A structure of a battery disconnection unit for an electric vehicle is provided to reduce weight, improve assembling characteristics and operational reliability, and effectively support a plurality of high voltage relays which are relatively weighty. The structure comprises a first high voltage relay switching to a position for supplying DC power supplied from the battery to the inverter or to a position for interrupting the supply of the corresponding DC power; a second high voltage relay switching to a position for supplying DC power supplied from the charger to the battery or to a position for interrupting the supply of the corresponding DC power; a PCB including a printed wired circuit electrically connected to the second high voltage relay and providing a DC power supply path between the charger and the battery by having an input terminal connected to the charger and an output terminal connected to the battery; a substrate installed at an upper portion of the PCB to support the first and second high voltage relays; and a metal bracket supporting the PCB and the substrate at a lower side and operating as a heat sink radiating heat. |
