INDUCTIVE CHARGING FOR ELECTRIC CARS.
Volvo Car Corporation is participating in an inductive charging project with Flanders' Drive and others.
What's the agenda?
Volvo Car Corporation is developing systems and methods that need neither power sockets nor charging cables. With inductive charging, energy is transferred wirelessly to the car's battery via a charging plate buried in the road surface.

Wireless energy transfer
In inductive charging, a charging plate is buried in the ground, for instance in the driveway at home where the car is parked. The charging plate consists of a coil that generates a magnetic field. When the car is parked above the plate, energy from the plate is transferred without physical contact to the car's inductive pick-up. The energy that is transferred is alternating current. This is then converted into direct current in the car's built-in voltage converter, which in turn charges the car's battery pack.
Testing on Volvo C30:
Charging a battery pack of the size fitted to the Volvo C30 Electric, 24 kWh, is expected to take about an hour and twenty minutes, if the battery is entirely discharged. The charging system to be evaluated is dimensioned for 20 kW.
