Description

  The present invention relates to an information providing device that provides information related to lending of a vehicle equipped with a battery, a charging device including the information providing device, a computer program for realizing the information providing device, and an information providing method.

  In recent years, from the viewpoint of environmental protection or effective use of limited resources, there is an expectation for an electric vehicle (EV: Electric Vehicle) that runs on a motor using electricity charged from the outside as a power source instead of a vehicle that uses gasoline. It is growing.

  On the other hand, expansion of the charging infrastructure for charging electric vehicles is also an important issue. In addition to installing charging facilities in the parking lots of individual houses, a plurality of electric vehicles can be installed in the charging facilities provided in the common spaces of apartment buildings. A system such as so-called car sharing, in which an electric vehicle is lent to a plurality of users, is also being studied.

  For example, when an electric vehicle is shared (car sharing) among residents (users) of an apartment house, ID information read by authentication by an authentication means presented by the resident permits charging of the electric vehicle. When it is good ID information, the charging system which controls charge of an electric vehicle by a charge control part is disclosed (refer patent document 1).

JP2013-51874A

  However, in the conventional car sharing disclosed in Patent Document 1, the charge when each user borrows an electric vehicle is set according to the rental time of the electric vehicle. For this reason, for example, when the lending time of a user who uses a large amount of power is the same as the lending time of a user who uses a small amount of power, each user will pay the same amount of money. For a small number of users, the fee was expensive, and the information provided regarding the rental of the vehicle such as a rental fee was unfair.

  The present invention has been made in view of such circumstances, and to realize an information providing apparatus capable of providing fair information regarding vehicle lending, a charging device including the information providing apparatus, and the information providing apparatus. It is an object to provide a computer program and an information providing method.

  An information providing apparatus according to the present invention is an information providing apparatus that provides information related to lending of a vehicle equipped with a battery, and is acquired by a charging rate acquiring unit that acquires a charging rate of the battery and the charging rate acquiring unit when the vehicle is lent And a calculating unit that calculates a charge related to the lending of the vehicle based on the charging rate at the time of lending and the charging rate at the time of return acquired by the charging rate acquisition unit when the vehicle is returned.

  The charging device according to the present invention includes the information providing device according to the above-described invention.

  A computer program according to the present invention is a computer program for causing a computer to provide information related to lending of a vehicle equipped with a battery. The computer is acquired when a vehicle is rented, and a charge rate acquiring unit that acquires the charge rate of the battery. It is made to function as a calculation part which calculates the charge regarding the rental of the said vehicle based on the charging rate at the time of lending and the charging rate at the time of return acquired at the time of return of the vehicle.

  An information providing method according to the present invention is a method of providing information related to lending of a vehicle equipped with a battery, wherein the charging rate acquisition unit acquires a charging rate of the battery, and at the time of lending acquired at the time of lending the vehicle A calculating unit calculating a charge related to the lending of the vehicle based on a charging rate and a charging rate at the time of return acquired when the vehicle is returned.

  In this invention, a charge rate acquisition part acquires the charge rate of a battery from the vehicle carrying this battery. The charging rate can be, for example, a ratio of the actual remaining capacity of the battery to the charging capacity of the battery in a fully charged state or a state where the charging upper limit value has been reached, and an index indicating how much charging is completed It is. The calculation unit calculates a charge related to the lending of the vehicle based on the charging rate at the time of lending acquired from the vehicle at the time of lending the vehicle and the charging rate at the time of return acquired from the vehicle at the time of returning the vehicle. For example, the charge can be calculated based on the difference between the charging rate at return and the charging rate at lending. As a result, the higher the amount of power used by the battery, the higher the fee, and the lower the amount of power used, the lower the fee, thereby providing fair information regarding vehicle lending.

  The information providing apparatus according to the present invention includes a specifying unit that specifies a difference according to a difference between the charge rate at return and the charge rate at lending, and the calculation unit includes the fee based on the difference specified by the specifying unit. Is calculated.

