Description

  The present invention relates to a battery state display device that displays a state of a driving battery mounted on an electric vehicle that uses electricity as at least a part of a driving source by display means.

  Conventionally, when charging an electric vehicle, there is known a charging system that displays a ratio of renewable power out of charging power on a liquid crystal monitor provided in a charger or prints on a receipt (for example, Patent Document 1). Thereby, the user visually recognizes the degree of contribution to the environment of the power consumed by the user.

JP 2010-220352 A

By the way, in the conventional charging system, the ratio of the renewable power out of the charging power is only displayed on a liquid crystal monitor or a receipt provided in the charger. On the other hand, when charging an electric vehicle, it is rare for a user to stare at a liquid crystal monitor of the charger and wait for a shopping or a coffee shop away from the charger. In addition, when charging at home, timer charging is often used to use nighttime electricity with low electricity charges, and the LCD monitor of the charger is not taken care of, and receipts can be issued when charging at home. It will be troublesome.
Therefore, even when charging is performed by selectively using renewable power, it is difficult for the user to fully grasp the fact, and it is difficult to recognize the degree of contribution of the power consumed by the user to the environment.

  The present invention has been made paying attention to the above problem, and allows the user to recognize that renewable power is being used, and can contribute to actively and selectively using renewable power. An object is to provide a display device.

In order to achieve the above object, the battery status display device of the present invention includes display means and display control means.
The display means displays a state of a driving battery mounted on an electric vehicle using electricity as at least a part of a driving source.
The display control means displays the display form of the display means when the renewable power generated without discharging carbon dioxide is charged, and the display of the display means when the renewable power is not charged at all. Different for the form.

In the battery status display device of the present invention, the display form of the display means when charging the renewable power generated without discharging carbon dioxide is the display of the display means when the renewable power is not charged at all. Different for form.
Here, the display means displays the state of the driving battery mounted on the electric vehicle using electricity as at least a part of the driving source. That is, since this display means displays important matters in the electric vehicle, it is more frequently watched by the user than the charger.
That is, by displaying the fact that the renewable power is used by using a display unit that is frequently watched by the user or the like, it is possible to cause the user to recognize that the renewable power is being used at a high frequency. As a result, it is possible to contribute to actively and continuously selecting and using renewable power.

[Configuration of battery status display processing]
FIG. 3 is a flowchart illustrating a flow of a battery state display process executed by the battery state display device according to the first embodiment. Hereafter, each step of the flowchart of FIG. 3 which shows the battery status display process content is demonstrated.

In step S1, it is determined whether charging from the charging apparatus 100 has been started. If YES (start charging), the process proceeds to step S2. If NO (charge stop), step S1 is repeated.
Here, the determination of the start of charging is performed based on whether there is power supply from the charging device 100, that is, whether a charging signal is input from the charging lamp 12.

In step S <b> 2, following the determination that charging is started in step S <b> 1, it is determined whether or not renewable power is included in the power supplied from the charging device 100. If YES (with renewable power), the process proceeds to step S4. If NO (no renewable power), the process proceeds to step S3.
Here, the determination of whether or not renewable power is included is made based on a signal (power information) indicating the origin of power output from the charging apparatus 100.

In step S3, following the determination that there is no regenerative power in step S2, default display processing is executed assuming that no rechargeable power is charged, and the process proceeds to the end.
Here, the “default display process” is a default display process executed when no chargeable power is charged, that is, when only environmental load power is charged.
For example, in the power-off state, the battery meter 21f is not displayed on the combination meter 21, and only the charging lamp 12 is lit. Then, when the power is turned on, the startup sound of the in-vehicle buzzer 30 is set to a preset default sound and is activated. The default sound is, for example, a series of high-pitched single sounds. The display form of the battery fuel gauge 21f of the combination meter 21 is set to a preset default form and displayed. In this default form, for example, the number of segments 21h corresponding to the ratio of the remaining battery capacity to the total capacity is lit, and the inner segment 21j adjacent to the inside of the lit segment is displayed in the same display color / The display is lit with display color saturation, display color brightness, and display pattern. At this time, the display on the outside display 22 and the mobile terminal display 23 is not performed.

In step S4, following the determination that there is renewable power in step S2, it is determined whether or not the electric vehicle 10 is powered on, assuming that the renewable power is charged. If YES (power on), the process proceeds to step S5. If NO (power off), the process proceeds to step S6.
Here, the power ON / OFF determination is made based on the ON / OFF signal from the power switch 13.

  In step S5, following the determination that the power is turned on in step S4, a startup control process is executed, and the process proceeds to step S7. This startup control process will be described later.

