Further, the user who receives the service provided by the charging system 100 does not have to be the driver of the vehicle 130.

There is no limit to the number of users who use the charging system 100 or the number of vehicles 130 that the users drive. FIG. 1 illustrates two vehicles 130a and 130b as an example of a vehicle 130 used by a user. The vehicles 130a and 130b are provided with storage batteries 132a and 132b as power sources, respectively. The vehicles 130a and 130b are vehicles used by different users.

In the following description, when the vehicles 130a and 130b are generically referred to, or when any one of them is referred to, the vehicle 130 is referred to. Similarly, when the storage batteries 132a and 132b are collectively referred to, or when any one of them is referred to, the storage battery 132 is referred to. Further, the same notation method is adopted for the charging stands 114a and 114b, the sensors 116a and 116b, and the stop positions 118a and 118b, which will be described later.

The charging system 100 includes a condition management server 103. The condition management server 103 manages information about the commercial transaction business operator associated with the charging station 110. The condition management server 103 is communicably connected to the charge management device 112 via the communication network 107.

The charging stand 114 is a device for charging an in-vehicle storage battery. A charging management device 112 that is communicably connected to the charging stand 114 is installed in the charging station 110. In the present embodiment, as an example, the configuration in which the charging stand 114 and the charging management device 112 are connected by wire is shown, but the charging management device 112 and the charging stand 114 may be connected by wireless communication. The charging stand 114 corresponds to an example of the charging device of the present invention.

There is no limit to the number of charging stands 114 installed in the charging station 110. The charging stand 114 installed in the charging station 110 is managed by the charging management device 112. A configuration in which one charge management device 112 is installed in one charging station 110 is typical, but for example, a configuration in which a plurality of charge management devices 112 for managing a plurality of charging stands 114 are installed in the charging station 110. Of course, it is also possible.

FIG. 1 shows, as an example, a configuration in which two charging stands 114a and 114b are installed. The charging stands 114a and 114b are installed in accordance with the stop positions 118a and 118b where the vehicle 130 stops during charging. The charging stands 114a and 114b are provided with sensors 116a and 116b for detecting that the vehicle 130 has stopped at the stop positions 118a and 118b, respectively.

The sensors 116a and 116b can be composed of, for example, a proximity sensor, a radar sensor, a camera, or the like, and may be a weight sensor embedded in the stop position 118a. The sensors 116a and 116b are not limited to the configuration in which the sensors 116a and 116b are individually installed in the vicinity of the charging stands 114a and 114b. For example, the charging station 110 is provided with a camera that includes both the stop positions 118a and 118b in the image pickup range, and the vehicle 130 is stopped at each of the stop positions 118a and 118b based on the images captured by this camera. May be configured to be able to detect. In this case, one camera functions as the sensor 116a and the sensor 116b.

The charging stands 114a and 114b have charging cables 119a and 119b connected to the vehicle 130, and supply power via the charging cables 119a and 119b.
When the charging stands 114a and 114b detect the vehicle 130 by the sensors 116a and 116b and detect that the charging cables 119a and 119b are connected to the vehicle 130, the charging stands 114a and 114b supply electric power for charging to the vehicle 130 and supply the storage battery 132 to the storage battery 132. Perform charging.
The charging stands 114a and 114b may be configured to supply electric power for charging the storage battery 132 to the vehicle 130 in a non-contact manner without using the charging cables 119a and 119b.

When a user who uses the vehicle 130 wants to charge the storage battery 132, he / she can charge the storage battery 132 by moving the vehicle 130 to the charging station 110 and connecting the vehicle 130 to the charging stand 114.

The charging stand 114 is capable of communicating with the vehicle 130. For example, the charging station 114a communicates with the vehicle 130 stopped at the stop position 118a. The specific mode of communication is arbitrary, for example, the charging cable 119a is composed of a cable having a power feeding function and a communication function, and the charging stand 114a executes communication with the vehicle 130 via the charging cable 119a. It may be a configuration. Further, the charging stand 114a and the vehicle 130 may be configured to be capable of performing wireless communication. The charging stand 114b can also communicate with the vehicle 130 by the same configuration as the charging stand 114a.

