Setting max current over CAN

[ElMaco]

Hi,

I can't find documentation anywhere of how to set max current (in the inverter) to a value received via CAN (i.e. from the BMS). Is this not possible?

I would like the BMS to be in charge of how much current the inverter/motor is allowed to pull. My idea was to have the max output current, calculated by the BMS, presented on CAN and used by the inverter.

Any ideas?

I have a Leaf motor, EM-57, with a gen 3 gen 2 OI board. [edited for correctness]

Wait, you're successfully running a Gen3 OI board? I.e. in Leaf Gen3 inverter.

Apart from that, if you use the new "green" web interface you can map idcmax (accel) and idcmin (regen) just like any other item.

Hi johu, is there sarcasm in this part of your response ? What am I missing?

Gen 3 leaf board is a work in progress. We haven't gotten it to run yet. If you have a gen 3 leaf board working we would love to hear about it. There's a link in my signature at the bottom of this post.
If you mean a revision 3 or something else it would be good to clarify what you have.

Sorry about my misleading information. Blaming fat fingers. I have a Gen 2 OI board. I am correcting the initial post to avoid further confusion.

Great that there is an available solution to my issue. I will upgrade to the latest "green" interface and take it from there. Thanks Johu!

Been looking around the open inverter site for the latest files to update the web UI, but I can't find them. I am expecting index.* files, but can't find any.
Can someone please help me pointing out where I find the files I need to upload with the upload interface in the the web UI?

CAN or serial attached?
CAN: https://github.com/jsphuebner/esp32-web ... ckend/data
Serial: https://github.com/jsphuebner/esp32-web ... ckend/data

Well, I have been running FW 5.35, monitoring and editing over WiFi. My idea was to use the upload via WiFi to update the WebUI. I am afraid I don't understand the options "CAN or serial attached".

Can or serial is just the means of communication between the web interface and your board. For instance if you are using the external canbus datalogger you'd use the can version.
