“…The general equivalent circuit of an electric doublelayer capacitor is indicated with a capacitance C and a resistance R connected in series. This is a good approximation of any real capacitor if long-term processes are excluded from 2) 3) and 4) . The terminal voltage of the capacitors v and the charge/discharge current of the capacitors i can be expressed by the following equation:…”

“…A three-branch model, which connects three branches of RC serial connections in parallel, has been studied [20] and is called the Zubieta model; it includes a capacitor that represents voltage dependency. Another type of model comprises three RC serial connections with two serial switches that operate according to time-variant responses [16].…”

For several years now, electric vehicles (EVs) have been expected to become widely available in the micro-mobility field. However, the insufficiency of such vehicles' battery-charging and discharging performance has limited their practical use. A hybrid energy storage system, which comprises a capacitor and battery, is a promising solution to this problem; however, to apply model-based designs, which are indispensable to embedded systems, such as the electronic control units used in EVs, a simple and accurate capacitor model is required. Within this framework, a lithium-ion capacitor (LIC) model is proposed, and its charging and discharging performances are evaluated against an actual LIC. The model corresponds accurately to the actual LIC, and the results indicate that the proposed LIC model will work well when used with Model-Based Design (MBD).

“…Recently, characteristics of EDLC 1 have been improved in many studies;2–8 however, some characteristics still need enhancement, such as the specific energy density and capacitance. EDLC utilizes the double layer formed at the interface between the nanoporous carbonaceous electrode and the nonaqueous electrolyte solution.…”

In this research, spatio‐temporal profiles of positive and negative charges in an electric double layer capacitor (EDLC) which consists of activated carbon, treated by plasma discharges were measured. The plasma type was a high frequency glow discharge and the sample of activated carbon is set in the center of glow discharge. Optimal conditions for plasma surface treatment of activated carbon was examined from 0 to 60 min at 150 °C in nitrogen gas. As a result, nitrogen atom was doped onto the surface layer of the activated carbon. In addition, electron spectroscopy for chemical analysis (ESCA) spectra of nitrogen in the activated carbon was examined. By etching the surface layer of carbon electrode exposed to the plasma, the doped nitrogen atom penetrated about 3 nm of the surface layer of carbon electrode after 60 min of plasma surface treatment.
