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: A climate control system for vehicles includes an internal combustion engine that may be coupled to selectively power a first motor generator, and an air conditioning compressor that may be selectively powered by one or both of the first motor generator and a second motor generator, or by the internal combustion engine. The system may include a rechargeable battery, and a vehicle controller having a vehicle state circuit structured to determine a vehicle operating condition value and a state-of-charge value of the rechargeable battery, and a coupling determination circuit structured to provide an internal combustion engine-first motor generator coupling command in response to the vehicle operating condition value and the state-of-charge value. In response to the internal combustion engine-first motor generator coupling command being provided as coupled, the internal combustion engine may power the first motor generator.