In step S6, following the determination that the power is turned off in step S4, it is determined whether one or more passengers are in the passenger compartment. If YES (there is an occupant), the process proceeds to step S8. If NO (no occupant), the process proceeds to step S10, and the battery charge amount is not displayed on the combination meter 21.
Here, the presence or absence of an occupant is determined based on an occupant signal from the occupant sensor 14.

In step S7, following execution of the startup control process in step S5, it is determined whether or not the vehicle speed of the electric vehicle 10 is zero. If YES (zero vehicle speed), the process proceeds to step S8. If NO (greater than the vehicle speed), the process proceeds to step S9.
Here, the vehicle speed is determined based on the speed signal from the speed sensor 15.

  In step S8, following the determination that there is no occupant in step S6 or the determination that the vehicle speed is zero in step S7, display form control processing is executed, and the process proceeds to step S10. This display form control process will be described later.

In step S9, following the determination that the vehicle speed is not zero (greater than zero) in step S7, the display form of the battery fuel gauge 21f of the combination meter 21 is set in advance, assuming that the electric vehicle 10 is running. The default form is set and displayed, and the process proceeds to step S10.
At this time, the battery remaining amount display unit is not displayed on the outside display 22 and the mobile terminal display 23.

In step S10, following the execution of step S8 or the display in the default form of step S9, it is determined whether or not the charging from the charging apparatus 100 has ended. If YES (end of charging), the process proceeds to step S11. If NO (continuation of charging), the process returns to step S4.
Here, the determination of the end of charging is performed based on whether or not the power supply from the charging device 100 is stopped, that is, whether or not the input of the charging signal from the charging lamp 12 is stopped.

In step S11, it is determined whether or not the power source of the electric vehicle 10 is in an off state following the determination that charging is ended in step S10. If YES (power off), the process proceeds to step S12. If NO (power on), the process proceeds to step S13.
Here, the power ON / OFF determination is made based on the ON / OFF signal from the power switch 13.

  In step S12, following the determination that the power is turned off in step S11, the remaining battery level indicator 21f, the remaining battery capacity display unit 22a, and the like are displayed on each of the combination meter 21, the outside display 22, and the mobile terminal display 23. If it is, the display is turned off and the process proceeds to step S14.

In step S13, following the determination that the power is turned on in step S11, the display form of the battery fuel gauge 21f of the combination meter 21 is set to a preset default form, assuming that the electric vehicle 10 is maintained in a travelable state. Set and display, then proceed to step S14.
At this time, no display is performed on the outside display 22 and the mobile terminal display 23.

  In step S14, following the display turn-off in step S12 or the display in the default form in step S13, the communication timing of the communication device 26 with an external device such as the charging device 100 is detected, and the process proceeds to step S15.

  In step S15, following the detection of the communication timing in step S14, information on the fact that the renewable power is charged and the amount of charge of the renewable power is output to the communication device 26. As a result, the fact that the renewable power is charged to the external device and the information on the charge amount of the renewable power within the charge amount at the end of the charge is transmitted via the communication device 26, and the process proceeds to the end.

[Configuration of startup control processing]
FIG. 4 is a flowchart illustrating a flow of start-up control processing executed by the battery state display device according to the first embodiment. Hereinafter, each step of the flowchart of FIG. 4 showing the contents of the startup control process will be described.

In step S51, it is determined whether or not the number of continuous charges of renewable power is less than a predetermined threshold number. If YES (less than the threshold number), the process proceeds to step S52. If NO (more than the threshold number), the process proceeds to step S53.
Here, the display controller 24 counts the number of rechargeable power charges. Further, the threshold number can be arbitrarily set.

  In step S52, following the determination that the charging frequency is less than the threshold value in step S51, the startup sound of the in-vehicle buzzer 30 is set to a sound A that is different from the preset default sound, and the process proceeds to step S54. Note that the sound A is, for example, a series of high-pitched long tones twice.

  In step S53, following the determination that the number of times of charging is equal to or greater than the threshold value in step S51, the startup sound of the in-vehicle buzzer 30 is set to a preset default sound and a sound B different from the sound A, and the process proceeds to step S54. Note that the sound B is, for example, a continuous long low tone twice.

  In step S54, following the setting of the start-up sound in step S52 or step S53, the start-up sound in which the in-vehicle buzzer 30 is set is sounded and the process proceeds to the end.

[Configuration of display form control processing in combination meter]
FIG. 5 is a flowchart illustrating the flow of the display mode control process in the combination meter executed by the battery state display device according to the first embodiment. Hereafter, each step of the flowchart of FIG. 5 which shows the display form control processing content in a combination meter is demonstrated.

