Abstract
Disclosed herein is a relay module for a vehicle battery system. The relay module includes a movable unit configured to be moved by a magnetic field generated by a coil and a return spring within a relay. This movable unit controls a state of an electrical connection between relay electrodes. A microsensor installed between the movable unit and a fixed unit maintains a fixed location relative to the movable unit and is configured to induce a variation in an electrical physical quantity depending on a variation in a location of the movable unit relative to the fixed unit.
Claims16
A relay module for a vehicle battery system, comprising:
- a movable unit configured to be moved via a magnetic field generated by a coil and a return spring within a relay and to control a state of an electrical connection between relay electrodes;
- and
- a microsensor installed between the movable unit and a fixed unit, the microsensor maintaining a fixed location relative to the movable unit, and configured to induce a variation in an electrical physical quantity depending on a variation in a location of the movable unit relative to the fixed unit,
- wherein the microsensor comprises:
- two sensing electrodes spaced apart from each other at a predetermined distance to enable an electrical resistance therebetween to be measured;
- a sensing contact member configured to, when the movable unit moves in a direction enabling the relay electrodes to be electrically connected to each other, move in a direction identical to that of the movable unit, to enable the two sensing electrodes to be electrically connected to each other;
- a measurement unit including the two sensing electrodes spaced apart from each other to enable an electrical resistance therebetween to be measured, and the sensing contact member configured to, when the movable unit moves in a direction enabling the relay electrodes to be electrically connected to each other, move in a direction identical to that of the movable unit and then enable the two sensing electrodes to be electrically connected to each other;
- and
- a reference unit including two reference electrodes spaced apart from each other to enable an electrical resistance therebetween to be measured, and an operation unit configured to,
- when the movable unit moves in a direction enabling the relay extrudes to be electrically connected to each other, move in a direction identical to that of the movable unit while operating in conjunction with the measurement unit.
