摘要：The present provides a leakage detection circuit for an electric vehicle, and soon, capable of calculating a leakage resistance. The leakage detection circuit for an

electric vehicle detects a current I(t) that flows in leakage resistances Rand Rwhen oneleakage detection switch SWis closed at tand the other leakage detection switch SWisopened, and detects a current I(t) when the switch SWis opened at tand the switch SWisclosed. In addition, the circuit detects voltages V(t, t) and V(t, t) of portions where theseleakage detection resistances Rare connected. A combined value Rof the leakageresistances is calculated by a leakage calculator based on the following equation 34
