Analysis of the reliability and failure mode of lithium iron phosphate batteries is essential to ensure the cells quality and safety of use. For this purpose, the paper built a model of battery performance degradation based on charge–discharge characteristics of lithium iron phosphate batteries .
Charge–discharge cycle life test Ninety-six 18650-type lithium iron phosphate batteries were put through the charge–discharge life cycle test, using a lithium iron battery life cycle tester with a rated capacity of 1450 mA h, 3.2 V nominal voltage, in accordance with industry rules.
For this purpose, the paper built a model of battery performance degradation based on charge–discharge characteristics of lithium iron phosphate batteries . The model was applied successfully to predict the residual service life of a hybrid electrical bus.
Part of the charge–discharge cycle curve of lithium iron battery. According to the testers record, ninety-six battery samples failed (when the battery capacity is less than 1100 mA h). The cycles are listed in Table 2 in increasing order, equivalent to the full life cycle test.
Li-ion battery failures. A critical step in this process is the understanding of the root cause for failures so that practices and procedures can be implemented to prevent future events.
