Wanted: SimpBMS CAN Extension

I'm looking for a SimpBMS CAN extension as an option to control my charger with a Volt pack.

Anyone have one they don't need?

Is it not just a SPI can module you want? The stock code doesn't support additional can interfaces. I've got code on my git hub for the VW and BMW modules that supports another canbus interface one SPI. I have charger on the SPI canbus and the modules on the built int.

The Chevy Volt software does support additional CAN via an extension module, because the Volt BMS and charger operate at different CAN rates. See page 39 of the manual.

Didn't know that, never looked at the Ampera code, it looks to be a serial can device. Is this it? https://www.longan-labs.cc/1030001.html

That looks just like it, thanks for pointing me in the right direction.
