Summary of the Invention

Problems to be Solved by the Invention

[0004] In the vehicle disclosed in Patent Document 1, charging is not performed from when the connector is unlocked until it is relocked. Therefore, when the connector is unlocked in conjunction with a door unlock during external charging, charging may stop unintentionally. Thus, it is desired to suppress the unintentional stop of external charging or external power supply.

[0005] The present disclosure has been made to solve the above problems, and an object thereof is to provide a vehicle and a power device capable of suppressing the unintentional stop of external charging or external power supply.

Means for Solving the Problems

[0006] A vehicle relating to the first aspect of this disclosure includes a secondary battery, a vehicle inlet to which a vehicle plug capable of power transmission including at least one of external charging and external power supply is connected, an electronic lock that locks the vehicle inlet and the vehicle plug, and a vehicle control device that controls the electronic lock. When the vehicle control device receives a request from the user to release the lock by the electronic lock, it prohibits the release of the lock by the electronic lock if the output of the power transmission is greater than a predetermined value, and when the vehicle control device receives a request from the user to release the lock by the electronic lock, it releases the lock by the electronic lock if the output of the power transmission is less than or equal to a predetermined value.

[0007] In the vehicle relating to the first aspect of this disclosure, as described above, when a request to release the electronic lock is received, if the power transmission output is greater than a predetermined value, the release of the electronic lock is prohibited. This prevents the electronic lock from being released based on a request to release the electronic lock when the power transmission output is greater than a predetermined value due to external charging or external power supply. As a result, it is possible to suppress the unintended cessation of external charging or external power supply. Furthermore, in the vehicle relating to the first aspect described above, when a request to release the electronic lock is received, the electronic lock is released if the power transmission output is less than or equal to a predetermined value. This allows the electronic lock to be released based on a request to release the electronic lock when the power transmission output is less than or equal to a predetermined value due to the absence of external charging or external power supply.

[0008] In the vehicle relating to the first phase described above, preferably, the vehicle control device is an electronic lock. When the lock is released, the system prohibits the initiation of power transmission under conditions where the power transmission output exceeds a predetermined value. With this configuration, the output threshold at which power transmission is initiated when the electronic lock is released can be aligned with the output threshold at which the electronic lock is permitted to be released.

[0009] The vehicle relating to the first phase described above preferably further includes a notification device for notifying the user. When the vehicle control device receives a request from the user to release the lock by electronic lock, and the release of the lock by electronic lock is prohibited due to the power transmission output being greater than a predetermined value, the vehicle control device notifies the notification device that the power transmission output is greater than a predetermined value. With this configuration, the user can understand that the power transmission output is greater than a predetermined value through the notification device.

[0010] The vehicle relating to the first phase described above preferably further comprises a communication device that communicates with a terminal capable of receiving user input. The communication device transmits a signal to the terminal regarding the release of the electronic lock when the vehicle control device prohibits the release of the lock by the electronic lock due to the power transmission output being greater than a predetermined value. With this configuration, the user can obtain information regarding the release of the lock by the electronic lock using the terminal.

[0011] In the vehicle relating to the first phase described above, preferably, a request to release the lock by the electronic lock includes a first request and a second request different from the first request. When the vehicle control device receives the first request from the user, if the power transmission output is greater than a predetermined value, it prohibits the release of the lock by the electronic lock. When the vehicle control device receives the first request from the user, if the power transmission output is less than or equal to the predetermined value, it releases the lock by the electronic lock. When the vehicle control device receives the second request from the user, regardless of the power transmission output, it controls the power transmission output to be less than or equal to the predetermined value and releases the lock by the electronic lock. With this configuration, when the first request is received, the release of the lock by the electronic lock can be controlled based on the magnitude of the power transmission output. Furthermore, when the second request is received, the lock by the electronic lock can be forcibly released regardless of the magnitude of the power transmission output.

[0012] In this case, preferably, the vehicle further includes vehicle doors for entering and exiting the vehicle. The first request is a request to release the lock by an electronic lock linked to the unlocking of the vehicle door, and the second request is a request to release the lock by an electronic lock based on the pressing of an unlock button provided on the vehicle plug. With this configuration, when a request to release the lock by an electronic lock linked to the unlocking of the vehicle door is received, the release of the lock by the electronic lock can be controlled based on the magnitude of the power transmission output. Also, when the above release request based on the pressing of the unlock button is received, the lock by the electronic lock can be forcibly released regardless of the magnitude of the power transmission output.

