Only a small percentage of the cars in our country run on batteries instead of gasoline. As a result, there is a fuel shortage and environmental degradation as well. Nearly all emerging nations struggle with a serious issues like air pollution. The automotive industry must discover an alternate fuel source due to the scarcity of fossil fuels and the inadequacy of such fuels. Automobiles produce more CO2 than they should, which makes it necessary to develop new technologies like hybrid electric vehicles (HEV). With the help of this study, we hope to create a system that can power a motor using both batteries and an internal combustion engine that burns gasoline. Regenerative braking is utilized in this system. This system's energy regeneration could result in lower emissions, shorter charging times, and reduced fuel use. The article combines the mechanical and electrical systems industries to demonstrate the improvement in fuel economy. A smart energy management system with solar charging is used in this work.
