I've watched as people say how "great" it is for the deployment of all of these charge stations around town. In my opinion people are missing the point and they will be a complete failure because
1) If you have a pure EV you can NOT rely on public chargers to get you home
Would you really go far enough from your home that you couldn't get back if the charger was down/unavailable?
2) People don't need public chargers for places they normally go
Most stores/malls/movies/shops are "close" to home...
The only type of charging infrastructure that makes sense to build are Highway based fast chargers. But when you think it through they don't make sense either.
The highway chargers would have to be spaced every X miles and whould have to charge fast enough that it only took 30 minutes or so to refill x miles. Any car that had X * 1.25 capacity would then be able travel anywhere there was a chain of stations. The trick here is how to pick X. Doo you pick a small amount (say 120 miles) that would require lots of stations or do you use a large amount (say 250 miles) that requires less stations but more expensive vehicles? Even then will someone who needs to go 600 miles *REALLY* be willing to add 2.5 (5*.5 for x=120) or 1 (2*.5 for x=250) hours to their 10 hour trip?
In my mind pure EV owners must give up the idea that they can travel beyond their range from home. At best they can plug in a work (commuters) or at a relatives (for family trips) but both of those cases are not public. To think that there will be systems in place to go on a trip "far away" a few times a year doesn't make sense.
If government/industry wants to spend money to encourage EV purchases they should make simple EVSE that plugs into a "normal" 240V plug available at reasonable cost (<$250) - they are only glorified GFI smart-switches after all
