Ai sin forklaring (som man jo alltid må ta med en klype salt)
A typical modern truck with a 12 V architecture can have:
50–70 kg (110–155 lb) of total wiring harness mass
Of that, ~15–25 kg is heavy-gauge copper for high-current 12 V loads (windows, steering assist, fans, pumps, etc.)
If those heavy loads move to 48 V:
Copper mass for those circuits could drop by ~75%
That equates to roughly 10–20 kg (22–44 lb) saved
Industry teardown estimates suggest Tesla’s 48 V move likely saves around 15–20 kg (30–45 lb) of wiring in a vehicle the size of the Cybertruck.
