Diseño y construcción de un módulo programable en ciclos para descarga y carga automáticas para baterías híbridas de Níquel metal.

Abstract

This project was carried out through the design of a discharge and charge module for the respective nickel metal hybrid batteries of Instituto Universitario Vida Nueva. With the purpose of verifying the electrical behavior of the hybrid batteries in their charge and discharge phase according to their operation, with the design that was carried out in the PROTEUS application, we will proceed to select the respective elements that will be used for the respective module. The goal of this project was to develop a system to control the power and temperature values of hybrid batteries during the charge and discharge processes. To achieve this goal, the Arduino system was used to monitor and control both the potential and temperature of a single battery during the charge and discharge processes. In this way, it was possible to observe the process that the module would carry out on the test bench. Finally, the discharge and charge circuit of the hybrid batteries was built, this through a printing on photo paper which was passed to a Bakelite which was immersed in ferric chloride to mark the channels of the circuit that will allow the control of the module, the programming for the module was developed in Arduino which was programmed on the board through a computer which allows charging high voltaje battery modules individually with a constant energy that is set at the start of the test. This current can be set between 0.7 A and 2.5 A for modules up to 20 volts.
