Disclosed are a device and method to control a parallel relay for applying and blocking power from a battery to an inverter. The relay control device of a battery includes: a first relay unit which switches a connection between a first terminal of a battery unit and a first terminal of an inverter unit including a capacitor, and has two or more relays connected in parallel; a first switch which is connected to the first relay unit in parallel in order to prevent the arc and damage of the first relay unit; a second relay unit which switches a connection between a second terminal of the battery unit and a second terminal of the inverter unit, and has two or more relays connected in parallel; a second switch which is connected to the second relay unit in parallel to prevent the arc and damage of the second relay unit; and a control unit which controls to turn on and off the first relay unit, the first switch, the second relay unit, and the second switch in order to apply and block power from the battery unit to the inverter unit. The present invention is able to prevent secondary accidents.
