Conferences > 2015 IEEE Vehicle Power and P... Commercial lithium-ion phosphate batteries were tested to investigate their responses to overcharge and overdischarge conditions. During overcharge tests, cells were charged at 1C successively until certain visual symptom such as gas release or vent burst occurred.
Large-capacity lithium iron phosphate (LFP) batteries are widely used in electric bicycles. However, while crucial, thermal runaway (TR) behaviors under overcharge conditions have rarely been studied, leading to frequent fire accidents.
Liu et al. found that the cell thermal stability decreased gradually as lithium-ion batteries aged with slight overcharge cycling. Compared with slight overcharge, deep overcharge can make lithium-ion batteries complete failure and cause thermal runaway, resulting severe safety hazards such as fire and explosion.
This paper investigates the entire overdischarge process of large-format lithium-ion batteries by discharging the cell to −100% state of charge (SOC). A significant voltage platform is observed at approximately −12% SOC and ISCr is detected after the cell is overdischarged when passing the platform.
The proposed approach is suitable for over-discharge diagnosis and predication in electric vehicle applications. Lithium (Li)-ion batteries have become one of the most popular power sources for electric vehicles (EVs) due to their high energy, power density and long service life.
In addition to the influence of the charging method, Wang et al. compared the thermal runaway behavior of the cell with different cathode materials, and found that the ternary batteries had better overcharge tolerance performance, while lithium iron phosphate batteries had a lighter response to overcharge.
