<Overall configuration>
FIG. 1 is an overall configuration diagram of the charging system of the vehicle 1 according to the present embodiment. This charging system is a system for performing external charging to charge the battery 100 mounted on the vehicle 1 by using the electric power supplied from the charging equipment outside the vehicle 1. In the present embodiment, an example will be described in which AC charging is performed as external charging, for example, by using AC power supplied from a charging facility 500 provided at home or the like to charge the battery 100 mounted on the vehicle 1. In the present embodiment, an example in which AC power supplied from a charging facility 500 provided at home or the like is used as an example of AC charging will be described. For example, it is supplied from a public charging facility (charging stand). AC power to be generated may be used. Further, it may be a quick charge by a direct current.

With reference to FIG. 1, the charging system includes a vehicle 1, a charging cable 400, and a charging facility 500.

The charging facility 500 includes an AC power supply 510 and an outlet 520. The outlet 520 is, for example, an AC outlet for general household use.

At the time of AC charging, the charging equipment 500 and the vehicle 1 are connected by a charging cable 400. The charging cable 400 includes an AC power line 440, a charging connector 410 provided at one end of the AC power line 440, a plug 420 provided at the other end of the AC power line 440, and a charging circuit cutoff device provided on the AC power line 440. (Hereinafter, also referred to as “CCID (Charging Circuit Interrupt Device)”) 430 and the like are included. The charging connector 410 is configured to be connectable to the inlet 220 of the vehicle 1. The plug 420 is configured to be connectable to the outlet 520 of the charging equipment 500. The CCID 430 is a circuit for switching the supply and cutoff of electric power from the charging equipment 500 to the vehicle 1.

The vehicle 1 is an electric vehicle that travels by driving a traveling motor (not shown) using the electric power stored in the battery 100. The vehicle 1 may be a vehicle configured to enable external charging of the battery 100, and may be, for example, a fuel cell vehicle or a plug-in hybrid vehicle.

The vehicle 1 includes a battery 100 and an ECU (Electronic Control Unit) 300. Further, the vehicle 1 includes a charging lid 2, a charger 200, and an inlet 220 as a configuration for performing AC charging.

The battery 100 is mounted on the vehicle 1 as a driving power source (that is, a power source) for the vehicle 1. The battery 100 includes a plurality of stacked batteries. The battery is, for example, a secondary battery such as a nickel hydrogen battery or a lithium ion battery. Further, the battery may be a battery having a liquid electrolyte between the positive electrode and the negative electrode, or a battery having a solid electrolyte (all-solid-state battery). The battery 100 may be a DC power source that can be recharged, and a large-capacity capacitor can also be used.

The ECU 300 includes a CPU (Central Processing Unit) (not shown), a memory (not shown), and an input / output buffer (not shown), and inputs a signal from a sensor or the like and outputs a control signal to each device. At the same time, control each device. Note that these controls are not limited to software processing, but can also be constructed and processed by dedicated hardware (electronic circuits).

The inlet 220 is configured so that the charging connector 410 of the charging cable 400 can be connected. The inlet 220 is normally covered with a charging lid 2. When the charging lid 2 is opened, the user can connect the charging connector 410 to the inlet 220. At the time of AC charging, the charging connector 410 is connected to the inlet 220.

The charger 200 converts the AC power received by the inlet 220 into DC power that can be charged to the battery 100 and outputs the AC power to the battery 100. The charger 200 is controlled by the ECU 300.

A lock device 50 is provided in the vicinity of the inlet 220. The lock device 50 has a locked state in which the charging connector 410 (charging cable 400) connected to the inlet 220 cannot be removed from the inlet 220 and an unlocked state in which the charging connector 410 connected to the inlet 220 can be removed from the inlet 220. Is configured to be switchable.

FIG. 2 is a diagram showing a structure around the inlet 220. 3 and 4 are sectional views of III-III in FIG. 2 when the charging connector 410 is connected to the inlet 220. The connection between the charging connector 410 and the inlet 220 and the configuration of the locking device 50 will be described with reference to FIGS. 2 to 4.

