Description

  The present invention relates to a vehicle charging system used for charging an in-vehicle battery.

  Conventionally, electric vehicles such as an electric vehicle (EV) and a plug-in hybrid vehicle (PHV) using an electric motor (motor) as a travel drive source are known. Moreover, in these electric vehicles, when the voltage of the vehicle-mounted battery which supplies electric power to a motor falls, it is known that it is necessary to charge a vehicle-mounted battery. In addition, as a method for charging the in-vehicle battery, for example, the input side of an external charging device such as a power supply connector is connected to a household outlet, and the output side is connected to a charging connector of an electric vehicle. There is a method of charging by connecting the vehicle to a dedicated charging stand.

  In recent years, there has been proposed a technique for taking measures against theft of an electric vehicle using this charging action unique to the electric vehicle. For example, in Patent Document 1, this desk lamp obtains a vehicle ID code for authentication from a PHV connected to a charging desk and transmits it to a vehicle registration server, and registration ID verification is established at the vehicle registration server. If not, charging the PHV is not permitted, thereby making it impossible to charge the stolen vehicle, narrowing the traveling range of the stolen vehicle, and facilitating the tracking of the stolen vehicle. .

  Furthermore, in Patent Document 2, an EV charging control ECU connected to a household power supply via a charging cable performs authentication with this ID cable as an authentication device provided indoors, If the authentication is not established, charging to the EV is not permitted, so that charging without an ID box is disabled, and the vehicle theft prevention is improved by depriving the thief of the vehicle theft.

  When the charger confirmation unit 41 of the center server 4 determines that the charger is a legitimate charger, the main control unit 46 of the center server 4 responds to a connection request from the charger 2 with an authentication function and the charger communication unit A response signal is returned from 42 to the center communication unit 22 of the charger 2 with the authentication function, and communication between the center server 4 and the charger 2 with the authentication function is established. When the charger confirmation unit 41 of the center server 4 determines that the charger is not a regular charger, the main control unit 46 of the center server 4 instructs the charger communication unit 42 to charge the charger 2 with an authentication function. The communication with the center communication unit 22 is terminated.

  After communication between the center server 4 and the charger 2 with an authentication function is established, the main control unit 24 of the charger 2 with an authentication function reads the vehicle unique code from the above-mentioned RAM, and the vehicle unique code is centered. In addition to sending to the communication unit 22, the center communication unit 22 is instructed to transmit the vehicle specific code to the center server 4.

  When the center server 4 receives the vehicle specific code transmitted from the center communication unit 22 of the charger 2 with the authentication function by the charger communication unit 42, the center server 4 sends the vehicle specific code to the main control unit 46. Whether the vehicle unique code is present in the list of vehicle unique codes stored in the vehicle unique code list storage unit 44 is checked. And when this vehicle specific code exists in the said list | wrist, it determines with charging from the charger 2 with an authentication function permitted (that is, charge permission). If the vehicle specific code does not exist in the list, it is determined that charging from the charger with authentication function 2 is not permitted (that is, charging is not possible).

  Further, when the main control unit 46 of the center server 4 determines that charging is permitted, information indicating that charging from the charger 2 with authentication function is permitted is sent from the charger communication unit 42 to the charger 2 with authentication function. When charging is determined to be impossible, information indicating that charging from the charger 2 with an authentication function is not permitted is transmitted from the charger communication unit 42 toward the charger 2 with an authentication function. . Here, information indicating that charging from the charger 2 with authentication function is permitted and information indicating that charging from the charger 2 with authentication function is not permitted are referred to as chargeability information.

  When the charger communication unit 42 receives the charge availability information transmitted from the charger communication unit 42 of the center server 4, the charger 2 with authentication function sends the charge availability information to the main control unit 24. In addition, the main control unit 24 sends this chargeability information to the vehicle communication unit 21 and instructs the vehicle communication unit 21 to transmit the chargeability information to the charge control device 1.

  When the charge control device 1 receives the charge availability information transmitted from the vehicle communication unit 21 of the charger 2 with the authentication function by the charger communication unit 12, the charge control device 1 sends this charge availability information to the main control unit 15. The main control unit 15 determines that charging is permitted when the charging permission / inhibition information is information indicating that charging from the charger 2 with the authentication function is permitted. In addition, the main control unit 15 determines that charging is not possible when the charging permission / prohibition information is information indicating that charging from the charger 2 with the authentication function is not permitted.

