- Electric vehicles (EVs) has been in the rise in popularity, and as a result, opportunities for alternative power systems research have expanded. Traditional EVs consist of lithium-ion battery for the power source as they can provide long vehicle range at a relatively low cost. [1] Supercapacitors (SCs) are energy storage devices with the high-power density and low energy density, which means it can deliver and handle a high amount of energy in a short period, but energy deliverance is significantly shorter compared to batteries. As a result, supercapacitors cannot be the primary power source in electric vehicles as a long vehicle driving range is essential. However, supercapacitors are currently being studied for a hybrid electric vehicle powertrain. Compare to lithium-ion batteries, supercapacitors have higher charge/discharge efficiency, charge acceptance, and cycle life [2]. Using a supercapacitor as an ancillary device has been shown to reduce power loads on batteries.
