EVS29: Wireless in-wheel motors could lead to EVs without batteries
Let's get all future-y on this one.
Takeuchi says that these in-wheel motors have "a lot of merit" to make EVs more efficient. One of the benefits of the wireless power transfer is that you don't have to worry about the wires breaking. But more exciting is the idea that you could let induction charging pads in the roads power the wheels directly, bypassing any sort of on-board energy storage. Since Takeuchi is starting work at Toyota soon, the next batch of student is going to build a test track on campus to keep advancing the technology.
As of last year, the wireless motors could transmit power through about 20 cm of empty air at 95 percent efficiency and can get the small prototype vehicle (which you can see in the video above) up to around 45 miles per hour.
