Abstract

PROBLEM TO BE SOLVED: To provide a charging power supply system capable of suppressing complication and increase of facility scale and cost increase, for a high operation rate as a whole.SOLUTION: The AC power inputted from a commercial AC power source 2 is allocated in ten streams by a power distributor 3, and each of which is converted to DC power at rectifiers 11-20, and is then inputted in a switcher 4. The switcher 4 can switch destinations of respective power from the rectifiers 11-20 to either of ten output terminals 31-40. Consequently, an output of charging power corresponding to a charging menu is available from the output terminals 31-40. For example, if a middle-speed charging (requires the amount of electric power corresponding to three rectifiers) is selected at a first charging stand 51, a control device 5 controls the switcher 4 to cause the input power from the first rectifier 11 to the third rectifier 13 among others, three in all, to be outputted from the first output terminal 31. A charging rate is calculated and charged according to a charging menu (high speed/middle speed/low speed).

Description

  The present invention relates to a charging power supply system that supplies electric power for charging a storage battery such as an electric vehicle to a vehicle that runs using the electric power of the storage battery as a drive source.

  In recent years, environmental problems and energy resource problems have attracted attention, and so-called electric vehicles, plug-in hybrid vehicles, and the like, vehicles that can run using the power of a storage battery as a driving source are being promoted.

  Although this type of vehicle depends on the capacity of the storage battery, the cruising distance is shorter than that of a conventional vehicle that travels using an internal combustion engine as a drive source. Therefore, in order to widely disseminate electric vehicles and the like, it is an urgent issue to improve the charging infrastructure.

  Charging infrastructure for electric vehicles, etc., as a conventional charging station, such as a charging station configured with a plurality of charging stations and capable of individually charging a plurality of vehicles, commercial facilities, etc. Various forms have been proposed, such as a form that can be charged while parking by a charging stand provided in a parking lot, and some have already been put into practical use.

  As an example of the above-described charging station, Patent Literature 1 describes a power supply system that includes a plurality of connection functions (charging stations) and is configured to be able to supply charging power to a vehicle for each charging station.

  In the power supply system described in Patent Document 1, commercial power input from the outside is distributed to each charging station. Further, in this Patent Document 1, an identity verification signal held in a vehicle when a user registers an identity and a fee settlement method in advance in a management station or when the vehicle and a charging stand are electrically connected. Is acquired and transmitted to the management station, etc., and charging is possible when approved by the management station, etc., and the charge amount detection result is transmitted to the management station, etc. It is also described that the calculation etc. is performed.

JP 2007-66278 A

  By the way, some users who want to charge an electric vehicle at a charging station have a user who wants to complete charging in a short time (in a short time), and another user who can take several hours. It is expected that the charging time and charging speed to be used vary widely depending on the user.

  In order to respond to such diverse needs, for example, in a charging station, there are a quick charging stand capable of rapid charging in a short time (for example, 1 hour) and an ordinary charging stand that performs slow charging over several hours. It is conceivable to provide two types (or more) of charging stations.

  However, such a configuration in which a dedicated charging stand is provided for each charging speed leads to a complicated equipment configuration of the entire charging station and an increase in cost. Moreover, since the charging power that can be supplied from each charging station is predetermined for each charging station, there is a risk that the operating rate of the entire charging station will deteriorate. The “operation rate” means a ratio of power actually supplied to the electric vehicle out of all power that can be supplied in the entire charging station (or an average value of the ratio per certain period).

  As a specific example, there is a charging station that is capable of supplying charging power of 100 kW as a whole, and has one quick charging station with a maximum output power of 50 kW and five ordinary charging stations with a maximum output power of 10 kW. Is assumed.

  In this charging station, even if two vehicles (users) that desire rapid charging enter at the same time, there is only one rapid charging station of 50 kW, so only one of the vehicles can perform rapid charging. In other words, the charging station as a whole has a power supply capacity of 100 kW (for two quick charging units), but 50 kW is distributed among five ordinary charging stations. It is not possible. Therefore, in this case, the five ordinary charging stations are not used effectively, leading to a reduction in operating rate.

  Conversely, when all five normal charging stations are in use and a new user who wants normal charging comes in, the new user cannot charge with normal charging. You will be forced to find another charging station or to quickly charge at an empty quick charging station. In the former case, the user's wish cannot be satisfied despite the remaining capacity to supply power of 50 kW, and as a result, the operating rate is lowered. In the latter case, charging can be completed more quickly, but by using a quick charging stand, depending on the billing method, it is possible to pay a charging fee that is higher than originally assumed. Forced.

  In order to give priority to normal charging, there is a method of preparing a larger number of normal charging stations, but of course, it becomes difficult to cope with an increase in users who desire quick charging, and there is still a lot of available capacity as power capacity. However, the amount cannot be applied to rapid charging, and the operating rate may be reduced. Conversely, in order to give priority to quick charging, the same applies to a case where a large number of quick charging stations are prepared. Naturally, it becomes difficult to cope with an increase in users who desire normal charging, and there is a possibility of causing a reduction in operating rate. .

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a charging power supply system having a high operating rate as a whole while suppressing the complexity, enlargement, and cost increase of the facility scale.

  The invention according to claim 1, which has been made in order to solve the above problem, is a charging power supply system for supplying charging power of a storage battery to a vehicle that travels using the power of the storage battery as a drive source. A plurality of power supply means capable of supplying power, a plurality of charging power output terminals for outputting charging power to the vehicle, and power from the plurality of power supply means are respectively input, and output destinations of the input power are individually set. Switching means configured to output input power from one or more power supply means as charging power from one charging power output terminal by switching to any one of the plurality of charging power output terminals; Each charging power output terminal includes charging request receiving means for receiving a charging request to the vehicle, and charging control means.

  When a charge request is accepted by the charge request accepting means, the charge control means uses a predetermined number of power supply means corresponding to the charge request as a supply source, and the charge output destination from the supply source corresponds to the charge control means The switching means is controlled to switch to the power output terminal, and the vehicle is charged from the charging power output terminal by controlling the power supplied from the supply source.

  The charging power supply system configured as described above includes a plurality of power supply means that can supply power for charging. However, as in the past, charging power is supplied to each vehicle one-on-one from the power supply means. Instead of being fixed, the switching means can supply power from one or more power supply means to one vehicle (one charging power output terminal).

  Therefore, for example, one charging power output terminal outputs power from one power supply means to perform charging, while another charging power output terminal outputs from two (or more) power supply terminals. It is possible to flexibly correspond to the charging power for each charging power output terminal (that is, for each vehicle / user), for example, to output electric power all at once and perform more rapid charging.

  That is, the output power is not fixed for each charging power output terminal, but the output power from each charging power output terminal can be appropriately switched by the switching means. Therefore, as long as there are unused power supply means other than the power supply means that are already used for charging, charging can be performed at the charging power and charging speed desired by the user within the range of the number.

  Therefore, according to the charging power supply system of the first aspect, the output destination of the power from the plurality of power supply means can be flexibly switched by the switching means, so that the facility scale becomes complicated, large, cost It is possible to provide a charging power supply system having a high operating rate as a whole while suppressing the increase.

  Next, the invention according to claim 2 is the charging power supply system according to claim 1, wherein the maximum power that can be output from the charging power output terminal to the vehicle is used as a charging menu when charging the vehicle. Different types of charging menus are set. Further, the charging request receiving means can receive the selection of the charging menu together with the charging request. When the charge request is accepted by the charge request accepting means, the charge control means supplies a predetermined number of power supply means necessary for output of the charge power corresponding to the charge menu selected by the charge request. The original.

  According to the charging power supply system according to claim 2 configured as described above, since the charging can be performed by selecting a desired charging menu for each charging power output terminal, the type and number of charging menus are set. By setting appropriately, a charging power supply system that is highly convenient for the user can be constructed.

  In addition, when a charge request is newly received with respect to the charge power output terminal to which charge power is not output, the charge control means is the power that is not supplying power at the time of reception as described in claim 3. A predetermined number of power supply means necessary for outputting charging power corresponding to the charging menu selected by the charge request may be selected as the supply source.

  Next, the invention according to claim 4 is the charging power supply system according to claim 2 or claim 3, wherein the charging state of the storage battery in the vehicle to be charged is detected for each of the plurality of charging power output terminals. And when the charging of the vehicle is started by a charge request at any of the charging power output terminals, the charging state detection means corresponding to the charging power output terminal is detected at a predetermined detection timing. And necessary power detecting means for detecting power necessary for charging after the detection timing based on the charged state.

  Then, the charging control means, after the start of charging by a predetermined number of supply sources corresponding to the charging menu selected in the charge request, at the predetermined comparison timing, the current supply number that is the number of the current supply sources, and necessary Compare the required supply number, which is the number of power supply means necessary to output the power detected by the power detection means, and if the current supply number is greater than the required supply number, the number of supply sources is required Control to be the number of supplies.