  If the main control unit 15 determines that charging is not possible, the main control unit 15 prohibits charging from the charger 2 with the authentication function. When the main control unit 15 prohibits charging from the charger 2 with the authentication function, the main control unit 15 gives the connection state of the charge switching unit 14 from the external charger via the charging cable 18. The power to the in-vehicle battery 17 is switched to a state where the power is cut off, and charging from the charger 2 with the authentication function cannot be performed.

  When the main control unit 15 determines that charging is permitted, the main control unit 15 resets the number of unauthenticated charges stored in the information storage unit 11 to an initial value, and from the charger 2 with an authentication function. To charge. When the main control unit 15 permits charging from the charger 2 with the authentication function, the main control unit 15 gives the connection state of the charge switching unit 14 from the external charger via the charging cable 18. It is made to switch to the state which supplies the electric power to the vehicle-mounted battery 17, and charging from the charger 2 with an authentication function can be performed. Further, the main control unit 15 transmits a charge request signal for requesting the start of charging to the charger 2 with an authentication function via the charger communication unit 12. And the main control part 24 which received the charge request signal via the vehicle communication part 21 of the charger 2 with an authentication function obtains the connection state of the charge switching part 23 of the charger 2 with an authentication function from the power source 25. Is switched to a state of supplying to the charging control device 1 and charging from the charger 2 with the authentication function is performed.

  The number of unauthenticated charges stored in the information storage unit 11 is such that the main controller 15 reduces the remaining number of times one time from the initial value each time charging from the unauthenticated charger 3 described later is performed once. It has come to go. Note that the initial value here is a value that can be arbitrarily set, and in this embodiment, for example, 10 times.

  Then, the example in case the charge control apparatus 1 and the charger 3 without an authentication function are connected with the charging cable 18 is described. The charger 3 without the authentication function receives the vehicle specific code transmitted from the charger communication unit 12 of the charging control device 1 by the vehicle communication unit 31 and sends it to the main control unit 33. In the control unit 33, since the process using the vehicle specific code is not programmed, the above-described chargeability information is not transmitted to the charge control device 1 from the charger 3 without the authentication function. Therefore, the charging control device 1 does not receive the charging availability information by the charger communication unit 12.

  The main control unit 15 of the charging control device 1 counts the elapsed time since the vehicle unique code is transmitted from the charger communication unit 12, and the elapsed time without receiving the charge availability information by the charger communication unit 12. Exceeds the predetermined threshold (that is, when a time-out occurs), it is determined whether or not the number of unauthenticated charges stored in the information storage unit 11 is zero. Note that the predetermined threshold here is a value that can be arbitrarily set. When the main control unit 15 determines that the number of non-authenticated charges stored in the information storage unit 11 is greater than 0, the main control unit 15 stores no authentication stored in the information storage unit 11. The remaining number of times of charging is reduced by 1, and charging from the charger 3 without the authentication function is performed. When the main control unit 15 permits charging from the charger 3 without the authentication function, the main control unit 15 gives the connection state of the charge switching unit 14 from the external charger via the charging cable 18. It is made to switch to the state which supplies the electric power to the vehicle-mounted battery 17, and charging from the charger 3 without an authentication function can be performed. Further, the main control unit 15 transmits a charge request signal for requesting the start of charging to the charger 3 without the authentication function via the charger communication unit 12. The main control unit 33 that has received the charge request signal via the vehicle communication unit 31 of the charger 3 without the authentication function determines the connection state of the charge switching unit 32 of the charger 3 without the authentication function from the power source 34. Is switched to the state of supplying to the charging control device 1 and charging from the charger 3 without the authentication function is performed.

  In addition, when the main control unit 15 determines that the number of unauthenticated charging stored in the information storage unit 11 is 0, the main control unit 15 prohibits charging from the charger 3 without the authentication function. When the main control unit 15 prohibits charging from the charger 3 without the authentication function, the main control unit 15 gives the connection state of the charge switching unit 14 from the external charger via the charging cable 18. The power to the in-vehicle battery 17 is switched to a state where the power is cut off, and charging from the charger 3 without the authentication function cannot be performed.

  As described above, in the vehicle charging system 100, although it is possible to charge from the charger 3 without the authentication function, the number of times that the charging can be continuously performed from the charger 3 without the authentication function is limited. (10 times in this example), the charging with the authentication function accompanied by the authentication between the center server 4 and the charger 2 with the authentication function every time the charging is performed from the charger 3 without the authentication function a certain number of times. I have to receive the charge from the container 2.

