European countries have a much easier time than the US in this regard due to 220V mains voltage. Even with a standard outlet you can fully recharge a Tesla overnight.

> Even with a standard outlet you can fully recharge a Tesla overnight. Nah. 230V 10A is about 2kW and 15A about 3kW. More realistically it's 24h for a 20-80% charge. That said, 2kW is a 10kmh charge, so "overnight" (let's say 12 hours) you can do a 60km commute from a regular socket.

  It's at least fairly cheap to install a standard industrial outlet (single phase, or three phase if the house supply has it -- this varies in Europe). That looks to be what older/cheaper street lamp installations have -- a domestic outlet isn't appropriate for outdoor use anyway. That gets 7kW or more. From https://www.spiritenergy.co.uk/kb-ev-understanding-electric-car-charging https://www.spiritenergy.co.uk/kb-ev-understanding-electric-... : > If you have a standard domestic single phase (230V) supply, you won't be able to achieve a charging rate of more than 7.4kW. Even with a standard commercial 3 phase connection, the power rating for AC charging is limited to 22kW. 22kW is plenty, and e.g. my apartment in Denmark has a three-phase 40A supply, so houses surely have more than this.

  Sorry "fully" was the wrong word here: Standard European wall outlets (Type E & F) are 230V and 16A, so that gives you 3.7kW. At that rate, the Model 3 can charge at 22km/h [0]. So you could charge 20% - 80% (220km of range added) in 10 hours overnight. Even if your "overnight" time is a little shorter, that is still going to be enough for most commutes.
