Thank you for the pictures. I also have a Zoe, where I had to repair the PEB and replace the motor. Now the car is driving, but charging is not possible. It always triggers my fuses in the house. I think, that the BCB also is damaged.
I am afraid of driving the car, because I heard that a damaged BCB can cause a motor and PEB damage.
As I have a working BCB I would like to replace it, but I read that it is VIN coded. Do someone know which part of the BCB contain the memory with the VIN?

Best regards
Juri

In reply to Richard Ford-Hutchinson.

Thank you Richard! But those could never be the N-L3 charge current switches it seems…..

Edit: I retract that statement. 48A relays. That should not be a problem at all. One of the two seems to short circuit the pre-charge limiter resistors (3 x 33 ohms parallel)

In reply to Jeroen Meijer. There are two relays, Panasonic 21003W ones, mounted underneath a 4th small circuit board hidden under the board to the right of the black plastic moulding containing the two heavy coils. What these relays do I do not know.

Hello, I play with the idea of completing a DC charging on the ZOE Q210 is there any way to have more original schemes from your contact? Is it even possible to make a DC recharge to the ZOE? I am interested enough, but the information is little ….

In reply to Daniel. Nope, the drivetrain and charger is different, but hey, while most stuff here is about the ZOE, we LOVE this. Thank you again!!

yes its all from the Kangoo, i thought it was the same as the Zoe.

In reply to Daniel. VERY nice, thank you! Is this all Kangoo (Fluence ZE probably the same) as the labels show? There is a lot I do not recognize, such as the 3 prongs on the motor (ZOE has 4).

The capacitor has a fourth bolt on the top, so it is wired as a star, so indeed 230. The ZOE does not “use” 240 volt, the N pin should in theory never carry any current in 3 phase operation.

The inverter is located in the PEB module that sits between this BCB and the motor.

The R240 also uses the motor coil for charging.

The AC disconnect should be in the left part (see 3rd picture), for which I did not get pictures. But see https://canze.fisch.lu/charger-design/ and https://canze.fisch.lu/more-bcb-and-filter-pictures/ Fred swears though there are no relays in the filter module…….

I heard there was no problem. This was an exercise session to replace components. Looks like they “replaced” that second black power element.

So zoe uses 3×230 V not 400 V judging by the capacitor.
I thought zoe uses main transistor bridge witch drive the motor,to charge the battery ,not a seperate modul ?? That would explain why r240 only alow 22 kW charging,they use weaker modul.
What exactly doing this charging module?
where is the AC disconnect relay?

What was the problem in this case,why the dismantle the bcb

nice pictures 🙂
