Abstract

To enhance convenience of a user in external charging using a charging facility provided with a connector locking device.SOLUTION: With a DC lid opened, a door lock operation is performed at time t11. Thus, a door lock command is sent from a verification ECU to a body ECU. While shifting the door lock device to a locked state according to a door lock command, the body ECU leaves a lid lock device of the DC lid unlocked. When a start operation for starting DC charging is performed by a user at time t12, the body ECU shifts the lid lock device of the DC lid to a locked state. When the DC charging is completed at time t13, the body ECU brings the lid lock device of the DC lid into an unlocked state. At time t14, the DC lid is closed.SELECTED DRAWING: Figure 6

Description

[Technical Field]

[0001] The present disclosure relates to a vehicle, and more particularly to a vehicle configured to be capable of performing external charging, in which an on-board power storage device is charged by a charging facility provided outside the vehicle. [Background technology]

[0002] Japanese Patent Application Laid-Open Publication No. 2020-114040 (Patent Document 1) discloses a vehicle that is configured to be externally charged. This vehicle can operate a lid lock device and a connector lock device in conjunction with a door lock device, and a common relay is used to switch between supplying and cutting off operating power to each lock device (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-114040 Summary of the Invention [Problem to be solved by the invention]

[0004] Charging equipment may be provided with a connector locking device that locks the connection between the charging connector of the charging equipment and the vehicle inlet. Charging equipment equipped with a connector locking device releases the connection between the charging connector and the inlet when external charging is completed, allowing the user to remove the charging connector from the inlet.

[0005] When leaving the vehicle during external charging, the user typically locks the vehicle doors. When returning to the vehicle, if external charging has been completed, the user removes the charging connector from the inlet and closes the lid.

[0006] However, as in the vehicle disclosed in Patent Document 1, when the lid lock device is locked in conjunction with the door lock device, even if the user tries to close the lid, the lid cannot be closed because the lid lock device is locked. In order to unlock the lid lock device, the door must be unlocked, which leaves room for improvement in terms of user convenience.

[0007] The present disclosure has been made to solve the above-mentioned problems, and an object of the present disclosure is to improve user convenience in external charging using charging equipment equipped with a connector locking device. [Means for solving the problem]

[0008] A vehicle according to an aspect of the present disclosure is configured to perform first external charging, which charges an on-board power storage device using power supplied by first charging equipment provided external to the vehicle. The vehicle includes: a first power receiving port configured to be connectable to a first connector of the first charging equipment; a first lid provided at the first power receiving port; a first lid lock device configured to switch the first lid between a locked state and an unlocked state; and a control device that controls the first lid lock device to the locked state or the unlocked state. When a vehicle access door is locked, the control device locks the first lid lock device in conjunction with locking of the access door when the first lid is closed; when the first lid is open, the control device keeps the first lid lock device unlocked until first external charging starts; when first external charging starts, the control device locks the first lid lock device; and when first external charging is completed, the control device unlocks the first lid lock device.

[0009] According to the above configuration, even if the vehicle's access door is locked, if the first lid is open, the control device does not link the first lid lock device to locking of the access door. The control device keeps the first lid lock device unlocked until first external charging starts, allowing the user to close the first lid even at this stage. The control device then locks the first lid lock device when first external charging starts, and unlocks the first lid lock device when first external charging is completed. Because the first lid lock device is unlocked upon completion of first external charging, a user who removes the first connector from the first power receiving port can close the first lid without any operation. This improves user convenience.

[0010] In one embodiment, the first charging facility includes a first connector locking device configured to switch the connection between the first connector and the first power receiving port between a locked state and an unlocked state. When the first external charging is performed, the first connector locking device locks the connection between the first connector and the first power receiving port, and when the first external charging is completed, the first connector locking device unlocks the connection between the first connector and the first power receiving port.

[0011] According to the above configuration, the first connector locking device that switches the connection between the first connector and the first power receiving port between a locked state and an unlocked state is provided to the first charging equipment. The first power receiving port is then set to an unlocked state when the first external charging is completed. This allows the user to remove the first connector from the first power receiving port without any operation after the first external charging is completed.

[0012] In one embodiment, the vehicle further includes a relay that switches between supplying and cutting off operating power to the first lid lock device. The control device controls the relay to place the first lid lock device in a locked state or an unlocked state.

[0013] According to the above configuration, the control device can control the first lid lock device by controlling the relay.

[0014] In one embodiment, the vehicle is further configured to perform second external charging, which charges the power storage device using power supplied by second charging equipment provided external to the vehicle. The vehicle further includes a second power receiving port configured to be connectable to a second connector of the second charging equipment, a second lid provided at the second power receiving port, a second lid locking device configured to switch the second lid between a locked state and an unlocked state, and a second connector locking device configured to switch the connection between the second connector and the second power receiving port between the locked state and the unlocked state. The second lid locking device and the second connector locking device are configured to receive operating power via a relay.

