Andrew Daga, CEO of Momentum Dynamics, sees the future of EVs in wireless charging.

At the Institute of Electrical and Electronics Engineers (IEEE)- Power Electronics Society (PELS) Conference in Daejeon, Republic of Korea, Daga said that the right solution is 25 kW wireless charging.

He believes that this will be the norm for all EVs within 5 years! And commercialization will begin next year.

"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.” He went on to say, “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 scale of this 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.” Daga showed data that point to increasingly stringent anti-pollution mandates correlated to the three fastest growing automotive markets – China, North America, and Western Europe. “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.”

Sounds great, but do we already have a worldwide standard of wireless charging? And what will be the cost of a 25 kW wireless charging system? To charge at 25 kW, besides the wireless charging device, you need to have 25 kW on-board charger instead of 3.3 or 6.6 kW, which translates to more costs.
