I found an article talking about this refresh. Apparently, it also is debuting at the same time as balanced power... They are introducing shared cabinets. Each pair of 350kw chargers will share up to 350kw. It says each stall is gauranteed a minimum of 150kw. However, the split isn't always half half like a v2 supercharger... It says if one car has a higher SoC and is only pulling 50kw, the other car can pull 300kw.
It also says each charger will now only have one CCS handle instead of two. It says each handle will have an 18' long cable. It says all future installations, will use these revised gen 2 chargers, with a single handle and 18' cable.. But it says the shared cabinets will be optional.
