Description

  The present invention relates to a power supply control device that controls power supplied from a commercial power supply via a power outlet to a storage battery mounted on a vehicle, and a power supply control system.

  In recent years, plug-in vehicles configured to charge a storage battery (battery) using a commercial power source have attracted attention in electric vehicles and hybrid vehicles. In addition, various devices, methods, and the like have been proposed as measures against theft of electricity when charging a plug-in vehicle from a commercial power source.

  For example, when the vehicle-side connector is connected to the station-side connector, if the electronic authentication control unit provided in the station detects the presence of a legitimate electronic authentication key, charging from the commercial power source to the storage battery is permitted. A plug-in vehicle management system that rejects charging from a commercial power source to a storage battery when an electronic authentication control unit provided in a station does not detect the presence of a regular electronic authentication key is disclosed (Patent Document 1). reference).

  However, in the plug-in vehicle management system described in Patent Document 1, once the electronic authentication control unit provided in the station detects the presence of a regular electronic authentication key, charging from the commercial power source to the storage battery is permitted. Therefore, there is a possibility that the plug is replaced and the power is stolen during the subsequent charging (or after the charging is completed).

  In addition, since it is necessary to provide an electronic authentication control unit that detects the presence of the electronic authentication key in the station, the configuration of the apparatus becomes complicated. Furthermore, since it is determined whether or not the user is a legitimate user based on the electronic authentication key, even if the legitimate user desires charging, the electronic authentication key of the vehicle is provided in the station. When the vehicle is not registered in the control unit, the vehicle cannot be charged, and it cannot be said that the convenience is sufficient. Here, “when the electronic authentication key of the vehicle is not registered” means, for example, that an authorized user uses a storage battery such as an electric vehicle for an electric vehicle owned by a friend / acquaintance of the authorized user. There may be a case where the user wants to charge the battery or a case where the authorized user uses a substitute electric vehicle for some reason and the authorized user wants to charge a storage battery such as the electric vehicle.

  The server device 1 is communicably connected to the authentication control device 2 and the mobile phone 7 via the Internet 8 and controls the operation of the entire power supply control system 100. The server device 1 receives the authentication information from the authentication control device 2 and performs personal authentication processing by collating with authentication information registered in advance. In addition, the server device 1 receives power value information and the like obtained by the relay controller 3 detected by the CT 5 from the authentication control device 2, and performs determination such as full charge, power theft, and instantaneous power failure. Further, the server device 1 transmits, to the authentication control device 2, instruction information for displaying various screens, instruction information for opening (or closing) the relay 4, and the like. In addition, the server device 1 transmits various mails to the mobile phone 7.

  The authentication control device 2 is disposed, for example, in the vicinity of the entrance / exit of a parking lot where an electric vehicle that desires charging of a storage battery is parked (see FIG. 3), and user authentication information (here, for example, an IC card) The stored user ID information) is received and transmitted to the server device 1, and identification information (for example, parking lot number information) of the parking lot that the user desires to park is transmitted to the server device 1.

  Further, the authentication control device 2 is communicably connected to a plurality (for example, 32) of relay controllers 31, 32,..., 3n (here, n = 32). Since the relay controllers 31, 32,..., 3n have the same configuration, they may be collectively referred to as the relay controller 3 in the following description. In addition, identification information (here, IP address) is set in advance in each of the relay controllers 31, 32,..., 3n.

Relay controllers 31, 32,..., 3n (here, n = 32) have relays 41, 42,..., 4n (here, n = 32) and CTs 51, 52,. .. 5n (here, n = 32) are connected. Relays 41, 42, ...
4n has the same configuration, and therefore may be collectively referred to as a relay 4 in the following description. The relay 4 corresponds to a part of the blocking means described in the claims. In addition, since CT51, 52,..., 5n have the same configuration, they may be collectively referred to as CT5 in the following description. CT5 corresponds to part of the detection means described in the claims.

This is to switch between enabling or shutting off the power supply. Note that the instruction information for switching between power supply and interruption with respect to the relay 4k is sent from the server device 1 and input as an instruction signal to the relay 4k via the authentication control device 2 and the relay controller 3k sequentially. In addition, since the outlets 61, 62,..., 6n have the same configuration, they may be collectively referred to as the outlet 6 in the following description.

Sent.

