Looking into this a bit further I found this:
Position Papers & Regulation: Charging Interface Initiative e. V. (CharIN e. V.)
CharInEV is the organization behind CCS in Europe.
I quote from their website:
ACEA = European Automobile Manufacturers Association
Tesla is not a member of ACEA, but in addition I found this for the chargers:
I haven't been able to find where CCS is mandatory for new EVs, but it will be at least for all chargers installed later this year.
Really hope Tesla follows this route and we get CCS on Model 3.
Careful reading of CharIN documents (easy to get directly from them) show that most players in EV's globally are CharIN members including Tesla. The CHAdeMO older approach looks to be very gradually losing D.C. fast to CCS. Tesla will support CCS, and JB has long ago stated that Tesla cars are already software compatible with CCS.
To be clear, most NA CCS is a very early type that has little of the information exchange crucial to an industry-wide access system and is limited to pretty slow charging. However, a quick look at CharIN shows how they are future-proofing not only charging speed but, crucially, preserving a very wide option of payment choices (read the CharIN position paper on payments) so everything from "free for life" to casual payment by credit or debit can be allowed with plenty of options for almost any payment option.
Without question the CCS Fast connection is unattractive and bulky, but has very robust high-power-capacity conmectors. Native NA Tesla connectors will need modification anyway to allow for very much more than the present Supercharger loads due to overheating.
Not to worry. One way or another Tesla will have connectors and software logic figured out well before we fast ultra-fast charging.
FWIW, Tesla also participates in CHAdeMO, and their site is also informative.
Despite the early lead in some areas driven by Nissan neither CHAdeMO nor NA Supercharging connectors will dominate globally.
Why? Neither has the payment-system-agnostic system that CharIN has provided. Paying for charging is nearly as important as the electrical connections. Winner: CharIN CCS
Why? Only CharIN has membership that includes major vehicle makers, battery makers, connector suppliers, public utilities, charging networks and system designers. Neither Supercharging nor CHAdeMO really has those. Winnner: CharIN CCS
Installed base is another story. Here the whole world looks like Australia today, where one needs a plethora of inconsistent connectors, adapters and arcane converters/inverters to get around. In this respect it is much like the global traveler of the 1980's and before carrying a 100/240V inverter, an assortment of adapters. ( I still have my 1980 set, with nine adapters plus a bulky heavy inverter). All this inconsistency will not go away, but, high power DC Fast will end out pretty consistent because of the nature of risk in temporary connections at high power. That will happen because the risk of failure at very high power is really serious. The only widespread example today is that of aircraft auxiliary power, which is quite similar to the automotive DC Fast problem. Globally there really is a single standard for aircraft Ground Power Unit (GPU) connections. So there will be for BEV's, and it will be bulky to allow very high capacity.
