Hereinafter, the present invention will be described with reference to the embodiments shown in FIGS. 1 to 6.
FIG. 1A shows each part of an electric vehicle, for example, a PHEV vehicle (hereinafter referred to as a vehicle) capable of traveling in which EV traveling or series traveling occupies a large part.
Reference numeral 1 in FIG. 1A is a vehicle body, 3 is a vehicle compartment formed in the vehicle body 1, 5 is a power unit chamber formed in the front portion of the vehicle body 1, and 7 is an instrument panel provided in the vehicle compartment 3. , 9 indicate a charging / discharging port provided on the side of the vehicle body 1. By the way, 1x indicates a front wheel, 1y indicates a rear wheel, and 1z indicates a steering wheel.

For example, in the power unit chamber 5, a motor 11 that drives the front wheels 1x, an inverter 11a connected to the motor 11, and a generator 13x that generates electricity using a fuel-operated engine 13 as a drive source (corresponding to the power generation system of the present application). Etc. are stored. Further, a battery 17 capable of storing electricity is provided in the lower part of the vehicle body 1. Then, the electric power generated by the generator 13x is input to the battery 17, and the electric power from the battery 17 is output to the motor 11 via the inverter 11a.

The charging / discharging port 9 is a component that can be connected to a charging cable (not shown) or a power feeding cable 10a extending from a V2H device 10 installed in an external house α.
When a charging cable (not shown) is connected to the charging / discharging port 9, the battery 17 can be charged from an external charging facility (not shown). When the power supply cable 10a of the V2H device 10 is connected, the electric power stored in the battery 17 and the electric power generated by the generator 13x can be supplied to the house α.

The instrument panel 7 is provided with an outlet 7a that allows the electric power of the battery 17 and the generated electric power to be directly supplied to an electric device such as a home electric appliance.
That is, the charging / discharging port 9 and the outlet 7a constitute a connection portion capable of supplying power from the vehicle to the outside in the present application.
Further, the instrument panel 7 is provided with a binocular meter panel 19 as shown in FIG. 1 (b), for example. A display device 21 (corresponding to the display unit of the present application) is provided in a part of the meter panel 19, for example, in the central portion. The display device 21 includes a display surface 21a that can be visually recognized by a user such as a driver, a display circuit unit (not shown) that displays different images on the display surface 21a, and a switch unit that switches the display image for each switch operation (not shown). (Not shown) and so on.

The display device 21 integrates EV driving, hybrid driving (series), charging mode, power supply mode using only the battery 17, and power generation by the battery 17 and the generator 13x (from both the battery 17 and the generator 13x). (Power can be supplied) The power supply mode, etc. are displayed. Further, various modes displayed on the display device 21 can be selected by a touch sensor (not shown).

Further, by operating the switch of the switch unit, for example, an image showing the remaining amount of the battery 17 by using a part of the display surface 21a, an image showing the remaining amount of fuel required for operating the engine 13, or when only EV driving is performed. Images showing the cruising range and the cruising range when EV driving and power generation driving are integrated are displayed.
In addition, for example, on the lower side of the display surface 21a, there is a distance setting unit 23 for ensuring (setting) traveling for the minimum necessary distance such as a predetermined distance from the current position to a place where refueling can be performed, and a charging / discharging port. An upper limit setting unit 25 for setting an upper limit value of the amount of electric power supplied from the 9 or the outlet 7a to the outside, a rotation speed setting unit 27 for setting the engine rotation speed when the engine 13 generates electricity, and the like are provided. ing.

On the other hand, for example, in the vehicle interior 3, the current output power in the power supply mode from the vehicle to the outside is used, for example, by using a control device for controlling the battery 17 and integrated control of the vehicle shown in FIG. 1 (c). It is equipped with a control system 31 that displays the power supply available time that can be continuously supplied.
Explaining the control system 31, reference numeral 37 in FIG. 1C is a BMU that monitors and controls the battery 17, and reference numeral 39 is an ECU that integrally controls the vehicle.