In addition, the relay controller 3k (k = 1, 2,..., N−1) is input from the server device 1 and the instruction information for switching between power supply and cutoff input via the authentication control device 2 is input. In this case, it is determined whether or not the IP address included in the instruction information matches the IP address assigned to the relay controller 3k. When the IP address included in the instruction information matches the IP address assigned to the relay controller 3k, the relay 4k is controlled to open and close according to the instruction information. If the IP address included in the instruction information does not match the IP address assigned to the relay controller 3k, the instruction information is sent to the lower relay controller 3 (k + 1).

For example, when the relay controller 3 is operating normally, the green LED is lit. Further, when the relay 4 is in the ON state and the battery is charged normally, the red LED is lit. Further, when an abnormality such as electric leakage is detected, the red LED blinks.

-Functional configuration of power supply control system 100-
FIG. 6 is a block diagram illustrating an example of a functional configuration of the power supply control system 100 illustrated in FIG. 1. The server device 1 includes a CPU, ROM, RAM, HDD (Hard disk drive), and the like. The CPU reads and executes a control program or the like stored in a ROM or the like. The ROM is a memory that stores a control program and the like in advance. The RAM is a memory used as a working memory, a temporary storage memory, or the like. The HDD is a memory that stores various information such as ID information used for personal authentication.

  Here, the server device 1 reads out the control program stored in the ROM and executes it by the CPU, whereby the charging determination unit 101, duration calculation unit 102, power theft determination unit 103, instantaneous power failure determination unit 104, charging It functions as a period estimation unit 105, a charging period calculation unit 106, a charging period determination unit 107, a full charge determination unit 108, a trouble determination unit 109, an authentication unit 110, and an opening / closing instruction unit 111.

  Here, the relay controller 3 functions as the opening / closing unit 301 and the detecting unit 302 by reading out a control program stored in the ROM 312 and executing it by the CPU 311.

  The opening / closing unit 301 is a functional unit that turns the relay 4 on and off based on an instruction from the server device 1 (here, the opening / closing instruction unit 111). Here, the opening / closing part 301 corresponds to a part of the blocking means described in the claims. Specifically, the instruction information from the server device 1 is transmitted to the opening / closing unit 301 of the relay controller 3 via the Internet 8 and the authentication control device 2.

  The detection unit 302 is a functional unit that calculates a power value based on the current value signal detected by the CT 5 and outputs the calculated power value information to the server device 1 (here, the charging determination unit 101). . Here, the detection unit 302 corresponds to part of the detection means described in the claims. Specifically, the power value information from the detection unit 302 of the relay controller 3 is transmitted to the charging determination unit 101 of the server device 1 via the authentication control device 2 and the Internet 8.

  The authentication unit 110 performs personal authentication processing and outlet selection processing, and turns on the relay 4 corresponding to the outlet number selected in the outlet selection processing via the opening / closing instruction unit 111 and the opening / closing unit 301 to turn on the vehicle. It is a functional unit that enables power supply to the mounted storage battery.

The authentication unit 110 receives user ID information stored in an IC card or the like from the authentication control device 2 as a personal authentication process, and the received user ID information is registered in advance and registered users recorded in the HDD or the like. It is determined whether or not it matches any of the ID information. That is, it is determined whether or not the user ID information received from the authentication control device 2 is registered.

  If it is determined that the user ID information is registered, the authentication unit 110 performs an outlet selection process. That is, the authentication unit 110 receives the outlet number information from the authentication control device 2 as the outlet selection process, and determines whether or not the received outlet number can be selected. Note that the authentication unit 110 determines that the accepted outlet number is selectable when the following conditions A and B are satisfied, for example.

Condition A: The section corresponding to the accepted outlet number is not in use Condition B: No reservation is made for another user in the section corresponding to the accepted outlet number The authentication unit 110 can select the outlet number. When it is determined that there is, the relay 4 corresponding to the selected outlet number is turned on via the open / close instruction unit 111 and the open / close unit 301 to enable power supply to the storage battery mounted on the vehicle.

  The charging determination unit 101 is a functional unit that determines whether or not the power value transmitted from the detection unit 302 of the relay controller 3 is equal to or less than a preset power threshold Wth (for example, 3 W). Here, the charging determination unit 101 corresponds to the charging determination unit described in the claims.

