The invention concerns an energy storage system (12) for an electrified vehicle comprising a first battery module (20) and a second battery module (22) connected in series and providing a first voltage by connecting to a first positive output (24A) and to a first negative output (24B) of the first and second battery modules. The energy storage system comprises an energy storage module (30), providing a second voltage by connecting to its positive and negative output (32A, 32B), and four switches (40, 42, 44, 46) connecting positive and negative terminals (30A, 30B) of the energy storage module to positive and negative terminals (20A, 20B, 22A, 22B) of the first and second battery modules. By operating the four switches, the energy storage system can take one of three configurations: the energy storage module is connected in parallel with the first battery module, or connected in parallel with the second battery module, or isolated from the first and second battery modules.
