[0010] <1. Vehicle Overview> Figure 1 is a diagram showing the general configuration of vehicle 1. Vehicle 1 is an electric vehicle or a plug-in hybrid vehicle that can charge a battery 14 (see Figure 2) from a charger 2, which is an external charging device. Vehicle 1 travels by supplying electricity stored in battery 14 to a drive motor, which is a power source, to drive the vehicle.

[0011] Vehicle 1 charges battery 14 with DC current supplied from charger 2. Charger 2 is equipped with a power transmission cable 3, and a charging gun 4 is attached to the end of power transmission cable 3. Charger 2 supplies DC current via power transmission cable 3 to vehicle 1 into which charging gun 4 is inserted.

[0012] The vehicle 1 is provided with two inlets 11 and two lids 12 for opening and closing the inlets 11, respectively. Although details will be described later, the inlet 11 is provided with a lid lock mechanism 18 (see FIG. 2), and the user can open the lid 12 by unlocking the lid lock mechanism 18. When the user opens the lid 12, the inlet 11 is released.

[0013] The vehicle 1 can charge the battery 14 by inserting one charging gun 4 into one inlet 11 and receiving a supply of DC current from one charger 2. The vehicle 1 can also charge the battery 14 by inserting two charging guns 4 into both inlets 11, respectively, and receiving a supply of DC current from two chargers 2 simultaneously.

[0014] Here, we will explain the case where one charger 2 is provided with one power transmission cable 3 and one charging gun 4, but one charger 2 may also be provided with multiple power transmission cables 3 and multiple charging guns 4.

[0015] In the following description, when the two inlets 11 are to be distinguished from one another, they may be referred to as a first inlet 11a and a second inlet 11b. The lid 12 that opens and closes the first inlet 11a may be referred to as a first lid 12a, and the lid 12 that opens and closes the second inlet 11b may be referred to as a second lid 12b.

[0016] <2. Configuration of Vehicle 1 and Charger 2> Fig. 2 is a diagram showing the configuration of vehicle 1 and charger 2. In Fig. 2, electrical wiring is shown by solid lines, signal flows are shown by dashed lines, and signal lines for data communication are shown by dashed lines.

[0017] As shown in Figure 2, the power transmission cable 3 of the charger 2 includes two electric wires 3a and 3b for supplying direct current, and a signal wire 3c for performing data communication in accordance with a predetermined in-vehicle network communication standard such as CAN (Controller Area Network).

[0018] The charging gun 4 is provided with a charging gun locking mechanism 5. The charging gun locking mechanism 5 includes, for example, a hook that can protrude when the charging gun 4 is inserted into the inlet 11, and a solenoid that can restrict the movement of the hook when it is protruded. When the charging gun 4 is inserted into the inlet 11, the hook protrudes and engages with the inlet 11. With the hook engaged with the inlet 11, the solenoid is energized and the movement of the hook is restricted. This allows the charging gun locking mechanism 5 to lock the charging gun 4 to the inlet 11. When the solenoid is de-energized, the hook is retractable, allowing the charging gun locking mechanism 5 to unlock the charging gun 4 from the inlet 11.

[0019] The vehicle 1 includes two inlets 11, two lids 12, one contactor 13, a battery 14, a BCU (Battery Control Unit) 15, and two inlet opening switches 16.

[0020] The inlet 11 is provided with a state detection sensor 17 that detects the insertion of the charging gun 4, the opening of the inlet 11, and the closing of the lid 12. When the state detection sensor 17 detects the insertion of the charging gun 4, the opening of the inlet 11, or the closing of the lid 12, it outputs the detection result to the BCU 15 as an inlet state detection signal D1.

[0021] The inlet 11 is also provided with a lid lock mechanism 18 that locks the lid 12 to the housing of the vehicle 1 to prevent the inlet 11 from being opened. The lid lock mechanism 18 is locked and unlocked under the control of the BCU 15.

[0022] The contactor 13 is connected between the two inlets 11 and the battery 14. Specifically, the two inlets 11 are connected in parallel to one end of the contactor 13, and the battery 14 is connected to the other end. The contactor 13 is turned on and off under the control of the BCU 15. When the contactor 13 is turned off, the two inlets 11 and the battery 14 are disconnected, and when the contactor 13 is turned on, the two inlets 11 and the battery 14 are connected.

[0023] The battery 14 is a so-called high-voltage battery, and is capable of storing electricity (power) to be supplied to the drive motor.

