The gradual increase in carbon emission along with the greenhouse gases results in increased global warming due to the smoke emission from the IC engine vehicles has adversely degraded the environment quality and human health. The global data of 2018 show that road transport accounts for three quarters (74.5%) of the total emissions where passenger vehicles contribute 45.1% and trucks carrying freight contribute 29.4%. Different alternatives have been studied and developed for the reduction of such emissions from the transportation sector. The global world is transitioning towards cleaner means of transportation and it is high time for Nepal to focus on clean transportation technology. Almost 99.9% of the transportation sector of Nepal is dependent on petroleum and diesel-based fuels. In such a scenario, electric vehicles could be one of the alternatives. This paper studies the possibilities of the conversion of IC engine vehicles to battery electric vehicles in the transportation sector. An internal combustion engine Maruti Suzuki 800 car model is selected for conversion into BEV. The internal combustion engine and other related components are removed and replaced by the electric traction motor, battery, and other electrical components with the existing gearbox and transmission system. The components are selected as per the requirements based on the calculations. An electric motor is powered by a lead-acid battery and the electric motor transfers the power up to the wheels that propel the vehicle. A simple model MATLAB/Simulink is developed and tested virtually for analysis and improvement before the actual conversion process. Finally, the vehicle is successfully tested and run on the track without any technical problems. The overall project shows the technical feasibility, an adaptation of new technology, and technology transfer as well as the reuse of an old IC vehicle in the transportation sector in Nepal.
