  When charging and discharging the storage battery of the electric vehicle, the user can stop charging and discharging, for example, by pressing a stop button provided on the charge and discharge device. However, the stop button can also be pressed by a third party other than the user. Therefore, when only the stop button is provided in the charge / discharge device as a mechanism for accepting the charge / discharge stop operation, charge / discharge is stopped against the user's intention or the connector is locked due to mischief by a third party. It may be released.

  Also, in some cases, the user may be able to stop charging / discharging by, for example, holding a card held by the user over the touch panel of the charging / discharging device or inputting a password held by the user. In this case, the card is issued in advance by an administrator such as a trader who charges for charge and discharge. Also, the password is issued in advance by the administrator, or preset by the user.

  Therefore, the user needs to manage the card or needs to remember the password. In addition, the administrator needs time and effort to construct and manage the server.

  Patent Document 1 does not disclose any specific method for starting and stopping charging. Further, in the vehicle charging system of Patent Document 1, an operation is performed using a key distributed in advance to the user in order to use the mechanical parking facility, but charging is not started or stopped by the operation.

  Further, Patent Document 2 only discloses an example of use of a key used for a coin locker, and Patent Document 2 does not disclose the charge / discharge of the vehicle at all.

  An object of one embodiment of the present invention is to realize a charge and discharge device that can prevent charge and discharge from being stopped against the user's intention with a simple configuration.

And an operation unit that receives the charge / discharge stop operation on condition that the loan member is returned to the main body, the connector is locked during the charge / discharge, and the operation is performed. And a connector lock unit that unlocks the connector when the unit receives the stop operation.

  According to said structure, a loan member is a member which will be in the state which can be removed from the main body of a charging / discharging apparatus, when charging / discharging is performed. Further, when the operation unit receives the stop operation on condition that the loan member is returned to the main body, the lock of the connector is released. That is, when the loanable member in the removable state is taken out by, for example, the user during charging / discharging, charging / discharging is stopped or the connector is unlocked until the loaned member is returned. There is no such thing. Therefore, it is possible to prevent a third party other than the user from stopping charging / discharging halfway and releasing the lock of the connector after stopping by, for example, a mischief.

  In addition, the use of the lending member in order to prevent the halfway stop of charging and discharging does not cause the trouble of the user or the manager as described above.

  That is, according to the charge / discharge device, it is possible to prevent the charge / discharge from being stopped against the user's intention with a simple configuration.

  Furthermore, the charge / discharge device according to one aspect of the present invention, in a state where the connector is not connected to the charging port, when the lent member is in a removable state, informs that the removable state The notification unit may be provided.

  The lending member is in a removable state during charging and discharging. Therefore, when the lending member is in a removable state, it can be inferred that the user has an intention to perform charging and discharging. Therefore, even if the lending member is in the removable state, if the connector is not connected to the charging port, it can be said that the charge / discharge device is in a state contrary to the user's intention.

  According to the above configuration, in the state where the connector is not connected to the charging port, when the lending member is in the removable state, it is possible to notify that effect. Therefore, it is possible to urge the user who is willing to perform charging and discharging to connect the connector to the charging port. In addition, it is possible to notify the user that the third party is in a removable state.

  The charge / discharge device according to an aspect of the present invention further includes a password processing unit that issues a password each time the charge / discharge is performed and performs authentication of the password, and the password processing unit succeeds in the authentication. In this case, the stop operation may be received, and the connector lock unit may release the lock of the connector when the password processing unit receives the stop operation.

  According to the above configuration, the connector lock unit releases the lock of the connector when the password processing unit accepts the stop operation as a result of the successful authentication of the password. In other words, the connector lock unit receives a two-step stop operation when the operation unit receives a stop operation due to the return of the lent member and when the password processing unit receives the stop operation due to the successful password authentication. , Unlock the connector.

  Therefore, as compared with the configuration in which the lock of the connector is released when the operation unit receives the stop operation by the return of the lent member, the release of the lock by a third party not intended by the user can be more firmly prevented. Therefore, the safety (security) concerning charge and discharge can be further improved.

  Furthermore, in the charge / discharge device according to one aspect of the present invention, the lending member is a key, and the operation unit is a mechanism capable of switching the position of the key in the held state. The key may be removed only when the charging / discharging start position is switched to start charging / discharging.

  According to the above configuration, the charge / discharge device enables removal of the key only when the user intends to start charge / discharge. Therefore, it is possible to prevent the charging / discharging from being stopped against the user's intention during charging / discharging by removing the key during charging / discharging. In addition, when the position of the key is not at the charge / discharge start position, the key can not be removed. Therefore, theft of the key can be prevented.

  In addition, since the key and the mechanism are provided, the switching of the position of the key allows the operation unit to receive a charge / discharge start operation or a stop operation. Therefore, since the start button and the start button become unnecessary, the charge and discharge device can be simplified.

  Furthermore, in the charge / discharge device according to one aspect of the present invention, the operation unit may receive the stop operation when the position of the key is switched to the charge / discharge stop position for stopping the charge / discharge. I do not care.

  According to the above configuration, the lock of the connector can be released by accepting the stop operation when the charge / discharge stop position is switched.

  Furthermore, in the charge / discharge device according to one aspect of the present invention, when the position of the key is switched to the charge / discharge start position and the connector is connected to the charge port, the operation unit When the discharge start operation is received, the connector lock unit may lock the connector when the operation unit receives the start operation.

  According to the above configuration, the connector can be locked while accepting the start operation in a state where charging and discharging can be reliably started.

  Furthermore, in the charge / discharge device according to one aspect of the present invention, the power supply control unit controls switching of the power on / off of the charge / discharge device, and the power control unit When the power is switched to the power off position for turning off the power, the power may be turned off.

  According to the above configuration, the power can be turned off using the key. Therefore, the standby power of the charge / discharge device when not in use can be reduced.

  Furthermore, in order to solve said subject, the charging / discharging apparatus which concerns on 1 aspect of this invention is equipped with the connector connected to the charge port of the vehicle carrying a storage battery, and connecting the said connector to the said charge port A charge / discharge device for charging / discharging the storage battery, wherein the operation unit receives the start / stop operation of the charge / discharge, and issues the member to be issued to which identification information is added each time the charge / discharge is performed An issuing unit, and a reading unit capable of accepting the stop operation by the operation unit by reading the identification information of the issued member issued by the issuing unit; and locking the connector during charging and discharging. And a connector lock unit that unlocks the connector when the operation unit receives the stop operation.

