    Abstract: A vehicle includes an electric machine, an engine, and stator. The electric machine has a magnetic armature and an electromagnetic armature. The electromagnetic armature is secured to a wheel and has an electrical circuit that includes primary and secondary coils. The engine is configured to rotate the magnetic armature to induce current in the circuit via the primary coils. The stator has tertiary coils that are configured to transfer power to the electromagnetic armature via the secondary coils to drive the wheel.

    Abstract: A system includes an isolation detection unit (IDU) having a first leakage detection circuit and being configured to determine an isolation characteristic for a voltage bus; and a circuit detection and response unit (CDRU) configured to determine whether the first leakage detection circuit is coupled to a second leakage detection circuit by a common ground. The CDRU can use a change in isolation characteristic of the voltage bus to determine whether a second detection circuit is coupled, and can characterize a coupled circuit. IDU operation and fault detection thresholds can be altered to mitigate confounding effects caused by simultaneous operation of both circuits. A system can be disposed at an electric vehicle to detect coupling of a detection circuit at a charging apparatus, or disposed at a charging apparatus to detect coupling of a leakage detection circuit at an electric vehicle.