[0015] According to the above configuration, the second lid locking device and the second connector locking device receive activation power through a relay, just like the first lid locking device. Because there is no need to provide a separate relay for each locking device, the circuits for activating each locking device can be configured inexpensively. Furthermore, because the relay for activating each locking device is shared, for example, when first external charging begins, the second lid locking device is also locked. This makes it possible to prevent tampering with the second lid and second power receiving port while first external charging is being performed.

[0016] In one embodiment, the first external charging is DC charging and the second external charging is AC charging. [Effects of the Invention]

[0017] According to the present disclosure, it is possible to improve user convenience in external charging using charging equipment equipped with a connector locking device. [Brief explanation of the drawings]

[0019] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals, and description thereof will not be repeated.

[0020] <Vehicle configuration> FIG. 1 is a diagram schematically illustrating an example of the overall configuration of a vehicle 1 according to an embodiment of the present disclosure. Referring to FIG. 1, vehicle 1 includes a power storage device 10, a system main relay (SMR) 15, a power control unit (PCU) 20, a drive unit 25, and drive wheels 30. Vehicle 1 is an electric vehicle that drives drive wheels 30 via drive unit 25 using power stored in power storage device 10. Vehicle 1 is configured to enable alternating current (AC) charging, in which power storage device 10 is charged using AC power supplied from an alternating current (AC) charging facility 200 external to vehicle 1, and direct current (DC) charging, in which power storage device 10 is charged using DC power supplied from a direct current (DC) charging facility 300 external to vehicle 1. Note that vehicle 1 may be, for example, a plug-in hybrid vehicle further equipped with an engine, or a fuel cell vehicle further equipped with a fuel cell as a power source in addition to power storage device 10.

[0021] The power storage device 10 is a rechargeable power storage element. The power storage device 10 includes, for example, a secondary battery such as a lithium-ion battery or a nickel-metal hydride battery, or a power storage element such as an electric double layer capacitor. Note that the lithium-ion secondary battery is a secondary battery that uses lithium as a charge carrier, and may include not only a typical lithium-ion secondary battery that uses a liquid electrolyte, but also a so-called all-solid-state battery that uses a solid electrolyte.

[0022] SMR 15 is a relay provided between power storage device 10 and power line L1, and serves to electrically connect / disconnect power storage device 10 and power line L1.

[0023] PCU 20 collectively represents a power conversion device that receives electric power from power storage device 10 and drives drive device 25. PCU 20 includes, for example, an inverter that drives a motor included in drive device 25, and a converter that boosts the electric power output from power storage device 10.

[0024] The drive device 25 collectively refers to devices for driving the drive wheels 30. The drive device 25 includes, for example, a motor and an engine that drive the drive wheels 30. The drive device 25 also generates electricity using the motor that drives the drive wheels 30 when braking the vehicle, and outputs the generated electricity to the PCU 20.

[0025] Vehicle 1 further includes a power receiving port unit 40, an AC lid 42, a charger 50, and a charging relay 55 as components for performing AC charging. Similar to a conventional fuel filler port, power receiving port unit 40 is configured by forming a recess on the outer surface of the vehicle. Power receiving port unit 40 is provided with an AC inlet 41 ( FIG. 2 ) to which a connector 220 of a charging cable 210 connected to AC charging equipment 200 can be attached. AC lid 42 is a cover for power receiving port unit 40, and is attached to power receiving port unit 40 by a joint such as a hinge so as to be able to open and close.

[0026] A connector connection signal P1 indicating the connection state between the AC inlet 41 and the connector 220 of the charging cable 210 is output from the power receiving port unit 40 to a charging ECU (Electronic Control Unit) 60 (described later). The connector connection signal P1 is activated, for example, when the connector 220 is connected to the AC inlet 41.

[0027] The power receiving port unit 40 is provided with a lid switch 81 that detects the open / closed state of the AC lid 42. The lid switch 81 outputs a lid signal K1 indicating the open / closed state of the AC lid 42 to the charging ECU 60. The lid signal K1 is activated, for example, when the AC lid 42 is closed.

[0028] The power receiving port unit 40 is further provided with a lid locking device 82 and a connector locking device 83. The lid locking device 82 is configured to switch the closed AC lid 42 between a locked state and an unlocked state. The connector locking device 83 is configured to switch the connection between the connector 220 of the charging cable 210 and the AC inlet 41 between a locked state and an unlocked state. The configurations of the power receiving port unit 40, the lid locking device 82, and the connector locking device 83 will be described in detail later.