  According to the above configuration, the member to be issued with identification information is issued each time charging and discharging are performed, and the identification information given to the member to be issued is read, whereby the stop operation by the operation unit is received. It becomes possible. In addition, when the operation unit receives the stop operation, the lock of the connector is released.

  That is, it becomes possible for the user to hold the issued member to be issued during charging and discharging. Therefore, charging / discharging is not stopped or the lock of the connector is not released until the reading unit reads the identification information given to the held member held by the user. Therefore, it is possible to prevent a third party from stopping charging / discharging halfway and releasing the lock of the connector after stopping by, for example, a mischief.

  Moreover, in order to prevent the halfway stop of charging / discharging, the effort of a user or an administrator which was mentioned above does not generate | occur | produce by using the to-be-issued member to which identification information was attached.

  That is, according to the charge / discharge device, it is possible to prevent the charge / discharge from being stopped against the user's intention with a simple configuration.

FIG. 1 is a view showing a configuration example of a charge and discharge system. As shown in FIG. 1, the charge / discharge system includes a charge / discharge device 1 and an electric vehicle 100 connectable to the charge / discharge device 1.

  The charge and discharge device 1 controls charge and discharge of the on-board storage battery 102 mounted on the electric vehicle 100. The charge and discharge device 1 is installed, for example, in a public facility, a facility of a private enterprise, or a parking lot of an apartment, and can be used by an unspecified number of persons. Moreover, the charge / discharge device 1 may be installed, for example, in a parking lot of a general house. As a public facility or a facility of a private enterprise, for example, a service area of a highway or a commercial complex facility such as a shopping mall can be mentioned.

  The electrically powered vehicle 100 is equipped with a large-capacity on-board storage battery 102 for storing power used during traveling. Electric powered vehicle 100 includes a storage battery for driving, and includes various vehicles capable of traveling by converting the power in the storage battery into a driving force. Examples of the vehicle include an electric vehicle (EV), a plug-in hybrid vehicle (PHV), a plug-in hybrid electric vehicle (PHEV), and a fuel cell vehicle (FCV). It can be mentioned.

[Configuration of charge and discharge device]
The charge and discharge device 1 includes a charge and discharge device main body 2 (main body), a connector 3 and a cable 4.

  The charge / discharge device main body 2 controls charge / discharge of the in-vehicle storage battery 102. The charge / discharge device main body 2 is, for example, based on (1) user's input operation, (2) an instruction from the electric vehicle 100, or (3) an instruction from a controller (not shown) connectable via a network. Charging and discharging the on-vehicle storage battery 102 are performed. That is, the charge / discharge device main body 2 performs start, stop, or switching of the charge operation and the discharge operation based on any of these instructions. Examples of the controller include an EMS (Energy Management System) controller.

  In addition, the charge / discharge device main body 2 may be connected so as to be able to exchange power with a commercial power system or an electronic device (neither of which is shown). In this case, the charge / discharge device main body 2 can perform a self-sustaining operation to supply the power in the on-board storage battery 102 to the electronic device when the commercial power grid fails. Moreover, it is also possible to perform grid-connected operation in which the power in the on-board storage battery 102 is supplied to the electronic device in addition to the power from the commercial power system at the time of non-power failure.

  Further, the charge / discharge device main body 2 may request the user to pay (charge) the charge for the use of the charge / discharge device 1. In this case, for example, a charge (unit price) is set in advance based on the charge amount or charge time. The charge / discharge device main body 2 requests the user to pay the charge based on the charge amount or the charge time after inputting (selecting) the charge amount or the charge time when using the charge / discharge device 1. The charge / discharge device body 2 permits the use of the charge / discharge device 1 when the payment of the charge is completed. That is, in this case, the payment of the charge is made (in advance) before charging and discharging.

  The payment of the charge may be after the charge / discharge by the charge / discharge device 1 is completed (ex post). In this case, even if the position of the key 51 is switched to the charge / discharge stop position (for example, the “stop” position) after the key 51 (rental member) is returned as described later, the charge / discharge device main body 2 The connector 3 is not unlocked unless it recognizes that the payment is completed.

  Further, the charge / discharge device 1 selects one charge information from the plurality of charge information by presenting a plurality of charge information (charge / discharge amount corresponding to the charge information) based on the battery information on the on-board storage battery 102. You do not mind. In this case, for example, when the connector 3 is connected to the charging port 101 of the electric vehicle 100, the charge / discharge device main body 2 displays data indicating the remaining battery capacity (or battery charging rate) of the on-board storage battery 102 and the total battery capacity. , Acquired from the electric vehicle 100 as battery information. Charge / discharge device main body 2 is a charge for reaching the predetermined charge rate from the current charge rate of in-vehicle storage battery 102, based on the acquired battery information and a unit price preset based on the charge amount or charge time, or The charge etc. which concern on charging / discharging of predetermined time are calculated, and the calculated charge is shown to a user. The charge / discharge device main body 2 is, for example, a plurality of “charge up to 80% of battery charge = ¥¥”, “charge up to full charge = ¥¥”, and “● charge of time = 時間 ¥”. Present rate information. When one piece of charge information is selected by the user, the charge / discharge device main body 2 performs the charge / discharge indicated by the charge information.

  The payment of the charge based on the charge information may be before or after charging and discharging. Before charge / discharge, the charge / discharge device body 2 permits the use of the charge / discharge device 1 when the payment of the charge based on the charge information is completed. In this case, the lock of the connector 3 may be released by switching the position of the key 51 to the charge / discharge stop position after the key 51 is returned. On the other hand, if it is after the fact, the charge / discharge device main body 2 does not unlock the connector 3 unless it recognizes the completion of the payment of the charge.

  In the current charge and discharge system, membership registration (pre-registration) is performed, and use of the charge and discharge system is permitted by paying a fixed membership fee every month. In this case, in order to use the charge and discharge system, it takes time and effort to register as a member. On the other hand, in the above case, the charge / discharge device 1 requests payment of the charge each time the charge / discharge device 1 is used. The user can use the charge / discharge device 1 without generating the trouble of member registration. That is, anyone can use the charge / discharge device 1 if only the charge is paid. Further, since the charge setting is performed based on the charge amount or the charge time, the user only has to pay the charge according to the charge amount or the charge time when using the charge / discharge device 1.

