## Abstract

In representation processing, when a capacity retention is higher than a threshold value while a warranty condition is satisfied, an ECU has the capacity retention shown in a first manner. When the capacity retention is equal to or lower than the threshold value while the warranty condition is satisfied, the ECU has the capacity retention shown in a second manner.

## Claims

### Claim 1

A display system comprising:
a display apparatus that shows a first indicator relating to a full charge capacity of a secondary battery; and
a controller that controls the display apparatus, wherein
the controller controls the display apparatus to notify, when a full charge capacity of the secondary battery is equal to or lower than a threshold value, that the full charge capacity of the secondary battery is equal to or lower than the threshold value,
the display apparatus is configured to notify that accuracy of the first indicator is low, and
when a left-stand time period of the secondary battery is a first time period, the accuracy of the first indicator is lower as compared to when the left-stand time period is a second time period that is longer than the first time period.

### Claim 2

A method of showing a state of a secondary battery by showing a first indicator relating to a full charge capacity of the secondary battery, the method comprising:
obtaining a full charge capacity of the secondary battery;
notifying, when the full charge capacity of the secondary battery is equal to or lower than a threshold value, that the full charge capacity of the secondary battery is equal to or lower than the threshold value; and
notifying that accuracy of the first indicator is low, wherein
when a left-stand time period of the secondary battery is a first time period, the accuracy of the first indicator is lower as compared to when the left-stand time period is a second time period that is longer than the first time period.
