  When the power management device 5 and the vehicle 7 are connected via the cable 3 as will be described later, the communication unit 19a communicates with the communication unit 31a described later of the vehicle 7 via each communication line 20b, 3b, 30b. Then, communication is established, and the control device 19 and a control device 31 described later of the vehicle 7 are connected for communication.

  When the authentication information is input to the input receiving unit 13 by the person 21, the authentication unit 19 e stores the authentication information stored in advance in a storage unit 31 b described later of the vehicle 7 (hereinafter referred to as second authentication information). ) And verify only if they match. The authentication unit 19e outputs a result of the collation (that is, whether or not authentication has been performed) to the determination unit 19b, the power conversion control unit 19c, and the lock mechanism control unit 19d, and each communication line 20b, 3b, It outputs to the below-mentioned determination part 31e of the vehicle 7 via 30b.

In the case of failure, the power conversion device 15 is stopped.

  Further, when the authentication unit 19e authenticates after establishing communication between the communication units 19a and 31a, the power conversion control unit 19c locks the lock mechanisms 3e and 3f by the lock mechanism control unit 19d as described later, for example. After that (for example, after a later-described drive control unit 31d of the vehicle 7 prohibits the vehicle 7 from starting), the power conversion device 15 is operated. Since the power converter 15 is operated after the lock mechanisms 3e and 3f are locked, an electric shock can be prevented.

  The lock mechanism control unit 19d controls the lock / release of the lock mechanisms 3e and 3f. More specifically, when the authentication unit 19e authenticates after establishing communication between the communication units 19a and 31a, the lock mechanism control unit 19d locks the lock mechanisms 3e and 3f. As a result, the unauthorized removal of the cable 3 is prevented. When the lock mechanism control unit 19d locks the lock mechanisms 3e and 3f, a signal to that effect is sent from the lock mechanism control unit 19d to the drive control unit 31d (described later) of the vehicle 7 via communication between the communication units 19a and 31a. Sent.

  Further, when the authentication unit 19e or the later-described authentication unit 31c of the vehicle 7 performs authentication while the power conversion device 15 is operating, the lock mechanism control unit 19d, for example, after the power conversion device 15 stops, , 3f is released. Thereby, the cable 3 is pulled out without difficulty. In particular, since the lock mechanisms 3e and 3f are unlocked after the power converter 15 is stopped, an electric shock can be prevented.

It is configured to read. As such an input reception unit 27, for example, a so-called immobilizer in which authentication information for theft prevention is stored in the start key of the vehicle 7 can be used.

  Note that the input receiving unit 27 may be configured using a keyboard or a touch panel capable of inputting authentication information by a finger operation of the person 21 like the input receiving unit 13.

  The connector 29 is detachably connected to the connector 3d of the cable 3. The connector 29 is connected to a communication line 30b from a communication unit 31a (described later) of the vehicle 7 and a power line 30a from the storage battery 25.

And a drive control section 31d (drive control means) and a determination section 31e (first determination means).

  When the power management device 5 and the vehicle 7 are connected via the cable 3, the communication unit 31a establishes communication with the communication unit 19a of the power management device 5 via each communication line 30b, 3b, 20b. Then, the control device 19 of the power management device 5 and the control device 31 of the vehicle 7 are communicatively connected.

  The storage unit 31b includes authentication information input to the input receiving unit 13 and authentication information for authentication (second authentication information), and authentication information input to the input receiving unit 27 and authentication information for authentication (second authentication information). 1 authentication information) is stored. The first authentication information and the second authentication information may be the same or different.

  When the authentication information is input to the input receiving unit 27 by the person 21, the authentication unit 31c collates the input authentication information with the first authentication information stored in advance in the storage unit 31b, and they match. Authenticate only when. Further, the authentication unit 31c outputs the result of the collation (that is, the result of whether or not the authentication unit 31c has authenticated) to the determination unit 31e, and the determination of the control device 19 via each communication line 30b, 3b, 20b. Output to the unit 19b, the power conversion control unit 19c, and the lock mechanism control unit 19d.