  In addition, in the charge / discharge device 1 which can be used without member registration, payment (settlement) of the charge is performed by, for example, cash, a credit card, or an IC (Integrated Circuit) card (eg, traffic IC card).

  The connector 3 is connected to the charging port 101 of the electric vehicle 100. The charge and discharge device 1 can charge and discharge the on-vehicle storage battery 102 by connecting the connector 3 to the charge port 101. The connector 3 includes a connector lock portion 31 which is a mechanism for locking the charging port 101 and preventing the charging port 101 from being detached at the time of charging and discharging.

In addition, the charge and discharge circuit 10 takes electric power from the on-board storage battery 102 and supplies the power to the storage battery provided inside or to the outside (discharge operation).

  In the state where the connector 3 is not connected to the charging port 101, the notification unit 20 notifies that the key 51 can be removed if the key 51 described later can be removed. Specifically, when notification unit 20 is in a state where key 51 can be removed from key switch 50 when connector 3 is not connected to charging port 101, notification unit 20 can be removed. To inform

  The notification unit 20 is a speaker that emits a warning sound when the above-mentioned state is reached, or verbalizes and notifies the above-mentioned notification content. Not only this but the alerting | reporting part 20 may be a light emitting diode which lights (or blinks) when it will be in the said state, and may be a display part which displays the above-mentioned alerting | reporting content. In the latter case, the touch panel 40 may function as the notification unit 20.

  The power supply 30 supplies power to each part of the charge and discharge device 1. The touch panel 40 receives various user's input operations and performs various displays related to charging and discharging.

  The key switch 50 is an operation unit that receives a charging / discharging start operation or a stop operation by the user. In the present embodiment, the key switch 50 is a mechanism capable of holding the key 51 and capable of switching the position of the held key 51.

  Specifically, the key switch 50 is a mechanism capable of rotating the inserted key 51, and the start or stop of charging / discharging according to the position of the key switch 50 at which the key 51 is temporarily fixed. Controllable. Further, the key switch 50 may be capable of controlling the switching of the power supply 30 on or off according to the position. The mechanism of the key switch 50 can use a known key switch.

  FIG. 2 is a view showing a specific example of the key switch 50. As shown in FIG. FIG. 2 (a) shows an example of a two-position switch 50a in which the key 51 is temporarily fixed at two positions, and FIGS. 2 (b) and 2 (c) show the keys 51 temporarily at three positions. An example of 3 position switches 50b and 50c fixed in a fixed manner is shown, respectively.

  The two-position switch 50a is capable of switching between start and stop of charge and discharge. As shown in FIG. 2A, the two-position switch 50a has, as the above-mentioned positions, an "operation" position for starting charging and discharging and a "stop" position for stopping charging and discharging. In the "stop" position, removal of the key 51 is not possible, and in the "operation" position, removal of the key 51 is possible.

  The three-position switch 50 b is a power supply switching type switch that can switch on and off the power supply 30 in addition to switching between start and stop of charge and discharge. As the position shown in FIG. 2B, the three-position switch 50b is used to turn on the power supply 30 and the "power off" position (power off position) for turning off the power supply 30, or It has a "power on / stop" position for stopping charging and discharging, and an "operation" position for starting charging and discharging. In the “power off” position and the “power on / off” position, removal of the key 51 is not possible, and in the “operation” position, removal of the key 51 is possible.

  The three-position switch 50c is a charge / discharge switching type switch that can select start of charge or discharge in addition to switching between start and stop of charge / discharge. As shown in FIG. 2C, the three-position switch 50b starts the "charge" position for starting charging, the "stop" position for stopping charging / discharging, and the discharge as the above-mentioned position, as shown in (c) of FIG. And a "discharge" position. In the "stop" position, removal of the key 51 is not possible, and in the "charge" position or the "discharge" position, removal of the key 51 is possible.

Thus, the key switch 50

(2) It has at least a "stop" position or a "power on / stop" position that functions as a charge / discharge stop position that can receive a charge / discharge stop operation. When the key 51 is in the charge / discharge stop position, the key 51 is in a mounted state (non-extractable state), and can not be removed for the first time when the charge / discharge start position is reached. Become.

  That is, the key 51 is a member (hard key) in a removable state from the charge / discharge device main body 2 (specifically, the key switch 50) when charge / discharge of the in-vehicle storage battery 102 is performed (at least during charge / discharge). ). Then, the key switch 50 makes it possible to remove and insert the key 51 only when the position of the key 51 is switched to the charge and discharge start position.

  In addition, when the position of the key 51 is switched to the charge / discharge start position and the connector 3 is connected to the charge port 101, the key switch 50 receives the charge / discharge start operation. And the connector lock part 31 mentioned above locks the connector 3 when the key switch 50 receives start operation. Thus, the connector lock portion 31 can lock the connector 3 during charging and discharging of the in-vehicle storage battery 102.

  The key 51 is a member that needs to be returned to the charge / discharge device 2 (specifically, the key switch 50) when charging / discharging is stopped, and the key switch 50 has the key 51 as the key switch 50. A charge / discharge stop operation is accepted on the condition that it is returned to. In the present embodiment, after the key 51 is extracted at the charge / discharge start position, the key switch 50 is inserted again to the charge / discharge start position, and the position of the key 51 is switched to the charge / discharge stop position. Accept the charge / discharge stop operation. Then, the connector lock unit 31 unlocks the connector 3 when the key switch 50 receives the stop operation.

  In the case of the two-position switch 50a shown in (a) of FIG. 2 or the three-position switch 50b shown in (b) of FIG. 2, the charge / discharge device main body 2 operates in a preset operation mode (charge mode or discharge mode Charge and discharge according to. For example, when the operation mode is set to the charge mode, the charge / discharge device main body 2 charges the on-vehicle storage battery 102. However, when the position of the key 51 is at the “stop” position or the “power off / stop” position, the operation mode may be switched according to the input operation or the like by the user.

  The emergency stop button 60 is used by the user when an emergency such as a malfunction occurs in the charge / discharge device 1 or the electric vehicle 100 connected to the charge / discharge device 1 during charging / discharging of the in-vehicle storage battery 102. It is for forcibly stopping charging and discharging.

