There is a CAN communication protocol documentation for the aftermarket EVPT chargers available, but unless someone actually logs the CAN communication on the stark itself it still is not clear. The build specification of the Varg charger is C1000 which is not listed in the EVPT docs so it might be something proprietary.

I thought about reverse engineering it, but first I'm onto something else, a lighter and more portable charger.
I worked on something similar with some contacts in my activity of tuning cars and swapping engines/ECUs with different CANbus protocols.

So it will probably need some sort of microcontroller to convert CAN to something like

While an automotive DC charger would be a natural choice, the connectors on those are pretty big already. So even if you figure out the CAN part, the adapter and cable would still be quite bulky as I don't think you could take a lot of short cuts with the voltage and amperage involved.

NACS is slightly larger than a normal gas pump nozzle. Maybe you mean CCS?

This picture from your link shows a NACS super imposed over a CCS.

Yes, unfortunately we don't have the NACS connector here in Europe - it is basically all CCS including the European Teslas.

On the charger cable Pin A=CanL Pin B = CanH
On the signal Cable Pin A=CanL Pin B = CanH
I have attached the Can 1000 Protocol.
I found this faultfinding the charger, not reverse engineering it.
I did find a resistor across the CanL/CanH at the signal plug, so this may be a dedicated Can just for the charge cct.
This picture looks familiar
I forgot to repost after I deleted my post on the other thread.
NACS or CCS, it's the same struggle, it would need an adapter but still a microcontroller like an arduino to "simulate" a communication between the station and the BMS.

Any updates?
The 6,6kW option was offered (temporarily for now) by Stark Future at the Gotland Grand National on dedicated chargers for Varg racers - the feature has been rolled out to all apps, despite 6,6kW charging not being available anywhere else.

in CAN topology every client has a unique ID. and every charger has the same ID.
You generally cannot have two devices with identical CAN IDs on the same CAN bus because IDs are for message arbitration, causing conflicts and data loss.
so… NOPE from the CAN point of view.
