The present research focuses on the analysis of the forecast of the condition and the management of the life cycle of the lithium-ion batteries, located inside the B787-8 passenger aircraft to improve the maintenance management strategy of the aircraft fleet of Avianca Peru Airline. The maintenance of lithium-ion batteries used as a reliable and last resort power source during in-flight events was evaluated. For the research, some health indicator curves were taken such as: voltage, temperature and capacity, the latter being the one that showed linear wear and continuous degradation behavior during the life cycle of the battery which was used. to determine the diagnosis of the state of health and the prognosis of the remaining useful life. To meet the objectives of the research, a supervised machine learning tool suitable for solving regression problems in non-parametric data called Gaussian Process Regression was used. This architecture of Artificial Intelligence provided predictive values for decision making in Maintenance Management. The database of lithium-ion batteries B0005, published from the NASA repository (2007) of the Ames Research Center, Moffet Field, was used for the development of the research because it contains the same design and structure technology used. in the fleet of B787-8 aircraft of Avianca Peru Airline. Finally, the project and implementation were economically analyzed and a profit of $841,840 was obtained. On the other hand, the return on investment and the return on capital period were 439% and 6 months respectively, which made the project viable. Based on this research and the model obtained, new maintenance strategies based on condition were proposed for lithium-ion batteries and other aircraft components that suffer atypical wear and tear and reduced performance due to the dynamism of their operation.
