Once SAE gets around to finalizing a real L3 DC charging standard, I think the situation changes a lot.
Right now, the CCS plug standard is limited to 200 amps. They then use 500 volts x 200 amps to claim 100 kW. But we all know that realistic pack voltages are 300-400 volts, so realistically EV's could charge at 60-75 kW off these 100 kW EVSE's if they could tolerate the c-rate. Right now, only the Bolt might be able to actually handle charge rates higher than about 75 kW. Therefore, the current CHAdeMO and CCS networks are really destination charging networks or urban commuter charging networks instead of really long distance charging networks between the vehicles available and the plug standard. After all, it is hard to install chargers in locations where the current crop of vehicles are not likely going to make it there in significant numbers.
For the automakers, they'd rather see that people are buying a vehicle like the Bolt in big numbers before investing $100s of millions into a charging network. Further, unless there is agreement amongst the automakers of a fixed equal contribution, why would GM sponsor BMW's charging? Or Nissan sponsor Kia's? Certainly not in a big way. So they take a bit of marketing budget to light up some corridors and most of that money goes into setting up chargers at dealerships that have some brand affiliation associated with that expenditure.
I think once the next CCS standard is finalized and equipment is available, then NRG eVGo, ChargePoint, SEMA, etc. can then whole heartedly install L3 chargers with the knowledge that upcoming vehicles will use them. The payback period stretches much further into the horizon. But the timing is more like standard finalization in 2017, equipment availability in sometime late 2017, 2018 model year cars might start to have it, so widespread deployment in 2018 to 2020.
If you look at 2018 or 2019 as years where the current 200 amp CCS plug looks dated like the 20-24 amp Blink J1772 network, then why put a lot of money today into such a plug standard? The ROI certainly isn't there. And CHAdeMO is likely to die regardless of its early lead in the L2 DC charging space. Both CCS and CHAdeMO have to start over at 0 installs of L3 EVSEs.
It will be interesting to see this shakes out in 2018. Will one buy a 2019 BMW, GM, VAG, or other product with a nascent CCS network or a more fully developed Supercharger network? When will Tesla make a CCS v2 adapter, or possibly even switch over, especially in Europe? Will Nissan/Kia/Mitsubishi be forced to CCS v2 in Europe and therefore eventually be forced by the market in the U.S.?
