donald said:10 minutes is too long. You need to be able to pull up behind a queue at a charge dispenser, pull up, plug in, go in to pay, then come out and go.
...
You might, I certainly don't. And what is this "go in to pay" thing you speak of?
There are other ways to do it, as we are already seeing.
As for managing queues, that is more a matter of supply and demand. How are queues managed at gas stations now?
If you have the proper number of chargers at well placed locations there will be no queues. While the rare station full can occur at even a well planned out and fully developed network, the queue management is simply go grab a parking spot and wait a few minutes.
