Charger Congestion a Problem for Electric Cars
...One obvious problem with the Tesla superchargers is that there are too few locations spread over too much space. Not too far to make it, but too far for an ideal safety net given the risk of a detour or delay. There are also not enough Tesla superchargers at each location.
I am hearing more and more that as Tesla owners show up at a supercharger location on a road trip, all four supercharge hoses are taken by other Tesla owners. And there are only approximately 5,000 Tesla Model S cars in the field right now. The quarterly deployment rate is 5,000, so the problem will double three months from now. Tesla is just selling too many cars!
Waiting behind another electric car while it is charging isn't like at a gas station, where you may have to wait five or ten minutes. If there is even one person in front of you at a Tesla supercharger, you might have to wait close to an hour. If it's a "regular" 240-volt AC charger, it could take many hours.
If things are this bad already with 70,000 electric cars on the road, including 5,000 Teslas, imagine a year from now, with well over 170,000 cars, including an estimated 30,000 Teslas, needing a charge...