  That is, when charging the storage battery, although it depends on the charging method, it is generally not always necessary to supply constant power from the start to the end of charging, and the required power decreases as the charging proceeds. For example, in the case of the well-known constant voltage constant voltage (CVCC) type charging, the charging current decreases during the constant voltage charging period in the latter stage of charging. Will also decline.

  Therefore, instead of charging using a predetermined number of supply sources corresponding to the charging menu in the entire period from the start to the end of charging, if the actual required supply number becomes less than the current supply number due to the progress of charging , Reduce the number of suppliers to the required supply. In this way, the reduced amount can be used for charging other users.

  Therefore, according to the charge power supply system of the fourth aspect, the number of supply sources (power supply means) that supply the charge power can be controlled to an appropriate number according to the progress of the charge. Can be further enhanced.

  Next, the invention according to claim 5 is the charging power supply system according to any one of claims 2 to 4, wherein for each charging power output terminal where charging is performed, Supply source increase possibility determination means for determining whether or not charging can be performed with a larger number of power supply means than supply sources is provided. If it is determined by the supply source increase availability determination means that there is a power supply means that is not supplying power, the charge control means determines at least one of the power supply means as a service. As a supply means, add to the supplier.

  In other words, charging is performed from the number of suppliers according to the selected charging menu, but depending on the charging status, it is possible to perform charging using more power supply means. Is also expected. In such a case, if there is another power supply means that is not used, charging is performed using the unused power supply means (as a service supply means). That is, charging is performed with a larger number of supply sources than the normal number corresponding to the selected charging menu.

  Therefore, according to the charging power supply system of the fifth aspect, as long as there is an unused power supply means, it is possible to receive power supply from the service supply means depending on the charging status etc. Charging can be completed in a time shorter than the charging time originally required for charging the menu, so that convenience for the user can be further improved and high satisfaction can be given to the user.

  However, the service supply means is used only when there is another power supply means that does not need to supply power. For this reason, after a certain power supply means starts operating (power supply) as a service supply means, a new charge request makes it necessary to provide the service supply means in addition to the vacant power supply means at that time. In this case, for example, as described in claim 6, the service supply means may be operated for the new charging by stopping the operation as the service supply means.

  That is, the invention according to claim 6 is the charging power supply system according to claim 5, wherein when the charging request is received by the charging request receiving means, the charging menu selected by the charging request is used. A request response availability determination unit that determines whether or not charging can be newly performed is provided. The charge control means corresponds to the charge menu selected in the charge request only when the charge request is accepted by the charge request accepting means and only the power supply means not supplying power at the time of acceptance. If the predetermined number is not satisfied and there is a power supply means operating as a service supply means and if it is added, if the predetermined number is satisfied, the service supply means is connected to the power supply means that is not supplying the power. In addition, the supply source corresponds to the charging request.

  According to the charging power supply system according to claim 6 configured as described above, the operation as the service supply means is limited to a case where there is a margin (vacant) in the power supply means. As long as there is a vacancy, the user who is charging can finish charging more quickly without affecting the availability of charging.

  By the way, when a charge request is newly made at a certain charge power output terminal, it is expected that the new charge cannot be performed immediately depending on the presence or absence of charge at other charge power output terminals. In such a case, for example, if it has the structure as described in claim 7 to claim 11, appropriate measures can be taken.

  First, the invention according to claim 7 is the charging power supply system according to any one of claims 2 to 5, wherein the charging request is received when the charging request is received by the charging request receiving means. A request response availability determination unit that determines whether or not the charge menu selected by the request can be executed, and when the request response availability determination unit determines that the charge menu cannot be executed, the charge menu is charged. Charging impossible information output means for outputting charging impossible information indicating that it cannot be performed.

According to the charging power supply system of the seventh aspect configured as described above, the user can surely know whether or not charging is possible using the charging menu selected by the user.
In addition, as described in claim 8, the charging power supply system described in claim 6 may be provided with a non-chargeable information output unit similar to that in claim 7, in which case the above claim is included. The same effect as 7 can be obtained.

  Further, the invention according to claim 9 is the charging power supply system according to claim 7 or claim 8, wherein the selected charging is performed when it is determined that the request response availability determination means is not executable. Other menu executable information output means for outputting other menu executable information indicating that there is an executable menu other than the menu is provided.

  According to the charging power supply system according to claim 9 configured as described above, when the user cannot immediately perform charging in the charging menu selected by the user, the user simply does not (cannot perform charging). Not only can you know, but you can also know what other chargeable menus are feasible. Therefore, user convenience can be further enhanced.

  The invention according to claim 10 is the charging power supply system according to any one of claims 7 to 9, wherein the charging is required for each of the currently executed chargings to be completed. When it is determined by the required time predicting means that predicts the time and the request response availability determining means is not feasible, the charging in the selected charging menu is performed based on each required time predicted by the required time predicting means. Waiting time prediction means for predicting waiting time until it becomes possible, and waiting time information output means for outputting waiting time information indicating the waiting time predicted by the waiting time prediction means are provided.

  According to the charging power supply system according to claim 10 configured as described above, when the user cannot immediately perform charging in the charging menu selected by the user, the user simply does not (cannot perform charging). Not only can you know, but you can also know how long you can wait to get charged in that charging menu. Therefore, user convenience can be further enhanced.

  The invention according to claim 11 is the charging power supply system according to claim 10, and is selected after the elapse of the waiting time when it is determined that the request response availability determination unit cannot execute the request. Reservation accepting means for accepting a reservation for performing charging using the charging menu is provided.

  According to the charging power supply system according to claim 11 configured as described above, when the user cannot immediately perform charging using the charging menu selected by the user, the user makes a reservation and sets the reserved time (waiting time). The right to execute the charging after the elapse of time can be secured. Therefore, user convenience can be further enhanced.

  On the other hand, in addition to the configuration for determining whether or not execution is possible when there is a new charge request as described above, for example, as described in claims 12 to 15, whether or not there is a new charge request. It is also possible to take a configuration that appropriately determines and outputs whether or not charging is possible.

  First, the invention described in claim 12 is a charging power supply system according to any one of claims 2 to 6, which is newly based on the number of power supply means that are not supplying power. Menu-specific execution feasibility judgment means for judging at least one of an executable charge menu and a new non-executable charge menu, and menu-specific execution feasibility information indicating a part or all of the judgment result by the menu execution feasibility judgment means And a menu-specific executability information output means for outputting.

  According to the charging power supply system according to claim 12 configured as described above, which charging menu can be executed by the user who is going to newly charge, or which charging menu is immediately executed. It is possible to know information such as whether or not to perform charging, and it is possible to appropriately determine whether or not to execute charging according to the information. Therefore, user convenience can be further enhanced.

  Which of the executable charging menu and the non-executable charging menu is output can be considered as appropriate. For example, as described in claim 13, the menu-specific execution determination unit determines at least an executable charging menu. The menu-specific executability information output means may output information indicating at least an executable charge menu as the menu-specific executability information.

  Further, for example, as described in claim 14, the menu-specific executability determination unit determines at least a non-executable charge menu, and the menu-specific executability information output unit at least cannot execute as the menu-specific executability information. Information indicating a charging menu may be output. Of course, both an executable charging menu and an inexecutable charging menu may be output.

  And when it is comprised so that the information which shows the non-executable charge menu like Claim 14 may be output, the required time until the charge is completed for each charge currently performed further is required A waiting time predicting means for predicting a waiting time until charging is possible in an inexecutable charging menu based on each required time predicted by the required time predicting means, and the waiting time predicting means And waiting time information output means for outputting waiting time information indicating the waiting time predicted by.

  With this configuration, as in the case of claim 10 described above, it is possible to know how long to wait for a charge menu that cannot be immediately executed at the current time, and to further improve user convenience.

  Furthermore, when the waiting time information is configured to be output in this way, it is preferable to provide a reservation receiving unit as described in claim 15. That is, the reservation accepting unit accepts a reservation for performing charging by the charge menu after the waiting time elapses when the non-executable charging menu is determined by the menu executable determination unit.

  By configuring in this way, as in the case of claim 11 above, it is possible to make a reservation for a charging menu that cannot be executed immediately at the present time, so that convenience for the user can be further enhanced.

  And when the reservation reception means is provided as in the charging power supply system according to claim 11 or claim 15, the waiting time prediction means takes into account the reservation amount as described in claim 16. It is better to predict the waiting time. Specifically, when the reservation is accepted by the reservation accepting means, the waiting time predicting means predicts the time required for charging by the reserved charging menu, and performs charging by the reserved charging menu. The waiting time is predicted during the period from the scheduled start time until the estimated required time elapses, considering that charging is performed in the charging menu.

