Scandinavia unveils its first line of inductive charging electric buses

The Swedish city of Södertälje has been the latest to run an electric-hybrid bus equipped with Bombardier’s inductive or wireless charging technology, PRIMOVE, behind the German cities of Berlin, Braunschweig and Mannheim, and the Belgian city of Bruges.

This was the first project of its kind in Scandinavia and is the result of a group of projects led by Scania, which has been exploring alternative mobility solutions in an effort to make sustainable and ecological mobility a reality in the Swedish city.

Inductive charging makes it possible to recharge the batteries without cables simply by parking on a loading platform buried in the ground thanks to the IPT transfer technology between an in-vehicle integrated device and another buried in the pavement, explains CIRCE, Center for Research on Energy Resources and Consumption of the University of Zaragoza.

In addition, among its advantages is that the recharge is completely safe despite the high power levels, since electromagnetic emissions are kept at levels well below the limits allowed. The user does not have to get out of the car to plug it in and can have a deviation of 30% with respect to its emitter, so the power transfer is very comfortable. As for security, this type of recharges can be integrated anywhere and are almost invisible, so they are protected against vandalism and weather conditions.

Inductive recharging and electric mobility

With Scania and Vattenfall we have found two partners who are committed to the development of sustainable mobility with innovative technology,” says Jérémie Desjardins, business leader of PRIMOVE. “Together, we are looking forward to reducing public transport emissions in the most convenient way, as well as bringing the wireless recharging to the Swedish transport market.”

To promote the entry into service of the bus, the last stop on route 755 of Södertälje has become a recharging station that will allow the vehicle to quickly recharge its batteries every time it stops there. With up to 200 kW of power, in just six to seven minutes the charging station will be able to supply enough power so that the bus can service the entire 10 km long route. The station is owned by Swedish energy supplier Vattenfall while a second charging station has also been installed at the Scania Technical Center in Södertälje.

Bombardier’s wireless-powered vehicles have covered more than 450,000 km since the first BOMBARDIER PRIMOVE electric bus entered passenger service in Braunschweig, Germany, in March 2014, with very good reception from both passengers and drivers, the company says in a statement.

In addition, in Nanjing, China, trams have been running on PRIMOVE’s lightweight and long-lasting batteries for more than two years. Since March 2015, Bombardier has also collaborated with automakers for the serial development of the PRIMOVE inductive charging solution for use in electric cars.

With PRIMOVE’s broad and flexible portfolio of technological solutions, Bombardier offers a unique comprehensive service for true electric mobility.