  Here, the display mode control process executed in step S8 in the battery state display process shown in FIG. 3 is different between the process performed on the combination meter 21 and the process performed on the outside display 22. . Therefore, this display form control process is divided into a display form control process in the combination meter and a display form control process in the outside display, and will be described respectively. In addition, since the process performed with respect to the mobile terminal display 23 is the same as the process performed with respect to the display 22 outside a vehicle, description is abbreviate | omitted here.

In step S801, it is determined whether the number of continuous charges of renewable power is less than a predetermined threshold number. If YES (less than the threshold number), the process proceeds to step S802. If NO (more than the threshold number), the process proceeds to step S803.
Here, the display controller 24 counts the number of rechargeable power charges. Further, the threshold number can be arbitrarily set.

  In step S802, following the determination that the charge count is less than the threshold value in step S801, the display form of the battery fuel gauge 21f of the combination meter 21 is set to form A different from the preset default form. That is, among the inner segments 21j in the battery fuel gauge 21f, the display form of the inner segment 21j adjacent to the inside of the segment 21h indicating the ratio corresponding to the charged renewable power is set to form A, and the process proceeds to step S804. Transition.

As shown in FIG. 6A, this form A is different from the default form in that any one of the display color, the saturation of the display color, the brightness of the display color, and the display pattern is made different. is there. In FIG. 6A, the setting indicated by “◯” is a setting different from the default form, and the setting indicated by “−” is the same setting as the default form.
Here, which of Pattern 1 to Pattern 4 is selected depends on the basic design specifications of the electric vehicle 10. The reason for this basic design specification is that the colors that can be used in the combination meter 21 or the number of colors that can be used are determined by laws and regulations, internal regulations, the meaning of colors varies depending on the culture, the remaining battery power This is because there are various cases such as not using colors in the first place.
In addition, the brightness is often determined to be within a tolerance of ± 20% within the range of “shining” in the design specifications. It may be difficult to give a “different from the default form” recognition by making all the brightness of the lit inner segment 21j different from the default form. However, since the brightness of the inner segment 21j adjacent to the inside of the segment 21h indicating the ratio corresponding to the charged renewable power in the battery 11 is made different, it is adjacent to the inside of the segment 21h indicating the ratio corresponding to the environmental load power. Adjacent to the inner segment 21j. For this reason, even if the tolerance is within a range of ± 20%, it can be recognized as “different from the default form”.
In general, the brighter and brighter images are more “good” and “clean”. Therefore, when making the brightness different, it is preferable to set the brightness higher than the default form.

In step S803, the display form of the battery fuel gauge 21f of the combination meter 21 in step S801 is set to a preset default form and form B different from form A. That is, among the inner segments 21j in the battery fuel gauge 21f, the display form of the inner segment 21j adjacent to the inner side of the segment 21h indicating the ratio corresponding to the charged renewable power is set to the form B, and the process goes to step S804 Transition.
In the form B, as shown in FIG. 6B, when the display color is changed from the default form in the form A, the display color is further changed (pattern 1-1), or the display color is changed. In addition to the above change, the saturation of the display color is changed (pattern 1-2), the saturation of the display color is changed (pattern 1-3), and the display pattern is changed (pattern 1-4). Further, when the saturation of the display color is changed from the default form in the form A, the saturation is further changed (pattern 2-1) or the display color is changed in addition to the change of the saturation of the display color. (Pattern 2-2), the brightness of the display color is changed (pattern 2-3), and the display pattern is changed (pattern 2-4). The same applies to the case where the luminance of the display color is different from the default form in the form A and the case where the display pattern is made different from the default form in the form A.
In FIG. 6B, the setting indicated by “△” is a setting different from the default form and form A, the setting indicated by “◯” is a setting different from the default form, and indicated by “−”. Is the same setting as the default mode.
Here, which of Pattern 1-1 to Pattern 4-4 is selected depends on the basic design specifications of the electric vehicle 10.

  In step S804, following the setting of the display form in step S802 or step S803, the remaining battery level indicator 21f of the combination meter 21 is displayed in the set display form, and the process proceeds to the end. Thereby, the display form of the inner segment 21j adjacent to the inner side of the segment 21h indicating the ratio corresponding to the charged renewable power among the inner segments 21j in the battery fuel gauge 21f is different from the default form. Of the inner segment 21j in the battery fuel gauge 21f, the inner segment 21j adjacent to the inner side of the segment 21h indicating the ratio corresponding to the charged environmental load power is displayed in a default form.

