A computer system (210) for controlling an energy storage system (ESS, 200) with heterogenous battery packs (110) is provided. The system is configured to, using a processing circuitry (220): obtain pack-specific minimum and maximum allowed operating voltages (Vi,lim) for each battery pack; determine joint ESS-specific minimum and maximum voltage limits satisfying each of the respective pack-specific minimum and maximum allowed operating voltages for all of the battery packs; obtain actual state of charge, SoC, values (SOCi) for each battery pack; determine rescaled SoC values ( SOCi∗) by scaling the actual SoC value for a battery pack to a range defined by an estimated SoC value of the battery pack at the ESS-specific minimum and maximum voltage limits, and control the ESS using the rescaled SoC values for the battery packs. A corresponding ESS, vehicle, computerimplemented method and computer program product/storage medium are also provided.