  The control unit 70 controls the charge / discharge device 1 in an integrated manner, and mainly, the charge / discharge control unit 71, the notification control unit 72, the power supply control unit 73, the operation determination unit 74, the connection determination unit 75, and connector control A unit 76 is provided.

  The charge / discharge control unit 71 controls the charge / discharge of the in-vehicle storage battery 102 by controlling the charge / discharge circuit 10 based on an input operation or the like by the user. The charge and discharge control unit 71 may also display on the touch panel 40 that charging and discharging are in progress. Instead of the display on the touch panel 40, for example, a light emitting diode may be provided and the light emitting diode may be lit (flickered).

  The notification control unit 72 controls the notification unit 20 to notify that the key 51 can be removed (that is, the key 51 can be removed). Note that the notification control unit 72 may notify the administrator of the charge / discharge system (e.g., a trader who charges for charge / discharge) instead of or in addition to the notification from the notification unit 20.

  The power control unit 73 controls switching of the power supply 30 on and off based on an input operation of power on or off on the touch panel 40 or an input operation on the key switch 50. When the key switch 50 is, for example, the 3-position switch 50b shown in FIG. 2B, the power control unit 73 turns off the power supply 30 when the position of the key 51 is switched to the "power off" position. Do.

  If the power supply 30 is switched to the “power off” position during charge and discharge and the power supply 30 is turned off immediately after that, problems such as occurrence of problems in the charge and discharge device 1 or the electric vehicle 100 may occur. Therefore, when the position of the key 51 is switched to the “power off” position, the power control unit 73 may turn off the power supply 30 after performing a predetermined charge / discharge stop operation, which may cause the above problem. It can be reduced.

  The operation determination unit 74 determines the position of the key 51 inserted into the key switch 50 to determine what kind of operation the input operation received by the key switch 50 is.

  The connection determination unit 75 determines whether the connector 3 is connected to the charging port 101.

Specifically, the connection determination unit 75

(A-2) When a predetermined potential change occurs in the first work start / stop line which is a part of the analog line
(A-3) when a current having a predetermined current value flows to the ground line which is a part of the analog line, or
(A-4) When a voltage having a predetermined voltage value is applied between the charge / discharge connector 12 V, which is a part of the analog line, and the ground line,
It is determined whether the connector 3 is connected to the charging port 101 or not.

  The charge / discharge connector connection confirmation line is a signal line to which the power supply voltage (12 V) on the electric vehicle 100 side is supplied when the connector 3 is connected to the charge port 101. The first work start and stop line is a signal line for transmitting the start potential indicating the start of the charge and discharge preparation operation to the electrically powered vehicle 100. The charge / discharge connector 12V is a signal line to which a voltage is applied from an auxiliary storage battery (not shown) provided in the electric vehicle 100. The ground line is a signal line grounded on the electric vehicle 100 side when the connector 3 is connected to the charge port 101.

  Further, a relay (d1) which is turned on to transmit the start potential is disposed on the first work start / stop line. When the relay (d1) is turned on, the charge and discharge preparation process is performed according to the sequence defined in the standard. Specifically, after the relay (d1) is turned on, electrically powered vehicle 100 transmits predetermined information to charge / discharge device 1 by CAN communication. In the case of (b), the connection determination unit 75 determines that the connector 3 is connected to the charging port 101 by determining that CAN communication has been started when predetermined information is received from the electrically powered vehicle 100. It should be noted that the present invention is not limited to the above case, and it may be determined that the connector 3 is connected to the charging port 101 when transmission and reception of signals with the electric vehicle 100 is started via the CAN signal line.

  In addition, the above-mentioned specific example regarding (a) and (b) is an example to the last. That is, the connection determination unit 75 determines whether the connector 3 is connected to the charging port 101 by a method in accordance with various standards regarding charging and discharging of the electric powered vehicle 100.

  The connector control unit 76 controls the connector lock unit 31 to lock the connector 3 with the charging port 101 or to release the lock.

[Flow of treatment in charge / discharge device]
Next, an example of various processes of the charge and discharge device 1 will be described with reference to FIGS. 3 to 5. 3 to 5 are flowcharts showing an example of processing of the charge / discharge device 1. At the start of each process, the key 51 is inserted into the key switch 50, and the position of the key 51 is in the "stop" position or the "power off" position. That is, the key 51 can not be removed from the key switch 50. Also, the connector 3 is not connected to the charging port 101.

<Processing example in case of 2 position switch>
First, an example of processing of the charge / discharge device 1 in the case where the two-position switch 50a (see FIG. 2A) is provided as the key switch 50 will be described using FIG. In the process of FIG. 3, it is assumed that the power supply 30 is turned on.

  First, the operation determination unit 74 determines whether the position of the key 51 has been switched from the “stop” position to the “drive” position (S1). If it is determined that the switch has been switched to the “drive” position (YES in S1), the connection determination unit 75 determines whether the connector 3 is inserted into the charging port 101 (S2). Thus, the user can remove the key 51 from the two-position switch 50 a by switching the position of the key 51 to the “operation” position. In the case where S1 is NO, the operation determination unit 74 continues the process of S1.

  When the connector 3 is not inserted into the charging port 101 (NO in S2), the notification control unit 72 controls the notification unit 20 to emit a warning sound (S3). In this state, the operation determination unit 74 determines whether the position of the key 51 has been switched from the "drive" position to the "stop" position (S4). If it is determined that the switch has been made to the “stop” position (YES in S4), the notification control unit 72 stops the warning sound, and returns to the process of S1. On the other hand, when it is not switched to the "stop" position (NO in S4), the process returns to S2.

  That is, when the position of the key is in the “operation” position, the notification control unit 72 continues to emit a warning sound until the connector 3 is inserted into the charging port 101. Accordingly, it is possible to urge the user who has the intention to charge and discharge the on-board storage battery 102 to connect the connector 3 to the charging port 101. In addition, it is possible to notify the user that it is possible to take out by a third party.

  If it is determined that the connector 3 is inserted into the charging port 101 (YES in S2), if a warning sound is issued, the notification control unit 72 stops the warning sound (S6). In addition, since the position of the key 51 is the “operation” position and the connector 3 is connected to the charging port 101, the connector control unit 76 locks the connector 3 by controlling the connector lock portion 31 ( S7). After the connector 3 is locked, the charge / discharge control unit 71 controls the charge / discharge circuit 10 to start charging / discharging the in-vehicle storage battery 102 (S8).

