METHOD FOR RECOGNIZING MANIPULATIONS IN THE HIGH-VOLTAGE NETWORK OF ELECTRIC AND/OR HYBRID VEHICLES

摘要

A method for recognizing manipulations in the high-voltage network of electric or hybrid vehicles is described. The disclosed method is characterized by the following steps: First, the total current and/or the total voltage in the high-voltage battery and at one or more points in the external high-voltage network of the vehicle are measured; then a difference between the measured values for the high-voltage battery and the measured values for the external high-voltage network is determined. Finally, a manipulation is recognized when the difference exceeds a predefined threshold value.