[0029] When connector 220 of AC charging equipment 200 is connected to AC inlet 41 of power receiving port unit 40, charger 50 converts AC power supplied from AC charging equipment 200 into a voltage level of power storage device 10 and outputs the converted power. Charger 50 is configured to include, for example, a PFC (Power Factor Correction) circuit, an inverter, an insulating transformer, a rectifier circuit, etc. Charging relay 55 is a relay for electrically connecting / disconnecting charger 50 to / from power line L2 connected to power line L1.

[0030] Vehicle 1 further includes a power receiving port unit 45, a DC lid 47, and a charging relay 57 as components for performing DC charging. Similar to conventional fuel filler ports, power receiving port unit 45 is configured by forming a recess on the outer surface of the vehicle. Power receiving port unit 45 has a configuration that complies with the CHAdeMO (registered trademark) or GB / T charging standards. Power receiving port unit 45 is provided with a DC inlet 46 ( FIG. 3 ) to which a connector 320 of a charging cable 310 connected to DC charging equipment 300 can be attached. DC lid 47 is a lid for power receiving port unit 45, and is attached to power receiving port unit 45 by a joint such as a hinge so as to be able to open and close.

[0031] A connector connection signal P2 indicating the connection state between the DC inlet 46 and the connector 320 of the charging cable 310 is output from the power receiving port unit 45 to the charging ECU 60 (described later). The connector connection signal P2 is activated, for example, when the connector 220 is connected to the DC inlet 46.

[0032] The power receiving port unit 45 is provided with a lid switch 86 that detects the open / closed state of the DC lid 47. The lid switch 86 outputs a lid signal K2 indicating the open / closed state of the DC lid 47 to the charging ECU 60. The lid signal K2 is activated, for example, when the DC lid 47 is closed.

[0033] The power receiving port unit 45 is further provided with a lid lock device 87. The lid lock device 87 is configured to switch the closed DC lid 47 between a locked state and an unlocked state. The configurations of the power receiving port unit 45 and the lid lock device 87 will be described in detail later.

[0034] DC charging equipment 300 according to this embodiment complies with the CHAdeMO or GB / T charging standard. Therefore, a connector locking device that switches the connection between connector 320 and DC inlet 46 between a locked state and an unlocked state is provided in DC charging equipment 300. Therefore, power receiving port unit 45 according to this embodiment does not include a connector locking device.

[0035] The vehicle 1 further includes a charging ECU 60, a body ECU 65, a verification ECU 70, a door lock device 80, lock relays 100 and 101, and unlock relays 102 and 103. The lock relay 100 and the unlock relay 102 are housed in, for example, a relay box 150. The lock relay 101 and the unlock relay 103 are housed in, for example, a relay box 160.

[0036] Each of the charging ECU 60, body ECU 65, and verification ECU 70 includes a CPU (Central Processing Unit), memory (RAM (Random Access Memory) and ROM (Read Only Memory)), and an I / F device for inputting and outputting various signals (none of which are shown). The CPU loads a program stored in the ROM into the RAM and executes it. The program stored in the ROM describes the processes to be executed by the CPU. The charging ECU 60, body ECU 65, and verification ECU 70 are connected via an in-vehicle network such as a CAN (Controller Area Network), and can exchange information with each other.

[0037] In this embodiment, an example is described in which the control unit is divided into a charging ECU 60, a body ECU 65, and a verification ECU 70, but any two or all of the charging ECU 60, the body ECU 65, and the verification ECU 70 may be configured as a single ECU.

[0038] The charging ECU 60 receives a connector connection signal P1 indicating the connection state between the connector 220 of the AC charging equipment 200 and the AC inlet 41 from the power receiving port unit 40. The charging ECU 60 also receives a lid signal K1 indicating the open / close state of the AC lid 42 from the lid switch 81. The charging ECU 60 also receives a connector connection signal P2 indicating the connection state between the connector 320 of the DC charging equipment 300 and the DC inlet 46 from the power receiving port unit 45. The charging ECU 60 also receives a lid signal K2 indicating the open / close state of the DC lid 47 from the lid switch 86.

[0039] Furthermore, when connector 220 of AC charging equipment 200 is connected to AC inlet 41 and predetermined preparation processing for performing AC charging is completed, charging ECU 60 turns on charging relay 55. Then, charging ECU 60 performs predetermined calculation processing based on signals from various sensors and information stored in memory, and performs AC charging by controlling charger 50 based on the calculation results. Furthermore, when connector 320 of DC charging equipment 300 is connected to DC inlet 46 and predetermined preparation processing for performing DC charging is completed, charging ECU 60 turns on charging relay 57. This allows DC charging to be performed.

[0040] The verification ECU 70 wirelessly communicates with a portable device 90 carried by a user, thereby executing control for permitting the door lock device 80 to lock and unlock an entry / exit door (not shown). Specifically, when the verification ECU 70 detects a door lock operation by the user while the vehicle 1 is stopped, the verification ECU 70 performs ID verification of the portable device 90. Note that the door lock operation is, for example, an action in which the user operates a door lock switch provided on the portable device 90 or touches a door lock sensor provided on a door handle.