  According to the charging power supply system according to claim 16, configured as described above, if there is a reservation, the reservation is also considered (that is, the reserved time zone is at least the number necessary for the reserved charging). The user can know the waiting time more accurately because the waiting time is predicted (in consideration of the fact that the power supply means cannot be used).

  The charging power supply system according to any one of claims 2 to 16 described above is more preferably provided with a charging fee calculation unit as described in claim 17. . The charging fee calculating means calculates a charging fee for the charging according to a preset calculation criterion when the vehicle is charged from the charging power output terminal by the charging control means.

  There are various ways of setting the calculation standard. For example, as described in claim 18, it can be set individually for each charging menu. By doing so, for example, a charge menu with a larger maximum power (that is, a larger number of supply sources) can be charged more, and the charge charge is calculated appropriately according to the charge menu. Can do.

  In this case, if the power supply from the service supply means is configured to be received as described in claim 5 above, how the charge received from the service supply means is used as the charging fee. However, as an example, regardless of whether or not the service is supplied from the service supply means, the charge is based on the charge menu selected at the start of charging (when charging is requested) (charging) (A charge based on a calculation standard corresponding to the menu). In this way, the user who has been able to receive the supply from the service supply means has a better profitability and can satisfy the user more.

  Various methods for calculating the charging charge based on the calculation standard are also conceivable. For example, a metered system based on the amount of electric power can be adopted as described in claim 19. That is, for each of a plurality of charge power output terminals, when the vehicle is charged from the charge power output terminal by the charge control means, the power amount detection for detecting the power amount output to the vehicle to be charged And a charging fee calculation unit calculates a charging fee based on the amount of power detected by the power amount detection unit and a calculation criterion.

  In this way, charging is made according to the amount of power supplied to the vehicle, and if the calculation standard is set for each charging menu, the charge calculation according to the amount of power is basically performed. In addition, since the final charging fee is calculated in consideration of the calculation standard corresponding to the charging menu, it is possible to calculate and charge an appropriate charging fee.

  And in the case of the structure which calculates the charge charge based on the electric energy and the calculation standard in this way, the calculation standard is as described in claim 20, and the charge menu having a larger maximum outputable power has the same electric energy. It is good that the charging fee is set to be high. In this way, it is possible to calculate and charge a more appropriate charge according to the charge menu.

Preferred embodiments of the present invention will be described below with reference to the drawings.
[First Embodiment]
FIG. 1 shows a schematic configuration of the charging station 1 of the present embodiment. The charging station 1 is for supplying charging power of a storage battery to a vehicle that runs using the power of the storage battery as a drive source. The charging station 1 receives AC power input from a commercial AC power source 2 such as a power company distribution network. The power distributor 3 that distributes 10 and the 10 rectifiers (first rectifier 11 and second rectifier 12 that receive each power distributed by the power distributor 3 and convert it into DC power) , Third rectifier 13,..., Tenth rectifier 20) and ten output terminals (first output terminal 31, second output terminal 32, third output terminal) for outputting charging power to the vehicle. 33,..., A tenth output terminal 40), and a switch 4 that switches the output destination of the electric power from each of the rectifiers 11 to 20 as appropriate (details will be described later) and outputs from any one of the output terminals. 4 outputs 10 charging stations (first charging station 51, second charging station 52, third charging station 53,...) Provided for each of these output terminals to charge the vehicle with the charging power output from the children 31 to 40. .. 10 charging state monitors provided for each of these output terminals in order to monitor the charging state of the vehicle (storage battery) charged by the charging power from the 10th charging stand 60) and each output terminal 31-40 (First charge state monitor 41, second charge state monitor 42, third charge state monitor 43,..., Tenth charge state monitor 50) and various operations of the entire charging station 1 are controlled. And a main operation panel 6 for displaying an operation state of the charging station 1 as a whole and for performing various setting operations by an administrator or the like.

  Each charging stand 51-60 is provided with a charging plug (first charging plug 61, second charging plug 62, third charging plug 63,..., 70) for connecting to a vehicle to be charged. The charging power output from the output terminals 31 to 40 of the switching device 4 (charging power for the charging stations 51 to 60) is output from the corresponding charging plug to the vehicle via the corresponding charging state monitor. . And the storage battery of a vehicle is charged with the charging electric power output from each charging plug 61-70.

  The charging station 1 of the present embodiment can input a maximum of 100 kW of electric power from the commercial AC power supply 2 by contract with an electric power company. Therefore, the power of 100 kW is divided into 10 by the power distributor 3 and input to the rectifiers 11 to 20.

  Each of the rectifiers 11 to 20 converts input AC power into charging DC power, and has a maximum output capacity of 10 kW DC power (charging power). In other words, 100 kW AC power is distributed into 10 parts, and each of these is input to 10 kW output rectifiers, respectively, so that 10 kW DC power can be individually supplied from each rectifier 11 to 20. Yes.

  The switch 4 is input to input terminals (first input terminal 21, second input terminal 22, third input terminal 23,..., Tenth input terminal 30) to which power from each of the rectifiers 11 to 20 corresponds. The output destination of each input power is individually switched to any one of the output terminals 31 to 40. This switching is performed according to the SW control signal output from the switch (SW) control signal output unit 5c of the control device 5.

Thereby, input electric power from one or a plurality of rectifiers can be collectively (combined) and output as charging electric power from any one of the output terminals.
In the charging station 1 of the present embodiment, three types of charging menus of quick charging, medium speed charging, and low speed charging are set according to the maximum power supplied during charging and can be selected by the user.

  Among these, quick charging is a charging menu that can be charged in a short time (for example, about 30 minutes) by supplying charging power of up to 50 kW using electric power from five rectifiers, and is slow charging Is a charging menu that can be charged for a long time (several hours) by supplying charging power of up to 10 kW using the power from one rectifying device. It is possible to perform charging in a shorter time (for example, about 1 to 2 hours) than low-speed charging, although it takes longer than rapid charging by supplying charging power of up to 30 kW using the power from the rectifier Charging menu.

  Therefore, for example, when the quick charging is selected in the first charging stand 51, the switching device 4 is any five of the unused (empty) rectifiers that are not supplying power to any charging stand ( For example, by switching all the output destinations of the charging power from the first to fifth rectifiers 11 to 15 to the first output terminal 31, the charging power for five rectifiers (maximum 50 kW) is output to the first charging stand 51. To do. Further, for example, when the low-speed charging is selected at the third charging stand 53, the switch 4 outputs the charging power output from any one of the unused rectifiers (for example, the tenth rectifier 20). Is switched to the third output terminal 33 to output charging power for one rectifier (maximum 10 kW) to the third charging stand 53. The same procedure applies when medium speed charging is selected.

  FIG. 2 shows the internal configuration of the switch 4. Inside the switch 4, for each one of the input terminals 21 to 30 to which power from the rectifiers 11 to 20 is input, the power supply that connects the input terminal and the ten output terminals 31 to 40. The line is connected. Each of these power supply lines is provided with switches SW101, SW102,..., SW1010 for conducting / cutting off the power supply lines. It is controlled by the SW control signal from 5c.

  For example, for the first rectifier 11, switches SW101, SW102, SW103,... SW110 are provided for each power supply line connecting the first rectifier 11 and the output terminals 31 to 40, respectively. When, for example, the switch SW103 connected to the third output terminal 33 is turned on among these ten switches, the input power from the first rectifier 11 is switched to the third output terminal via the turned on switch SW103. 33 and supplied to the third charging stand 53.

  Therefore, for example, when medium-speed charging is selected at the second charging stand 52, if three of the first to third rectifiers 11 to 13 are in an unused state, the power from these three units is used. The switch SW102 on the power supply line connecting the first input terminal 21 and the second output terminal 32 and the switch SW202 on the power supply line connecting the second input terminal 22 and the second output terminal 32 to output from the second output terminal 32. Then, the switches SW302 on the power supply line connecting the third input terminal 23 and the second output terminal 32 are turned on. As a result, charging power for a total of three units (maximum 30 kW) of the first to third rectifiers 11 to 13 is output from the second output terminal and supplied to the second charging stand 52.

  2, the last two digits (hereinafter also referred to as “n”) of the numbers in the symbols of the switches SW101, SW102,... The remaining one digit (or two digits) (hereinafter also referred to as “m”) corresponds to the prefix number (first to tenth) of the name of the rectifier to be input. That is, the switch SWmn indicates that the charging power from the m-th rectifier is output from the n-th output terminal. For example, the “switch SW302” outputs the charging power from the third rectifier 13 to the second output. This is a switch for outputting from the terminal 32.

