5. Conclusion An electro-thermal cycle life model is develop by implementing capacity fading effect in electro-thermal model of cylindrical lithium ion battery, this model is able to simulate the discharging performance during different discharge cycles, predicting battery temperature, as well as predicting capacity loss at different cycle number.
Low-temperature environments have a greater impact on the performance of LiFePO4 batteries than high temperatures. Judging from the current market situation, lithium iron phosphate batteries operate from below -20 °C to -40 °C, and their lifespan is significantly reduced, with a cycle life of 300 times. Part 5. How to test LiFePO4 cycle life?
In this study, an accelerated cycle life experiment is conducted on an 8-cell LiFePO 4 battery. Eight thermocouples were placed internally and externally at selected points to measure the internal and external temperatures within the battery module.
Generally, slower charging rates are preferable as they help extend battery life. The depth of discharge significantly influences the longevity of LiFePO4 batteries. A lower depth of discharge can greatly enhance the battery's lifespan, while deeper discharges can shorten it. Avoiding full discharges to very low voltages is advisable.
When the cycle continues, the discharge capacity of the LiFePO 4 battery gradually decreased, the attenuation of battery capacity by the depth of discharge is more and more obvious. The right capacity fading rate curve shows that battery capacity decay rate remained the same at the beginning of the cycle.
2. Discharge depth The depth of discharge is the main factor affecting the LiFePO4 battery life. The higher the depth of discharge, the shorter the life of the lithium iron phosphate battery. In other words, as long as the depth of discharge is reduced, the service life of lithium iron phosphate batteries can be greatly extended.
