I agree that Nissan and Mitsubishi alone not are likely to hold the Chademo Fort for too many years. Having All the Tesla’s now potentially having access may give the connector a bit more life. If Leaf sales go up and they Launch a few more higher volume models, that would help too. Toyota is the other variable. The prime carries a Chademo, but not yet on the US version.
All That said, the number of Chademo stations is still going up pretty rapidly. A good chunk of those are EA, but not nearly all of them. The desire is to see more 2 nozzle stations over the single EA stops.
If the new China cars next year start using Chademo or Chaoji its a whole new ballgame as that standard goes up to a potential 900KW.
If Tesla sells its supercharger network or even access to it, that also changes the calculus quickly.
Chademo will be fine for next 3 years though surpassed by ccs in the next year in terms of total stations.
