Fast-Charging Busses

news-transport-oct17-ABBbigbus.jpg

Problem: At the moment, many public transit bus fleets are still utilizing fossil-fuel powered vehicles. While many systems are transitioning to hybrid models, there are not many 100% emissions-free bus lines around the world.

Solution: A bus that is 100% electric, wire-free, and able to be re-charged at stations that are equipped with charging points.

  • New electric busses by Swiss manufacturer HESS will use flash-charging technology that will enable batteries mounted on bus roofs to be charged in 20 seconds (while passengers enter and exit) with 600-kilowatts at stations where charging ports are installed.
  • Busses are hooked to the charge point in less than 1 second. Charging stations at the end of line terminals will provide full charges to the busses before their next route.
  • The city of Nantes, France is adopting this technology for a full route (Line 4).
  • Electric busses are not only emissions free, they also produce much less noise than conventional busses.

Stakeholders:

  • municipal transportation authorities
  • transit riders
  • communities along bus transit routes

First 3 Steps:

  • Document the performance of Line 4 in Nantes for a period of time after the new bus rollout (vehicles and stations)
  • Make improvements and fixes where necessary for both vehicles and infrastructure
  • Market the bus system to transit authorities that have aging bus fleets and are looking to upgrade to sustainable models

One thought on “Fast-Charging Busses

  1. This is conceptually really “smart” but I wonder about what they claim to be able to do vs. what can actually be done. It’s logical to see this sort of quick charging take hold on the public transport lines and it really improves the efficiency of energy use but it’s not a straight forward fossil-fuel free solution until the energy comes from that source. Perhaps in France, with all the nuclear, it makes this ring true but if you put this in Wisconsin it won’t for all you’re doing is displacing the fossil-fuel from the source point at the vehicle to the power generation location. In my analysis there are many instances where the electrification of the transport sector makes things worse for CO2 emissions. Then again, local air quality will always go up so it depends on the objective of the smart city – local solution, regional, or global.

    Thanks for sharing, cool tech and more to come I’m sure.
