Special Session #2: Electric (Battery, Fuel Cell and Hybrid) Buses - VPPC 2021

Co-chair: Paulo G. Pereirinha, Polytechnic of Coimbra and INESC Coimbra (Coimbra/Portugal)
Co-chair: Andoni Saez de Ibarra, IKERLAN Technology Research Centre (Basque Country/Spain)

Call For Papers

The road transport decarbonization’s challenge is seen to be spearheaded by road public transport, due to its advantageous characteristics. However, fossil fuel public transportation contributes significantly to city pollution, and there is a growing search for proper solutions to these issues. Among the available alternative technologies, several studies have pointed out hybrid and full-electric buses as very valuable options, however, for decarbonizing the most demanding routes, fuel cell buses are gaining popularity. This is leading to an increasing demand from governments and cities followed by a growing effort from most bus manufacturers to offer competitive and suitable electric buses. Proposals using different battery chemistries, mostly based on lithium but not only, with different voltage levels, battery capacities and ranges, focused on night slow charge or fast and/or ultrafast opportunistic charge, cable or pantograph conducted or wireless charging systems, hybridization of the battery with energy storage systems as ultra-capacitors or hydrogen fuel cells, with the required energy management system, fleet management proposals and total cost of ownership analysis to evaluate the viability of the integration are appearing at an ever-increasing pace.
This special session is focused on addressing these questions, especially for full-electric buses (EB), of all sizes, but including also plug-in hybrid electric buses (PHEB), Fuel Cell Buses (FCB) and Hybrid Electric Buses (HEB).
Topics of interest include, for full electric and plug-in hybrid electric buses, but are not limited to:

  • Power-train system simulation and modeling
  • EB, FCB and PHEB with multi-storage systems design and management
  • Energy storage systems integration and management
  • Total cost of ownership studies
  • Fleet management
  • Chargers location and scheduling
  • Real cases of electric buses exploitation experiences and defies
  • Bus tests and measurements
  • Cities public transport electrification analysis
  • Retrofitting or upgrade of powertrain and storage systems
  • Urban mobility studies
  • Components simulation and modeling
  • Power converter topologies (Traction Power and Distribution, Overhead Contact
  • Systems, and Other Feeding Systems)
  • Powertrain design (power electronics, regenerative braking and motor)
  • Motors, predictive control and application
  • System level reliability
  • Environmental and System Requirements
  • Functional safety for battery management system and battery packs
  • Charging systems components
  • Standardization for Standardization for electric EB and PHEB



Paulo G. Pereirinha Bio: Paulo G. Pereirinha received his PhD Degree in Electrical Engineering from the University of Coimbra, Coimbra, Portugal.
