Abstract: 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.

Abstract: Mild hybrid powertrain controls and apparatuses, methods and systems including the same are disclosed. One exemplary embodiment is a mild-hybrid system comprising an engine, an electrical machine, power electronics, an energy storage system, and an electrical load. The system includes a controller structured to receive an electrical machine power command based upon a power allocation to the electrical machine, process the electrical machine power command with feedforward controls structured to compensate for an inaccuracy associated with the power electronics, process the electrical machine power command with proportional integral (PI) controls structured to compensate for a power loss associated with one or more electrical loads, provide a compensated machine power command based upon the processing with the feedforward controls and the processing with the PI controls, and output the compensated machine power command to control the electrical machine.
