Many warning signs may occur when a lithium iron phosphate battery is overcharged. These signs include: These signs are not exclusive to overcharging and may also indicate other issues. Additionally, overcharging can occur even without exhibiting these signs. Therefore, a BMS is the best way to detect and prevent overcharging.
For example, the full-charge voltage of a monolithic lithium iron phosphate cell is 3.65V. When the charge exceeds 3.65V, it is overcharged. What will happen when a lithium-ion polymer (LiPo) battery is overcharged? Overcharging a battery cell will cause permanent damage to the cell.
Driven by this, an experimental investigation was carried out to study the characteristics of TR and gas venting behaviors in commercial lithium iron phosphate (LFP) batteries that were induced by overcharging under different rates.
Discharge the cells enough to decrease the cell voltage to a normal range, such as 3.2V for lithium-iron phosphate batteries. If the battery cells have a pressure safety valve, open it. Not all cells have a safety valve. And the steps to release it can vary based on the battery.
To verify the performance of the model, the test set data of the 6 Ah lithium iron phosphate battery was used to validate the model and calculate the performance metrics of the model based on the confusion matrix ( Fig. 12) as shown in Table 3. Fig. 12. Model confusion matrix. Table 3. Model evaluation parameter table.
Ohsaki et al. (2005) concluded that the process of overcharge was typically divided into several stages, and the occurrence of TR was mainly due to violent reactions between deposited lithium and electrolyte at high temperature. Additionally, severe side reactions inside the battery can also result in the generation of a substantial amount of heat.
