WAVE - Wireless electric vehicle charging



Pads placed in the road could provide a solution to the 'elephant-in-the-room' problem currently afflicting electric vehicles.

Induction pads which allow the transfer of electrical energy are being tested on buses by engineers in the Netherlands and the US and by spring 2013, Milton Keynes in the UK.

Besides the obvious benefits, lighter vehicle weight from needing fewer heavy and cumbersome batteries, is a real boost to performance. 

Here's how Proov of the Netherlands describe their system...............
The solution of Proov with induction charging locations ensures that the buses never come to be without power all day and used for scheduling. The recharge can also be saved on the purchase of expensive batteries in the bus and the batteries last longer. We call it "unplugged e-mobility '
Other advantages of unplugged e-mobility are:
· Ease (no cables) 
· Security (no cables on the road, no contact with electricity) · high energy efficiency · Possibility of opportunity charging (when an opportunity arises)

How does induction charging work?
The bus arrives at the electrical box. There is situated a steel plate (the induction loop) in the ground. The communication on the bus indicates the electrical box through the bus above the steel plate. At that time, the current to the electrical box steel plate in the ground.The bus is also a steel plate (induction adapter). This would drain at the time when the bus is stopped to the ground. The plate in the bush and the plate in the ground up to each other.Because of the flow of the electrical box to the plate in the ground, it creates a magnetic field. This is passed on to the plate in the bus. And in the bus, the magnetic field is converted into current for the battery."
