Abstract
A system and a method of diagnosing a contactor through a sound sensor, which determines whether a contactor is erroneously operated based on a result of sensing a mechanical transition sound generated during an on/off operation of the contactor. The contactor diagnosis may be applied to a battery management system and may further include counting the number of transition operations of the contactor and/or may be used for diagnosing the life of the contactor.
