Abstract:
1. Electrical energy buffering system, comprising an energy source for delivering electrical energy, an energy buffer for buffering electrical energy delivered from the energy source, the energy buffer comprising a plurality of supercapacitors, and control logic for controlling the operation of the energy buffer by selectively switching the supercapacitors, wherein the plurality of supercapacitors are switchably connected in parallel to each other in a circuit comprising the energy source and an electrical power output, and the control logic comprises a buffer monitor for monitoring a parameter corresponding to the charge or discharge state, respectively, of each of the supercapacitors and is adapted to sequentially switch on single supercapacitors or groups of supercapacitors of the plurality of supercapacitors, responsive to the detection of a first predetermined charge or discharge state, respectively, and to switch off said single supercapacitors or groups of supercapacitors of the plurality of supercapacitors, responsive to the detection of a second predetermined charge or discharge state, respectively.
