DC Fast Charging is always a disappointment.

[billy_at]

My mistake, I was using Supercharger as a general term. I haven’t used the Tesla Superchargers yet.

Can you correct the title of the post to say "DC Fast Charging" instead of "Supercharging"?

Over the past year I. Haven’t gotten even close to the 150kW charging speed at any Supercharger in SC. I almost always get between 45-77. I few times I’ve gotten 120kW for the first minute but then it slows down significantly and it doesn’t matter what Supercharger I use. I have recently started programming the charger in the destination but that hasn’t made any difference. Is anyone else experiencing anything similar?

This sounds like an issue I had for a few weeks where Multiple 150kwh DCFC would stop at 70kwf for me. I posted here and someone from ford sent an update to my car and that fixed my issue been good for 4 months https://www.[Banned Site].com/threa...his-is-a-battery-issue.4237/page-2#post-60323

Just trying to understand what the battery minimum, battery maximum, and coolant inlet temperatures mean?

The first pic is when I left home this morning. I used the Ford navigation and selected a DC FC within 30 km of the house.

The second pick was in transit. I noticed the first thing to rise in temperature was the HVB coolant inlet, it actually reached 44°. The next thing to rise was the HVB maximum temp. and then the last thing to rise was the HVB minimum temp. Based on the numbers, I am assuming the preconditioning while in transit to a DCFC must have worked? And that it wasn’t just me doing regular driving that was heating up the coolant and battery? I’m not sure what the ideal charging battery temperature is?
Your thoughts? Ty

By the way, I was getting a solid 150 (151 to be exact) until 80% no matter where I began for the first 9 months I had the car. After that it has sucked ever since.

I don't think that is possible. Do you have the charging profile from those sessions recorded so you can share?

That’s how it should be, 160 kW peak on a 350 kW station, and 122 kW peak on a 150 kW or Tesla charger.

Other than the initial peak, either way most of the charge curve will be spent between 75 and 112 kW. Starts high and ends up 75-80kW from 52-80%.

Oddly, and I don’t want to jinx myself, but I usually have a solid 100kW on EA from 20 to 80%. It’s the only reason I don’t want them
Playing with my charge port.

100 kW should only last until about 30%. If you see 100 kW for more than three minutes above 30%, that would be extraordinary. And I'd really want to see the Car Scanner recording of that.

Replacing the charge port will have no effect on the DC charge rate unless the DC pins are overheating, which is not common. Charge curve is controlled by the BECM software.

Same here, this seems impossible. You'd have a golden goose if that were the case.

Next time I’ll remember to record it. I’m just leery of them fiddling around with it at all. I know the port shouldn’t have an effect though, but don’t expect it to keep doing fairly well.
