MODULE FOR LARGE SCALE ENERGY STORAGE

A module () for use in an energy storage system is provided, including a first terminal () and a second terminal (); a supercapacitor branch () including an arrangement () of one or more supercapacitors (), and a resistive bypass branch () including at least a first bypass switch () and a resistance () connected in series. The supercapacitor branch and the resistive bypass branch are connected in parallel between the first terminal and the second terminal. The module may further include a direct bypass branch () having a second bypass switch (), the direct bypass branch being also connected in parallel with the supercapacitor branch () between the first and second terminals. A control method of such a module and an energy storage system including several such modules, are also provided.
