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.
Abstract The thermal response of the battery is one of the key factors affecting the performance and life span of lithium iron phosphate (LFP) batteries. A 3.2 V/10 Ah LFP aluminum-laminated batteries are chosen as the target of the present study.
From this analysis, one can conclude that the studied lithium iron based battery cells are not recommended to be charged at high current rates. This phenomenon affects the viability of ultra-fast charging systems. Finally, a cycle life model has been developed, which is able to predict the battery cycleability accurately. 1. Introduction
Fig. 14 shows that the cycle life of a battery is strongly dependent on the applied charging current rate. The cycle life of the battery decreases from 2950 cycles to just 414 at 10 It. From this analysis, one can conclude that the studied lithium-ion battery cells are not recommended to be charged at high current rates.
Highlights A three-dimensional thermal simulation model for lithium iron phosphate battery is developed. Thermal behaviors of different tab configurations on lithium iron phosphate battery are considered in this model. The relationship among the total heat generation rate, discharge rate and the DOD inside the battery is established.
This battery is designed for high power density, its typical discharge rates are 3C and 5C. Thus Fig. 5provides the infrared imagery results and simulation results at the discharge end of 3C and 5C at room temperature with natural cooling condition.
