I will be stopping at the La Posada hotel in Winslow, AZ. They have a HPWC, and the notes say... "The Tesla HPWC charges at 16.8kW per hour." I think in miles of range added per charging hour. What is this charge rate in miles per hour?
Few people have true 20 kW. I get 60 mi/hr at a true 20 kW (250V service * 80A, although some is lost to the cable dissipation). Most people have 19.2 kW (240V * 80A). So 59/19.2*16.8 = 51.625. But either way, it's close enough to estimate it at 3 * kW.
