Abstract: Various disclosed embodiments include illustrative control units, systems, and methods. In an illustrative embodiment, a control unit includes a processor and computer-readable media that stores computer-executable instructions. The instructions cause the processor to establish a reserve level for a battery of a first device. The reserve level provides sufficient electrical power to enable the device to achieve a function. The instructions further cause the processor to enable the battery to function as a power supply configured to provide electrical power for a second device external to the first device responsive to a power level of the battery exceeding the reserve level and to disable use of the battery as the power supply for the second device responsive to the power level of the battery being below the reserve level.
Abstract: A method for predicting power capability of a battery pack in a system includes determining an open-circuit voltage of the battery pack via a controller, calculating pack resistance using measured voltage and current during a charge or discharge event, and calculating a maximum current of the pack using the open-circuit voltage and internal resistance. The method includes selecting the lower of an absolute value of each of the calculated maximum discharge current and predetermined current limit, calculating the discharge power capability of the battery pack using the selected lower absolute value, and controlling a state of the system using the calculated power capability. The method also controls the charging current and parameters during a DC fast-charging operation. A system includes the battery pack, electric machine, and controller. The system may be a vehicle having an electric powertrain, with an electric machine powered by the battery pack.
Abstract: A diagnostic system for a vehicle electrical system having a first and second diagnostic application is provided. The first diagnostic application commands a high side driver circuit and a low side driver circuit to transition a contactor to an open operational position when a first difference value is greater than a first threshold difference value indicating that at least one of the first and second analog multiplexers is malfunctioning. The second diagnostic application commanding the high side driver circuit and the low side driver circuit to transition the contactor to the open operational position when a second difference value is greater than the first threshold difference value indicating that at least one of the first and second analog multiplexers is malfunctioning.

Abstract: A system and method for decreasing partial discharge between adjacent conductive plates includes suspending a plurality of particles in the space between adjacent plates of a magnetic coil. The plurality of particles are generally uniformly dispersed in the space and allow for increased partial discharge inception voltages. Such a construction allows the coil to operate at elevated driving voltages with reduced partial discharge between adjacent plates.

Abstract: A repair device for fixing a malfunctioning shunt across a failed filament in a light bulb in a group of series-connected miniature decorative bulbs includes a high-voltage pulse generator producing one or more pulses of a magnitude greater than the standard AC power line voltage. A connector receives the pulses from the pulse generator and supplies them to the group of series-connected miniature decorative bulbs. The pulse generator may be a piezoelectric pulse generator, a battery-powered electronic pulse generator, and/or an AC-powered electrical pulse generator.

Abstract: A measuring system particularly suitably usable with an apparatus having a plurality of electron emitting sources, for measuring the characteristics of the electron emitting sources is disclosed. In the measuring system, the electron emitting sources are driven so that they emit electron flows of predetermined and different frequencies. The emitted electron flows are collected and, thereafter, only those signals having components corresponding to the predetermined frequencies are extracted. Based on the extracted signals, the characteristics of the electron emitting sources are measured at the same time and independently of each other.
