PRODUCTION DATA.
When Fast Resistance Scaling is enabled by setting the [FConvEn] bit in Pack Configuration B, the algorithm improves accuracy at the end of discharge. The RemainingCapacity() and StateOfCharge() should smoothly converge to 0. The algorithm starts convergence improvements when cell voltage goes below (Terminate Voltage + Term V Delta) or StateofCharge() goes below Fast Scale Start SOC. For most applications, the default value of Term V Delta and Fast Scale Start SOC are recommended. Also TI recommends keeping (Terminate Voltage + Term V Delta) below 3.6 V for most battery applications.
