I think I spoke of this before. The place we stayed in the middle of nowhere had a SC station with about 10 bays in the parking lot. I know (have heard) that fast DC charging puts more stress on the battery than trickle or L2, and it seemed to me that it would be handy to stay in the hotel and overnight the car at L2, but SCs do not offer L2 (and man are those things noisy charging). But, given the NACS pinout, it seems like chargers that offer a charge mode choice would be fairly easy to implement as well as very appealing. Perhaps variable rate chargers will start to appear as charge points become more widespread.
It's possible, but generally the benefit of L2 on the EVSE side is much simpler requirements for power delivery/etc. This would complicate the handshake between the EVSE and the car, and as the CCS handshake isn't well documented, I can't say how well it will work. You could technically do it today, so long as the mode is picked before plugging in, but it does complicate the cabinet as it adds switching electronics to be able to pull from the big DC transformers or the AC from the grid (assuming it's not pulling in a feed from the grid at higher than 240V). I mostly want to see more L2 chargers at places because they are
much cheaper to install and operate, and at places like hotels, are all you really need.
With the size of EV batteries, L2 as implemented is effectively trickle charging. In Europe they don't even have the L1/L2 distinction. Split-phase is fun.
Guess my 80A tesla wall charger will retain its usefulness for the foreseeable future.
Eh, even if Tesla lost, I would have just gotten an adapter and kept a working EVSE. *shrug*
Either way, I don't have to worry about things for a while. Just give me a NACS->CCS adapter once they are available and I'll chug along.
My portable charger setup is a Tesla charger + TeslaTap because it opens up the ability to buy adapters that Webasto doesn't currently offer for 30A circuits that I'm more likely to run into in RV parks and the like. And it was about the same price, but now I have a way to plug into Destination chargers that aren't locked down.
