  • Active cell balancing
    Patent number: 9153973
    Abstract: A battery cell balancing system includes N switching circuits connected to first terminals and second terminals of N battery cells, respectively, where N is an integer greater than one. A first transformer includes a first core and N sets of windings wound around the first core. The N sets of windings are connected to the N switching circuits, respectively. A first control module controls switching of the N switching circuits to reverse first connections between the first terminals and the second terminals of the N battery cells and the N sets of windings, respectively, at a first frequency to balance charge levels of the N battery cells.

  • Isolation monitoring system and method utilizing a variable emulated inductance
    Patent number: 8598897
    Abstract: A system for measuring leakage resistance between a high voltage (HV) system of a vehicle and a vehicle chassis includes an emulated inductance that is connected between the HV system and the vehicle chassis and that has an inductive reactance that substantially cancels a capacitive reactance between the HV system and the vehicle chassis. A signal source outputs one of an AC current signal and an AC voltage signal between the HV system and the vehicle chassis. A sensor measures one of an AC current response to the AC voltage signal between the HV system and the vehicle chassis and an AC voltage response to the AC current signal between the HV system and the vehicle chassis.
