FIELD: electricity.
SUBSTANCE: invention refers to the field of electric engineering and to a method of electrochemical capacitors operation. The suggested method includes connection of a capacitor to a current source, its charge up to the preset voltage, cassation of charge, and discharge, at that the temperature of the capacitor is measured preliminarily and against this temperature the maximum operating voltage of the charge excluding gas release is defined, and a calculation is made of the maximum charging voltage Umax, which is limited as per the formula Umax=k·t+b, where k and b are coefficients determined experimentally and depending on peculiarities of the capacitor design, t is the temperature, at that current of floating charge is calculated to measure coefficients k and b.
EFFECT: invention allows increase in the capacitor power and service life at operational safety ensured by optimisation of its charging conditions, which is recognised as a technical result of the invention.
