PROBLEM TO BE SOLVED: To detect connection of a vehicle independently of a type or a condition of the connected vehicle.SOLUTION: A charge and discharge device (1) comprises: a transistor (51) connected in parallel to a resistive element (103) arranged in the middle of a charge and discharge connector connection confirmation line (32d), and that detects potential variation at a part (X) at a connector side from the resistive element; and a Zener diode (52) connected in parallel to the resistive element, and that restricts a voltage applied to the transistor.SELECTED DRAWING: Figure 2 【課題】接続される車両の車種または状態によらず、車両の接続を検出する。【解決手段】充放電装置（１）は、充放電コネクタ接続確認線（３２ｄ）の途中に配置された抵抗素子（１０３）に対して並列に接続され、抵抗素子よりもコネクタ側の部位（Ｘ）の電位変動を検出するトランジスタ（５１）と、抵抗素子に対して並列に接続され、トランジスタに印加される電圧を制限するツェナーダイオード（５２）と、を備える。【選択図】図２
