Abstract

Computer system (100), computer-implemented method and computer program product are provided for indirect measurement of battery degradation of a particular electric vehicle (221). Parameter sets (200p) associated with completed charging runs (200) comprise: a charging level (220b-*), a vehicle range (220r-*), and a corresponding odometer reading (220o-*) or time point (220t-*). The vehicle range values (220r-*) are grouped by corresponding charging levels (220b-*) belonging to corresponding grouping intervals, such as predefined odometer reading intervals or time intervals in which the respective charging runs occurred. A maximum value (220mr-*) of the vehicle range related parameter obtained. For each charging level, a first mean/median (200rct-*) of the associated vehicle range is computed in each grouping interval. For each associated charging level (220b-*) in each grouping interval (GI*), the ratio of the first mean/median to the respective maximum value of vehicle range is computed, and an intermediate battery degradation value is determined by grouping interval for each charging level based on said ratios. For each grouping interval, a second mean/median of all intermediate battery degradation values across all charging levels is computed in the respective grouping interval (GI*) resulting in the battery degradation values (BDV*) for each grouping interval.
