20 kW Induction SystemFlanders' Drive, Volvo, Van Hool, Bombardier and others are partnering to work on creating an induction charging system that could allow electric vehicles to be charge quickly and conveniently. Just park over a buried plate and log in the system (unlike in the image above, it'll probably be done by wireless identification), and voilà! Charging a battery pack of the size fitted to the Volvo C30 Electric(24 kWh), which Volvo will use for testing, is expected to take about an hour and twenty minutes, if the battery is entirely discharged.
In inductive charging, a charging plate is buried in the ground--e.g., 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.
Such systems could be installed in home driveways, inside garages, in public parkings, etc. It could make EVs more convenient than gasoline cars since you'd never have to stop at a
gas charging station.
