Abstract

A method for predicting an electric load imparted on each battery unit in an electric energy storage system comprising at least two battery units electrically connected in parallel to each other. The method comprises establishing a battery parameter set, the battery parameter set comprising at least the following values for each battery unit in the electric energy storage system: an internal ohmic resistance value indicative of the internal ohmic resistance of the battery unit and an open circuit voltage value indicative of the open circuit voltage of the battery unit, using an electric load level indicative of a total electric energy storage system load, and using the electric load level and the battery parameter set for predicting the imparted load on each battery unit in the electric energy storage system.
