Abstract
A method for increasing the power during an acceleration process of an electrically operated motor vehicle with at least one electrical machine includes detecting a storage request by at least one control unit and initiating an increase in the rotation speed of a rotor of the electrical machine of the motor by the control unit before an acceleration request, so that kinetic energy is stored in the rotor of the electrical machine. The acceleration request is detected by the control unit and the energy stored in the rotor of the electrical machine is released during the acceleration process.

A method for increasing the power during an acceleration process of an electrically operated motor vehicle having at least one electrical machine, the method comprising the steps of:
- detecting a storage request by at least one control unit,
- initiating an increase of the speed of a rotor of the electrical machine of the motor vehicle by the control unit before an acceleration request and storing kinetic energy in the rotor of the electrical machine, and
- detecting the acceleration request by the control unit and releasing energy stored in the rotor of the electrical machine is released during the acceleration process;
- wherein the storage of the kinetic energy in the rotor of the electrical machine is initiated automatically or manually;
- wherein the storage of the kinetic energy in the rotor is carried out upon detection of an upcoming acceleration process by the drive power of the electrical machine and/or during a running deceleration process by storing the deceleration energy.
