Abstract

A power relay assembly is provided. A power relay assembly according to an exemplary embodiment of the present invention comprises: an upper case having at least one electric element mounted on one surface thereof; a lower case coupled to the upper case; and at least one bus bar electrically connected to the electric element, disposed between the upper case and the lower case, and including a bottom portion that is in surface contact with at least one of the upper case and the lower case, wherein at least one side of the bottom portion contacts a portion made of a plastic material having heatdissipation and insulation properties in the upper case and the lower case.

Description

technical field [0001] The present invention relates to a power relay assembly, and more specifically, for example, to a power relay assembly that can be used in an electric vehicle. Background technique [0002] Electric vehicle is a general term for vehicles that run on electricity. In general, electric vehicles are classified into electric vehicles (Electric Vehicle, EV) that run only on electricity, hybrid electric vehicles (Hybrid Electric Vehicle, HEV) that use electricity and fossil fuels, and the like. [0003] As far as electric vehicles are concerned, a power relay assembly (Power Relay Assembly) is arranged between the high-voltage battery and the electric motor. This power relay assembly functions to selectively supply power to the high-voltage battery. [0004] That is, the power relay assembly includes a main relay, a pre-charge relay, a pre-charge resistor, etc., and the above-mentioned components are electrically connected to each other through a bus bar as...
