As an EV x2 owner, this works now, because we are a small subset of the driving population. As the EV adoption increases, we will find lines waiting to use DC fast chargers. So, let’s take a gas station on a heavy use highway like the NJ Turnpike. It is fair to say they have 12-20 fuel pumps servicing all the ICE vehicles that come through (ignoring the truck pumps and trucks). How many EV DC chargers would you need to ensure EV owners can pull up, wait 10-15 minutes (like I often did in line for a pump), then be able to charge in 10 minutes?
We will need some serous numbers of chargers to facilitate road tripping EV owners once adoption is anywhere close to 50% of passenger vehicles. 15 minutes per user really ties up the “pump” if there is a line. You also can’t go inside and leave your vehicle at this time.
So it is something we will have to find a solution to. But, as we EV owners know, this only happens during trips, we save time the rest of the year, when we can charge at home.
