Abstract
The present invention relates to a supercapacitor balancing method including bypassing the current flowing in the supercapacitor from a predetermined threshold voltage at the terminals of the supercapacitor, the bypass current being a function of the voltage at the terminals of the supercapacitor and increasing continuously as a function of the voltage. The method is characterized in that the bypass current increases between the threshold voltage, for which the bypass current constitutes a minimum bypass current, and a reference voltage, for which the bypass current constitutes a nominal bypass current, and in that the difference between the reference voltage and the threshold voltage is less than 200 mV and the ratio between the nominal bypass current and the minimum bypass current is greater than 100.
