With the Government of India’s (GOI’s) renewed focus on sustainable development and improving the quality of air in the recent budget, cities in India have started integrating electric buses (e-buses) into their fleets. Around 1,000 e-buses are in service at the moment, and nearly 6,500 e-buses are expected to be deployed across the country by 2022. The high purchase cost of batteries, though, is proving to be a major deterrent to the large-scale adoption of e-buses.
