GLE 450 - 48 Volt System
I would love to hear some feedback / opinions and experience with the new 48 volt system. I found it incredibly smooth and quiet performance. I like the design strategy that pulled all energy consuming accessories away from the ICE and electrified them. My understanding is that the ICE is exclusive to propelling the car and the 48v systems handles everything else. I think this is a great way to transition until BEV's technology and infrastructure mature...

I don't know why more cars don't use 48 volt systems. The amount of wiring in a vehicle ads considerable weight. With all of the added electronics the current draws on today's 12 volt systems is much higher than just a few years ago. That requires more/larger copper wiring, thus more weight. Larger alternators.
Maybe the engineers are going to skip 48 volts as we move to hybrids and EV's where the battery voltages are even higher.

My Lexus Hybrid uses a battery pack that is somewhere between 300-400 volts DC (I would have to check the exact number). It then uses DC-DC converters to power things like the AC. It has a very small, but expensive, battery to power the main computer. I assume that other Toyota Hybrid Drive systems are similar.

48v system
I believe it also powers a supercharger to eliminate turbo lag. Here is a link that describes the functionality.
