Chademo is truly the Betamax standard, vastly superior but done down by commercial pressure exerted by the rival inferior system. You just have to read this forum to see the ongoing issues with CCS not to mention the absence of a workable V2G standard for it. So the EU and the German car industry have saddled us with a turkey.
Personally I would buy a car with Chademo for a four year ownership, but I wouldn't buy another LEAF given the continued passive battery cooling and associated degradation.
The problem is that no matter how great, and much better ChaDeMo is, if there are no charging stations, or only a fraction of the charging stations supports it, and no new stations with ChaDeMo is being added, and old ones replaced will also lose ChaDemo, then the ChaDeMo standard is not the best, because i can not charge it "anywhere", but at home.
To me, finding a charger anywhere i need it, is still a problem with CCS, and if there are a lot less ChaDeMo, that problem will just be compounded. Also less chargers, and longer distance between them means, not as much competition, and probably in the future, more expensive prices for electricity.
The CCS problems here seems to be mostly an incompatibility between the charger and the car, with regards to communications, i dont know how you could think this would be any different with ChaDeMo, if "all" cars had that.
The problem here for the charger owners, is that there is a standard, and if some manufacturers do not adhere strictly to that standard, there will be problems. The problem here seems to be with SAIC's implementation of the protocol, as no car should be able to get itself into an error state, that is not recoverable either by just unplugging the car or atleast a battery off, battery on, reset of the computers.
I even think MG have already solved this and any car that comes in for a service, will get updated firmware to deal with the problem.
These cars are more and more computer, and less and less car, so it is only logical that the cars gets some of the same problems as computers have had for years.