  In this invention, a specific part specifies the difference according to the difference of the charging rate at the time of return, and the charging rate at the time of rental. The difference according to the difference in charging rate may be stored in advance as a table, or the difference according to the difference in charging rate may be obtained by calculation. The calculation unit calculates a fee based on the difference specified by the specifying unit. Thereby, a charge is computable based on the difference of the charging rate at the time of return, and the charging charge rate at the time of rental.

  The information providing apparatus according to the present invention is characterized in that, when the charge rate at return is larger than the charge rate at lending, the calculation unit calculates the fee by reducing the difference specified by the specifying unit. .

  In the present invention, when the charge rate at the time of return is larger than the charge rate at the time of lending, the calculation unit calculates a fee by reducing the difference specified by the specifying unit. For example, when the user charges the battery with another charging facility during lending, and the charging rate at return is larger than the charging rate at lending, the difference based on the difference in charging rate is reduced from the charge. As a result, the user has a willingness to charge while renting, the possibility that the charging rate is high when returning the vehicle is high, and the time required to fully charge when charging at the return place Shorten or reduce the amount of charge, as a result, shorten the charging completion time at the return place, increase the number of vehicles that can be rented, or shorten the charging waiting time at the time of renting it can.

  The information providing apparatus according to the present invention is characterized in that, when the charge rate at return is smaller than the charge rate at lending, the calculating unit calculates the fee by increasing the difference specified by the specifying unit. .

  In the present invention, when the charging rate at the time of return is smaller than the charging rate at the time of lending, the calculation unit calculates a fee by increasing the difference specified by the specifying unit. When the charge rate at the time of return is smaller than the charge rate at the time of lending, the difference based on the difference in charge rate is increased. As a result, the fee is not set based only on the lending time, but is increased according to the amount of power used, so that unfairness among users can be eliminated.

  In the information providing apparatus according to the present invention, the specifying unit specifies the difference based on a difference between the charging rate at return and a charging rate at lending and a predetermined weighting factor, and the charging rate at return is the charging at lending. The weighting coefficient when larger than the rate is larger than the weighting coefficient when the return charging rate is smaller than the lending charging rate.

  In the present invention, the specifying unit specifies the difference based on the difference between the charging rate at return and the charging rate at lending and a predetermined weighting factor. For example, the difference amount can be specified as an electric charge × a charge amount corresponding to a difference of a charging rate × weighting coefficient. And the weighting coefficient when the charging rate at return is larger than the charging rate at lending is larger than the weighting coefficient when the charging rate at return is smaller than the charging rate at lending. If the charge rate at the time of return is greater than the charge rate at the time of lending, it will be reduced, and if the charge rate at return is less than the charge rate at the time of lending, it will be increased, so even if the difference is the same, the amount to be reduced will be increased It becomes more than an amount of money, and it can promote that a user charges with another charging equipment before returning vehicles.

  The information providing apparatus according to the present invention includes an output unit that outputs at least one of the fee calculated by the calculating unit and the difference specified by the specifying unit.

  In the present invention, the output unit outputs at least one of the fee calculated by the calculation unit and the difference specified by the specifying unit. For example, the output unit may be a display unit that is mounted on a vehicle and displays characters or graphics, or a speaker that outputs sound. Thereby, the user who drives the rented vehicle can confirm the fee or the difference (decrease or increase), and the convenience of the user can be improved. Moreover, you may make it mount an output part in the charging device which charges a battery. In this case, the user cannot confirm the fee or the difference during driving, but no modification for attaching a display unit or a speaker to the vehicle is required.

  An information providing apparatus according to the present invention charges an information acquisition unit that acquires information about a user to whom the vehicle is lent, and a charge calculated by the calculation unit to a user who has acquired information by the information acquisition unit And a generation unit for generating billing information as much as possible.

  In this invention, an information acquisition part acquires the information (user information) regarding the user from whom a vehicle is lent. The user information can be ID information for identifying the user, for example. The generating unit generates charging information so as to charge the user who has acquired information by the information acquiring unit with the fee calculated by the calculating unit. The billing information is, for example, a monthly payment fee. For example, a monthly basic fee (monthly fee) + a fee based on the usage time (lending time) in the current month + a charge based on the difference between the charging rates (a reduced fee and Information such as the amount offset). Thereby, it is possible to charge for each user.

