Sweden Today sees the launch of Scandinavia's first electric bus service with wireless terminus charging. The electric hybrid bus will be used in regular service in Södertälje, south of Stockholm, and will be fast charged discreetly using Vattenfall's charging station.

The bus route was officially opened by Environment Minister Karolina Skog and Vattenfall's CEO, Magnus Hall. Vattenfall is responsible for installation and operation of the charging station, which will supply the electric hybrid bus with 100% electricity from wind power.

With wireless terminus charging, the bus parks over a charging segment concealed in the road and charging takes place automatically through the use of induction technology. The same principle is used for instance in induction hobs and electric toothbrushes. Seven minutes of charging is sufficient to sustain the electric hybrid bus over the entire ten kilometre route.

Following its inauguration on 7 December, the route will be monitored for a year as part of a joint R&D project between the bus manufacturer Scania, Vattenfall, the public transport operator SL, the Royal Institute of Technology (KTH) and the Municipality of Södertälje. The project is partly funded by the Swedish Energy Agency.

"The collaboration is a concrete example of Vattenfall's strategy being put into practice. Further electrification of the transport sector is a key factor in our efforts to achieve a climate-neutral Sweden. A hundred years ago Vattenfall electrified Sweden and the railways, and now we're electrifying road transport," says Vattenfall's CEO, Magnus Hall.

It's the first time that an electric hybrid bus used in regular service in Scandinavia has been supplied with wireless terminus charging. The charging station is located at the terminus of route 755 in Södertälje next to the Tom Tits Experiment science centre.

Reduction in emissions of CO2
"Vattenfall wholeheartedly supports the objective of reducing emissions from the transport sector, and offering customer-focused charging solutions for electric buses is part of Vattenfall's plan for the future," says Hall.

Amongst other things, the project will demonstrate the significant potential for reducing emissions of CO2 and improvements in energy efficiency in the transport sector. When the electric hybrid bus is powered by electricity from wind power, CO2 emissions decrease by around 98% and the improvement in energy efficiency is around 70% compared with a conventional diesel bus.

"The experience gained from the project will be important for the public transport of the future. It allows us both to test the reliability of the technology and to find out what the various stakeholders think. Electric buses with fast charging significantly reduce emissions and make traffic in urban environments quieter," says Johan Tollin, Vattenfall's representative in the project, who is responsible for research and development around e-mobility at Vattenfall.


  • The project in Södertälje, which involves putting an electric hybrid bus charged using induction technology into regular service, is a first for Scandinavia. The bus is powered by electricity over the entire route and can also travel over longer distances using biodiesel.

  • The electric hybrid bus will run on existing route 755 between the commuter train station Södertälje Syd and Tom Tits Experiment Science Centre, a round trip of some 10 kilometres.

  • The bus will be charged wirelessly from a charger concealed in the road at the terminus to a receiver installed under the floor of the bus. The installed capacity of the charger is 200 kW.

  • Wireless terminus charging is a joint venture between Scania, Södertälje municipality, KTH, SL and Vattenfall. The Swedish Energy Agency has invested SEK 8.5 million in the project.

  • Sweden aims to have a fossil-free vehicle fleet by 2030. The electrification of public transport is a key part of this strategy.
