BQ40Z50-R1: In-correct FCC

Phuoc Vo
Prodigy 100 points
Part Number: BQ40Z50-R1
Other Parts Discussed in Thread: BQSTUDIO

Hi,

We have a battery using BQ40Z50-R1 installed in our system for over 6 months, but the battery has never gone thru a complete charge/discharge cycle (Cycle count = 0) since our system operates with AC plugged in.

The FCC/RMC dropped to 3482mAh (design capacity is about 8100mAh), and so we have battery fault alarm since our system check the FCC for valid range of 6000mAh - 10000 mAh.

I removed the battery from the system and set it on the table, and starts logging the information with just  EV2300/BQStudio. The FCC recovered to about 7800mAh after about 5 hours (according to the log information).

I notice that before the battery recovered, the BatteryStatus(DSG) bit is 0, the ITStatus(REST) is also 0. The T_ambient is -296.5C. Max Error = 101%. T_sim = 24.2C

When the battery recovered,  the BatteryStatus(DSG) bit is 1, the ITStatus(REST) is also 1. The T_ambient is 18.6C. Max Error = 101%. T_sim = 17.9C

Please note that this battery still have Max Simulation Iterations set at 50, not 30. The battery was also not seal.

Please see attached files.

Thank you,

Phuoc

    Hi Batt,

    Is there any update for this issue ?

    Thanks,

    Phuoc

    FCC recovering is expected upon relaxation. Why did you change max simulation iterations? Those are internal parameters that are not expected to be changed. Please change it to defaults and then reset your gauge. Once you perform a learning cycle again they will be optimized.

    Also can you please upload your gg file or srec? It's much easier to analyze with that.

    Hi Batt,

    Please see gg file. Our Battery vendor set the max simulation iterations for us at 50, and now they recommend to 30. We have not made the change to this battery yet. We understand the FCC recovered after rest period, and a full learning cycle would also help to optimized.

    However, we are interested how did the FCC reduced to about half of its design capacity.

    Can you help to provide the possibilities ?

    Thank you,

    Phuoc

    Yes, it is possible that error can get accumulated over multiple cycles. This is especially true when batteries are not cycled fully. In your case I also saw data corruption. It seems that the gauge had data written to it. I saw your thread from Ryan by email. The indicator for that is the lifetime data last valid chg term cycle updating from 7 to 0. Now, this is not possible. That counter can only go up. This has also happened in a 10 hr span per the gauge and the second gg was exported 18 hours after. So, I’m suspecting that a shutdown had happened but that is not borne from lifetime data as well. The max error is 101%. This is also wrong because max error tops out at 100% after a reset. After the reset, the battery never relaxed or properly updated Qmax or Ra. A simple chg/relax/dsg/relax would recover the system.
