Ingineerix Takes Us Inside A Tesla Model 3 Body Controller
Tesla Model 3 pushes the automotive industry into the future of how the cars will be made.
Here is a detailed look at the car’s Front Body Controller.
Ingineerix once more provides insights into the Tesla Model 3 architecture, presenting the VCFRONT (Front Body Controller), one of the three body controllers on-board.
It’s powered from the 12 V battery and distributes low-voltage power to other two controllers. The entire unit is highly integrated and fuseless (no fuse box).
