To enable the detection of the short-circuit state of electrodes in a current collector during the execution of power supply during traveling.SOLUTION: A vehicle-side short-circuit detection system mounted on a vehicle includes: collector electrodes 212+ and 212- which are brought into contact with road-surface electrodes laid on a road surface to receive power from the road-surface electrodes; a power reception circuit 220 which converts the power received by the collector electrodes into power allowing a battery mounted on the vehicle to be charged; a short-circuit detection circuit 230 which is arranged between the collector electrode and the power reception circuit to acquire a detection value Vpd varying according to the magnitude of a current flowing through the short-circuit detection circuit; and a control device 250 which, when a short-circuit detection start condition is satisfied, operates the short-circuit detection circuit to perform the detection of a short circuit and acquire the detection value, and which, if the acquired detection value exceeds a short-circuit determination threshold, prohibits power supply from the road-surface electrodes.SELECTED DRAWING: Figure 1

    【課題】走行中給電の実行中において集電装置の電極の短絡状態を検知可能とする。【解決手段】車両に搭載された車両側短絡検知システムは、路面に敷設された路面電極に接触して前記路面電極から電力を受ける集電電極212+,212−と、前記集電電極で受電した電力を前記車両に搭載されたバッテリに充電可能な電力に変換する受電回路220と、前記集電電極と前記受電回路との間に配置された短絡検知回路230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、前記路面電極からの給電を禁止させる制御装置250と、を備える。【選択図】図1
