A Quantification Analysis on Potential Use of Recuperated Regenerative Braking Energy from NYCT Subways into Charging Electric Buses
… (MTA) is one of the biggest consumers of electricity in east coast of the United States. According to a report published by Dayton T. Brown in 2013, MTA consumes approximately 2150 GWh electrical energy per year for traction power, where the New York City Transit (NYCT) alone is a consumer …

The effects of drive cycle accessory load and degree of hybridization on fuel economy and emissions for hybrid electric buses
Hybrid Electric Vehicles (HEVs) have gained much attention in recent years. This is mainly due to rising fuel prices and increasing environmental awareness. By implementing electricity as one of the power sources, a HEV can not only reduce fuel consumption but can also decrease tailpipe emissions. …

Power Infrastructure Requirements for Road Transport Electrification
… of this PhD thesis. A widespread penetration of electric vehicles (EVs) across a large proportion of road transport demand is needed to realise the benefits of an electrified transport sector. However, this is dependent on overcoming significant barriers. This study performs a systematic analysis …