[0041] When ID verification of the portable device 90 is successful, the verification ECU 70 outputs a door lock command to the body ECU 65. The verification ECU 70 also verifies the ID of the portable device 90 when detecting a door unlock operation by the user, and outputs a door unlock command to the body ECU 65 when ID verification is successful.

[0042] The body ECU 65 controls the door locking device 80 based on a door lock command or a door unlock command received from the verification ECU 70. The door locking device 80 is configured to switch the closed entry / exit doors between a locked state and an unlocked state. The door locking device 80 is provided with a lock relay 100 and an unlock relay 102. The lock relay 100 is a relay that switches between supplying and cutting off operating power to operate the door locking device 80 so as to lock the entry / exit doors. The unlock relay 102 is a relay that switches between supplying and cutting off operating power to operate the door locking device 80 so as to unlock the entry / exit doors.

[0043] When the body ECU 65 receives a door lock command from the verification ECU 70, it turns on the lock relay 100. This activates the door lock device 80, and the entry / exit door is locked. When the body ECU 65 receives a door unlock command from the verification ECU 70, it turns on the unlock relay 102. This activates the door lock device 80, and the entry / exit door is unlocked.

[0044] As will be explained in detail later, the lid lock device 82, the connector lock device 83, and the lid lock device 87 are provided with a common lock relay 101 and an unlock relay 103. In other words, the lid lock device 82, the connector lock device 83, and the lid lock device 87 are configured to operate in conjunction with each other.

[0045] The lock relay 101 is a relay that switches between supplying and cutting off operating power for operating the lid lock device 82 to lock the AC lid 42, operating power for operating the connector lock device 83 to lock the connection between the AC inlet 41 and the connector 220, and operating power for operating the lid lock device 87 to lock the DC lid 47. The unlock relay 103 is a relay that switches between supplying and cutting off operating power for operating the lid lock device 82 to unlock the AC lid 42, operating power for operating the connector lock device 83 to unlock the connection between the AC inlet 41 and the connector 220, and operating power for operating the lid lock device 87 to unlock the lid 47.

[0046] Fig. 2 is a diagram showing an example of the configuration of the power receiving port unit 40 shown in Fig. 1. Referring to Fig. 2, the power receiving port unit 40 is provided with an AC inlet 41, a lid switch 81, a lid lock device 82, and a connector lock device 83.

[0047] AC inlet 41 is configured to be connectable to connector 220 of charging cable 210. When connector 220 is connected to AC inlet 41, a connector connection signal P1 output to charging ECU 60 is activated.

[0048] The lid switch 81 is configured to be able to detect the opening and closing of the AC lid 42. When the lid switch 81 is pressed as a result of the AC lid 42 being closed, a lid signal K1 output to the charging ECU 60 is activated.

[0049] The lid lock device 82 is configured to include, for example, a lock pin 82a that can advance and retreat, and a drive device 82b that drives the lock pin 82a. The lid lock device 82 enters a locked state in which the AC lid 42 cannot be opened by advancing the lock pin 82a from the unlocked state position. The lid lock device 82 enters an unlocked state in which the AC lid 42 can be opened by retracting the lock pin 82a from the locked state position. The lid lock device 82 can be operated regardless of whether the AC lid 42 is open or closed, and can also be operated when the AC lid 42 is open.

[0050] Connector locking device 83 is provided near the outer periphery of AC inlet 41 and is configured to include, for example, a lock pin 83a that can advance and retreat, and a drive device 83b that drives lock pin 83a. Connector locking device 83 enters a locked state in which connector 220 of charging cable 210 connected to AC inlet 41 cannot be removed from AC inlet 41 by advancing lock pin 83a from an unlocked state position. Connector locking device 83 enters an unlocked state in which connector 220 can be removed from AC inlet 41 by retracting lock pin 83a from the locked state position. Connector locking device 83 can be operated regardless of whether connector 220 is connected to AC inlet 41 or not, and can also be operated when connector 220 is not connected to AC inlet 41.

[0051] Fig. 3 is a diagram showing an example of the configuration of the power receiving port unit 45 shown in Fig. 1. Referring to Fig. 3, the power receiving port unit 45 is provided with a DC inlet 46, a lid switch 86, and a lid lock device 87.

[0052] DC inlet 46 is configured to be connectable to connector 320 of charging cable 310. When connector 320 is connected to DC inlet 46, a connector connection signal P2 output to charging ECU 60 is activated.

[0053] The lid switch 86 is configured to be able to detect the opening and closing of the DC lid 47. When the lid switch 86 is pressed down as a result of the DC lid 47 being closed, a lid signal K2 output to the charging ECU 60 is activated.

