Surely it would be enough in most cases to put an ordinary domestic single phase supply to each parking bay. No need to have big fast chargers. My Tesla S 70D gets about 1 km per hour per amp at 230 V. So if it sits there for an eight hour work day and can get 10 A (common for a domestic circuit in most of Europe) it would get 80 km or about 50 miles. Surely most people commute less than 50 miles each way?
- TomMarius 8y agoIt's easy to commute more if you're on a highway, your range in Europe can be around 150 km given 1 hour commute. My father used to commute 120 km (less than 1 hour ride on a highway).
- kwhitefoot 8y agoBut nonetheless most people don't commute so far. The average commute time in the US is 26 minutes (https://www.afdc.energy.gov/data/10801 https://www.afdc.energy.gov/data/10801), so probably less than 30 miles (each way I presume). And that amount of charge is easily done in an eight hour working day on a normal domestic circuit, no special charging infrastructure is required just a pole with a normal socket on it at every parking bay.
- TomMarius 8y agoYeah, but the average is most probably skewed by people who live next to their workplace. And still, even if it was just a fifth of people who commute from a larger distance, it's still a lot. Also, in the USA it probably works different than in the EU - the cities and rural areas look very different. Here it's extremely common to live in a village that's around 50km from the city where you're working.
- rconti 8y agoSure, but in the US on 110v we'd get maybe 4 miles of range per hour of charge. But I agree, it seems to make a bit more sense to simply have an outlet, but then there's the billing issue...
