In his remarks at the IEEE-PELS (Power Electronics Society) meeting in Korea, Momentum Dynamics Corporation’s CEO Andy Daga said he believes that 25 kW wireless chargers will be the norm for all EVs within 5 years, with commercialization beginning next year (2016). Momentum Dynamics is developing high-power inductive (wireless) chargers for electric vehicles.
Most PEV models currently on the market charge at 3.3 or 6.6 kW. Notable exceptions are Tesla (10 kW), the Volkswagen e-Golf (7.2 kW), the Mercedes-Benz B-Class electric drive (10 kW) and the BMW i3 (7.4 kW). (Data from ChargePoint).
The key to advancing the rate of adoption of electric vehicles (EVs) is linked to the way they are charged, Daga said. All EVs must be connected to the power grid, and according to Daga, “the impact of wireless charging is to fully automate the charging experience and relegate it to an unnoticed background function. This will make the experience of ‘fueling’ far better than pumping gasoline into a conventional gasoline vehicle. The most important benefit will be EV driving range extension. This is because automatic operation enables more frequent charging, and more frequent charging is the best way to increase driving range.”
Daga said the potential scale of the EV market is so large that the way people charge vehicles in the future needs to be fast and automatic, and cannot be accomplished in residential garages.
There isn’t enough power available on residential streets, and the fact is, most people do not have a garage. The concurrence of mandates and regional market growth make it clear that EV sales will increase, but we must recognize the corresponding need for rapid automatic charging with a ubiquitous network of chargers.—Andy Daga
