Does anyone have access to the 48V architecture document that Tesla has shared with a lot of automakers? There has got to be a PDF version somewhere.
It looks like they are employing 48V PoE (power over Ethernet) hardware and placing CAN bus over the data lines in place of Ethernet based on all the details. That would imply a large number of readily available off-the-shelf chips and gear.
Uncertain if Power over Ethernet is being used. But for communication, they have something they refer to as etherloop.
