To provide a cart power supply device capable of notifying a user whether or not charging is being performed.SOLUTION: A cart power supply device according to one embodiment comprises a power supply resonance circuit, a notification element, a current detection circuit, and a power supply control circuit. The power supply resonance circuit comprises a power supply coil which electromagnetically couples with a power reception coil of a power reception device which charges a secondary battery mounted on a cart. The current detection circuit detects a current flowing through the power supply resonance circuit. The power supply control circuit: supplies an AC current to the power supply resonance circuit; operates the notification element in the first operation mode when a detection result of the current detection circuit is less than a preset power supply execution threshold value; operates the notification element in a second mode different from the first operation mode when the detection result of the current detection circuit is equal to or more than the power supply execution threshold value; and supplies power to the power reception device by the power supply resonance circuit.SELECTED DRAWING: Figure 1
【課題】 充電が行われているか否かをユーザに報知することが可能なカート給電装置を提供する。【解決手段】 一実施形態に係るカート給電装置は、給電共振回路と、報知用素子と、電流検出回路と、給電制御回路と、を具備する。給電共振回路は、カートに搭載された二次電池を充電する受電装置の受電コイルと電磁結合する給電コイルを有する。電流検出回路は、前記給電共振回路に流れる電流を検出する。給電制御回路は、前記給電共振回路に交流電流を供給し、前記電流検出回路の検出結果が予め設定された給電実行閾値未満である場合、第1の動作モードで前記報知用素子を動作させ、前記電流検出回路の検出結果が前記給電実行閾値以上である場合、第1の動作モードとは異なる第2のモードで前記報知用素子を動作させ、前記給電共振回路により前記受電装置への給電を行う。【選択図】 図1