  According to the present invention, it is possible to provide fair information regarding vehicle lending.

The information providing apparatus 10 can be connected to the charging apparatus 20 via the communication network 1 such as the Internet or a telephone line.

  For example, the charging device 20 is installed in a parking lot and controls the entire device, a communication unit 22, a card reading unit 23, an operation unit 24, an interface unit 25, a charging unit 26, an authentication unit 27, and a key box 28. Etc. The charging device 20 includes a charging cable 2 including the communication line 3 and the power line 4, and can connect the charging cable 2 to the electric vehicle 50.

  The electric vehicle 50 is a vehicle that is used for car sharing, and includes a control unit 51 that mainly controls processing related to charging, an interface unit 52, a relay 53, a battery 54, a charging rate detection unit 55, and the like.

  The interface unit 52 of the electric vehicle 50 is for transmitting and receiving information to and from the charging device 20 (interface unit 25) via the communication line 3 in the charging cable 2.

  The relay 53 is interposed in the power line 4 between the charging unit 26 of the charging device 20 and the battery 54, and is closed when charging the battery 54 under the control of the control unit 51. Sometimes it is open.

  The charging rate detection unit 55 detects the charging rate of the battery 54 under the control of the control unit 51. The charging rate can be, for example, a ratio of the actual remaining capacity of the battery 54 to the charging capacity of the battery 54 in a fully charged state or a state where the charging upper limit value is reached, and how much charging is completed. It is an index to represent.

  The control unit 51 transmits the charging rate detected by the charging rate detection unit 55 (for example, the charging rate during lending and the charging rate during return) to the charging device 20 (interface unit 25) via the interface unit 52.

  The interface unit 25 of the charging device 20 transmits and receives information to and from the electric vehicle 50 (interface unit 52) via the communication line 3 in the charging cable 2.

  The charging unit 26 includes a charging circuit for charging the battery 54, converts alternating current from a power source (not shown) (for example, commercial power source) into direct current, and converts the direct current converted through the power line 4 to the electric vehicle 50. Output.

  The communication unit 22 transmits and receives information to and from the information providing apparatus 10 (communication unit 12) via the communication network 1.

  The card reading unit 23 reads user information (for example, ID information for identifying the user) recorded on the ID card carried by the user.

  The authentication unit 27 authenticates whether the user information read by the card reading unit 23 is registered in advance and the user is allowed to share the car.

  The operation unit 24 includes an operation panel and can accept a lending operation, a return operation, a charge start operation, a charge stop operation, and the like of the electric vehicle 50.

  The key box 28 can accommodate the key of the electric vehicle 50. When the authentication unit 27 authenticates the user as the correct user, the key box is unlocked, and the user takes out the key or stores the key. Can do. Note that the key box 28 is an example, and the method by which the user receives the key is not limited to this. If the user is authenticated as the correct user, the key may be received by hand from the administrator.

  The control unit 21 performs control so that a charge rate request is transmitted to the electric vehicle 50 via the interface unit 25 when a lending operation or a return operation is performed by the operation unit 24 and a user ID is authenticated by the authentication unit 27. To do. In this case, when receiving the charging rate request, the control unit 51 of the electric vehicle 50 controls to transmit the charging rate information detected by the charging rate detection unit to the charging device 20.

  The communication unit 12 of the information providing apparatus 10 transmits and receives information to and from the charging device 20 (communication unit 22) via the communication network 1. The communication unit 12 has a function as a charging rate acquisition unit, and acquires a charging rate indicating the remaining capacity of the battery 54 from the electric vehicle 50 equipped with the battery 54 via the charging device 20. Moreover, the communication part 12 has a function as an information acquisition part, and acquires the information (user information) regarding the user from whom the electric vehicle 50 is lent.

  The calculation unit 14 calculates a charge related to the lending of the electric vehicle 50 based on the charging rate at the time of lending when the electric vehicle 50 is lent and the charging rate at the time of return acquired when the electric vehicle 50 is returned.

