3. Why is over-discharge protection critical for lithium batteries, and how does a PCM manage this? Over-discharge protection is critical because it prevents the battery voltage from dropping below a safe threshold, which can lead to a significant loss of capacity and damage the battery''s internal structure.
Avoiding full discharge also plays a pivotal role in preventing this damaging scenario. Recovering an over-discharged LiFePO4 battery is possible to some extent by using a parallel charging board to connect it to a standard 3.2V LiFePO4 battery. However, this method only works if the battery''s voltage hovers around 3V post-over-discharge.
