A Cost-Competitiveness Analysis of Charging Infrastructure for Electric Bus Operations
This study investigates the cost competitiveness of different types of charging infrastructure, including charging stations, charging lanes (via charging-while-driving technologies) and battery swapping stations, for supporting an electric public transit system. To this end, we first establish mathematical models to investigate the optimal deployment of various charging facilities along the transit line and determine the optimal sizes of the electric bus fleet and their batteries to minimize the total infrastructure and fleet cost while guaranteeing the service frequency and satisfying charging need of the transit system. We then conduct an empirical analysis utilizing available real-world data. Results suggest that the service frequency, circulation length, and operating speed of a transit system may have a great impact on the cost competitiveness of different charging infrastructure; and charging lanes enabled by the currently available inductive wireless charging technology are cost competitive for most of the existing bus rapid transit corridors
- Present cost-competitiveness analyses of different types of charging infrastructure for electric bus operations
- Explore factors that will have a great impact on the cost competitiveness of different charging infrastructure
- Identify the key to making charging lanes more competitive for transit systems
