Hi i have a Transit Connect electric and one half of the batterypack wont connect/engage does anyone know soething about this cars anymore? i am suspecting the BMS but no fault code or anything is showing, ESS1 stays in "contactor state" as first picture shows for a while then it disconnects, ESS2 shows "xxxxC400" for just a second then it changes to xxxxC600 and contactor voltage shows up and the car is running on one half..

Thanks Robin

It looks like that battery is also on Alibaba.


There may be more negotiating in purchasing from Alibaba than AliExpress. However, it may be a benefit for larger bulk orders.

Hello everyone
New problem, now with the cooling system (I didn’t find a topic, so I’m asking here, sorry): last time the radiator’s fans working almost constantly, but the temperature on the dashboard is normal and the radiator is cold. TVBEV fixes 70 degrees; we can hear that the pump is working. Probably clogged, need to find where.
But I have another question: TSVEV can show pump RPM (look the picture): did anyone pay attention to what pump speed you have?
I always have 0.
Thanks

Ok, I went out driving today.

The dashboard temperature gauge was pegged at 50%, and did not budge.

When driving, or stopping, I couldn't discern any fan or pump noises. I don't drive very aggressively, and it was a cool afternoon.

However, as soon as I release the brakes, I hear the brake vacuum pump operating for a few seconds, then it stops.

As mentioned above, when charging at 110V, I hear either a fan or pump running about 75% of the time.

I still need to try to get the diagnostic software running.

Thank you, everything is exactly the same, with the exception of the radiator fans: they turning on almost immediately. However, now less often. 100% the pipe is stucked somewhere. No time to look. Bad, that I can't see which RPM the pump is spining at.
Can I help you with diagnostic software problem?

Thanks, everything is fine. Ford runs (y) , there are some problems with engine cooling, but now is winter... :)We bought a second Ford, now trying to restore the battery, but… there are no good batteries, boards, etc. By the way, here we found a programmer, who read a flash from one BMS board and overwrote it into another, i.e. made a clone of the desired board, so it's possible.(y)