[0054] The lid lock device 87 includes, for example, a lock pin 87a that can advance and retreat, and a drive device 87b that drives the lock pin 87a. The lid lock device 87 enters a locked state in which the DC lid 47 cannot be opened by advancing the lock pin 87a from the unlocked state position. The lid lock device 87 enters an unlocked state in which the DC lid 47 can be opened by retracting the lock pin 87a from the locked state position. The lid lock device 87 can be operated regardless of whether the DC lid 47 is open or closed, and can also be operated when the DC lid 47 is open.

[0055] 4 is a diagram showing an example of the configuration of a circuit for activating the lid lock device 82, the connector lock device 83, and the lid lock device 87. In the vehicle 1 according to this embodiment, the lid lock device 82, the connector lock device 83, and the lid lock device 87 are connected to a common relay box 160 and receive operating power through the relay box 160.

[0056] 4, lock relay 101 includes contact 101a and coil 101b. When coil 101b is excited, contact 101a operates to connect electric wire L4 to power supply node 510. When coil 101b is de-excited, contact 101a operates to connect electric wire L4 to body earth 520. Coil 101b is connected to body ECU 65 via signal line S1, and is switched between excited and de-excited states by body ECU 65. Note that, hereinafter, a state in which electric wire L4 is connected to power supply node 510 will be referred to as lock relay 101 being ON, and a state in which electric wire L4 is connected to body earth 520 will be referred to as lock relay 101 being OFF.

[0057] The unlock relay 103 includes a contact 103a and a coil 103b. When the coil 103b is excited, the contact 103a operates to connect the electric wire L5 to the power supply node 510. When the coil 103b is de-excited, the contact 103a operates to connect the electric wire L5 to the body earth 520. The coil 103b is connected to the body ECU 65 via a signal line S2, and is switched between excited and de-excited by the body ECU 65. Note that, hereinafter, a state in which the electric wire L5 is connected to the power supply node 510 will be referred to as the unlock relay 103 being ON, and a state in which the electric wire L5 is connected to the body earth 520 will be referred to as the unlock relay 103 being OFF.

[0058] The lid lock device 82, the connector lock device 83, and the lid lock device 87 are connected in parallel to one another between the electric wire L4 and the electric wire L5.

[0059] As described above, the lid lock device 82 includes the lock pin 82a and the drive device 82b. The drive device 82b includes, for example, a motor and is connected between the electric wires L4 and L5. The motor included in the drive device 82b rotates forward when a current (lock current) flows from the electric wire L4 to the electric wire L5 through the motor, and rotates reversely when a current (unlock current) flows from the electric wire L5 to the electric wire L4 through the motor. When the motor rotates forward, the drive device 82b advances the lock pin 82a, transitioning the lid lock device 82 from an unlocked state to a locked state. When the motor rotates reversely, the drive device 82b retracts the lock pin 82a, transitioning the lid lock device 82 from a locked state to a unlocked state.

[0060] As described above, the connector locking device 83 includes the lock pin 83a and the drive device 83b. The drive device 83b includes, for example, a motor and is connected between the electric wires L4 and L5. The motor included in the drive device 83b rotates forward when a current (lock current) flows from the electric wire L4 to the electric wire L5 through the motor, and rotates reversely when a current (unlock current) flows from the electric wire L5 to the electric wire L4 through the motor. When the motor rotates forward, the drive device 83b advances the lock pin 83a, transitioning the connector locking device 83 from an unlocked state to a locked state. When the motor rotates reversely, the drive device 83b retracts the lock pin 83a, transitioning the connector locking device 83 from a locked state to a unlocked state.

[0061] The connector locking device 83 may further include a lock detection switch 83c that detects the transition of the connector locking device 83 to a locked state. The lock detection switch 83c is connected to the body ECU 65 through a signal line S3. For example, the lock detection switch 83c is pressed by the lock pin 83a that has transitioned to the locked state position, and is turned ON. For example, when the lock pin 83a transitions from the locked state position to the unlocked state position, the lock detection switch 83c is no longer pressed by the lock pin 83a, and is turned OFF. The body ECU 65 detects the state of the connector locking device 83, for example, based on the voltage level of the signal line S3.

[0062] As described above, the lid lock device 87 includes the lock pin 87a and the drive device 87b. The drive device 87b includes, for example, a motor and is connected between the electric wires L4 and L5. The motor included in the drive device 87b rotates forward when a current (lock current) flows from the electric wire L4 to the electric wire L5 through the motor, and rotates reversely when a current (unlock current) flows from the electric wire L5 to the electric wire L4 through the motor. When the motor rotates forward, the drive device 87b advances the lock pin 87a, transitioning the lid lock device 87 from an unlocked state to a locked state. When the motor rotates reversely, the drive device 87b retreats the lock pin 87a, transitioning the lid lock device 87 from a locked state to a unlocked state.