Of these, the BMU (Battery Management Unit) 37 has a function of detecting the remaining amount of the battery 17 based on output information from various sensors of the battery 17, and is used from the current battery 17 in the power supply mode from the vehicle to the outside. It has a function to detect the amount. Incidentally, the BMU 37 is connected to the battery 17, the inverter 11a, the charging / discharging port 9, the outlet 7a, and the like.
The ECU (Electronic Control Unit) 39 (control unit) is external from EV driving, hybrid driving (series driving), charging mode, and battery 17 only, based on information from, for example, BMU 37 and information set by various setting units. It has a function to execute a power supply mode for supplying power to the outside and a power supply mode for supplying the output power from the battery 17 and the generated power of the generator 13x to the outside.

The ECU 39 is set with a function of obtaining the latest power consumption (average) usage amount in the power supply mode in which power is supplied from the vehicle to the outside.
Further, the ECU 39 is set with a function of calculating the feedable time that can be continuously supplied with the current output power in the same power supply mode. This power supply possible time is a distance value set by the distance setting unit 23, for example, based on the power supplied from the vehicle to the outside and the latest power consumption (average) so that the vehicle can travel a predetermined distance after the power supply mode is stopped. For example, the power consumption required for traveling from the current position to the place where refueling can be performed is obtained, and the time obtained by subtracting the time corresponding to the same power consumption from the total power supply available time is used. Incidentally, as the current upper limit value of the output power, the value set by the upper limit setting unit 25 is used.

Further, the ECU 39 is set with a function of displaying the power supply available time that can be continuously supplied with the obtained current output power on the display surface 21a of the display device 21 as shown in FIG. 2A, for example. Here, the power supply time is "Time" together with the "outside output amount" (outside output power) of the electric power supplied to the outside and the "vehicle use amount" (vehicle use power) of the electric power used by the vehicle itself. It is designed to be digitally displayed as "to Empty". Incidentally, FIG. 2A shows an example of display when, for example, only the electric power of the battery 17 is permitted to be supplied to the outside.

Further, when the supply of electric power from the battery 17 to the outside and the supply of the electric power generated by the engine operation to the outside are permitted on the display surface 21a, the display surface 21a is individually attached to the display surface 21a, that is, the battery, for example, as shown in FIG. 2B. The power supply available time that can be continuously supplied to the outside by the electric power of 17 and the power supply available time that can be continuously supplied to the outside by the electric power generated by the engine operation are displayed respectively.

In this case, the power supply available time by operating the engine is displayed as the time remaining for the time corresponding to the power consumption required for traveling a predetermined distance. Incidentally, the engine 13 at this time is operated at the rotation value set by the rotation speed setting unit 27.
Further, the ECU 39 displays an alert in the power supply mode, for example, when the time when the power supply from the vehicle to the outside is stopped is approaching, a warning notifying that the power supply stop is near before the stop time, for example. A function is set to display an alert to the effect that "power supply is stopped after one hour" on the display surface 21a as shown in FIG.

In addition, when the power consumption of the external device fluctuates significantly, that is, more than a predetermined value in the middle of the power supply mode, the ECU 39 causes the entire display surface 21a as shown in FIG. 4, for example, to blink, resulting in a large power consumption. A notification function is also set to notify that the power has changed.
Further, the ECU 39 can communicate with a mobile terminal with a display screen, for example, a smartphone 43 via a communication device 41 (for example, Bluetooth (registered trademark)), and the power supply available time displayed on the display surface 21a, an alert, and the like. The fluctuation of the power consumption is also displayed on the display screen (not shown) of the smartphone 43.

Of course, as shown by the alternate long and short dash line in FIG. 1 (c), the above information may be displayed on the smartphone 43 via Internet communication or a cloud 42 (external storage device).
Next, the operation will be described with reference to FIGS. 1 to 4.
For example, it is assumed that when the supply of electric power in the city is stopped due to a disaster or the like and a power outage occurs in the house α, the electric power of the vehicle is used as a response.

At this time, the user parks the vehicle near the V2H device 10 of the house α, and connects the power supply cable 10a extending from the V2H device 10 to the charging / discharging port 9 of the vehicle.
Then, the user selects from the display surface 21a of the display device 21 an external output only by the electric power of the battery 17 or an external output that integrates the electric power of the battery 17 and the electric power generated by the engine operation, and supplies the electric power to the outside. Execute power supply mode.

