  Furthermore, a cargo compartment floor 22 is provided at the rear of the vehicle body (rear of the passenger compartment) of the vehicle 1 (part of which is shown in FIG. 1). A recess 24 is formed on the upper surface side of the cargo compartment floor 22. In this recess 24, an inverter 26 that converts a direct current supplied from the battery 16 into an alternating current of a commercial power supply voltage (for example, 100V), and a supply of the alternating current converted by the inverter 26 to the outside of the vehicle are controlled. A control box 28 as a control device is arranged. The power cable 30 connecting the inverter 26 and the junction box 10 is routed along the battery 16 along with the charging cable 20 on the lower surface side of the passenger compartment floor.

  Furthermore, with reference to FIG. 2, the detail of arrangement | positioning of the electrical component of an electric power feeding system is demonstrated. FIG. 2 is a plan view showing the cargo compartment floor of the vehicle on which the vehicle power supply system according to the embodiment of the present invention is mounted.

  FIG. 2 is a plan view showing the inverter 26 and the control box 28 disposed in the recess 24 of the cargo compartment floor 22. As shown in FIG. 2, a concave portion 24 having a substantially circular planar shape is formed on the upper surface side of the cargo compartment floor 22. As this recessed part 24, the spare tire pan provided in the luggage compartment floor 22 of the conventional vehicle can be diverted, for example. The inverter 26 and the control box 28 are arranged side by side in the vehicle width direction on the bottom surface 24 a of the recess 24.

  On the upper surface of the control box case 28a as the casing of the control box 28, there are an operation switch 28b for switching ON / OFF of power supply to the outside of the vehicle, and an outlet 28c which is a power supply terminal for outputting an alternating current output from the inverter. And are provided.

  A plug at one end of a connection cable 34 that is a connection means connection for connecting the outlet 28c and an external device is inserted into the outlet 28c in the vehicle. The outlet 28a is a standard outlet for commercial power. The connection cable is a standard product for commercial power supply, and may be, for example, a commercially available table tap or a plug cord of home appliances. The alternating current supplied from the inverter 26 is directly supplied from the outlet 28c to an external device such as a home appliance without going through an external facility such as a transformer, an inverter, or a frequency converter.

  Next, with reference to FIG. 3, an electrical configuration of a vehicle equipped with the vehicle power supply system according to the embodiment of the present invention will be described. FIG. 3 is a block diagram of the vehicle power supply system according to the embodiment of the present invention.

  As shown in FIG. 3, the junction box 10 is connected to the battery 16, the motor inverter 10, and the inverter 26, and switches the supply of direct current from the battery 16 to the motor inverter 10 and the inverter 26.

  The motor inverter 8 converts a direct current supplied from the battery 16 through the junction box 10 into an alternating current and supplies the alternating current to the motor unit 6. The driving force generated by the motor unit 6 is transmitted to the drive wheels 4 through a power transmission mechanism such as a transaxle.

  The battery charger 12 charges the battery 16 with the electric power supplied from the charging receptacle 18 via the charging cable 20. That is, the battery 16 is charged via the charging cable 20 and the battery charger 12 by connecting a charging plug provided at the tip of a charging cord drawn from an external power source such as a charging stand to the charging receptacle 18.

  The inverter 26 is connected to the junction box 10 via the power cable 30. The inverter 26 converts a direct current supplied from the battery 16 via the junction box 10 and the power cable 30 into an alternating current of a commercial power supply voltage (for example, 100 V), and outputs it to the control box 28 via the output cable 32. To do.

  The control box 28 is connected to the inverter 26 via the output cable 32 and controls the supply of the alternating current converted by the inverter 26 to the outside of the vehicle.

  Furthermore, the vehicle power supply system is controlled by a vehicle control module (VCM) 60 that controls various systems mounted on the vehicle 1. A signal indicating the setting state of the ignition 61 is input to the vehicle control module 60 from an ignition (IG) 61. When the ignition 61 is a cylinder type, the vehicle control module 60 may determine that the vehicle is in an inoperable state when the ignition 61 is set to ACC (accessory), or the ignition 61 is IG. When set to (ON, start), it may be determined that the vehicle is in an inoperable state. When the ignition 61 is a push start type, the vehicle control module 60 may determine that the vehicle cannot travel when the start button is pressed and the vehicle is ON.

  In addition, a signal indicating the set state of the range is input from the shift range 62 to the vehicle control module 60. The vehicle control module 60 may determine that the vehicle cannot travel when the shift lever is set to a parking (P) position, or when the parking button is pressed and It may be determined that the vehicle cannot travel. Furthermore, the vehicle control module 60 may determine that the vehicle is in an inoperable state only when the ignition 61 is set to the ON state and the shift range 62 is set to parking.