  During charge and discharge, the operation determination unit 74 determines whether the position of the key 51 has been switched from the "drive" position to the "stop" position (S9). If it is determined that the position has been switched to the “stop” position (YES in S9), the charge / discharge control unit 71 stops charging / discharging of the in-vehicle storage battery 102 (S11).

  In addition, during charge and discharge, the charge and discharge control unit 71 determines whether a predetermined stop condition is satisfied (S10). If the charge / discharge control unit 71 determines that the predetermined stop condition is satisfied (YES in S10) even if the position of the key 51 remains the "drive" position (NO in S9), the on-vehicle storage battery 102 is detected. Charging and discharging are stopped (S11). If the predetermined stop condition is not satisfied (NO in S10), the process returns to S9. Note that, as the predetermined stop condition, for example, reaching of a preset end capacity of charge and discharge, or a stop instruction from the outside (eg, the electric vehicle 100) may be mentioned.

  After the charging / discharging control unit 71 stops charging / discharging, the operation determining unit 74 determines whether the position of the key 51 is switched from the “drive” position to the “stop” position (S12). When switching to the "stop" position at this time, or when switching to the "stop" position in S9 and charging / discharging is stopped (YES in S12), the connector control unit 76 is defined by the standard. The lock of the connector 3 is released in accordance with a predetermined sequence (S13).

  On the other hand, when the switching to the "stop" position is not performed, that is, when the charging and discharging are stopped without being switched to the "stop" position in S9 (NO in S12), the operation determination unit 74 determines the "stop" position. Wait until it is switched to At this time, the notification control unit 72 may prompt the user to perform the insertion and the switching by notifying the insertion of the key 51 to the two-position switch 50a and the switching to the “stop” position.

  In this manner, if the user switches the position of the key 51 to the "operation" position and then removes the key 51, the charge / discharge device 1 will continue unless the key 51 is reinserted and switched to the "stop" position. Alternatively, charging and discharging are not stopped unless the predetermined stop conditions are satisfied. Therefore, it is possible to prevent a third party from stopping charging / discharging halfway, for example, due to mischief.

  Also, the lock of the connector 3 is not released unless the key 51 is reinserted and switched to the "stop" position. Therefore, unlocking of the connector 3 by a third party can be prevented.

  In addition, it is possible to prevent the third party from stopping charging and discharging and unlocking the connector 3 without using a password or the like issued in advance by member registration. Therefore, for the purpose of the prevention, it is not necessary for the user to take care of memorizing the password. In addition, the mechanism for authenticating the password does not require network connection with the server that manages the members, so the charge / discharge system can be simplified. Furthermore, the above prevention can be achieved without providing the start button capable of accepting the start operation and the stop button capable of accepting the stop operation. That is, the above-described prevention can be achieved with a simple configuration.

  Further, (1) only when the position of the key 51 is switched to the “operation” position, the key 51 can be removed. (2) In this state, when the connector 3 is not connected to the charging port 101, notification by the notification unit 20 is performed. Furthermore, the lock of the connector 3 is not released unless (3) the key 51 is reinserted and switched to the "stop" position. As long as the connector 3 is not unlocked, the electric vehicle 100 remains connected to the charge / discharge device 1. Therefore, the theft of the key 51 can be prevented by the configurations (1) to (3).

  Further, by using the charge / discharge device 1 by providing the key switch 50 and the key 51, the charge / discharge device 1 performs member registration, carrying of cards etc. distributed by member registration, and / or a portable information terminal No need to download and operate the application. Therefore, anyone can use the charge / discharge device 1. In such a charge / discharge device 1, it is useful to be able to prevent the stop of charge / discharge and the unlocking of the connector 3 by a third party.

<Processing Example for 3-Position Switch (Power Supply Switching Type)>
Next, an example of processing of the charge / discharge device 1 in the case where the three-position switch 50 b (see (b) in FIG. 2) is provided as the key switch 50 will be described using FIG. 4. At the start of the process of FIG. 4, the power supply 30 is assumed to be off.

  First, in the 3-position switch 50b, when the position of the key 51 is switched from the "power off" position to the "power on / off" position, the power control unit 73 turns on the power supply 30 (S21). The degree to which the function of the operation determination unit 74 (determination of switching of the position of the key 51) and the function of the power control unit 73 (switching from off to on of the power supply 30) can be performed even when the power supply 30 is off. Is supplied from the power supply 30 to the control unit 70 (specifically, a CPU (Central Processing Unit) that executes the function of the control unit 70).

  Thereafter, the operation determination unit 74 determines whether or not the position of the key 51 has been switched from the “power on / stop” position to the “power off” position (S22). If it is determined that the power is switched to the “power off” position (YES in S22), the power control unit 73 turns off the power 30 (S23). On the other hand, when the operation determining unit 74 has not been switched to the “power off” position (NO in S22), the operation determining unit 74 determines whether the “power on / stop” position has been switched to the “driving” position (S24). If it is determined that the switch to the “drive” position has been made (YES in S24), the connection determination unit 75 determines whether the connector 3 is inserted into the charging port 101 (S25). Thus, the user can remove the key 51 from the three-position switch 50b by switching the position of the key 51 to the "operation" position. If NO in S24, the operation determination unit 74 continues the processing in S22 and S24.

  About the process when the connector 3 is not inserted in the charging port 101 (NO in S25), the same process as S3 to S5 in FIG. 3 is performed (S26 to S28). About the process when the connector 3 is inserted in the charging port 101 (YES in S25), the same process as S6 to S13 is performed (S29 to S36). However, in the processing of S26 to S36, the "stop" position in S3 to S13 is replaced with the "power on / stop" position. After the connector 3 is unlocked at S36, the process returns to S22.

  As described above, by providing the key switch 50 with the “power on / off” position and the “power off” position, switching control of the power supply 30 on and off can be performed. Then, when the connector 3 is not connected to the charging port 101, the position of the key 51 can be switched to the “power off” position, so standby power of the charging / discharging device 1 when not in use can be suppressed. Also in the present process, the effects of the process of FIG. 3 related to the two-position switch 50a are achieved.

