Sure but they can feed the system through a regulator if they'd like. Do we have any reason to believe they are tapping directly on to a pack for this part of the system?
- SigmundA 3y agoNormally the battery is the regulator it serves to buffer inrush loads and absorb spikes.
- TaylorAlexander 3y ago> Normally the battery is the regulator For a 12v system, of course. But on a modern 48v system who knows what they decided. Having a switching regulator with built in current limits might be helpful.
- SigmundA 3y agoIts actually difficult to for a "regulator" to do what battery does, the battery can output significant surge as needed and its resistance drops as voltage rises absorbing large spikes without issue. In the Cybertruck there would need to be a DC-DC buck that could handle the 48v inrushes properly from the 800v traction battery and spikes would have no where to go as the DC-DC would not be bi-directional or even if it was could not react fast enough.
