In India, the usage of two-wheelers for daily activities is high. Thus, consumption of petrol is on the rise. If the spending of a country is considered then 80−90% spending is done to pay import bills on petroleum products, which are counted as the country’s expenditure. The final result is a hike in the price of petrol and hence rising inflation. India is now the fourth largest emitter of greenhouse gases in the world. The transport sector accounts for 13% of India’s related CO2 emission which is mainly high in the traffic. Deployment of electric vehicles in large numbers is hindered by a variety of barriers. Scaling up electric vehicle’s penetration and realizing their full potential would be required. For this situation, now one of the solutions is retrofitting of existing scooters into hybrid electric scooters. Instead of turning existing petrol vehicles into scrap, this can be utilized as hybrid electric vehicles, as nowadays, focus of government is on “National Electric Mobility Mission Plan 2020” (NEMMP 2020). Thus, the aim of our project is to enhance the capacity of cities to improve mobility with lower CO2 emission. It can be a valuable contribution to achieve NEMMP 2020. The system proposes a solution by retrofitting existing scooters into hybrid electric which runs on Internal Combustion Engine. Here, by using scooter that has 80cc petrol combustion engine. The front wheel is replaced by an electric hub motor. It becomes a 2-wheel drive scooter with the hub motor driving the front wheel and conventional engine powering the rear wheel. Our main aim is to increase mobility and to improve the performance efficiency of existing vehicles. System proposes three switching modes here; Economy mode (Propulsion using motor only), power drive mode (propulsion using engine only) and hybrid mode.