[0024] The BCU 15 is a processor including a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The BCU 15 controls each part related to the battery 14 by expanding a program stored in the ROM onto the RAM and executing the program.

[0025] The BCU 15 is connected to two inlets 11, one contactor 13, and two inlet opening switches 16. The BCU 15 receives an inlet state detection signal D1 output from a state detection sensor 17. The BCU 15 also transmits a lid lock signal D2 to the lid lock mechanism 18 (inlets 11) to instruct the lid 12 to lock or unlock. The BCU 15 also transmits a contactor drive signal D3 to the contactor 13 to switch the contactor 13 on and off. The BCU 15 also receives an inlet opening request signal D4 from the inlet opening switch 16, indicating that the inlet opening switch 16 has been operated.

[0026] Furthermore, the BCU 15 and the inlet 11 are connected by a signal line 19 that enables data communication in accordance with a predetermined in-vehicle network communication standard such as CAN. When the charging gun 4 is inserted into the inlet 11, the signal line 3c is connected to the signal line 19. This enables the BCU 15 to communicate data with the charger 2 via the signal line 3c and the signal line 19. In data communication, for example, when the charging gun 4 is inserted into the inlet 11, a charging gun lock signal D5 is sent from the BCU 15 to the charger 2 to instruct the charging gun 4 to lock or unlock. In addition, a command value signal D6 is sent from the BCU 15 to the charger 2 to instruct the current value and voltage value during charging.

[0027] The inlet opening switch 16 is provided, for example, inside the vehicle or near the inlet 11, and receives an operational input to request the opening of the inlet 11. Here, opening the inlet 11 includes opening the lid 12 to open the inlet 11 when the lid 12 is closing the inlet 11, and removing the charging gun 4 when the charging gun 4 is inserted into the inlet 11 to open the inlet 11. The inlet opening switch 16 that accepts operational input to open the first inlet 11a may be referred to as the first inlet opening switch 16a, and the inlet opening switch 16 that accepts operational input to open the second inlet 11b may be referred to as the second inlet opening switch 16b.

[0028] <3. State transition and flow of charging process> Fig. 3 is a diagram showing a change from charging using one charger 2 to charging using two chargers 2. Fig. 4 is a diagram showing a change from charging using two chargers 2 to charging using one charger 2.

[0029] Incidentally, since the vehicle 1 is equipped with two inlets 11, it is possible to change from charging using one charger 2 to charging using two chargers 2, or from charging using two chargers 2 to charging using one charger 2.

[0030] For example, as shown in the upper part of Fig. 3, suppose that two different vehicles 1 are each charging using one charger 2. Then, as shown in the middle part of Fig. 3, suppose that charging of one vehicle 1 finishes and one charger 2 becomes available. In such a case, as shown in the lower part of Fig. 3, the other vehicle 1 that is currently charging continues charging using the available charger 2, i.e., using two chargers 2.

[0031] Also, as shown in the upper part of FIG. 4, suppose one vehicle 1 is being charged using two chargers 2. Then, as shown in the middle part of FIG. 4, suppose a different vehicle 1 approaches one charger 2 to charge. In such a case, as shown in the lower part of FIG. 4, the vehicle 1 that was being charged using two chargers 2 removes the charging gun 4 from one of the chargers 2 and switches to charging using one charger 2. Then, the other vehicle 1 inserts the removed charging gun 4 and begins charging using one charger 2. As a result, the two vehicles 1 are each being charged using one charger 2.

[0032] In this way, it is assumed that the vehicle 1 switches between charging using one charger 2 and charging using two chargers 2 during charging. The following describes the state transition and control flow of the charging process when switching between charging using one charger 2 and charging using two chargers 2 during charging.

[0033] 5 is a diagram showing state transitions during the charging process. As shown in FIG. 5, when the charging process starts, the state transitions to a first standby state (1). In the first state, the first state continues until the inlet opening switch 16 is operated by the user and an inlet opening request signal D4 is input to the BCU 15 (2).

[0034] In the first state, when the inlet opening switch 16 is operated by a user and an inlet opening request signal D4 is input to the BCU 15, the process shifts to the first process (3), and the BCU 15 executes the first process (inlet unlock process). In the first process, the BCU 15 transmits a lid lock signal D2 that instructs the unlocking of the lid 12 corresponding to the inlet opening switch 16 that transmitted the inlet opening request signal D4, and transitions to the second state (4) in which the BCU 15 waits for the inlet 11 to close. In the second state, the inlet 11 corresponding to the inlet opening switch 16 that transmitted the inlet opening request signal D4 can be opened.

