Do you care about 1,500 kW charging?

[fleeps]

I think it is more important to increase the number of DCFC sites than to make DCFC faster.

Yes, I would be very interested in faster DC charging. Just returned from a 5,461 mile trip. On travel days, charged 3 to 4 times. Haven't added it up, but let's say I fast charged 35 times. 10 minutes vs 40 would be 30 minutes x 35 times = 1,050 minutes saved over 2.5 weeks.

We took the Lightning on the trip, which charges faster than the Mach-E, but has a bigger battery.

Of course I understand that faster charging requires different vehicles, but I've resigned myself that our future EVs most likely will not be Fords.

Yes, absolutely. It's the Holy Grail of EV adoption. It's usually the first (and sometimes only question) an EV owner gets. Once the encyclopedic explanation begins about all the levers, pullyes and planning one has to do in order to charge out in the wild, the eyes start to glaze over and the listener has moved on in their head, not really interested anymore in the EV experience.

It's a psychological construct. For the better part of 100+ years, filling up your vehicle in around 5 minutes has always been the standard. To take that away and replace it with a 30 minute or way more "fuel stop" is mentally untenable for the majority of people. So yeah, 5 minutes to "fill up" to 70-80% charge will undoubtedly remove that psychological barrier.

Two things I hear most often causing Ice-only owners to resist considering an EV: High cost of the vehicle and too long to charge. Call me silly but is sure sounds like BYD has an answer for both issues.

Practically, of course, our grid can't support it and we don't really need it, yada yada, but was just wondering.

Most of these have built-in batteries so they don't require a bigger grid connection.

I'd be very happy if my Mach-E just got the 150 kW it's supposed to. Typically, it will do that but only for a couple minutes. Then drops to 120 kW, then 90 kW. In the winter, even with preconditioning, seems like 90 kW is about the max. And I rarely charge past 80%, so that's not the reason it slows.

That’s normal. There is no EV that can sustain its charge limit throughout the whole session. Hence the term charging curve. They will always peak at the maximum limit down low and then start to slow down as the battery fills.

Yup. The charge curve on the MME isn’t anything to write home about and for the original 2021-2023.5 cars, it just sucks.

Here’s my charge curve and data for a session just a few days ago.

31% -> 63% in 15 minutes.
27.7kWh added
110kW average (but dropping fast!)

1500kW and an EV’s ability to take that kind of power would be a game changer for the EV industry in the USA. Sucks that we can’t have nice things.

Gimme ~ 50kW/h home charging. That'd solve both issues. Massive high speed charging would only help if a massive amount of people needed it. I get being ahead of the curve, but inventing it is a two way street that could end up never getting used.
To me, charging needs to become something you don't even think about. I like the idea of at speed road charging, that too helps in 2 ways by charging and not having to stop. But anywhere you stop on a road trip will be a ~20 minute or more stop from my exp with a family of 3 and a dog. The ~30 minutes the family ever spent at Walmart for charging was 'too long' according to the ladies that took 50 minutes to actually leave the Walmart. (Yep I'm in and out in less than 5 or buddies know to send a search party) So I sat in the car waiting for about 20 minutes.
50k home charging would be good for "oh crap I need to run to the other side of town and didn't charge, but I have 15 ~ 30 minutes"

Um, you already have 50kWh charging. Just plug it into your 48A wall box charger at 10kW and wait 5 hours. It’s like magic!

The current state of charging tech is 350-400kw, and that requires 800-900v. I will no longer buy an EV that supports less than 800v charging. I have 2 EVs that support 800v and for that reason I try to avoid Teslas old tech chargers. EA, EVGO, Ionna, BP Pulse and Walmart have left Tesla in the dust.

1. Do you mean kW not kWh?

2. Why would you need a 50kW charger at home? Do you often drive like 250 miles round trip back to your house then have to leave and do it again in 1-2 hours?

Home charging is typically done overnight, so it rarely matters if it finishes in 1 hour or 12 hours. A 40 amp (~9.6kW) charger can charge the car from 0-100% in about 10 hours. But most people only use 10-25% in a day so even a 16 amp (~3.8kW) charger is sufficient to replenish overnight.

Should post your charging curve

But at least you have clean coal and just won the oil wars ammaright?

In all seriousness; wish these welcome! On remote places it ideally should have a hand full of stalls on the same chargers so that it can charge many cars and split the effect. Then if lone charger then enjoy ultra fast charging.

I have a Hummer EV and an Escalade IQ, they charge the same as the Silverado EV:

At 75% the battery hits the peak voltage, so it just ramps down from there based on the pack resistance. Usually I do not drop below 200kw until 75% then am still getting 160-180kw at 80%.
