A Gateway module just hit eBay (https://www.ebay.com/itm/314423314345), $2,000, though it looks like it's been underwater for a month. New, Toyota's price is ~$2800.
The RAV4 EV Gateway ECU bears a striking resemblance to the Tesla Gateway module used in the early Tesla Superchargers, which leads me to wonder if a Supercharger Gateway (eBay https://www.ebay.de/itm/234267863745, ~USD$325) could be re-flashed to operate in the RAV4 EV. Physically, they look identical.
For reference, here's mine (Tesla 1010386-00-C; Toyota 89881-10R011):
(The blue OBD-like DLC3 connector isn't part of the Gateway, physically or electrically.)
And the early Supercharger gateway (Tesla 1032183-00-A):
The early Supercharger Gateways don't come up available all that often, but then neither do the RAV4 EV version.