  In the present embodiment, a case where the charging determination unit 101 determines whether the power value transmitted from the detection unit 302 of the relay controller 3 is equal to or less than a preset power threshold Wth will be described. The charging determination unit 101 may determine whether or not the current value transmitted from the detection unit 302 of the relay controller 3 is equal to or less than a preset current threshold value. In the present embodiment, the case where the power threshold value Wth is 3 W will be described. However, the power threshold value Wth is based on the model of the storage battery mounted on the vehicle, the charging control method for the storage battery on the vehicle side, etc. It is also possible to use a form set in advance. In this case, a more appropriate value can be set as the power threshold value Wth.

  The duration calculation unit 102 is transmitted from the detection unit 302 of the relay controller 3 when it is determined by the charging determination unit 101 that the power value transmitted from the detection unit 302 of the relay controller 3 is equal to or less than the power threshold Wth. This is a functional unit that obtains a duration P that is a duration during which a state where the power value is equal to or less than the power threshold value Wth. Here, the duration calculation unit 102 corresponds to duration calculation means described in the claims.

  The power theft determination unit 103 is a functional unit that determines the possibility of power theft based on the power value transmitted from the detection unit 302 of the relay controller 3. Here, the theft determination unit 103 corresponds to a theft determination unit described in the claims. The power theft determination unit 103, specifically, the duration P obtained by the duration calculation unit 102 is less than a preset first time threshold Pth1 (for example, 10 seconds), and When it is equal to or greater than the set third time threshold value Pth3 (for example, 1 second), it is determined that there is a possibility of theft.

  Further, if the theft determination unit 103 determines that there is a possibility of theft, it corresponds to the owner (user) of the vehicle that has been charged through the outlet 6 that has been determined to have the possibility of theft. An email indicating that there is a possibility of theft is transmitted to the mobile phone 7. The trouble determination unit 109 transmits, for example, an e-mail saying “There is a possibility that a power theft has been performed during charging in the parking lot of XX, and charging has been interrupted”. Here, XX is the name of the user, and xx is the name of the parking lot where the vehicle is parked.

  In this way, if the duration P is less than the preset first time threshold Pth1 and is equal to or greater than the preset third time threshold Pth3, it is determined that there is a possibility of theft. Therefore, by setting the first time threshold value Pth1 and the third time threshold value Pth3 to appropriate values, it is possible to more accurately determine the possibility of theft.

  That is, for example, when the plug connected to the outlet 6 is replaced during charging and theft is performed, the power value supplied from the commercial power source to the storage battery is once “0 W” when the plug is removed from the outlet 6. After that, the power value supplied from the commercial power source to the storage battery increases when the plug is connected to the outlet 6. Therefore, in this case, if the first time threshold value Pth1 is set to the longest value (for example, 10 seconds) from the time when the plug is removed from the outlet 6 to the time when the plug is connected to the outlet 6, It is possible to more accurately determine the presence or absence of the possibility.

  In addition, when an instantaneous power failure occurs during charging, when the instantaneous power failure occurs, after the power value supplied from the commercial power source to the storage battery once becomes “0 W”, The power value supplied from the commercial power source to the storage battery will increase. Therefore, in this case, if the third time threshold value Pth3 is set to the maximum value (for example, 1 second) of the duration time P when an instantaneous power failure occurs, the presence / absence of theft of electricity is more accurately determined. be able to.

  In the present embodiment, a case in which the theft determination unit 103 determines that there is a possibility of theft when the duration P is less than the first time threshold Pth1 and equal to or greater than the third time threshold Pth3. As will be described, a form may be adopted in which the theft determination unit 103 determines that there is a possibility of theft when it is less than the first time threshold value Pth1. In this case, the process is simplified.

  The instantaneous power failure determination unit 104 is a functional unit that determines whether or not an instantaneous power failure has occurred in the commercial power source. Here, the instantaneous power failure determination unit 104 corresponds to instantaneous power failure determination means described in the claims. Specifically, the instantaneous power failure determination unit 104 determines that an instantaneous power failure has occurred in the commercial power supply when the duration P is less than the third time threshold value Pth3.

  In this way, when the duration P is less than the third time threshold value Pth3, it is determined that an instantaneous power failure has occurred in the commercial power supply. Therefore, the third time threshold value Pth3 is an appropriate value (for example, 1 second). By setting to, it can be accurately determined that an instantaneous power failure has occurred.

