A method of displaying a residual capacity of a secondary battery causes a computer of a display device to perform calculating a residual capacity of a secondary battery that is configured to store electric power for driving a motor-driven vehicle on the basis of at least an estimated value of an open-circuit voltage of the secondary battery storing the residual capacity of the secondary battery which is calculated at the time of stopping of supply of electric power of the secondary battery in a storage and displaying the residual capacity at the time of stopping of supply of electric power of the secondary battery, which is stored in the storage, on a display at the time of starting of supply of electric power of the secondary battery and subsequently displaying the residual capacity of the secondary battery on the display within a range with a predetermined upper limit value and a predetermined lower limit value with respect to the residual capacity at the time of stopping of supply of electric power of the secondary battery.

A display device includes: an acquisition unit configured to acquire information on a use status of a battery that stores electric power for traveling of a vehicle; a display unit configured to display an image; and a display control unit configured to cause the display unit to display an image in which a state of the battery is represented by an anthropomorphic character based on an acquisition result of the acquisition unit.

A fuel system controller obtains fuel burn data from an engine control module (ECM). The fuel system controller also obtains location data from a telematics control module, such as GPS location data identifying the location of a vehicle. The fuel system controller determines the vehicle's base location based on the location data, and determines how far the vehicle can travel based on the fuel burn data. The fuel system controller determines how many fueling stations are with a threshold distance of the determined distance to empty. The fuel system controller can use that data to identify which, and how many, fueling stations are within a threshold distance of the determined distance to empty. The fuel system controller can provide a fueling warning indication based on the number of fueling stations that are within the determined distance to empty.