<Processing Example for 3-Position Switch (Charge / Discharge Switching Type)>
Next, an example of the process of the charge / discharge device 1 in the case where the three-position switch 50c (see (c) in FIG. 2) is provided as the key switch 50 will be described using FIG. In the process of FIG. 5, it is assumed that the power supply 30 is turned on.

  First, the operation determination unit 74 determines whether the position of the key 51 has been switched from the “stop” position to the “charge” position or the “discharge” position (S41). If it is determined that the switch has been switched to the "charge" position or the "discharge" position (YES in S41), the connection determination unit 75 determines whether the connector 3 is inserted into the charge port 101 (S42). Thus, the user can remove the key 51 from the three-position switch 50 c by switching the position of the key 51 to the “charge” position or the “discharge” position. If NO in S41, the operation determination unit 74 continues the process of S41.

  About the process when the connector 3 is not inserted in the charging port 101 (NO in S42), the same process as S3 to S5 in FIG. 3 is performed (S43 to S45).

  If it is determined that the connector 3 is inserted into the charging port 101 (YES in S42), if a warning sound is issued, the notification control unit 72 stops the warning sound (S46). Further, since the position of the key 51 is the "charge" position or the "discharge" position, and the connector 3 is connected to the charge port 101, the connector control section 76 controls the connector lock section 31 to thereby control the connector Lock 3 (S47).

  Next, after the connector 3 is locked, the operation determination unit 74 determines whether the position of the key 51 determined in S41 is the “charge” position (S48). When it is determined that the position of the key 51 is the "charge" position (YES in S48), the charge / discharge control unit 71 controls the charge / discharge circuit 10 to start charging the in-vehicle storage battery 102 (S49) . On the other hand, when it is determined that the position of the key 51 is the “discharge” position (NO in S48), the charge / discharge control unit 71 starts discharging the in-vehicle storage battery 102 (S52).

  During the charge and discharge, the same processing as S9 to S11 is performed. That is, the operation determination unit 74 determines whether the position of the key 51 is switched from the “charge” position or the “discharge” position to the “stop” position (S50 or S53). If it is determined that the position has been switched to the “stop” position (YES in S50 or YES in S53), the charge / discharge control unit 71 stops charging or discharging the in-vehicle storage battery 102 (S55).

  Further, the charge / discharge control unit 71 determines whether or not a predetermined stop condition is satisfied (S51 or S54). Even when the position of the key 51 remains at the "charge" position or the "discharge" position (NO at S50 or NO at S53), the charge / discharge control unit 71 determines that the predetermined stop condition is satisfied (S51) In the case of YES or YES in S54, charging or discharging of the on-board storage battery 102 is stopped (S51). If the predetermined stop condition is not satisfied (NO in S51 or NO in S54), the process returns to S50 or S53.

  Thereafter, the same processing as S12 and S13 of FIG. 3 is performed (S56 and S57). However, in the processes of S56 and S57, the "operation" position in S12 and S13 is read as the "charge" position or the "discharge" position.

  Thus, by providing the "charge" position and the "discharge" position on the key switch 50, the operation mode can be switched (selected) with a simple configuration such as changing the position of the key 51 without using the touch panel 40 or the like. It will be possible to do. Also in the present process, the effects of the process of FIG. 3 related to the two-position switch 50a are achieved.

[Modification 1: Modification of Lending Member]
In the above, the case where the key switch 50 is provided as the operation unit and the lending member is the key 51 has been described. However, the configuration for preventing charge and discharge from being stopped against the user's intention is not limited to this. For example, the lending member may be realized by a card or a ticket which can be taken out by the user when charging and discharging are started.

(1) When the loaning member is a card When the lending member is a card, the operation unit enables removal of the card when accepting the start operation, and a card processing mechanism which makes removal of the card impossible otherwise. Is realized by The operation unit has an insertion slot into which a card is inserted, and receives a stop operation when the card is returned to the insertion slot. Moreover, in the case of this aspect, the start operation is accepted by the touch panel 40 or the start button (not shown). That is, the touch panel 40 or the start button also functions as the operation unit.

  For example, when the card is in a state in which the card can not be removed, the operation unit sets the card in a state in which the card can be removed when the start operation is received. Then, when control unit 70 determines that connector 3 is connected to charging port 101, control unit 70 locks connector 3 and then performs charging and discharging of in-vehicle storage battery 102.

  When the card is returned to the operation unit, the control unit 70 determines that the stop operation has been received, stops charging / discharging of the in-vehicle storage battery 102, and then releases the lock of the connector 3. In addition, when the controller 70 satisfies the predetermined stop condition and stops the charge and discharge, the controller 70 does not release the lock of the connector 3 until the card is returned.

  The touch panel 40 or a stop button (not shown) may accept a stop operation. In this case, the operation unit is realized by the touch panel 40, the start button or the stop button, and a card processing mechanism is provided separately from the operation unit. In addition, when the card is returned, the touch panel 40 or the stop button becomes ready to receive the stop operation.

(2) When the Lending Member is a Ticket When the lending member is a ticket, the operation unit is realized by a ticket issuing mechanism that issues a ticket when a start operation is received. The operation unit differs from the provided card in that it issues a new ticket (disposable ticket) each time it receives a start operation. Further, the operation unit has an insertion slot into which a ticket is inserted, and accepts a stop operation by returning the issued ticket to the insertion slot. Also in the case of this embodiment, the operation unit may be realized by the touch panel 40, the start button or the stop button, and a ticket issuing mechanism may be provided separately from the operation unit.

  For example, the operation unit issues a ticket upon accepting a start operation. Thereafter, when control unit 70 determines that connector 3 is connected to charging port 101, control unit 70 locks connector 3 and then performs charge and discharge on in-vehicle storage battery 102. The subsequent processing is the same as in the case where the lending member is a card.

[Modification 2: Configuration that allows insertion and removal determination]
In the above, the operation determination unit 74 determines in which position the position of the key 51 is located in the key switch 50, but the present invention is not limited thereto. The operation determination unit 74 may be configured to be able to determine the insertion and removal of the key 51. However, in this case, the key switch 50 needs to be a mechanism that enables the determination.

