Swedish automaker Volvo just announced that it’s working on a wireless inductive charger for electric vehicles. The charging pad is able to wireless charge any EV that parks above it using an electromagnetic field, and so far tests have yielded promising results.

“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 of Electric Propulsion System at Volvo Car Group. He added, “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.”

Volvo’s inductive charging system uses an electromagnetic field instead of a cord to transfer energy from a power source to a battery.

An induction coil in a charging base station creates the alternating electromagnetic field, and a second induction coil in the EV converts the field back into electrical energy that charges the battery. The technology is generally used in household appliances such as electric toothbrushes, and it could give EVs a big boost in accessibility. “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.

Volvo conducted their tests in Belgium, where a Volvo C30 Electric was charged 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.

The tests are part of Volvo’s strategic co-operation with Siemens to develop electric drive and charging technology for electric vehicles.
