Wireless charging technology expected to grow rapidly through 2020

Several companies are beginning to develop charging stations for electric cars that don't require cords or outlets. In the coming months, New York company HEVO, will combine forces with New York University to create wireless manhole charging stations, expected to be installed throughout Washington Square Park in early 2014. The technological developments could soon lead to increased demand for electric cars, meaning professional service centers may have to implement wireless charging stations and educate service professionals about electric car maintenance. 

According to Computerworld, one of the main reasons that more consumers have not adopted electric cars is the long refueling times. While a traditional car refuels in minutes, an electric car can take upwards of four hours for a 24 kilowatt-hour capacity battery, the battery size for a standard economy car. 

With new technologies being unrolled to charge cars more efficiently, may begin to gain popularity. To make a more efficient charging station, researchers are looking to wireless technology.

Wireless charging works through the creation of a magnetic field by alternating current in a transmitter coil, creating voltage in the receiver coil. The technology can be divided into two types: magnetic induction and magnetic resonance. The main difference is that induction charging requires that the car remain in contact with the charging surface. So far this is the most popular method. Duracell makes a charging pad that uses magnetic induction technology.

Several companies, including HEVO utilize magnetic resonance technology that allows the charging device to be several feet away from the energy source, creating a fully wireless technology. While the efficiency of the charge increases the closer the car is to the power source, HEVO's product is one step closer to an efficient charging station. 

The number of wireless charging stations worldwide is expected to increase by a factor of more than 100 from 2012 to 2020, IHS Automotive. The number of fast charging stations could be up to 199,000 locations in 2020.

What this means for professional service centers
As new charging technologies become available, professional service centers can implement them for customer convenience. In addition, wider adoption of electric cars might mean that automated service professionals might need to receive some new training. Some service professionals have worried that electric cars will mean the end of their profession, because EVs lack oil and spark plugs, among other things. In the long run, however, EVs will still need car service, just like a traditional vehicle.
