By strategically combining supercapacitors with BESS, their combined strengths can optimize battery performance. This study explores the role of supercapacitors in enhancing battery performance through both simulation and experimentation. The results obtained experimentally matched with simulated results.
Batteries provide high energy density. Supercapacitors have lower energy density than batteries, but high power density because they can be discharged almost instantaneously. The electrochemical processes in a battery take more time to deliver energy to a load. Both devices have features that fit specific energy storage needs (Figure 1).
Supercapacitor specific power is typically 10 to 100 times greater than for batteries and can reach values up to 15 kW/kg. Ragone charts relate energy to power and are a valuable tool for characterizing and visualizing energy storage components.
Among the two major energy storage devices (capacitors and batteries), electrochemical capacitors (known as ‘Supercapacitors’) play a crucial role in the storage and supply of conserved energy from various sustainable sources. The high power density and the ultra-high cyclic stability are the attractive characteristics of supercapacitors.
Furthermore, to effectively deploy supercapacitors as the supplementary energy storage system with batteries, different shortcomings of the supercapacitors must be effectively addressed. Supercapacitors lack better energy density and ultralong cyclic stability is a very important desirable property.
In such a case, supercapacitor-battery hybrid energy storage can handle the voltage and frequency stability by supplying the auxiliary power from the battery and transient power from the supercapacitor . In microgrids maintaining a DC bus requires less complexity than maintaining an AC bus because it is efficient and cost-effective.

Supercapacitors have advantages in applications where a large amount of power is needed for a relatively short time, where a very high number of charge/discharge cycles or a longer lifetime is required. Typical applications range from milliamp currents or milliwatts of power for up to a few minutes to several amps current or several hundred kilowatts power for much shorter periods. Supercapacitors do not support alternating current (AC) applications.
Supercapacitors suppress high-frequency oscillations, and the battery smooths the low-frequency oscillations; this increases the battery life [107]. Fig. 11 illustrates the …
