1. A method of charging at least one supercapacitor comprising steps of:

  • bypassing the current flowing in said supercapacitor so that, when the voltage at the terminals of said supercapacitor reaches a predetermined value, constituting a threshold voltage, the bypass current assumes a maximum value constituting a nominal bypass current, monitoring of a charging current of said supercapacitor as a function of the voltage at the terminals of said supercapacitor by a voltage detector logic function, wherein said voltage detector logic function comprises an optimization function, capable of changing from an activated state to a deactivated state when the voltage at the terminals of said supercapacitor exceeds a first predefined voltage greater than the threshold voltage and then capable of returning to the activated state when said voltage at the terminals of said supercapacitor falls below a second predefined voltage less than or equal to said first predefined voltage.
