Diseño y construcción de un sistema de gestión de energía para aplicaciones de asistencia a la movilidad en extremidades inferiores

Abstract

This degree work details the construction of an energy management system that will support the project developed by the University of Cuenca, called "Prototype of usable exoskeleton on lower extremities". The proposed system will be responsible for supplying the necessary energy for the components of the exoskeleton, such as: motors, sensors, microcontrollers, etc. The energy management system will consist of 3 main parts: an energy source formed by a battery bank created through the union of 8 cells of lithium ion whose capacity was chosen based on a of the energy that will be consumed by the system, in order to obtain an autonomy of 90 minutes; an integrated circuit responsible for monitoring and taking measurements of cell voltages and temperatures through commands sent by a microcontroller, and a charger, external to the system, charged responsible for recharging the cells which make up the energy source. In order to protect the lithium ion cells, the constructive aspects of a container made of a flexible and resistant material are included, in such a way that the cells are protected against the weather. Finally, due to the weight of the batteries, a backpack will be included as a container for the components of the source and the Management System, in order to improve the portability of the project.
