Experimental Validation of the Aging Model of Lithium-Ion Batteries Regardless of Deterioration Conditions

This work validates, experimentally, the conformity of the electrical aging model for LiFeP04 and NMC type lithium cells by taking into account the effects of temperature, current and internal resistance on its yield. If necessary, modifications will be made to the aging model based on the experimental results. To carry out this work, the following structure was used. First, a literature review outlining the chemical principles and aging mechanisms of lithium batteries. Next, the battery aging model and everything that makes it up will be analyzed. In order to collect experimental data, lithium batteries and a test protocol will be put to the test bench. Validation will be done by comparing the simulation results of the proposed model with the experimental data obtained. This model will then be compared to another aging simulation technique. To conclude, the differences between the two simulation methods and the experiment will be analyzed to establish the validity and advantages of the proposed model.
