Oh, boy, I guess all those Chinese consumers are going to be even more confused when they have GB/T on their cars. Tony, perhaps you should direct your outrage against the Chinese government, as they are insisting on introducing yet another QC standard, and in the world's largest car market no less.
I must be hitting close to home, eh?
Close to home? How do you figure, since I don't own any kind of EV and thus have no direct stake in any of the standards? I've said before that I think it's too early to worry about standardization when the number of PEVs is so small, and when many of the standards will be quickly outmoded in any case.

I'm not too concerned about any Chinese standard taking over the world, and by the same token, I'm very impressed with what they developed. It's the best of all the available designs that should work with AC or DC, high or low amperage, single or three phase, and smartly uses CAN bus control (as does every car built in the world), all in one plug.
Well, since we both agree that it's superior to CHAdeMO and CCS, and only Tesla is in the same ballpark technically but can't hope to be on more than a tiny fraction of the number of PEVs that will have GB/T installed, maybe it
should be the world standard, assuming you feel that such is required.

Here, I'll make one with hydrogen for you:
Protocol .......... US Deployed . World Deployed . US Cars . Worldwide Cars
Hydrogen................20....................40....................25.................100....
CCS Combo1 ........ 10 ....................10 ................. 150 ............. 150 ... (moribund)
CCS Combo2 ........ 0 ......................50 .................... 0 ............. 800 ... (moribund)
CHAdeMO ......... 600 ................ 3,800 ............. 50,000 ....... 140,000 (growing fast)
Supercharger .... 600 ................... 650 ............. 25,000 ......... 35,000 (extreme growth)
China GB/T ...........0.......................0....................0..................0
Chameleon AC ......0.....................100..................0..................15,000
Thanks. Let's check back in a year and see how the numbers have changed. Although I see no indication that CCS is moribund, given how quickly they're now starting to be installed in the U.S. and Europe
now that cars that use them are available for sale. As of today, the U.S. numbers are 11 plus 4 known under construction (I suspect a lot more will be going in at other BMW dealers), and I have no idea how many cars are equipped to use it. With the i3 now being on sale and having sold 336 (almost all BEVs) last month, and the Spark having had it available since late December and having sold at least 551 since Jan. 1st, 150 seems low.
As for Europe, CCS-2 seem to be springing up there as well: I count 14 sites total in Germany, The Netherlands, Denmark, Norway, Finland and Greece, and the four in the Netherlands all have two per site as does one in Germany.
As to the problem of multiple standards, sure it's an issue, but hardly an insoluble one, I like this listing from Plugshare, for a hotel in Germany listing all their EVSEs/chargers: EV Plug (J1772), Quick Charge, Tesla HPWC (Roadster), Tesla HPWC (Model S), EV Plug (Type 2), EV Plug (Type 3), Wall Outlet (EuroPlug), SAE Combo. And here's a location in Norway:
EV Plug (J1772), Quick Charge, EV Plug (Type 2), EV Plug (Type 3), 4 Wall Outlet (EuroPlug)s, SAE Combo.
As to H2, your listing of stations in the U.S. currently is too high as there are only 9 public ones, although several more are due to open soon. And your listing of the number of cars is too low, as there are a couple of hundred in the U.S. alone (ignoring buses and other commercial vehicles). By next year the number of both stations and cars in California will jump considerably.