A link 411 is provided on the charging connector 410 of the charging cable 400. The link 411 is rotatably attached around the shaft 412, has a convex portion engaged with the protrusion 221 of the inlet 220 at one end, and a push button 415 at the other end. The link 411 is elastically urged with respect to the main body of the charging connector 410 by the spring 414 (see FIGS. 3 and 4).

When the charging connector 410 is inserted into the inlet 220, the convex portion of the link 411 engages with the protrusion 221 of the inlet 220 (see the state of the link 411 and the protrusion 221 in FIG. 3). Therefore, the charging connector 410 cannot be removed from the inlet 220.

A lock device 50 is provided above (near) the inlet 220. As described above, the lock device 50 has a locked state in which the charging connector 410 connected to the inlet 220 cannot be removed from the inlet 220 and an unlocked state in which the charging connector 410 connected to the inlet 220 can be removed from the inlet 220. Is configured to be switchable.

The lock device 50 includes a lock bar 52 that slides in the vertical direction and an electromagnetic actuator 51 that slides the lock bar 52. The lock device 50 is controlled by the ECU 300.

In the locked state, the lock bar 52 is slid downward and fixed at a position in contact with the upper surface of the link 411 (see FIG. 3). As a result, even if the push button 415 is pressed, the rotation of the link 411 is suppressed by the lock bar 52, and the convex portion of the link 411 does not rise and does not come off from the protrusion 221 of the inlet 220. That is, even if the user presses the push button 415, the charging connector 410 cannot be removed from the inlet 220.

In the unlocked state, the lock bar 52 is slid upward and fixed at a position where the rotation of the link 411 is not suppressed (see FIG. 4). As a result, the lock bar 52 does not suppress the rotation of the link 411, so that when the push button 415 is pushed in, the link 411 rotates around the shaft 412, and a convex portion provided at the end opposite to the push button 415. Rise. As a result, the convex portion of the link 411 comes off from the protrusion 221 of the inlet 220, and the charging connector 410 can be removed from the inlet 220. That is, the user can remove the charging connector 410 from the inlet 220 by pressing the push button 415.

When the locking device 50 detects that the charging connector 410 has been inserted into the inlet 220, the actuator 51 moves the lock bar 52 downward, and the charging connector 410 connected to the inlet 220 cannot be removed from the inlet 220. It becomes locked. The insertion of the inlet 220 into the charging connector 410 can be detected, for example, by a CPLT (control pilot) signal, as is well known.

The lock device 50 shifts from the locked state to the unlocked state in response to the operation of a switch provided on the smart key (not shown) of the vehicle. Specifically, since the user shifts the vehicle door from the locked state to the unlocked state, when the smart key switch is operated, the vehicle door shifts from the locked state to the unlocked state in conjunction with the transition. The lock device 50 is in an unlocked state in which the actuator 51 moves the lock bar 52 upward and the charging connector 410 connected to the inlet 220 can be removed from the inlet 220.

The ECU 300 corresponds to the "charge control device" disclosed in the present invention, and as shown in FIG. 5, includes a timer charging unit 310 and a first control unit 320 as its functional units. The timer charging unit 310 executes timer charging to start external charging at a predetermined time based on a user's instruction input via the input device 600. The input device 600 may be a touch panel of a navigation system or a multi-information display, or may be a mobile terminal capable of communicating with the ECU 300.

When the lock device 50 is in the locked state, the first control unit 320 permits the battery 100 to be charged with the electric power received by the inlet 220, and executes external charging. Specifically, when a charging start condition other than that the lock device 50 is in the locked state is satisfied, the CCID 430 is connected using the CPLT signal, power is supplied from the charging facility 500 to the vehicle 1, and charging is performed. The charger 200 charges the battery 100 by converting the AC power received by the inlet 220 into DC power that can be charged to the battery 100. The first control unit 320 stops the external charging when the lock device 50 is in the unlocked state. Specifically, even if the charging start condition other than the lock device 50 is in the locked state is satisfied, if the lock device 50 is in the unlocked state, the CCID 430 is shut off by using the CPLT signal. The supply of electric power from the charging equipment 500 to the vehicle 1 is cut off, and the operation of the charger 200 is stopped to stop the external charging.