[Configuration of display form control processing on the outside display]
FIG. 7 is a flowchart illustrating a flow of a display form control process on a display outside the vehicle that is executed by the battery state display device according to the first embodiment. Hereafter, each step of the flowchart of FIG. 7 which shows the display type control processing content in a display outside a vehicle is demonstrated.

In step S811, it is determined whether or not the user permits display of the remaining battery level on the outside display 22. If YES (display permission), the process proceeds to step S812. In the case of NO (prohibited display), the process proceeds to the end, and no special display relating to renewable power is performed on the outside display 22. That is, the battery remaining amount display unit 22a is turned off.
Here, the display permission is determined based on the permission signal or the prohibition signal output from the permission switch 16.

In step S812, following the determination that display is permitted in step S811, the display form of the battery remaining amount display portion 22a of the outside display 22 is set to a form A ′ different from the preset default form, and the process proceeds to step S813. Transition.
Here, the battery remaining amount display unit 22a of the vehicle outside display 22 is off by default, so that the form A ′ is the display color, the saturation of the display color, the luminance of the display color, and the display of the remaining battery amount display unit 22a. The pattern pattern is set to a predetermined setting.

  In step S813, following the setting of the display form in step S812, the battery remaining amount display unit 22a of the outside display 22 is displayed in the set display form, and the process proceeds to the end.

[Configuration of battery status display processing during power consumption]
FIG. 8 is a flowchart illustrating a flow of a battery state display process at the time of power consumption executed by the battery state display device according to the first embodiment. Hereafter, each step of the flowchart of FIG. 8 which shows the battery state display processing content at the time of power consumption is demonstrated.

In step S100, it is determined whether power is consumed in the battery 11 of the electric vehicle 10 or not. If YES (with power consumption), the process proceeds to step S101. If NO (no power consumption), step S100 is repeated.
Here, the presence or absence of power consumption is determined based on whether or not the battery 11 is discharged.

In step S101, following the determination that power is consumed in step S100, it is determined whether or not the battery 11 is charging both renewable power and environmental load power. If YES (both charging), the process proceeds to step S102. If NO (only one of them is charged), the process proceeds to step S103.
Here, the type of charging power is determined based on a signal (power information) indicating the origin of power input from the charging device 100.

In step S102, following the determination of charging both the renewable power and the environmental load power in step S101, the segments 21h of the battery fuel gauge 21f are turned off sequentially from the top in accordance with the amount of power consumed in the battery 11. Move to the end. At this time, the inner segment 21j adjacent to the extinguished segment 21h is also extinguished, but the inner segment 21j indicating the charging amount of environmental load power is extinguished earlier than the inner segment 21j indicating the charging amount of renewable power. .
That is, in the plurality of inner segments 21j arranged in the vertical direction, the remaining battery level corresponding to the charge amount of renewable power is displayed on the lower side, and the remaining battery level corresponding to the charge amount of environmental load power is displayed on the upper side. .

  In step S103, following the determination that only one of the renewable power and the environmental load power is charged in step S101, the segment 21h of the battery fuel gauge 21f is sequentially arranged from the upper side in accordance with the amount of power consumed in the battery 11. Turns off and moves to end. At this time, the inner segment 21j adjacent to the extinguished segment 21h is also extinguished sequentially from the upper side.

Next, the operation will be described.
First, “importance of the recognition of the use of renewable power” will be described, and then the actions in the battery status display device of the first embodiment will be described as “in-vehicle display action during charging of renewable power”, “when charging renewable power” The description will be divided into “outside vehicle display operation” and “power-on operation during charging of renewable power”.

[Importance of using renewable power]
Renewable power, which is generated by using solar power and wind power without emitting carbon dioxide, has high attention and expectation for environmental conservation, but for the time being, power generation costs are cheaper than fossil fuels. Less likely.
Renewable power, which has the same quality and characteristics as environmental load power, but becomes expensive due to the cost of power generation, is not only temporary interest to consumers, but also actively and continuously In order to have them selectively used, it is necessary to obtain benefits other than the financial benefits of renewable power.

  On the other hand, when charging an electric vehicle, the proportion of renewable power out of the charged power is displayed on a liquid crystal monitor provided in the charger or printed on a receipt to use the renewable power. Recognize that This recognition becomes “praise” for users who use renewable power, and it is a merit other than the financial merit of renewable power.

However, with the LCD monitor and receipt printed on the charger, it is difficult for the user to recognize the fact that renewable power is used. The effect could not be demonstrated.
That is, “praise” for using renewable power is surely communicated to the user. Furthermore, an indirect “praise” for the user is also generated by informing the person other than the user that the renewable power has been used. For these reasons, it is necessary to increase the number of “praises” and to ensure that the number of “praises” is transmitted, and to contribute to making consumers actively and continuously select and use renewable power.

