Title:
ELECTRIC VEHICLE POWER RELAY ASSEMBLY AND METHOD FOR DRIVING SAME
Document Type and Number:
WIPO Patent Application WO/2018/093217
Kind Code:
A1
Abstract:
The present invention relates to an electric vehicle power relay assembly and a method for driving the same and, specifically, to an electric vehicle power relay assembly, which performs a pre-charge process by means of a semiconductor switch, instead of a gas filled type relay used as a pre-charge relay, and a method for driving the same. Further, the present invention comprises: a main relay; a pre-charge relay comprising a semiconductor switching element; a gate voltage supply unit for supplying a gate voltage to turn on the pre-charge relay before the main relay is turned on, and to turn on the pre-charge relay before the main relay is turned off; and a control unit for controlling the gate voltage supply unit. Therefore, the present invention allows performance of a pre-charge process by means of a semiconductor switch instead of an existing gas filled type relay.