[0013] The power device relating to the second aspect of this disclosure comprises a vehicle plug capable of power transmission including at least one of external charging and external power supply, which is connected to the vehicle inlet of a vehicle equipped with a secondary battery, and a device-side control device that controls an electronic lock that locks the vehicle inlet and the vehicle plug. When the device-side control device receives a request from the user to release the lock by the electronic lock, it prohibits the release of the lock by the electronic lock if the output of the power transmission is greater than a predetermined value, and when it receives a request from the user to release the lock by the electronic lock, it releases the lock by the electronic lock if the output of the power transmission is less than or equal to a predetermined value. Note that controlling the electronic lock has a broad meaning that also includes indirectly controlling the electronic lock by transmitting a command to the vehicle to control the electronic lock.

[0014] In the vehicle relating to the second aspect of this disclosure, as described above, the lock is released by the electronic lock. When a request to unlock the device is received, if the power transmission output is greater than a predetermined value, the unlocking of the electronic lock is prohibited. Conversely, when a request to unlock the electronic lock is received, if the power transmission output is less than or equal to a predetermined value, the lock is released. This makes it possible to provide a power device that can prevent external charging or external power supply from unintentionally stopping when the power transmission output is greater than a predetermined value. Furthermore, it is possible to provide a power device that can release the lock based on a request to release the electronic lock when the power transmission output is less than or equal to a predetermined value. [Effects of the Invention]

[0015] According to this disclosure, it is possible to prevent external charging or external power supply from unintentionally stopping. [Brief explanation of the drawing]

[0016] [Figure 1] This is a diagram showing the configuration of the vehicle according to the first embodiment. [Figure 2] This is a flowchart illustrating the control of a vehicle control device according to the first embodiment. [Figure 3] This figure shows the notification display in the notification device according to the first embodiment. [Figure 4] Figure 2 is a flowchart showing the detailed control of step S110. [Figure 5] This figure shows the screen of a mobile terminal according to the first embodiment. [Figure 6] This figure shows the configuration of the power station and vehicle according to the second embodiment. [Figure 7] This is a flowchart illustrating the control of the stand control device according to the second embodiment. [Modes for carrying out the invention]

[0017] Embodiments of this disclosure will be described in detail below with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and their descriptions will not be repeated.

[0018] <First Embodiment> <Overall Configuration> FIG. 1 is a diagram showing the configuration of a vehicle 100 according to the first embodiment. The vehicle 100 includes a vehicle control device (ECU: Electronic Control Unit) 10, a battery 20, a DC / AC converter 30, a vehicle inlet 40, an electronic lock 50, a current sensor 60, a notification device 70, a communication device 80, and a vehicle door 90. The battery 20 is an example of the "secondary battery" of the present disclosure. Also, for simplicity, only one vehicle door 90 is shown in the figure. The vehicle 100 is, for example, a battery electric vehicle (BEV). The vehicle 100 may be a hybrid electric vehicle (HEV),

[0019] or a plug-in hybrid electric vehicle (PHEV), or a fuel cell electric vehicle (FCEV). The battery 20 is a power storage device that stores power for driving the vehicle 100. The vehicle inlet 40 is configured to be connectable to a vehicle plug 120 that can externally supply power to a home appliance 900 (e.g., a rice cooker or a refrigerator). When the vehicle plug 120 is connected to the vehicle inlet 40 of the vehicle 100, the vehicle 100 is electrically connected to the home appliance 900. Thereby, external power supply for supplying the power of the battery 20 to the home appliance 900 can be executed. Note that the external power supply is an example of the "power transmission" of the present disclosure.

[0020]

[0021] ​​Furthermore, the electronic lock 50 locks the vehicle inlet 40 and the vehicle plug 120. Specifically, the position of the electronic lock 50 is changed so as to press against a mechanical lock (not shown) provided on the vehicle plug 120, thereby locking the vehicle inlet 40 and the vehicle plug 120. The mechanical lock is used to engage the vehicle plug 120 with the vehicle inlet 40. It has a function to connect. The position of the electronic lock 50 is controlled by the vehicle control device 10. That is, the vehicle control device 10 controls the connection state between the vehicle inlet 40 and the vehicle plug 120. In the following, when the lock between the vehicle inlet 40 and the vehicle plug 120 by the electronic lock 50 is released, it will be referred to as the electronic lock 50 being released.

