“…The batteries of SC at the present stage have a capacity of thousands of farads with voltages from hundreds to thousands of volts. Fairly high figures for specific capacities of SC are achieved due to the internal resistance of the element smaller than 0.1 mOhm [1][2][3][4]. SC can operate at least 1 million cycles without degradation of electrical characteristics, which significantly exceeds the resources of well-known industrial AB designs.…”

“…Modern samples of SC have the specific energy seven times lower than that in lithium-ionic AB, while hundreds of times higher than the specific energy in the LC. Based on these features of SC, AB and LC, it is advisable to provide the established modes of electricity consumption by the load from AB, and at pulse consumption of significant power -to work with SC or LC [2,[9][10][11].…”

In this paper, energy processes in combined power supplies with supercapacitors (nonlinear capacitors) and linear capacitors at their charge from a non-ideal DC source, for which there is a rechargeable battery, have been analyzed. The energy characteristics of charge circuits in combined power supplies with supercapacitors and linear capacitors have been obtained. An analysis of the dependence of the energy difference accumulated in the supercapacitor and in the linear capacitor in the process of charge (from zero initial conditions to voltage U f = U n /n), on the variations of the parameter n, has been performed. The dependence of the energy ratio accumulated in the capacitors during the charge period on the value of the final voltage on the terminals of the capacitors has been investigated.