At this time, the user sets a required distance (predetermined distance) from the distance setting unit 23 assuming refueling of the vehicle, or sets an upper limit value of the amount of electric energy supplied from the upper limit setting unit 25 to the outside. , The engine speed is set from the rotation speed setting unit 27 in order to perform low noise and high efficiency operation of the engine operation. By the way, these set values may be unique values.
Here, a case where only the electric power of the battery 17 is supplied to the outside will be described as an example.

In this case, as shown in FIG. 1A, the electric power of the battery 17 is supplied from the vehicle to the distribution board 51 of the house α via the power supply cable 10a and the V2H device 10. As a result, various electric devices such as home appliances such as lighting of the house α are used.
In this power supply mode, by operating the display device 21, the power supply available time that can be continuously supplied with the current output power as shown in FIG. 2A is digitally displayed on the display surface 21a as "Time to Empty". To. By the way, the power supply time is based on the current battery capacity, the latest usage amount (average), the set upper limit of the output power, the set predetermined distance, and the like.

Since the power supply available time at this time is displayed together with the "outside output amount" supplied to the outside and the "vehicle usage amount" used by the vehicle, the current output status is easy to understand.
When the power of the battery 17 and the generated power are permitted, as shown in FIG. 2B, the power supply available time that can be continuously supplied to the outside by the power from the battery 17 and the power generated by the engine 13 continue to the outside. And the power supply available time that can be supplied is displayed respectively. At this time, the power supply possible time is a time considering the distance value input from the distance setting unit 23.

Of course, the above information is also displayed on the display screen (not shown) of the smartphone 43.
As the power supply to the house α progresses, the power supply available time decreases.
At this time, if the power outage of the house α is prolonged and you want to extend the power supply time, you can change the upper limit of the current output power based on the displayed outside output amount and power supply time, or you are currently using it. Change how to use home appliances.

When supplying the generated power of the generator 13x by the engine operation to the outside, it is considered to lower the engine speed set for low noise and high efficiency operation.
Further, when the available power supply time decreases, for example, one hour (predetermined time) before the time when the power supply from the vehicle to the outside is stopped, the power supply stop is close to the display surface 21a as shown in FIG. A warning display is displayed to inform that, for example, an alert stating that "power supply will be stopped after 1 hour" is displayed. The recognition of this display gives the user an opportunity to devise ways to change the way home appliances are used.

By taking such measures, the time available for power supply can be extended as much as possible.
On the other hand, when the power consumption of the external device fluctuates significantly, that is, more than a predetermined value in the power supply mode of the vehicle, the entire display surface 21a blinks as shown in FIG. 4, and the power consumption is significantly reduced. Notify that it has changed.
At this time, the user recognizes that a situation has occurred in which the power supply time is suddenly reduced, and reviews the usage of the home electric appliance or changes the setting in the same manner as described above. As a result, the sharp decrease in the power supply time can be suppressed, and the use with a large power consumption can be suppressed.

When the power supply available time displayed on the display surface 21a reaches zero time, the power supply from the vehicle to the outside is stopped.
At this time, the vehicle is in a state where it can run as much as it can be charged and refueled. Therefore, the vehicle can supply power to the house α again when it returns to the house α after traveling to the charging station or the refueling station with the remaining runnable power and fuel to charge and refuel.

As a result, the limited electric power provided by the vehicle is effectively used in the house α. Of course, the same applies when a home electric appliance is connected to the outlet 7a of the vehicle.
Therefore, as in the present embodiment, the user can easily set the power supply possible time when the power supply is continued with the current power consumption amount only by visually observing the power supply possible time displayed on the display surface 21a of the display device 21. It is possible to grasp and easily change the usage of the electric equipment currently used, and to make it possible to devise such as how long the power supply time can be extended, and the power supply power of the limited vehicle can be effectively used. It is effective in cases such as disasters where power outages last for a long time.

In particular, by displaying the display on the smartphone 43 (portable terminal device), the user can easily know the change in the power supply possible time regardless of where the user is, that is, where the user is located.
Moreover, since the displayed power supply possible time is the time left for the time corresponding to the power consumption that the vehicle can travel over a predetermined distance, even if the power supply possible time becomes zero time, the power supply to the outside is stopped. However, the vehicle can be charged and refueled by traveling to a station where it can be charged and refueled, and the ability to supply external power can be secured again.

