Description of the First Embodiment
FIG. 1 is an explanatory view showing a schematic configuration of a charging system according to a first embodiment of the present invention. As shown in FIG. 1, the charging system 101 includes a charging device 11 provided at a plurality of (three in the drawing) charging spots (sometimes referred to as "charging stations" or "charging stations"). The charging device 11 charges the battery of the electric vehicle 13 by connecting a charging cable to the electric vehicle 13. In addition, a data center 12 (server) connected to each charging device 11 via a network is provided. Then, data communication between the data center 12 and each charging device 11 is enabled.

  Further, data communication is enabled between the data center 12 and each of the electric vehicles 13 having a communication function. Specifically, data communication is enabled between the data center 12 and communication devices mounted on the respective electric vehicles 13 or portable terminals (such as mobile phones and smart phones) possessed by the occupants of the electric vehicles 13. There is.

  FIG. 2 is a block diagram showing the detailed configuration of the charging device 11 and the data center 12 shown in FIG. In FIG. 2, one charging device 11 and one electric vehicle 13 are shown. As shown in FIG. 2, the charging device 11 converts power (for example, 100 V, 50 Hz) supplied from a commercial power source into DC power and outputs power for battery charging. , ID recognition unit 22 (vehicle recognition unit), charge amount detection unit 23, and display unit 24 are provided.

  The ID recognition unit 22 and the charge amount detection unit 23 may be provided in the data center 12, or the accumulated charge amount calculation unit 32 may be provided in the charging device 11. Further, the communication unit 21, the ID recognition unit 22, and the charge amount detection unit 23 can be configured as an integrated computer including storage means such as a central processing unit (CPU), RAM, ROM, hard disk, etc. .

  The communication unit 21 communicates with the data center 12. When the electric vehicle 13 to be charged is stopped in the parking space of the charging device 11 and the charging cable is connected between the charging device 11 and the electric vehicle 13, the ID recognition unit 22 Communication is performed between them to recognize the ID (identification information) of the electric vehicle 13.

  The charge amount detection unit 23 detects a charge electric energy (hereinafter, abbreviated as “charge amount”) charged by the charging device 11 of the electric vehicle 13 having a charge request. The display unit 24 displays various types of information to be provided to the occupant of the electric vehicle 13, and displays, for example, incentive information (details will be described later) provided to the occupant.

  The data center 12 includes a communication unit 31 (communication unit) that communicates with each charging device 11 and each electric vehicle 13, a cumulative charge amount calculation unit 32, an incentive setting unit 33, and a storage unit 34. Have. The “incentive” described in the present invention is, for example, a charge rate discount rate, gift certificate, multipurpose usage coupon, multipurpose usage point, charger priority usage ticket, etc., and the monetary value enjoyed by the vehicle occupants It is a concept that includes values other than money or money.

  When the electric vehicle 13 is charged by any one of the charging devices 11, the accumulated charge amount calculation unit 32 obtains the charge amount at this time, and calculates the accumulated charge amount. The calculation result is stored in the storage unit 34 for each of the electric vehicles 13. For example, for a certain electric vehicle (indicated by 13A), when the amount of power of 5000 [KWh; kilowatt hour] has been charged in the past and the amount of power of 30 [KWh] has been charged by this charge, this is accumulated The accumulated charge amount is set to 5030 [KWh], and this data is overwritten and stored in a predetermined area of the storage unit 34.

  The incentive setting unit 33 sets an incentive for each of the electrically powered vehicles 13 based on the accumulated charge amount of each of the electrically powered vehicles 13 stored in the storage unit 34. In the present embodiment, a discount rate of the charge rate is used as an example of the incentive. Hereinafter, the method of setting the incentive will be described with reference to the correspondence table shown in FIG. The correspondence table shown in FIG. 3 is stored in the storage unit 34. Then, the charge rate discount rate is set to be higher as the accumulated charge amount [KWh] is larger.

  Specifically, when the accumulated charge amount is 0 to 3500 [KWh], the discount rate is “1”, so the charge per unit amount of power at the time of charge is set to the prescribed charge “A” set in advance. It is set. In other words, do not discount. When the accumulated charge amount is 3501 to 7000 [KWh], the discount rate is "0.9", so the charge rate is set to the charge obtained by multiplying the defined charge "A" by 0.9. . In other words, it is discounted by 10%. Hereinafter, similarly, the discount rate increases as the accumulated charge amount increases.

  Since the accumulated charge amount is stored in the storage unit 34, it does not decrease. Therefore, the discount rate once reached is set as permanent. The present invention is not limited to this, and it is also possible to reset the accumulated charge amount by dividing the time limit by a fixed period (for example, one year). For example, when one of the charging devices 11 is not used for one year, it is also possible to adopt a method of resetting the accumulated charge amount of the electric vehicle.

  The storage unit 34 is used to store various data. In particular, the accumulated charge amount and data of the discount rate according to the accumulated charge amount are stored for each of the registered electric vehicles 13. Also, the correspondence table shown in FIG. 3 is stored.

  Next, the operation of the charging system 101 according to the present embodiment configured as described above will be described with reference to the flowchart shown in FIG. First, in step q11, the data center 12 determines whether a transmission request signal of incentive information has been received from any of the electric vehicles 13. When the request signal is received, in step q12, the data center 12 transmits the incentive information to the electric vehicle 13 or a portable terminal carried by the occupant of the electric vehicle 13.

  The incentive information is information on the discount rate of the charge rate set based on the accumulated charge amount of the electrically powered vehicle 13. In this process, for example, when the electric vehicle 13 inputs an ID and transmits a request signal, information on the accumulated charge amount corresponding to the ID is read from the storage unit 34, and information on the discount rate according to the information ( 3) is transmitted from the data center 12 to the electric vehicle 13. The occupant of the electric vehicle 13 can recognize the discount rate by looking at this information. In addition, regardless of the presence or absence of the transmission request from the electric vehicle 13, the incentive information may be transmitted at predetermined time intervals set in advance.

  In step p11, the charging apparatus 11 confirms that a certain electric vehicle 13A (electric vehicle to be charged) stops in the parking space, and the charging cable is connected to the electric vehicle 13A.

  In step p12, the charging device 11 recognizes the ID (identification information) of the connected electric vehicle 13A, and transmits this ID to the data center 12 via the network.

