    Abstract: A hybrid powertrain system includes an engine and an electric machine respectively connected to first and second drive axles, with the electric machine decoupled from the engine. The system includes a battery pack and a controller. The controller has slip integrators with a corresponding integrator value for a given one of the drive axles. The integrator values are indicative of an accumulated amount of drive wheel slip over a calibrated duration or window. The integrator values change responsive to axle torque and traction control status signal. The integrator values are added together to derive an integrator sum. Responsive to the integrator sum exceeding a calibrated integrator threshold, the controller executes a control action, including automatically executing a Weather Mode in which energy use of the battery pack is reserved for traction control/propulsion of the vehicle.

    Abstract: The concepts described herein provide a system and associated charging connector that is capable of offloading electric power stored in a rechargeable energy storage system (RESS) of an electrified vehicle to supply electric power to a stationary system, e.g., a residential dwelling or a business site, upon occurrence of a power outage in an electric power grid that supplies electric power to the stationary system. This includes the charging connector being capable of offloading electric power under conditions in which the RESS of the electrified vehicle is initially disconnected from the charging connector when the power outage occurs. This concept enables an electrified vehicle to supply electric power to a stationary system when connecting after a delay period subsequent to the power outage.
