To accurately evaluate the state of deterioration of a secondary battery.SOLUTION: A vehicle 1 comprises: a battery 60 that is mounted on the vehicle 1 as a power source; and an instrumental panel 80 that displays an index (icon) indicating the capacity maintenance ratio R of the battery 60 that is the current capacity of the battery 60 to a predetermined reference capacity. The reference capacity is determined based on a virtual capacity of the battery 60 when a predetermined period elapses after the manufacture of the vehicle 1.SELECTED DRAWING: Figure 6

    【課題】二次電池の劣化状態を正確に評価する。【解決手段】車両1は、車両1に動力源として搭載されたバッテリ60と、予め定められた基準容量に対する現時点におけるバッテリ60の容量の比率であるバッテリ60の容量維持率Rを示す指標(アイコン)を表示するインパネ80とを備える。基準容量は、車両1の製造後に所定期間が経過した場合のバッテリ60の仮想容量に基づいて定められる。【選択図】図6
