Abstract
The present invention relates to a method of and a system for charging at least one supercapacitor that is particularly suitable for balancing supercapacitors. The method includes a step ( ) of bypassing the current flowing in the supercapacitor so that, when the voltage (V) at the terminals of said supercapacitor reaches a threshold voltage (V ), the bypass current (I ) assumes a maximum value, which method is characterized in that it includes a step ( ) of monitoring of the charging current (I ) of said supercapacitor as a function of the voltage (V) at the terminals of said supercapacitor by a voltage detector logic function (F ) able to change from an activated state to a deactivated state when the voltage (V) at the terminals of said supercapacitor exceeds a first predefined voltage (V ) greater than the threshold voltage (V ) and then to return to the activated state when said voltage (V) at the terminals of said supercapacitor falls below a second predefined voltage (V ) less than or equal to said first predefined voltage (V ).