  The charging period estimation unit 105 is a functional unit that estimates a charging required period PF that is a period required from when charging of a storage battery mounted on a vehicle is started until it becomes a fully charged state. Here, the charging period estimation unit 105 corresponds to charging period estimation means described in the claims. In the present application, the “fully charged state” means a state in which the storage battery is charged to a predetermined amount of charge based on the rated capacity of the storage battery mounted on the vehicle, and the state in which the storage battery is charged to the rated capacity is not necessarily used. It doesn't mean. In addition, the charging period estimation unit 105 estimates the remaining capacity of the storage battery based on a change in the power value supplied from the commercial power source to the storage battery for a predetermined period (for example, 5 minutes) from the start of charging, for example. Based on the capacity, the charge required period PF0 is obtained.

  The charging period calculation unit 106 determines that the power value transmitted from the detection unit 302 of the relay controller 3 by the charging determination unit 101 after the charging of the storage battery mounted on the vehicle is less than or equal to the power threshold Wth. This is a functional unit for obtaining a charging execution period PFA that is a period up to the time point. Here, the charging period calculation unit 106 corresponds to charging period calculation means described in the claims.

  The charging period determination unit 107 is a functional unit that determines whether the ratio R of the charging execution period PFA to the charging required period PF0 is equal to or greater than a preset ratio threshold Rth (for example, 0.7). Here, the charging period determination unit 107 corresponds to a charging period determination unit described in the claims.

  The full charge determination unit 108 is determined by the charge period determination unit 107 that the ratio R of the charge execution period PFA to the charge required period PF0 is equal to or greater than a preset ratio threshold Rth, and is obtained by the duration calculation unit 102. This is a functional unit that determines that the storage battery is in a fully charged state when the duration P is equal to or longer than a preset second time threshold value Pth2 (for example, 10 seconds). Here, the full charge determination unit 108 corresponds to the full charge determination means described in the claims. Further, the second time threshold value Pth2 is set to the same value (here, 10 seconds) as the first time threshold value Pth1, for example.

  Further, when the full charge determination unit 108 determines that the storage battery is in a fully charged state, it corresponds to the owner (user) of the vehicle that has been charged through the outlet 6 that is determined to be in the fully charged state. A mail indicating that the battery is fully charged is transmitted to the mobile phone 7 that performs the operation. The full charge determination unit 108 transmits, for example, an e-mail indicating that “charging at XX parking lot of XX has been completed”. Here, XX is the name of the user, and xx is the name of the parking lot where the vehicle is parked.

  In this way, it is determined whether or not the ratio R of the charge execution period PFA to the charge required period PF0 is equal to or greater than a preset ratio threshold Rth, is determined to be equal to or greater than the ratio threshold Rth, and the duration P Is greater than or equal to the preset second time threshold value Pth2, it is determined that the storage battery is fully charged, so by setting the ratio threshold value Rth and the second time threshold value Pth2 to appropriate values, It can determine more accurately that the storage battery is fully charged.

  In the present embodiment, when the full charge determination unit 108 has the ratio R equal to or greater than a preset ratio threshold Rth and the duration P is equal to or greater than a preset second time threshold Pth2, A case will be described in which it is determined that the battery is in a fully charged state, but the full charge determining unit 108 determines that the storage battery is in a fully charged state when the duration P is greater than or equal to a preset second time threshold value Pth2. But you can. In this case, the process is simplified.

  In the present embodiment, the case where the ratio threshold Rth is 0.7, for example, will be described. However, the ratio threshold Rth is set to a larger value as the estimation accuracy of the required charging period PF0 by the charging period estimation unit 105 is higher. It is preferable. In this case, an appropriate value can be set as the ratio threshold Rth.

  Furthermore, in the present embodiment, the second time threshold value Pth2 is set to the same value (here, 10 seconds) as the first time threshold value Pth1. Thus, since the second time threshold value Pth2 is set to the same value as the first time threshold value Pth1, when the duration time P is equal to or longer than the first time threshold value Pth1 (here, 10 seconds) The full charge determination unit 108 determines that the battery is fully charged (or the trouble determination unit 109 determines that a trouble has occurred), and the power supply to the storage battery is interrupted. If the duration P is less than the second time threshold value Pth2 (= first time threshold value Pth1: 10 seconds in this case), the theft determination unit 103 determines that there is a possibility of theft and transfers the battery to the storage battery. The power supply of is cut off. Therefore, it is possible to more effectively prevent theft.