  When the electric vehicle is stolen, the charging with the authentication function is performed by removing the vehicle specific code corresponding to the stolen electric vehicle from the list of vehicle specific codes stored in the vehicle specific code list storage unit 44. The charging from the battery 2 to the in-vehicle battery 17 is prohibited.

  Therefore, according to the above configuration, the charger 2 with an authentication function that can be charged only when authentication by communication with the center server 4 is established, and the charger 3 without an authentication function that can be charged without requiring authentication. Since the number of times that the in-vehicle battery 17 can be continuously charged from the charger 3 without an authentication function is limited, it is possible to have higher security. For example, by restricting the number of times that the in-vehicle battery 17 can be continuously charged from the charger 3 without the authentication function, the stolen vehicle is prevented from expanding the traveling range without limitation by repeating charging, and the stolen vehicle. Can be easily tracked, or the value of the stolen vehicle can be reduced compared to a regular vehicle in the charging function, so that the thief can be more likely to steal the vehicle and higher security can be realized.

  Further, according to the above configuration, charging of the in-vehicle battery 17 from the charger 3 without authentication function is not completely prohibited but charging of the in-vehicle battery 17 from the charger 3 without authentication function is continuously performed. Since it is limited to the number of times that can be performed, it is possible to charge the in-vehicle battery 17 from the charger 3 without the authentication function, compared to the configuration in which the charger 2 with the authentication function can only be charged. Therefore, it has higher versatility. As a result, according to the above configuration, it is possible to have higher security while having higher versatility.

  Furthermore, according to the above configuration, each time the vehicle-mounted battery 17 is charged from the charger 2 with an authentication function, the number of times that it can be charged without authentication can be restored to the initial value. The electric vehicle that can charge the vehicle-mounted battery 17 from the vehicle can freely travel while repeatedly charging the vehicle-mounted battery 17 from the charger 2 with the authentication function and charging the vehicle-mounted battery 17 from the charger 3 without the authentication function. It becomes possible to expand to.

  Note that, as described above, in the vehicle charging system 100, when the number of times that the non-authentication charge is possible becomes zero, charging of the in-vehicle battery 17 from the charger 3 without the authentication function is prohibited, but there is no authentication. Even when the number of chargeable times is 0, there is a case where charging is necessary. As an example, since the charger 2 with the authentication function did not exist in the vicinity, the in-vehicle battery 17 was inevitably continuously charged from the charger 3 without the authentication function, and the number of times the charge without authentication has reached zero. The case where only the charger 3 without the authentication function exists in the range that can be reached with the remaining charge amount is applicable. In preparation for such a case, the vehicle charging system 100 can charge the in-vehicle battery 17 from the charger 3 without the authentication function even when the number of times that the charging without authentication has reached zero. Function (hereinafter referred to as exception handling function).

  Hereinafter, the above-described exceptional measure function will be described with reference to FIG. FIG. 8 is an example of a sequence diagram illustrating a data flow in the vehicle charging system 100. Here, the following description will be continued on the assumption that the allowable number of times of charging without authentication has reached zero. In addition, the initial value of the number of times that can be charged without authentication is 10 times.

  First, the operation input unit 51 of the mobile phone 5 receives input of mobile authentication information (user ID and password) from the user, and sends the received mobile authentication information to the main control unit 54. Upon receiving the mobile authentication information, the main control unit 54 temporarily stores the mobile authentication information in, for example, the RAM of the main control unit 54 and transmits a connection request signal from the center communication unit 52 to the center server 4 to request connection. To do. In response to this connection request, the main control unit 46 of the center server 4 returns a response signal from the mobile phone communication unit 43 to the center communication unit 52 of the mobile phone 5, and communication between the center server 4 and the mobile phone 5 is established. To do.

  After the communication between the center server 4 and the mobile phone 5 is established, the main control unit 54 of the mobile phone 5 reads out the mobile authentication information from the above-mentioned RAM and sends the mobile authentication information to the center communication unit 52. Then, the center communication unit 52 is instructed to transmit the mobile authentication information to the center server 4.

