volvo c30 wireless chaging test

Volvo completed what it called a "successful" study of wireless charging systems for electric vehicles by fully charging up an all-electric C30 in about two and a half hours.

The Swedish automaker used words like "comfortable," "effective" and "safe" to describe the inductive charging system. Such a process involves induction coils on both the station and the vehicle and uses electromagnetic waves to conduct the necessary electricity. Volvo is working with Siemens to develop electric-drive powertrains and hopes the study helps move the industry towards some sort of yet-to-be determined wireless-charging standard.

Other automakers are also looking at wireless charging as another way to get more people to gravitate towards plug-in vehicles. Toyota is working on a wireless charging system for its Prius Plug-in Hybrids, while Nissan's Infiniti division said last year that it aimed to make the first production model with a wireless charging system as standard equipment.

As for Volvo and its plug-ins, the company has been making the electric C30, albeit in limited numbers, since 2011. Volvo also started making its V60 plug-in diesel hybrid late last year and said at the time that it would produce between 4,000 and 6,000 cars for the 2014 model year.

Volvo Car Group completes successful study of cordless charging for electric cars

Volvo Car Group has been a partner in an advanced research project that has studied the possibilities of inductive charging for electric vehicles – and the results show that this technology for transferring energy via an electromagnetic field has a promising future.

"Inductive charging has great potential. Cordless technology is a comfortable and effective way to conveniently transfer energy. The study also indicates that it is safe," says Lennart Stegland, Vice President, Electric Propulsion System at Volvo Car Group, and adds "There is not yet any common standard for inductive charging. We will continue our research and evaluate the feasibility of the technology in our hybrid and electric car projects."

Cordless charging
Inductive charging uses an electromagnetic field instead of a cord to transfer energy between two objects. An induction coil creates an alternating electromagnetic field from a charging base station. A second induction coil in the portable device picks up power from the electromagnetic field and converts it back into an electrical energy that charges the battery. This technology is common in electrical home appliances such as electrical toothbrushes but is not yet commercially available to charge electric cars.

"With inductive charging, you simply position the car over a charging device and charging starts automatically. We believe that this is one of the factors that can increase the customer's acceptance of electrified vehicles," says Lennart Stegland.

Research in Flanders
The completed research project, which included inductive charging for cars and buses, was initiated by Flanders' Drive, the knowledge centre of the automotive industry in the Flanders region in Belgium. It featured a consortium of companies, including Volvo Car Group, Bombardier Transportation and the coachbuilder Van Hool. The project was partly funded by the Flemish government. Volvo Cars supplied the car for the inductive charging project: a Volvo C30 Electric with a power output of 89 kW (120 hp).

"The tests demonstrated that our Volvo C30 Electric can be fully charged without a power cable in app. 2.5 hours. In parallel with this, we have also conducted research into slow and regular charging together with Inverto, which was also a partner in the project," says Lennart Stegland.

Volvo Cars has focus on electrification
Volvo Cars' ambitious strategy for electrification has also resulted in the successful launch of the fast-selling Volvo V60 Plug-in Hybrid, which entered series production in 2012.

The company has initiated strategic co-operation with Siemens in order to develop electrical drive technology, power electronics and charging technology as well as the integration of these systems into electric vehicles.
