    Abstract: A hybrid-electric vehicle and method of controlling a hybrid-vehicle is provided. The vehicle includes a traction battery, at least one electric-machine, and a controller. The controller is configured to alter a voltage between the battery and the electric-machine based on a measured voltage of the battery or the high voltage bus. In response to an indication that the measured voltage is faulty during a drive cycle, the controller instead alters the voltage between the battery and the electric machine based on a substituted battery voltage signal such that the electric-machine remains operable for the drive cycle.

    Abstract: Systems and methods provide an alternative high voltage cutoff technique for disconnecting a high voltage battery from an electrical network of a vehicle in the event of a fault condition. Embodiments include a vehicle system comprising an electrical bus and a battery module coupled to the electrical bus via a contactor and a disconnector. The vehicle system further includes a controller configured to switch the contactor to an open state, upon receiving a fault condition signal, and if the contactor failed to open, activating the disconnector to break electrical connection between the battery module and the electrical bus. In some embodiments, the fault condition signal is generated upon detecting a vehicular impact. In some embodiments, the disconnector is a pyrotechnic device powered by a vehicle battery included in the vehicle system.