The trouble determination unit 109 is a functional unit that determines that a trouble that makes it impossible to supply power to the storage battery during charging (hereinafter also simply referred to as “trouble”) has occurred. here,
The trouble determination unit 109 corresponds to trouble determination means described in the claims. Specifically, the trouble determination unit 109 determines that the ratio R of the charge execution period PFA to the charge required period PF0 is less than the preset ratio threshold Rth, and the second duration P is preset. If it is equal to or greater than the time threshold value Pth2, it is determined that a trouble has occurred.

  In addition, when the trouble determination unit 109 determines that there is a trouble that makes it impossible to supply power to the storage battery during charging, the trouble determination unit 109 passes through the outlet 6 that is determined to have a trouble. An e-mail indicating that a trouble has occurred is transmitted to the mobile phone 7 corresponding to the owner (user) of the charged vehicle. The trouble determination unit 109 transmits, for example, an e-mail indicating that a trouble that makes it impossible to supply power has occurred during charging in the parking lot of XX, and charging has been interrupted. Here, XX is the name of the user, and xx is the name of the parking lot where the vehicle is parked.

  Thus, it is determined that the ratio R of the charge execution period PFA to the charge required period PF0 is less than the preset ratio threshold Rth, and the duration P is equal to or greater than the preset second time threshold Pth2. In this case, since it is determined that a trouble has occurred, it is accurately determined that a trouble has occurred by setting the ratio threshold Rth and the second time threshold Pth2 to appropriate values. Can do.

  FIG. 7 is a graph showing an example of charging power detected by the power supply control system 100 shown in FIG. 1 in the case of theft or full charge. The horizontal axis of the graph is time t, and the vertical axis is the power value (hereinafter also referred to as “charging power value”) supplied from the commercial power source to the storage battery. FIG. 7A is a graph G1 showing an example of the change in the charging power value in the case of full charge, and FIG. 7B is a graph G2 showing an example of the change in the charging power value in the case of theft. FIG. 7C is a graph G3 illustrating an example of a change in the charging power value in the case of a momentary power failure.

  As shown by graph G1 in FIG. 7A, in the case of full charge, once the charge power value becomes equal to or less than the power threshold value Wth, the state is continued. That is, the duration P is equal to or longer than the first time threshold value Pth1 (for example, 10 seconds).

  Further, as shown by a graph G2 in FIG. 7B, in the case of theft, when the plug is removed from the outlet 6, the charging power value once becomes equal to or lower than the power threshold value Wth and then another vehicle. The charging power value increases after the time when the plug is connected to the outlet 6, and again becomes a value larger than the power threshold value Wth. In the case of power theft, it is difficult to assume that the plug will be replaced slowly, so the duration P2 is less than the first time threshold Pth1 (for example, 10 seconds). That is, in the case of theft, the duration P2 in which the charging power value is equal to or less than the power threshold value Wth is less than the second time threshold value Pth2 (for example, 10 seconds).

  Furthermore, as shown by graph G2 in FIG. 7C, in the case of an instantaneous power failure, the instantaneous power failure is resolved after the charge power value once falls below the power threshold Wth when the instantaneous power failure occurs. At that time, the charging power value increases and becomes a value larger than the power threshold Wth again. That is, in the case of an instantaneous power failure, the duration P3 in which the charging power value is equal to or less than the power threshold value Wth is less than the third time threshold value Pth2 (for example, 1 second).

Returning to FIG. 6 again, the functional configuration of the server device 1 will be described. The open / close instruction unit 111 is based on the determination results of the power theft determination unit 103, the instantaneous power failure determination unit 104, the full charge determination unit 108, the trouble determination unit 109, and the authentication unit 110, and the electric power supplied to the storage battery mounted on the vehicle. This is a functional unit that starts and shuts off the supply. Here, the opening / closing instruction unit 111 corresponds to a blocking instruction means described in the claims.

  Specifically, the opening / closing instruction unit 111 instructs the relay controller 3 to turn on or off the relay 4 via the Internet 8 and the authentication control device 2. When the authentication unit 110 performs personal authentication and determines that the outlet number is selectable, the opening / closing instruction unit 111 turns on the relay 4 corresponding to the outlet number selected by the authentication unit 110. The power supply to the storage battery mounted in the vehicle is enabled.

  Further, when the theft determination unit 103 determines that theft is occurring, the opening / closing instruction unit 111 blocks the supply of power to the storage battery mounted on the vehicle. Furthermore, when it is determined by the instantaneous power failure determination unit 104 that an instantaneous power failure has occurred, the open / close instruction unit 111 continues to supply power to the storage battery mounted on the vehicle (= not cut off).