  In step q13, the data center 12 recognizes that the electrically powered vehicle 13A is to be charged based on the transmitted ID. Thereafter, in step q14, the accumulated charge amount of the electrically powered vehicle 13A is read out from the storage unit 34. That is, as described above, since the accumulated charge amount of each of the electric vehicles 13 is stored in the storage unit 34 shown in FIG. 2, the accumulated charge amount stored for the electric vehicle 13A is read.

  In step q15, the incentive setting unit 33 sets an incentive for the electrically powered vehicle 13A based on the accumulated charge amount of the electrically powered vehicle 13A. Specifically, with reference to the correspondence table shown in FIG. 3, a discount rate (for example, 0.9 or the like) by which the prescribed charge "A" is multiplied is set. And the information regarding this incentive is transmitted to the charging device 11 via a network.

  In step p13, the charging device 11 receives the information on the incentive and displays it on the display unit 24. Specifically, the discount rate of the charging fee (for example, 0.9 etc.) is displayed. The occupant of electric powered vehicle 13A can recognize the current discount rate by viewing this display. Furthermore, by looking at this display, it can be determined whether to charge or to stop charging.

  In step p14, the charging device 11 determines whether a charging operation has been performed. When the charging operation is performed (YES in step p14), charging is started in step p15.

  After that, when the charging is finished, the charging device 11 detects the charging amount in the current charging in step p16, and transmits this data to the data center 12 via the network.

  At step q16, the data center 12 reads the transmitted charge amount. Furthermore, in step q17, the read charge amount is added to the accumulated charge amount up to the previous time, and in step q18, it is stored in the storage unit 34 as a new accumulated charge amount. By doing this, the latest accumulated charge amount of the electric vehicle 13A is overwritten and stored in the storage unit 34.

  The data rewrite situation by the above process will be described with reference to the application table shown in FIG. For the electrically powered vehicle 13A, the accumulated charge amount before charging is 5500 [KWh]. Therefore, based on the correspondence table shown in FIG. 3, the discount rate is 0.9. And, when the charge amount of this time is 20 [KWh] and the charge "A" per unit electric energy is 50 yen, the discount rate is 0.9, so the charge rate of this time is , 50 * 20 * 0.9 = 900, it will be 900 yen. Further, the accumulated charge amount after charging is updated to 5520 [KWh] by performing the current charging, and is overwritten and stored in the storage unit 34.

  Thus, the occupant of the electrically powered vehicle 13A can receive an incentive because the accumulated charge amount of the electrically powered vehicle 13A reaches 3501 [KWh] (see FIG. 3), and the electrically powered vehicle 13A can be provided at a cheaper price than usual. It will be possible to charge.

  Thus, in the charging system 101 according to the present embodiment, the storage unit 34 stores the accumulated charge amount which is the accumulation of the amount of electric power charged to the respective electric powered vehicles 13 in the past. Then, when the electric vehicle 13A to be charged is charged by the charging device 11, the accumulated charge amount of the electric vehicle 13A is read, and the discount rate (incentive) of the charge fee is set according to the accumulated charge amount. . At this time, the discount rate is set to be higher as the accumulated charge amount is larger. Therefore, it is possible to give the occupants of the electric vehicle 13 a desire to further increase the accumulated charge amount, and it is possible to increase the usage frequency of the charging device 11 provided in a commercial facility or the like.

  Further, since the discount rate information is displayed on the display unit 24 of the charging device 11, the current discount rate can be recognized for the occupant of the electric vehicle 13, and it is easy to determine whether or not to charge. be able to.

  Furthermore, as long as the electrically powered vehicle 13 is a charging device 11 connected to the data center 12 via a network, the accumulated charging amount can be accumulated regardless of which charging device 11 charges, and the incentive can be enhanced. Because the charging location is not limited, it is versatile. Further, since information on incentives is transmitted to the electric vehicles 13 by communication when a request signal from the electric vehicles 13 is received or at predetermined time intervals, the occupants of the electric vehicles 13 are notified of the information of the incentives. it can.

First Modification of First Embodiment
Next, a first modified example of the first embodiment will be described. In the first embodiment described above, an example has been described in which the discount rate of the charging fee is used as the incentive given to the occupants of the vehicle. In other words, as the accumulated charge amount increases, an example is given in which the monetary value added is given to the occupant by discounting the charge required for charging.

  On the other hand, in the first modified example, a "multipurpose coupon" is used as an incentive to be given to the occupant. That is, the multipurpose usage coupon is distributed according to the accumulated charge amount. The multipurpose coupon is, for example, a car wash at a charging spot, a check, a discount ticket for discounting the charge of car products, a discount ticket for a product at a coffee shop or fast food store, a discount ticket for a product at a convenience store, etc. .

  Then, as shown in the correspondence table in FIG. 6, when the accumulated charge amount is less than 7000 [KWh], one multipurpose use coupon is distributed each time charging is performed. When the accumulated charge amount is 7001 to 15000 [KWh], two multipurpose coupons are distributed each time charging is performed. At this time, the coupon is distributed on the condition that the charging fee is 500 yen or more.

  For example, as shown in the application table of FIG. 7, for the electric vehicle 13A, the accumulated charge amount before charging is 8000 [KWh], the current charge quantity is 15 [KWh], and per unit electric energy When the charge "A" is 50 yen, the current charge is 50 * 15 = 750, 750 yen. Since this amount of money exceeds 500 yen, which is the condition for distributing coupons, the number of coupons to be distributed to the occupants is two as shown in FIG. Further, by performing the current charging, the accumulated charge amount after charging is updated to 8015 [KWh], and is overwritten and stored in the storage unit 34.

  Thus, in the charging system according to the first modification, when the electric vehicle 13A to be charged is charged by the charging device 11, it is distributed to the occupant according to the accumulated charge amount of the electric vehicle 13A. Set the number of multipurpose coupons (incentives). At this time, the number of multipurpose coupons is set to increase as the accumulated charge amount increases. Therefore, it is possible to give the occupants of the electric vehicle 13A a desire to further increase the accumulated charge amount, and it is possible to increase the usage frequency of the charging device 11 provided in a commercial facility or the like.

