What are the 7? In my experience, the two that really matter are J1772/CCS1 and NACS (Tesla). There's a scattering of CHADeMO, but I haven't yet seen a Level 3

What are the 7? In my experience, the two that really matter are J1772/CCS1 and NACS (Tesla). There's a scattering of CHADeMO, but I haven't yet seen a Level 3 DC charger that has CHADeMO only - the cabinet also has a CCS1 plug. Most (all?) manufacturers will be moving to NACS in the next few years. Luckily, J1772/CCS1 and NACS are protocol-level compatible, so adaptors are relatively cheap and easy to make. The remaining incompatibilities are commercial/business decisions (e.g. Telsa opening up the Supercharger network to other manufacturers). EDIT to clarify: I'm combining J1772 and CCS1 because there aren't any cars that have one but not the other. CCS1 starts with J1772 and adds a couple extra pins for DC fast charging (Level 3).

PHEVs usually only have J1772. Not that we need to charge at a station, but I'm happy to take a free charge when available.

  Eh, AC is nice for employers, hotels, RESIDENTIAL. But the shopping center ones are gimmicky. They're like 3.3kW with a 1kW TV next to it. Thanks shell.

I'm guessing that 7 comes from splitting J1772 from CCS1. It sort of makes sense, I guess. There are even a few EVs with J1772 but not CCS1 (eg, the early Chevrolet Bolt without the DCFC option). I agree with you, though. Splitting it out is weird at this point. It'd be a bit like pointing at all the different grades of gasoline and saying filling gas cars is hard. 87 octane, 89 octane, 92 octane, e-85 (try explaining the difference between the 85% ethanol and octane to people for some real fun), race gas, 100LL, ethanol free in several octanes. And that's not even getting into oil viscosities. Of course, the real world isn't hard at all. EV standards aren't really hard in the real world either, though there is a little learning curve.

  There are many plug in vehicles with J1772 and nothing else. See: almost any PHEV. Lol.
