Hi. Are you sure this is true? It's been a long time since I had physics, but I remember Voltage = I(amps) * R (resistance). If we use the same amps for a given process, I = V/R. Therefore, if you increase the voltage, you can increase resistance (smaller wires) without affecting the current. But voltage and amps are directly proportional, not indirectly. Again, it's been decades since I had physics, so please correct me where I am wrong.Higher voltage means lower amperage - or more energy for a lower amperage. Amperage creates heat, requires heavier wires, more cooling.
So being able to run at a higher voltage means generally lighter weight, faster recharging.
But... Safety? Not necessarily. If you were pumping the same energy, the same speed, you'd get less heat. But if you want faster charging, you're going to push that envelope.
And higher voltage needs more special insulation, newer more expensive electronics, etc. And it could result in the installed Supercharger network being incompatible.