[Modification 3: Preventing leaving of removable key]
The key 51 can be removed from the key switch 50 by switching to the charge / discharge start position. Therefore, in this state, not only the user but also a third party can extract the key 51. In order to prevent removal of the key 51, for example, the notification control unit 72 may fail to remove the predetermined time after determining that the operation determination unit 74 has been switched to the charge / discharge start position. May be notified by a warning sound or the like.

  When the operation determination unit 74 is configured to determine whether the key 51 has been extracted, the key 51 is extracted after a predetermined time has elapsed since switching to the charge / discharge start position. If not, it may be informed that a failure to remove the key 51 has occurred.

[Modification 4: Other Modifications]
The charge and discharge device 1 may be a multi-type charge and discharge device including a plurality of connectors 3. In this case, the key switch 50 and the key 51 are provided for each connector 3. As a result, charging / discharging of a plurality of electric vehicles 100 can be performed by one charging / discharging device 1, and charging / discharging of each electric vehicle 100 is stopped against the user's intention with a simple configuration. It can prevent.

  In addition, the master key of the key 51 provided to the key switch 50 may be separately prepared and owned by the manager of the charge / discharge system. In this case, not only the user but also the administrator can control the start or stop of charging / discharging using the master key, and in turn the locking of the connector 3. As a result, it is possible to prevent the situation where the charge / discharge device 1 does not function due to the loss or theft of the key 51.

  In addition, the two-position switch 50a or the three-position switch 50c may be configured to be able to switch on and off the power supply 30. In this case, in the two-position switch 50a, the "drive" position functions as a position for switching the power supply 30 from off to on, and the "stop" position functions as a position for switching the power supply 30 from on to off. . Further, in the three-position switch 50c, the "charge" position or the "discharge" position functions as a position for switching the power supply 30 from off to on. And in the process of FIG.3 and FIG.5, while the power supply 30 is turned ON by switching to a "driving | working" position, a "charge" position, or a "discharge" position first, it switches to a "stop" position. Then, the power supply 30 is turned off.

Second Embodiment
Other embodiments of the present invention are described below.

[Configuration of charge and discharge device]
FIG. 6 is a view showing a configuration example of the charge and discharge device 1a. The charge / discharge device 1a of the present embodiment differs from the charge / discharge device 1 of the first embodiment in that the charge / discharge device main body 2a includes a control unit 70a as shown in FIG. Specifically, the control unit 70a differs from the charge and discharge device 1 of the first embodiment in that the control unit 70a includes a password processing unit 77 in addition to the components included in the control unit 70.

  The password processing unit 77 issues a password, and authenticates the password as to whether or not the issued password matches the password input by the user. Then, when it is determined that the password authentication is successful, the password processing unit 77 receives a charge / discharge stop operation.

  The password processing unit 77 issues a password each time charging and discharging are performed. The password is, for example, one for completing charging and discharging (specifically, a password for unlocking the connector 3). Also, the password processing unit 77 displays the issued password on the touch panel 40. The touch panel 40 displays the password issued by the password processing unit 77 and accepts an input operation of the password.

  In addition to the case where the key 51 is inserted into the key switch 50 and switched to the “stop” position or the “power on / stop” position while the connector 3 is locked, the connector control unit 76 also performs password authentication. When it succeeds, the lock of the connector 3 is released.

[Flow of processing in charge / discharge device (example of processing when double lock is possible)]
Next, an example of the process of the charge / discharge device 1a will be described with reference to FIG. FIG. 6 is a flowchart showing an example of processing of the charge / discharge device 1a. In this process, the case where a three-position switch 50c is provided as the key switch 50 will be described as an example. However, it will be appreciated that the same process is performed even with the two-position switch 50a or the three-position switch 50b according to the following description using FIG.

  Also, at the start of this process, the key 51 is inserted into the key switch 50, and the position of the key 51 is at the "stop" position. That is, the key 51 can not be removed from the key switch 50. Also, the connector 3 is not connected to the charging port 101.

  At the start of the process, the power supply 30 is off. Further, the three-position switch 50 c used in the present processing is configured to be able to switch on and off the power supply 30.

  As shown in FIG. 7, when the position of the key 51 is switched from the “stop” position to the “charge” position or the “discharge” position in the three-position switch 50 c, the power control unit 73 turns on the power supply 30. (S61). Thus, the user can remove the key 51 from the three-position switch 50 c by switching the position of the key 51 to the “charge” position or the “discharge” position.

  Thereafter, the operation determination unit 74 determines whether the position of the key 51 has been switched from the “charge” position or the “discharge” position to the “stop” position (S62). If it is determined that the position has been switched to the "stop" position (YES in S62), the power control unit 73 turns off the power supply 30 (S66). On the other hand, when it is not switched to the "stop" position (NO in S62), the connection determination unit 75 determines whether the connector 3 is inserted into the charging port 101 (S63).

  When the connector 3 is not inserted into the charging port 101 (NO in S63), the notification control unit 72 controls the notification unit 20 to emit a warning sound (S64). In this state, the operation determination unit 74 determines whether the position of the key 51 has been switched from the “charge” position or the “discharge” position to the “stop” position (S65). If it is determined that the position has been switched to the "stop" position (YES in S65), the notification control unit 72 stops the warning sound and turns off the power supply 30 (S66). On the other hand, when it is not switched to the "stop" position (NO in S65), the process returns to S63.

  If it is determined that the connector 3 is inserted into the charging port 101 (YES in S63), the password processing unit 77 issues a password (S67). At this time, when the alarm sound is notified, the notification control unit 72 stops the alarm sound. Thereafter, the connector control unit 76 locks the connector 3 by controlling the connector lock unit 31 (S68). After the connector 3 is locked, the charge / discharge control unit 71 controls the charge / discharge circuit 10 to start charging / discharging the in-vehicle storage battery 102 (S69). Specifically, the charge / discharge control unit 71 starts charging when the position of the key 51 is the “charge” position, and starts discharging when the position of the key 51 is the “discharge” position.

  During charge and discharge, the operation determination unit 74 determines whether the position of the key 51 has been switched from the "charge" position or the "discharge" position to the "stop" position (S70). If it is determined that the position has been switched to the "stop" position (YES in S70), the charge / discharge control unit 71 stops charging or discharging the in-vehicle storage battery 102 (S73).