[In-vehicle display when charging renewable power]
FIG. 9 is a diagram showing display by the battery fuel gauge of the first embodiment, where (a) shows the form A, (b) shows the form B, and (c) shows the default form.
A description will be given of the in-vehicle display operation when charging the renewable power when the occupant is in the passenger compartment when the electric vehicle 10 is powered off and the charging device 100 is supplied with power including the renewable power.

  At this time, in the flowchart shown in FIG. 3, the process proceeds from step S1, step S2, step S4, step S6, and step S8. Here, when it is determined that charging is started in step S <b> 1, the charging lamp 12 disposed in the passenger compartment of the electric vehicle 10 is lit.

  When the display mode control process is executed in step S8, the process proceeds to step S801 in the flowchart shown in FIG. 5, and it is determined whether or not the regenerative power continuous charge count is less than the threshold count. If it is less than the threshold number, the process proceeds to step S802, and the display form of the inner segment 21j in the battery fuel gauge 21f of the combination meter 21 is set to form A different from the default form. And it progresses to step S804 and the display form of the battery fuel gauge 21f is displayed with the form A (refer Fig.9 (a)). That is, of the inner segment 21j in the battery fuel gauge 21f, the inner segment 21j adjacent to the inner side of the segment 21h indicating the ratio corresponding to the charged renewable power has a display color different from, for example, the adjacent segment 21h. Become.

  On the other hand, when power that does not include any renewable power is supplied from the charging device 100, when only environmental load power is charged, the process proceeds from step S1 to step S2 to step S3 in the flowchart shown in FIG. . For this reason, the display form of the battery fuel gauge 21f of the combination meter 21 is set to the default form. As a result, the inner segment 21j in the battery fuel gauge 21f has the same display color regardless of whether or not it is adjacent to the inner side of the segment 21h indicating the ratio corresponding to the charged renewable power (FIG. 9 ( c)).

  Thus, the display form of the battery fuel gauge 21f of the combination meter 21 is when the regenerative power is charged (set to form A) and when the regenerative power is not charged at all (set to the default form). ) And different. Here, since the battery fuel gauge 21 f displays important matters in the electric vehicle 10, the frequency of visual confirmation by an occupant such as a user is higher than that of the charging device 100. Therefore, the fact that the renewable power is selectively used can be transmitted to the user or the like at a high frequency, and “praise” for the selective use of the renewable power is reliably transmitted to the user. As a result, the user can recognize the degree of contribution to the environment of the power consumed by the user and contribute to actively and continuously selecting and using renewable power.

  If it is determined in step S801 of the flowchart shown in FIG. 5 that the number of continuous regenerative power chargings is equal to or greater than the threshold number, the process proceeds to step S803, and the display form of the inner segment 21j in the battery fuel gauge 21f of the combination meter 21 is displayed. Is set to a default form and a form B different from the form A. And it progresses to step S804 and the display form of the battery fuel gauge 21f is displayed with the form B (refer FIG.9 (b)). That is, of the inner segment 21j in the battery fuel gauge 21f, the inner segment 21j adjacent to the inner side of the segment 21h indicating the ratio corresponding to the charged renewable power has a display color different from the adjacent segment 21h, for example. It becomes different brightness.

  Thus, when the regenerative power continuous charge count is equal to or greater than the threshold count, the battery fuel gauge 21f of the combination meter 21 is not charging any renewable power (set to the default form), and the reproducible power. Displayed in a different display form (form B) than when the number of continuous charges is less than the threshold number (set to form A). As a result, the fact that the user continues to selectively use renewable power can be communicated to the user at a high frequency, and further “praise” for the selective use of more renewable power can be assured to the user. It is transmitted.

  In particular, in the battery state display device 20 of the first embodiment, the segment (indicated by 21hα in FIG. 9A) of the inner segment 21j in the battery fuel gauge 21f that indicates the ratio corresponding to the charged renewable power. The display form of the inner segment adjacent to the inner side (indicated by 21jα in FIG. 9) is the inner segment adjacent to the inner side of the segment (indicated by 21hβ in FIG. 9A) indicating the ratio corresponding to the environmental load power (in FIG. 9). This is different from the display mode (shown by 21jβ in (a)). Therefore, the user can easily grasp the charge amount of the renewable power, and the user can recognize the degree of contribution to the environment of the power consumed by the user.