The charging stations 114a and 114b may acquire vehicle identification information from the vehicle 130 by communicating with the vehicle 130. Further, the charging stands 114a and 114b may transmit the vehicle identification information acquired from the vehicle 130 to the charging management device 112.
Further, the function of the charging stands 114a and 114b to communicate with the vehicle 130 may be used as an alternative to the sensors 116a and 116b. That is, the charging stands 114a and 114b may detect the vehicle 130 capable of executing communication as a vehicle 130 stopped at the stop positions 118a and 118b. In this case, the charging stands 114a and 114b can omit the hardware for detecting the vehicle 130.

The charge management device 112 manages the charge to the storage battery 132 executed by the charging stand 114. For example, the charge management device 112 detects the progress of charging the storage battery 132 by communicating with the charging stands 114a and 114b. Further, for example, the charge management device 112 transmits control information to the charging stands 114a and 114b to adjust the electric power supplied to the vehicle 130 by the charging stands 114a and 114b.

The charging stand 114 includes a touch panel 115. The touch panel 115 displays various screens including characters and images to notify the user of various information. Further, the touch panel 115 detects a touch operation by the user. Therefore, the user can operate the touch panel 115 to input a desired charge amount and the like.

[2. Overview of charging system operation]
FIG. 2 is a diagram showing the correlation between the charging time of the vehicle 130 at the charging station 110 and the user satisfaction. In the chart shown in FIG. 2, the charging time is on the horizontal axis, and the correlation D indicates that the user satisfaction differs depending on the length of the charging time. The upper side of the correlation D indicates the user satisfaction. Further, the lower side of the correlation D shows a commercial opportunity of a commercial transaction business operator associated with the charging station 110, and is, for example, a sales opportunity of a commercial facility.

If the charging station 110 is installed in the vicinity of the commercial facility, the user may stay in the commercial facility while charging the vehicle 130. Normally, the user of the vehicle 130 expects that the state where the remaining amount of the storage battery 132 is low is quickly resolved, so that it can be said that the shorter the charging time, the higher the user's satisfaction. On the other hand, in a commercial facility close to the charging station 110, if the charging time is long, the user's staying time is long, so that the effect of increasing the number of customers staying in the commercial facility can be expected. Here, the customer may include a potential customer. Therefore, for the commercial transaction business operator, the longer the charging time of the vehicle 130 is, the more the commercial opportunity is enhanced. That is, as shown as correlation D in FIG. 2, the shorter the charging time, the higher the user satisfaction and the less commercial opportunity. Conversely, the longer the charge time, the lower the user satisfaction and the more commercial opportunities.

The charging system 100 creates a plurality of charging plan candidates and presents them to the user in order to realize management that appropriately reflects user satisfaction and commercial opportunities. The charging plan includes a charging time for charging the vehicle 130 by the charging stand 114, and corresponds to an example of usage conditions of the charging stand 114. Then, the user can select a desired charging plan from the plurality of charging plans presented by the charging system 100.
As an example of a plurality of charging plans, the first plan, the second plan, and the third plan are illustrated in FIG. The charging time is different between the first plan, the second plan, and the third plan.

Since the charging time of the first plan is shorter than that of the second plan and the third plan, the user satisfaction U1 of the first plan is higher than the user satisfaction U2 of the second plan and the user satisfaction U3 of the third plan. Correspondingly, the commercial opportunity M1 of the first plan is smaller than the commercial opportunity M2 of the second plan and the commercial opportunity M3 of the third plan.

The plurality of charging plans created by the charging system 100 are accompanied by incentives corresponding to the difference in charging time. Specifically, a plan with a long charge time has an incentive for a long charge time. The incentive is provided, for example, by a commercial operator associated with the charging station 110.

For example, since the second plan has a longer charging time than the first plan, a discount on the charging fee is included as an incentive for this difference in charging time. Although the user satisfaction U2 is smaller than the user satisfaction U1 when evaluated only by the charging time, the overall user satisfaction is enhanced by giving an incentive. That is, the second plan may be more beneficial to the user than the first plan. The third plan has a longer charging time than the second plan, so it has a more profitable incentive. For commerce operators, adding incentives may provide greater commercial opportunities as users may choose a longer charging plan.