  When the cable 3 is pulled out from the power management device 5 or the vehicle 7 and the communication between the communication units 19a and 31a is completed, the determination unit 31e determines whether or not the completion is a normal end through a predetermined processing procedure. Determine whether. More specifically, the determination is performed in the same manner as the determination unit 19b. The determination result is output from the determination unit 31e to the drive control unit 31d.

  When the drive control unit 31d receives a signal indicating that the lock mechanisms 3e and 3f are locked from the lock mechanism control unit 19d of the power management device 5 through communication between the communication units 19a and 31a, Driving is prohibited (in other words, power supply from the storage battery 25 to the motor 23 is prohibited). Thereby, the start drive of the vehicle 7 is prohibited.

  Further, the drive control unit 31d controls the motor 23 according to the driving operation of the driver of the vehicle 7 (in other words, controls power supply from the storage battery 25 to the motor 23). More specifically, the drive control unit 31d maintains the prohibition of power supply from the storage battery 25 to the motor 23 (that is, driving of the motor 23 (in other words, vehicle 7), and the power supply from the storage battery 25 to the motor 23 is permitted (that is, the vehicle 7 is permitted to start).

(Operation of power management system)
Next, the operation of the power management system 1 will be described with reference to FIG.

  In step S1, as shown in FIG. 1, a person 21 connects the connectors 3c and 3d of the cable 3 to the connector 17 of the power management device 5 and the connector 29 of the vehicle 7, respectively. Then, in step S2, the communication lines 20b, 3b, 30b between the communication unit 19a of the power management device 5 and the communication unit 31a of the vehicle 7 are connected by the connection, thereby connecting the communication units 19a, 31a. Communication is automatically established.

  In step S <b> 3, authentication information is input to the input receiving unit 13 of the power management apparatus 5 by the person 21. In step S4, the authentication unit 19e of the power management device 5 reads the second authentication information in the storage unit 31b of the vehicle 7 via each communication line 20b, 3b, 30b, and the input authentication information and Verification with the read second authentication information is performed. The collation result is output to the determination unit 19b, the power conversion control unit 19c, and the lock mechanism control unit 19d, and is also output to the determination unit 31e of the vehicle 7 through the communication lines 20b, 3b, and 30b. .

  In step S5, if the verification by the authentication unit 19e does not match (that is, if the authentication unit 19e does not perform authentication), the process proceeds to step S6, and the lock mechanism control unit 19d does not lock the lock mechanisms 3e and 3f. Furthermore, it progresses to step S7 and the power converter device 15 is not act | operated by the power conversion control part 19c. Then, the process returns to step S3.

  On the other hand, if the verification by the authentication unit 19e matches in step S5 (that is, if the authentication unit 19e performs authentication), the process proceeds to step S8, and the lock mechanisms 3e and 3f are locked by the lock mechanism control unit 19d. . Thereby, the connection between each connector 3c, 17 and the connection between each connector 3d, 29 are locked, respectively, and the cable 3 is prevented from falling off the power management device 5 and the vehicle 7. When the lock mechanisms 3e and 3f are locked, a signal to that effect is transmitted from the lock mechanism control unit 19d to the drive control unit 31d via communication between the communication units 19a and 31a.

  In step S9, the drive control unit 31d that has received the signal from the lock mechanism control unit 19d prohibits driving of the motor 23 (in other words, power supply from the storage battery 25 to the motor 23 is prohibited). . Thereby, the start drive of the vehicle 7 is prohibited.

  In step S <b> 10, the power conversion device 15 is activated by the power conversion control unit 19 c, and power supply is started between the power management device 5 and the storage battery 25 of the vehicle 7. Since the power converter 15 is operated after the locking mechanisms 3e and 3f are locked, electric shock is prevented. During the power supply, since the vehicle is prohibited from starting driving (step S9), the vehicle 7 is prevented from starting with the cable 3 connected.

