PROBLEM TO BE SOLVED: To provide a connection-disconnection determination device of a service plug in an electric vehicle capable of appropriately performing connection-disconnection determination even when connection-disconnection failure occurs in a switching circuit for determining a connection-disconnection state of the service plug.SOLUTION: In a case where connection-disconnection determination is performed based on a switching circuit 6 caused by disconnection failure of the switching circuit 6 even if a service plug 3 is connected, when electric leakage that is made to generate by a forcible leak circuit 11P provided with a battery 2P side is detected in an electric leakage detection circuit 10 at an N-side of a battery, the service plug 3 is supposed to be actually connected, disconnection determination based on the switching circuit 6 is corrected into connection determination, and failure determination of the switching circuit 6 is performed.SELECTED DRAWING: Figure 1

    【課題】サービスプラグの断接状態を判定するスイッチ回路に断接故障等が発生している場合であっても、的確に断接判定を実施できる電動車両におけるサービスプラグの断接判定装置を提供する。【解決手段】スイッチ回路6の断線故障に起因して、サービスプラグ3が接続されているにも拘わらずスイッチ回路6に基づき切断判定が下されている場合、バッテリ2P側に設けた強制漏電回路11Pにより発生させた漏電がバッテリN側の漏電検出回路10で検出されると、実際にはサービスプラグ3が接続されていると見なしてスイッチ回路6に基づく切断判定を接続判定に訂正すると共に、スイッチ回路6の故障判定を下す。【選択図】図1
