you replaced the FET on the high side SmartBMS with resistors?
see Fig. 2

please explain further

you followed the AN#16 from O2Micro? 'EFETC-Out' on high side SmartBMS > optocoupler > 'EFETC-In' on the low side SmartBMS ?
I'm just busy looking for the source I have almost determined.Output EFETC can not serve as a source of signal off the charge. I'll be taking a signal from the point of CG, handle and serve on the transistor optocoupler.

looks like an interresting and busy site - what about this 'monitoring configurator' program - is it made for the OZ?
Colleague Mevial wrote the console program for Linux to query information from the BMS, download and dump configurator http://mevial.ru/oz/. ty program can be found in the theme of the first link or here http://translate.google.com/translate?h ... 3msg156763
The program eliminates the need for expensive cable for $ 100 http://www.paintyourdragon.com/?p=43
