Integrated Strategic and Operational Planning for a Fast-Charging Battery Electric Bus System

As an integral part of a multimodal transportation ecosystem, the public bus system provides an economical and sustainable travel mode that plays a key role in reducing traffic congestion and exhaust emissions. Conventional bus fleets, however, are mainly powered by diesel engines characterized by low energy efficiency, exhaust emissions, and oil dependence. Compared to diesel buses, battery electric buses (BEBs) have several advantages, including higher energy efficiency, zero tailpipe emissions, improved reliability, a lower maintenance burden, and the capability for using renewable energy sources, such as wind, solar, and water energies. Moreover, BEBs are easier to deploy and more flexible in their operation than trolley buses. Although BEBs have many advantages and have been adopted by a number of transit agencies, due to limitations in battery technology, they are disadvantaged by cumbersome and costly on-board batteries. Moreover, it takes very long time to recharge BEBs using either standard or slow-charging methods. The emerging fast-charging technology promises the potential to offset these drawbacks. With fast-charging technology, a BEB with a modest battery capacity can utilize the dwelling times between trips to quickly recharge its battery and maintain continuous operation. Fast-charging technology has been adopted by many BEB demonstration projects, and promising results have been report. In this project, the research team simultaneously considers and optimizes the battery and charger configurations of a fast-charging BEB system, as well as its recharging scheduling during operation. The team also explicitly consider the demand charges of high-power recharging activities of BEBs.