  Further, the SW control signal output unit 5c that generates and outputs the SW control signal is provided with an interlock unit 5d (see FIG. 3) so that the power of the same rectifier is not output from a plurality of output terminals. Thereby, for example, two or more of the ten switches SW101, SW102,..., SW110 connected to the first rectifier 11 are prevented from being turned on simultaneously. The configuration of the interlock unit 5d shown in FIG. 3 will be described later.

  The ten charging state monitors 41 to 50 each have an amount of electricity related to the charging power output to the corresponding charging station, that is, various amounts of electricity related to the charging state of the storage battery in the vehicle to be charged (charging power, voltage, current, etc.). Is output to the control device 5.

  Each charging stand 51-60 has a stand operation panel (first stand operation panel 71, second stand operation panel 72, third stand operation panel 73,..., Which plays a role of an interface between the charging station 1 and the user. .. A tenth stand operation panel 80) is provided. Since each of the stand operation panels 71 to 80 has the same configuration, the first stand operation panel 71 of the first charging stand 51 will be described as a representative.

  The first stand operation panel 71 receives a stand monitor 71a for displaying various information such as a charging menu and a charging status for a user or the like who wants to charge at the first charging stand 51, and accepts various operation inputs by the user or the like. Stand operation unit 71b, stand speaker 71c for outputting various information such as various guides, operation guides, and charging statuses to the user, etc., and a cash input slot and various cards (for the user to settle the charging fee) A credit card, a prepaid card or the like) and a payment account 71d.

  The information displayed on the stand monitor 71a includes, for example, an initial menu screen (see FIG. 4) displayed at a charging station where charging is not performed, and a charging status screen (see FIG. 4) displayed at a charging station where charging is performed ( 5), a settlement screen (see FIG. 6) displayed when charging is completed at the charging station being charged.

  The stand monitor 71a also has a touch panel function. For example, when the initial menu screen shown in FIG. 4 is displayed, the “fast”, “medium speed”, and “low speed” displayed as the charge menu are displayed. By touching (selecting) any of the display surfaces, a new charge start request is accepted, and it is accepted that the touched charge menu has been selected.

  In addition, when the charging in the selected charging menu cannot be performed immediately due to an insufficient number of unused rectifiers or the like, a reselection screen shown in FIG. Reservations can also be accepted. When the user wishes to make a reservation, a user information input screen shown in FIG. 12B and a registration end notification screen shown in FIG. 12C are also displayed.

  The main operation panel 6 includes a main monitor 6a for displaying various information (see FIG. 7) regarding the operation state of the charging station 1 as a whole, such as the states of the charging stations 51 to 60 and reservation status, and various setting operations by an administrator or the like. And a main operation unit 6b for receiving, and the like.

  The control device 5 includes a control unit 5a that controls various controls of the entire charging station 1, a memory 5b that stores various control programs and setting data, and a SW control signal output unit 5c that outputs a SW control signal to the switch 4. Etc.

  The control unit 5a includes an arithmetic processing unit such as a CPU, and executes various control processes (including the charge control process of FIG. 9 to be described later) according to various control programs stored in the memory 5b. Input / output of various data / information to / from 60 stand operation panels 71-80, input / output of various data / information to / from main operation panel 6, and acquisition of various information from each charge state monitor 41-50 The control of each rectifier 11 to 20 (control of charging power), the switching control of the switch 4 and the like are performed.

  The SW control signal output unit 5c outputs the SW control signal Pmn (P101, P102...) Individually for each switch to each switch (see FIG. 2) of the switch 4 in accordance with a command from the control unit 5a. (Refer to FIG. 3A described later). Note that “m” and “n” here correspond to “m” and “n” in the symbol SWmn of each switch described above. That is, the SW control signal Pmn is a SW control signal for controlling the switch SWmn in the switch 4. For example, the “SW control signal P302” is the charge power from the third rectifying device 13 and the second output terminal 32. Is to control the switch SW302 for outputting from.

  In this embodiment, the SW control signal Pmn is a binary signal of H level or L level, and the switch SWmn corresponding to the case where the SW control signal Pmn is H level is configured to be turned on.

  Further, the SW control signal output unit 5c includes the interlock unit 5d as described above. More specifically, as shown in FIG. 3A, each SW control signal Pmn is output via the interlock unit 5d in the SW control signal output unit 5c.

  In the SW control signal output unit 5c, as shown in FIG. 3A, the basic control signal Pomn (Po101, Po102...) That is the original of the SW control signal Pmn that is finally output to the switch SWmn. Is generated based on a command from the control unit 5a. The basic control signal Pomn can directly control the corresponding switch SWmn by itself, and therefore, the basic control signal Pomn may be output to the corresponding switch SWmn as it is.

  However, if a plurality of switches connected to the same rectifying device are simultaneously turned on for some reason such as a malfunction of the control unit 5a, the charging power from the same rectifying device is distributed to a plurality of output terminals and output. (As a result, it is distributed and supplied to a plurality of vehicles).

  Therefore, in this embodiment, the basic control signal Pomn is not output as it is, but is output via the interlock unit 5d so that charging power is not output from the same rectifier to a plurality of output terminals. . Specifically, the interlock unit 5d is configured by a plurality of interlock circuits individually provided for each basic control signal Pomn (that is, for each SW control signal Pmn).

  As an example, FIG. 3B shows an interlock circuit provided for the SW control signal P101 for controlling the switch SW101 for outputting the power of the first rectifier 11 from the first output terminal 31.

  The interlock circuit shown in FIG. 3B has each basic corresponding to each SW control signal Pmn output to the ten switches SW101, SW102, SW103,..., SW110 connected to the first rectifier 11. Of the control signal Pomn, an OR gate 91 to which other basic control signals Po102, Po103,..., Po110 other than the basic control signal Po101 corresponding to the SW control signal P101 to be output is input, and this OR gate 91 And an AND gate 93 to which the basic control signal Po101 corresponding to the output SW control signal P101 and the output signal of the inverter 92 are input. Then, an output signal from the AND gate 93 is output to the corresponding switch SW101 as the SW control signal P101.

  With such a configuration, for example, when the corresponding switch SW101 is turned on, the basic control signal Po101 becomes H level by a command from the control unit 5a. At this time, the control unit 5a causes the power from the first rectifying device 11 to be output from the first output terminal 31 via the switch SW101 (in other words, other output via other switches other than the switch SW101). The other basic control signals Po102, Po103,..., Po110 other than the basic control signal Po101 are controlled so as to be at the L level. Therefore, the output from the OR gate 91 becomes L level, the output from the inverter 92 becomes H level, and is input to the AND gate 93, whereby the output from the AND gate 93 is the basic control signal Po101 corresponding to the output target. Will depend on.

  On the other hand, for some reason such as a malfunction of the control unit 5a, any one of the other basic control signals Po102, Po103,. However, in the case where the H level reaches other basic control signals as described above, the output from the OR gate 91 becomes the H level, and the output from the inverter 92 becomes the L level. For this reason, the output from the AND gate 93 becomes L level regardless of the basic control signal Po101 corresponding to the output target, thereby corresponding to the corresponding switch SW101 and the basic control signal erroneously set to H level. None of the switches are turned on.

  For each of the other SW control signals, an interlock circuit as shown in FIG. 3B is provided for each SW control signal, and each SW control signal is output from the interlock circuit. Note that the interlock circuit shown in FIG. 3 is merely an example, and other circuit configurations may be used.

  The control part 5a displays the initial menu screen shown in FIG. 4 with respect to the stand monitor of the charging stand which is not charged among each stand monitor 71a-80a of each charging stand 51-60. In this initial menu screen, three types of charging menus, an expected charging time (required time), a charge surplus coefficient K, availability information, and an expected waiting time for each charging menu are displayed.

The expected charging time displayed on the initial menu screen is an approximate charging time expected based on the standard (average) secondary battery capacity of the vehicle.
In addition, as the availability information, “permitted” or “impossible” is displayed for each charging menu. Based on the number of rectifiers in the unused state, the control unit 5a determines whether it can be executed immediately (newly) or not for each charging menu, and the result of the determination is “permitted”. ”Or“ impossible ”.

  For example, when 6 rectifiers are already used for charging, there are 4 unused rectifiers, so “not possible” for quick charging that requires 5 units, other medium speed charging and “Low” for low speed charging. The display example of FIG. 4 is a display example in the case where such a medium-speed charge and a low-speed charge that can be performed quickly are possible.

  The expected waiting time is an estimated value of the time required for each charging menu to start charging according to the charging menu. Of course, the expected waiting time is 0 minutes for a charge menu that can be executed immediately at the moment, but for a charge menu that cannot be executed immediately at the present time, the charge menu of the charge menu that is currently being executed is displayed. The time until the space for the number of rectifiers necessary for execution can be secured is predicted and displayed as a waiting time. The display example of FIG. 4 shows that it is expected that five or more rectifiers will be available and ready for quick charging after 30 minutes.

