We designed 2 years ago a LiFePO4 battery pack (10Ah/3.2V/12 cell). We did several third party tests (CE, FCC, UL, UN tests) on it and got the correct approvals.
However, under some occasions we noticed that the SOC indication failed when we were using the battery pack.
We did already some optimizations (with help from TI), but the SOC still fails in some cases: calculated rem cap values of 220Ah for an individual cell (real value = 10Ah). In those cases the RSOC makes the strangest jumps (from 100% till 0% within a second).
My questions:
- Will it be possible to tweak the settings so RSOC will work correctly for this battery pack?
- What accuracy of RSOC can we expect with the bq78PL114?
- Does TI offer a (paid) service to optimize the bq78PL114 for our battery pack?
We must find a solution urgently. Hope to get an answer soon!
Thank you.
