I made a trip last night for the express purpose of testing 350 kW charging from a low SoC in my Taycan. I've visited 350 kW chargers before, but never with a low enough SoC to really expect peak charging rates.
A few bits of background/observations:
A few bits of background/observations:
- The trip from my home to the chargers was about 50 miles. I entered the charger as the destination in nav to get the battery pre-conditioned
- Battery temp on arrival was 85°F
- SoC on arrival was 6% (FWIW, Porsche nav predicted arrival SoC at 6%)
- Outside air temp on arrival was 44° F (a bitter California winter's night)
- It worked! Charging initiated without issue using the ChargingAmerica app on my iPhone
- Peak observed charging rate was 263.81 kW when I was at 27% SoC
- Charging plateaus at just over 200 kW for quite a while (the long flat part of the curve runs from 32% SoC to 56% SoC, and averaged 203.58 kW)
- The charge rate remained above 120 kW up to 79%
- During charging, the battery temperature was as high as 124°F, but cooled quickly when the charge rate dipped below 200 kW
- Recorded measurements started at 10%, but the charge rate ramped very quickly when I first plugged the car in. It was essentially the same over the 7-10% interval.
- I tried to measure the charge rate at least every 2-3%. Most observations were in 1% intervals
- I unplugged at 80% SoC
- Total charging time from 6%-81% (it inched up 1% as I walked to the charge port to unplug) was 22 minutes, 14 seconds
