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
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.
