She mixed up kW and kWh. We were talking about charging speeds and she blurted out some numbers about "17 kWh" and that the charging stations at the free public charging are that fast. I talked to her about how the Model S can have a 1 or 2 10 kW OBCs (and with the HPWC up to 80 amps, provided it's on the proper circuit and that DIP switches in the HPWC need to be set). Her car is a 60 kWh car (per the 60 badging). I also explained to her that EVSEs can be a bottleneck.
The EVSEs at this free public charging location are 30 amp, per their Clipper Creek labeling. I believe the line voltage is 208 volts (common commercial power), judging by what I see in Leaf Spy. I did the math for her showing 208 * 30 = 6240 watts or 6.24 kW and explained that after 1 hour, 6.24 kWh would've come from the wall.
I mentioned the Tesla UMC and how it can go from 120 volts to 240, up to 40 amps. I mentioned how usually at 120 volts, EVs are limited to charging at 12 amps at 120 volts, for 1.44 kW. But she doesn't charge at home. Again, she was confused and said... I thought oh... thought you could get 4 kW at 120 volts.
I will say you exhibited much more understanding than I would have. I would have told her "the car thinks its done and that is all that matters!"
