The present invention relates to a method for enabling dynamic evaluation of performance of a battery energy store. The method comprises measuring (2) real-time parameters (V, I, T) of a battery energy store (1), estimating (3) a state of charge (SOC) for the battery energy store, the estimation being based on the measured real-time parameters and off-line data (4) of the energy store, identification (3) of R-C parameters for an equivalent circuit model (ECM) of the battery energy store, the identification being based on the measured real-time parameters, updating (5) a look-up table with the identified R-C parameters for different operating conditions, and simulating (5) performance of the battery energy store based on two or more operating conditions. A system, a marine vessel and a computer program product thereof are also presented.