Second Modification of First Embodiment
Next, a second modification of the first embodiment will be described. In the second modification, a "charger priority ticket" is used as an incentive to be given to a passenger. As shown in the schematic diagram of FIG. 8, the charger priority use ticket is provided with the priority lane L1 capable of being charged in a shorter waiting time, and this charger priority use ticket is used by using the charger priority use ticket at the time of congestion. It is permitted to line up in the priority lane L1. That is, it becomes possible to charge in short waiting time by using a charger priority use ticket.

  Then, as shown in the correspondence table of FIG. 9, when the accumulated charge amount is less than 7000 [KWh], one charger priority use ticket is distributed each time charging is performed. Further, when the accumulated charge amount is in the range of 7001 to 15000 [KWh], two charger priority use tickets are distributed each time charging is performed. Under the present circumstances, a charger priority use ticket is distributed on condition that a charge rate is 500 yen or more.

  For example, as shown in the application table of FIG. 10, for the electric vehicle 13A to be charged, the accumulated charge amount before charge is 5000 [KWh], the current charge amount is 15 [KWh], and the unit If the charge "A" for the amount of power is 50 yen, the current charge will be 750 yen at 50 * 15 = 750. Since this amount of money exceeds 500 yen, which is the distribution condition of the charger priority ticket, the number of the charger priority ticket to be distributed to the occupant is one based on the correspondence table of FIG. Further, by performing the current charging, the accumulated charge amount after charging is updated to 5015 [KWh], and is overwritten and stored in the storage unit 34.

  Thus, in the charging system according to the second modification, when the electric vehicle 13A to be charged is charged by the charging device 11, it is distributed to the occupant according to the accumulated charge amount of the electric vehicle 13A. Set the number of charger priority tickets (incentives). Under the present circumstances, it is set so that the number of sheets of a charger priority use ticket may increase, so that accumulated charge amount is large. Therefore, it is possible to give the occupants of the electric vehicle 13 a desire to further increase the accumulated charge amount, and it is possible to increase the usage frequency of the charging device 11 provided in a commercial facility or the like.

Third Modification of First Embodiment
Next, a third modification of the first embodiment will be described. In the third modified example, a "multipurpose use point" is used as an incentive given to the occupant. The multipurpose use point is a point that can be used as a cash voucher. And 1 point is provided for every charge fee 100 yen. Also, as the accumulated charge amount increases, the points to be provided increase.

  FIG. 11 is a correspondence table showing the relationship between the accumulated charge amount and the number of points given at the time of charge. As shown in FIG. 11, when the accumulated charge amount is less than 7000 [KWh], a point "C" of 1/100 (rounded down) of the charge rate is given. When the accumulated charge amount is 7001 to 15000 [KWh], the coefficient by which the point "C" is multiplied is "1.5". In other words, points are multiplied by 1.5. Furthermore, when the accumulated charge amount exceeds 15000 [KWh], the coefficient is set to "2" and the point is doubled.

  For example, as shown in the application table of FIG. 12, for the electric vehicle 13A, the accumulated charge amount before charging is 25000 [KWh], the current charge amount is 15 [KWh], and per unit electric energy If the charge is 50 yen, the charge for this time will be 750 yen at 50 * 15 = 750. Therefore, since the above point "C" is "7" and the accumulated charge amount exceeds 15001 [KWh], the coefficient by which the point "C" is multiplied is "2" based on the correspondence table of FIG. It becomes. Therefore, “14” is added to the multipurpose use point “200” before charging, and the multipurpose use point after charging is “214”.

  Further, by performing the current charging, the accumulated charge amount after charging is updated to 25015 [KWh], and the multipurpose use point is updated to "214", and is overwritten and stored in the storage unit 34.

  Thus, in the charging system according to the third modification, when the electric vehicle 13A to be charged is charged by the charging device 11, a multipurpose use point (incentive) according to the charging fee is provided. Furthermore, as the accumulated charge amount increases, the multipurpose use point to be provided increases. Therefore, it is possible to give the occupants of the electric vehicle 13 a desire to further increase the accumulated charge amount, and it is possible to increase the usage frequency of the charging device 11 provided in a commercial facility or the like.

Description of Second Embodiment
Next, a second embodiment of the present invention will be described. In the second embodiment, one week is distinguished by a time zone, and according to the degree of congestion in each time zone in the charging device 11, the level of the incentive is set. The details will be described below.

  The overall configuration of the charging system 102 according to the second embodiment is the same as that shown in FIG. FIG. 13 is a block diagram showing the configuration of the charging system 102 according to the second embodiment, and includes a charging device 11 and a data center 12a. In addition, in FIG. 13, only one charging device 11 is shown. Then, as in the first embodiment described above, the charging device 11 and the data center 12a can communicate via the network, and the data center 12a and the electric vehicle 13 can also communicate similarly by the network or the like. It is done.

  The second embodiment is different from the data center 12 shown in FIG. 2 in that the data center 12 a includes a correction operation unit 35. The other configuration is the same as that of FIG. 2, so the same reference numerals are given and the description of the configuration is omitted.

  When the electric vehicle 13 is charged by the charging device 11, the correction operation unit 35 performs a process of correcting the charge amount to be added to the accumulated charge amount according to the degree of congestion at that time. Specifically, a proportional constant is set according to the degree of congestion, and the proportional constant is multiplied by the charge amount to correct the charge amount. Then, the charge amount after correction is added to the accumulated charge amount. Specifically, as shown in FIG. 14, one week from Monday to Sunday is divided into three time zones of "0 to 8 o'clock", "8 to 18 o'clock", and "18 to 24 o'clock", respectively. . That is, one week is divided into 21 time zones. And the congestion degree for every time slot is calculated | required about each charge apparatus 11 from the charge performance in the past (for example, charge performance for the latest one week). That is, the correction operation unit 35 has a function as a time zone setting unit that sets a time zone in which the operation rate of each charging device 11 is high and a time zone in which the operation rate is low.

  And, for example, 18-24 o'clock on Monday and Wednesday is set to a time zone in which the operating rate of the charging device 11 is the lowest (hereinafter referred to as "off time zone"), and 8-18 o'clock on Saturday and Sunday is a charging device 11 is set to the highest time slot (hereinafter referred to as "busy time slot"). The storage unit 34 stores information on the off-peak time zone and the busy-time zone for each charging device 11. The off-hours and busy hours are updated regularly (for example, one week, one month, etc.). Then, as described later, the incentive is set to be high when charging in the off hours, and, conversely, the incentive is set to be low when charging in the busy hours.