[0063] In vehicle 1 according to this embodiment, for the locking operation, lid lock device 82, connector lock device 83, and lid lock device 87 receive operating power through a common lock relay 101. For the unlocking operation, lid lock device 82, connector lock device 83, and lid lock device 87 receive operating power through a common unlock relay 103.

[0064] <Linked / non-linked with door lock command / door unlock command> In the vehicle 1 according to this embodiment, the body ECU 65 determines whether to link the door lock command and the door unlock command with the control of the relay box 160, based on the open / closed state of the DC lid 47. The body ECU 65 detects the open / closed state of the DC lid 47 based on the lid signal K2 received via the charging ECU 60.

[0065] When the DC lid 47 is in the closed state, the body ECU 65 controls the relay box 160 (lock relay 101 and unlock relay 103) in response to a door lock command or a door unlock command. When the body ECU 65 receives a door lock command while the DC lid 47 is closed (closed state), it turns on the lock relay 101 in addition to the lock relay 100. Specifically, in response to the door lock command, the body ECU 65 turns on the lock relay 100 and turns off the unlock relay 102, and also turns on the lock relay 101 and turns off the unlock relay 102. As a result, the door lock device 80 is locked, and the lid lock device 82, the connector lock device 83, and the lid lock device 87 are also locked.

[0066] When the body ECU 65 receives a door unlock command while the DC lid 47 is closed (closed state), it turns on the unlock relay 103 in addition to the unlock relay 102. Specifically, in response to the door unlock command, the body ECU 65 turns "the lock relay 100 OFF and the unlock relay 102 ON" and also turns "the lock relay 101 OFF and the unlock relay 102 ON." As a result, the door lock device 80 enters the unlocked state, and the lid lock device 82, the connector lock device 83, and the lid lock device 87 also enter the unlocked state.

[0067] When the DC lid 47 is open, the body ECU 65 does not link control of the relay box 160 with a door lock command. When the body ECU 65 receives a door lock command while the DC lid 47 is open (open state), it turns the lock relay 100 ON and the unlock relay 102 OFF in response to the door lock command, but maintains the lock relay 101 OFF and the unlock relay 103 OFF until DC charging starts. Once DC charging starts, the body ECU 65 turns the lock relay 101 ON and the unlock relay 103 OFF until DC charging is completed (i.e., while DC charging is being performed). Once DC charging is completed, the body ECU 65 turns the lock relay 101 OFF and the unlock relay 103 ON. As a result, the door lock device 80 is locked in response to the door lock command, and the lid lock device 82, the connector lock device 83, and the lid lock device 87 are locked only while DC charging is being performed. By locking the lid lock device 82, the connector lock device 83, and the lid lock device 87 while DC charging is being performed, it is possible to prevent tampering with the AC lid 42 and the power receiving port unit 40 while DC charging is being performed.

[0068] In addition, when the transition of the lid lock device 82, the connector lock device 83, and the lid lock device 87 to the locked state or the unlocked state is completed, the body ECU 65 turns "the lock relay 101 OFF and the unlock relay 103 OFF" to maintain the lock pins 82a, 83a, and 87a of the lid lock device 82, the connector lock device 83, and the lid lock device 87, respectively, in the locked state or the unlocked state position.

[0069] <Timing chart> FIG. 5 is a timing chart of a comparative example. The above configuration makes it possible to avoid situations such as those described in the comparative example below. In the vehicle of the comparative example, the lock relay and unlock relay of the door lock device 80, the lid lock device 82, the connector lock device 83, and the lid lock device 87 are shared. In the vehicle of the comparative example, the lock relay and the unlock relay are controlled in response to a door lock command and a door unlock command. In other words, in the vehicle of the comparative example, the door lock device 80, the lid lock device 82, the connector lock device 83, and the lid lock device 87 are controlled so as to be constantly interlocked with each other.

[0070] Referring to FIG. 5, a user's operation related to DC charging (charging operation), the state of the lid lock device 87, the open / closed state of the DC lid 47, and an image of the DC lid 47 being locked are shown.

[0071] First, assume that the vehicle is parked with the DC lid 47 closed. At time t1, the user opens the DC lid 47. Then, the user connects the connector 320 of the DC charging equipment 300 to the DC inlet 46 and performs a door lock operation to lock the access door at time t2. In response to this door lock operation, a door lock command is sent from the verification ECU 70 to the body ECU 65. In response to the door lock command, the body ECU 65 transitions not only the door lock device 80 but also the lid lock device 82, the connector lock device 83, and the lid lock device 87 to a locked state. Therefore, the lock pin 87a of the lid lock device 87 advances, and the advanced lock pin 87a prevents the DC lid 47 from being closed.

[0072] At time t3, the user performs a start operation to start DC charging, which activates the connector locking device of DC charging equipment 300, and the connection between DC inlet 46 and connector 320 becomes locked.

