Tesla would be silly not to be involved in the process for determining direction for major charging infrastructure plans.
At the least, they would likely want to make another CCS adapter based on the new standards, and what better way to have intimate knowledge of the technical details than to be involved in creating them?
Best case: The CCS folks see the light and adopt Tesla's IP for the next version and we get a much more usable (and Tesla compatible) design and capability.
It's possible you're right. I doubt the major car companies would adopt anything from Tesla unless forced. Nobody wants to admit Tesla is right about anything.
I just tossed a possibility out there.
I agree, at most Tesla will make a CCS adapter, and keep the Superchargers for Tesla cars only.
BTW, the 200 kW CCS limit is a nice marketing number, but it will be a long time before any car can charge at that rate. Current battery cell chemistry isn't there yet for automotive batteries. Because of this, people will not spend the huge extra money to provision stations for 200 kW since there won't be any cars that can charge that fast.
Look at Chademo as an example. While the current spec allow higher rates, the vast majority of stations peak out at 50 kW or even 35 kW.
The biggest problem with most CHAdeMO installations and most CCS installations to date is both have relied on businesses installing them for themselves and in most cases the charger is on whatever the largest breaker the business could put in. Because individual owners of chargers are responsible for maintenance, many break down and aren't repaired. They are also located usually singly wherever a business happens to be and probably isn't very convenient for long distance travelers.
Tesla took a much smarter and systematic approach. Each installation has multiple chargers, they are mostly located near major highways and most are in locations where people can go do something while their car charges. Tesla also got access to the neighborhood mains instead of leaching off an existing building. In most cases they have their own high power transformer at the supercharger. Tesla is also very proactive in maintaining superchargers. If any go down, they are on top of it very quickly.
Until CHadeMO and CCS installations start doing this, they won't be able to support an expanded BEV fleet for long trips. I think that will become glaringly apparent when the Bolt hits the road and new Bolt owners end up stranded because the charger they needed was broken and they didn't find out until they got there. If there are any regions which get a concentration of Bolts, there will be waiting lines at chargers. Meanwhile Model S 60 owners who only have a little more range than a Bolt can get from city to city with few problems.
Even if the CCS group rolls out a 200 KW charger standard and someone make them, very few will be found in the field capable of 200 KW. It's the fatal flaw in the industry's plan and management doesn't really want to do anything about it because it reinforces the theory that BEVs are more of a nuisance than the future. Though when the Model 3 hits the market shows staying power, the other car companies will start to panic and they will realize they are way behind.
If Tesla isn't offering CCS charging by then, somebody will have to bite the bullet to offer a parallel CCS charging network, which would be a major duplication of effort.
