To provide a technique for optimizing the use of electric energy from a holistic perspective including use objects such as a power system and an electric vehicle when the electric vehicle is used.SOLUTION: A charging suggestion system is a system that makes suggestions regarding charging an electric vehicle when the electric vehicle is charged from a power system whose power supply state fluctuates. In the charging suggestion system, a power supply determination unit 21 determines that the power supply state of the power system is in a surplus time period, which indicates a time period when there is a certain amount of surplus power or more. A charging prediction unit 23 predicts a required charging time, which indicates a time when a state of a battery of the electric vehicle meets a condition that requires a certain amount of charging. A charging suggestion unit 25 makes suggestions on the state in which the battery power is consumed and/or suggestions on adjustments to the timing of charging the battery such that the battery can be charged in the surplus time period on the basis of the required charging time.SELECTED DRAWING: Figure 5

    【課題】電気自動車を使用する場合に、電力システムや電気自動車等の利用対象を含む全体の視点で、電力エネルギーの利用の最適化を図る技術を提供すること。【解決手段】充電提案システムは、電気自動車が電力の供給状態が変動する電力システムから充電を受ける場合に、電気自動車の充電に関する提案を行うシステムである。この充電提案システムでは、電力供給判断部21は、電力システムの電力の供給状態が所定以上の余力のある状態の時間帯を示す余力時間帯であることを判断する。充電予測部23は、電気自動車のバッテリの状態が所定の充電が必要な条件を満たす時刻を示す充電必要時刻を予測する。充電提案部25は、充電必要時刻に基づいて余力時間帯にてバッテリの充電が可能なように、バッテリの電力を消費する状態の提案及び/又はバッテリに充電するタイミングの調整の提案を行う。【選択図】図5
