Wireless vs wired DC fast charging efficiency test

Efficient wireless charging is on the way for EVs: [LINK] [VIDEO] No cables or charging posts mean lower maintenance costs and tidier parking spaces.

> How does that work for people who live in cities? With curbside charging, and wireless charging will be convenient once that's rolled out. No cables, just park over the charging plate. It's not like wireless phone charging. It's very efficient: [LINK] [LINK] [VIDEO]

> If there only was a system that could automatically disconnect Or just use wireless charging, then there are no cables. Wireless charging for EVs can be efficient: [VIDEO] And wired charging is not as efficient as you might think: [LINK]

Wireless charging can be surprisingly efficient. You should check out this video where wireless charging beats wired charging in end to end efficiency: [VIDEO] In that case it’s probably more due to a particularly inefficient DC fast charger. (It’s been a long time since I watched it so I might not remember the details right.) In the end it doesn’t have to be exactly as efficient as wired charging, and probably never will be for a good implementation of a wired charger. It only has to be so close that you don’t care about the difference. I don’t think the inverse square law is very relevant on these scales. Electromagnetic radiation can be focused.

> There's zero chance this will make it into a production vehicle Wireless charging is in production. Here's one example: [LINK] Wireless charging can be as efficient as wired charging: [VIDEO] [LINK]