  In addition, when the full charge determination unit 108 determines that the storage battery of the vehicle is in a fully charged state, the opening / closing instruction unit 111 blocks the supply of power to the storage battery mounted on the vehicle. Further, when it is determined by the trouble determination unit 109 that there is a trouble that makes it impossible to supply power to the storage battery during charging, the opening / closing instruction unit 111 supplies the storage battery mounted on the vehicle to the storage battery. Shut off the power supply.

  In this way, the power value supplied from the commercial power supply to the storage battery via CT5 is detected by the detection unit 302 of the relay controller 3, and based on the detection result, the possibility of theft is determined by the theft determination unit 103. When it is determined that there is a possibility of theft, the power supply to the storage battery is blocked by the opening / closing instruction unit 111 via the relay 4, so that theft can be effectively prevented.

  That is, for example, when the plug connected to the outlet 6 is replaced during charging and theft is performed, the power value supplied from the commercial power source to the storage battery is once “0 W” when the plug is removed from the outlet 6. After that, the power value supplied from the commercial power source to the storage battery increases when the plug is connected to the outlet 6. Therefore, based on the detection result of the power value supplied from the commercial power supply to the storage battery, it is possible to determine the possibility of theft.

  In this embodiment, the case where the detection unit 302 of the relay controller 3 detects the power value supplied from the commercial power source to the storage battery will be described. However, the detection unit 302 of the relay controller 3 is supplied from the commercial power source to the storage battery. The form which detects an electric current value may be sufficient. In this case, the configuration of the detection unit 302 of the relay controller 3 is simplified.

  In addition, when the full-charge determination unit 108 determines that the storage battery is in a fully charged state, the power supply to the storage battery is shut off via the relay 4 by the opening / closing instruction unit 111, so that the full-charge state is obtained. After the time point, even if the plug connected to the outlet 6 is replaced, it is not stolen, so that theft can be prevented more effectively.

  Furthermore, when the instantaneous power failure determination unit 104 determines that an instantaneous power failure has occurred, the switching instruction unit 111 continues without interrupting the supply of power to the storage battery via the relay 4. The storage battery can be charged until it reaches a charged state.

In addition, when it is determined by the trouble determination unit 109 that there is a trouble that makes it impossible to supply power to the storage battery during charging, the opening / closing instruction unit 111 supplies power to the storage battery via the relay 4. Since the supply is cut off, after the time when it is determined that a trouble has occurred, even if the plug connected to the outlet 6 is replaced, it will not be stolen, so that theft can be prevented more effectively. Can do.

-Operation of the entire power supply control system 100-
FIG. 8 is a ladder diagram showing an example of the operation of the power supply control system 100 shown in FIG. Hereinafter, an outline of the operation of the entire power supply control system 100 will be described with reference to FIG. First, in step T21, the ID information stored in the IC card or the like is read by the card reader 215 (see FIG. 4) of the authentication control device 2. Then, the read ID information is transmitted to the server device 1. Next, ID information is received by the server apparatus 1 (authentication part 110) in step T11.

  In step T12, the server device 1 (authentication unit 110) determines whether the ID information is registered ID information. If NO in step T12, the process proceeds to step T22. If YES in step T12, the process proceeds to step T23.

  In step T22, an error screen indicating that the personal authentication has failed is displayed on the LCD 216 of the authentication control apparatus 2, and the process returns to step T21. In step T23, a screen for displaying a guidance for prompting the user to input the number of the outlet 6 is displayed on the LCD 216 of the authentication control device 2. Next, in step T24, the input of the outlet number is accepted via the input unit 214 of the authentication control device 2. The accepted outlet number information is transmitted to the server device 1.

  In step T13, the server apparatus 1 (authentication unit 110) receives the outlet number information. In step T14, the server device 1 (authentication unit 110) determines whether the received outlet number can be selected. If NO in step T14, the process proceeds to step T25. If YES in step T14, the process proceeds to step T15.

  In step T25, an error screen indicating that the outlet selection has failed is displayed on the LCD 216 of the authentication control apparatus 2, and the process returns to step T24. In step T15, the server apparatus 1 (open / close instruction unit 111) transmits instruction information to the relay controller 3 to turn on the relay 4. In step T31, the relay controller 3 (opening / closing unit 301) turns on the relay 4 to start charging the storage battery mounted on the vehicle.