  The control unit 5a, for each charging station, is charged for each charging station based on the information from the corresponding charging state monitor, and the time required until charging at that charging station is completed at a certain period. Predict.

  In the present embodiment, the control unit 5a controls the rectifiers 11 to 20 to perform charging. As a specific charging method, the well-known constant current constant voltage (CVCC: Constant Voltage Constant Current) is used. ) Method is used. Of course, charging in this manner is merely an example.

  In CVCC charging, as shown in FIG. 8A, charging is performed at a constant current Ia after the start of charging, and the charging voltage gradually increases during that time. Then, after charging to a predetermined voltage value Va, switching to constant voltage charging is performed. After switching to constant voltage charging, the charging current gradually decreases. That is, as charging progresses, the power required for charging substantially decreases.

  In addition, there is a correlation as shown in FIG. 8B between the storage battery voltage (charge voltage) and the discharge capacity. If the storage battery voltage is known, the discharge capacity from the storage battery can be roughly estimated, Therefore, the state of charge (SOC) of the storage battery can be predicted.

  Therefore, the control unit 5a, as shown in FIG. 8 (a) or FIG. 8 (b), is based on information such as the charging voltage and charging current from the charging state monitor corresponding to the charging station where charging is performed. Utilizing various characteristics, the SOC of the storage battery being charged, the expected required time (including the expected end time) until charging of the storage battery, and the like are calculated.

  Note that it can be appropriately set as to what is determined to be the end of charging. For example, the charging may be ended when the battery is fully charged, or the battery is charged to a predetermined charging rate (for example, 80%). In some cases, charging may be terminated.

  In this way, for a charging station that is being charged, the required time until charging at the charging station is completed is predicted. Therefore, based on the number of rectifiers in the unused state and the estimated required time predicted for the charging that is already being performed, the control unit 5a performs a determination of whether or not a new charge is possible, an estimated waiting time, etc. The result is displayed on the initial menu screen.

  If a reservation has been registered, the control unit 5a determines whether or not a new charge is possible, predicts an expected waiting time, and the like in consideration of the reservation. That is, the time required for charging by the reserved charging menu (expected charging time) is predicted, and the charging is performed during the period from the scheduled start time of charging by the reserved charging menu until the estimated required time elapses. The waiting time is predicted in consideration of the charging on the menu.

  The charge surplus coefficient K indicates a charge surplus rate for each charging menu with respect to the basic charge. In the present embodiment, a basic charge per unit power amount (1 kWh) is determined in advance. This basic charge is a fixed charge regardless of the charging menu. In addition, the charge amount calculation method basically uses a pay-as-you-go system according to the amount of power charged, and the amount obtained by multiplying the amount of power charged by the basic charge is the basic charge. It becomes a charge.

  Then, the basic charge charge is further multiplied by a charge surplus coefficient K set for each charge menu, thereby calculating a charge charge finally charged to the user. The charge surplus coefficient K is set so that the charge menu for the same amount of power increases as the charge menu with the maximum output power increases. Specifically, as shown in FIG. K = 1.2, medium speed charging is K = 1.1, and low speed charging is K = 1.0.

  That is, in the case of low-speed charging, the amount obtained by multiplying the charging power amount by the basic charge becomes the final charging charge as it is. And even if the charging power is the same, if charging with medium speed charging, the charge will be higher than if charging at low speed, and if charging with quick charging, it will be even higher than if charging at medium speed .

  Each charging state monitor 41 to 50 is provided with a watt hour meter for measuring the charging power, and the measurement result by the watt hour meter together with other information such as a charging voltage and a charging current. Input to the control device 5. Therefore, the control part 5a can know the charged electric energy based on the measured value of the inputted electric energy.

  A user who has come to the charging station 1 to charge the vehicle stops the vehicle at an empty charging stand and performs various operations for charging according to the display screen of the stand monitor. In this case, since the initial menu screen of FIG. 4 is normally displayed, the user looks at the content displayed on the initial menu screen and selects a desired one of “rapid”, “medium speed”, or “low speed”. Touch the display part of the charge menu to select the charge menu and request a new charge start.

  At this time, when a charge menu whose use permission information is “permitted” is selected, on the basis of the selected content, various kinds for the control unit 5a to perform charging by the selected charge menu at the charging station. Take control.

  Specifically, out of the unused rectifiers, the number of rectifiers necessary for the output of the charging power corresponding to the charging menu is used as the supply source, and the output corresponding to the power output destination from the supply source The switch 4 is controlled so as to switch to a terminal, and the power supplied from each rectifier as a supply source is controlled to control charging at the charging station.

  Of course, if there are just the required number of unused rectifiers, all of the unused rectifiers will be suppliers, but if more than the required number of rectifiers are available, from among them Select the required number of rectifiers as appropriate (for example, by establishing selection criteria in advance).

  After charging is started, a charging status screen shown in FIG. 5 is displayed. On this charging status screen, a charging menu for charging that is currently being performed, a charging start time, an elapsed time since the start of charging, an estimated required time until the end of charging, etc. are displayed.

  When the charging is completed, a settlement screen shown in FIG. 6 is displayed. In this checkout screen, the charge menu of the completed charge, the unit price of the charge, the charge surcharge rate (same as the charge surcharge coefficient K described above), the charge amount, the time taken for the charge, the charge charge, the checkout method selection menu, Etc. are displayed. The method for calculating the charge is as described above.

  When this settlement screen is displayed, the user selects a desired settlement method. That is, by touching the display portion of the desired settlement method in the displayed settlement method selection menu ("cash", "prepaid card", "credit card" ... in FIG. 6), the settlement method is displayed. The selection is accepted. For example, if “cash” is selected, cash is inserted into the cash input portion (not shown) of the checkout port of the stand operation panel. For example, if “credit card” is selected, the credit of the checkout port of the stand operation panel is selected. Payment can be completed by inserting a credit card into a card insertion section (not shown). After completion of payment, the initial menu screen shown in FIG. 4 is displayed again.

  On the other hand, when a charge menu whose use availability information is “impossible” is selected, a charge disapproval display indicating that charging cannot be performed in the charge menu immediately is performed. Then, based on the state of the entire charging station 1 at that time, a reselection screen for prompting the user to reselect as shown in FIG.

  In this reselection screen, the same information as the initial menu screen shown in FIG. 4 (however, the latest information) is displayed based on the current state of the entire charging station 1, and “ "End" display section, a message prompting you to select the charging menu again, a message informing you that you will go to the reservation registration screen if you select an unavailable charging menu, and an "end" display section if you want to end A message that prompts the user to select (touch) is also displayed.

  When an available charging menu is selected on this reselection screen, charging is performed in the same procedure as when an available charging menu is selected on the initial menu screen of FIG. Further, when the user who does not desire further operation selects “END”, the screen returns to the initial menu screen of FIG. 4 again.

  On the other hand, if an unavailable charging menu is selected again, a reservation is made for charging the selected charging menu (a charging menu that cannot be executed at this time) using the charging menu after the waiting time has elapsed. Proceed to the reservation registration screen to accept.

  Specifically, first, the user information input screen shown in FIG. 12B is displayed to prompt the user information to be input. In this example, the user is prompted to enter an arbitrary 4-digit password as user information. A user who wishes to make a reservation inputs a password by touching the displayed number or by operating a number key (details are not shown) of the stand operation unit. Then, when the display portion displayed as “confirmed” is touched after the input, the input of the personal identification number is accepted, and the reservation is accepted. Then, after the registration completion notification screen shown in FIG. 12C is displayed for a predetermined time, the screen returns to the initial menu screen of FIG.

  The control unit 5 a also displays the state of each charging station 51 to 60, the reservation registration status, and the like on the main operation unit 6 b of the main operation panel 6. Specifically, as shown in FIG. 7, the status for each charging station (state of whether charging or not charging (empty vehicle), etc.), the same information as the charging status screen shown in FIG. Information related to reservations registered in the whole (reservation registration list) and the like are displayed.

  Next, the charging control process executed by the control unit 5a of the present embodiment will be described using the flowchart of FIG. When the charging control process is started, the control unit 5a first checks the usage status of the entire charging station 1 in S110. Specifically, whether or not each charging station 51 to 60 is used, the charging status of each charging station being charged, the prediction of the charging end time (predicted required time), the understanding of the unused rectifier and its Various status confirmations such as the total number (free number) N, reservation status (presence / absence of reservation registration), etc. are performed, and based on these, various information including the information shown in FIGS. .

  Based on the result, monitor display output is performed in S120. That is, the charging status screen shown in FIG. 5 is displayed on the stand monitor of the charging station that is being charged, and the initial menu screen shown in FIG. 4 is displayed on the stand monitor of the charging station that is not being charged. The screen shown in FIG. 7 is displayed on the main monitor 6a of the main operation panel 6.

