Abstract
An apparatus for sensing leakage current of a battery includes a current sensing resistance installed on a current detection path of positive and negative terminals of a battery; a DC (Direct Current) voltage applying unit for inducing a potential difference with an opposite polarity to the current detection path through the current sensing resistance; and a leakage current determining unit for sensing a magnitude of current flowing through the current sensing resistance according to the induced potential difference on the current detection path, and determining based on the sensed magnitude of current whether leakage current occurs.
