[QUOTE="rjp44, post: 550402, member: 36221"] I think you misunderstood my calcs, I said 16A/charger [B][I]average[/I][/B] over the 12 hour night time period, to use in diversity calcs for cable and supply sizing. That is around 40kWh/car/day (1ph) or over 120 (3ph). For that not to be enough, all 19 garages would need to be stabling EVs that are all doing more than 120-400 miles [B]a day[/B] (44,000-134,000 miles per year!). I guess if every single one of the 19 flat owners is an EV taxi driver then you may get there. Seasonal variation is down in the noise within my 333Wh/mile pessimistic assumption for energy use.
