The invention relates to a computer-implemented method for predicting the remaining service life of vehicle batteries (14.1, 14.2,..., 14.n) of a fleet (10) of electric vehicles (10.1, 10.2,..., 10. N). The method is characterized in that during operation of the electric vehicle (10.1, 10.2,..., 10. N), a characteristic variable of the vehicle battery (14.1, 14.2,..., 14.n) is measured (100) and transmitted to the server (12); (200) determining a conditional probability that the remaining service life of the specific vehicle battery (14.1, 14.2,..., 14.n) does not exceed a predetermined limit value at a past time point; and forecasting the remaining service life of the vehicle batteries (14.1, 14.2,..., 14.n) of the fleet (10) as a function of the conditional probability.