  FIG. 2 is an explanatory diagram illustrating an example of a charge related to lending an electric vehicle 50 that is an example of information provided by the information providing apparatus 10 of the first embodiment. As shown in FIG. 2, the breakdown of the charges related to the lending of the electric vehicle 50 is, for example, a fee charged monthly to the user lending the electric vehicle 50, and the monthly basic fee A and monthly The total amount of the charge B based on the usage time (lending time) of the electric vehicle 50, the charge C when returning, and the charge C based on the difference between the charging charge rate when renting. Thus, the charge is not simply set according to the use time (lending time), but the charge is increased as the amount of power of the battery 54 used is increased, and the charge is reduced as the amount of power used is decreased. Therefore, it is possible to provide fair information regarding the lending of the electric vehicle 50.

  The specifying unit 13 specifies a difference according to the difference between the charging rate at return and the charging rate at lending. The difference according to the difference in the charging rate may be stored in advance in the storage unit 16 as a table, or the difference according to the difference in the charging rate may be obtained by calculation.

  The calculating unit 14 calculates a fee based on the difference specified by the specifying unit 13. Thereby, a charge can be calculated based on the difference between the charging rate at return and the charging rate at lending.

  More specifically, when the charge rate at return is smaller than the charge rate at lending, the calculation unit 14 calculates a fee by increasing the difference specified by the specifying unit 13. Moreover, the calculation part 14 reduces a difference specified by the specific | specification part 13, and calculates a charge, when the charging rate at the time of return is larger than the charging rate at the time of rental.

  FIG. 3 is an explanatory diagram illustrating an example of setting a charge based on a charging rate using an electricity charge by the information providing apparatus 10 of the first embodiment. FIG. 3 shows an example in which the charge C based on the charging rate is set using the electricity charge. First, the charge table T1 is used when the charge rate at the time of return is smaller than the charge rate at the time of loan (charge rate at the time of return <charge rate at the time of loan), and the calculation formula by the charge table T1 is: difference = electricity charge × charge rate The amount of power corresponding to the difference × weighting coefficient α.

  For example, if the electricity rate is 30 yen per kWh and the charging rate at the time of return is 40% reduced, assuming that the 40% reduction in charging rate corresponds to, for example, 10 kWh, the difference is 30 × 10 × α. Become. If α = 0.7, the difference is an increase of 210 yen.

  When the charge rate at the time of return is smaller than the charge rate at the time of lending, the charge C based on the charge rate becomes an increase C1. If the charging rate at the time of return is smaller than the charging rate at the time of lending, the difference based on the difference in charging rate is increased, so the charge is not set based on the lending time alone, but is increased according to the amount of power used. Therefore, it is possible to eliminate unfairness among users.

  The charge table T2 is used when the charge rate at the time of return is larger than the charge rate at the time of loan (charge rate at the time of return> charge rate at the time of loan), and the calculation formula by the charge table T2 is: difference = electricity charge × charge rate The amount of power corresponding to the difference × weighting coefficient β.

  For example, if the electricity rate is 30 yen per kWh and the charging rate at the time of return is 40% increase, assuming that the 40% increase in charging rate corresponds to, for example, 10 kWh, the difference is 30 × 10 × β Become. If β = 0.7, the difference is reduced by 210 yen.

  For example, when the user charges the battery 54 with another charging facility during lending, and the charging rate at return is larger than the charging rate at lending, the difference based on the difference in charging rate is reduced from the charge. As a result, the user has a willingness to charge while renting, and there is a high possibility that the charging rate is high when the electric vehicle 50 is returned, and it is necessary to fully charge when charging at the return place. The time is shortened or the amount of charge is reduced. As a result, the charging completion time at the return place can be shortened, the number of electric vehicles 50 that can be lent can be increased, or the charging waiting time at the time of renting can be reduced. Can be shortened.