  Next, the processing procedure of the charging system 102 according to the second embodiment will be described with reference to the flowchart shown in FIG. First, in step q31, the data center 12a determines whether a transmission request signal of incentive information has been received from any of the electric vehicles 13. When the request signal is received, in step q32, the information on the incentive is notified to the electric vehicle 13 as the request source. Specifically, the information on the off-peak time zone and the busy time zone is transmitted to the electric vehicle 13 or a portable terminal carried by the occupant of the electric vehicle 13.

  For example, as shown in FIG. 16, the charging device 11 of “Kanagawa first station” has a busy time zone of Saturday and Sunday in the week from 0 o'clock on January 1 to 0 o'clock on January 8 The data center 12a notifies the electrically powered vehicle 13 of information indicating that it is 8 to 18 o'clock and the non-consecutive time zone is 18 to 24 o'clock on Monday and Wednesday. In addition, regardless of the presence or absence of the transmission request from the electric vehicle 13, the incentive information may be transmitted at predetermined time intervals set in advance. The occupant of the electric vehicle 13 can recognize the off hours and the busy hours by looking at this information.

  Next, in step p31, the charging device 11 confirms that the electric vehicle 13A to be charged is stopped in the parking space, and the charging cable is connected to the electric vehicle 13A.

  In step p32, the charging device 11 recognizes the ID (identification information) of the connected electric vehicle 13A, and transmits this ID to the data center 12a via the network.

  In step q33, the data center 12a recognizes that the electrically powered vehicle 13A is to be charged based on the transmitted ID. Thereafter, in step q34, the accumulated charge amount of the electrically powered vehicle 13A is read out from the storage unit 34. That is, as described above, since the accumulated charge amount for each of the electric vehicles 13 is stored in the storage unit 34 shown in FIG. 13, the accumulated charge amount stored for the electric vehicle 13A is read.

  In step q35, the incentive setting unit 33 sets an incentive for the electrically powered vehicle 13A based on the accumulated charge amount of the electrically powered vehicle 13A. Specifically, as shown in FIG. 3 described above, a discount rate (e.g., 0.9 or the like) by which the prescribed charge "A" is multiplied is set. Then, in the case of the busy time zone or the non-time zone, information on the incentive and information on the time zone are transmitted to the charging device 11 through the network.

  In step p33, the charging apparatus 11 receives the incentive information, and the information on the busy time zone and the low time zone, and displays the information on the display unit 24. The occupant of electric powered vehicle 13A can recognize the current discount rate by viewing this display. Furthermore, by looking at this display, it can be determined whether to charge or to stop charging.

  In step p34, the charging device 11 determines whether the charging operation has been performed. When the charging operation is performed (YES in step p34), charging is started in step p35.

  After that, when the charging is finished, the charging device 11 detects the charging amount in the current charging in step p36, and transmits this data to the data center 12a via the network.

  At step q36, the data center 12a reads the transmitted charge amount. Further, at step q37, the correction processing of the charge amount is executed. This process will be described in detail with reference to the flowchart of FIG.

  In step q38, the data center 12a adds the corrected charge amount to the cumulative charge amount up to the previous time, and stores it in the storage unit 34 as a new cumulative charge amount in step q39. As a result, the latest accumulated charge amount of the electric vehicle 13A is overwritten and stored in the storage unit 34.

  Next, the correction process of the charge amount shown at step q37 will be described with reference to the flowchart shown in FIG. First, in step S11, the correction operation unit 35 recognizes a time zone at the time of charge execution from the time zones shown in FIG.

  Next, in step S12, the correction operation unit 35 determines whether the time zone at the time of charge execution is a busy time zone. In the example shown in FIG. 14, the busy time zone is a time zone of 8 to 18 o'clock on Saturday and Sunday. If it is the busy time zone (YES in step S12), the process proceeds to step S14. In step S14, the correction operation unit 35 sets a correction coefficient α (α <1). Here, α is, for example, “0.5”.

  On the other hand, when it is not the busy time zone (NO in step S12), in step S13, correction operation unit 35 determines whether or not the time zone at the time of charge execution is the loose time zone. In the example shown in FIG. 14, the time zone of 18 to 24 o'clock on Monday and Wednesday is the off hours. If it is the non-concurrent time zone (YES in step S13), the process proceeds to step S15. In step S15, the correction operation unit 35 sets a correction coefficient β (β> 1). Here, β is, for example, “2”.

  In step S16, the correction operation unit 35 multiplies the amount of charge the electric vehicle 13A has charged this time by the correction coefficient α or β set in the process of step S14 or step S15. For example, when charging in the busy time zone, the charge amount is multiplied by the correction coefficient α, so that the charge amount is corrected to be smaller than the charge amount actually charged. For example, in the case where the charge amount is 20 [KWh] and α = 0.5, it is corrected to 10 [KWh]. On the other hand, in the case of charging in the non-consecutive time zone, the charge amount is multiplied by the correction coefficient β, so that the charge amount is corrected to be larger than the charge amount actually charged. For example, when the charge amount is 20 [KWh] and [beta] = 2, it is corrected to 40 [KWh].

  As described above, in the busy time zone where the use frequency of the charging device 11 is high, the charge amount charged this time is accumulated, for example, by 1/2, by setting the correction coefficient to a small numerical value α. Will be lower and you will not get many incentives.

  On the other hand, in the non-consecutive time zone where the frequency of use of the charging device 11 is low, setting the correction coefficient to a large numerical value β doubles and accumulates, for example, the charge amount charged this time. You can get It should be noted that the correction is not made in the case of a busy time zone and a time zone that does not belong to any of the non-busy time zones.

  Then, the charge amount calculated by the correction processing is added to the accumulated charge amount in step q38 of FIG. 15, and updated to a new accumulated charge amount.

  Thus, in the charging system 102 according to the second embodiment, the storage unit 34 stores the accumulated charge amount which is the total of the electric power amounts charged to the respective electric powered vehicles 13 in the past. Then, when the electric vehicle 13A to be charged is charged by the charging device 11, the accumulated charge amount of the electric vehicle 13A is read, and the discount rate (incentive) of the charge fee is set according to the accumulated charge amount. Do. At this time, the discount rate is set to be higher as the accumulated charge amount is larger. Therefore, it is possible to give the occupants of the electric vehicle 13 a desire to further increase the accumulated charge amount, and it is possible to increase the usage frequency of the charging device 11 provided in a commercial facility or the like.

