What are the charging losses for the DC quick charger? I just used one for the first time and it gave me 40% according to the dash and the DC quick charger reported that 8.7 kWh was dispensed. It also raised the temperature from 71F to 81 F (thanks LeafSpy) in those 15 minutes of charging. So if nothing else, I suppose that there was about 0.4-0.5 kWh (or more perhaps) of energy turned to heat during the charging process. So this alone makes the charging process 95% efficient at best.
A separate note is that this charger only dispensed energy at the average rate of 34 kW. I noticed in the charger's information menu that it was rated for 40 kW. But I also thought that quick chargers were rated for 50 kW. It did have a max current rating of 100A and max voltage rating of 500 V. Is this 34 kW typical for a DC quick charger? (It was an Eaton model)
This quick charger is going to be great in the winter so that I can heat up my battery to something reasonable (like 60) for a longer trip.
