48V was developed for that purpose. For example stage microphones can be powered by 48 V phantom power. Say if there are broken cables or rain, it's not nice to be shocked but it's not dangerous.
Many mild hybrid cars use a 48V system for the motor. It's probably going to get more common over time.

- Gravityloss 3y agoHmm does 48V really need to be disconnected? What's the reasoning? Honest question: is there something else than path dependence preventing just switching everything in a car from 12V to 48V? Even interior lighting? Ie is there some place where 12V is actually significantly better for physics reasons?