  When the center server 4 receives the mobile authentication information transmitted from the center communication unit 52 of the mobile phone 5 by the mobile phone communication unit 43, the center server 4 sends the mobile authentication information to the main control unit 46. It is checked whether the mobile authentication information is present in the mobile authentication information list stored in the mobile phone access list storage unit 45. If the mobile authentication information is present in the list, it is determined that charging is permitted (that is, charging is permitted). If the vehicle specific code does not exist in the list, it is determined that charging is not permitted (that is, charging is not possible).

  If the main control unit 46 of the center server 4 determines that charging is permitted, a charging permission code, which is data indicating permission for charging the in-vehicle battery 17, is directed from the mobile phone communication unit 43 to the mobile phone 5. To send. Therefore, the charge permission code corresponds to the charge permission information in the claims. If it is determined that charging is not possible, the charging permission code is not transmitted from the mobile phone communication unit 43 to the mobile phone 5.

  The cellular phone 5 counts the elapsed time since the mobile communication information was transmitted from the center communication unit 52, and the elapsed time exceeded a predetermined threshold without receiving the charging permission code by the center communication unit 52. In this case (that is, when a time-out occurs), the main control unit 54 determines that the authentication between the mobile phone 5 and the center server 4 has not been established. Then, for example, the main control unit 54 causes a display device (not shown) of the mobile phone 5 to display that authentication has not been established. Note that the predetermined threshold here is a value that can be arbitrarily set.

  In addition, when the center communication unit 52 receives the charge permission code transmitted from the mobile phone communication unit 43 of the center server 4, the mobile phone 5 sends the charge permission code to the main control unit 24. The main control unit 54 that has received the charge permission code temporarily stores the charge permission code in, for example, the RAM of the main control unit 54 and transmits a connection request signal from the vehicle communication unit 53 to the charge control device 1 to issue a connection request. Let it be done. In response to this connection request, the main control unit 15 of the charging control device 1 returns a response signal from the mobile phone communication unit 13 to the vehicle communication unit 53 of the mobile phone 5, and communication between the charging control device 1 and the mobile phone 5 is performed. Is established.

  After the communication between the charging control device 1 and the mobile phone 5 is established, the main control unit 54 of the mobile phone 5 reads the charging permission code from the above-mentioned RAM and sends this charging permission mode to the vehicle communication unit 53. The vehicle communication unit 53 is instructed to transmit this charge permission code toward the charge control device 1.

  When the mobile phone communication unit 13 receives the charge permission code transmitted from the vehicle communication unit 53 of the mobile phone 5, the charge control device 1 sends this charge permission code to the main control unit 15. When the main control unit 15 receives this charge permission code, the main control unit 15 increases the remaining number of times that can be charged without authentication stored in the information storage unit 11 by one.

  According to the above configuration, if authentication is performed by performing authentication using the mobile authentication information for authenticating whether or not the mobile phone 5 and the center server 4 are authorized users, Since the number of remaining chargeable times can be increased by one, if the user is a legitimate user, the remaining number of chargeable times without authentication can be increased, and convenience is further improved. For example, even if the remaining number of non-authenticated chargeable times has become 0, if the user is a legitimate user, the remaining number of non-authenticated chargeable times can be increased to charge the in-vehicle battery 17. When necessary, the in-vehicle battery 17 can be charged from the charger 3 without the authentication function, and the convenience is further enhanced. In addition, according to the above configuration, if the remaining number of rechargeable times without authentication is 0, if it is not a regular user, the remaining number of rechargeable times without authentication cannot be increased. The in-vehicle battery 17 cannot be charged from the charger 3 without the authentication function, and security is maintained.

  Furthermore, according to the above configuration, when authentication between the mobile phone 5 and the center server 4 is established, a charge permission code that is data indicating permission to charge the in-vehicle battery 17 is charged from the mobile phone 5. Since it is transmitted to the control device 1 by communication, it is difficult for a person other than the authorized user to illegally obtain the charge permission information, and it is possible to further improve the security.

  In the above-described embodiment, the configuration in which the user ID and the password received from the user by the operation input unit 51 of the mobile phone 5 are used as the mobile authentication information is not necessarily limited thereto. For example, it is good also as a structure which uses the body number of the mobile telephone 5 which is the information which identifies the mobile telephone 5 separately as information for mobile authentication. Therefore, the mobile authentication information corresponds to the second identifier information in the claims. In this case, the list of mobile authentication information stored in the mobile phone access list storage unit 45 of the center server 4 is a list of electric vehicles that are allowed to be charged from the charger 2 with an authentication function to the in-vehicle battery 17. What is necessary is just to make into the list | wrist of the body number of the mobile telephone 5 carried by regular users, such as an owner and an owner's family. Further, the machine number of the mobile phone 5 is stored in advance in a memory such as a ROM of the main control unit 54 and may be read by the main control unit 54 as necessary.

