This is false on multiple levels.

• There is no such thing as a "CCS" plug. Most countries outside North America and China have adopted CCS2, which is incompatible with the CCS1 plugs found in North America.

• China use their own standard for DC fast charging, GB/T. With respect to dreams of a "global" standard, this isn't mere trivia as China has significantly more EVs on the road than any other country.

• Japan still uses CHAdeMO.

• In North America, there are significantly more cars on the road with NACS plugs than with CCS1, and there are more DC fast charging stalls deployed with NACS connectors than with CCS1. (And that's including the many CCS1 stalls which aren't currently working.)

In the US, Tesla + GM + Ford represent over 70% of electric vehicle manufacturing. Tesla represents the vast majority of high-speed charging stations.

Hardly niche.

How often do you drive your car from North America to Europe?

I chafe at the US (and NA) tendency to stray from otherwise global standards, but in this case I'm not convinced it really matters. Car companies are already really good at localizing vehicles to regions, so that's not an argument either.

CCS1 (North America) has approximately a 1% worldwide market share. It's not surprising that it is dying.

CCS2 (Europe) has a sizeable market share.

CCS1 and CCS2 are incompatible.

Ford and GM have also announced they are adopting NACS.
