Could you please elaborate on: > I'm actually being taxed for owning an EV.

Alberta is imposing a charge on EV registrations, and they increased it again this year. At some point I'm hoping courts curtail their attempt at imposing gas cars but given how Canadian courts are hamstrung at obvious human rights issues in places like Quebec, I doubt they will do anything about Alberta either.

Paying the fair share for road maintenance isn't a human rights issue.

>Just taking an existing fast charger with 150- or 350-kW capacity and swapping in the latest and greatest 1,500-kW chargers wouldn’t get anyone faster speeds. The system would need all new “pipes”—grid capacity—to actually move that much current. The grid doesn't necessarily mean "pipes" or power lines. You don't build a pipeline to every gas station. Mobile charging robots work pretty well in China.

Also I guess they could put a large battery at the charging station so it can take say a steady 200kw from the grid and be able to kick out 1500kw for ten minutes occasionally. That could also charge from cheap off peak electricity.

This is what they already are doing, the article is behind a paywall so no clue if they say it there but you can for example see this article about it: https://www.etechvolution.com/p/byd-megawatt-flash-charging-...

Although the thought of getting an electric car has passed through my mind on a few occasions, I'm not 100% familiar with the intricate technical details. (for some reason, the tax incentives where I live are still in favor of continuing with the small petrol car I have. Taxes are primarily a function of weight in the Netherlands, and anything besides a lightweight Dacia Spring would imply significantly higher monthl…

Rule of thumb for modern EVs is to not care about the battery at all. They are expected to last longer than the car. I would doubt even faster charging significantly changes this, or if it does it’s worth the trade off to those who need it.

+1000. Who cares. It's good enough.

America certainly did not invent electric cars. Depending on which electric car you consider the first real one, the inventor was either French, British or German [1]. [1]: https://en.wikipedia.org/wiki/History_of_the_electric_vehicl...

GP is talking about the current market and product class, not the drive train/mechanisms. There was ~a century where EVs were effectively nonexistent

If the GP was aware of the history of electric cars, they would have known how to word their comment to be factually accurate.

dont say that or used EV prices are gonna skyrocket :)

I think you'd have to be a bit ignorant of very recent history to think that America is some cesspool of lack of innovation in the electric car industry. They invented it, despite there being no competition at the time.

In “recent history”, America invented EVs, and there was no competition? What kind of revisionist crap is that? Or am I just misreading your comment?

Reference to perhaps GM EV1 in the 90s, and to Tesla which actually made electric cars desirable.

Reducing carbon emissions most certainly is a human rights issue. I absolutely can not breathe when I go to large cities. I live in a village, drive an electric, and charge it from rooftop solar.

I have a feeling that half the reason they're doing this is that they don't have a good idea how to increase energy efficiency. Case in point: 2026 BMW i3 - 900km WLTP from a 108kWh battery. 2026 Denza Z9 GT - 800km WLTP from a 122kWh pack. The former charges at a maximum of 400kW, while the latter at over twice that which saves... about 10 minutes at the charger after 450km of driving(12 vs 22 minutes approx). Many…

> 2026 BMW i3 - 900km WLTP from a 108kWh battery. I had to do a double take: remembering the i3s as the little almost SmartCar-sized EVs. Great cars, I still see a few around here, but I couldn't imagine them extending the range of those to 900km! Turns out they just released the i3 sedan, which is like a 3-series. And good to see they're making the design similar between the new 3-series and the new i3. I like the i…

Yes that new one is not an i3, not even in spirit. The original i3 was super light, quirky, fun, innovative in so many ways. They just didn't sell enough. People wanted more boring cars.

Supercaps are viable for this sort of short term charge and discharge. The much maligned donut labs is suspected to be a license built Nordic hybrid supercap battery model
