Control unit 206 changes the display on display unit 204 in accordance with the changed data of the charging schedule.

  FIG. 3 is a view showing a display state of the display unit 204 of FIG. The screen of display unit 204 includes a first display area 300 in which a charge schedule of power storage device 150 is displayed. The first display area 300 is partitioned in the horizontal and vertical directions in a matrix. In the illustrated example, the first display area 300 is divided into seven sections in the horizontal direction and is divided into 24 sections in the vertical direction. Seven horizontal sections of the first display area 300 correspond to Monday to Sunday, and twenty-four vertical sections correspond to 24 hours of each day of the week. That is, one section in the vertical direction represents one hour.

  The charging schedule is displayed using a first icon 302 and a second icon 304, which are arranged in the first display area 300, and represent a plurality of charging schedules. The first icon 302 and the second icon 304 have different colors and / or shapes from each other. Here, the first icon 302 and the second icon 304 have different colors and shapes.

  The first icon 302 corresponds to the charge reservation for specifying the end time, that is, the charge reservation for specifying the departure time. The first icon 302 is, for example, a home base type green (first color) pentagon having a vertex on the lower side, and the color becomes lighter toward the upper side. That is, the first icon 302 is displayed in gradation. In the first icon 302, the characters "depart" are displayed.

  The second icon 304 corresponds to the charge reservation of start time designation. The second icon 304 is, for example, a blue (second color) rectangle, and the color becomes lighter toward the lower side. That is, the second icon 304 is displayed in gradation. In the second icon 304, the characters "start" are displayed.

  The plurality of first icons 302 and second icons 304 each represent a charging schedule. Specifically, the horizontal position of the first icon 302 represents the day of the week to be charged, the upper position of the first icon 302 represents the tentative scheduled charging start time, and the position of the lower vertex is the scheduled charging end. Represents the time of day. The position in the horizontal direction of the second icon 304 represents the day of the week scheduled for charging, the position of the upper side of the second icon 304 represents the scheduled charging start time, and the lower position represents the tentative scheduled charging end time.

  In the first display area 300, a current date and time icon 306 indicating the current date and time is displayed. In the illustrated example, the current date and time icon 306 represents twelve o'clock on Tuesday. The current date and time icon 306 moves according to the passage of time. The section of the first display area 300 corresponding to the date and time before the current date and time icon 306 represents the week following the current date and time.

Next, the operation of display device 200 and the charging operation of hybrid vehicle 1 will be described.
Since hybrid vehicle 1 is a vehicle that can be externally charged, hybrid vehicle 1 using the power stored in power storage device 150 by storing as much power as possible in power storage device 150 after traveling is completed. Can increase the distance it can travel.

  On the other hand, generally, in a secondary battery used as power storage device 150, it is not preferable from the viewpoint of characteristic deterioration that the state of high SOC continues for a long time. Therefore, when charge reservation of end time designation is designated as the charge reservation type, control unit 206 and ECU 170 set power storage device 150 such that the SOC becomes fully charged immediately before the scheduled charge end time set by the user. Execute charge control (timer charge control).

  The user inputs a plurality of charging schedules by performing a touch operation on a setting screen whose illustration of the display unit 204 is omitted in advance.

  When a charge reservation of end time designation is set as the charge reservation type, the control unit 206 subtracts a predetermined expected maximum charge time, for example, 4 hours, from the set scheduled charge end time, and subtracts it. Set the result as a tentative scheduled charging start time. Thereby, the position of the first icon 302 is determined.

The control unit 206 causes the display unit 204 to lightly display the side representing the temporary scheduled charging start time with respect to the side representing the scheduled charging end time, with respect to the side representing the scheduled charging end time. As a result, the user can more intuitively understand that the first icon 302 represents the charge reservation of the end time designation.
The charge reservation for specifying the end time may be set, for example, on a day on which a scheduled departure time is predetermined.

  When the charge reservation of start time designation is set as the charge reservation type, the control unit 206 adds the expected maximum charge time to the set scheduled charge start time, and adds the result to a provisional planned charge end time Set as. Thereby, the position of the second icon 304 is determined.

The control unit 206 causes the display unit 204 to display the color of the second icon 304 representing the charging reservation designated by the start time with respect to the side representing the scheduled charging start time on the side representing the temporary scheduled charging end time. As a result, the user can more intuitively understand that the second icon 304 represents the charge reservation specified by the start time.
For example, if the scheduled time of departure is not fixed, but you want to charge in a time zone where the power charge is cheap, set the date for the scheduled charging start time in advance. May be

  In the illustrated example, the current date and time is 12 o'clock on Tuesday. The color of the first icon 302 on Wednesday representing the latest charging schedule is, for example, orange (third color), which is different from the colors of the other first icon 302 and second icon 304. Therefore, the user can easily grasp the latest charging schedule.

