Desarrollo de un método de inspección utilizando termografía como herramienta para mantenimiento predictivo de la batería de alto voltaje de NI-MH de vehículo hibrido tipo sedán

Abstract

This study aims to develop a non-destructive inspection method using infrared thermography for predictive maintenance of high-voltage batteries in hybrid sedan vehicles. Its objective is to guarantee the useful life of the batteries, reducing unnecessary replacements and minimising the environmental impact. The implementation of the thermographic test is based on three methods (measurement, comparative and analytical) for the acquisition of thermal signatures and battery functional data (voltage, current and state of charge). The results, processed with statistical software, demonstrate the effectiveness of infrared thermography as a tool for maintaining and guaranteeing the useful life of these batteries.