  Then, in S130, it is determined whether or not a charge reservation registration has already been made. This reservation registration is performed in a reservation reception process (S420 in FIG. 10; FIG. 11 in detail) in the new charge start request reception process in S150 described later. When reservation registration is not made (S130: NO), it progresses to S140 and it is judged whether the new charge start request | requirement was made in either of each charging stand 51-60. More specifically, it is determined whether any charging menu is selected on the initial menu screen of FIG. 4 displayed on the stand monitor of the charging station where charging is not performed.

  If there is no new charge start request (S140: NO), it is determined in S160 whether there is a charging station that has already been charged. If there is no charging station that is being charged, the process returns to S110. If there is a charging station in the middle (S160: YES), the process proceeds to S170, and it is determined whether there is a charging station that is nearing the end of charging. This determination is made by appropriately determining a determination criterion, for example, whether or not the expected required time to completion (see FIG. 5) has become a predetermined time or less (for example, 10 minutes or less).

  In FIG. 9, there is a process of S800 between S160 and S170. This process of S800 is a process performed in the second and third embodiments described later, and is performed in the present embodiment. Absent.

  If it is determined in S170 that there is no charging station that is nearing the end, the process returns to S110. If it is determined that there is a charging station that is nearing the end (S170: YES), an end notice is notified in S180. Output. Both the notice of completion notice and the notice of completion of S210, which will be described later, are performed by sound output using a stand speaker of a corresponding charging station, a main speaker (not shown) that can be announced to the entire charging station 1, and the like. Of course, the notification by voice output is merely an example, and the user may be notified by other methods. As another method, for example, a method of notifying a user's mobile phone of an email can be considered.

  After the completion notice notification is output, the process proceeds to S190, and it is determined whether or not charging is completed at any charging station. If there is no charging station that has been charged, the process returns to S110. However, if the charging is completed at any of the charging stations that are being charged (S190: YES), in S200, Then, power output from the rectifier (Ja rectifiers) that has supplied the charging power is stopped.

  Then, in S210, an end notification is output, and in subsequent S220, the vacant number of rectifiers detected at present (the number of unused rectifiers) N, that is, the vacant number N detected in S110, The vacant number N is updated by adding the number Ja of the rectifiers that have become unused due to the output being stopped in S200.

  In step S230, the charging fee for the completed charging is calculated. As described above, this calculation is performed by multiplying the basic charge by the amount of charging power and further multiplying by the charge surplus coefficient K. Thereafter, in S240, the settlement screen (see FIG. 6) including the calculated charging fee is displayed on the stand monitor to prompt the user to pay the fee, and when the settlement is completed (S250: YES), the process returns to S110 again. .

  On the other hand, in the determination process of S130, when it is determined that the reservation registration has already been performed (S130: YES), the process proceeds to S260, and whether or not the reservation time has exceeded a predetermined time for each of the registered reservations. Judge.

  If there is no reservation registration that exceeds the reservation time for a predetermined time, the process proceeds to S140, but if there is even one reservation registration that exceeds the reservation time for a predetermined time (S260: YES), the process proceeds to S270 and the reservation is made. After canceling the user's reservation registration, the process proceeds to S140.

  On the other hand, if it is determined that a new charge start request is made in the determination process of S140 due to the touch (selection) of any charge menu on the initial menu screen (see FIG. 4) (S140: YES), S150 Proceed to, and new charge start request acceptance processing is executed. Details of the new charge start request acceptance process are shown in FIG.

  When this new charging start request acceptance process is started, first, in S310, a screen (not shown) for prompting confirmation of whether or not the user is a reservation user who has made a reservation registration is displayed, and whether or not the user is a reservation user. Require confirmation input. For example, a method of displaying “reserved registered user” and “new user” and selecting one of them can be considered.

  In S320, it is determined whether or not the user is a reserved user based on the input contents of the user. If the user is not a reserved user, the process proceeds to S330 and the requested charging menu (that is, the charging selected on the initial menu screen in FIG. 4). Menu). Then, in subsequent S340, it is determined whether or not the charging in the charging menu can be immediately executed. This determination is not made by considering only the number N of rectifiers that are actually vacant at the present time. If reservation registration has already been made, the reservation registration is prioritized during the reservation registration period. Judgment is also taken into account.

  And when it is judged that charging can be performed immediately (S340: YES), the rectifier securing process of S350 is performed. That is, in order to use the number of rectifiers corresponding to the charging menu (Jb units) for charging in the charging menu, the Jb rectifier units are secured and are detected at the present time. The free number N is updated by subtracting the reserved number Jb from the free number N of rectifiers.

  In step S360, an instruction is given to connect the charging plug to the vehicle, and after confirming that the charging plug is connected (S370: YES), the charging time is predicted based on the voltage of the storage battery of the connected vehicle. Are displayed (S380). In S390, the switch 4 is controlled so that the electric power from the Jb rectifiers required for charging is output to the corresponding charging stand, and in S400, the Jb rectifiers are charged. Starts charging the vehicle (outputting charging power). After the charging is started, the charging status screen shown in FIG. 5 is displayed on the stand monitor of the charging station where the charging is started.

  On the other hand, if it is determined in S340 that it cannot be executed immediately (S340: NO), the process proceeds to S410, a charge disabling display is performed on the stand monitor, and the process proceeds to the reservation acceptance process in S420.

  If it is determined in S320 that the user is a reserved user (S320: YES), the process proceeds to S430 to instruct to input user information. This user information is the password described with reference to FIG. 12B, and is input in the processes of S670 to S680 in the reservation receiving process of FIG. 11 described later.

  In step S440, the input user information is compared with the user information already registered for reservation, and it is determined whether the input user information is registered for reservation. Here, if the user information is not registered for reservation (S440: NO), “No reservation registration” is displayed in S490, and this new charge start request acceptance process is terminated. (S440: YES), in subsequent S450, it is determined whether or not the reservation registration is canceled.

  As shown in S260 to S270 of FIG. 9, when a reservation is registered but the reservation time exceeds a predetermined time, the reservation is canceled. Therefore, it is determined whether or not the reservation registration has been canceled in S450. If the reservation registration has been canceled (S450: YES), an indication “cancel” is displayed in S500. To complete the new charge start request acceptance process. On the other hand, if the reservation registration has not been canceled (S450: NO), it is determined in S460 whether or not the reservation time has arrived. Until the reservation time arrives, the message “Please wait” is displayed in S480 and the user is put on standby. If the reservation time has arrived (S460: YES), in S470, after confirming that the number of rectifiers required for charging (Jb units) is free (S470: YES), S350 Proceed to the rectifier securing process.

  Next, the reservation acceptance process in S420 will be described with reference to FIG. When the reservation acceptance process is started, first, in S610, the usage status of the entire charging station 1 is confirmed again. This confirmation is basically the same as S110 in FIG.

  In S620, an expected waiting time until charging can be started with a charging menu as requested by the user is calculated. Further, in S630, for each of the charging menus other than the charging menu requested by the user, charging availability (usability) and expected waiting time are calculated. Based on the results calculated in S620 and S630, a reselection screen (see FIG. 12A) for prompting reselection of the charging menu is displayed in S640.

  If it is determined in S650 whether the charging menu of “rapid”, “medium speed”, or “low speed” is selected or “end” is selected, and “end” is selected However, if any of the charge menus is selected, the process proceeds to S660, where it is determined whether or not the charging by the selected charge menu can be started immediately.

  Here, if charging can be started immediately by selecting a charging menu whose availability information is “available” (S660: YES), the process proceeds to the rectifier securing process of S350 (FIG. 10). If the charging cannot be started immediately because the charging menu whose information is “impossible” is selected (S660: NO), the user is instructed to input user information in S670. Specifically, the user information input screen shown in FIG. 12B is displayed, and input of user information (password) is awaited. When user information is input (S680: YES), reservation registration is performed in S690.

  Specifically, the reservation registration in S690 is performed after the estimated waiting time for the selected charging menu has elapsed, until the estimated charging time required for charging the charging menu elapses from the reserved time. A reservation for performing charging using the required number (Jb) of rectifiers according to the charging menu is accepted. As a result, for the reserved period, Jb rectifiers are reserved for charging the reservation target. Further, a registration end notification screen shown in FIG.

  As described above, the charging station 1 according to the present embodiment includes a plurality of rectifiers (10 in this example) that can supply charging power. Is not fixed so that the charging power is supplied, but the switching device 4 supplies the power from one or more rectifiers to one vehicle (one charging station) according to the charging menu. Can be supplied.

  Therefore, as long as there are unused rectifiers other than the rectifiers that are already used for charging, charging can be performed at the charge menu desired by the user within the number of the rectifiers. As a result, it is possible to construct and provide the charging station 1 having a high operating rate as a whole, while suppressing the complexity, size and cost increase of the facility scale.

