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.

    提出一种用于预报电动车辆(10.1、10.2、...、10.n)的车队(10)的车辆电池(14.1、14.2、...、14.n)的剩余使用寿命的计算机实现方法。所述方法的特征在于,(100)在所述电动车辆(10.1、10.2、...、10.n)的运行中,测量所述车辆电池(14.1、14.2、...、14.n)的特征参量并且传送给服务器(12);(200)确定特定的车辆电池(14.1、14.2、...、14.n)的剩余使用寿命在位于过去的时间点未超过预定的极限值的条件概率;和根据条件概率预报所述车队(10)的车辆电池(14.1、14.2、...、14.n)的剩余使用寿命。