If the user operates the smart key to shift the vehicle door from the locked state to the unlocked state and the lock device 50 shifts from the locked state to the unlocked state during the execution of the external charge, the user performs the external charge. It is considered that the vehicle is intended to stop and start running. Therefore, it is desirable that the first control unit 320 stop the external charge when the lock device 50 is in the unlocked state.

However, if the lock device 50 shifts from the locked state to the unlocked state during the execution of timer charging based on the user's instruction, it may be an unintended shift to the unlocked state due to an operation error of the user or the like, or it may be in the vehicle interior. It is highly possible that an unlock operation was performed to remove the misplaced item. Therefore, in the first control unit 320, when the lock device 50 is unlocked during the execution of timer charging, the charging connector 410 is connected to the inlet 220 for a predetermined period from the time when the lock device 50 is unlocked. If so, allow the execution of external charging and restart external charging. As a result, the external charging can be restarted in consideration of the user's intention.

<Processing executed by ECU 300>
FIG. 6 is a flowchart illustrating the charging start time setting executed by the timer charging unit 310. In this flow, when the user selects the timer charging mode in advance by operating the input device 600, that is, when the timer charging is executed based on the user's instruction, the vehicle 1 stops and the inlet 220 It is executed when the charging connector 410 is inserted into the.

When the charging connector 410 is inserted into the inlet 220, the scheduled departure time is displayed on the vehicle display device (not shown) in S10. The scheduled departure time may be a time set in advance by the user by operating the input device 600, the previous departure time is stored in the timer charging unit 310, and the stored previous departure time is read out. It may be displayed as the scheduled departure time.

In the following S20, the user operates the input device 600 to determine whether or not the (new) scheduled departure time has been input. If it is determined that the scheduled departure time has not been entered, the process proceeds to S30, and it is determined whether or not a predetermined time (for example, 3 seconds) has elapsed since the charging connector 410 was inserted into the inlet 220, and the predetermined time has elapsed. If it is determined that it is not, the process proceeds to S20.

When the affirmative judgment is made in S20 and when the affirmative judgment is made in S30, the process proceeds to S40 to set the charging start time. Set the flag Ft to 1. The charging start time is set based on the (new) scheduled departure time input by the user by operating the input device 600 when the affirmative judgment is made in S20, and is displayed when the affirmative judgment is made in S30. The charging start time is set based on the scheduled departure time displayed on the device.

The charging start time is set from the current SOC (State of Charge) of the battery 100, the SOC at the end of external charging (for example, SOC = 90%), the rated output of the charger 200, the scheduled departure time, the electricity charge, and the like. .. Specifically, the charging start time is set so that the external charging is completed by the scheduled departure time (that is, the SOC of the battery 100 is 90% or more) and the electricity charge is as small as possible, for example. , The charging start time is set so that the late-night electricity bill can be used effectively. If the user has not selected the timer charging mode, the flowchart of FIG. 6 is not executed.

FIG. 7 is a flowchart illustrating external charging executed by the timer charging unit 310. This flow is processed at predetermined intervals when the vehicle 1 is stopped and the charging connector 410 is inserted into the inlet 220. First, in S100, it is determined whether or not the charging cable 400 is connected to the vehicle 1. When the charging connector 410 is inserted into the inlet 220, a positive determination is made in S100, the process proceeds to S110, and it is determined whether or not the flag Ft is 1. If the flag Ft is 1 and affirmative judgment is made, the charging start time is set, so the process proceeds to S120 to execute timer charging, and it is determined whether or not the current time has passed from the charging start time. Will be done. If the flag Ft is 0 and a negative judgment is made, the process proceeds to S140.

If it is determined in S120 that the current time has not passed the charging start time (if it is negatively determined), the current routine is terminated. If it is determined in S120 that the current time has passed the charging start time (if it is determined affirmatively), the process proceeds to S130, the flag F indicating that the timer is charging is set to 1, and the process proceeds to S140. move on.

