Even in these early days of battery electric vehicles, charging cables are already proving to be potential problems. They can be heavy and unwieldly, they are trip hazards, and if it hasn’t already happened, drivers are bound to drive off without first unplugging, or just leaving the cable laying on the ground.
Is wireless charging a practical alternative?
A new technology developed by a company called WiTricity makes wireless charging possible for all types of electric vehicles, including trucks. It allows wireless energy transfer at power levels from milliwatts to kilowatts over distances up to several meters and through materials such as metal, concrete and pavement.
