Electric vehicles (EVs) can help reduce our carbon footprint by decreasing carbon dioxide emissions. Increasing prices of fossil fuels as well as their rapid depletion has invited research and development in the field of EV. The primary source of energy currently are lithium-ion batteries. The drawbacks of Li-ion batteries include their explosiveness and non-reusability. Supercapacitors are hence seen as the potential replacement of Li-ion batteries offering high-power density and extended life, thus also reducing e-waste. There is only a need for monitoring and automating the battery system used in order to prevent damage to the batteries, and hence increase the efficiency. Herein, a small simulation model of electric vehicle is designed and comparison is carried out between Li-ion battery and supercapacitor performance in this model.
