Using 48V Wiring Harness Not 12V
1. Using 48V architecture has helped Tesla to reduce the wiring by 77% and copper requirement by 50%. 2. If voltage is less then more current is required to meet power requirement. 3. If the current is reduced the heating effect in the harness is reduced as heat generated = I2*R*T which increases the lifespan and safety of wiring harnesses.