  In this way (that is, as in steps S1 to S5, S8, and S10), the power conversion device 15 is activated after the cable 3 is connected to the power management device 5 and the vehicle 7 and locked.

  And when stopping electric power supply and making the vehicle 7 start, the process of step S11-S18 is performed. That is, in step S11, if there is an input of authentication information to the input receiving unit 13 by the person 21 in order to pull out the cable 3 from the power management apparatus 5 and / or the vehicle 7, the process proceeds to step S12. If the authentication information is not input to the input receiving unit 13 by 21, the process proceeds to step S 13.

  In step S12, the authentication unit 19e reads the second authentication information stored in advance in the storage unit 31b via each communication line 30b, 3b, 20b, and the input authentication information and the read second authentication information. 2 Verification with the authentication information is performed. The result of this collation is output from the authentication unit 19e to the determination unit 19b, the power conversion control unit 19c, and the lock mechanism control unit 19d, and to the determination unit 31e of the vehicle 7 via each communication line 20b, 3b, 30b. Is output. In step S12, if the verification by the authentication unit 19e matches (that is, if the authentication unit 19e performs authentication), the process proceeds to step S15, and if the verification by the authentication unit 19e does not match (that is, the authentication unit 19e performs authentication). If not, the process proceeds to step S13.

  In step S13, in order to pull out the cable 3 from the power management apparatus 5 and the vehicle 7, if the authentication information is input to the input receiving unit 27 by the person 21, the process proceeds to step S14. When there is no input of authentication information to the input reception part 27, it progresses to step S19.

  In step S14, the authentication unit 31c compares the input authentication information with the first authentication information stored in advance in the storage unit 31b. The result of this collation is output from the authentication unit 31c to the determination unit 31e, and the determination unit 19b, the power conversion control unit 19c, and the lock mechanism control unit of the power management apparatus 5 via the communication lines 30b, 3b, and 20b. It is output to 19d. In step S14, if the verification by the authentication unit 31c matches (that is, if the authentication unit 31c authenticates), the process proceeds to step S15, and if the verification by the authentication unit 31c does not match (that is, the authentication unit 31c does not authenticate). In the case), the process proceeds to step S19.

  That is, in steps S11 to S14, if there is authentication by the authentication unit 19e or the authentication unit 31c, the process proceeds to step S15. If there is no authentication of either the authentication unit 19e or the authentication unit 31c, the process proceeds to step S19.

  In step S15, the power conversion control unit 19c stops the power conversion device 15. In step S16, the lock mechanism controller 19d unlocks the lock mechanisms 3e and 3f. In this way, when there is authentication by the authentication unit 19e or the authentication unit 31c during power supply, the lock mechanisms 3e and 3f are unlocked after the power conversion device 15 is stopped. As a result, the cable 3 can be pulled out safely (without electric shock).

  In step S17, when the cable 3 is pulled out from the power management device 5 and / or the vehicle 7 by the person 21 and the communication between the power management device 5 and the vehicle 7 is completed, the determination units 19b and 31e It is determined whether the end is a normal end. In this case, since the authentication unit 19e or the authentication unit 31c has performed authentication (steps S12 and S14) during operation of the power conversion device 15 (step S10), the termination of this communication is normal by the determination units 19b and 31c. It is determined that the process has been completed, and the process proceeds to step S18. The determination result of the determination unit 31e is output to the drive control unit 31d, and the determination result of the determination unit 19b is output to the power conversion control unit 19c.

  In step S18, since the determination results of the determination units 19b and 31e are normal completion, the drive control unit 31d permits power supply from the storage battery 25 to the motor 23, and the power conversion control unit 19c The stop of the converter 15 is maintained. Thereby, the person 21 can start the vehicle 7.

