When I wrote about Tesla's rapid expansion of its supercharger network, I was equally surprised by the extent of its less publicly touted network of "destination chargers"—slower, "Level 2" chargers that it is distributing to hotels, malls, restaurants and other locations so folks can charge while they shop/eat/sleep, and thus relieve some pressure from the faster superchargers which folks use for longer distance road tripping.
It got me thinking about another network of charging infrastructure which folks often don't talk about: The Level 2 chargers which most of us electric vehicle drivers install in our homes and—sometimes—places of business. These chargers don't just enable our own electrified driving, but they also provide some peace of mind to any friends and relatives who may consider driving electric, and who can now be sure of a charge if they come for a visit.
In fact, I've noticed several private charging station owners—especially businesses—in my region are publicly listing their charging stations on the various apps that are available for locating charging spots. Interestingly, this isn't just limited to restaurants or shops offering charging as a perk for your business: We have real estate companies and industrial operations simply offering up their charge points as a free service to the electric vehicle community. (Often, they'll stipulate—quite reasonably—that their own vehicles get first dibs.)
Is a network of free- or metered Tier 2 charging stations the solution to EV range anxiety?

Surprisingly, it's not as bad as it may seem at first glance. The base connector for Level 1 and 2 charging(110/240V@10-40A) is the J1772, which is nearly universal.
For fast charging, there are really only two options, plus Tesla. There's ChaeDMO, which is an older Japanese standard that's used on the Leaf and maybe a couple of other cars, and there's SAE/CCS (Combined Charging Standard), which is a J1772 connector with a couple of extra sockets for DC. Because there really aren't that many non-Tesla fast-charging stations out there, it looks like SAE/CCS will be the standard going forward, both because more cars already support it and because (I think) it has a higher capacity.

So there is Tesla, ChaeDMO, and SAE/CCS. That is 3.
Installing 3 different fast chargers at my house is probably crazy. A charger with all 3 is probably unavailable. I'm guessing that fast chargers are not cheap.
An electric car is much less interesting if I can't make a reasonable long-term investment in a fast charger.
