The specs of the cabinet show DC bus voltage of 800-1000v as well as all of the wiring to/from the stalls. Speculation: potentially they can upgrade the software and activate v4 on these.
V4 posts are being rolled out because they meet all the government requirements of having CCS and a payment screen.
Cabinets/switchgear will need the proper converters from 480VAC to 800VDC. That will not be a software fix.
Why not activate said CCS port and payment screen on V4s then? I've been to 3 and all of them had both deactivated/unusable.
Because those sites don’t have government funding therefore they don’t need those features. Just because they are there to simplify manufacturing doesn’t mean they need to be in use.
The documents provided show the V3.5 cabinet is already capable of this. The issue is they are de-rating the post to 500v dc max, yet installing conductors to support 1000vdc.
Surely it would still make sense for Tesla to make money though? My understanding is since they charge non-Tesla users a significant premium there's a nice profit margin for them compared to normal users.
They can charge non Tesla users who are partners with Tesla/nacs those fees through the app. They don’t need to have card readers to make money from non Tesla users. There are very few manufactures who haven’t signed on to NACS. Look at all the V3 sites open to non Tesla users, none of those have screens or card readers.