  Further, when the electric vehicle 13 is charged by the charging device 11, the correction coefficient is set to be different depending on the non-consecutive time zone and the busy time zone set for the charging device 11. That is, when charging in the busy time zone, the charge amount smaller than the actual charge amount is added to the accumulated charge amount, and in the case of charging in the off time zone, the charge amount larger than the actual charge amount is cumulative It is added to the charge amount. Therefore, it is possible to give the occupants of the electric vehicle 13 a desire to charge in the off time zone while avoiding the busy time zone as much as possible, and it becomes possible to level out the congestion degree in each charging device 11 .

  In addition, when the request signal is given from the electric vehicle 13, the information on the off time zone and the busy time zone is transmitted. Therefore, the occupant of the electric vehicle 13 receives the information on the off time zone and the busy time zone. It becomes possible to select and charge the time zone which can be acquired easily and can obtain a higher incentive.

  In the second embodiment as well, as shown in the first to third modifications of the first embodiment, the incentive may be a "multipurpose coupon ticket", a "charger priority use ticket", a "multipurpose point", etc. It is possible.

  Further, in the flowchart shown in FIG. 15, when the driver of electric powered vehicle 13 gives a request signal in the process of step q31, data center 12a transmits information on the off time zone and the busy time zone. Although the present invention has been described, the present invention is not limited to this, and the data center 12a may be configured to periodically transmit information on off hours and busy hours.

  Furthermore, in the second embodiment described above, an example of setting the two time zones of the busy time zone and the non-consecutive time zone to determine the correction coefficients α and β has been described. It is also possible to correct the charge amount more finely by determining.

Description of Third Embodiment
Next, a third embodiment of the present invention will be described. In the first and second embodiments described above, the incentive is set based on the accumulated charge amount of each of the electric vehicles 13. On the other hand, in the third embodiment, an incentive is set based on the number of times the electric vehicle 13 is charged by the charging device 11. The details will be described below.

  The overall configuration of the charging system 103 according to the third embodiment is the same as that shown in FIG. FIG. 18 is a block diagram showing the configuration of the charging system 103 according to the third embodiment, and includes a charging device 11 b and a data center 12 b. Note that FIG. 18 shows one charging device 11 b and the electric vehicle 13. Then, as in the first and second embodiments described above, the charging device 11b and the data center 12b can communicate via the network, and the communication between the data center 12b and the electric vehicle 13 is similarly performed via the network etc. Is possible.

  In the third embodiment, the first embodiment shown in FIG. 2 is that the charging device 11b includes the number of times of charge detection unit 25 and the data center 12b includes the cumulative number of times of charge calculation unit 36. It is different from. The other configuration is the same as that of FIG. 2, so the same reference numerals are given and the description of the configuration is omitted.

  The number-of-charges detection unit 25 counts (counts) the number of times the electric vehicle 13 is charged by the charging device 11 b. However, as described later, when multiple charge operations are performed on the same date, the lower limit value is set for the charge amount, and only when the charge amount exceeds the lower limit value, the charge count is counted. (Count)

  The cumulative charge number calculation unit 36 obtains the charge number detected by the charge number detection unit 25, calculates the cumulative charge number for each electric vehicle, and stores the calculation result in the storage unit 34.

  FIG. 19 is a correspondence table showing the relationship between the number of times of charging and the discount rate of the charging fee stored in the incentive setting unit 33. As shown in FIG. 19, the discount rate is set to be high each time the accumulated number of times of charging increases 400 times. That is, assuming that the charge rate per unit power amount is “A”, the charge “A” is adopted as it is when the accumulated charge number is 1 to 400 times. In other words, do not discount. When the accumulated number of times of charging is 401 to 800 times, the discount rate is set to “0.9”, so the charging rate per unit power amount is “0.9 * A”. Furthermore, the discount rate increases as the accumulated charge number increases.

  Next, the operation of the charging system 103 according to the third embodiment will be described with reference to the flowchart shown in FIG. First, in step q51, the data center 12b determines whether a transmission request signal of incentive information has been received from any of the electric vehicles 13. When the request signal is received, the data center 12b transmits the incentive information to the electric vehicle 13 or a portable terminal owned by the occupant of the electric vehicle 13 in step q52.

  The incentive information is information on the discount rate of the charging fee set based on the accumulated number of times of charging of the electrically powered vehicle 13. In this process, for example, when the electric vehicle 13 inputs an ID and transmits a request signal, the information on the accumulated charge number corresponding to the ID is read from the storage unit 34, and the information on the discount rate according to the information is The data is transmitted from the data center 12 b to the electric vehicle 13. For example, when the accumulated number of times of charging is 500 times, as shown in FIG. 19, it is notified that the discount rate is “0.9”. In addition, regardless of the presence or absence of the transmission request from the electric vehicle 13, the incentive information may be transmitted at predetermined time intervals set in advance. The occupant of the electric vehicle 13 can recognize the discount rate by viewing this information.

  Next, in step p51, the charging device 11b confirms that the electric vehicle 13A to be charged is stopped in the parking space, and the charging cable is connected to the electric vehicle 13A.

  In step p52, the charging device 11b recognizes the ID (identification information) of the connected electric vehicle 13A, and transmits this ID to the data center 12b via the network.

  In step q53, the data center 12b recognizes that the electrically powered vehicle 13A is to be charged based on the transmitted ID. Thereafter, in step q54, the cumulative charge number of the electric vehicle 13A is read out from the storage unit 34. That is, as described above, since the accumulated charge number for each of the electric vehicles 13 is stored in the storage unit 34 shown in FIG. 18, the accumulated charge number stored for the electric vehicle 13A is read.

  In step q55, the incentive setting unit 33 sets an incentive for the electrically powered vehicle 13A based on the accumulated charge number of the electrically powered vehicle 13A. Specifically, as shown in FIG. 19 described above, a discount rate (for example, 0.9 or the like) to be multiplied by the prescribed charge "A" is set. And the information regarding this incentive is transmitted to the charging device 11b via a network.

  In step p53, the charging device 11b receives the information on the incentive and displays it on the display unit 24. The occupant of electric powered vehicle 13A can recognize the current discount rate by viewing this display. Furthermore, by looking at this display, it can be determined whether to charge or to stop charging.

