To enable detection of short-circuiting of a power supply electrode at power supply during traveling.SOLUTION: A power supply side short-circuiting detection system provided to a power supply device that supplies power to a vehicle includes: a road surface electrode 110 that supplies power to a current collector electrode that is mounted in the vehicle while the road surface electrode 110 is in contact with the current collector electrode; a power supply circuit 120 that outputs the power, which is supplied to the vehicle, to the road surface electrode; and a short-circuiting detection circuit 130 disposed between the road surface electrode and the power supply circuit for obtaining a detection value Vpd that changes in accordance with the amount of current flowing in the short-circuiting detection circuit; and a control device 160 that, when a short-circuiting detection starting condition is satisfied, operates the short-circuiting detection circuit to detect the short-circuiting and acquire the detection value, and when the acquired detection value is more than a short-circuiting determination threshold, prohibits the power supply to the road surface electrode.SELECTED DRAWING: Figure 1

    【課題】走行中給電の実行中において給電用の電極の短絡を検知可能とする。【解決手段】車両に電力を供給する給電装置に設けられた給電側短絡検知システムは、車両に搭載された集電電極に接触して前記集電電極に電力を供給する路面電極110と、前記車両に供給する電力を前記路面電極に出力する給電回路120と、前記路面電極と前記給電回路との間に配置された短絡検知回路130であって、前記短絡検知回路を流れる電流の大きさに従って変化する検出値Vpdを得るための短絡検知回路と、短絡検知開始条件が満たされた際に、前記短絡検知回路を動作させて短絡の検知を行なって前記検出値を取得し、取得した前記検出値が短絡判定閾値を越えている場合に、前記路面電極への給電を禁止させる制御装置160と、を備える。【選択図】図1
