## Abstract

An information supply device includes an acquirer configured to acquire information regarding a degree of deterioration of a secondary battery for supplying travel power of a vehicle, a deriver configured to derive performance of the secondary battery based on the information acquired by the acquirer, and a display controller configured to cause a display to display an image indicating information regarding performance of the secondary battery, the performance indicated by the image being lower than the performance derived by the deriver.

## Claims

### Claim 1

An information supply device comprising:
an acquirer configured to acquire information regarding a degree of deterioration of a secondary battery for supplying travel power of a vehicle;
a deriver configured to derive performance of the secondary battery based on the information acquired by the acquirer; and
a display controller configured to cause a display to display an image indicating information regarding performance of the secondary battery, the performance indicated by the image being lower than the performance derived by the deriver,
wherein
the information regarding the degree of deterioration in the secondary battery comprises a battery capacity of the secondary battery or information for deriving the battery capacity, and
the information regarding the performance of the secondary battery comprises a travelable distance of the vehicle,
wherein
the display controller is configured to:
cause the display to display the travelable distance of the vehicle calculated based on the battery capacity in a case in which the battery capacity is less than an initial battery lower limit capacity; and
cause the display to display the travelable distance of the vehicle calculated based on the initial battery lower limit capacity instead of the battery capacity in a case in which the battery capacity is equal to or greater than the initial battery lower limit capacity.

### Claim 2 (depends on 1)

The information supply device according to claim 1, wherein the deriver is configured to:
derive a deterioration ratio of the secondary battery based on the information regarding the degree of deterioration of the secondary battery; and
derive a residual lifetime until the derived deterioration ratio reaches a predetermined deterioration ratio as information indicating the performance of the secondary battery.

### Claim 3 (depends on 2)

The information supply device according to claim 2, wherein the display controller is configured to cause the display to display a residual lifetime shorter than the residual lifetime derived by the deriver as a display residual lifetime.

### Claim 4 (depends on 3)

The information supply device according to claim 3, wherein the deriver is configured to:
calculate an actual residual lifetime of a secondary battery mounted in a target vehicle; and
correct the actual residual lifetime to be shorter than that of the secondary battery mounted in the target vehicle to derive the display residual lifetime.

### Claim 5

An information supply method comprising the steps of:
acquiring, by a computer, information regarding a degree of deterioration of a secondary battery for supplying travel power of a vehicle;
deriving, by the computer, performance of the secondary battery based on the acquired information; and
causing, by the computer, a display to display an image indicating information regarding performance of the secondary battery, the performance indicated by the image being lower than the derived performance,
wherein
the information regarding the degree of deterioration in the secondary battery comprises a battery capacity of the secondary battery or information for deriving the battery capacity, and
the information regarding the performance of the secondary battery comprises a travelable distance of the vehicle,
wherein
the causing of the display to display the image comprises:
causing the display to display the travelable distance of the vehicle calculated based on the battery capacity in a case in which the battery capacity is less than an initial battery lower limit capacity; and
causing the display to display the travelable distance of the vehicle calculated based on the initial battery lower limit capacity instead of the battery capacity in a case in which the battery capacity is equal to or greater than the initial battery lower limit capacity.

### Claim 6

A non-transitory computer-readable storage medium that stores computer executable program instructions by a computer to perform at least:
acquiring information regarding a degree of deterioration of a secondary battery for supplying travel power of a vehicle;
deriving performance of the secondary battery based on the acquired information; and
causing a display to display an image indicating information regarding performance of the secondary battery, the performance indicated by the image being lower than the derived performance,
wherein
the information regarding the degree of deterioration in the secondary battery comprises a battery capacity of the secondary battery or information for deriving the battery capacity, and
the information regarding the performance of the secondary battery comprises a travelable distance of the vehicle,
wherein
the causing of the display to display the image comprises:
causing the display to display the travelable distance of the vehicle calculated based on the battery capacity in a case in which the battery capacity is less than an initial battery lower limit capacity; and
causing the display to display the travelable distance of the vehicle calculated based on the initial battery lower limit capacity instead of the battery capacity in a case in which the battery capacity is equal to or greater than the initial battery lower limit capacity.
