EV Charging Stations Go Wireless!

One of the biggest developments to come out of the world of electric vehicle charging station technology is a new crop of wireless charging systems soon to hit the market.

If a new partnership between Delphi Automotive and WiTricity works out, electric vehicle owners may soon be able to charge their cars simply by pulling up to a parking spot.

Whereas most EV charging stations to date have involved plug-in technology, this new system involves no cables or cords; it’s embedded in a parking lot or placed on a parking garage floor, and after drivers park over the system it transmits energy wirelessly to their vehicle to charge it.

According to the designers at WiTricity, the wireless charging stations can transfer 3,000 watts through to the parked vehicles above them, about the same as a plug-in charging station. 

A startup in London, HaloIPT, has already launched successfully in the UK a similar wireless charging station that is suitable for all vehicles - including scooters, electric cars, and electric bikes

Known as the Inductive Power Transfer System, allows a car fitted with a simple integrated receiver pad to be charged automatically when parked or driven on roads with HaloIPT’s special charging pads beneath their surface. This IPT method could give new meaning to the phrase "electric highway" by enabling charging technology to be directly embedded into the roads we drive on.
