To suppress frequent lift-up/down movement.SOLUTION: A power supply system includes a plurality of charging stations which can supply power to an electric vehicle on a ground surface. Each charging station includes: a power supply unit which supplies power to the electric vehicle; a movable unit which can be displaced between a first position (a position corresponding to a lower limit state) including the power supply unit accommodated under the ground surface and a second position (a position corresponding to an upper limit state) having the power supply unit exposed on the ground surface; an actuator which displaces the movable unit; and a control device which controls the actuator. On condition that there is no power supply schedule to the next electric vehicle within a predetermined period after the power supply is completed, the control device controls the actuator to lift down the movable unit to the first position (a step S333), whereas on condition that there is a power supply schedule to the next electric vehicle within a predetermined period after the power supply is completed, the control device controls the actuator to maintain the movable unit at the second position (inhibiting the execution of the processing of step S333).SELECTED DRAWING: Figure 5 【課題】昇降動作が頻繁になることを抑制すること。【解決手段】給電システムは、地面上の電動車両に給電可能な複数の充電スタンドを含む給電システムである。充電スタンドは、電動車両に給電するための給電部と、給電部を含み給電部が地面下に収納された第１位置（下限状態に相当する位置）と、給電部が地面上に露出した第２位置（上限状態に相当する位置）との間で変位可能な可動部と、可動部を変位させるアクチュエータと、アクチュエータを制御する制御装置とを備える。制御装置は、給電が終了した後、所定期間以内に次の電動車両への給電の予定が無いことを条件として、可動部を第１位置まで下降させるようアクチュエータを制御し（ステップＳ３３３）、給電が終了した後、所定期間以内に次の電動車両への給電の予定が有ることを条件として、可動部を第２位置で維持するようアクチュエータを制御する（ステップＳ３３３の処理の実行を禁止）。【選択図】図５