[0022] The vehicle control device 10 controls the external power supply from the vehicle 100 to the home appliance 900. The vehicle control device 10 includes a processor 11, RAM (Random Access Memory) 12, and a storage device 13. The processor 11 includes, for example, a CPU (Central Processing Unit). The RAM 12 includes working memory for temporarily storing data processed by the processor 11. The storage device 13 is configured to store stored information. The storage device 13 stores programs as well as information used by the programs (for example, maps, formulas, and various parameters). In the first embodiment, various controls in the vehicle control device 10 are performed by the processor 11 executing the programs stored in the storage device 13.

[0023] The DC / AC converter 30 converts the DC power from the battery 20 into AC power. As a result, the AC power from the DC / AC converter is supplied to the home appliance 900 via the vehicle plug 120.

[0024] The current sensor 60 detects the output of the external power supply. Specifically, the current sensor 60 detects the current value flowing between the vehicle inlet 40 and the DC / AC converter 30. The current value detected by the current sensor 60 is transmitted to the vehicle control device 10.

[0025] The notification device 70 provides notifications to the user of the vehicle 100. For example, in the first embodiment, the notification device 70 is a car navigation system (display device). The notification device 70 may also be an audio output unit that outputs only audio.

[0026] The communication device 80 communicates with the user's mobile terminal 200 (for example, a smartphone) in the vehicle 100. The communication device 80 may also communicate with the user's PC, tablet, etc. Furthermore, the mobile terminal 200 is just one example of a "terminal" as defined in this disclosure.

[0027] In conventional vehicles where the electronic lock automatically locks after a predetermined time has elapsed since the electronic lock was released, external power is not supplied during that predetermined time. Therefore, if the electronic lock is released in conjunction with, for example, the unlocking of the vehicle door while external power is being supplied, the external power supply may be unintentionally stopped. Consequently, it is desirable to prevent the external power supply from being unintentionally stopped.

[0028] Therefore, in the first embodiment, when the vehicle control device 10 receives a request from the user to release the electronic lock 50, it prohibits the release of the electronic lock 50 if the output of the external power supply is greater than 16A, and releases the electronic lock 50 when the user requests the release of the electronic lock 50 and the output of the external power supply is 16A or less. This makes it possible to prevent the external power supply from being stopped by releasing the electronic lock 50 when the output of the external power supply is higher than 16A due to the external power supply being in operation. Specifically, this will be explained with reference to the flow shown in Figure 2.

[0029] <How to control electronic locks> Next, with reference to the flowchart in Figure 2, the control method of the electronic lock 50 by the vehicle control device 10 will be explained.

[0030] In step S100, the vehicle control device 10 controls the vehicle plug 120 to the vehicle inlet The system detects that the vehicle plug 120 has been inserted into the vehicle inlet 40. Specifically, the vehicle control device 10 detects that the vehicle plug 120 has been inserted into the vehicle inlet 40 based on changes in resistance values ​​(within the vehicle 100) caused by the insertion of the vehicle plug 120 into the vehicle inlet 40.

[0031] In step S101, the vehicle control device 10 receives an operation from the user of the vehicle 100 to start external power supply. For example, the vehicle control device 10 detects that an operation to start external power supply has been performed by receiving a predetermined signal based on the user's operation to start external power supply. An operation to start external power supply is, for example, pressing the button 121 (see Figure 1) on the vehicle plug 120 once. The button 121 is an example of the "unlock button" in this disclosure.

[0032] In step S102, the vehicle control device 10 determines whether the output of the external power supply is 16A or less. Specifically, the vehicle control device 10 determines whether the value detected by the current sensor 60 is 16A or less. If the output is 16A or less (Yes in S102), the process proceeds to step S103. If the output is greater than 16A (No in S102), the process ends. Note that at the time of step S102, the vehicle has not yet been locked by the electronic lock 50.

[0033] In step S103, the vehicle control device 10 activates the lock by the electronic lock 50 (sets it to a locked state). Specifically, the vehicle control device 10 changes (moves) the position of the electronic lock 50 so that the mechanical lock is pressed by the electronic lock 50 (the movement of the mechanical lock is restricted by the electronic lock 50).

[0034] In step S104, the vehicle control device 10 starts controlling the external power supply to provide power from the battery 20 to the home appliance 900. Specifically, the vehicle control device 10 starts the external power supply by controlling the on / off state of a switching element (not shown) of the DC / AC converter 30.

[0035] In step S105, the vehicle control device 10 receives a request from the user to release the electronic lock 50.

