What you may have saved on wiring is going to be offset by the increased cost of the battery (I'm seeing 2x-3x cost) and the fact you now need a much beefier alternator which is going to have its own cost.
You'd think if it were a slam dunk then the bean counters would have insisted on a transition to 48V years ago.
- jandrese 3y agoTotal current consumption should be about the same (or even less, thanks to lower losses at 48v), so I'm not sure why would you would need a "much beefier" alternator. It will need different windings, but overall it should be about the same size and cost.
- taylodl 3y agoOnce you've introduced a 48v system engineers will find ways to use that extra power. They've been spending decades carefully managing that power and making compromised. Now they won't have to. So yes, you're going to need a higher output alternator to keep the 48v battery charged due to the increased load.
