A method for estimating or predicting an internal battery state of at least one battery unit within an electric energy storage system, such as in a vehicle. The method includes obtaining operational data of the electric energy storage system relating to operating conditions of the electric energy storage system, feeding the obtained operational data to a non-linear state observer adapted to estimate and/or predict the internal battery state of the at least one battery unit in a series of time steps, such that an observer error of the non-linear state observer converges towards zero, or towards a value close to zero, based on at least the obtained operational data, estimating or predicting the internal battery state using the non-linear state observer.
