Management Systems
Design Note 471

Introduction
In Li-Ion battery systems it is important to match the
charge condition of each cell to maximize pack performance and longevity. Cell life improves by avoiding both
deep discharge and overcharge, so typical systems strive
for operation between 20% and 80% states of charge
(SOC). Detection and correction of charge imbalances
assures that all cells track within the desired SOC window,
preventing premature aging of some cells that could
compromise the entire pack capacity. Highly accurate
measurements are required to determine SOC with Li-Ion
cells due to their exceptionally п¬‚at discharge characteristics, particularly with the lower voltage chemistries (see
example in Figure 1).
