To provide an electrification control device that achieves both speedy disconnection and erroneous detection prevention in order to disconnect an inter-system switch upon detection of a ground fault.SOLUTION: An electrification control device comprises an inter-system switch (an inter-system SW) and an SW control circuit as an inter-system switch control unit. The inter-system SW switches between electrification and disconnection for current between an inter-system bus. The SW control circuit controls an actuating state of the inter-system SW. The SW control circuit has: a current acquisition unit by step S40, a disconnection control unit by step S60, a status acquisition unit by step S20, and a threshold change unit by step S30. In a case where a current value Ismr acquired by the current acquisition unit increases beyond an anomaly threshold IsmrTH, the disconnection control unit determines that a ground-fault anomaly has been arising and disconnects the inter-system SW. The threshold change unit changes the anomaly threshold IsmrTH according to a sub power source voltage Vs (a system status value) acquired by the status acquisition unit.SELECTED DRAWING: Figure 3

    【課題】地絡発生を検知したら系統間スイッチを遮断するにあたり、迅速な遮断と誤検知抑制の両立を図った通電制御装置を提供する。【解決手段】通電制御装置は、系統間スイッチ(系統間SW)と、系統間スイッチ制御部としてのSW制御回路と、を備える。系統間SWは、系統間バスにおける電流の通電と遮断を切り替える。SW制御回路は、系統間SWの作動状態を制御する。SW制御回路は、ステップS40による電流取得部と、ステップS60による遮断制御部と、ステップS20による状態取得部と、ステップS30による閾値変更部とを有する。遮断制御部は、電流取得部により取得された電流値Ismrが異常閾値IsmrTHを超えて上昇した場合に、地絡異常が生じているとみなして系統間SWを遮断する。閾値変更部は、状態取得部により取得されたサブ電源電圧Vs(システム状態値)に応じて、異常閾値IsmrTHを変更させる。【選択図】図3