  The vehicle control module 60 receives a signal indicating an insulation resistance value between the power feeding system and the ground from the insulation resistance monitor 63. If the power feeding system is grounded, the insulation resistance value will decrease. The vehicle control module 60 may determine that leakage has occurred when the insulation resistance value is equal to or less than a predetermined value.

  In addition, the vehicle control module 60 displays desired information on the display device 64. The display device 64 may be arranged in the meter of the instrument panel in the vehicle compartment, or may be arranged in the control box 28.

Next, with reference to the flowchart of FIG. 4, the operation example of the vehicle electric power feeding system by embodiment of this invention is demonstrated.
A user who wants to supply power from the battery 16 of the vehicle 1 to an external device first performs an operation of switching the operation switch 28b provided in the control box 28 from OFF to ON (S401). The vehicle control module 60 may replace the operation of the operation switch 28b by detecting that the plug of the connection cable is connected to the outlet 28c of the control box 28. The attachment / detachment of the plug to / from the outlet 28c may be detected mechanically or electrically by providing an attachment / detachment sensor on the outlet 28c.

  Subsequently, the vehicle control module 60 determines whether or not the vehicle 1 is in an inoperable state (S402). Here, the vehicle control module 60 indicates that the vehicle control module 60 is in an inoperable state only when the ignition 61 is set to ON and the shift range 62 is set to parking. to decide. That is, the vehicle control module 60 determines that the vehicle is ready to run in at least one of the case where the ignition 61 of the vehicle is in the ON state and the case where the parking state of the shift range 62 is released, Even if the power supply request operation is executed, the non-power supply state is maintained.

When the vehicle control module 60 determines that the vehicle 1 is in a travelable state (in the case of “no” in S402), the reason why the ignition 61 is set to the ON state as the reason why power cannot be supplied to the display device 64, and Then, the fact that the shift range 62 is set to parking is displayed. For example, the display device 64 may display “Please turn off the IG key and set the range to P”. Based on the display, the user can perform the displayed operation necessary for supplying power.

  The vehicle control module 60 may determine that the vehicle 1 is in a travelable state when the setting of the ignition 61 is in the ON state. In that case, it is preferable to display “Please turn off the IG key” on the display device 64. In addition, the vehicle control module 60 may determine that the vehicle 1 is in a travelable state when the shift range 62 is released from parking. In that case, “Please set the range to P” may be displayed on the display device 64.

  Subsequently, the vehicle control module 60 maintains a non-power supply state in a travelable state. Thus, the vehicle control module 20 does not perform power supply from the power supply terminal when the vehicle is in a travelable state. For this reason, it is prevented that the vehicle 1 starts driving | running | working during the electric power feeding to an external device. Thus, it is possible to prevent the vehicle 1 from starting running during power feeding and disconnecting the connection cable connected to the vehicle 1 to suddenly stop the device outside the vehicle or dragging the device outside the vehicle to the vehicle 1. it can. Therefore, it is possible to prevent the vehicle 1 from traveling while power is being supplied to the external device and to achieve safe power supply.

  On the other hand, when the setting of the ignition 61 is OFF and the shift range 62 is set to parking (in the case of “yes” in S402), the vehicle control module 60 determines whether or not the vehicle 1 is being charged. Is determined (S403). Whether or not power is being received may be determined based on a signal input from the battery charger 12 to the vehicle control module 60, or may be determined as being charged when a charging outlet is connected to the charging receptacle 18. . The attachment / detachment state of the charging outlet to / from the charging receptacle 18 may be detected mechanically or electrically by providing an attachment / detachment sensor on the charging receptacle 18. The charging includes both rapid charging and normal charging.

When the vehicle control module 60 determines that the vehicle 1 is being charged (in the case of “yes” in S403), the vehicle control module 60 causes the display device 64 to display that charging is being performed as the reason why power cannot be supplied. For example, the display device 64 may display “Please unplug the charging plug”. Based on the display, the user can perform the displayed operation necessary for supplying power.

  Subsequently, the vehicle control module 60 maintains a non-power supply state (S407). By prohibiting power feeding during charging, it is possible to prevent a decrease in charging efficiency.

  On the other hand, when the vehicle 1 is not being charged (in the case of “no” in S403), the vehicle control module 60 confirms whether or not there is a leakage in the vehicle power supply system before starting the power supply from the outlet 28c that is the power supply terminal. (S404).

  When the vehicle control module 60 determines that there is a leakage (in the case of “no” in S404), the vehicle control module 60 displays a warning informing the leakage on the display device 64 (S501). Furthermore, it is preferable to display “Please consult with the dealer” on the display device 64.

  Subsequently, the vehicle control module stops all vehicle systems (S502). In the case where leakage is detected during power feeding, the power feeding system is first shut down and then the vehicle system is shut down. Furthermore, in order to prevent an electric shock, restart of the vehicle system is prohibited (S503).

