Abstract: An electric power system for a vehicle provided with a storage assembly comprising a first storage system with a number of electrochemical cells connected to one another in series and/or in parallel and a second storage system arranged in series to the first system and with a number of electrochemical cells connected to one another in series and/or in parallel; wherein the storage assembly is designed to supply power with a dual voltage; and wherein the electric power system comprises, furthermore, a DC/DC converter, which is designed to transfer the electric charge from the second storage system to the first storage system, and vice versa, and integrated in a BMS device for the management of said storage assembly, which is designed to carry out the balancing of the electrochemical cells of the second storage system and to estimate the state of charge and the state of health of the two storage systems.
