50 kW DC is the charge rate of the rapid chargers in certain public places, never home chargers.Did I hear right? Did he say that it's got a 60Kw charge rate, or is that just the battery capacity?
Where I live several houses are fed from one pole transformer. Turn on a 6oKw charger and the whole neighbourhood's gonna go dim!
Tesla's dedicated public super chargers for their cars have a 120 kW DC charge rate.
Of course these public charge points have special mains feeds, newer UK homes these days have a maximum 22 kW AC feed. Older UK homes often have a maximum 12 kW AC feed or even less.