As described above, the charging system 100 realizes the management of the charging stand 114, which appropriately distributes the profits of both the commercial transaction business operator associated with the charging station 110 and the user who charges at the charging station 110.

In the following description, a case where a user using the vehicle 130a charges the storage battery 132a by the charging stand 114a will be described as an example.
In the present embodiment, the user who uses the vehicle 130a operates the charging stand 114a and inputs a desired charging amount or the like. The content input by the user is transmitted to the charging management device 112 that manages the charging stand 114a as the requirement information 121. The requirement information 121 includes, in a typical example, a charge amount for charging the storage battery 132a. Further, the requirement information 121 may include information specifying whether the storage battery 132a is normally charged by the charging stand 114a or is rapidly charged in a relatively shorter time than the normal charging. Further, the requirement information 121 may include information indicating a charging charge specified by the user and information indicating a charging time specified by the user.

Upon receiving the requirement information 121, the charge management device 112 requests the condition management server 103 for information regarding the commercial transaction business operator associated with the charging station 110. The charge management device 112 acquires the application condition 123 from the condition management server 103. Applicable condition 123 is information provided by a commercial transaction business operator in order to appropriately set an incentive.

FIG. 3 is a diagram showing a configuration example of the application condition 123. The application condition 123 shown in FIG. 3 includes sales information 123a, congestion rate information 123b, and condition designation information 123c. The sales information 123a is information regarding sales of a commercial facility close to the charging station 110. The sales information 123a may be information indicating the sales amount at the time when the condition management server 103 generates the application condition 123 or the achievement rate of the sales amount with respect to the target value.
The congestion rate information 123b is information indicating the congestion rate of the commercial facility, and is the number of customers staying in the commercial facility, the number of customers per sales floor area, and the like. The condition designation information 123c is a condition set by the commercial transaction business operator regarding the provision of incentives in addition to the sales information 123a and the congestion rate information 123b. The application condition 123 may include at least one of the sales information 123a and the congestion rate information 123b.

Returning to FIG. 1, the charge management device 112 creates a plurality of charge plans by combining the charge time and the incentive based on the application condition 123, and creates a candidate plan 125 including the plurality of charge plans. The candidate plan 125 is transmitted from the charge management device 112 to the charging stand 114a, and the charging stand 114a displays the candidate plan 125 on the touch panel 115a.

FIG. 4 is a diagram showing a configuration example of the candidate plan 125.
The candidate plan 125 includes a plurality of charging plans presented to the user as candidates. The example of the charging plan included in the candidate plan 125 is not limited, and FIG. 4 shows an example of the candidate plan 125 including the three charging plans 125a, 125b, and 125c.

The charging plans 125a, 125b, 125c all include information about the numbers, charge amounts, charging times, and basic incentives attached to the plans. The basic incentive is an incentive provided for a difference in charging time for each charging plan, and specifically, an incentive for increasing the charging time.

The charging plans 125a, 125b, 125c may be configured to include additional conditions and additional incentives. The additional incentive is an incentive provided for matters other than the length of charge time, and the additional condition is a condition for providing the additional incentive.

For example, the additional condition is to purchase goods or services from a commercial business operator associated with the charging station 110. In this case, more detailed conditions may be included regarding the purchase price, the product or service to be purchased, the purchase quantity, the purchase time, and the like. Purchases of goods and services may be limited to real stores or may include online transactions. Further, a plurality of stores may be targeted, and in this case, detailed conditions may be set for each store.
In addition to cash, the additional incentive may be an increase in the amount of charge at the charging station 110, a discount on the charge charge, or the like. Examples of the method of providing the additional incentive include issuance of a coupon ticket, issuance and presentation of a character code or an image code that functions as a coupon.

Further, if the charging system 100 including the charging stand 114 can identify the individual user or the vehicle 130a, it may provide points having economic value as an additional incentive.

For example, vehicle identification information may be added to the vehicle 130 as information that can uniquely identify the individual vehicle 130. The vehicle identification information includes a vehicle identification number (VIN: Vehicle Identification Number), a registration number given by the government, and the like.
In this case, as a basic incentive or an additional incentive, the charge amount may be increased, the charge charge may be discounted, points may be given, or other incentives may be provided in association with the vehicle identification information of the vehicle 130a.

