<p>The present invention relates to a relay control system and a control method thereof and, more specifically, to a relay control system comprising; a battery pack having anode and cathode terminals; a first main relay in which both ends are connected between the anode terminal of the battery pack and a first node which is one end of a load; a second main relay in which both ends are connected between the cathode terminal of the battery pack and a second node which is the other end of the load; a first pre-charge unit which is connected to the second main relay in parallel and forms a first pre-charge resistance and a first pre-charge relay with a series circuit; a second pre-charge unit which is connected to the first main relay in parallel and forms a second pre-charge resistance and a second pre-charge relay with a series circuit; and a calculation amplifier in which both ends are connected to the first and second node. The calculation amplifier outputs a voltage applied from the load through an output terminal.</p> |
