Based on that pic you started around 60% and from the limited knowledge I have read/seen they will only hit close to 50KW at much lower state of charge. EDIT: I stand corrected, based on this video it started tapering at ~75%.
When I've gone to DC fast chargers (almost always EA) I've seen as high as 48 kW, and I don't see tapering happen until about 85%. Maybe the DCFC charger you were at isn't able to deliver higher than 30 kW regardless of what it claims.
Probably this. "50kw" charging stations almost never put out 50kw in the real world. Losses and misaligned specs won't allow it.
I'm guessing it's a ChargePoint Express 250 from the UI. The 31.25kW power modules are are capped to 78A with a >95% power conversion efficiency. Normally the CPE250C comes with 2 power modules so the reason why the second power module is probably the minimum duty cycle (>156A) wasn't met as the MINI caps off at around 125A.
Noice! Currently working my way down a Dalwhinnie 2006 Double Matured, though I prefer peaty Islay/Jura profiles to Highlanders.
I've only done 3 fast charges, so far. Power ramps up to a max of 49kW, then tapers. Maybe it hit 50 while I wasn't looking. Taper started before 85%. I think it was around 75%. I suspect the exact point will vary with battery temperature. I suspect the car limits charge current to about 122A. With a max charge voltage of 4.15x96= 398.4V, that's the 49kW I see. The usual way to charge LiIon is constant current up to a certain voltage, then constant voltage. This will produce first a rising, then a falling charge power. It seems Mini does that.
What is the outside temperature? In the summer I get around 50. Now that it’s cold it usually starts out in the 30’s.
It was 50 yesterday. I never used to pay attention but that day I was pressed for time. This wknd I will run it down to about 20% and use a different charger and see what I get.
I’ve been on this planet a fairly long time, and I have yet to try a truly high-end Kentucky, but there are so many satisfying products in the middle range — I especially like Blanton’s Original — that I don’t have any problems not shelling out $300 a bottle!
Have you tried this one yet? It's only about $110 or so. Have you tried this? It's about $110 so not to bad. I bought this just for the light. My girlfriend thinks I'm insane, which I may be, but it's fun.
