One of the things that will be needed is "redundancy" - this is to cater for the fact that an EV takes about 30 mins to get to 80% charge whereas, once you are at the pump, 2 or 3 mins is all you need. In short, when you pull up at an EV charging point or hub, there should always be unused charge points.
We also need to nail the "90% of people will charge at home" lie. As lies go it is a whopper. 40% of homes have no off road parking and, given the high price of EVs so far, it is overwhelmingly better off people who own them at present. Come the day, 40% of charging will be done at public chargers.
I'm sounding a bit anti EV these days - I'm not - but I have very little confidence that the infrastructure will be anywhere near good enough in time. I hope I'm wrong but until I see chargers in our local supermarket car parks (there are a handful at most) I will continue to be sceptical.