  Further, in the above-described embodiment, when the authentication using the mobile authentication information between the mobile phone 5 and the center server 4 is established as the exception measure function, the remaining number of times that can be charged without authentication is once. Although the structure to increase was shown, it is not necessarily restricted to this. For example, instead of the charging control device 1, when the charging control device 1 a that performs authentication based on the password entered by the user is used and the authentication based on the password is established, the remaining number of times that can be charged without authentication is calculated. It is good also as a structure increased once.

  Below, the structure of the charging control apparatus 1a is demonstrated using FIG. FIG. 9 is a block diagram showing a schematic configuration of the charging control device 1a. For convenience of explanation, members having the same functions as those shown in the drawings used in the description of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The charging control device 1a has a point that the mobile phone communication unit 13 is not provided, the operation input unit 61 is provided, and a password for authenticating whether or not the information storage unit 11 is a legitimate user in advance. Except for the registered points, the configuration is the same as that of the charge control device 1. Therefore, the information storage unit 11 corresponds to the charging control device side authentication code storage unit in the claims, and the personal identification number corresponds to the authentication code in the claims. Note that the personal identification number is composed of a combination of numbers, for example.

  First, the operation input unit 61 receives data input from the user. Specifically, the operation input unit 61 accepts input of a personal identification number from the user, and sends information on the accepted personal identification number to the main control unit 15. Therefore, the operation input part 61 is corresponded to the charge control apparatus side input part of a claim. The operation input unit 61 may be configured to use the operation input unit of the in-vehicle navigation device, or may be a touch switch integrated with the display device of the in-vehicle navigation device.

  In the main control unit 15 of the charging control device 1a, it is verified whether or not the code number received by the operation input unit 61 matches the code number stored in the information storage unit 11. And when it corresponds, the authentication using the personal identification number in the charge control apparatus 1a shall be materialized. If they do not match, it is assumed that authentication using the personal identification number in the charge control device 1a has not been established. Therefore, the main control unit 15 of the charge control device 1a corresponds to the authentication unit in the claims.

  In the main control unit 15, when the authentication using the above-described personal identification number is established, the remaining number of non-authentication rechargeable times stored in the information storage unit 11 is increased by one. Further, in the case where the authentication using the above-described personal identification number is not established, the main control unit 15 displays, for example, a display indicating that the authentication has not been established on a display device (not shown) of the charging control device 1a.

  In the present embodiment, a configuration using a personal identification number composed of a combination of numbers is shown, but the present invention is not necessarily limited thereto. For example, a code using a combination of characters or a combination of numbers and characters may be used.

  Even with the above configuration, if the remaining number of rechargeable times without authentication is 0, it is possible for the authorized user to increase the remaining number of rechargeable times without authentication, which is more convenient. Increases nature. Also, with the above configuration, if the remaining number of rechargeable times without authentication is zero, the remaining number of rechargeable times without authentication cannot be increased unless the user is authorized. The in-vehicle battery 17 cannot be charged from the battery charger 3 having no function, and security is maintained.

  In the above-described embodiment, in the case where the remaining number of rechargeable times without authentication is increased by the exception measure function, the configuration in which the remaining number of rechargeable times without authentication is increased by one is shown. Absent. For example, the number that increases the remaining number of times that can be charged without authentication may be configured to increase the number that is greater than one as long as the number of possible charging times without authentication falls within the initial value.

  Even with the above configuration, when the remaining number of rechargeable times without authentication is increased, it is increased at least within a range that falls within the initial value. Therefore, between the charger with authentication function 2 and the center server 4 at a certain rate. Authentication and authentication between the mobile phone 5 and the center server 4 are required, and security can be further improved.

  Further, in the above-described embodiment, when the remaining number of rechargeable times without authentication is 0, the configuration has been shown in which the remaining number of rechargeable times without authentication is increased by the exception measure function. Only when the remaining number of times is 0, the exception measure function may be configured to increase the remaining number of non-authenticated chargeable times, and is not limited to the case where the remaining number of unauthenticated chargeable times is 0. It is good also as a structure which increases the remaining frequency | count of the chargeable number of times without authentication with a function.

