Why can’t a battery-based car just use a step down to 12 volts instead of a separate 12 volt car battery?
In: 10
My understanding was it is just a cost saving thing.
They can use the 12v battery to power normal car systems/accessories without having to engineer/build new power systems. And also, the normal lights/accessories wouldn’t cause a direct drain on the main car battery.
While the main battery could be used to power the motor(s) and recharge the 12v battery like a regular gas engine does.
