Title: APPARATUS AND METHOD FOR SELECTING EARTH CAPACITOR
Abstract:
The present invention discloses a technique that enables an optimal capacitor to be efficiently selected when connecting an earth of a circuit board and a vehicle chassis through a capacitor in order to externally discharge noise generated in the circuit board. A device for selecting an earth capacitor according to the present invention is a device for selecting an earth capacitor connected between a vehicle chasis and an earth of a circuit board included in a battery pack, and includes: a checking module which checks an earth position on the circuit board; a selection module which selects a reference position on the circuit board on the basis of the earth position checked by the checking module; a calculation module which calculates, as a reference distance, the distance from the reference position selected by the selection module to the nearest earth position; a computation module which computes a reference frequency by using the reference distance calculated by the calculation module; and a choosing module which chooses a recommended capacitor on the basis of the reference frequency computed by the computation module.