  In the above-described embodiment, the configuration in which the system includes the charger 2 with an authentication function for performing authentication using the vehicle specific code with the center server 4 is not necessarily limited thereto. For example, instead of the charger 2 with an authentication function, the system may include a charger 2a with an authentication function that does not perform authentication using a vehicle-specific code with the center server 4. Below, while explaining the structure of the charging system 200 for vehicles including the charger 2a with an authentication function using FIG. 10, the structure of the charger 2a with an authentication function is demonstrated using FIG. FIG. 10 is a block diagram showing a schematic configuration of the vehicle charging system 200. FIG. 11 is a block diagram showing a schematic configuration of the charger 2a with an authentication function. For convenience of explanation, members having the same functions as those shown in the drawings used in the description of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The vehicle charging system 200 is provided with an authentication function charger 2a instead of the authentication function charger 2 and does not include the center server 4 and the mobile phone 5, except for the vehicle charging system 200. The configuration is the same as 200. The charger 2a with an authentication function has the same configuration as the charger 2 with an authentication function, except that the center communication unit 22 is not provided and the vehicle-specific code list storage unit 71 is provided.

  First, the vehicle specific code list storage unit 71 is a non-volatile memory that stores in advance a list of vehicle specific codes of an electric vehicle that is allowed to be charged to the in-vehicle battery 17 from the charger 2a with an authentication function. This is the same memory as the vehicle specific code list storage unit 44 described above.

  When the charge control device 1a and the charger 2a with an authentication function are connected by a charge cable 18 via a plug (not shown), the main control unit 15 of the charge control device 1a for the electric vehicle is vehicle-specific from the information storage unit 11. The code is read, and this vehicle-specific code is transmitted from the charger communication unit 12 to the charger 2a with an authentication function.

  The charger with authentication function 2 a receives the vehicle specific code transmitted from the charger communication unit 12 of the charging control device 1 a by the vehicle communication unit 21 and sends it to the main control unit 24. Then, the main control unit 24 checks whether the vehicle unique code transmitted from the charge control device 1a exists in the list of vehicle unique codes stored in the vehicle unique code list storage unit 71. And when this vehicle specific code exists in the said list | wrist, it determines with charging from the charger 2a with an authentication function permitted (that is, charging permission). If the vehicle specific code does not exist in the list, it is determined that charging from the charger with the authentication function 2a is not permitted (that is, charging is impossible).

  In addition, when the main control unit 24 of the charger with authentication function 2a determines that charging is permitted, information indicating that charging from the charger 2a with authentication function is permitted from the vehicle communication unit 21 to the charge control device 1a. When it is determined that charging is not possible, information indicating that charging from the charger with authentication function 2a is not permitted is transmitted from the vehicle communication unit 21 toward the charger with authentication function 2a. Note that the information indicating that charging from the charger with authentication function 2a is permitted and the information indicating that charging from the charger with authentication function 2a is not permitted has the same function as the above-described chargeability information in the charging control device 1a. To do. That is, when the charging control device 1a receives information indicating that charging from the charger with authentication function 2a is permitted, charging from the charger with authentication function 2a to the vehicle-mounted battery 17 is performed, and the charging control device 1a. When the information indicating that charging from the charger with authentication function 2a is not permitted is received, charging of the in-vehicle battery 17 from the charger with authentication function 2a is prohibited.

  Even with the above configuration, the charger 2a with an authentication function that can be charged only when authentication with the charging control device 1a is established, and the charger 3 without an authentication function that can be charged without requiring authentication. When mixed, charging the in-vehicle battery 17 from the charger 3 without the authentication function is limited in the number of times that it can be continuously performed, so that it has higher versatility while having higher security. Enable.

  In the above-described embodiment, charging of the in-vehicle battery 17 from the charger 3 without the authentication function is limited by limiting the number of times that the in-vehicle battery 17 can be charged from the charger 3 without the authentication function. Although the configuration is shown, it is not necessarily limited to this. For example, the upper limit of the charge amount of the in-vehicle battery 17 when receiving the charging to the in-vehicle battery 17 from the charger 3 without the authentication function, and the in-vehicle battery in the case of receiving the charging from the charger 2 or 2a with the authentication function to the in-vehicle battery 17 It is good also as a structure which restrict | limits the charge to the vehicle-mounted battery 17 from the charger 3 without an authentication function by making it lower than the upper limit of the charge amount of 17. FIG.

