Bob - just purely considering from the mathematics point of view. Statistically, EVs may not charge at the same time, but as you mentioned, during time, people may more likely to charge roughly at the same time. [Or just look at Costco gas stations...] Anyway, if we have 100kw charging circuitry. And in a local community, all of a sudden, we have 10 cars charging at the same time. Then we need 1MW for a finite period of time. It may not happen now, but as more EVs are sold, the power surge will be an issue. More EVs + charging stations will appear to be even out the load, but statistically, the extremal case power load will be also larger. (unless the utilities can remotely control those charging stations power loads)