[0035] The second state continues until an inlet state detection signal D1 is input from the state detection sensor 17 of the openable inlet 11 in the second state (5). When the inlet state detection signal D1 indicating that the lid 12 is closed is input to the BCU 15 from the state detection sensor 17 of the openable inlet 11, a transition to the first state occurs (6).

[0036] When the inlet state detection signal D1 indicating that the charging gun 4 has been inserted into the inlet 11 is input to the BCU 15, the process proceeds to the second process (7), and the BCU 15 executes the second process (charging start process). In the second process, the BCU 15 locks the inlet 11. Here, locking the inlet 11 includes transmitting a charging gun lock signal D5 that instructs the charging gun 4 to be locked so that the inserted charging gun 4 cannot be removed, and transmitting a lid lock signal D2 that instructs the lid 12 to be locked so that the lid 12 cannot be opened. Furthermore, the BCU 15 transmits a contactor drive signal D3 to the contactor 13 to turn on the contactor 13. Then, the BCU 15 transmits a command value signal D6 indicating a current value and a voltage value to the charger 2, and transitions to the third state (8). When the current value and voltage value are specified, the charger 2 starts charging the battery 14 by supplying a direct current of the specified current value and voltage value to the vehicle 1.

[0037] In the third state, when the inlet opening switch 16 is operated by the user and an inlet opening request signal D4 is input to the BCU 15, the process proceeds to the third process (9), and the BCU 15 executes the third process (charging stop process). In this case, the process proceeds to the third process when the user operates the inlet opening switch 16 to switch charging from two chargers 2 to one charger 2, or from one charger 2 to two chargers 2.

[0038] In the third process, the BCU 15 transmits a command value signal D6 to the charger 2 to cause the current value and voltage value to drop to zero (prescribed value), thereby causing the current value and voltage value of the direct current flowing through the contactor 13 to drop to zero. After that, the BCU 15 transmits a contactor drive signal D3 to the contactor 13 to turn off the contactor 13. The BCU 15 also unlocks the inlet 11 corresponding to the inlet opening switch 16 operated by the user, and transitions to the fourth state (10). Here, unlocking the inlet 11 includes sending a charging gun lock signal D5 that instructs the charging gun 4 to be unlocked so that the inserted charging gun 4 can be removed, and sending a lid lock signal D2 that instructs the lid 12 to be unlocked so that it can be opened.

[0039] The fourth state continues until the inlet 11 is opened (11). When the inlet state detection signal D1 indicating that the inlet 11 is opened is input to the BCU 15 in the fourth state, the state transitions to the second state (12). Furthermore, when a predetermined time has elapsed since the inlet 11 was opened, the state transitions to a fourth process (error notification process) (13). In the fourth process, the BCU 15 notifies the user that the inlet 11 is not opened. Here, for example, a display may be displayed on a display unit provided in the vehicle 1, or a sound may be output from a speaker provided in the vehicle 1.

[0040] After performing the fourth process, the BCU 15 may end the charging process, or may transition to the second process (14), or may transition to the third process (15).

[0041] Furthermore, when the charge termination condition is satisfied in the third state, the process proceeds to a fifth process, and the BCU 15 performs the fifth process (charge termination process) (16). In the fifth process, the BCU 15 transmits a command value signal D6 to the charger 2 to cause the current value and voltage value to droop to zero, and causes the current value and voltage value of the direct current flowing through the contactor 13 to droop to zero. Thereafter, the BCU 15 transmits a contactor drive signal D3 to the contactor 13 to turn off the contactor 13. The BCU 15 also sends a charging gun lock signal D5 to the charger 2 to instruct the charger 2 to unlock the charging gun 4 so that the inserted charging gun 4 can be removed, and notifies the user that charging has finished and the charging gun 4 can be removed. When the charging gun 4 is removed and the lid 12 is closed, the BCU 15 sends a lid lock signal D2 to instruct the charger 2 to lock the lid 12.

[0042] In this state transition, when charging is changed from using one charger 2 to using two chargers 2, the system goes through the first state, first process, second state, and second process, and then to the third state where the charging gun 4 is inserted into one inlet 11 and charging begins using one charger 2. In this state, when the inlet opening switch 16 corresponding to the inlet 11 that is not being charged is operated and an inlet opening request signal D4 is input to the BCU 15, the system moves to the third process (9). In the third process, the BCU 15 turns off the contactor 13 after causing the current and voltage values ​​of the DC current flowing through the contactor 13 to drop to zero, and then unlocks the lid 12 to make the inlet 11 openable (10).