  As described above, according to the present embodiment, when the charging rate of the battery 54 at the time of return is increased, the charge related to lending is reduced according to the difference in the charging rate. There is a willingness to charge before returning, or a willingness to return before the charging rate drops. Thereby, if the charging rate of the returned electric vehicle becomes large, it can be immediately lent to the next user without charging at the return place, and the number of vehicles waiting for charging can be reduced. Even when charging is performed at the return place, since the charging rate is large, charging can be completed in a short time, and the number of electric vehicles that can be rented can be constantly increased.

  Further, in an apartment house such as a condominium, the upper limit value of the current capacity of the entire apartment house is set, and if the current when charging the electric vehicle exceeds the upper limit value, the electric vehicle cannot be charged. According to the present embodiment, it is possible to increase the possibility that the charging rate at the time of return can be increased, so that charging can be completed in a relatively short time even if the charging current is somewhat reduced. By reducing the charging current of each electric vehicle, the number of electric vehicles that can be charged at the same time can be increased more than before.

  In the above example, the weighting coefficients α and β are the same value. However, the present invention is not limited to this. For example, the weighting coefficient β when the charge rate at return is larger than the charge rate at rental is charged at return. The rate can be larger than the weighting coefficient α when the charging rate is smaller than the lending charging rate. For example, α = 0.7 and β = 1.0 can be set. In this case, assuming that the electricity rate is 30 yen per kWh and the charge rate at the time of return is 40% increase, assuming that the 40% increase in the charge rate corresponds to, for example, 10 kWh, the difference is 30 × 10 × β It becomes. If β = 1.0, the difference is reduced by 300 yen.

  Thus, even if the difference in charging rate when the charging rate at return is larger than the charging rate at lending and the difference in charging rate when the charging rate at return is smaller than the charging rate at lending are the same difference, it is reduced. Therefore, the user can be encouraged to charge with another charging facility before the electric vehicle 50 is returned.

  In the above-described example, the example in which the electric charge is used when setting the charge based on the difference in the charging rate has been described, but the present invention is not limited to this. FIG. 4 is an explanatory diagram showing an example of setting a charge based on the charging rate using the charging time by the information providing apparatus 10 of the first embodiment. FIG. 4 shows an example in which the charge C based on the charging rate is set using the charging time. First, the charge table T1 is used when the charge rate at the time of return is smaller than the charge rate at the time of lending (charge rate at the time of return <charge rate at the time of lending). X Weighting coefficient α.

  For example, assuming that the lending time fee per hour is 500 yen, the charging rate at the time of return is reduced by 30%, and the charging time required to charge 30% is 15 minutes, the difference is 500 × (15/60) × α. If α = 0.8, the difference is an increase of 100 yen.

  The charge table T2 is used when the charge rate at the time of return is larger than the charge rate at the time of loan (charge rate at the time of return> charge rate at the time of loan), and the calculation formula by the charge table T2 is: difference = lending time charge × charge time X Weighting coefficient β.

  For example, assuming that the lending time fee per hour is 500 yen, the charging rate at the time of return has increased by 30%, and the charging time required to charge 30% is 15 minutes, the difference is 500 × (15/60) × β. If β = 0.8, the difference is reduced by 100 yen. In the example of FIG. 4 as well, as in the example of FIG. 3, the weighting coefficient β when the charge rate at return is larger than the charge rate at loan is the weighting coefficient β when the charge rate at return is less than the charge rate at loan. It may be larger than α.

  In the case of the example of FIG. 4, since the difference is calculated according to the charging time at the time of return, the charge is not known unless the charge is completed, so the user is informed of the charge after returning the electric vehicle. On the other hand, in the example of FIG. 3, since the difference is calculated according to the charging rate, the user's convenience is improved because the charge is known at the time of return. However, even in the example of FIG. 4, the difference can be calculated by setting the time obtained by dividing the amount of power required for charging by the rated output of the quick charger as the charging time. In that case, the fee can be notified immediately upon return.

  The display unit 17 has a function as an output unit, and can display at least one of the fee calculated by the calculation unit 14 and the difference specified by the specifying unit 13. The display unit 17 may be mounted on the charging device 20 that charges the battery 54. In this case, the user cannot confirm the fee or the difference during driving, but no modification for attaching a display unit or a speaker to the vehicle is required.