[0073] At time t4, when DC charging is completed, the connection between the DC inlet 46 and the connector 320 is unlocked, and the connector 320 is removed from the DC inlet 46.

[0074] At time t5, the user attempts to close the DC lid 47. However, because the lid lock device 87 is in the locked state, the lock pin 87a prevents the user from closing the DC lid 47, preventing the user from closing the DC lid 47. To unlock the lid lock device 87, an operation to unlock the boarding / exiting door is required. Requiring a separate operation to close the DC lid 47 reduces user convenience.

[0075] Fig. 6 is a timing chart of this embodiment. Similar to Fig. 5, Fig. 6 shows the user's operation related to DC charging (charging operation), the state of the lid lock device 87, the open / closed state of the DC lid 47, and an image of the lock of the DC lid 47.

[0076] First, assume that the vehicle 1 is parked with the DC lid 47 closed. At time t10, the user opens the DC lid 47. Then, the user connects the connector 320 of the DC charging equipment 300 to the DC inlet 46 and performs a door lock operation to lock the access door at time t11. In response to this door lock operation, a door lock command is sent from the verification ECU 70 to the body ECU 65. In response to the door lock command, the body ECU 65 transitions the door lock device 80 to a locked state. However, the body ECU 65 leaves the lid lock device 82, the connector lock device 83, and the lid lock device 87 in an unlocked state. In other words, the door lock operation does not transition the lid lock device 87 to a locked state. Therefore, at this stage, the user can close the DC lid 47.

[0077] At time t12, the user performs a start operation to start DC charging. This causes the body ECU 65 to lock the lid lock device 82, the connector lock device 83, and the lid lock device 87. Additionally, a connector lock device (not shown) of the DC charging equipment 300 is activated, locking the connection between the DC inlet 46 and the connector 320. While DC charging is being performed, the lid lock device 82 also enters the locked state. This prevents the AC lid 42 from being opened while DC charging is being performed, thereby preventing tampering with the AC lid 42 and the power receiving port unit 40 while DC charging is being performed.

[0078] At time t13, DC charging is completed. Upon completion of DC charging, a connector locking device (not shown) of DC charging equipment 300 is activated, and the connection between DC inlet 46 and connector 320 is unlocked. Then, the user removes connector 320 from DC inlet 46.

[0079] Furthermore, upon completion of DC charging, the body ECU 65 transitions the lid lock device 82, the connector lock device 83, and the lid lock device 87 to an unlocked state. This allows the user who has removed the connector 320 from the DC inlet 46 to close the DC lid 47 at time t14.

[0080] <Flowchart> 7 is a flowchart showing an example of a procedure of processing executed in response to a door lock command. The processing of this flowchart is started by the body ECU 65 when the door lock command is received from the verification ECU 70. Note that, although each step (hereinafter, step is abbreviated as "S") of the flowchart shown in FIG. 7 will be described as being implemented by software processing by the body ECU 65, some or all of the steps may also be implemented by hardware (electrical circuits) created within the body ECU 65.

[0081] In S1, the body ECU 65 determines whether the DC lid 47 is open or not based on the detection result of the lid switch 86. The body ECU 65 may receive the lid signal K2 via the charging ECU 60 and determine whether the DC lid 47 is open or not based on the lid signal K2, or may determine whether the DC lid 47 is open or not based on the open / closed state of the DC lid 47 determined by the charging ECU 60 upon receiving the lid signal K2 from the lid switch 86. If the body ECU 65 determines that the DC lid 47 is open (YES in S1), the process proceeds to S3. If the body ECU 65 determines that the DC lid 47 is not open (NO in S1), the process proceeds to S13.

[0082] In S3, the body ECU 65 keeps the lock relay 101 and the unlock relay 103 OFF. That is, the body ECU 65 keeps the lid lock device 82, the connector lock device 83, and the lid lock device 87 in the unlocked state. In response to a door lock command, the body ECU 65 turns the lock relay 100 ON and the unlock relay 102 OFF, thereby putting the door lock device 80 into the locked state and locking the entry / exit doors.

[0083] In S5, the body ECU 65 determines whether DC charging has started. Whether DC charging has started is communicated to the body ECU 65 by the charging ECU 60. For example, when the user presses a charging start button provided on the DC charging equipment 300, communication is established between the DC charging equipment 300 and the charging ECU 60. The body ECU 65 may detect the start of DC charging by the charging ECU 60 communicating this communication establishment to the body ECU 65. If the body ECU 65 determines that DC charging has not started (NO in S5), it waits for DC charging to start. The user can close the DC lid 47 until DC charging starts. If the body ECU 65 determines that DC charging has started (YES in S5), it proceeds to S7.