  In step p54, the charging device 11b determines whether a charging operation has been performed. When the charging operation is performed (YES in step p54), charging is started in step p55.

  After that, when the charging is finished, the charging device 11b detects the charging amount in the current charging in step p56, and transmits this data to the data center 12b via the network.

  At step q56, the data center 12b reads the transmitted charge amount. Further, at step q57, the process of updating the number of times of charging is executed. This process will be described in detail with reference to the flowchart of FIG.

  In step q58, the data center 12b stores the accumulated number of times of charging in the storage unit 34. By doing this, the latest accumulated charging number of the electric vehicle 13A is overwritten and stored in the storage unit 34.

  Next, the charging frequency updating process shown in step q57 will be described with reference to the flowchart shown in FIG. First, in step S31, the cumulative charge number calculation unit 36 determines whether the current charge is the first charge today. Then, if it is the first time (YES in step S31), the cumulative charge number is incremented in step S33.

  If it is not the first time (NO in step S31), in step S32, accumulated charge number calculation unit 36 determines whether or not the current charge amount is equal to or greater than a preset threshold (for example, 15 [KWh]). . Then, if it is equal to or higher than the threshold (YES in step S32), the cumulative charge number is incremented in step S33. On the other hand, if the threshold has not been reached (NO in step S32), the cumulative charge number is not incremented in step S34. Thereafter, in the process of step q58 in FIG. 20, the accumulated number of times of charging stored in the storage unit 34 is updated.

  In the above process, when charging is performed a plurality of times a day, the accumulated charging number is incremented at least once. Then, after the second time, the accumulated charge number is incremented only when the threshold which is a certain amount of power is reached. By doing so, it is possible to prevent an act of increasing the cumulative number of times of charging by charging unintendedly.

  Next, the data rewrite situation by the above process will be described with reference to the application table shown in FIG. For the electrically powered vehicle 13A, the charge number on the day is the second, the accumulated charge amount before charge is 5500 [KWh], and the accumulated charge number is 1300. Therefore, according to the correspondence table shown in FIG. 19, the discount rate is 0.8. If the charge rate is 10 [KWh] and the charge per unit energy is 50 yen, the discount rate is 0.8, so the charge rate for this time is 50 * 10 * It will be 400 yen at 0.8 = 400. Further, the accumulated charge amount after charging is updated to 5510 [KWh] by performing the current charging, and is overwritten and stored in the storage unit 34.

  Further, since the charge number of the day is the second time and the threshold charge amount is set to 15 [KWh], the accumulated charge number is not incremented for the current charge. Therefore, the accumulated charge number after charge remains 1300 times.

  As described above, in the charging system 103 according to the third embodiment, the storage unit 34 stores the accumulated number of times of charging, which is the number of times of charging each electric vehicle 13 in the past. Then, when a certain electric vehicle 13A is charged by the charging device 11, the accumulated charge number of the electric vehicle 13A is read out, and a discount rate (incentive) of the charge fee is set according to the accumulated charge number. Under the present circumstances, it is set so that a discount rate may become high (incentive will become high), so that there are many accumulation frequency | counts of charge.

  Therefore, it is possible to give the occupants of the electric vehicle 13 a desire to further increase the accumulated charging frequency, and it is possible to increase the usage frequency of the charging device 11 provided in a commercial facility or the like.

  Further, since the discount rate information is displayed on the display unit 24 of the charging device 11, the current discount rate can be recognized by the driver of the electric vehicle 13, and it is easy to determine whether or not to charge. can do.

  Furthermore, since an incentive is given according to the number of times of charging, there is an advantage that the charging device 11 visits the charging device 11 in order to charge the electric vehicle which is not required to be charged because the charging capacity is not reduced so much. Operation rate can be effectively improved

  In addition, as long as the electric powered vehicle 13 is a charging device 11 connected to the data center 12 via a network, the accumulated charging frequency can be updated regardless of which charging device 11 charges, and thus the incentive can be enhanced. As it can, the charging place is not limited and it is versatile.

  Also in the third embodiment, as shown in the first to third modifications of the first embodiment described above, the incentive may be changed to a "multipurpose coupon ticket", "charger priority use ticket", "multipurpose point", etc. It is possible.

Description of the Fourth Embodiment
Next, a fourth embodiment of the present invention will be described. The overall configuration of the charging system 104 according to the fourth embodiment is the same as that shown in FIG. FIG. 23 is a block diagram showing the configuration of the charging system 104 according to the fourth embodiment, and includes a charging device 11 c and a data center 12 c. In FIG. 23, one charging device 11c and the electric vehicle 13 are shown. Then, as in the first to third embodiments described above, the charging device 11c and the data center 12c can communicate via the network, and the data center 12c and the electric vehicle 13 can similarly communicate via the network etc. Is possible.

  The fourth embodiment is different from the third embodiment shown in FIG. 18 in that the data center 12 c includes a correction operation unit 35. The other configuration is the same as that of FIG. 18, so the same reference numerals are given and the description of the configuration is omitted. Further, the correction calculation unit 35 is the same as the correction calculation unit 35 shown in FIG. In the fourth embodiment, an incentive is set using both the accumulated charge amount and the accumulated charge number. Details will be described below.

  In the fourth embodiment, the correspondence table as shown in FIG. 24 is stored in the storage unit 34. In the correspondence table shown in FIG. 24 (a), the discount rate of the power rate is set according to both the accumulated power amount and the accumulated charge number. At this time, as the accumulated power amount and the accumulated charge number increase, the discount rate increases. Specifically, as shown in a to f of FIG. 24, a discount rate is set. For example, when the accumulated charge amount is 8000 [KWh] and the accumulated charge number is 1000, the discount rate is set to 0.85 (see “c” in FIG. 24 (b)).

  Next, the operation of the charging system 104 according to the fourth embodiment will be described with reference to the flowchart shown in FIG. First, in step q71, the data center 12c determines whether a transmission request signal of incentive information is received from any of the electric vehicles 13.

  If the request signal is received, the data center 12c transmits the incentive information to the electric vehicle 13 or a portable terminal carried by the occupant of the electric vehicle 13 in step q72. The incentive information is information on the charge rate discount rate set based on the accumulated charge amount of the electric vehicle 13 and the accumulated charge frequency, and information on a busy time zone and a non-seasonal time zone described later.