[0036] In step S106, the vehicle control device 10 determines whether the electronic lock release operation received in step S105 is an operation in which the button 121 (see Figure 1) provided on the vehicle plug 120 is pressed multiple times (for example, three times) in succession. If the button 121 is pressed multiple times in succession (Yes in S106), the process proceeds to step S120. If the button 121 is not pressed multiple times in succession (No in S106), the process proceeds to step S107. Note that the release operation when the button 121 is not pressed multiple times in succession is the release operation of the electronic lock 50 linked to the unlocking of the vehicle door 90 (see Figure 1).

[0037] In step S107, the vehicle control device 10 determines whether the output of the external power supply is greater than 16A. Specifically, the vehicle control device 10 determines whether the detected value of the current sensor 60 is greater than 16A. If the output is greater than 16A (Yes in S107), the process proceeds to step S108. If the output is 16A or less (No in S107), the process proceeds to step S120.

[0038] In step S108, the vehicle control device 10 rejects the request to release the electronic lock 50. In other words, the vehicle control device 10 prohibits the release of the electronic lock 50. As a result, the vehicle remains locked by the electronic lock 50.

[0039] In step S109, the vehicle control device 10 sends a command signal to the notification device 70 (car navigation system) to notify the notification device 70 that the output of the external power supply (detection value of the current sensor 60) is greater than 16A. As a result, as shown in Figure 3, a message indicating that the request to release the electronic lock 50 has been rejected is displayed on the screen 71 of the notification device 70. In addition, a message indicating that the output of the external power supply exceeds 16A is displayed on the screen 71. As a result, the user can understand that the external power supply is continuing. This makes it possible to prevent the user from starting the vehicle 100 while the external power supply is active.

[0040] Referring again to Figure 2, in step S110, the vehicle control device 10 transmits a signal regarding the release of the electronic lock 50 to the mobile terminal 200. Specifically, the vehicle control device 10 controls the transmission of a signal to the mobile terminal 200 via the communication device 80 to indicate that the request to release the electronic lock 50 has been rejected. As a result, a message indicating that the request to release the electronic lock 50 has been rejected is displayed on the screen 202 of the mobile terminal 200 (see Figure 5). The detailed processing of step S110 will be described later.

[0041] In step S120, the vehicle control device 10 performs control to notify via the notification device 70 that the vehicle plug 120 is inserted into the vehicle inlet 40. This makes it possible to prevent the user from starting the vehicle 100 while the vehicle plug 120 is still connected, especially when the electronic lock 50 is released in conjunction with the unlocking of the vehicle door 90 (No in S106).

[0042] In step S121, the vehicle control device 10 controls the output of the external power supply to be 16A or less. For example, the vehicle control device 10 controls the output of the external power supply to be 16A or less by changing the on / off period (duty cycle) of a switching element (not shown) of the DC / AC converter 30. If the output of the external power supply is already 16A or less, the process in step S121 is not performed.

[0043] In step S122, the vehicle control device 10 performs a process to release the electronic lock 50. Specifically, the vehicle control device 10 changes (moves) the position of the electronic lock 50 so that the pressure applied by the electronic lock 50 to the mechanical lock is released.

[0044] In step S123, the vehicle control device 10 performs a process to stop the external power supply. For example, the vehicle control device 10 stops the external power supply by stopping the on / off switching of a switching element (not shown) of the DC / AC converter 30 (setting it to a permanently off state). After that, the process ends.

[0045] <Processing in step S110> As shown in Figure 4, in step S111, the control unit 201 (see Figure 1) of the mobile terminal 200 displays a selection button 202a (see Figure 5) on the screen 202 (see Figure 1) of the mobile terminal 200 for processing to reduce the output of the external power supply. The control unit 201 also displays a selection button 202b (see Figure 5) on the screen 202 for processing to stop the external power supply. The control unit 201 also displays a selection button 202c (see Figure 5) on the screen 202 for processing to maintain the current state.

[0046] In step S112, the control unit 201 of the mobile terminal 200 determines whether the process of reducing the output of the external power supply (or stopping the external power supply) has been selected due to the selection of selection button 201a (or selection button 201b). If the process of reducing the output of the external power supply (or stopping the external power supply) has been selected (Yes in S112), the process proceeds to step S113. If selection button 201c is selected, the process of maintaining the current state is selected. If this is selected (No in S112), the process ends.

[0047] In step S113, if the selection button 202a was selected in step S112, the vehicle control device 10 performs a process to reduce the output of the external power supply. Specifically, the vehicle control device 10 controls the on / off period (duty cycle) of a switching element (not shown) of the DC / AC converter 30, for example, so that the output of the external power supply is 16A or less.

