The absence of electrification has prevented the development of commercialized electric cars (EVs) from progressing more quickly. When it comes to lowering emissions in passenger road transportation, electric vehicles that are powered by low-emission electricity are a crucial choice. The advent of electric vehicles will unavoidably increase the interplay between power generation and mobility. The demand for electricity from electric automobiles becomes a significant issue in the energy system and affects the operation of power plants and grid infrastructure as the prevalence of electric cars increases. The selected objective of electric car demand management may involve the following smart charging strategies: lowering grid limitations, optimizing the use of renewable energy production to lower CO2 emissions, or decreasing emissions by switching electricity generating from coal and gasoline. The environmentally friendly smart electric car body panel that is presented in this study is thought of as an energy generator that uses solar power and vehicle deceleration and storage before being released to satisfy the demand of the auxiliary power system. In addition to reducing the vehicle’s speed from to 25 km/h and producing 1.43 kW of renewable energy from solar power, the smart body panel is anticipated to save 10% of the vehicle’s propulsive force by reducing the weight of the vehicle by 15%.