  In addition, three types of quick charge, medium speed charge, and low speed charge are set as the charge menu, and a desired charge menu can be selected at all 10 charging stations 51 to 60 (unused) As long as the number of rectifiers can handle this). Therefore, the charging station 1 that is highly convenient for the user is realized.

  Each charging stand 51-60 is provided with a stand operation panel 71-80, and the required time for each charging menu, the current availability of the charging menu, the waiting time for the charging menu that cannot be charged immediately, and each charging menu. Various information useful for the user is displayed, such as the charging system (charge premium coefficient K in this example), the charging progress status after the start of charging, the estimated required time until the end, the charging power amount and the charging fee. Further, by operating each of the stand operation panels 71 to 80, various input operations such as selection of a charging menu, charging start request, reservation registration, and settlement method selection can be performed.

Therefore, it is possible to construct and provide a highly convenient charging station that allows the user who has come to the charging station to take various measures depending on the situation at that time.
In addition, when reservation registration is made, the waiting time is also taken into consideration (that is, considering that at least the number of rectifiers necessary for the reserved charging cannot be used in the reserved time zone) Predictions are made. Therefore, the user can know the more accurate waiting time in consideration of the reservation.

  In the charging station 1 of the present embodiment, the charging fee is calculated and charged according to the amount of charging power for each charging stand, and the charging method differs for each charging menu. That is, while a charge-based system according to the amount of electric power is basically set, a charge surplus coefficient K is set for each charging menu, and the larger the amount of electric power required for charging (in other words, the number of rectifiers required for charging becomes smaller). The higher the amount), the higher the charge amount for the same amount of power. For this reason, it is possible to calculate and charge an appropriate charge according to the charge menu.

  In the present embodiment, each of the rectifiers 11 to 20 corresponds to the power supply means of the present invention, the switch 4 corresponds to the switch of the present invention, and each of the output terminals 31 to 40 of the switch 4 is respectively The stand operation panels 71 to 80 correspond to the charging power output terminal of the present invention, the charge request receiving means and the reservation receiving means of the present invention, respectively, and the control device 5 is the charging control means and the charging charge calculating means of the present invention. Each of the charge state monitors 41 to 50 corresponds to a power amount detection unit and a charge state detection unit of the present invention, respectively.

  Further, in the charging control process of FIG. 9, the process of S110 corresponds to the process executed by the menu-specific execution availability determination unit of the present invention, and the process of S120 is the process executed by the menu-specific execution availability information output unit of the present invention. Equivalent to. Further, in the new charge start request acceptance process of FIG. 10, the process of S340 corresponds to the process executed by the request response availability determination means of the present invention, and the process of S410 is the process executed by the charge disable information output means of the present invention. Equivalent to. In the reservation receiving process of FIG. 11, the process of S630 corresponds to the process executed by the other menu executable information output means of the present invention.

[Second Embodiment]
Next, the charging station of 2nd Embodiment is demonstrated. The charging station of this embodiment has the same hardware configuration as the charging station 1 (see FIG. 1) of the first embodiment. Various control processes such as the charge control process (see FIG. 9) executed by the control unit 5a of the charging station are basically the same as those of the charging station 1 of the first embodiment.

  The charging station of this embodiment is different from the charging station 1 of the first embodiment in that the system operation state optimization process of S800 is performed between S160 and S170 in the charging control process shown in FIG. It is.

  As already described, the electric power required for charging decreases as charging progresses (that is, as the SOC of the storage battery increases). Therefore, in this embodiment, at least at the start of charging, charging is started using a regular number of rectifiers corresponding to the selected charging menu, but the number of rectifiers used is originally necessary according to the progress of charging. Focus on the number of cars.

  A specific example of reducing the required number of rectifiers according to the progress of charging will be described with reference to FIG. FIG. 13 shows the change in the number of rectifiers used according to the progress of charging when medium-speed charging is started at the first charging stand 51 and then medium-speed charging is further started at the second charging stand 52. Show.

  As shown in FIG. 13, three rectifiers corresponding to the charging menu (medium speed charging in this example) are used in both charging stations 51 and 52 after the start of charging. Therefore, the total number of rectifiers used by both of these is three after the start of charging by the first charging stand 51 and then six after the start of charging by the second charging stand 52.

  The control unit 5a of the control device 5 predicts and calculates the charging power (predicted charging required power) necessary for charging based on information from the corresponding charging state monitor for each charging stand. The required power decreases as charging progresses as shown in FIG. In the case of medium-speed charging, if the predicted charging required power is lower than 20 kW, only two rectifiers are required. When the charging further progresses and the predicted charging power becomes lower than 10 kW, only one rectifier is required.

  Therefore, after the start of charging, if the number of rectifiers currently in use is greater than the number of units originally required (minimum number required to meet the estimated charging power), use Reduce the number to the number that it originally needed. In the example of FIG. 13, a total of six rectifiers are used at the beginning of charging at the charging stations 51 and 52, but the required power (predicted charging required power) is less than 20 kW as the charging progresses. And 2 units each (4 units in total). Thereafter, when the required power at the second charging station 52 is less than 10 kW, only one rectifier is required for the second charging station 52, and the total is reduced to three. If the electric power required at the first charging stand 51 further falls below 10 kW, only one rectifier is required for the first charging stand 51, and the total is reduced to two.

  FIG. 14 shows details of the system operating state optimization process executed in this embodiment. In the charge control process shown in FIG. 9, if an affirmative determination is made in S160, the process proceeds to S800, and the system operating state optimization process shown in FIG. 14 is executed. When this process is started, first, in S810, the charging state of each charging station that is being charged is confirmed. That is, information necessary for predicting necessary charging power, such as SOC, is acquired for each charging station where charging is performed.

  In step S820, on the basis of the charging state confirmed in step S810, the charging power actually required for the subsequent charging is predicted and calculated for each charging station that is being charged. In subsequent S830, for each charging station that is being charged, the currently supplied charging power (that is, the number of rectifiers currently used) and the required power predicted in S820 (that is, its number) Compare the number of rectifiers required to meet the required charging power).

  Then, in S840, it is determined whether or not there is an excessive charging station using the number of rectifiers based on the comparison result in S830. If there is no excessive charging station used, the system operating state optimization process is performed. When there is an excessive number of charging stations used (S840: YES), the power output from the rectifiers for the excessive number (H) of the charging stations is stopped in S850.

  Further, in S860, the available number N of rectifiers that have been unused due to the output being stopped in S850 is added to the available number N of rectifiers currently detected, thereby updating the available number N.

  According to the charging station of the second embodiment described above, charging is not performed using a regular number of rectifiers corresponding to the charging menu in the entire period from the start to the end of charging, but is required for charging as the charging progresses. As the amount of electric power decreases, the number of rectifiers used for charging is reduced to a number that can satisfy the required electric power. Therefore, the reduced amount can be used for charging other users, and the operating rate of the entire charging station can be further increased.

In the system operating state optimization process of FIG. 14, the process of S820 corresponds to the process executed by the necessary power detection unit of the present invention.
[Third Embodiment]
Next, the charging station according to the third embodiment will be described. The hardware configuration itself of the charging station of this embodiment is the same as that of the charging station 1 (see FIG. 1) of the first embodiment. Further, various control processes such as a charging control process (see FIG. 9) executed by the control unit 5a of the charging station are basically the same as those of the charging station 1 of the first embodiment except for a part.

  The charging station of this embodiment is different from the charging station 1 of the first embodiment in that the system operation state optimization process of S800 is performed between S160 and S170 in the charging control process shown in FIG. , And the contents of the rectifier securing process in S350 in the new charge start request receiving process shown in FIG.

  For example, when a user with sufficient time selects medium-speed charging or low-speed charging in order to reduce the charging fee, charging is performed with the number of rectifiers corresponding to the selected charging menu. Charging is performed by three rectifiers for charging and one rectifier for low-speed charging.

  In this case, if there is another unused rectifier, if charging is also performed using the unused rectifier, the charging can be completed earlier than the time assumed by the user. . If this can be realized, the user will be able to charge the battery while the charging is completed unexpectedly, resulting in a time advantage. By ending earlier, it becomes possible to accept the next new customer early, and there will be merits in terms of equipment operation rate and turnover rate.

  Therefore, in the present embodiment, if the rectifier is free and if it is possible to increase the number of rectifiers for the current charging, the rectifier is free within the range of the increaseable number. The rectifying device is added to the charging power supply source as a service rectifying device.

  However, the charging with the addition of the service rectifier is performed based on the determination on the charging station side in order to effectively use the unused rectifier that is not in use. The calculation of money) does not take into account the use of this service rectifier. That is, the user is charged only according to the charging menu selected by the user. Therefore, for example, even if the user selects low-speed charging, even if there are many free rectifiers and rapid charging is performed with a total of five rectifiers, the charge is only for the low-speed charge selected by the user An additional factor K (K = 1.0) is applied.

