  Over the past decade, most of the metropolitan cities across the world have
been witnessing a degrading trend in air quality index. Exhaust emission data
observations show that promotion of public transport could be a potential way
out of this gridlock. Due to environmental concerns, numerous public transport
authorities harbor a great interest in introducing zero emission electric
buses. A shift from conventional diesel buses to electric buses comes with
several benefits in terms of reduction in local pollution, noise, and fuel
consumption. This paper proposes the relevant vehicle technologies, powertrain,
and charging systems, which, in combination, provides a comprehensive
methodology to design an Electric Bus that can be deployed in metropolitan
cities to mitigate emission concerns.