  On the other hand, in step S19, when the cable 3 is pulled out from the power management device 5 and / or the vehicle 7 and the communication between the power management device 5 and the vehicle 7 is finished, the termination is performed by the determination units 19b and 31e. It is determined whether or not the end is normal. In this case, since neither the authentication unit 19e nor the authentication unit 31c is authenticated while the power conversion device 15 is in operation, the determination units 19b and 31e determine that this end is not a normal end, and the process proceeds to step S20. .

  And in step S20, since the determination result of the determination part 19b is not normal completion | finish, the power conversion control part 19c stops the power converter device 15 and stops electric power supply. Thereby, an electric shock due to the cable 3 being pulled out or disconnected from the power management device 5 and / or the vehicle 7 is prevented.

  In step S21, since the determination result of the determination unit 31e is not a normal end, the drive control unit 31d maintains prohibition of power supply from the storage battery 25 to the motor 23 (that is, maintains prohibition of starting of the vehicle 7). . Thus, the user can sense that some abnormality has occurred. Moreover, theft of the vehicle 7 is prevented by maintaining the prohibition of the start of the vehicle 7. Then, the process ends.

  According to the power management system 1 configured as described above, the cable 3 is not terminated normally (that is, when the cable 3 is pulled out or disconnected improperly, or the lock mechanisms 3e and 3f are broken). Since the power supply is stopped (step S20), electric shock can be prevented.

  Whether or not the end of communication is a normal end is determined depending on whether or not the end of communication is an end through an authentication processing procedure by the authentication unit 19e or 31c while the power conversion device 15 is operating. Therefore (steps S11 to S14), the determination can be performed correctly.

  Moreover, since authentication information can be input from either the vehicle 7 or the power management apparatus 5 (steps S11 to S14), it is convenient.

  Moreover, since the memory | storage part 31b is arrange | positioned at the vehicle 7, 1st authentication information and 2nd authentication information can be set uniquely for every vehicle 7. FIG.

  In a state where the vehicle 7 is supplied with power from the power management device 5 via the cable 3, the start drive of the vehicle 7 is prohibited (step S <b> 9). The vehicle 7 can be prevented from starting.

  Further, when the communication is not normally terminated (that is, when the cable 3 is illegally pulled out or disconnected), the prohibition of driving the motor 23 is maintained (step S21), so that the vehicle 7 can be prevented from being stolen. .

  If the end of communication is a normal end (that is, when the cable 3 is pulled out with a correct processing procedure), the drive of the motor 23 is permitted (step S18), and the vehicle can be started.

  Further, since the lock mechanisms 3e and 3f are unlocked after the power converter 15 is stopped (step S16), an electric shock can be prevented.

  In this embodiment, when the lock mechanisms 3e and 3f are locked (step S8), the drive control unit 31d prohibits the start of the vehicle 7 (step S9), but the verification by the authentication unit 19e matches. (Step S5), or when the power conversion device 15 is activated (step S10), the drive control unit 31d may prohibit the vehicle 7 from starting.

  In this embodiment, the case where the two input receiving units 13 and 27 are provided has been described. However, one of the input receiving units 13 and 27 may be omitted. This is because if at least one of the input receiving units 13 and 27 is present, authentication information can be input.

  In this embodiment, in steps S3 to S5, authentication is performed using only the authentication information input to the input receiving unit 13, but instead of doing so, the authentication input to the input receiving unit 27 is performed. Authentication may be performed using only the information, and authentication using the authentication information input to the input reception unit 13 and authentication information input to the input reception unit 27 are used as in steps S11 to S14. It may be combined with authentication.

  In this embodiment, in steps S11 to S14, authentication information input to the input receiving unit 13 (ie, authentication by the authentication unit 19e) and authentication information input to the input receiving unit 27 (ie, authentication) are authenticated. 1), the power conversion device 15 is stopped and the lock mechanisms 3e and 3f are unlocked. Only when both of them are authenticated, the power conversion device 15 is stopped and The lock mechanisms 3e and 3f may be unlocked.
