Abstract

An apparatus and a method for monitoring a breakdown of a battery system component are provided to more accurately determine whether a cooling fan for cooling a battery of an environment-friendly vehicle or a part related to the cooling fan fails. The method for monitoring a breakdown of a battery system component compulsorily driving, by a controller, the cooling fan and measuring the current temperature of the battery when the battery management system fails to receive a pulse width modulation PWM signal that represents an operation state of the cooling fan and a feedback signal (PFM) of the cooling fan from a cooling fan controller.
