Scania to test wireless charging for electric city bus
Scania has become the first company in Sweden to test a wirelessly charged electric-hybrid city bus. The bus will start operating on the streets of Södertälje, Sweden, in June 2016 as part of a research project into sustainable vehicle technology.
Scania is undertaking intensive research into various types of electrification technologies that could replace or complement combustion engines. Induction is among the options being investigated and would involve vehicles wirelessly recharging their batteries via electrified roads.
Now, for the first time in Sweden, Scania and the Stockholm based Royal Institute of Technology (KTH) plan to test the technology in real-life conditions. The project will be run through their jointly operated Integrated Transport Laboratory research centre.
Swedish Energy Agency will provide 9.8 MSEK for the project’s realisation. Other stakeholders include Södertälje Municipality, Stockholm County Council and Tom Tits, the tech-oriented museum for children and youths.
As part of the field tests, a Scania citybus with an electric hybrid powertrain will go into daily operation in Södertälje in June 2016. At one of the bus stops there will be a charging station where the vehicle will be able to refill wirelessly from the road surface enough energy for a complete journey in just six-seven minutes.
“The main purpose of the field test is to evaluate the technology in real-life conditions,” says Nils-Gunnar Vågstedt, Head of Scania’s Hybrid System Development Department. “There is enormous potential in the switch from combustion engines to electrification. The field test in Södertälje is the first step towards entirely electrified roads where electric vehicles take up energy from the road surface.”
To build an infrastructure and convert bus fleets to vehicles that run exclusively on electricity will provide many advantages for a city. With a fleet of 2,000 buses, the city can save up to 50 million litres of fuel each year. This means the fuel costs decrease by up to 90 percent.
Apart from induction, Scania’s research and development department is looking at different technology options, including the take-up of energy from overhead electrical wires or from rails.
