Abstract
A method and apparatus for determining coolant leakage in a vehicular propulsion system battery. An AC isolation resistance test is used to determine whether an isolation fault has occurred within the battery, but can also determine the capacitance of the circuit or system, which can further determine the coolant leakage levels of the vehicular propulsion system battery. This eliminates having an additional device to measure the coolant leakage.
