Hello Zoe owners!
My damaged Zoe is driving now after big struggle. To make that happen, I had to repair the PEB by replacing the outer power electronic boards, I also had to replace the motor and at least writing it's roto winding resistance and rotor zero angle into the PEB. I did that with ddt4all.
Now the car is driving, but charging is not possible. It always triggers the fuses in my house (sometimes the RCD and sometimes the circuit breaker).
I think, that the BCB is also damaged. But my Autel diagnostic tool didn't find any issue.

I am very insecure of making further experiments with the car, because I heard from a Zoe garage that a damaged BCB can cause a motor and PEB damage.

I would like to replace the BCB, because I have a used one, but I read that it is also VIN coded.
Do someone know, which part of the BCB contains the memory with the VIN or is it possible to overwrite the VIN of the BCB or do someone have further hints for testing it?

Best regards

Hi,

I am in Switzerland and have as well a problem with my ZOE Q210. Each time I want to charge it it triggers the RCD. Renault kept it for 1 month now and claimed to have replaced some components, but not sure what exactly. They gave it to me yesterday back fully charged. When I came home and plugged it to the charger it worked few minutes then the RCD triggered again. Tried on a public charger : same problem.

I am very interested to see the outcome of your problem and what you can replace yourself in the car. Renault doesn't seem to be very prepared here to service those cars and their communication is very bad and protective.

Thanks.

Pierre

Which model year is it? On pre 2015 models, I got a word from EV specialists working on these cars, that the bcb can be replaced without being coded.

I will be mounting on my Fluence in about 1,5 months a sandwich of parts from a pre 2015 Zoe. The only thing that matters is that the peb, evc, bcm, immobiliser related computers and keys comes from same car.

I'm in the process of doing an extreme teardown of a BCB for my Youtube channel.
There are only two possible places the BCB can contain the VIN ( if it even does) - the processor board that sits on the IGBT brick ( it plugs on), and the board inside the filter block. My money would be on the former.
There is an EEPROM in the board in the filter block but I didn't see anything that looked like a VIN in it. I don't think there is one on the main processor board, but it could be internally stored in the Infineon processor.
Something I'd always recommend is to check with a multimeter that there is no continuity between the neutral and L3 pins on the charge circuit, as if there is, it indicates that the 1-phase charging relay contacts are welded, which is apparently is a known issue that can happen if the car has been plugged into a 3-phase charger that has a phase missing.
I'm skeptical about a bad BCB being able to damage a PEB, though couldn't rule it out.