  On the other hand, when the electric vehicle 10 travels and power in the battery 11 is consumed, the process proceeds from step S100 to step S101 in the flowchart shown in FIG. When both the renewable power and the environmental load power are charged, the process proceeds to step S102, and the segment 21h of the battery fuel gauge 21f is turned off sequentially from the upper side according to the power consumption. When the inner segment 21j adjacent to the segment 21h is also turned off, the inner segment (in FIG. 9, the charging amount of the environmental load power) is larger than the inner segment (indicated by 21jα in FIG. 9) indicating the charging amount of the renewable power. 21jβ) is turned off first.

  Thereby, until the battery remaining amount becomes zero, the fact that the regenerative power is selectively used and manually charged can be continuously displayed on the battery remaining amount meter 21f. For this reason, the “praise” for the selective use of the renewable power can be reliably transmitted to the user.

In the battery status display device 20 of the first embodiment, since the charging lamp 12 that is turned on during charging is provided in the vehicle interior of the electric vehicle 10, the charging lamp 12 is turned on simultaneously with the charging of the renewable power. On the other hand, if one or more passengers are in the passenger compartment, the display form of the inner segment 21j adjacent to the inner side of the segment 21h indicating the ratio corresponding to the charged renewable power is displayed differently from the default form. To do. That is, the display form of the battery fuel gauge 21f is made different from the case where the renewable power is not charged at all in synchronization with the lighting of the charging lamp 12.
Therefore, the fact that charging is performed by selectively using renewable electric power can be reliably transmitted to the occupant on board.

Further, even when the renewable power is charged, if no occupant is in the passenger compartment of the electric vehicle 10, step S1, step S2, step S4, step S6 in the flowchart shown in FIG. → Proceeding to step S10, the battery charge amount is not displayed on the combination meter 21.
Therefore, it is possible to prevent unnecessary power consumption by turning on the combination meter 21 in a situation where no passenger is on board and no one is looking at the combination meter 21.

In the battery state display device 20 according to the first embodiment, when the display form of the inner segment 21j of the battery fuel gauge 21f is changed, at least the display color, the saturation of the display color, the brightness of the display color, and the display pattern are displayed. One is different from the default form.
Therefore, it is possible to reliably convey the fact that the renewable power is selectively used with a simple configuration, and it is possible to convey “praise” to the user without incurring costs.

  Further, in the battery status display device 20 of the first embodiment, after the charging of the renewable power is completed, the process proceeds from step S10 to step S11 in the flowchart shown in FIG. If the power is off, the process proceeds to step S12, and all the displays of the battery remaining amount indicator 21f on the combination meter 21 are turned off. Then, the process proceeds from step S14 to step S15, and the fact that the renewable power is charged via the communication device 26 and the information on the charge amount of the renewable power within the charge amount at the end of charging are passed to the external device. Send.

  As described above, by notifying the external device that the regenerative power is charged, it is possible to use the information that the regenerative power is charged in the external device to give a further merit to the user. In other words, if this external device is, for example, a parking lot management system, and the parking lot management system has set a predetermined “praise” or a monetary merit such as a discount for charging renewable power, the parking lot The management system can easily grasp the fact that the renewable power is charged. The user can then receive further merits (“praise” or financial merits).

  If the power is on after charging of the renewable power is completed, the process proceeds from step S10 to step S11 to step S13 in the flowchart shown in FIG. As a result, the display form of the battery fuel gauge 21f on the combination meter 21 is set to the default form, assuming that the electric vehicle 10 is maintained in a travelable state. For this reason, it is possible to prevent the information in the user field of view from being complicated.

[In-vehicle display when charging renewable power]
An in-vehicle display operation at the time of charging the renewable power when the electric vehicle 10 is powered off and is supplied with power including the renewable power from the charging device 100 will be described.

  At this time, in the flowchart shown in FIG. 3, the process proceeds from step S1, step S2, step S4, step S6, and step S8. Here, when it is determined that charging is started in step S <b> 1, the charging lamp 12 disposed in the passenger compartment of the electric vehicle 10 is lit.

When the display form control process is executed in step S8, it is determined in step S811 of the flowchart shown in FIG. 7 whether or not the user has permitted display on the vehicle exterior display 22. If the display is permitted, the process proceeds from step S812 to step S813, and the battery remaining amount display unit 22a is displayed in the form A ′ on the outside display 22.
Here, when the renewable power is not charged at all, the battery remaining amount display unit 22a is not displayed on the display 22 outside the vehicle. For this reason, the display form of the display 22 outside the vehicle when the renewable power is charged is different from the display form when the renewable power is not charged at all.

  Further, since the charging lamp 12 that is turned on during charging is provided in the vehicle interior of the electric vehicle 10, the charging lamp 12 is turned on simultaneously with the charging of the renewable power. The battery remaining amount display unit 22a is displayed in synchronization with the above.