Further, since the predetermined distance can be set by the user by the distance setting unit 23, various situations can be easily dealt with.
Regarding the predetermined distance, in addition to the distance arbitrarily set by the user as described above and the preset distance, the power supply possible time becomes zero, such as the distance set by the user + α. However, it may be appropriately set within a range in which the state in which the vehicle can travel a predetermined distance or more is maintained.

Further, since the output power is displayed on the display device 21 or the like together with the available power supply time, the user can easily grasp the current output power and use it as a guide when adjusting the use of the electric device being used. It can be used.
Further, when the supply to the outside from the battery 17 and the supply of the generated power of the generator 13x by the engine operation (power generation system) to the outside are permitted, the display device 21 can continuously supply the power of the battery 17. Since the power supply available time and the power supply available time that can be continuously supplied by the engine operation are displayed, the user can easily grasp the current individual power supply status.

In addition, since the alert of the supply stop was displayed before the power supply from the vehicle to the outside was stopped, the opportunity to change the usage of home appliances was given, and the device to extend the power supply time as much as possible before the power supply was stopped. It can be performed.
In addition, by setting the upper limit of the power to be supplied and setting the engine rotation speed when generating power by engine operation (power generation system), the power supply time can be lengthened and the engine noise can be reduced to low noise. It is possible to suppress or operate the engine 13 with high efficiency.

In addition, by notifying that the power consumption has fluctuated more than a predetermined value in the power supply mode, it is possible to grasp that the power supply available time has decreased sharply, and it is easy to suppress the sudden decrease in power consumption during the power supply available time. By doing so, it is possible to suppress a large change in the power supply available time.
Further, in the above embodiment, two types of power supply modes can be selected: power supply from the battery 17 and power supply from both the generator 13x and the battery 17 driven by the engine 13, but these two types are available. The user may be able to select either the power supply mode of the above or the power supply mode in which only the power generated by the generator 13x is supplied to the outside without supplying the power from the battery 17 to the outside.

As described above, in the display device 21 or the like when three types of power supply modes can be selected: power supply from only the battery 17, power supply from only the generator 13x, and power supply from both the battery and the generator 13x. As the display pattern of the power supply possible time, for example, there are the patterns 1) to 7) described below. FIG. 5 is a power supply mode by the battery 17, and FIG. 6 is a display example of the power supply mode and the power supply possible time in the power supply mode by the battery 17 and the generator 13x.
1) When the power supply mode by either the battery 17 or the generator 13x is selected, the power supply available time in the selected power supply mode is independently displayed (for example, FIG. 5A).
2) When the power supply mode by either the battery 17 or the generator 13x is selected, the power supply available time in the selected power supply mode and the power supply available time in the power supply mode in which power is supplied from both the battery 17 and the generator 13x. Are displayed respectively (for example, FIG. 5B).
3) When the power supply mode using both the battery 17 and the generator 13x is selected, the power supply available time in the selected power supply mode is independently displayed (for example, FIG. 6A).
4) When the power supply mode by both the battery 17 and the generator 13x is selected, the power supply possible time in the power supply mode by the battery 17 and the power supply available time in the power supply mode by the generator 13x are displayed (for example, FIG. 6B).
5) When the power supply mode by both the battery 17 and the generator 13x is selected, the power supply possible time in the power supply mode, the power supply possible time in the power supply mode by the battery 17, and the power supply possible time in the power supply mode by the generator 13x are 3. The two power supply possible times are displayed (for example, FIG. 6C).
6) When the power supply mode by both the battery 17 and the generator 13x is selected, for example, when the power consumption is relatively small and the power is currently supplied from either the battery 17 or the generator 13x. Displays the power supply available time in the state where power is currently being supplied and the power supply available time by both the battery 17 and the generator 13x (for example, FIG. 6D, when power is supplied from the battery 17).
7) When the power supply mode by both the battery 17 and the generator 13x is selected, in the vehicle in which the power supply from the battery 17 is prioritized, the power supply possible time by the battery 17 and the power supply possible time by both the battery 17 and the generator 13x are set. Display (eg, FIG. 6D).

In this way, by appropriately setting the display of the power supply available time, the power supply available time can be appropriately grasped, and the electric vehicle having excellent usability can be obtained.
