No. You are not being trolled. And I do not think you are trying to troll me. You don't seem to fully grasp the distinction between energy and power and I was trying to clarify that but certainly didn't help matters by either sticking in that extra "k" or leaving out the decimal point (as you...

I don't think the guy is trolling. He's just hung up on kW vs kWh or something like that. Or I made a stupid math mistake.

Correct. = 1440W. Correct OK OK = 60*1000/1440 =41.7 min. Correct. What is it you are not understanding?

??? 6 kW for 10 min (1/6 hr) is 1 kWh. 120 V @ 12 A is 1440 kW. Thus the 120V charger will supply the energy necessary to precool your car in less than an hr.

In the US it's going to be 240 (or 208) for a long, long time on the voltage. The current Gen 3 EVSE max out at 48A. The Gen 2 went up to 80 and it does stand to reason that faster charging will be wanted for the CT with its battery double the size of the largest they have on the market now. And...

Thanks!

The current ramps up in less than a minute as the EVSE does some tests on the connection and then holds steady at whatever current level you asked for until the charge is complete at which time it ramps down to 0 over a few seconds.

As the first quote is dead wrong I wouldn't say the obseration was particularly intelligent.

Suppose it depends on how you describe “mass” but BMW is making this available to its customers. Try to understand how it works and perhaps you will stop making such foolish statements.

Rather than have more and more posts based on conjecture based on lack of understanding of electro magnetics perhaps it is best to explain how these things do work. The basis is a coil in parallel with a capacitor forming a resonant circuit. If you really want to understand how the system...

It is efficient (90%). Whether it is practical or no remains to be seen. The people making inductive chargers certainly seem to think it is.

No because that is not required. A foot or two separation is fine. Clearly you do not have a clue as to how this actually works. Perhaps it would be better to leave the engineering to the engineers.

My phone does charge through the air as does my toothbrush and as do a couple of cars and trucks. Charging inductively at L2 rates with 90% efficiency has been demonstrated in both commercial and private vehicles and several manufacturers claim to be a year or so away from offering systems...

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.

Given the performance of the current beta I think it obvious that FSD as a practical matter is years off. It is amazing what it can do and at the same time amazing what it can’t.

I wasn’t asked to sign an NDA.

FSD involves AI and AI is a special case. Intelligent people, like E.M., see the promise of AI and get so excited that they fail to see its obvious fundamental limitation. "By the end of the year" promises surrounding AI based systems started with Norbert Wiener in the 50's.

Those of us who know a little about investing are familiar with all the caveats that go with "forward looking" statements made in financial documents.

It's not a question of want to, it is one of must not. Code requires derating of EVSE circuits to 80%. The current crop of chargers across OEMs seems to be rated at 48A (11.52 kW - input) max. EVSE that will deliver that maximum must be on a 60A (or greater capacity) circuit.

Why would you expect this year to be any different from last year, or the year before that, or....
