Battery management systems and methods for operation of same are provided. A first switchable resistance may be connected between a cell stack positive end and ground. A second switchable resistance may be connected between a cell stack negative end and ground. The switches for each resistance may be alternately opened and closed, with comparison of the resulting currents through each resistance being indicative of a location of isolation leakage current within a battery system cell stack, and/or the magnitude of isolation leakage current. Currents through the first and/or second switchable resistances may also be indicative of Y capacitance. The first and second switchable resistances may further be used to reduce energy stored by Y capacitance.
