I think if it was warmer, it might charge faster but not bad for winter. Was close to BMW stated specs.

Interesting miles per time analysis.

yeah, but it was not clear if he actually pre-conditioned the battery before going to the charger... I don't think he did... he just said he drove it "hard" which is not the same.

It's always better to charge the vehicle just after the trip, especially if on a road trip or several hours, than to charge the next morning when the vehicle is cold and batteries are cold.

55$ for full charge without membership… I think that's a lot of money. If gas prices weren't so high right now, filling up your X5 40i or something would only be mildly more than that. Just curious.

Well that depends on where you live and the gas prices there. Last week I filled up my X5 40i from pretty low in Plattsburgh NY and it was 100USD. I assume their gas prices are relatively high compared to the rest of the US though, but i don't think they doubled in the last year. Also note that the X5 gets more range than the iX on that full tank of gas.

But to your point, public charging is indeed relatively expensive. Here, they are still allowed to charge by the minute (which should be illegal). You can end up paying anywhere from 16.60$CAD to 47.31$CAD for this 83 minute charging session; Petro Canada 350kW charger in Quebec is 0.20$ per minute and Electrify Canada 350kW charger is 0.57$ per minute. You could save a bit at Electrify Canada by switching to the 90 kW charger when the car cant take more than that anyway and pay only 0.27$ per minute instead, but that would make it even more annoying.

That's basically the max charge for electricity, pretty much anywhere. The local average for gasoline here is consistently over $4.50, equivalently un-discounted. Filling up my 40i with gasoline to the max would be about $100. That's not mildly more, and that's per tank. Today. If I travel in my X5, the way I would with the iX, I could pay significantly more - the way I might be paying for electricity, at the mercy of gas on the road, to the tune of $ 5 or $6 per gallon - $120+ per fillup. Today.

If I "fill up" my iX at home, I pay less than .10/kWh. I don't get a deal like that filling up my 40i "at home," which will be 99% of my use of the iX. I get charged the same high-priced spread for gasoline a block from my house (I unfortunately, or fortunately, don't have a fuel storage tank in my garage) as I do 20 miles away. So fuel cost differences, gas to electric, are significant, wherever you get it, to the tune of double or more for gasoline compared to equivalent electric fuel traveling. Today.

Aside from travel, if you commute 300 miles or more per week here - easy to do - you'd pay about $85 for the privilege of driving on gasoline. Charging at home, I'd pay about $10 for the same range in the iX. Maybe the cost of gasoline will go down. Maybe electricity will go up. There would still be a substantial difference, and the extreme likelihood is that fossil fuel products will continue to increase in cost for the foreseeable future - and very probably at a steeper rate than we've ever seen. And be harder to get. Check the price of diesel in your area. Which, ultimately will drive up the cost of electricity, but not nearly as fast or as high.

So driving electric will always be more economical than driving gas or diesel. Maybe a lot, because there is potentially an unlimited supply, or maybe a little, because we might find vast reserves of oil we don't know about. Maybe. Enough to make up the cost differences in the vehicles? That, as they say, depends. I don't think we'll ever see $2/gal gas in America again. Ever. But it could get cheaper. Or the cost for producing electricity could get cheaper. Or either or both could get more expensive. As a famous American philosopher said “'It's tough to make predictions, especially about the future." But the virtual certainty is that electric cars will be part of it for the next decade or more.

Peak charging rate of 195kw and curve is average these days. EV's like Taycan and Ioniq5 are current charging kings. Taycan peak is 270kw and holds above 150 until almost 70%.

Would you then say without proper at-home charging equipment, it becomes a convenience game to own electric? Because the cost difference is too small at those outside charging prices given the time you invest to do it every time as well as the higher price of the vehicle? That is using your numbers of 100$/20.6gal for 40i engine @ 24mpg avg = ~490 miles; versus 55$ for 300 miles?
I get that it's still "cheaper" but I feel the difference isn't all that large that I was used to when I owned my first Tesla and charging was free. And that thing was inconvenient as hell without Tesla home charger. To be fair, seems that the new i7 would come with some time of free charging so that'd def be cheaper.

Exactly! Even so, if you’re using EA DCFC consistently, it makes sense to pay the membership fee once the complimentary 2-year subscription expires.…. It will add up quick.

I'd personally not own an EV if I could not charge at home even if public charging was the same price. That is easy for me to say though since I can indeed charge at home.

Having to sit at a charger for an hour or so a week is a non starter for me. On a road trip, I can use the charging time to go to the washroom, eat, stretch my legs, etc. and mostly would have stopped anyway especially if it is a family trip. But my current 10 minute round trip to refuel (shell station is a 2 minute drive away) becoming an almost 2 hour affair (nearest public fast charger is a 20 minute drive away so just going round trip is 40 minutes lost right there) is a flat NO for me.

Same. Charging on the infrequent road trip now is actually practical with the expanding infrastructure and - better - charging speeds and technology in-car. But driving somewhere routinely to charge at home removes one of the primary advantages of using an EV for me, and would be less convenient in time than refueling my X5. And time is money. I do understand that particularly in the EU that may be a problem. Battery technology and charging speed will undoubtedly improve, infrastructure will undoubtedly expand, and fossil fuel costs will undoubtedly go up. Until those curves meet, we're still on the pioneer edge of practical EV driving - doable, but early. Still nice to be here....

Currently the regs in Canada state that any person or organization wanting to sell electricity or gas (excluding gasoline) on the basis of measurement must hold a certificate of registration issued under the authority of subsection 6(2) of the Electricity and Gas Inspection Act. So they can't charge per kWh unless they register and must charge on another basis, ie time connected to the equipment, which works out great for them. They won't abandon that highly profitable model unless forced to by changes to the regs.

Technically they're not selling electricity, they're renting equipment. If the rules changed to mandate that the transaction must be characterized as a sale of electricity, they would be forced to register and then the rules stipulate that:

(a) the unit of measurement for the sale of electricity shall be
(i) the watt hour,
(ii) the volt-ampere hour,
(iii) the var hour, or
(iv) the joule

The public electric utilities are provincially regulated and rates are set based on reasonable profits. I'm not sure if this would apply to non-utilities like Shell or Petro Canada, for example.
