  • Isolation resistance measurement of power system in vehicle
    Patent number: 11254215
    Abstract: This disclosure describes techniques for separately determining isolation resistances from nodes of a power system of an electric vehicle (EV) to a chassis of the EV. Processing circuitry may determine a first isolation resistance between a first node of the power system in the EV and a chassis of the EV, determine a second isolation resistance between a second node of the power system in the EV and the chassis of the EV, determine that the first isolation resistance or the second isolation resistance is less than a threshold resistance, and output information based on the determination that the first isolation resistance or the second isolation resistance is less than the threshold resistance.
