The invention relates to a method for reconfiguring electrical energy storage packs of an electrical energy storage system (2) of a vehicle (1), the method comprising: determining (S102) a state of health of each of the electrical energy storage packs (BP1-BP4) of the vehicle; detecting (S104) at least one malfunctioning electrical energy storage pack (BP4) of the electrical energy storage system; determining (S106) an uncertainty measure for each of the determined state of health's; concluding (S108) to replace the electrical energy storage packs (BP3) having state of health lower than a minimum state of health, and electrical energy storage packs that are concluded to be malfunctioning, evaluating (S110) the determined state of health's and the corresponding uncertainties for maintained electrical energy storage packs and a set of replacement electrical energy storage packs to find a combination of maintained electrical energy storage packs and replacement electrical energy storage packs that fulfil energy and power requirements for the vehicle taking the uncertainties in state of health into account; determining (S112) a new configuration of the electrical energy storage system including the combination of maintained electrical energy storage packs and replacement electrical energy storage packs, providing (S114) a signal indicating an arrangement of the electrical energy storage packs according to the new configuration, once electrical energy storage pack replacement is performed, determining (S116) a load sharing factor (α) indicative of a load distribution between the electrical energy storage packs of the new configuration, and if the load sharing factor fulfils a predetermined condition, performing (S118) a reconfiguration of the electrical energy storage pack to more equally distribute the load across the electrical energy storage packs.
