To achieve a power supply auxiliary system capable of determining a charging state of a secondary battery and appropriately disconnecting a connector even when information on the charging state cannot be acquired from a vehicle and a power supply unit.SOLUTION: A power supply auxiliary system 10 added to a vehicle power supply device 20 includes: a drive unit 41 for connecting and disconnecting a connector 21 to and from a power receiving port 104; a control unit 50 for controlling the drive unit 41; a voltage sensor 42 for detecting a supply voltage value Vd; and a current sensor 44 for detecting a supply current value Id. When determining that a secondary battery 102 becomes a predetermined charging state based on the supply voltage value Vd and the supply current value Id during power supply to the secondary battery 102 of the vehicle 100, the control unit 50 controls the drive unit 41 to disconnect the connector 21.SELECTED DRAWING: Figure 1

    【課題】車両及び給電ユニットから充電状態に関する情報を取得できない場合であっても、二次電池の充電状態を判定してコネクタの接続解除を適切に行うことができる給電補助システムを実現する。【解決手段】車両用給電装置20に付加される給電補助システム10であって、受電ポート104に対するコネクタ21の接続及び接続解除を行う駆動ユニット41と、駆動ユニット41を制御する制御ユニット50と、供給電圧値Vdを検出する電圧センサ42と、供給電流値Idを検出する電流センサ44と、を備え、制御ユニット50は、車両100の二次電池102に対する給電中に、供給電圧値Vd及び供給電流値Idに基づいて、二次電池102が予め定められた充電状態になったと判定した場合に、コネクタ21の接続解除を行うように駆動ユニット41を制御する。【選択図】図1
