Regarding Supercharger site "promises". I could've sworn there are ones around here that have rolled over 3 years in a row, no? Like the "Sicamous" one that's probably going to be Salmon Arm.
They are indeed being ridiculous regarding communication on that subject, but I'm still just surprised at all that they eventually build anything here. Such a small market.
I'm not good at wording things so they don't sound overly blunt, but...
They don't need it to make sense to anyone that's not an EE (or just not familiar with the specific context of it all). For example, the signalling pins. They might seem trivial to some, but they're absolutely necessary for a huge list of reasons, safety included. The experts work this all out for us, and it doesn't need to make sense to us. Primarily, there isn't much point building a separate DC signalling port if the AC port will work just fine without having to add more parts ($$$) and more complexity ($$$). CHAdeMO went that way, and look how it's ending up - nearing obsolescence (though I'm sure there's other reasons for this). Any consumer-facing standard that's overly complex and expensive to implement will eventually fall out of favour of the manufacturers. CCS Combo simplifies things (admittedly, this is a huge hand-wave).
Back to my original post ... Tesla supports CCS Type 2 but not Type 1 ... CHAdeMO is limited to 50 kW (essentially obsolete) and the Tesla CHAdeMO adapter is expensive at C$600 ... how do Tesla owners get access to the full (up to 350 kW) charge rate on non-Tesla charge stations in North America?
My suggestion: North American DCFC stations need to add CCS Type 2 connectors in addition to the existing CCS Type 1 connectors.
