Nowadays awareness of the importance of the environment and its preservation is continuously increasing. In the last decade, due to the stringent regulations implemented by the European Union on the emission of pollutants and Green House Gases, car manufacturers released numerous Electric Vehicles and Plug-in Hybrid Electric Vehicles. These vehicles necessitate an extensive public charging infrastructure to allow them to have appropriate everyday usability since the latter is limited by the battery range. Multiple papers indicate that European countries still lack an adequate charging infrastructure that should adapt to the electrification process. To mitigate this problem, this thesis focuses on the design and analysis of a small displacement Regenerative Internal Combustion Engine (RICE) to continuously recharge the battery even when the vehicle is stationary, thus potentially working for 24 hours 7 days a week.