  Further, the password processing unit 77 determines whether the issued password has been input (S71). Even if the position of the key 51 remains the "charge" position or the "discharge" position (NO in S70), if it is determined by the password processing unit 77 that the issued password has been input (if password authentication succeeds) ) (YES in S71), the charge / discharge control unit 71 stops charging or discharging the in-vehicle storage battery 102 (S73).

  Further, the charge / discharge control unit 71 determines whether or not a predetermined stop condition is satisfied (S72). Even if the charge / discharge control unit 71 keeps the position of the key 51 at the “charge” position or the “discharge” position and the issued password is not input (NO at S71), the predetermined stop condition Is determined (S72: YES), charging or discharging of the on-vehicle storage battery 102 is stopped (S73). If the predetermined stop condition is not satisfied (NO in S72), the process returns to S70.

  After the charging / discharging control unit 71 stops charging / discharging, the password processing unit 77 determines whether the issued password is input (S74). If authentication of the password is successful at this time, or if authentication is successful in S71 and charging / discharging is stopped (YES in S74), the operation determining unit 74 determines that the position of the key 51 is the "charging" position or It is determined whether the "discharge" position is switched to the "stop" position (S75). If the switch to the "stop" position at this time, or if the charge / discharge is stopped by switching to the "stop" position at S70 (YES at S75), the connector control unit 76 unlocks the connector 3 (S76).

  On the other hand, if the issued password has not been input (NO in S74), or if it has not been switched to the "stop" position (NO in S75), the process returns to S74. Specifically, the password processing unit 77 waits for the issued password until it is input. In addition, the operation determination unit 74 stands by until switching to the “stop” position. That is, the lock operation of the connector 3 is released only when the stop operation is accepted when the password authentication succeeds and the three-position switch 50c receives the stop operation.

  Thus, the charge / discharge device 1a determines whether the lock release of the connector 3 can be performed or not by authenticating the password issued each time the charge / discharge is performed. Therefore, in addition to the effect exhibited by the charge / discharge device 1 of the first embodiment, unlocking of the connector 3 by a third party not intended by the user can be more firmly prevented.

  Note that the three-position switch 50c may not be able to switch on and off the power supply 30. In this case, the processes of S61 and S66 are not performed. In this case, the power supply 30 is on.

Third Embodiment
Other embodiments of the present invention are described below.

  In the first embodiment, the case of using a loaned member (e.g., the key 51, a card or a ticket) has been described, but instead of the loaned member, a piece of paper (member to be issued) issued when charging / discharging is started is used. It does not matter.

  FIG. 8 is a view showing a configuration example of the charge and discharge device 1b. As shown in FIG. 8, in the charge / discharge device 1b, (1) the charge / discharge device main body 2b includes an issuing unit 80 and a reading unit 90 instead of the key switch 50 and the key 51, and (2) a control unit 70b. Is different from the charge and discharge device 1 of the first embodiment in that the operation determination unit 74 b (operation unit) and the issuance processing unit 78 are provided.

  The issuing unit 80 is a sheet issuing mechanism that issues a sheet to which identification information has been assigned each time charging and discharging are performed. Identification information is information for identifying each sheet of paper. The issuing unit 80 prints, for example, a QR code (registered trademark) as identification information on each piece of paper. Each time the touch panel 40 (operation unit) receives a start operation, the issuance processing unit 78 controls the issuing unit 80 to issue the sheet after giving identification information.

  The reading unit 90 can receive the stop operation by the operation determination unit 74 b by reading the identification information attached to the sheet of paper issued by the issuing unit 80.

  The operation determination unit 74 b receives the stop operation by reading the identification information by the reading unit 90. Specifically, the operation determination unit 74 b collates the identification information of the sheet read by the reading unit 90 with the identification information given by the issuing unit 80 when the sheet is issued. The operation determination unit 74b receives the stop operation when it is determined that the identification information matches as a result of the comparison.

  In the charge / discharge device 1b, for example, when the touch panel 40 receives a start operation, the issuing unit 80 issues a sheet in a state where identification information is given. Thereafter, when it is determined that the connector 3 is connected to the charging port 101, the control unit 70b locks the connector 3 and then charges and discharges the in-vehicle storage battery 102.

  When the charging / discharging is stopped or the lock of the connector 3 is released, the user holds the sheet over the reading unit 90 to read the identification information given to the sheet. The operation determination unit 74 b collates identification information. If the verification is successful, the operation determination unit 74b receives the stop operation. As a result, after stopping charging and discharging of the on-board storage battery 102, the control unit 70b releases the lock of the connector 3. In addition, when the controller 70b satisfies the predetermined stop condition and stops the charging and discharging, the controller 70b does not release the lock of the connector 3 until the matching is successful.

  The start operation may be accepted by a start button (not shown) instead of the touch panel 40. In this case, the start button functions as an operation unit. In addition, the touch panel 40 or a stop button (not shown) may receive a stop operation. In this case, the operation unit is realized by the touch panel 40, the start button or the stop button.

  Further, the identification information may be added to the ticket described as a modification of the first embodiment, as in the case of the above-described sheet. That is, in this case, the above-described ticket functions as an issued member. In addition, the issuing unit 80 has the function of the above-described ticket issuing mechanism. The operation determination unit 74b receives the stop operation based on the collation result of the identification information given to the ticket.

[Example of software implementation]
The control block of the charge / discharge device 1 (in particular, each portion included in the control unit 70 of the charge / discharge device body 2 and each portion included in the control unit 70a of the charge / discharge device body 2a) is formed in an integrated circuit (IC chip) or the like. It may be realized by a logic circuit (hardware) or software.

  In the latter case, the charge / discharge device 1 includes a computer that executes instructions of a program that is software that implements each function. The computer includes, for example, one or more processors, and a computer readable recording medium storing the program. Then, in the computer, the processor reads the program from the recording medium and executes the program to achieve the object of the present invention. For example, a CPU (Central Processing Unit) can be used as the processor. As the above-mentioned recording medium, a tape, a disk, a card, a semiconductor memory, a programmable logic circuit or the like can be used besides “a non-temporary tangible medium”, for example, a ROM (Read Only Memory). In addition, a RAM (Random Access Memory) or the like for developing the program may be further provided. The program may be supplied to the computer via any transmission medium (communication network, broadcast wave, etc.) capable of transmitting the program. Note that one aspect of the present invention can also be realized in the form of a data signal embedded in a carrier wave in which the program is embodied by electronic transmission.
