US drivers drive 3.1 Trillions miles per year [0]. Every month, the 12 Month moving average has been going up at 5 billion miles [0]. So every month we need to install enough charging stations to charge 5 billion miles/year. Lets use a Level 2 charger that adds ~25 miles of charge per hour. So 5B miles / 25 miles of charge per hour / 24 hours per day / 365 days per year = about 23,000 Level 2 chargers need to be added every month.
There are currently about 44,000 Charging outlets in the US [1]. So just to keep up with the increase miles we drive each month, and not increase the percentage of electric vehicle miles, we need to install more than 50% as many charging outlets as have ever been installed EVERY MONTH forever. Time for that exponential curve to help us out some more.

- cbowal 9y agoFor comparison, there were approx. 168,000 gas stations in the US in 2004 [1] and that number had been steadily decreasing during the decade before (202,000 in 1994).

- flexie 9y agoYou forget charging at home. There are currently around 100M home charging stations in the US, most of them completely underused :-) So every home is a charging station and if the range for EVs keep increasing 10 percent per year we will reach 400 miles in 2 years, 500 miles in less than 5 years. By then, road side charging stations will be for people driving more than 7 hours in a day and for the very forgetful. I drove more than 300 miles in one day once this year, and I still haven't driven more than 400 miles in a single day this year. Even if you commute 30 miles to work and 30 miles back, you would only have to charge your Tesla model 3 in the weekends. In 5 years you could drive 100 miles a day and still only charge your EV every weekend.

- searine 9y ago98% of all charging on my car is done at home, at night. Charging stations are for long trips or connivence at points of interest.
