The CCS may not be first but it may be better for the consumer. Significantly faster charging time, a car charging port that takes less space, and Level III that can't be sold as an "option" seem to be the major advantages.
All Level III charging is truly a wall or pedastal mounted battery charger putting DC input direct to the car. Level I & Level II use on-board chargers receiving conditioned AC from the wall or pedestal mount units. I have recently read about the Volvo 3-phase on-board system as well and there is, of course, the Tesla system. Nothing is set in stone at this early stage except that BEV's are here to stay. As it progresses the EV industry will shake out winners and losers but the focus for survival must be on what's best overall for the BEV to compete with the entrenched highly-evolved combustion engine systems in use today.

But it was mainly the 800lb Gorilla GM that used it's lobbying and campaign-funding monies to get ccs, SAE & Gov. accepted. http://www.greencarreports.com/news/1075897_new-sae-fast-charging-standard-to-be-shown-next-week ' ... Audi, BMW, Chrysler, Daimler, Ford, GM, Porsche and Volkswagen are all on-board with the [ccs] charging standard ... It may not be pretty, but the aim of the plug is to standardize charging [&] take as little as 15-20 minutes. As well as the fast DC charging, the plug also allows for one-phase AC charging, fast three-phase AC charging, and home DC charging. There is of course one issue for many current electric car owners, and that's the incompatibility with the Nissan Leaf and Mitsubishi i. The Japanese cars both use the Japanese standard CHAdeMO charging system, which uses a different plug and different charging architecture ... ' It is my understanding that to try to carry around an adapter for the ccs, the designer would need a to know the ccs protocols used (the network handshaking software bit) so the ccs EVSE could be fooled into allowing power to flow, and then that ccs AC power would have to be converted into the DC the CHAdeMO port uses. That hardware may be too heavy and or expensive to carry around. Until ccs is actually out in the public and or its design spec is made known to the public (likely not going to happen), it will be a guessing game. ... This reminds me way too much of GM's successful efforts to dilute installing public EVSE. GM said their proprietary inductive was safer, but the EVS-12 sales reps confided in me that it was really to keep GM from being sued (no metal to metal contact. With ccs using metal to metal, I guess GM feels now they will not get sued). GM's inductive was only available to those Automakers that paid to use it, so it was unavailable to all other Production EVs and the conversion EVs (EVS-12 GM sales reps despised the conversion EVs that were at the show). Today, what few (old version) RAV4-EVs there are that use GM's old spi inductive EVSE, can carry with them a level-2 spi EVSE so they can connect it to j1772 power, or any other suitable power source (14-50, etc.). It looks like to me, GM is going to cause more harm with this additional L3 standard because EVSE installation grant monies will have to put in both CHAdeMO and ccs EVSE. Which was the same wasteful practice when both conductive Avcon and GM's inductive spi had to be installed at the time at a public EV charging installation. If GM had used the same EVSE standard, there would have been twice as many public EVSE installed (less wasted tax payer money - at the time, funding for the old EVSE installations came from DMV fees = the tax payers). ... But wait it gets better ... Not only is there going to be both a CHAdeMO and a ccs L3 standard to install, now Volvo has one as well (I have a piece I will be posting on this soon). It is a 90 minute, 22kW AC EVSE that uses a 3 phase 240VAC source. This may be yet another L3 standard (albeit low powered, slower one) to contend with. IMO I would rather go with the ~20 minute L3 EVSE we already have an abundance of, CHAdeMO http://www.chademo.com/wp/wp-content/uploads/2013/03/chademomap2013.03.11.png Map of all installed CHAdeMO EVSE worldwide {brucedp.150m.com} ... http://en.wikipedia.org/wiki/800_lb_gorilla - On Tue, Apr 30, 2013, at 01:43 AM, Dave Davidson wrote: > I'd like to see an adapter to allow Chademo equipped vehicles to use the > Tesla supercharger stations.
