Beschreibung
Zusammenfassung:	Systems and methods are provided for modularizing a system. Parallel power systems having electronically isolated high voltage systems facilitate modulization. A control system is provided that optimizes the distribution of a power demand and/or a torque request so as to keep the efficiency, durability, drivability and/or safety of the system within an optimum range. In some cases, the distribution of power is uneven, so as to extend the battery life, while in other cases, the power draw on battery systems are kept equal and constant so as to properly manage the state of charge of the parallel power systems. In still other cases, the chosen power distribution keeps the power demand and/or torque request between minimum and maximum levels/capacity, and the power distribution avoids on/off of an individual power system.
