I recently took a 200 mile trip with a 30 minute charge and 2 hour stop in between. I began by charging to 100% SOC and leaving immediately. My first stop was at an 80 amp charger, where I charged for 30 minutes from around 30% about 36% SOC. I drove to next destination and parked with a 32% SOC. I manually turned off the A/C to prevent cycling while getting stuff in and out of the car and left it parked for about 2 hours with an ambient temperature around 75 F. When I got back in the car to leave, it read 28% SOC and quickly dropped to 27%. I was a little worried because I had planned my trip based on the SOC levels and still needed to get to the hotel, which had a destination charger.
Luckily, I had plenty of charge left to make it to the hotel, and charged to 90% overnight. When charging completed, I returned to the car, which reported a 91% SOC. Not a big deal, but I've never seen that happen before. I reset the charge level, thinking I set it wrong, but this behaviour continued until I set it to 88%, charged it, then 90% again next time. My 90% range estimate dropped from 245 to 241. I would think it just needed recalibration except I had just come back from a 300 mile round trip to Atlanta, exercising the SOC from 100% down to 25% or so and my 90% was still 245 after I returned.
I spoke with the SC and they said the battery checked out OK. They said the battery was a bit warm (30C - is that warm?) and that the coolant loop was running. They confirmed the HVAC was off while parked for those 2 hours and really didn't give me any useful answers. 4% would be a 1.5 kW average draw over 2 hours - about like running the A/C. Anyone else have a similar experience?