  In this way, the fact that the electric vehicle 10 is charged by selectively using renewable electric power is communicated not only to the person outside the vehicle, that is, the user, but also to the other person passing near the electric vehicle 10. Can generate indirect “praise” for users.

On the other hand, if the user prohibits the display on the outside display 22, the process proceeds from step S 811 to the end in the flowchart shown in FIG. 7, and the outside display 22 is not displayed. That is, the vehicle exterior display 22 can display the battery remaining amount display part 22a according to a user's desire.
For this reason, it is possible to prevent the fact that the renewable power is selected and used unnecessarily from being transmitted unnecessarily to an irrelevant person such as another person passing in the vicinity of the electric vehicle 10.

[Power-on action when charging renewable power]
An operation in the case where power-on control is performed in the electric vehicle 10 during charging of the renewable power of the electric vehicle 10, that is, a startup control operation will be described.

  At this time, in the flowchart shown in FIG. 3, the process proceeds from step S1 to step S2 to step S4 to step S5. Then, when the start-up control process is executed in step S5, the process proceeds to step S51 in the flowchart shown in FIG. If it is less than the threshold number of times, the process proceeds to step S52, and the startup sound of the in-vehicle buzzer 30 is set to a sound A different from the default sound. And it progresses to step S54 and the start-up sound (sound A) to which the in-vehicle buzzer 30 was set sounds.

  On the other hand, when power that does not include any renewable power is supplied from the charging device 100, when only environmental load power is charged, the process proceeds from step S1 to step S2 to step S3 in the flowchart shown in FIG. . For this reason, the in-vehicle buzzer 30 sounds the startup sound with the default sound when the power-on control is performed.

Thus, the start-up sound by the in-vehicle buzzer 30 is different between when the regenerative power is charged (set to sound A) and when the reproducible power is not charged at all (set to the default sound).
Therefore, for example, even if the user does not look at the battery fuel gauge 21f of the combination meter 21, the fact that the renewable power is selectively used can be notified to the user by sounding a different start-up sound. The “praise” for the selective use of the available power is reliably transmitted to the user.

  If it is determined in step S51 of the flowchart shown in FIG. 4 that the number of continuous regenerative power chargings is equal to or greater than the threshold number, the process proceeds to step S53, where the startup sound of the in-vehicle buzzer 30 is different from the default sound and sound A. B is set. And it progresses to step S54 and the start-up sound (sound B) in which the in-vehicle buzzer 30 was set is sounded.

  Thus, when the regenerative power continuous charge count is equal to or greater than the threshold count, the regenerative power is not charged at all (set to the default sound), and when the regenerative power continuous charge count is less than the threshold count (sound A startup sound (sound B) different from the setting A) is set. Thus, the fact that the user can continue to selectively use the renewable power can be communicated even if the user has not checked the battery fuel gauge 21f. "Praise" is surely communicated to users.

Furthermore, if the vehicle speed is zero after the power-on control is performed in the electric vehicle 10 and the start-up control process is executed during charging of the renewable power of the electric vehicle 10, step S5 → step S7 in the flowchart shown in FIG. → Proceeding to step S8, display mode control processing is executed.
On the other hand, if the vehicle speed is greater than zero after the electric vehicle 10 is powered on and the startup control process is executed while the electric vehicle 10 is being charged with the renewable power, step S5 → step in the flowchart shown in FIG. Proceeding from S7 to step S9, the battery fuel gauge 21f of the combination meter 21 is displayed in a preset default form.
For this reason, the amount of information in the user's field of view can be reduced and driving can be facilitated while the battery fuel gauge 21f is traveling with relatively few opportunities to be watched.

  In the battery status display device 20 according to the first embodiment, as a display unit that displays the remaining battery level in the state of the battery 11, a battery fuel gauge 21f of the combination meter 21 provided in the passenger compartment of the electric vehicle 10, The vehicle 10 has an outside display 22 provided on the outer surface of the vehicle body and a portable mobile terminal display 23.

  Therefore, it is possible to inform the user of the fact that the renewable power is selectively used using the existing display means, and the “praise” for the selective use of the renewable power without incurring costs is sure to the user. Can tell.

Next, the effect will be described.
In the battery state display device of Example 1, the effects listed below can be obtained.

(1) The state (remaining battery level) of a driving battery (battery) 11 mounted on an electric vehicle (electric vehicle) 10 that uses electricity as at least a part of a driving source is displayed by a display means (battery remaining amount meter) 21f. In the battery status display device 20 to display,
The display form (form A) of the display means (battery fuel gauge) 21f when the renewable power generated without discharging carbon dioxide is charged is the same as the case where the renewable power is not charged at all. The display means (display controller) 24 is configured to be different from the display form (default form) of the display means (battery remaining amount meter) 21f.
As a result, it is possible to make the user recognize that the renewable power is used and to actively and continuously select and use the renewable power.

