Volvo Cars tests wireless charging in Gothenburg taxis

Testing over three years in taxi operation in Gothenburg for wireless charging with over 40 kW. The "Green City Zone" initiative aims to transform the city into a real-world lab. Technology by Momentum Dynamics.

The Swedish Geely subsidiary Volvo Cars, in cooperation with partners, has initiated wireless charging for electric cars. In Gothenburg, a small fleet of fully electric Volvo XC40 Recharge taxis is entering pilot operation. The electric vehicles employed by Cabonline, the largest taxi company in Scandinavia, can be charged without cables at selected stations. The three-year trial phase is one of many projects under Gothenburg's "Green City Zone" initiative, which aims to accelerate the development of sustainable technology, as outlined by the manufacturer. Parts of the city are being transformed into a test laboratory.

"Gothenburg's Green City Zone allows us to test new technology in a real environment and evaluate its future, widespread introduction," says Mats Moberg, Head of Research and Development at Volvo Cars.

The testing of new charging processes together with selected partners is a good way to evaluate alternative charging options for our future electric vehicles, Moberg further states.

Fast Charging Without Getting Out

The fully electric Volvo taxis are in operation for more than twelve hours per day and cover around 100,000 kilometers annually. Thus, the electric cars are also undergoing the first endurance test in a commercial use scenario. They are charged at stations from Momentum Dynamics, a leading provider of wireless electric charging systems. As soon as a compatible electric vehicle parks over a charging station embedded in the ground, the charging process begins automatically. For optimal alignment, the manufacturer uses its 360-degree camera system. Via a charging pad, the station sends energy to the receiver in the car. The electric SUV is wirelessly supplied with more than 40 kW of power, making the charging speed about four times as fast as with a privately used 11-kW wall box and almost as fast as with wired 50-kW DC fast chargers.

Close Collaboration with Several Partners

In addition to Cabonline and Momentum Dynamics, the project also involves Swedish retailers Volvo Bil and Volvo Car Retail, which are owned by Volvo, Swedish energy provider Vattenfall with its InCharge charging network, the municipal energy company Göteborg Energi, and the "Business Region Göteborg," a municipal economic development agency in the city of Gothenburg. The Swedish manufacturer has been part of Gothenburg's "Green City Zone" initiative, which aims for zero-emission road traffic by 2030, since last year. Using a real city as a test area allows for faster development of new technologies and services in the areas of electrification, shared mobility, autonomous driving, connectivity, and safety, believe the Swedes.
