Nice

This should be fine. Note also, the order of the cell supervision circuit and cell module are not swapped.

just be careful with the installation. Once the system detects you have opened the HV battery, the contactor will be opened and this will most likely require EOS tester to close the contactor.

No calibration needed. Just follow the procedure of installing the replacement sensor and you should be good.

use this part number "61 27 8 849 422". A google search of this will show you what it looks like.

Yes, you can change it.There is a procedure you have to follow to do this with BMW repair kit that includes the sensor. You can get the procedure from the ISTA you are using under " Repair Manuals and Technical Data / 61 General vehicle electrical system / 61 27 High-voltage battery unit indivi...

I think only cell module 5 is okay. The temperature sensor reading should be around 80kΩ to 92Ω but less than 100Ω for this particular sensors and any anything above it indicates a failure of the sensor. Module 2 (T2 is bad), Module 3 (T2 & T3 bad), module 4 (T3 is bad). Did you check this with ...

Have been able to get the "exact" NTC used in the battery modules based on Deutronics HV charger manual. The NTCs are of 2 variant 100k/4.4 and 10k/3.4

Thanks, will surely have a look at it. I tested a 3950 100k ohms NTC and seems to "work" as I got a a very close ambient temperature reading. I've got a very rough approximation when working out ADC readings vs temperature. Check lines 92 - 101 here: https://github.com/mjc-506/bmsSerial/bl...

Thank you very much. The sensor I do require is the one directly on the batteries

I need help with information on the type of temperature sensors used in BMW battery modules. I have couple of failed ones and needs to replace them but could not get any leads on the type and value.

Thanks
