Display system and vehicle including the same, and method of display of status of secondary battery

Abstract

A vehicle includes: an instrument panel; and an ECU that controls the instrument panel so that the instrument panel displays an icon representing a status of a battery. The icon represents one of a first indication and a second indication by an increase or decrease of a scale in a display region of the icon, and the other one of the first indication and the second indication by an amount indicated by a size of a display area of the icon, the first indication representing SOC of the battery, the second indication representing a full charge capacity of the battery.

What is claimed is: 
     
         1 . A display system, comprising:
 a display configured to display an icon that represents a status of a secondary battery; and   a controller configured to control the display of the icon, wherein   the icon is configured to simultaneously:
 display one of a first indication and a second indication by an increase or decrease of a scale of the icon in a display region of the display, and 
 display the other one of the first indication and the second indication by a size of a display area within the icon, wherein 
   the first indication represents a state of charge (SOC) of the secondary battery, and the second indication represents a full charge capacity of the secondary battery, wherein   the icon simultaneously represents the first indication by the increase or decrease of the scale of the icon, and the second indication by the size of the display area within the icon,   the display area decreases with a decrease of the first indication, and   the scale decreases with a decrease of the second indication.   
     
     
         2 . The display system according to  claim 1 , wherein
 the scale increases and decreases in a predetermined direction, and   the display area varies by the icon changing in shape in a direction perpendicular to the predetermined direction.   
     
     
         3 . The display system according to  claim 2 , wherein
 the shape of the icon varies in the direction perpendicular to the predetermined direction, while keeping an aspect ratio of the icon.   
     
     
         4 . The display system according to  claim 1 , wherein
 the icon has a shape comprising a profile shape of a battery case, and   the increase or decrease of the scale is displayed in a segment display.   
     
     
         5 . A vehicle, comprising:
 the secondary battery; and   the display system according to  claim 1 .   
     
     
         6 . A method for displaying a status of a secondary battery, the method comprising:
 obtaining a first indication representing a state of charge (SOC) of the secondary battery;   obtaining a second indication representing a full charge capacity of the secondary battery; and   displaying an icon representing the status of the secondary battery on a display, wherein   the icon represents one of the first indication and the second indication by an increase or decrease of a scale of the icon in a display region of the display, and the other one of the first indication and the second indication by a size of a display area of within the icon,   the icon simultaneously represents the first indication by the increase or decrease of the scale of the icon, and the second indication by the size of the display area within the icon,   the display area decreases with a decrease of the first indication, and   the scale decreases with a decrease of the second indication.