  The generation unit 15 generates billing information so as to charge the fee calculated by the calculation unit 14 to the user who has acquired information by the communication unit 12. The billing information is, for example, a monthly payment fee. For example, a monthly basic fee (monthly fee) + a fee based on the usage time (lending time) in the current month + a charge based on the difference between the charging rates (a reduced fee and Information such as the amount offset). The billing information generated by the generation unit 15 can be transmitted to a mobile phone, a smartphone, a tablet terminal, a personal computer, or the like carried by the user. Further, the billing information may be mailed to the user's address. Thereby, it is possible to charge for each user.

  Next, the operation of the billing system of this embodiment will be described. FIG.5 and FIG.6 is a flowchart which shows an example of the process sequence of the charging device 20 of 1st Embodiment. In the following, the processing subject will be described as the control unit 21 for convenience. The control unit 21 determines whether or not the electric vehicle 50 (EV) is lent (S11). If there is no rent operation (NO in S11), the control unit 21 continues the process of step S11. When there is a lending operation (YES in S11), the control unit 21 acquires user information (S12) and performs ID authentication (S13).

  When the ID authentication is correctly performed, the control unit 21 requests the charging rate from the electric vehicle 50 (S14), determines whether or not the charging rate is acquired from the electric vehicle 50 (S15), and determines the charging rate. If not acquired (NO in S15), the process of step S15 is continued.

  When the charging rate is acquired (YES in S15), the control unit 21 transmits user information, lending time (date and time), and charging rate (lending charging rate) to the information providing apparatus 10 (S16). The control unit 21 determines whether or not the lending operation is finished (S17). When the lending operation is not finished (NO in S17), the process of step S17 is continued.

  When the lending operation is completed (YES in S17), the control unit 21 determines whether or not the electric vehicle 50 (EV) is returned (S18). When there is no return operation (NO in S18), the process of step S18 is performed. Continue. During this time, the user uses the rented electric vehicle 50. When there is a return operation (YES in S18), the control unit 21 acquires user information (S19) and performs ID authentication (S20).

  If ID authentication is performed correctly, the control part 21 will request | require a charging rate with respect to the electric vehicle 50 (S21), it will be determined whether the charging rate was acquired from the electric vehicle 50 (S22), and a charging rate will be determined. If not acquired (NO in S22), the process of step S22 is continued.

  When the charge rate is acquired (YES in S22), the control unit 21 transmits the user information, the return time (date and time), and the charge rate (return rate charge rate) to the information providing apparatus 10 (S23). The control unit 21 determines whether or not the return operation has ended (S24). If the return operation has not ended (NO in S24), the process of step S24 is continued. When the return operation is completed (YES in S24), the control unit 21 ends the process.

  FIG. 7 is a flowchart illustrating an example of a processing procedure of the information providing apparatus 10 according to the first embodiment. In the following, the processing subject will be described as the control unit 11 for convenience. The control unit 11 receives user information, lending time (date and time), and charging rate (charging rate at lending) (S41), and receives user information, return time (date and time), and charging rate (charging rate at returning) (S41). S42).

  The control unit 11 calculates the usage time (lending time), calculates the charge B according to the usage time (S43), and compares the charging rate at return and the charging rate at lending (S44). The control unit 11 determines whether or not the charging rate at return is smaller than the charging rate at lending (S45), and when the charging rate at return is smaller than the charging rate at lending (YES in S45), the difference in charging rate An increase fee C1 corresponding to the fee is specified (S46), and a rental fee (= charge B + an increase fee C1) is calculated (S47).

  When the charging rate at the time of return is not smaller than the charging rate at the time of lending (NO in S45), the control unit 11 specifies a reduction fee C2 corresponding to the difference in the charging rate (S48), and the lending fee (= fee B-reduction) Charge C2) is calculated (S49).

  The control part 11 classify | categorizes for every user, and memorize | stores the charge information regarding the calculated rental charge in the memory | storage part 16 (S50). The control unit 11 determines whether or not it is a charge billing timing (for example, the end of the month) (S51).
