Method for determining a technical condition of an electrically powered motor vehicle and motor vehicle

The method involves detecting the operating parameters (T1,T2,n,I) of the drive motor (2) and/or of circuit arrangement (3) during operation of the motor car (1) by a computing unit (6) of motor car. The operating parameters of the parameter values are stored in the memory unit (7) of the motor car. The technical state is determined based on the stored parameter values. The data with the parameter values of communication device (8) of motor car are transmitted to computing device external to the motor car, and the physical condition of vehicle is determined by computing device. An independent claim is included for powered motor car.
