This range encompasses both low and high temperature thresholds. Deviating from this range can have adverse effects on battery capacity, efficiency, and even safety. The recommended low-temperature threshold for LiFePO4 batteries typically ranges between -20°C and -10°C.
On the other hand, the high-temperature threshold for LiFePO4 batteries typically falls between 45°C and 60°C. Operating the battery beyond this threshold can result in accelerated self-discharge rates, reduced capacity, and increased risk of safety hazards such as thermal runaway.
To investigate the cycle life capabilities of lithium iron phosphate based battery cells during fast charging, cycle life tests have been carried out at different constant charge current rates. The experimental analysis indicates that the cycle life of the battery degrades the more the charge current rate increases.
In , , the charge & discharge resistances of lithium nickel cobalt oxide battery cells have been investigated at various working temperatures (40 °C, 50 °C, 60 °C and 70 °C). The authors have applied the normal Hybrid Pulse Power Characterization (HPPC) test at 60% and 80% SoC during the cycle life of the battery.
Furthermore, during the cycling test, the surface battery temperature of the battery cells has been monitored by using thermal sensors (Type K) in the middle of the battery cells. From the experimental results, one can observe that the high surface temperature at 10 It and 15 It (about 55 °C).
According to the performed analysis, a life cycle model has been extracted. However, one should pay attention that the maximum temperature for the proposed battery chemistry is 40 °C and 55 °C during charge and discharge, respectively. The presented analysis exceeds this envelope and cannot have occurred in reality.
