Abstract
A supercapacitors voltage balancing device () to be connected to a supercapacitor module () having N individual supercapacitors () connected in series, for optimizing the voltage of the individual supercapacitors in the module. The voltage balancing device comprising connecting means () for connecting said voltage balancing device () to said supercapacitor module (); a selector unit () for selectively connecting a group of P individual supercapacitors (), with P<N, to be subject in the same time to a voltage optimization processing; a voltage measuring unit () to determine the voltage of selected supercapacitor(s) (); a charge adjusting unit (), comprising voltage adjustment means for connecting in parallel to P individual supercapacitors () for adjusting in the same time the voltage of said P individual supercapacitors; a controller () for controlling the selector unit (), the voltage measuring unit () and the charge adjusting unit () and comprising evaluation means in order to determine which ones of the individual supercapacitors will be subject to the voltage optimization processing.
