More than a century ago, Nikola Tesla used electromagnetic energy to transfer power over an “air gap” between two coils, known as wireless, or inductive charging.
Audi claims a charging efficiency of more than 90 percent, meaning that less than 10 percent of the power sent to the charger is lost in the process of topping off the battery. Fully charged, the car — which is not due in the United States until next year — is expected to be able to travel about 30 miles on electricity alone, Audi said.
“A car sits for between 90 to 95 percent of its life,” Jesse Schneider, who heads a wireless task force for the Society of Automotive Engineers said. “If you can take advantage of the time it doesn’t move with a wireless-equipped parking space at home, where the customer doesn’t have to plug in but just park, then it changes the whole dynamic of the electric vehicle.”
