Dacia Spring 2024 battery CMFA platform, 27 kWh

Hello,

Here I will post pictures, any other interesting information about Dacia Spring 2024 battery CMFA platform 27 kWh

At the moment it refuses to answer any CAN messages

The CAN level is also jumping (no idea if this is the reason) CAN video (12V ON -jumping, 12V OFF -steady, 12V ON again jumping)

Small note! 12V on pin B, 3FB1 supply 12V only to the contactors. I would suggest to use separate 12V for A and B, in order to avoid transients from contactors going to the BMS,

Thanks for the great pictures @pavlik1.
Do you have also a picture with the service disconnect switch plug on the inside of the battery?
How may contacts/wires does it have?
I have recently bought a 2023 battery but it lacks the service disconnect switch

Hello. I may post a picture from the inside, unfortunately the humidity is 99%. Not nice to open the battery. In general, there are 2 busbars to the orange connector and 2 thin wites going over green connector to BMS.
