Newer and first EV owner though a nerd who watches too YT videos to progress up the learning curve.
TLDR; charging speeds are much slower despite preconditioning and arriving at 10-20% SOC since November (i.e., Cooler weather).
350kW EA stations I visit about once a month (it's free) and generally do a charge from 10-20% SOC up to 80%. Would often see 250kW peak (275 my max) and that would often hold past 40%, tail down towards 150kW in the 60% range and really taper off at 80% down to 90kW. I might be slightly off on the curve but the main point is I would sustain over 200kW into the 40-50% SOC and only drop to 100 near 80%.
The last few sessions now that the weather has cooled have been much worse. I have about a 25 min drive to the charger and with preconditioning arriving with a temp in the low 70F range. Yesterday, started at 11% SOC - started at 200kW, ramped to 240kW for a minute or two, then back to 200kW. By 40% dropped to 150kW and by 50% stayed at 100kW. Battery pack temps never reached much above 110F (i.e., no thermal throttling based on my experience - that happens nearer 130F).
Looking for wisdom from the group - did try 3 different chargers, was an empty 6 stall (all 350kW) station that has given me "all the juice" often in the past.
Looking at a longer trip in the coming weeks (~2000 miles round-trip) and if anything can be done at the dealership to check would ideally do that beforehand.
