Abstract

A method for detecting charging current curves for electric vehicles at charging stations. In the method, a charging current curve is captured at a charging station, and the charging current curve is stored together with a vehicle identification of the charging vehicle. For each respective vehicle identification, a charging current curve at a plurality of charging stations is stored, and for the respective vehicle identification, a present charging current curve can be compared with the stored charging current curves at the plurality of charging stations. In the event of a deviation of the present charging current curve from the stored charging current curves at the plurality of charging stations which is greater than a threshold, a signal is output.