In S140, it is determined whether or not the permission flag Fa is 1. The permission flag Fa is a flag set based on the locked state, the unlocked state, and the like of the lock device 50, and the details will be described later. If it is determined in S140 that the permission flag Fa is 1 (if affirmative), the process proceeds to S150, external charging is permitted, and external charging is executed. Specifically, the CCID 430 is connected using the CPLT signal to supply electric power from the charging facility 500 to the vehicle 1, and the charger 200 can charge the battery 100 with the AC electric power received by the inlet 220. The battery 100 is charged by converting it into DC power.

If a negative determination is made in S140 (when the permission flag Fa is set to 0), the process proceeds to S160 and external charging is stopped. Specifically, the CCID 430 is cut off by using the CPLT signal, the supply of electric power from the charging equipment 500 to the vehicle 1 is cut off, and the operation of the charger 200 is stopped to stop the external charging.

Following S150 and S160, S170 determines whether the current SOC of the battery 100 is greater than or equal to a predetermined value (eg, 90%). The method of acquiring the SOC of the battery 100 may be, for example, a known method of obtaining the SOC from the SOC-OCV curve. If the SOC of the battery 100 is less than a predetermined value, a negative determination is made and the current routine is terminated. If the SOC of the battery 100 is equal to or higher than a predetermined value and a positive judgment is made, the process proceeds to S180.

In S180, the external charging is completed (more specifically, the charging end signal is transmitted to the CCID 430 using the CPLT signal, the CCID 430 is cut off, and the power supply from the charging facility 500 to the vehicle 1 is cut off. , Stop the operation of the charger 200 and stop the external charging), set the flag F, the flag Ft, the flag Fa and the flag FL to 0, and then end this routine.

If a negative judgment is made in S100, the charging connector 410 is disconnected from the inlet 220 in this routine, and the connection between the charging cable 400 and the vehicle 1 is disconnected. Therefore, proceed to S180, end the external charging, and flag. Set F, flag Ft, flag Fa and flag FL to 0 and end the routine.

FIG. 8 is a flowchart showing a process executed by the first control unit 320. This flow is processed at predetermined intervals when the vehicle 1 is stopped and the charging connector 410 is inserted into the inlet 220. First, in S200, it is determined whether or not the lock device 50 is in the locked state. If the lock device 50 is in the locked state and an affirmative determination is made, the process proceeds to S210, the permission flag Fa is set to 1, and this routine is terminated.

If the lock device 50 is in the unlocked state and a negative determination is made in S200, the process proceeds to S220, and it is determined in this routine whether or not the lock device 50 has changed from the locked state to the unlocked state. When the lock device 50 shifts from the locked state to the unlocked state in this routine, a positive judgment is made, the process proceeds to S230, the timer T is activated, and then the process proceeds to S240. If a negative determination is made in S220, the process proceeds to S222, and it is determined whether or not the flag FL is 1. If the flag FL is 0 and a negative judgment is made in S222, the process proceeds to S240, and if the flag FL is 1 and a positive judgment is made in S222, the routine ends.

In S250 following S240, it is determined whether or not the flag F1 is 1. When the flag F1 is 1, the timer charging is being executed, a positive judgment is made, and the process proceeds to S260. In S260, it is determined whether or not the charging cable 400 is connected to the vehicle 1. When the charging connector 410 is inserted in the inlet 220 and the charging cable 400 is connected to the vehicle 1, a positive judgment is made, the process proceeds to S270, and whether the timer T is equal to or higher than a predetermined value (for example, 10 seconds). Whether or not it is judged. The predetermined value corresponds to the predetermined period in the present disclosure.

When S270 is processed for the first time, the timer T is less than a predetermined value, a negative judgment is made, and the current routine is terminated. , S280, the timer T is stopped, the value of the timer T is reset, and the flag Fl is set to 0. After that, the process proceeds to S210, the permission flag Fa is set to 1, and the routine ends.