Further, in the charging system 100, customer identification information may be given to the user as information that can uniquely identify the user. The customer identification information may be a membership number given to a member who uses the charging system 100. Further, the customer identification information may be a social security number or taxpayer number given by the government, information given to the user by a system other than the charging system 100, or other personal information. May be. Further, information that can uniquely identify a terminal device such as a smartphone used by the user may be used as customer identification information. Specifically, the telephone number or serial number of the smartphone may be used as customer identification information. In this case, a basic incentive or an additional incentive may be provided in association with the customer identification information of the user.

FIG. 5 is a diagram showing an example of the candidate plan display screen 300. The candidate plan display screen 300 is displayed on the touch panel 115 and is a screen for displaying a list of candidates for a plurality of charging plans based on the candidate plan 125.
The candidate plan display screen 300 includes a selection guidance message 301 that guides the user to select one of the charging plans.

In the example of FIG. 5, three charging plan candidates are displayed on the candidate plan display screen 300. The candidate plan display screen 300 includes a plan display unit 311, 312, 313.
The plan display unit 311 shows the contents of the first charging plan, and here, it is a plan to charge the charge amount specified in the requirement information 121 with a standard charging time.

The plan display unit 312 shows the contents of the second charging plan, which has a longer charging time than the charging plan of the plan display unit 311. The plan display unit 312 includes incentive information 312a explaining the basic incentive provided in response to the long charging time. In addition, the plan display unit 312 includes the provision of the additional incentive and the additional incentive information 312b explaining the conditions under which the additional incentive is provided.

The plan display unit 313 shows the contents of the third charging plan, which has a longer charging time than the charging plan of the plan display unit 312. The plan display unit 313 includes incentive information 313a explaining the basic incentive provided in response to the long charging time. In addition, the plan display unit 313 includes the provision of the additional incentive and the additional incentive information 313b explaining the conditions under which the additional incentive is provided.

The plan display units 311 and 312, 313 function as touch-operable buttons on the touch panel 115a. Therefore, when the user touches any of the plan display units 311, 312, and 313, the charging plan corresponding to the touch-operated plan display unit is selected.

When the user performs an operation of selecting a charging plan, the charging stand 114a charges the storage battery 132a according to the charging plan selected by the user. After charging is complete, the incentive is actually provided, for example, when the user pays the charging fee.

The plurality of charging plans displayed on the candidate plan display screen 300 are not limited to the example of FIG. For example, a charge plan with a basic incentive may be displayed on the plan display unit 311 as a first charge plan. Further, the operation of the charge management device 112 is not limited to the example in which the second and third charge plans are created with the first charge plan as a reference. Specifically, the standard charging plan is not limited to the plan for charging the charge amount of the requirement information 121 with the standard charging time, for example, the charging time is longer than the standard charging time and the basic incentive. The charging plan with the above may be used as a reference. In this case, a charging plan having less basic incentive and a shorter charging time than the standard charging plan may be created and displayed on the candidate plan display screen 300. Further, it is not essential that the standard charging plan is the first charging plan, and the standard charging plan may be displayed on the candidate plan display screen 300 as the second and third charging plans.

[3. Charging stand configuration]

It is provided with a candidate plan notification unit 234 to be used.

Further, the charge management method executed by the charge management device 112 includes a step of acquiring requirement information 121 regarding the use of the charge stand 114 for the vehicle 130 charged by the charge stand 114, and a proposed condition 127 for the use of the charge stand 114. The acquisition includes a step of creating a candidate for a charging plan of the charging stand 114 by combining the requirement information 121 and the proposed condition 127, and a step of notifying the candidate of the charging plan. Each of these steps corresponds to steps S201, S205, S207, and S209 shown in FIG.