[0084] In S7, the body ECU 65 turns on the lock relay 101 and turns off the unlock relay 103 to lock the lid lock device 82, the connector lock device 83, and the lid lock device 87. As a result, the lid lock device 82 of the AC lid 42 is also locked during DC charging, making it impossible to open the AC lid 42. This makes it possible to prevent tampering with the AC lid 42 and the power receiving port unit 40 during DC charging.

[0085] In S9, the body ECU 65 determines whether or not DC charging has been completed. DC charging is terminated when a condition is met. The condition may be, for example, at least one of the following: the power storage device 10 is fully charged; the SOC (State Of Charge) of the power storage device 10 has reached a set SOC; a set charging time has elapsed; and a charging end button provided on the DC charging equipment 300 has been pressed. The body ECU 65 waits for DC charging to be completed (NO in S9). When DC charging is completed (YES in S9), the body ECU 65 advances the process to S11.

[0086] In S11, the body ECU 65 turns the lock relay 101 OFF and turns the unlock relay 103 ON to unlock the lid lock device 82, the connector lock device 83, and the lid lock device 87. This allows the user to remove the connector 320 from the DC inlet 46 and close the DC lid 47.

[0087] In S13, the body ECU 65 turns on the lock relay 101 and turns off the unlock relay 103 to lock the lid lock device 82, the connector lock device 83, and the lid lock device 87. It is assumed that DC charging will not be performed if the DC lid 47 is not open. Therefore, the body ECU 65 locks the lid lock device 82, the connector lock device 83, and the lid lock device 87 in response to a door lock command. In response to the door lock command, the body ECU 65 also locks the door lock device 80 by turning on the lock relay 100 and turning off the unlock relay 102.

[0088] In S15, the body ECU 65 determines whether or not a door unlock command has been received from the verification ECU 70. If the body ECU 65 determines that a door unlock command has not been received (NO in S15), the body ECU 65 waits for reception of the door unlock command. If the body ECU 65 determines that a door unlock command has been received (YES in S15), the process proceeds to S17.

[0089] In S17, the body ECU 65 turns "the lock relay 101 OFF and the unlock relay 103 ON" to unlock the lid lock device 82, the connector lock device 83, and the lid lock device 87. In response to the door unlock command, the body ECU 65 turns "the lock relay 100 OFF and the unlock relay 102 ON" to also unlock the door lock device 80.

[0090] As described above, in the vehicle 1 according to the present embodiment, when the DC lid 47 is in the closed state, the control of the relay box 160 (the lock relay 101 and the unlock relay 103) is linked to the door lock command, whereas when the DC lid 47 is in the open state, the control of the relay box 160 (the lock relay 101 and the unlock relay 103) is not linked to the door lock command. It is assumed that DC charging is not performed when the DC lid 47 is in the closed state. In this case, the door lock device 80, the lid lock device 82, the connector lock device 83, and the lid lock device 87 are all locked in response to the door lock operation, thereby improving user convenience.

[0091] On the other hand, when the DC lid 47 is in the open state, it is assumed that DC charging will be performed. In this case, if the control of the relay box 160 is linked to the door lock command, a separate operation (an operation to unlock the entry / exit door) is required to close the DC lid 47 after DC charging is completed, which reduces user convenience. Therefore, by not linking the control of the relay box 160 to the door lock command, it is possible to prevent the user convenience from being reduced.

[0092] In vehicle 1 according to the present embodiment, when DC lid 47 is open, lid lock device 87 is kept unlocked until DC charging starts, kept locked while DC charging is in progress, and unlocked when DC charging is complete. Because lid lock device 87 is unlocked when DC charging is complete, the user can close DC lid 47 without any additional operation.

[0093] Furthermore, the lid lock device 82 is also locked while DC charging is being performed. That is, the AC lid 42 cannot be opened while DC charging is being performed, which makes it possible to prevent tampering with the AC lid 42 and the power receiving port unit 40 while DC charging is being performed.

[0094] Furthermore, in vehicle 1 according to this embodiment, a common relay is used to switch between supplying and cutting off operating power to each of lid lock device 82, connector lock device 83, and lid lock device 87. Therefore, there is no need to provide individual relays to switch between supplying and cutting off operating power to each of lid lock device 82, connector lock device 83, and lid lock device 87, and therefore the circuit can be configured at low cost.

[0095] [Variations] In the embodiment, an example has been described in which the lid lock device 82, the connector lock device 83, and the lid lock device 87 each include a lock pin and a drive device as their mechanism. However, the mechanisms of the lid lock device 82, the connector lock device 83, and the lid lock device 87 are not limited to those described above. Various known mechanisms can be used for the lid lock device 82, the connector lock device 83, and the lid lock device 87.

[0096] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present disclosure is defined by the claims, not by the description of the above embodiments, and is intended to include all modifications within the meaning and scope of the claims.
