Electrically driven auxiliary drive system and method for its preparation

A system and method for operating a power take-off system (100) aboard hybrid and electric vehicles and systems are disclosed. The auxiliary drive system (100) includes an energy storage device (116) for providing electrical energy and at least one electric drive system (108) which is electrically connected to the energy storage device (116) to receive the electric power, wherein each of the electrical drive systems (108) is adapted to convert the electrical energy into a desired mechanical energy. The auxiliary drive system (100) also includes at least one secondary output shaft (110) which is mechanically connected to a respective one of the electrical drive systems (108) and which is driven by the mechanical energy to output mechanical power or mechanical power, said mechanical power or energy of each of the power take-off shafts (110) can be adjusted independently of the mechanical power or the energy of the other power take-off shafts and / or controlled and / or regulated..
