At 9 gids the voltage spread was only 14mv. At 6 gids (turtle) it was 68mv 331v pack. Hx 60%.
When the QC charger said 19.8kWh delivered did that include the losses in the charger too? I noticed a big fan on the charger blowing hot air. If not then a more accurate estimate of capacity might be 19.8/28.5 or 69% but there would be some loss related to the battery heating up from 100° to 120° Plus the ac was on for 30 minutes.
I keep forgetting this was a DC charger. I don't know if the 19.8 kWh included the charger losses. It is probably vendor specified.
A/C use would be power diverted away from the battery, so the actual battery capacity is less.
No its power to the car. Now realize "that" power to the car also has losses but it fairly efficient. My average from DCFCs runs 94-96% . My guess is range is not that wide, its the accuracy of Nissan instrumentation that makes it that "variable"
The best way to measure power to the battery is thru LEAF Spy. I reset power meter before charge starts and it only records what is going to battery. You can test this theory by starting car and turning a power draw like AC or something.
