An electric drive system includes energy storage system (ESS), a power conversion system, and an alternating cumin (AC) traction system. The ESS provides or receives electric power. The ESS includes a first energy storage unit and a second energy storage unit. The power conversion system is electrically coupled to the ESS for converting an input power to an output power. The AC traction system is electrically coupled to the power conversion system for converting the output power of the power convention system to mechanical torques. The AC traction system includes a first AC drive device and a second AC drive device. An energy management system (EMS) is in electrical communication with the ESS, the AC traction system, and the power conversion system for providing control signals.

The present disclosure relates to a longitudinal guidance device for a motor vehicle with an electric drive machine, having a control unit, which can be coupled to the drive machine in order to actuate a drive torque, and a boost switch, which can be coupled to the control unit in order to request an additional drive torque, wherein the control unit is designed to actuate a higher drive torque while the boost switch is actuated until a maximum boost torque is reached and/or until the actuation of the boost switch ends.

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.
