To suppress the user's discomfort in display of the remaining battery capacity of a battery that can set the charging mode in which the charging is completed when the battery is charged to a predetermined remaining battery capacity lower than the full charge.SOLUTION: A power-assisted vehicle includes a display device that displays the remaining battery capacity, a battery pack that can set either a first charge mode in which a battery cell is charged until the battery is fully charged, or a second charge mode in which charging is completed when the battery cell is charged to a predetermined remaining battery capacity lower than the full charge, and a control device that cause the display device to display the remaining battery capacity on the basis of the current remaining battery capacity notified from the battery pack when the charging mode notified from the battery pack is the first charging mode, and adjusts the current remaining battery capacity notified from the battery pack when the charge mode notified from the battery pack is a second charge mode, and causes the display device to display the battery remaining capacity on the basis of the adjusted remaining battery capacity.SELECTED DRAWING: Figure 4 【課題】満充電よりも低い所定のバッテリ残容量まで充電すると充電を完了する充電モードが設定可能なバッテリのバッテリ残容量の表示をユーザの違和感を抑制する。【解決手段】電動アシスト車は、バッテリ残容量の表示を行う表示装置と、満充電となるまで電池セルを充電する第１の充電モードと、満充電よりも低い所定のバッテリ残容量まで電池セルを充電すると充電を完了する第２の充電モードとのいずれかを設定可能なバッテリパックと、バッテリパックから通知された充電モードが第１の充電モードである場合には、バッテリパックから通知された現在のバッテリ残容量を基に、表示装置にバッテリ残容量の表示を行わせ、バッテリパックから通知された充電モードが第２の充電モードである場合には、バッテリパックから通知された現在のバッテリ残容量を調整し、当該調整されたバッテリ残容量を基に、表示装置にバッテリ残容量の表示を行わせる制御装置とを有する。【選択図】図４