Further, the function of the charge management device 112 is realized as a control program 241 which is a program that can be executed by a computer. The control program 241 is a program that can be executed by a computer, and is a requirement acquisition unit 231 for acquiring requirement information 121 regarding the use of the charging stand 114 for the vehicle 130 charged by the charging stand 114, and a charging stand. The proposal condition creation unit 232 for acquiring the proposal condition 127 for the use of 114, the candidate plan creation unit 233 for creating a charging plan candidate for the charging stand 114 by combining the requirement information 121 and the proposal condition 127, and the charging plan It is a program characterized by functioning as a candidate plan notification unit 234 for notifying candidates.

According to the configuration of the charging management device 112, it is possible to realize the management of the charging stand 114 that reflects the interests of both the user who charges the vehicle 130 using the charging stand 114 and the business operator who installs the charging stand 114. Since the charge plan candidate created by the charge management device 112 is created based on, for example, the requirement information 121 that reflects the user's designation and the proposed condition 127, the merits of both the user and the business operator are reflected. Can be a candidate.

Further, the proposal condition creation unit 232 acquires the proposal condition 127 after the requirement acquisition unit 231 acquires the requirement information 121. Therefore, it is possible to create a candidate charge plan by using the proposed condition 127 regarding the index that changes with time. For example, by installing a charging station 114 and using the proposal condition 127 related to the business condition of the commercial transaction business operator to be used, the situation of the commercial transaction business operator can be adjusted according to the situation of the commercial transaction business operator. Can be reflected in the creation of the candidate plan 125.

Further, the requirement information 121 is information for designating at least one of a charging amount and a charging time for charging the vehicle 130 from the charging stand 114. Thereby, for example, the candidate plan 125 can be created and notified based on the charge amount and the charge time desired by the user.

Further, the proposed condition 127 includes information indicating a change in the charging amount and / or the charging time specified by the requirement information 121, and the candidate plan creation unit 233 proposes the charging amount and / or the charging time of the requirement information 121. Create a plurality of charging plans including a charging plan changed according to the above and a charging plan not changing the requirement information 121. Thereby, for example, when the requirement information 121 that reflects the user's wishes is used, it is possible to create a charging plan that reflects the merits of both the user and the business operator.

Further, the candidate plan creation unit 233 creates a plurality of charging plans having different charging times. This makes it possible to create a candidate plan 125 including a charging plan that reflects the merits of both the user and the operator with respect to the length of time for charging the vehicle 130.

In addition, the candidate plan creation unit 233 creates a charging plan that has a longer charging time than other charging plans and includes the provision of incentives. Therefore, by providing an incentive, the user can be motivated to choose a charging plan with a long charging time. Therefore, it is possible to appeal to the user a usage pattern in which the business operator who uses the charging stand 114 has a great profit.

Further, the proposal condition creation unit 232 is any one of the sales amount of the commercial transaction business operator associated with the charging station 114, the conditions preset by the commercial transaction business operator, and the congestion status of the facility associated with the charging station 114. Based on 1 or more, the proposed condition 127 is determined. In this case, the appealing power of the charging plan can be adjusted according to the business condition of the commercial transaction business operator, and for example, the effect of attracting customers can be changed.

Further, a plurality of commercial business operators may be associated with the charging station 110 and / or the charging stand 114. In this case, the candidate plan notification unit 234 may create a charging plan having a basic incentive or an additional incentive related to a plurality of commercial business operators. For example, additional conditions and incentives for purchasing goods and services in stores, online transactions, and commercial facilities in which a plurality of commercial business operators are involved may be added to the charging plan. As an example, when the user selects this charging plan, the user may be provided with a charge amount or a discount coupon when the product is purchased at, for example, one of a plurality of stores.

When a plurality of commercial business operators are involved in the additional incentives and conditions of the charging plan, it is conceivable that the resources for providing the additional incentives to the users are proportionally distributed and borne by the plurality of commercial business operators. For example, regarding the purchase act of a user who meets the additional conditions, the source of funds for each commercial transaction business is based on the payment amount of the user at the store or the like in which each commercial transaction business is involved and the usage time when the user uses each store or the like. You may decide the amount to be borne. If multiple commerce operators are involved in the basic incentive, it can be handled in the same way.

Further, the charge management device 112 includes a charge stand control unit 235 that causes the charge stand 114 to execute charging according to the charge plan 129 selected from the charge plan candidates notified by the candidate plan notification unit 234.