[0043] Then, when the charging gun 4 is inserted into the inlet 11 after the lid 12 is opened and an inlet state detection signal D1 indicating that the charging gun 4 has been inserted is input to the BCU 15, the process proceeds to the second process (12), (7), and the BCU 15 executes the second process (charging start process). Here, the BCU 15 locks the charging gun 4 inserted into the inlet 11, and then turns on the contactor 13 to resume (start) charging using the two chargers 2.

[0044] On the other hand, when changing from charging using two chargers 2 to charging using one charger 2, charging using two chargers 2 is performed in the third state. In this state, when the inlet opening switch 16 corresponding to the inlet 11 from which the charging gun 4 is to be removed is operated and an inlet opening request signal D4 is input to the BCU 15, the process moves to the third process (9). In the third process, the BCU 15 turns off the contactor 13 after causing the current and voltage values ​​of the DC current flowing through the contactor 13 to drop to zero, and then unlocks the charging gun 4 (10).

[0045] Then, when the lid 12 is closed after the charging gun 4 is removed and an inlet state detection signal D1 indicating that the lid 12 is closed is input to the BCU 15, the process proceeds to the second process (12), (7), and the BCU 15 executes the second process (charging start process). Here, the BCU 15 locks the closed lid 12 and then turns on the contactor 13, and charging using one charger 2 is resumed.

[0046] Fig. 6 is a flowchart showing the flow of the charging process. As shown in Fig. 6, when the charging process starts, the BCU 15 determines whether the inlet opening switch 16 has been operated by the user and an inlet opening request signal D4 has been input. Then, the BCU 15 repeats step S1 until the inlet opening request signal D4 is input (No in step S1).

[0047] When the inlet open request signal D4 is received (Yes in step S1), in step S2 the BCU 15 sends a lid lock signal D2 instructing the unlocking of the lid 12 that closes the inlet 11 corresponding to the inlet open switch 16 that sent the inlet open request signal D4.

[0048] Thereafter, in step S3, the BCU 15 determines whether or not an inlet state detection signal D1 indicating that the lid 12 is closed has been input. If an inlet state detection signal D1 indicating that the lid 12 is closed has been input (Yes in step S3), the BCU 15 returns the process to step S1.

[0049] On the other hand, if the inlet state detection signal D1 indicating that the lid 12 is closed has not been input (No in step S3), the BCU 15 determines in step S4 whether the inlet state detection signal D1 indicating that the charging gun 4 has been inserted has been input. If the inlet state detection signal D1 indicating that the charging gun 4 has been inserted has not been input (No in step S4), the BCU 15 returns the process to step S3.

[0050] If the inlet state detection signal D1 indicating that the charging gun 4 has been inserted is input (Yes in step S4), the BCU 15 executes charging start processing in step S5. Here, the BCU 15 locks the charging gun 4 inserted into the inlet 11, and outputs a contactor drive signal D3 to the contactor 13 to turn on the contactor 13. The BCU 15 then performs data communication with the charger 2 to specify a voltage value and a current value. When the voltage value and current value have been specified, the charger 2 supplies DC current of the specified voltage value and current value to the vehicle 1.

[0051] Then, in step S6, the BCU 15 determines whether the inlet open switch 16 has been operated by the user and an inlet open request signal D4 has been input. If the inlet open request signal D4 has not been input (No in step S6), the BCU 15 determines in step S7 whether a charging termination condition has been met. The BCU 15 repeats steps S6 and S7 until the inlet open request signal D4 is input or the charging termination condition is met.

[0052] If the charge termination condition is met (Yes in step S7), the BCU 15 executes charge termination processing in step S8. Here, the BCU 15 performs data communication with the charger 2 to cause the voltage and current values ​​to drop to zero, and then sends a contactor drive signal D3 to the contactor 13 to turn off the contactor 13. The BCU 15 also unlocks the inlet 11 into which the charging gun 4 is inserted, and notifies the user that charging has ended and the charging gun 4 can be removed. Then, when the charging gun 4 is removed and the lid 12 is closed, the BCU 15 locks the lid 12 of the inlet 11.

[0053] On the other hand, when the inlet opening request signal D4 is input (Yes in step S6), the BCU 15 performs charging stop processing in step S9. Here, the BCU 15 performs data communication with the charger 2 to cause the voltage and current values ​​to drop to zero, and then sends a contactor drive signal D3 to the contactor 13 to turn off the contactor 13. The BCU 15 also unlocks the inlet 11 corresponding to the inlet opening switch 16 operated by the user.

