Charging Speed thoughts.

[eponey]

Had a chance to do a road trip, I had a few big charging sessions from the teens to 80% and the ones I bothered to do the math on the car averaged 92,92,99 kw/h speed.

That's not so bad, is our car not that bad?

It really tried to camp out at 100 for most of the time at 20-80.

Anything above 100 kW is doing well on the Mach-E. When it drops below 90 kW, I start thinking about leaving.

Mach-E is slow compared to other EVs that easily average over 120 kW.

If you’re a glass half full kind of guy, … that ain’t so bad. Could be better but not too bad. Depends on the strength of the charger and your battery size. The bigger battery charges at a faster rate than the smaller one and of course, higher power chargers can deliver a little faster rate at the beginning. For instance, an EA 350kw unit will give the full 150(maybe plus a little) at the beginning on a low battery. The 150kw unit will start at about 125kw. That initial faster rate from the faster charger brings down the overall charge time by a couple minutes. The key is that the car determines the charge rate up to its maximum of 150kw.
I think that most of us would like to see things move toward the 800v batteries of, say, the Hyundais and Porsches with a commensurate faster charge curve. They advertise around 20 minutes of charge time in lieu of our 30-35 minutes. In my case, after 4 1/2 years with the MME, I’ve gotten used to the 30-35 minutes and it really doesn’t bother me.

I am OK with the slower charge rate during long trip. I rather take my time rest and eat during the charging than doing it in a hurry.

Model Y averages about 100 10-80... According to the interwebs....similar to the id4 as well....nowhere near the 800v cars or faster 400v like a rivian but it's not that bad, at least on this one trip this time. Just surprised when I actually did the math.

That sounds about right. I just figure, about 30-35 minutes for a road trip fill up.

This depends a lot on the charge curve.
Note I have a standard range LFP battery.

23% to 80%, 45kWh in 26 minutes = average 103.8kWh.
19% to 61%, 33kWh in 16 minutes = average 123.76kWh.
26% to 85%, 45kWh in 33 minutes = average 81.81kWh.
52% to 80%, 21kWh in 15 minutes = average 84kWh.

Note that I pulled these numbers out of the Ford App under the Charge History.

With my standard range battery, what I would like more than speed is some more range.

After several hundred DCFC charge sessions, my long-term median charge rate for the Mustang is 85+-5 kW. My long-term median time on the charger is 25+-5 minutes. This is just enough time to grab a bite to eat, use the restroom, and get back to the car. I truly don’t want a much faster charge rate for the Mustang. There have been a few times when I wished for a faster rate, but there have also been times where I’ve paid idle fees because I wasn’t able to get back to the car soon enough after it finished charging.

Well it had me thinking as far as vehicles go if you level 2 at home the differences in the charge curve get smaller on long distance road trips. I think it's maybe a different story if you rely on frequent DCFC.

On Level 2, there is almost no charge curve, at least until you get really close to 100%.

With DCFC there is a very big charge curve. Typically, if I start charging at between 10% and 20%, I will see it start charging at about 135kWh. As it gets over about 60% it is already tapering down quite a bit, as it gets near 70% to 80% I think it is in 80kWh range.

Note we only use DCFC for the few long trips we make.

My 820 mile road trip last week was mostly drive around 2 hours, charge for around 20 minutes and then go. Not much different from when I use my Rav4 hybrid.

Against the MME, the Model Y is both a lot more efficient and charges much faster down low. Out of Spec Testing recently did an 80mph test after a 15 minutes charge from 10%. The 2026 Model Y LR AWD was able to charge from 10% to 57% (36kWh added) and traveled 126 miles before again reaching the 10% SoC mark.

On a recent road trip, i added 40kWh in 24 mins (100kW avg) starting at 25%, ending at 71%. That was after driving 172 miles starting at 100%.

It's not great, really. The 2021-2023 cars are especially slow. The latest iterations of Hyundai/Kia's are nearly twice as fast at charging and they're now sporting larger 85kWh battery packs against the 2025 MME's smaller 88kWh pack.

The MME GT is especially inefficient, so it's a double whammy of less range and slower charging.

Wait, isn’t 88>85?

2024 MME had a 91kWh pack, the 2025 went to a smaller 88kWh pack. Meanwhile, the Korean EGMP cars went from 77kWh to 85kWh.
