Title: Battery Management System -> how to test its functionality?
Post by: Just on September 21, 2012, 12:28:20 PM

Hello All,

I found several LiFePo4 cells in my battery pack, which was discharged to 0V. Should it be a BMS malfunction or cell problem? How to test?

When then I charged the discharged cells with a small current (about 0.1V), they were recovered from 0V to their nominal 3.3V.

Is it possible that BMS shorts the cells during a discharge?

Thank you!

Its a BMS problem. Do you have a Cycle Analyst or a Watts Up meter?