  Next, in step T32, the relay controller 3 (detector 302) detects the power value based on the current value from CT5. The detected power value information is transmitted to the server device 1. In step T <b> 16, the power value information is received from the relay controller 3 by the server device 1 (charging determination unit 101). In step T17, based on the power value information received by the server device 1 (theft determination unit 103, instantaneous power failure determination unit 104, full charge determination unit 108, trouble determination unit 109, and opening / closing instruction unit 111). It is determined whether or not to stop power feeding. If YES in step T17, the process proceeds to step T33. If NO in step T17, the process returns to step T16. In step T33, the relay controller 3 (opening / closing unit 301) turns off the relay 4, and charging of the storage battery mounted on the vehicle is terminated.

-Operation of relay controller 3 of power supply control system 100-
FIG. 9 is a flowchart showing an example of the operation of the relay controller 3 arranged in the power supply control system 100 shown in FIG. Hereinafter, the operation of the relay controller 3 will be described with reference to FIGS. 6 and 9. First, in step S301, the opening / closing unit 301 determines whether power supply start instruction information indicating that the relay 4 is to be turned on has been received from the server device 1 (open / close instruction unit 111). If NO in step S301, the process is in a standby state. If YES in step S301, the process proceeds to step S303.

  In step S303 (corresponding to step T31 in FIG. 8), the relay 4 is turned on by the opening / closing unit 301. Next, in step S305, a current value signal is acquired from CT5 by the detection unit 302. In step S307 (corresponding to step T32 in FIG. 8), the detection unit 302 calculates the power value supplied from the commercial power source based on the current value acquired in step S305. Next, in step S <b> 309, the power value information calculated in step S <b> 307 is transmitted to the server device 1 by the detection unit 302.

  Next, in step S <b> 311, the opening / closing unit 301 determines whether or not power supply stop instruction information indicating that the relay 4 is turned off has been received from the server device 1 (open / close instruction unit 111). If NO in step S311, the process returns to step S305, and the processes after step S305 are repeatedly executed. If YES in step S311, the process proceeds to step S313. In step S313 (corresponding to step T33 in FIG. 8), the relay 4 is turned off by the opening / closing unit 301, and the process returns to step S301.

-Operation of the authentication control device 2 of the power supply control system 100-
FIG. 10 is a flowchart showing an example of the operation of the authentication control device 2 disposed in the power supply control system 100 shown in FIG. Hereinafter, the operation of the authentication control apparatus 2 will be described with reference to FIGS. 4 and 10. Note that the following processing is all executed by the CPU 211 of the authentication control device 2. In step S201 (corresponding to step T21 in FIG. 8), it is determined whether or not the ID information stored in the IC card or the like has been acquired via the card reader 215. If NO in step S201, the process is in a standby state. If YES in step S201, the process proceeds to step S203.

  In step S203, the ID information acquired in step S201 is transmitted to the server device 1 (authentication unit 110). In step S205, it is determined whether or not information indicating that the authentication process has been successful is received from the server apparatus 1 (authentication unit 110). If NO in step S205 (when failure information is received), the process proceeds to step S207. If YES in step S205 (information indicating that the authentication process has been successful has been received), the process proceeds to step S209.

  In step S207 (corresponding to step T22 in FIG. 8), an error screen notifying that the authentication has failed is displayed on the LCD 216, the process is returned to step S201, and the processes after step S201 are repeatedly executed. In step S209 (corresponding to step T23 in FIG. 8), a screen prompting the LCD 216 to input the outlet number is displayed. Then, in step S211 (corresponding to step T24 in FIG. 8), it is determined whether or not an outlet number has been input via the input unit 214. If NO in step S211, the process is set to a standby state. If YES in step S211, the process proceeds to step S213. In step S213, it is determined whether or not information indicating that the outlet selection is permitted is received from the server device 1 (authentication unit 110).

If NO in step S213 (when information indicating that outlet selection is not permitted is received), the process proceeds to step S215. If YES in step S213 (when information indicating that outlet selection is permitted is received), the process proceeds to step S217. In step S215 (corresponding to step T25 in FIG. 8), an error screen notifying that the outlet selection has failed is displayed on the LCD 216, the process returns to step S209, and the processes after step S209 are repeatedly executed. In step S217, instruction information for turning on the relay 4 is transmitted to the relay controller 3 (opening / closing unit 301) corresponding to the outlet number selected in step S211.

  In step S219, it is determined whether or not power information is received from the relay controller 3 (detection unit 302). If NO in step S219, the process is set to a standby state.