  On the other hand, after a certain rectifier starts operation as a service rectifier, a charge request is made by another new user, and if a rectifier operating as a service rectifier is also needed to respond to the request, About a rectifier, the operation | movement as a service rectifier is stopped and it is made to operate | move as one of the charging power supply sources with respect to the new charge request | requirement.

  FIG. 15 shows details of the system operating state optimization process executed in this embodiment. Among the system operation state optimization processes, the processes of S910 to S925 are exactly the same as the processes of S810 to S840 in the system operation state optimization process of the second embodiment shown in FIG. Therefore, description of each process of S910-S925 is abbreviate | omitted.

  If it is determined in the determination process in S925 that there are no excessive charging stations in use (S925: NO), the process proceeds to S950, and whether there is a charging station that is charged with medium-speed charging or low-speed charging. Judge. At this time, if neither medium-speed charging nor low-speed charging is performed (S950: NO), this system operation state optimization processing is terminated, but medium-speed charging or low-speed charging is being executed at any charging station. If so (S950: YES), the process proceeds to S955.

In S955, it is determined whether or not it is possible to increase the charging power at the charging station (that is, the charging station that is being charged by medium-speed charging or low-speed charging).
At this time, for example, in a charging station in which medium-speed charging is selected and executed, if charging is already progressing and the required charging power is less than 30 kW, the number more than the prescribed number (three) In this case, a negative determination is made in S955. On the other hand, if medium speed charging has just started and it is possible to supply, for example, 50 kW of power, the number of units can be increased more than the specified number (3 units), and charging can proceed faster. In this case, an affirmative determination is made in S955, and the process proceeds to S960.

  In S960, it is determined whether or not the rectifier has a space. If there is no space, the system operating state optimization process is terminated. If there is a space (S960: YES), the charging station is in S965. Is set as a service stand and the service flag is set. That is, a flag indicating that the charging station is being charged by more rectifiers than the regular number is set.

  Then, in subsequent S970, among the vacant rectifiers, a predetermined number (U units) of rectifiers that can be increased are used as service rectifiers, so that power from the service rectifiers is supplied to the charging station. The switch of the switch 4 is controlled. And the electric power output from the service rectifier is started.

  On the other hand, if it is determined in the determination process of S925 that there are excessive charging stations in use (S925: YES), the process proceeds to S930, and the rectifiers for the excessive number (H) of charging stations are included. Stop the power output from. However, when the charging station is a service station with a service flag set, that is, when charging power is also supplied from the service rectifier, power output is preferentially stopped from the service rectifier. To do.

  In S935, the available number N of rectifiers that have been unused due to the output being stopped in S930 is added to the currently detected available number N of rectifiers, thereby updating the available number N. However, when the service rectifiers are included in the rectifiers whose output has been stopped in S930, the number of service rectifiers is not included in the number H.

  In the subsequent S940, among the charging stations set as the service station, the charging station whose output from the service rectifier is stopped by the process of S930 (that is, the charging station in which the power supply from the service rectifier has been stopped). If there is no charging station whose output from the service rectifier stops (S940: NO), the process proceeds to S950, but if there is a charging station whose output from the service rectifier stops ( (S940: YES), in S945, the service flag set in the service stand is cleared.

  Next, the rectifier securing process executed in the present embodiment (the process executed in S350 in FIG. 10) will be described with reference to FIG. In the rectifier securing process of the present embodiment, first, in S1010, only the rectifier that is currently stopped (that is, the rectifier that is not used) is the number of units (Jb) required for charging in the newly requested charge menu. It is determined whether or not the rectifier is satisfied.

  And when it is judged that it is satisfied (S1010: YES), it progresses to S1040, Jb stand is secured from the rectifier currently stopped (not in use), and the rectification detected at present in S1050. The vacant number N is updated by subtracting the reserved number Jb from the vacant number N of the apparatus.

  On the other hand, if it is determined in S1010 that the required number of rectifiers that are currently stopped is not sufficient (S1010: NO), the process proceeds to S1020 to secure all the rectifiers that are currently stopped, and in S1030. The shortage that could not be secured in S1020 is satisfied by securing a rectifier that is operating as a service rectifier, and the process proceeds to S1050. It should be noted that which of the rectifiers operating as the service rectifier is to be secured is arbitrary.

  After updating the available number N in S1050, in S1060, whether there is a charging station in which charging power is not supplied from the service rectifier by the processing in S1030 among the charging stations set as the service station. to decide. And if there is no charging stand (service stand) from which the charging power supply from the service rectifying device has been lost (S1060: NO), this rectifying device securing process is terminated as it is, but the charging power supply from the service rectifying device has been lost. If there is a charging stand (service stand) (S1060: YES), the process proceeds to S1070, and the service flag set in the service stand is cleared.

  According to the charging station of the third embodiment described above, the charging station is not limited to charging with a regular number of rectifiers corresponding to the selected charging menu, but can further increase charging power. In addition, if there is another unused rectifier, the unused rectifier can be used as a service rectifier, and charging power can be supplied from the service rectifier. Therefore, the charging can be completed in a time shorter than the charging time originally required for the charging in the selected charging menu, so that the convenience for the user can be further improved and the user can be highly satisfied.

  In addition, the service rectifier is used only when there is another unused rectifier that does not need to be supplied with power, and if there is a new charge request, If the rectifier operating as a service rectifier is not enough, and the rectifier operating as a service rectifier is also required, the service rectifier is stopped and the new Operate for charging. Therefore, as long as there is a vacancy, charging of the user who is charging can be completed more quickly without affecting whether or not charging by a new charging request is possible.

  In the present embodiment, the service rectifier corresponds to the service supply means of the present invention. In the system operating state optimization process of FIG. 15, the process of S955 corresponds to the process executed by the supplier increase possibility determination unit of the present invention.

[Modification]
Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to the above-described embodiments, and can take various forms as long as they belong to the technical scope of the present invention. Needless to say.

  For example, in the above-described embodiment, an example in which AC power from the commercial AC power supply 2 is distributed is shown. However, the number of distributions, the number of rectifiers, the number of input terminals and output terminals in the switch 4, The number of charging stations is merely an example, and can be determined as appropriate. The switch 4 may be provided with a smaller number of output terminals than the number of rectifiers (number of input terminals), and a charging stand corresponding to the number of output terminals may be provided. Further, the fact that the AC power of the commercial AC power supply 2 is 100 kW is merely an example.

Moreover, it is not always necessary to use the same rectifiers 11 to 20 (the same output power rating).
Further, the configuration in which AC power is converted to DC power by a rectifier and output is merely an example, and AC power is distributed to each charging station as it is (or appropriately transformed) as it is (or extended). To the vehicle). However, in that case, the vehicle side needs to be configured to be able to be charged with AC power.

  In the above embodiment, the charging station 1 side (the control device 5) performs the charging control (CVCC), the charging time prediction calculation, and the like. It may be configured to receive information (necessary charging power / current / voltage, SOC, charging start / end command, estimated required time, etc.) and supply charging power according to them. In this case, desired electric power can be supplied to the vehicle by controlling the switch 4 according to a command from the vehicle.

  In the above embodiment, the charge rate is calculated based on a pay-as-you-go system based on a common unit price, and is multiplied by a charge premium coefficient K. However, such a charge calculation method is merely an example. However, various fee calculation methods different from this can be adopted. For example, a different unit price may be set for each charging menu from the beginning. As for the settlement method, the above-described cash, prepaid card, and credit card are merely examples.

  Furthermore, the calculation of the charging fee does not necessarily have to be performed in the control device 5, but for example, necessary information (charging power amount, charging menu, etc.) is transmitted to a remote server connected via a network. The calculation can be performed by the server, and the calculation result can be received again by the charging station and displayed to the user.

The display screens shown in FIGS. 4 to 7 and 12 are merely examples, and the display method, display contents, and the like can be determined as appropriate.
Further, in the above embodiment, when a charging menu whose availability information is displayed as “impossible” on the initial menu screen of FIG. 5 is selected, a reservation impossible display (S410 in FIG. 10) is performed, and then FIG. Although the reselection screen of (a) is displayed and the process proceeds to accepting a reservation, the reservation may be accepted immediately on the initial screen of FIG.

Furthermore, not only the charging menu that cannot be executed immediately, but also the charging menu that can be executed immediately may be accepted.
In addition, information useful for a user who is going to perform charging such as the information shown in FIG. 4 can be obtained and confirmed from a remote location by accessing the control device 5 using a communication line such as the Internet. May be. Further, it may be possible to make a reservation by e-mail or the Internet.