[0048] Furthermore, if the selection button 202b is selected in step S112, the vehicle control device 10 executes a process to stop the external power supply. Specifically, the vehicle control device 10 stops the on / off switching of, for example, a switching element (not shown) of the DC / AC converter 30 (setting it to a permanently off state) so that the external power supply is stopped.

[0049] In step S114, the vehicle control device 10 releases the electronic lock 50. Specifically, the vehicle control device 10 changes the position of the electronic lock 50 so that the pressure applied to the mechanical lock by the electronic lock 50 is released.

[0050] As described above, in the first embodiment, when the vehicle control device 10 receives a request from the user to release the electronic lock 50, it prohibits the release of the electronic lock 50 if the output of the external power supply is greater than 16A. This prevents the electronic lock 50 from being released while external power is being supplied to the home appliance 900, based on the magnitude of the output of the external power supply. As a result, it is possible to prevent the external power supply from stopping unintentionally, thereby improving the efficiency of the external power supply.

[0051] <Second Embodiment> In the second embodiment, unlike the first embodiment in which power is supplied to the home appliance 900, power is supplied to the power stand 400. Components identical to those in the first embodiment are denoted by the same reference numerals and will not be described repeatedly.

[0052] <Overall Structure> Figure 6 shows the configuration of the vehicle 300 and power stand 400 according to the second embodiment. Note that the power stand 400 is an example of the "power device" of this disclosure.

[0053] The vehicle 300 includes a vehicle control device 110, a battery 20, a DC / AC converter 30, a vehicle inlet 40, an electronic lock 50, a current sensor 60, an alarm device 70, a communication device 180, and a vehicle door 90. The vehicle control device 110 includes a processor 111, RAM 112, and a storage device 113.

[0054] The communication device 180 communicates with the user's mobile terminal 200 in the vehicle 300, and with the communication unit 413 of the power station 400, which will be described later.

[0055] The vehicle control device 110 performs control to transmit the current value detected by the current sensor 60 to the communication unit 413 of the power stand 400 via the communication device 180.

[0056] The power stand 400 comprises a stand control device 410 and an operating terminal 420. The stand control device 410 includes a processor 411, a memory 412, and a communication unit 413. The processor 411 controls the communication unit 413. The memory 412 stores programs executed by the processor 411, as well as information used by the programs (e.g., maps, formulas, and various parameters). Note that the stand control device 410 is an example of a "device-side control device" as disclosed herein.

[0057] The power stand 400 is equipped with a vehicle plug 430 that allows for external power supply (power supply from the vehicle 300 to the power stand 400) by being connected to the vehicle inlet 40.

[0058] <How to control electronic locks> Next, the method for controlling the electronic lock 50 by the stand control device 410 will be described with reference to the flowchart in Figure 7. Processes similar to those in the first embodiment described above will be simplified or omitted.

[0059] In step S200, the stand control device 410 detects that the vehicle plug 430 has been inserted into the vehicle inlet 40. For example, the stand control device 410 detects that the vehicle plug 430 has been inserted into the vehicle inlet 40 based on a signal transmitted from the vehicle 300. Alternatively, the stand control device 410 may detect that the vehicle plug 430 has been inserted into the vehicle inlet 40 based on a change in resistance within the stand control device 410.

[0060] In step S201, the stand control device 410 accepts an operation to start external power supply by the user. For example, the stand control device 410 detects that an operation to start external power supply has been performed based on the selection of the power supply start button 421 provided on the operation terminal 420 (see Figure 6). In step S201, information on various parameters related to external power supply (such as power supply voltage and power supply current) is exchanged between the vehicle 300 and the power stand 400.

[0061] In step S202, the stand control device 410 determines whether the output of the external power supply is 16A or less. Specifically, the stand control device 410 determines whether the value detected by the current sensor 60 is 16A or less. If the output of the external power supply is 16A or less (Yes in S202), the process proceeds to step S203. If the output of the external power supply is greater than 16A (No in S202), the process ends. Note that at the time of step S202, the electronic lock 50 has not yet locked the stand.

[0062] In step S203, the power station 400 transmits a lock command signal from the electronic lock 50 to the vehicle 300 via the communication unit 413. In step S301, the vehicle control device 110 activates the electronic lock 50 (sets it to the locked state) based on the command signal from step S203. In step S302, the vehicle control device 110 notifies the power station 400 via the communication device 180 that the electronic lock 50 has been activated (locked).

[0063] In step S204, the stand control device 410 starts controlling the external power supply that provides power from the vehicle 300 to the power stand 400.