In S250, when the flag F1 is 0, the timer charging is not being executed, so a negative determination is made, the process proceeds to S290, the timer T is stopped, the value of the timer T is reset, and the flag FL is set to 0. After that, exit this routine. If a negative judgment is made in S260, the charging connector 410 is disconnected from the inlet 220 in this routine, and the connection between the charging cable 400 and the vehicle 1 is disconnected. Therefore, the process proceeds to S290, the timer T is stopped, and the timer T is stopped. After resetting the value of timer T and setting the flag FL to 0, this routine ends.

When the timer charging unit 310 starts the timer charging and the timer charging is being executed, the flag F is set to 1 in S130 of FIG. The first control unit 320 sets the permission flag Fa to 1 in S210 of FIG. 8 when the lock device 50 is in the locked state, and sets the permission flag Fa in S240 of FIG. 8 when the lock device 50 is in the unlocked state. Set to 0. When the permission flag Fa is set to 0 in S240 of FIG. 8, when it is determined that the flag F is 1 in S250 of FIG. 8, that is, when timer charging is being executed, charging is performed in S260 of FIG. It is determined whether or not the connector 410 is connected to the inlet 220, and if the state in which the charging connector 410 is connected to the inlet 220 continues until the timer T becomes equal to or higher than a predetermined value (when affirmatively determined in S270). , The permission flag Fa is set to 1 in S210. When the permission flag Fa is set to 1, the timer charging unit 310 makes a positive determination in S140 of FIG. 7 and executes external charging in S150. Further, when the permission flag Fa is set to 0, the timer charging unit 310 makes a negative determination in S140 of FIG. 7, and stops the external charging in S160.

As described above, the first control unit 320 sets the permission flag Fa to 1 when the lock device 50 is in the locked state to allow the execution of external charging, and when the lock device 50 is in the unlocked state. Set the permission flag Fa to 0 and stop external charging. Further, when the timer charging unit 310 is executing the timer charging (when the flag F is 1 in S250 of FIG. 8), the first control unit 320 unlocks the lock device 50 while the timer charging is being executed. When the charging connector 410 is connected to the inlet 220 from the time when the unlocked state is set to the time when the timer T reaches a predetermined value or more (for a predetermined period) (S260 → S270 (S260 → S270). → S280) → S210), the permission flag Fa is set to 1, the execution of external charging is permitted, and the external charging is restarted.

As described above, when the affirmative judgment is made in S270 of FIG. 8 and the permission flag Fa is set to 1 in S210, the external charging is executed again in S150 of FIG. 7 (external charging is restarted). Become. At this time, the lock device 50 may be changed from the unlocked state to the locked state. After the lock device 50 is in the unlocked state and external charging is stopped, when the external charging is restarted, the lock device 50 is shifted to the locked state, so that the charging connector 410 is not prepared from the inlet 220 during external charging. It can be prevented from coming off.

In the above embodiment, the charging start time for timer charging is set according to the flowchart shown in FIG. 6, but the charging schedule for timer charging may be set in any way. For example, the user can arbitrarily set the charging schedule, set the scheduled charging time from 22:00 to 3:00 on weekdays, and set the scheduled charging time from 0:00 to 6:00 on weekends (Saturday and Sunday). It may be anything. The timer charging unit 310 determines the charging power and the charging start time so that the SOC of the battery 100 can be charged to a predetermined value during the set scheduled charging time, and executes external charging. In this case, regardless of whether or not power is being supplied from the charger 200 to the battery 100, the first control unit 320 determines that timer charging is being executed during the scheduled charging time set by the user, and permits it. The flag Fa may be set.

In the above embodiment, the execution of the external charge is permitted or the external charge is stopped by setting the permission flag Fa, but if the external charge can be executed / stopped, it is controlled. Any aspect may be used. In the charge control device, external charging can be executed when the lock device 50 is in the locked state, external charging is stopped when the lock device 50 is in the unlocked state, and the lock device 50 is unlocked during timer charging. External charging is stopped when the state is reached, but if the charging connector 410 is connected to the inlet 220 for a predetermined period from the time when the unlocked state is reached, the execution of external charging is restarted. It suffices if it is configured.

The embodiments disclosed this time should be considered to be exemplary in all respects and not restrictive. The scope of the present invention is shown by the scope of claims rather than the description of the embodiment described above, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
