Anybody know why new supercharger cabinets (still V3 but new part number 1908800-00-A) have a "IRA V3 SUPERCHARGER CABINET" label? Maybe it's actually referring to Bipartisan Infrastructure Law's National Electric Vehicle Infrastructure (BIL / NEVI), as there doesn't seem to have been much discussion about Inflation Reduction Act (IRA) potentially improving tax incentives for installing Superchargers.$7.5B for EV chargers is not from the IRA, it is from the BIL
What changes might have been needed for V3 cabinets to qualify for credits/funding? Perhaps related to the power requirements that V4 would presumably satisfy but not ready to deploy, so update V3 in the meantime?
