Abstract
A power relay assembly for an electric vehicle and a driving method thereof according to an embodiment of the present invention connect the first switching unit and the second switching unit connected in series with each other in parallel with the relay switch, and by allowing the first switching unit and the second switching unit to include semiconductor switching elements and diodes therein, not only when power is supplied from the battery to the load side, but also when charging is performed by supplying a charging current to the battery, it is possible to supply or cut off power while preventing sparks and arcs at the relay contact point.
