Title:
RELAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/179414
Kind Code:
A1
Abstract:
Provided is a relay device capable of switching on and switching off a current flow route between power storage units and performing a protective operation while suppressing output degradation of the storage units when there is an abnormality such as a ground fault. The relay device (1) is equipped with: a current flow path (11); switch units (20), each being used for switching between an on state in which a current is caused to flow through the current flow path (11) and an off state in which the current flow path (11) is set to a predetermined non-current flow state; a coil (inductance part) (30) which is connected in series with each switch unit (20); a first voltage detection unit (61) for detecting the voltage of the current flow path (11) on a first storage unit (91) side; a second voltage detection unit (62) for detecting the voltage of the current flow path (11) on a second storage unit (92) side; and a control unit (3) for switching the switch units (20) to the off state when a detection value of the first voltage detection unit (61) and/or of the second voltage detection unit (62) indicates a predetermined abnormal value.
