Elon Musk says ‘we dug our own grave’ with the Cybertruck as he warns Tesla faces enormous production challenges::Tesla CEO Elon Musk said Wednesday that the Cybertruck’s unique design means the company faces immense challenges in scaling production.
48v is in automotive as well. Most of the cable manufacturers are using PoE Ethernet. Belden has product lines devoted to this. It vastly simplifies wiring all the systems of a car together.
AFAIK Tesla is the first mass auto manufacturer going 100% 48v.
Others have a hybrid approach
I can see that 48v head and tail lights would cause a problem. It makes sense to start that on a vehicle that won’t see high volumes, since there wouldn’t be many needed.