  In the following, the upper limit of the charge amount of the in-vehicle battery 17 when receiving the charging to the in-vehicle battery 17 from the charger 3 without the authentication function, and the in-vehicle in the case of receiving the charging to the in-vehicle battery 17 from the authentication function charger 2 or 2a. The configuration of the charging control device 1b that limits charging from the charger 3 without the authentication function to the in-vehicle battery 17 by making it lower than the upper limit of the charging amount of the battery 17 will be described with reference to FIG. FIG. 12 is a block diagram illustrating a schematic configuration of the charging control device 1b. For convenience of explanation, members having the same functions as those shown in the drawings used in the description of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  Note that the vehicle charging system including the charging control device 1b is the same as the vehicle charging system 100 except that the charging control device 1b is included instead of the charging control device 1 and the processing related to the exceptional measure function is not performed. It is a configuration. The charging control device 1b has the same configuration as the charging control device 1 except that the mobile phone communication unit 13 is not provided and the information storage unit 11 does not store information on the number of times of charging without authentication.

  When the main control unit 15 receives the charge from the charger 2 or 2a with an authentication function to the in-vehicle battery 17 by the above-described authentication using the vehicle specific code, the connection state of the charge switching unit 14 is changed to the external The charger is switched to a state in which power supplied from the charger is supplied to the in-vehicle battery 17 via the charging cable 18, and charging from the charger 2 with the authentication function is performed until, for example, the in-vehicle battery 17 is fully charged.

  On the other hand, when the main control unit 15 is charged from the charger 3 without the authentication function to the in-vehicle battery 17, the connection state of the charge switching unit 14 is changed from the external charger via the charging cable 18. The state is switched to a state in which the supplied power is supplied to the in-vehicle battery 17, and charging from the charger 3 without the authentication function is performed until, for example, the in-vehicle battery 17 reaches 20% of full charge. When the on-vehicle battery 17 reaches 20% of full charge, the connection state of the charge switching unit 14 is cut off from the power supplied to the on-vehicle battery 17 from the external charger via the charging cable 18. The state is switched to a state in which the charger 3 without the authentication function cannot be charged any more.

  The charge amount of the in-vehicle battery 17 is determined by the main control unit 15 by monitoring the SOC (state of charge) of the in-vehicle battery 17 via, for example, a battery monitoring unit that is an ECU that monitors the charge amount of the in-vehicle battery 17. It shall be possible to adjust.

  Moreover, in this embodiment, when receiving the charge of the vehicle-mounted battery 17 from the charger 3 without an authentication function, the structure which can charge only to the charge amount of 20% of the full charge of the vehicle-mounted battery 17 was shown. However, this is not necessarily the case. Limitation of the amount of charge when charging the in-vehicle battery 17 from the charger 3 without the authentication function only needs to be a smaller amount than when receiving the charge from the charger 2 or 2a with the authentication function, and can be arbitrarily set It is. Further, when an in-vehicle navigation device that holds map data including position information of the chargers 2 and 2a with an authentication function is available, the vicinity of the current position of the electric vehicle equipped with the charging control device 1b (for example, the closest position) Etc.), the main control unit 15 calculates the charge amount of the in-vehicle battery 17 required to reach the charger with the authentication function 2 or 2a (hereinafter referred to as the required charge amount), and the charger 3 without the authentication function. In the case where the vehicle-mounted battery 17 is charged from the vehicle, it is possible to charge only the required amount of charge. Note that the required amount of charge is, for example, based on the distance from the current position of the electric vehicle to the charger with charge function 2 or 2a and the average power consumption of the in-vehicle battery 17 per distance traveled by the electric vehicle. What is necessary is just to set it as the structure to calculate.

  Also with the above configuration, the charger 2 with an authentication function and the charger 2a with an authentication function that can be charged only when the above-described authentication using the vehicle-specific code is established, and the authentication function that can be charged without requiring authentication When the battery charger 3 is mixed, the charging of the in-vehicle battery 17 from the battery charger 3 without the authentication function is limited, so that higher security can be achieved.

  In addition, it is good also as a structure which replaces the charging control apparatus 1b with the charging control apparatus 1a, and applies to the charging system 200 for vehicles.