  On the other hand, when there is no electric leakage (in the case of “yes” in S404), the vehicle control module 60 controls the control box 28 to start power supply from the outlet 28c (S405). The vehicle control module 60 may also permit power supply to in-vehicle devices other than the vehicle power supply system. Thereby, in-vehicle equipment can be used in the car, supplying power to equipment outside the car. For example, while supplying power, the user can listen to the radio in the car or operate the air conditioner.

  When the operation switch 28b provided in the control box 28 is switched from ON to OFF (in the case of “yes” in S406), the vehicle control module 60 controls the control box 28 to supply power from the outlet 28c. Stop (S407).

  In addition, when the ignition 60 setting is switched from OFF to ON during power feeding (in the case of “no” in S402), the vehicle control module 60 is in the process of feeding power to the display device 64 as a reason that it cannot start. Display that there is. For example, the display device 64 displays “Please turn off the power supply system”. Based on the display, the user can perform the displayed operation necessary for starting.

  Then, the vehicle control module 60 maintains power supply and prohibits starting until the operation switch 28b of the control box 28 is switched from ON to OFF (S406), thereby maintaining the inoperable state. As a result, the start of traveling of the vehicle being fed is prevented.

  In addition, when a charging operation is performed during power feeding (in the case of “yes” in S403), the vehicle control module 60 causes the display device to display that power feeding is being performed as a reason why charging is not possible. For example, the display device 64 displays “Please turn off the power supply system”. Based on the display, the user can perform the displayed operation necessary for starting charging.

  The vehicle control module 60 maintains power supply and prohibits charging until the operation switch 28b of the control box 28 is switched from ON to OFF (S406). This prevents the start of charging during power feeding.

  By the way, as described above, when the setting of the ignition 61 is in the ON state, that is, after the start request operation is performed to switch the ignition from OFF to ON, the operation switch 28b of the control box 28 is turned ON from OFF. When a power supply requesting operation such as switching to is performed, a display notifying that the vehicle is ready to travel, for example, a message “Please turn off IG” is displayed on the display device 64. On the other hand, if a start request operation for switching the ignition from OFF to ON is performed after a power supply request operation for switching the operation switch 28b of the control box 28 from OFF to ON is performed, power supply is performed. A display for notifying that the state is present, for example, a message “Please stop power supply” is displayed on the display device 64.

  The reason why different messages are displayed on the display device 64 in accordance with the order of operations in this way is that the last operation performed by the user is considered to be the current requested operation of the user. For this reason, information useful for realizing the last operation is displayed on the display device 64.

  Further, as described above, during charging, that is, after a charging request operation is performed such that a charging outlet is connected to the charging receptacle 18, a power supply request is made to switch the operation switch 28b of the control box 28 from OFF to ON. When the operation is performed, a message “Please unplug the charging plug” is displayed on the display device 64. On the other hand, when a charging request operation for connecting a charging outlet to the charging receptacle 18 is performed after a power feeding request operation for switching the operation switch 28b of the control box 28 from OFF to ON is performed. For example, a message “Please stop power supply” is displayed on the display device 64. This is also because information useful for realizing the last operation is displayed on the display device 64.

  Note that the driver who operates the ignition 60 at the driver's seat sees the message “Please turn off the power supply system” and performs an operation to turn off the power supply system. In the example shown in FIG. 3, the operation switch 28 b of the power feeding system is provided in the control box 28 disposed in the luggage compartment. For this reason, the driver has to move from the driver's seat in order to operate the operation switch 28b. Therefore, it is desirable to provide an operation switch for switching ON / OFF of the power feeding system, for example, on the instrument panel at a position where it can be operated from the driver's seat. Thereby, the driver can perform the ON / OFF operation of the power feeding system without moving from the driver's seat. For example, it is advantageous when the driver unplugs the connection cable from the power supply outlet 28c in the luggage compartment, but forgets to turn off the operation switch 28b of the power supply system and operates the ignition 60 at the driver's seat.

  Further, the vehicle control module 60 may invalidate the operation of the operation switch for switching ON / OFF of the power feeding system when all the opening / closing parts of the vehicle 1 are locked. Thereby, it can prevent that the glass of the vehicle 1 with which all the opening-and-closing parts are locked is broken, and electric power feeding operation is performed arbitrarily.

  In addition, when power is supplied to the electrical equipment brought into the passenger compartment from the power supply plug, it is considered that the danger is low even if the vehicle travels. For this reason, it is good to provide the switch which can supply electric power, even when it is a case where a vehicle is not a run impossible state. By providing such a switch, it is possible to supply power to the electrical equipment brought into the passenger compartment even when the vehicle is traveling.

  In the above-mentioned embodiment, although the example which comprised this invention on the specific conditions was demonstrated, this invention can perform a various change and combination, and is not limited to this. For example, in the above-described embodiment, an example of an electric vehicle has been described, but the present invention is not limited to an electric vehicle. The present invention can also be applied to a vehicle such as a hybrid vehicle.
