Metodología técnico-económica para remanufactura de baterías Ni-MH en vehículos híbridos y eléctricos

Abstract

CONDITION FOR PUBLICATION OF PROJECT. The project developed a remanufacturing methodology aimed at extending the lifespan of NiMH battery modules used in hybrid vehicles, focusing on sustainability and reducing environmental impacts. The objective was to design a technical procedure that would guarantee safety and reliability, hypothesizing that the application of diagnostic, classification, and reconditioning processes would restore the modules' functionality. The justification was based on the need to reduce hybrid vehicle maintenance costs and efficiently utilize existing resources. The work included battery collection and disassembly, charge and discharge testing, and compliance with safety standards. The results demonstrated that a significant percentage of modules recovered acceptable voltage, internal resistance, and capacity parameters, validating the proposed methodology. Finally, it was concluded that remanufacturing constituted a technically and environmentally viable alternative that contributes to sustainability in the automotive sector. Keywords: SOC, SOC, internal resistance, charge and discharge.
