Cybertruck SuperCharing @ 400V?

[CyberGus]

All Teslas have onboard DC-DC converters for charging
The CT will be backwards compatible with all superchargers
Tesla will make accessories for the new 48v systems. It should no big thing to get 48v to 12v stepdown converters and install it as the head of a 12v Subsystem but may require dedicated ground leads for anything attached to it

Teslas have AC-DC converters for L1/L2 charging, and DC-DC for providing 12V. When charging via DCFC (L3) the input voltage is applied directly to the battery pack.

Would be kinda cool assuming the pack CAN be split (and really that's the only acceptable 400v solution) if they put a second charge port on the other side of the car. As long as you are splitting the pack one option could be splitting it into two packs that could be charged from separate plugs.

Especially useful at slow DC charge sites, although you'd need a way to balance the two packs including keeping the first pack from charging until the second pack starts, and making sure they get the same power. Plus there would probably be a line of angry people forming while you use both chargers for one vehicle

This sounds like some of the solutions the guys have for charging their bikes. There are setups to dual (or triple) tap a Zero so it can get that full 21kW via AC. They love the Tesla Destination chargers because those are often 11kW and often come in pairs.

A Zero set up like this once grabbed the cross-country record from an Energica.