[0064] In step S205, the stand control device 410 receives a request from the user to release the electronic lock 50.

[0065] In step S206, the stand control device 410 determines whether the electronic lock release operation received in step S205 is the operation of pressing the emergency stop button 422 provided on the operation terminal 420 (see Figure 6) of the power stand 400. If the emergency stop button 422 is pressed (Yes in S206), the process proceeds to step S220. If the emergency stop button 422 is not pressed (No in S206), the process proceeds to step S207. Note that the release operation when the emergency stop button 422 is not pressed is the release operation of the electronic lock 50 linked to the unlocking of the vehicle door 90 (see Figure 6).

[0066] In step S207, the stand control device 410 determines whether the output of the external power supply is greater than 16A. Specifically, the stand control device 410 determines whether the detected value of the current sensor 60 is greater than 16A. If the output is greater than 16A (Yes in S207), the process proceeds to step S208. If the output is 16A or less (No in S207), the process proceeds to step S220.

[0067] In step S208, the stand control device 410 rejects the request to release the electronic lock 50. In other words, the stand control device 410 prohibits the release of the electronic lock 50. In this case, since no command to release the electronic lock 50 is sent from the power stand 400 to the vehicle 300, the lock state by the electronic lock 50 continues.

[0068] In step S209, the stand control device 410 transmits a command signal to the vehicle 300 to cause the notification device 70 (car navigation system) to notify that the output of the external power supply (detection value of the current sensor 60) is greater than 16A. Based on the above command signal, the vehicle control device 110 controls the notification device 70 so that a message indicating that the request to release the electronic lock 50 has been rejected is displayed on the screen 71 of the notification device 70 (see Figure 3).

[0069] In step S210, the stand control device 410 displays the content displayed on the screen 202 of the mobile terminal 200 (see Figure 5) in the first embodiment on the operation terminal 420 of the stand control device 410. Alternatively, the stand control device 410 may display the content on the screen 202 of the mobile terminal 200, as in the first embodiment.

[0070] In step S220, the stand control device 410 notifies the vehicle 110 via the communication unit 413 that the vehicle plug 120 is inserted into the vehicle inlet 40.

[0071] In step S221, the stand control device 410 controls the output of the external power supply to be 16A or less. For example, the stand control device 410 sends a command signal to the vehicle 300 to change the on / off period (duty cycle) of a switching element (not shown) of the DC / AC converter 30. If the output of the external power supply is already 16A or less, the process in step S221 is not performed.

[0072] In step S222, the stand control device 410 transmits a command signal to the vehicle 300 to release the electronic lock 50.

[0073] In step S223, the stand control device 410 detects that the electronic lock 50 has been released in the vehicle 300 based on the command signal in step S222, and then stops the external power supply. After that, the process ends.

[0074] In the first and second embodiments described above, examples were shown where both the threshold value of the output of the external power supply that enables the start of external power supply and the threshold value of the output of the external power supply that prohibits the release of the electronic lock 50 are 16A, but the disclosure is not limited thereto. The threshold value of the output of the external power supply that enables the start of external power supply and the threshold value of the output of the external power supply that prohibits the release of the electronic lock 50 may be different values ​​from each other.

[0075] In the first and second embodiments described above, control during external power supply was shown as an example, but this disclosure is not limited thereto. Control similar to that in the first and second embodiments may also be performed during external charging (charging the vehicle from a home appliance or power station).

[0076] In the first embodiment described above, if the release of the electronic lock 50 is prohibited, the mobile terminal 200 While examples have been shown in which each of the mobile terminal 200 and the notification device 70 is controlled, this disclosure is not limited thereto. For example, only one of the mobile terminal 200 and the notification device 70 may be controlled. Alternatively, neither the mobile terminal 200 nor the notification device 70 may be controlled. Furthermore, in the second embodiment as well, if the release of the electronic lock 50 is prohibited, only one of the operating terminal 420 and the notification device 70 of the power stand 400 may be controlled. Alternatively, neither the operating terminal 420 nor the notification device 70 may be controlled.

[0077] In the first (second) embodiment described above, an example was shown in which the electronic lock 50 is released regardless of the output of the external power supply when the button 121 of the vehicle plug 120 (the emergency stop button 422 of the power stand 400) is pressed, but the disclosure is not limited thereto. Even in the above case, the release of the electronic lock 50 may be prohibited under conditions where the output of the external power supply is greater than 16A.

[0078] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of this disclosure is indicated by the claims rather than by the description of the embodiments above, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