  Further, for example, the charging efficiency when charging the in-vehicle battery 17 from the charger 3 without the authentication function is made lower than the charging efficiency when charging the in-vehicle battery 17 from the charger 2 or 2a with the authentication function. Thus, the charging from the charger 3 without the authentication function to the in-vehicle battery 17 may be limited.

  In the following, the charging efficiency when charging the vehicle-mounted battery 17 from the charger 3 without the authentication function is made lower than the charging efficiency when receiving the charging of the vehicle-mounted battery 17 from the charger 2 or 2a with the authentication function. Thus, the configuration of the charging control device 1c that restricts charging from the charger 3 without the authentication function to the in-vehicle battery 17 will be described with reference to FIG. FIG. 13 is a block diagram showing a schematic configuration of the charging control device 1c. For convenience of explanation, members having the same functions as those shown in the drawings used in the description of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The vehicle charging system including the charging control device 1c is the same as the vehicle charging system 100 except that the charging control device 1c is included instead of the charging control device 1 and that the processing related to the exceptional measure function is not performed. It is a configuration. In addition, the charging control device 1c includes a charging switching unit 81 instead of the charging switching unit 14, does not include the mobile phone communication unit 13, and does not store information on the number of unauthenticated chargings in the information storage unit 11. Except for this point, the configuration is the same as that of the charge control device 1.

  First, the charge switching unit 81 is controlled by the main control unit 15 to switch the electrical connection state, and supplies power supplied from the external charger via the charging cable 18 to the in-vehicle battery 17. Or shut off. In addition, the charge switching unit 81 is controlled by the main control unit 15 so that electric power (that is, current) given from an external charger via the charging cable 18 is changed between the large current rated adapter and the small current rated adapter. Which of these is switched to supply to the in-vehicle battery 17 is switched.

  The large current rated adapter and the small current rated adapter each pass a certain amount of current, and the large current rated adapter is designed to pass a larger amount of current than the small current rated adapter. Note that the high-current rated adapter and the small-current rated adapter may be configured with regulators having different amounts of current to be passed, or may be configured with resistors having different resistances.

  Moreover, the electrical connection state in the charge switching unit 81 may be switched using a switch or a relay, and the current is supplied to the in-vehicle battery 17 through either the large current rated adapter or the small current rated adapter. The supply may be switched by switching a switch or a relay.

  When the main control unit 15 receives the charge from the charger 2 or 2a with an authentication function to the in-vehicle battery 17 by the above-described authentication using the vehicle specific code, the connection state of the charge switching unit 14 is changed to the external The battery charger 17 is switched to a state in which power supplied from the battery charger 18 via the charging cable 18 is supplied to the vehicle-mounted battery 17 and is switched to a state in which the vehicle-mounted battery 17 is charged through the large current rated adapter.

  On the other hand, when the main control unit 15 is charged from the charger 3 without the authentication function to the in-vehicle battery 17, the connection state of the charge switching unit 14 is changed from the external charger via the charging cable 18. The state is switched to a state in which the supplied power is supplied to the in-vehicle battery 17 and is switched to a state in which the in-vehicle battery 17 is charged through the small current rated adapter. As described above, in the charging control device 1c, when the vehicle-mounted battery 17 is charged from the charger 3 without the authentication function, the vehicle-mounted battery 17 is charged at once from the charger 2 or 2a with the authentication function. By reducing the amount of current that can be passed, the charging efficiency is lowered, and it takes longer (for example, twice) to reach a predetermined amount of charge (for example, full charge).

  Also with the above configuration, the charger 2 with an authentication function and the charger 2a with an authentication function that can be charged only when the above-described authentication using the vehicle-specific code is established, and the authentication function that can be charged without requiring authentication When the battery charger 3 is mixed, the charging of the in-vehicle battery 17 from the battery charger 3 without the authentication function is limited, so that higher security can be achieved.

  In the present embodiment, the configuration in which the charging efficiency is switched depending on which of the large current rated adapter and the small current rated adapter is used to charge the in-vehicle battery 17 is shown, but the present invention is not necessarily limited thereto. For example, a variable resistor may be provided instead of the large current rated adapter and the small current rated adapter, and the amount of current flowing may be switched by switching the resistance of the variable resistor to switch the charging efficiency.

  Moreover, it is good also as a structure which replaces the charging control apparatus 1c with the charging control apparatus 1a, and applies to the charging system 200 for vehicles.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the technical means disclosed in different embodiments can be appropriately combined. Such embodiments are also included in the technical scope of the present invention.
