Highway Charging While Driving

Every few years one of these crop up and every time they fade into obscurity.

This I like. Glad I also reserved F150.

Just had to come to the Cybertruck forum and throw a jab, eh?

This will be great for when Samurai Goroh cuts you off on Big Blue and slams you into the barrier, but you know you will need to recharge to catch up to him in Mute City.

Next, contact-less curb charging (heard this before being built in Canada but there appears that there's no new development).

Highway Charging


A 1-mile stretch of road is being built in Detroit that can charge electric cars as they drive — if owners install a special receiver

• Electreon Wireless is building a mile-long stretch in Detroit that will charge electric cars as the drive on it.
• The company said the roadway will be fully functional by 2023 for EVs that install a special receiver.
• Charging infrastructure poses a major hurdle for electric-vehicle adoption.

A startup is building the first road in the US that will allow modified electric cars to charge as they drive...

I'm not sure that wireless charging in the roadway is going to benefit anybody very much any time soon. But at least Ford is getting ready to produce the Lightening. Musk is extremely poor with timelines. His noncommittal answer about probable 2023 for the CT means we still don't know when or if Tesla will produce the CT. The Preorder terms where very clear it didn't guarantee a sale price or production for the Cybertruck. If you ordered early on for the Lightening you could be enjoying it for a few years before the Cybertruck start to trickle out.

I‘m not sure what you mean. There is only one path for current flow into/out of the battery. If the power coming into the car Is greater than the power being used by the car, the surplus goes to the battery. If the power coming in is less than the power being used by the car, the battery will supplement the remaining amount needed. Not sure how you can charge and discharge a battery at the same time.

I’m currently using an iPad that is using power while I’m charging. My iPhone is aways on. Even when charging.

Does is just sound sexier to do this on roads? It seems like a way better use case would be to try this in stationary parking spaces (parking lots). I would love to have wireless charging in a garage some day. Roads are also extremely difficult to maintain and any work on the "charger" interrupts traffic. Not to mention all the other challenges purely around charge rate and the amount of surface you would need to cover to do any practical amount of charging.

The lost energy through the air constantly being transmitted just waiting to be "harvested" would have be over 98% losses. Extremely inefficient.

That’s the thing. The energy in the leakage flux is waiting be harvested but as there is no circuit for it to link it is returned to the capacitor during the next half cycle. Losses as low as 15% are claimed.

This article is so broken.

There is no difference between an 'electrical field' and a 'magnetic field'.

Time to get your physics book out Crissa!

That's misleading at best. We haven't really had vehicles capable of taking advantage of this yet.

I'd have to go digging, but I remember news reels from the 90s of electric cars that charged

We haven't have cars with batteries this big, no, but there have been murmurs of roads that charge for nearly 3 decades now. The price of a road that can do this is going to be substantially higher than good old asphalt and with minimal benefits.

The above comment about parking spaces that inductively charge is a way better application, but even then you're still better off with a hard wire for power delivery.

The concept has existed as long as cars have.

But this is the first time a significant amount of vehicles would have the potential to be compatible with such a system and not trapped on it.

Which is why it is not done that way.

What a bunch of Negative Nancies or is it Debbie Downers? You sound like ICE legacy folk saying EV won't work. Let them do their thing and if they find a way to make a buck and/or can charge while driving, then more power to them.
