Seems odd to gate it by model rather than by charging requirements. If this is a matter of the station verifying the vehicle type through the port, why was the CCS data protocol even designed such that it can be misused in this way?
The only exchanges that should be going on are voltage requirements, amperage requirements, maybe SoC, and maybe a secure payment ID. The station shouldn't be given the opportunity to care about anything else.
I am glad the stations are being opened up, regardless.
