To display a power suppliable time when power is supplied to outside from a vehicle with resolution finer than resolution of SOC.SOLUTION: A power suppliable time display device of a vehicle mounted with a battery capable of supplying power to outside acquires SOC of a battery during power supply to outside, SOC value changing by a first predetermined width unit, calculates first power suppliable time corresponding to a latest SOC value from the latest SOC value when the SOC value changes, calculates second power suppliable time obtained by subtracting elapsed time from the time point when the SOC value measured by a second predetermined width unit shorter than the first predetermined width changes, from the first power suppliable time, and displays the second power suppliable time as a residual power suppliable time, until the SOC changes to a next value reduced by the first predetermined width from the latest SOC value.SELECTED DRAWING: Figure 2 【課題】 車両から外部への給電の際の給電可能時間をＳＯＣの分解能に対応する分解能よりも細かい分解能にて表示できるようにする。【解決手段】 外部に給電可能なバッテリを搭載した車両の給電可能時間表示装置は、外部への給電中にバッテリの、値が第一の所定幅単位にて変化するＳＯＣを取得し、ＳＯＣの値が変化した時点でＳＯＣの最新の値から該最新の値に対応する第一の給電可能時間を算出し、第一の所定幅よりも短い第二の所定幅単位にて計測されたＳＯＣの値が変化した時点からの経過時間を、第一の給電可能時間から差し引いて得られた第二の給電可能時間を算出し、ＳＯＣが最新の値から第一の所定幅にて低減した次の値に変化するまで、第二の給電可能時間を給電可能残り時間として表示する。【選択図】 図２
