VW Passat GTE battery balance problem with one module.

Post by tka »

Hi, all.

I have a VW Passat GTE battery.

I can't turn on balancing at CAN address 0x1A55540E and 0x1A55540F. (“module 3“)
I read the feedback balancing status from CAN address 0x1A555403. (“temperature and balancing”)
Modules 1,2,4,5,6,7,8 balancing works fine. I also get feedback of balancing.

Does anyone know why the balancing doesn't turn on with module 3?

I had the same with my golf GTE modules. https://github.com/Tom-evnut/VW-bms/pull/2 will fix it.

This is the case for any of the Gen 1, orange top modules (please correct me if im wrong). On the later modules, not orange tops those addresses are correct.

Hi

Now the balancing works. (“module 3”)

I changed the following CAN addresses:
0x1A55540E -> 0x1A55541E;
0x1A55540F -> 0x1A55541F;

After this, the balancing started to work.
The case has orange plastic parts. (“Gen 1”)

Thanks for the answers.
