The child comments are a bit all over the place, but I can clarify.

At present, the Zombieverter supports:

Chademo CCS by interfacing with the BMW i3 LIM CCS by interfacing with the open source FOCCCI CCS controller.

The FOCCCI CCS controller is an associated project. See https://openinverter.org/wiki/Foccci

FOCCCI is the newest kid on the block, but it has been successfully integrated into several conversions now.

Very cool. Sometimes, DC fast charging is more accessible than AC.

It’s CHAdeMO - much simpler - and not CCS2

I am for sure not educated about the difference between CCS and CCS2 but it does say it's not just CHAdeMO https://openinverter.org/wiki/ZombieVerter_VCU#:~:text=ccs%2... and further down they cite a BMW i3 which I had and it fast charged to my satisfaction

Included me methods for ccs