  In this process, for example, when the electric vehicle 13 inputs an ID and transmits a request signal, information on the accumulated charge amount and the accumulated number of times of charge corresponding to the ID is read from the storage unit 34, and this information is Information on the discount rate (see FIG. 24) is transmitted from the data center 12c to the electric vehicle 13. Also, information on busy hours and off hours is transmitted. In addition, regardless of the presence or absence of the transmission request from the electric vehicle 13, the incentive information may be transmitted at predetermined time intervals set in advance. The occupant of the electric vehicle 13 can recognize the discount rate by looking at this information.

  Next, in step p71, the charging device 11c confirms that the electric vehicle 13A to be charged is stopped in the parking space, and the charging cable is connected to the electric vehicle 13A.

  In step p72, the charging device 11c recognizes the ID (identification information) of the connected electric powered vehicle 13A, and transmits this ID to the data center 12c via the network.

  In step q73, the data center 12c recognizes that the electrically powered vehicle 13A is to be charged based on the transmitted ID. Thereafter, in step q74, the accumulated charge amount of the electrically powered vehicle 13A and the accumulated number of times of charge are read out from the storage unit 34. That is, as described above, since the storage unit 34 shown in FIG. 23 stores the accumulated charge amount and the accumulated charge number for each of the electrically powered vehicles 13, the accumulated charge stored for the electrically powered vehicle 13A is stored. Read the amount and cumulative charge count.

  In step q75, the incentive setting unit 33 sets an incentive for the electrically powered vehicle 13A based on the accumulated charge amount of the electrically powered vehicle 13A and the accumulated number of times of charging. Specifically, with reference to the correspondence table shown in FIG. 24, a discount rate (for example, 0.9 or the like) by which the prescribed charge is multiplied is set. And the information regarding this incentive is transmitted to the charging device 11c via a network. Furthermore, it transmits information on busy time zones and off hours.

  In step p73, the charging apparatus 11c receives the incentive information, and the information on the busy time zone and the low time zone, and displays the information on the display unit 24. The occupant of electric powered vehicle 13A can recognize the current discount rate by viewing this display. Furthermore, by looking at this display, it can be determined whether to charge or to stop charging.

  In step p74, the charging device 11c determines whether a charging operation has been performed. When the charging operation is performed (YES in step p74), charging is started in step p75.

  After that, when the charging is finished, the charging device 11c detects the charging amount in the current charging in step p76, and transmits this data to the data center 12c via the network.

  At step q76, the data center 12c reads the transmitted charge amount. Further, in step q77, correction processing of the charge amount is performed. In this process, one week is divided into 21 time zones, and a busy time zone and a non-time zone are set according to the degree of congestion of the charging device 11c. Then, when charging during a busy time zone or a non-time zone, the charge amount is corrected. The details are as shown in FIG. 17 described above.

  At step q78, the data center 12c executes the process of updating the number of times of charging. In this process, when the charge on that day is the first time, the charge count is incremented, and after the second time, the charge count is incremented only when the threshold charge amount is exceeded. The details are as shown in FIG. 21 described above.

  Thereafter, in step q79, the data center 12c stores the accumulated charge amount and the accumulated charge number in the storage unit 34. As a result, the latest accumulated charge amount of the electric vehicle 13A and the accumulated charge number are overwritten and stored in the storage unit 34.

  Next, the data rewrite situation by the above process will be described with reference to the application table shown in FIG. For the electric vehicle 13A to be charged, when the accumulated charge amount before charging is 5500 [KWh] and the accumulated number of times of charging is 1300 times, the case where the electric energy of 20 [KWh] is charged in the current charging Suppose. In addition, it is assumed that the charge per unit power consumption is 50 yen.

  In this case, the discount rate is "0.8" in the correspondence table shown in FIG. Therefore, the charge fee is 20 * 50 * 0.8 = 800, which is 800 yen.

  Furthermore, since the charged time zone is 20 o'clock on Wednesday, as shown in FIG. Therefore, 20 [KWh] of the charge amount is multiplied by the correction coefficient β (= 2) to obtain 40 [KWh]. Then, by adding 40 [KWh] to the previous accumulated charge quantity, the accumulated charge quantity after charge becomes 5540 [KWh].

  In addition, since the number of times of charge on the day is the second time and the current charge amount is 20 [KWh] and exceeds the threshold charge amount of 15 [KWh], the cumulative charge count after charge is incremented, 1301 It will be times. Thus, the discount rate, that is, the incentive is set based on the accumulated charge amount and the accumulated charge number.

  In this manner, in the charging system 104 according to the fourth embodiment, the accumulated charge amount which is the accumulation of the electric energy charged in the past for each electric vehicle 13 and the accumulated number of times which is the accumulation of the number of times of charging in the past Are stored in the storage unit 34. Then, when the electric vehicle 13A to be charged is charged by the charging device 11c, the accumulated charge amount and the accumulated charge number of the electric vehicle 13A are read out, and the charge fee is calculated according to the accumulated charge amount and the accumulated charge number. Set the discount rate (incentive) of At this time, the discount rate is set to be higher as the accumulated charge amount and the accumulated charge number increase.

  Therefore, it is possible to give the occupants of the electric vehicle 13 a desire to further increase the accumulated charge amount and the accumulated charge frequency, and it is possible to increase the usage frequency of the charging device 11c provided in commercial facilities etc. It becomes.

  Furthermore, as in the second embodiment described above, the correction coefficient is set to be different depending on the low time zone and the busy time zone set for each charging device 11c. That is, when charging in the busy time zone, the charge amount smaller than the actual charge amount is added to the accumulated charge amount, and in the case of charging in the off time zone, the charge amount larger than the actual charge amount is cumulative It is added to the charge amount. Therefore, it is possible to give the occupants of the electric vehicle 13 a desire to charge in the off time zone while avoiding the busy time zone as much as possible, and it becomes possible to level out the congestion degree in each charging device 11c. .

  Further, since the discount rate information and the correction factor information are displayed on the display unit 24 of the charging device 11c, the occupant of the electric vehicle 13 can be made aware of the current discount rate and the correction factor. It can be made easy to judge whether or not to do it.

