摘要： The present disclosure provides a method of selectively charging or discharging a system with multiple battery packs connected in parallel when at least one of the battery packs has a significantly different voltage or states of charge (SOCs) than the other battery packs. The method includes charging or discharging the battery pack(s) with a voltage or state of charge (SOC) farthest from a target value until the voltage(s) or SOC(s) is within a range of another battery pack at which point the battery packs may be connected and charging or discharging can resume for the set of connected packs. This process is repeated until all the battery packs are at a predetermined minimum or maximum voltage or SOC threshold. The present disclosure also provides a method for selectively operating and charging at least one of a plurality of battery packs depending on the respective states of the battery packs.

摘要： Controls for improved performance of a vehicle equipped with start-stop control logic are disclosed. Deviation from nominal engine start-stop control logic for the internal combustion engine occurs when a predetermined mission related type of stop event will occur or is occurring that is different from other stop event types that are controlled by the nominal engine start-stop control logic. At least one of a location and a payload associated with the mission related stop event type is provided as an input to the controller before the vehicle arrives at the stop event so that operating parameters of the vehicle are controlled accordingly.

摘要： A system for a non-hybrid vehicle is provided. The system includes an electromagnetic device structured to couple to an engine and generate AC electrical power from the engine. The system also includes an AC-to-DC inverter structured to receive and change the AC electrical power to regulated DC electrical power. Additionally, the system includes an electrical path coupled to the AC-to-DC inverter and configured to provide the regulated DC electrical power directly to an electrically-powered accessory at or above 28 volts DC.
