How Wireless EV Charging Works

[ericmark]

Where I work, they were proud to fit a public charging point, ⁣ but the personal door is right next to the charging point, and when one walks out with an arm full of gear, it is so easy not to see a looped charging cable.

To be fair, not a door that the public use, but should some be injured who would be blamed, the railways or the customer?

Maybe it's just me, but I find it rather sad that there seems to be so much obsession with 'attribution of blame' these days

Very carefully written article - a 90% increase in efficiency could be an increase from 1% to 1.9% so still crap.

In the real world it would be cheaper to put the wires in the air on poles and have a link from the car to the overhead wire - just as they used to have when I was a kid for the trolleybuses. Put the wire over the middle lane of motorways and we won't even see a difference in traffic flows - the middle lane will still be occupied by braindead morons.

I've linked to this video before, but I have no idea how things have progressed (or not) in the last three years...

...except that lorries won't be able to enter the middle lane...

Can't say for sure, but we drove along that motorway section in the summer this year, and there was not a truck in sight. I have a feeling that the money ran out.

So who should/should not use the middle lane of motorways, and why/why not?

They can, using battery.

Anybody who isn't overtaking a slower vehicle, or will need to in a short time. Because it reduces the capacity of the motorway. It's why signs saying "Don't hog the middle lane" are displayed. It's not just the middle lane, on 4-lane stretches plenty of drivers won't get out of the 3rd (from left) lane.

I can see that being a viable solution, at least for tall vehicles/trucks. It's still not a solution for cars, unless the EV cars are loaded onto electric trucks - one way to overcome the restricted range of EV's.

Not if it's got overhead wires low enough for cars, they won't.

Which would make it impossible for the trucks, to use those same roads, or even cross over them.

I thought we were talking about the middle lane of a motorway, but it's been a long day...

Assuming a three lane - It could work, in the outer lane, but there would have to be a complete ban on trucks ever entering the outer lane, plus any EV's in L2, would have to move to L3 and keep up, or not get charged.

I'm not sure that it's quite as simple as that .....

If, as is often the case, the traffic in the left-hand lane is already doing something like 70 mph, then your logic would mean that no-one could use (at a legal speed) any of the other 2 or 3 lanes (which would hardly improve "the capacity of the motorway ), wouldn't it?
