Induction charging spaces are improving

[caseys]

So TeslaBjorn did a vid with a company in Norway which have retrofitted induction charging into an iPace :

55kw charging wirelessly. That seems good. Maybe this will solve the “no off street parking” residential problem? Also easier to build into works car parks and also helps the problems of awkwardly placed chargers when cars haven’t settled on a de facto location for the charging port.

Also they talk of a bus which can have multiple coils and can charge at 150kw whilst it’s stopped over a bus stop.

I know a while ago the bmw i3 was being tested with induction charging and Mercedes also showed a proof of concept car where you could get a charging mat for your garage and it could slow charge.

What’s everyone’s thoughts on these? Maybe if blocks of flats have these and there’s some sort of rfid and charge bump usage communal charging spaces could work out?

Might as well try as many different solutions as possible.

Not sure I would bother putting something like that on my drive when a cable will be cheaper, but it could work in some situations.

What's the efficiency of induction charging?

[peterperkins]

Won't the EMI tin foil hat nutters go into meltdown if they walk over/near one of them.

If you had a huge row of them in a car park and a block of soft iron on casters and some way of triggering them in sequence it might make an interesting linear motor or rail gun demonstration.

Quite an interesting way of abstracting electricity as well with no physical (cable) connection.
Just wind your own secondary coil mat and chuck it underneath the car on charge to power your own car/phone etc etc.

First thought was what happens if a cat goes over it? Or a kid trying to get his ball back after it goes under a car?

I'm sure they have tested it but do they have sensors to kill it or something?

Kill it? The cat or the kid?

It's incredibly rare for a child or a cat to have a pacemaker.

Supposedly, very good.

Think I’m missing something in the Physics. Why do people not like living under power lines but quite happy to sit in a car above power lines. Realise a difference in voltage but?

Do the same people have issues with inductive hobs?

I think any acceptable argument for fear about living under power lines evaporated when everyone decided to fill their house with wifi and wander around with a mobile phone containing several radios. And a CPU which runs fast enough to emit microwaves. These things are all insignificant enough to cause any harm, same as living under powerlines..

High voltage power lines do make a bloody annoying noise when it's damp though! Hopefully induction chargers don't.

Hummmmmmmmmmmmm...bzzztt.

Although we all know such houses are cheaper. It's not cricket in my book to buy a cheap house because it's under a pylon or the flight path and then complain about the noise!

Back to induction charging as a solution.. I'm just not convinced there's enough of a problem to need to be solved in the first place. Clearly most people can plug in at home with a normal and very inexpensive wall charger. For those that don't have off street parking - it's tricky right now but I seriously doubt the modern world will struggle in the next decade to find a way of getting power to street chargers in an affordable and safe manner. There's already quite a few solutions being presented to local authorities as possibilities.

Induction is by its nature more expensive and it's at its most efficient when the load coil is perfectly positioned - not ideal for a busy street of parked cars. A cable however...

Induction charging plates at bus stops (especially the end of route/ time check points) topping up buses when they're waiting a few minutes could work.

Or put them in the McDonald's drive through lanes :-)

I think the bus idea could work.. Sadly McDonalds are just too efficient to get a worthwhile charge in their drive 'thru's'

All these ideas could conceivably work in a minority of cases, but personally I don't think induction charging is the next big thing. Mankind simply needs faster charging and higher density batteries - not work-arounds to try and make the current battery tech slightly more convenient. That doesn't just make BEV cars more convenient, it's the same deal for your phone, laptop, torch, iPad, pet tracker, Nintendo switch etc etc etc. Double existing battery density and at a stroke everything takes a huge leap forwards, in terms of performance, battery life and degradation.

Or... bugger around with wireless charging along streets

I can see a few good reasons but none which are smoking guns.

Those with disabilities that can get by with adapted car controls but might struggle with with cables and connectors.

And also, when using the automated/remote parking features of some cars, there's the possibility of parking cars at greater density, and side/nose/rear charging ports would be an added variable to consider. Whilst an induction pad could make.ot relatively straightforward. Maybe with some alignment built-in.

And to my point... there are studies regarding the effects of lesser powered but far more localised EMF generators such as your mobile phone. If people are going to worry about one, worry about the other. Or worry about neither.

Or if you're very happy with your mobile phone yet passionately despise the power line overhead, then move house.

But none of these problems are a reason to stop having overhead powerlines, or, back to topic, potentially inductive street level charging (which I don't think is particularly useful anyway imo).

Maybe it’s only turned on when the car is in position.

I dunno, I’m just spitballing here.
