Plug-in hybrid bus of Green Propulsion with 37 km e-range
Walloon propulsion company Green Propulsion is presenting a new plug-in hybrid bus with 37 km of pure electric range, offering 59% to 70% of fuel saving compared to a diesel bus.
After 40.000 kilometres of tests on three types of trips, the second hybrid bus from Green Propulsion is ready to go into production. The Hybribus is a plug-in hybrid vehicle capable of driving 37 km in full electric mode in one charge. On the three study scenarios (urban, extra-urban and combined), it presented a fuel consumption cut by 59 % (extra-urban) to 70% (urban) compared to a classic diesel bus.
TEC hybrid busses
Plug-in hybrid buses aren’t new on our roads. Indeed, the TEC is already running Volvo plug-in hybrid busses in the cities of Namur and Charleroi. 12 buses are already on service and 90 will be delivered shortly.
The Volvo bus only offers a 7 kilometre full electric range, but there is a reason for that. “For buses, the most important part is the number of people that you transport. If you add 2.000 of 3.000 kg of batteries, you get less space for people, which means more buses and drivers”, explains the hybrid bus sales manager for Volvo Bus Belgium Eric De Roy. “The average length of a trip is 10 km. So 7 km of e-range means 70% of the trip that is electric. Charging takes 3 to 6 minutes”, he adds.
CEO of Green Propulsion Laurent Minguet estimates that Volvo’s offer isn’t sufficient and that his company can offer more. “These buses can’t cross the city purely on electricity and they need specific charging points”, he explains. The propulsion specialist based in Liège offers a system that can be charged before the journey and that doesn’t need a ‘refill’ along the way. It uses its battery capacity to the maximum and its electric motor is 30% more efficient than a classic diesel engine.
Public authority incentive
According to the company’s CEO, public authorities should ask for more electric range from their urban plug-in hybrid buses. Furthermore, this would incite manufacturers to call on companies such as Green Propulsion. “There aren’t 10 companies in Europe capable to offer this kind of technology”, adds Laurent Minguet.