  In addition, if the electrically powered vehicle 13 is a charging device 11c connected to the data center 12 via a network, the accumulated charge amount and the accumulated number of times of charging can be updated regardless of which charging device 11c is charged. As it can be enhanced, the charging place is not limited and versatile.

  Also in the fourth embodiment, as shown in the first to third modifications of the first embodiment described above, the incentive may be set to a "multipurpose coupon ticket", a "charger priority use ticket", a "multipurpose point", etc. It is possible.

Description of Fifth Embodiment
Next, a fifth embodiment of the present invention will be described. In the first to fourth embodiments described above, the charging system calculates the accumulated charge amount or the accumulated number of times of charge by communicating between the charging device and the data center, and sets an incentive based on the information. Explained. On the other hand, in the fifth embodiment, the charging device 51 sets an incentive. The details will be described below.

  FIG. 27 is a block diagram showing the configuration of the charging device 51 according to the fifth embodiment. As shown in FIG. 27, the charging device 51 performs communication with the electric vehicle 13 or a communication unit 61 that performs communication with a portable terminal (for example, a smartphone) possessed by an occupant of the electric vehicle 13. Have. Further, when the electric vehicle 13 is connected by the charging cable, an ID recognition unit 62 (vehicle recognition unit) that communicates with the electric vehicle 13 and recognizes the ID of the electric vehicle 13 and the electric vehicle 13 are charged A charge amount detection unit 63 for detecting the amount of power consumption, and a display unit 64 for displaying various information such as information on incentives are provided. Furthermore, an accumulated charge amount calculation unit 65 that calculates an accumulated value of the charge amount by each electric vehicle 13, an incentive setting unit 66 that sets a discount rate (incentive) of the charge rate based on the accumulated charge amount, A storage unit 67 is provided to store various types of information including the information.

  The ID recognition unit 62, the charge amount detection unit 63, the accumulated charge amount calculation unit 65, and the incentive setting unit 66 may be, for example, an integrated type including storage means such as a central processing unit (CPU), RAM, ROM, hard disk, etc. It can be configured as a computer.

  The incentive setting unit 66 sets a discount rate based on the accumulated charge amount of each of the electric powered vehicles 13 with reference to the correspondence table of FIG. 3 described above. That is, the discount rate is set to be higher as the accumulated charge amount is larger.

  Next, the operation of the charging device 51 according to the fifth embodiment will be described with reference to the flowchart shown in FIG. First, in step S51, the charging device 51 receives a request signal of incentive information from the electric vehicle 13.

  When the request signal is received, the incentive information is transmitted to the request-source electric vehicle 13 in step S52. In the present embodiment, the incentive is a discount rate of the charge rate, and the discount rate is set to be higher as the accumulated charge amount increases. Specifically, the discount rate is set using the aforementioned FIG. 3 correspondence table. For example, when the accumulated charge amount of the request-source electric vehicle 13 is 5500 [KWh], it is recognized that the discount rate is "0.9" with reference to the correspondence table of FIG. This information is transmitted to the electric vehicle 13.

  In step S53, the charging device 51 confirms that the electric vehicle to be charged (referred to as 13A) is connected by the charging cable.

  In step S54, the charging device 51 confirms the ID of the electric vehicle 13A and identifies the vehicle. In step S55, the accumulated charge amount of the electrically powered vehicle 13A is read out from the storage unit 67.

  In step S56, the charging device 51 sets a discount rate (incentive) based on the accumulated charge amount. For example, as shown in FIG. 3, when the accumulated charge amount is 5500 [KWh], the discount rate is set to 0.9. In step S57, the charging device 51 displays information on the discount rate on the display unit 64.

  In step S58, the charging device 51 determines whether the charging operation has been performed. When the charging operation is performed (YES in step S58), charging is started in step S59.

  After that, when the charging is finished, in step S60, the charging device 11 detects the charging amount by the current charging, and adds it to the accumulated charging amount before the start of charging to obtain a new accumulated charging amount. For example, if the accumulated charge amount before charging is 5500 [KWh] and the current charge quantity is 20 [KWh], this is accumulated to obtain a new accumulated charge quantity of 5520 [KWh].

  In step S61, the charging device 11 overwrites and stores the new accumulated charge amount in the storage unit 67. By doing so, the storage unit 34 stores the latest accumulated charge amount of the electric vehicle 13A.

  Thus, in the charging device 51 according to the fifth embodiment, the accumulated charge amount, which is the total of the electric power amounts charged to the respective electric powered vehicles 13 in the past, is stored in the storage unit 67. Then, when a certain electric vehicle 13A is charged by the charging device 51, the accumulated charge amount of the electric vehicle 13A is read out, and a discount rate (incentive) of the charge fee is set according to the accumulated charge amount. At this time, the discount rate is set to be higher as the accumulated charge amount is larger.

  Therefore, it is possible to give the occupants of the electric vehicle 13A the desire to further increase the accumulated charge amount, and it is possible to increase the usage frequency of the charging device 51 provided in a commercial facility or the like.

  Further, since the discount rate information is displayed on the display unit 64 of the charging device 51, the driver of the electric vehicle 13 can be made to recognize the current discount rate, and it is easy to determine whether or not to charge. can do.

  Furthermore, since the charging device 51 and the electric vehicle 13 can communicate with each other via the network, when the request signal is transmitted from the electric vehicle 13, the charging device 51 provides an incentive for the electric vehicle 13 Provide information. Therefore, the present incentive information can be easily provided to the occupants of the electric vehicle 13, and the frequency of use of the charging device 11 can be further increased.

  Also in the fifth embodiment, as shown in the first to third modifications of the first embodiment described above, the incentives may be changed to "multipurpose coupon ticket", "charger priority use ticket", "multipurpose point", etc. It is possible.

  In the fifth embodiment, it is also possible to set an incentive by using the number of times of charging instead of the amount of charge. Furthermore, it is possible to set a busy time zone and a non-time zone, determine a correction coefficient, and correct the charge amount.

  As mentioned above, although the system of the present invention, the charge device, and the incentive setting method of electric vehicles were explained based on the embodiment of illustration, the present invention is not limited to this, and the composition of each part has the same function. It can be replaced with one having any configuration.

  For example, in each embodiment mentioned above, although the example which connects a charge cable to electrically powered vehicle 13 and charges it was explained, it is possible to apply also to the charge device which adopts the non-contact charge method.
