Zusammenfassung:	Methods and systems are provided, including a method for an electric vehicle battery distribution among at least three motors. The method may comprise selecting a first drive path with at least first and second motors for an open-loop power allocation control, designating a second drive path with at least a third motor for an open-loop or a closed-loop power allocation control, determining a power allocation ratio of each motor relative to a total power; and operating the each motors with adjusted power limits based on the determined power allocation ratios.
