Volvo EX30/EX60 V2L adapter parameters

Over time I bought several V2L adapters for my Volvo EX30, hoping one of them would work (even before software version 2.x), but none ever did. When the official V2L adapter became available (part no. 32411386), I ordered it immediately. This post isn’t about the official adapter, though. It’s about its electrical parameters, so you can build one yourself.