[0054] Then, in step S10, the BCU 15 determines whether or not an inlet state detection signal D1 indicating that the inlet 11 has been opened has been input. If the inlet state detection signal D1 indicating that the inlet 11 has been opened has not been input (No in step S10), the BCU 15 determines whether or not a predetermined time has elapsed in step S11. The BCU 15 repeats steps S10 and S11 until an inlet state detection signal D1 indicating that the inlet 11 has been opened is input or the predetermined time has elapsed.

[0055] If the inlet state detection signal D1 indicating that the inlet 11 is opened is input (Yes in step S10), the BCU 15 returns the process to step S3. Also, if a predetermined time has elapsed (Yes in step S11), the BCU 15 notifies the user in step S12 that the inlet 11 is not opened.

[0056] <4. Modifications> Although the embodiments of the present invention have been described above, the present invention is not limited to the specific examples described above and can adopt various configurations. For example, the program for executing the charging process can be stored in advance in a recording medium built into a device such as a computer device, or in a ROM or the like in a microcomputer having a CPU.

[0057] In the above-described embodiment, the vehicle 1 is provided with two inlets 11. However, the vehicle 1 may be provided with a plurality of inlets 11, and may be provided with three or more inlets 11.

[0058] In the above-described embodiment, the lid lock mechanism 18 and the charging gun lock mechanism 5 are provided. However, as long as the lid lock mechanism 18 and the charging gun lock mechanism 5 can lock and unlock the lid 12 and the charging gun 4, one mechanism may serve the other, and the other mechanism may not be provided.

[0059] Furthermore, in the above embodiment, the charging gun locking mechanism 5 is provided on the charging gun 4, but the charging gun locking mechanism 5 may also be provided on the vehicle 1.

[0060] <5. Summary of embodiments> As described above, the vehicle 1 of the embodiment includes a plurality of inlets 11 into which charging guns 4 of charging devices (chargers 2) are inserted, one contactor 13 connected between the plurality of inlets 11 and the battery 14, and a control unit (BCU 15) that controls the plurality of charging devices (chargers 2) so that the battery 14 can be charged simultaneously. This allows the vehicle 1 to charge by switching the connected charger 2 depending on the number of available chargers 2. At this time, the vehicle 1 can temporarily turn off the contactor 13 and insert or remove the charging gun 4 without terminating the charging process. In other words, when changing the number of chargers 2, the vehicle 1 does not need to have the user re-input charging settings, etc. Therefore, the vehicle 1 can efficiently charge the battery 14 while improving convenience for the user.

[0061] The device also includes a plurality of lids 12 that respectively cover the plurality of inlets 11, and a lid lock mechanism 18 that locks the opening and closing of the lids 12. When a request is made to open an available inlet 11 when increasing the number of charging devices (chargers 2) to be connected, the control unit (BCU 15) turns off the contactor 13 and then unlocks the lid 12 using the lid lock mechanism 18. The charging gun 4 is inserted into the inlet 11, and after locking the charging gun 4, the contactor 13 is turned on to resume charging. As a result, when the charging gun 4 is inserted into the inlet 11, the exposed inlet 11 is not in a high voltage state, so that leakage current and electric shock can be prevented.

[0062] The device also includes a plurality of lids 12 that respectively cover the plurality of inlets 11, and a lid lock mechanism 18 that locks the opening and closing of the lids 12. When a request is made to open the inlet 11 into which the charging gun 4 is inserted when reducing the number of connected charging devices (chargers 2), the control unit (BCU 15) turns off the contactor 13 and then unlocks the charging gun 4. After the charging gun 4 is removed from the inlet 11, the lid 12 is closed and locked by the lid lock mechanism 18, charging resumes. As a result, when the charging gun 4 is removed, the exposed inlet 11 is not in a high voltage state, thereby preventing leakage of electricity and electric shock.

[0063] Furthermore, the control unit (BCU 15) turns off the contactor 13 after the current value during charging has decreased to a specified value. This prevents the contactor 13 from being turned off in a high voltage and high current state, and allows the contactor 13 to be turned off more safely.

[0064] Furthermore, if a request to open the inlet 11 is made and the inlet 11 is not opened even after a predetermined time has elapsed since the lid 12 or the charging gun 4 was unlocked, the control unit (BCU 15) issues an error notification. This makes it possible to prevent the lid 12 or the charging gun 4 from remaining unlocked for a long period of time. [Explanation of symbols]
