Engineering360: "48 Volts: Time for a Jolt to Vehicle Performance?"

Hey,

Regrading the transition from 12V to 12v-48V, are we talking about fully electric vehicles? mild-hybrid?

Will the car be solely drive on the 48V battery? will there be a 3rd high voltage battery?

I find it hard to understand the uses of each power bus (12V or 48V).

How each of the batteries will be charged?

Thanks!

Tom
