1. An apparatus for detecting a fault in a battery system, the apparatus comprising:

  • a voltage detector configured to receive a voltage signal from the battery system and to digitize the voltage signal to generate voltage data;

    a discrete wavelet transformer configured to receive the voltage data and to perform a discrete wavelet transformation of the voltage data to generate transformation data;

    a statistical processor configured to receive the transformation data and to process the transformation data to generate statistical data, the statistical data comprising an average value of the transformation data; and

    a fault diagnosing unit configured to detect the fault in the battery system based on the statistical data and to transmit a fault signal when the fault is detected.