(2) The display control means (display controller) 24 displays the display form (form B) of the display means (battery remaining amount meter) 21f when the number of continuous charges of the renewable power is equal to or greater than a preset threshold number.

(4) The display control means (display controller) 24 includes any one of a segment (inner segment) 21jα that displays the charge amount of the renewable power and a segment (inner segment) 21jβ that displays the charge amount of the environmental load power. When the power amount in the driving battery (battery) 11 is reduced when the light is on, the environmental load power is more than the segment (inner segment) 21jα that displays the charge amount of the renewable power when the power amount in the driving battery (battery) 11 decreases. The segment (inner segment) 21jβ that displays the amount of charge is turned off first.
Thereby, until the battery remaining amount becomes zero, the fact that the regenerative power is selectively used and manually charged can be continuously displayed on the battery remaining amount meter 21f.

(5) When the electric vehicle (electric vehicle) 10 is powered on, the display control means (display controller) 24 is charged with the renewable power when the vehicle speed is equal to or less than a threshold speed (zero) set arbitrarily. The display form (form A) of the display means (battery fuel gauge) 21f in the case of the battery is the same as the display form (default form) of the display means (battery fuel gauge) 21f when the renewable power is not charged at all. ).
As a result, the amount of information in the user's field of view can be reduced and driving can be facilitated while the battery fuel gauge 21f is traveling with relatively few opportunities to be watched.

(6) When the display control means (display controller) 24 changes the display form of the display means (battery remaining amount indicator) 21f, the display color or display color on the display means (battery remaining amount indicator) 21f In this case, at least one of the saturation, the luminance of the display color, or the display pattern is changed.
As a result, the fact that the renewable power is selected and used can be reliably transmitted with a simple configuration, and “praise” can be transmitted to the user without incurring costs.

(7) The display control means (display controller) 24 is configured to notify an external device that the renewable power has been charged.
Thereby, a further merit can be given to a user using information in which renewable electric power was charged in an external device.

(8) The electric vehicle (electric vehicle) 10 includes in-vehicle action means (in-vehicle buzzer) 30 that is driven when the electric vehicle (electric vehicle) 10 is powered on.
The display control means (display controller) 24 indicates the action mode (sound A) of the in-vehicle action means (in-vehicle buzzer) 30 when the regenerative power is charged, and the regenerative power is not charged at all. The action configuration (default sound) of the in-vehicle action means (in-vehicle buzzer) 30 is different.
Thereby, even if the user does not visually check the battery fuel gauge 21f, the fact that the renewable power is selectively used can be notified to the user.

(9) The display control means (display controller) 24 is an action form (sound B) of the in-vehicle action means (in-vehicle buzzer) 30 when the renewable power is continuously charged more than a threshold number of times set arbitrarily. The action mode (sound A) of the in-vehicle action means (in-vehicle buzzer) 30 when the number of continuous charges of the renewable power is less than the threshold number, and the case where the renewable power is not charged at all The action configuration (default sound) of the in-vehicle action means (in-vehicle buzzer) 30 is different.
Thereby, even if the user does not visually check the battery fuel gauge 21f, it is possible to inform the user of the fact that the renewable power is continuously used.

(10) The display means is provided on a battery condition meter (battery fuel gauge) 21f provided in a passenger compartment of the electric vehicle (electric vehicle) 10 and a vehicle body outer surface 10a of the electric vehicle (electric vehicle). In addition, the configuration includes at least one of the outside display 22 and the portable terminal display 23 that is portable.
Thereby, by using the existing display means, it is possible to inform the user of the fact that the renewable power is selectively used without cost.

(11) The electric vehicle (electric vehicle) 10 includes a charging lamp 12 that is provided in a vehicle interior and lights during charging.
The display means includes a battery condition meter (battery remaining amount meter) 21f provided in a passenger compartment of the electric vehicle (electric vehicle) 10.

As long as they do not deviate, design changes and additions are permitted.

  In the first embodiment, an example in which the state of the battery 11 is the remaining battery level monitored by the battery controller is shown, but the present invention is not limited to this. For example, it may be battery capacity or battery temperature. If it is the information which shows the state of the battery 11, it will become an important matter in an electric vehicle, and the display means which displays it is frequently watched by the user. It is possible to make the user recognize that the user is using renewable power at a high frequency.

  In the first embodiment, the battery condition meter provided in the vehicle is the battery fuel gauge 21f provided in the combination meter 21.
