Add support for PSA/STELLANTIS e-CMP batteries (Peugeot/Opel/Jeep etc) - Help needed

[albertofralbe]

Hi there,
I have a 2021 Peugeot e-208 100kW and I would like to help the adoption of this platform's battery that is becoming increasingly common in Europe. How can I do this?
I know that it has internal BMS using MAX17823 master and various slaves, one for each cells module.
