Abstract

In a method for estimating a voltage of a battery a given battery model (BM) is provided, wherein the given battery model (BM) is a single particle model. A C-rate of the battery is determined. The battery model (BM) is adapted based on the C-rate. The voltage of the battery is estimated by means of the adapted battery model (BM).
