Foccci board as Chademo to CCS conversion

[PaulHeystee]

Hi, I am looking to convert my Leaf Chademo to CCS by using the Foccci board. Does anybody have any experience with it?
Will the Focci board understand the Leaf Chademo talk to make the CCS2 work?

You just need to find out the battery pack voltage which is not on the chademo CAN
SoC is available, maybe you can calculate a rough offset and gain to convert it to voltage

Thanks!, I think i can arrange something. If this works I can now have a permanent CCS2 on my Saab, instead of the cumbersome and expensive adapter. I am planning to built the second one, again Leaf (160 kW), however, this time with Peugeot battery modules.

Great project! Together we will make this work. In case we need to adapt/extend the software, it would be helpful if you have the possibility to log the CAN (e.g. with SavvyCAN) and to make a serial log of Foccci (using a serial-to-USB adapter and any terminal program).

I have the battery pack voltage from the Leaf BMS, so that's no problem. I only need to find a way to get this can message to the Foccci.
I am surprised that the Chademo does not have the pack voltage included in it's CAN set.
