ELECTRIC VEHICLE WITH FAST-CHARGE FUNCTION

摘要

A vehicle includes an electric drive motor for driving the vehicle, an electrochemical accumulator for storing and providing electric energy for the drive motor, the accumulator being configured to only take up a charging power which is smaller than a predetermined maximal power value, an electric auxiliary storage for storing and providing electric energy for the drive motor, the auxiliary storage being configured to take up a charging power during charging which is greater than the maximal power value; a charging device for receiving energy from a vehicle-external charging station as a power pulse which has an amplitude greater that the maximal power value and to store the received energy in the auxiliary storage; and a coupling circuit coupling the auxiliary storage with the accumulator and configured to transmit the energy from the auxiliary storage into the accumulator with a charging power which is smaller than the maximal power value.