  The user confirms the first icon 302 or the second icon 304 representing the latest charging schedule, and the temporary scheduled charging start time represented by the first icon 302 or the scheduled charging start time represented by the second icon 304 Before, the charge inlet 190 and the external power supply are connected by the charge cable.

  In the case where the charging schedule type of the latest charging schedule is the charging schedule of the end time designation, the control unit 206 calculates the actual scheduled charging start time when the current date and time reaches the temporary scheduled charging start time. Specifically, based on the SOC of power storage device 150 acquired from ECU 170, control unit 206 calculates the necessary charge amount for charging power storage device 150 to the fully charged state. Next, the control unit 206 calculates the charging time based on the obtained required charge amount, the voltage of the external power supply, and the like. Next, the control unit 206 subtracts the charging time from the scheduled charging end time, and sets the subtraction result as the actual scheduled charging start time. Since the temporary scheduled charging start time is determined based on the expected maximum charging time, the actual scheduled charging start time is after the temporary scheduled charging start time.

  The control unit 206 notifies the ECU 170 when the current date and time becomes the actual scheduled charging start time. In accordance with the notification from control unit 206, ECU 170 causes charger 180 to charge power storage device 150 with the power of the external power supply. As a result, at the scheduled charging end time set by the user, the SOC becomes almost 100%, and traveling can be started at an appropriate timing.

  On the other hand, when the charging reservation type of the latest charging schedule is the charging reservation of start time designation, the control unit 206 notifies the ECU 170 when the current date and time becomes the charging start scheduled time, and causes the charger 180 to charge. After charging for a charging time corresponding to the SOC and the like of power storage device 150, SOC is almost 100%.

  The air conditioner interlocking can also be set to be on or off in association with each of the first icon 302 and the second icon 304. This setting is not displayed on the first icon 302 and the second icon 304, but may be displayed. When air conditioner interlocking is set to on, the air conditioner operates a predetermined time before the scheduled charging end time.

  In addition, when the current date and time reaches the scheduled charging start time, charging is not performed if the charging inlet 190 and the external power supply are not connected by the charging cable. In this case, the ECU 170 notifies the control unit 206, and the control unit 206 causes the display unit 204 to display that charging has failed.

Next, the change of the charging schedule will be described.
FIG. 4 is a diagram showing a display state of the display unit 204 of FIG. 2 when changing the charging schedule. By touching the desired first icon 302 or second icon 304, as shown in FIG. 4, a plurality of setting icons are displayed in the second display area 320 below the first display area 300. Here, the first icon 302 of Friday is touched.

  The second display area 320 includes a first setting icon 322 for selecting a charge reservation type, a second setting icon 324 for specifying a time, a third setting icon 326 for specifying ON / OFF of air conditioner interlocking, and repetition. A fourth setting icon 328 to be designated is displayed.

  The user can change the charging schedule of the first icon 302 on Friday by touching the first setting icon 322 or the like. For example, when a charge reservation specified by start time is designated as the charge reservation type by the first setting icon 322, the time set by the second setting icon 324 is set as the scheduled charging start time. In addition, when Friday is selected in the fourth setting icon 328, the scheduled date and time of charging on each Friday is changed.

  Further, after touching the next schedule change icon (not shown), the next charging schedule can be changed by touching the desired first icon 302 or second icon 304. In this case, the same setting icon as that shown in FIG. 4 is displayed. For example, when the first icon 302 on Friday is touched, the next charging schedule is on Friday. Therefore, the color of the first icon 302 on Friday is changed to orange. The next charging schedule will be Friday, so there will be no Wednesday and Thursday charging. The date and time of charging schedule of the first icon 302 on Friday touched can also be changed. In this way, it is possible to change the next charging schedule with a simple operation.

  As described above, according to the present embodiment, since at least one of the color and the shape of the first icon 302 and the second icon 304 is displayed differently for each charge reservation type, charging schedules for charging on a plurality of days are displayed. Even if it does, it can be intuitively grasped which charge reservation type is set to which charge schedule. Therefore, it is possible to more easily check the change of the date and time of the specific charging schedule and whether the charging schedule of the charging schedule for multiple days is correctly set. Therefore, charging of the hybrid vehicle 1 can be appropriately performed according to the convenience of the user.

  In addition, since the color of the first icon 302 or the second icon 304 representing the latest charging schedule of the current date and time is changed to a color different from the color of the first icon 302 and the second icon 304 representing the other charging schedules. , You can easily grasp the latest charging schedule.

  Moreover, since the charge reservation of start time designation or the charge reservation of finish time designation is set as the charge reservation type, it is possible to set a charge schedule according to the convenience of the user.

  The present invention has been described above based on the embodiments. The embodiment is merely an example, and it is understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are also within the scope of the present invention.
