We discussed the possibility of using CATL modules from Peugeot E208 (and other cars) with the Battery-Emulator project.
This project gained popularity and now supports various EV batteries and hybrid inverters.
I'm a little skeptical about used hardware (ESP32), but maybe it's time to give it a chance

The CATL modules use MAX17823B together with MAX17841b for cell monitoring. The topic has been discussed on the forum many times, and some software implementation exists.
I've used and know these modules in some energy storage projects but with slightly different hardware (MAX17851 + STM32 MCU).
So, the task will be to interface the MAX17841b or MAX17851 chip to ESP32 and get cell data. For this, we will need an SPI port, and the first check shows that there is one. This port has been used for an additional CAN interface with MCP2515, so I believe it will also be for the MAX178XXX chips.
I will prepare some hardware and start testing in the following weeks.
Stay tuned
