Abstract: A vehicle includes an inverter configured to power an external device. The vehicle further includes a controller programmed to cause the inverter to output a voltage at a steady-state amplitude and a steady-state frequency and, responsive to detecting an inrush current event in progress that is caused by the external device, operate the inverter to reduce the voltage to prevent an overcurrent. The controller is programmed to identify the type of load connected and return the voltage to the steady-state amplitude and steady-state frequency based on the type of load.

Abstract: A method includes measuring an impedance of a shunt as a function of frequency and converting the impedance to an admittance in a time domain. The method further includes connecting the shunt in a circuit and measuring voltage data across the shunt over a predetermined interval. The method includes outputting a signal indicative of a current through the shunt derived from the voltage data convolved with the admittance. The method may be implemented in a controller configured to interface with the shunt.

Abstract: An electrified vehicle and associated inverter configured for powering two different types of external loads include first and second phase/line legs combined with a first neutral leg coupled to a vehicle chassis, and a second floating neutral leg that is not coupled to the vehicle chassis. The first/second phase legs and first neutral leg are coupled to a first receptacle configured to receive a corresponding plug to power a first load, such as a power tool or accessory. The first/second phase legs and the second neutral leg are coupled to a second receptacle configured to receive a corresponding plug to power a second load, such as a home or building having an earth grounding electrode. The inverter may include an isolation transformer between the loads and the traction battery, and/or may be configured to provide single phase, split-phase, or three-phase power for either or both of the neutral connections.

Abstract: A vehicle includes a power-electronics converter and an electrical outlet in electric communication with the power-electronics converter and configured to power external loads. The vehicle includes at least one electrical outlet including at least a first socket configured to power a first category of external loads and a second socket configured to power a second category of external loads. The vehicle is configured to only power one of the first and second loads at a time. This may be accomplished using physical features or electronically.

Abstract: The methods and systems for correcting for an inductive load when testing high voltages devices are described. A high voltages device is a device under test (DUT) in a double-pulse test, which may require the inductive load. The method can include in a low current, high voltage time period, estimating an inductor current contribution range after a turn on of the device-under-test connected to an inductive load with an air core inductor. The method subtracts the estimated inductor current contribution from a device-under-test collector current to output a corrected collector current. This allows the double pulse test to be conducted with an air-core inductor. Vehicles can use the DUT in traction power applications.
