Diseño e implementación de un poste de recarga de baterías para un prototipo de vehículo híbrido en la Escuela de Ingeniería Automotriz.

Abstract

This paper describes the study and development procedure for the design and implementation of a battery recharge post for a hybrid vehicle prototype in the School of Automotive Engineering, for this the analysis and study of the best technology was carried out available for the realization of the project, in its different stages. The parameters were defined most important to consider in the design of the loader, the realization of the project is based In an experimental and heuristic methodology (engineering method), the use of electronic power elements MOSFET type, sensors for the acquisition of data and the use of microcontrollers, all are combined in a prototype battery charger of Nickel Metal Hydride (Ni-MH). The prototype has 3 stages controlled by a free programming hardware and software platform, it was monitored in addition to the parameters most important of the NiMH battery charging process to finish the operation in case of any risk situation through GSM text messages. A prototype that raised the amount of battery charge from 28 cells to the desired voltage with a current that progressively decreased according to the state of charge of the battery, this with the intention of keeping the temperature within the previously safe ranges studied, and in a time of 2.29 hours. The addition of signal filters and sensors is recommended of temperature to increase the load ratio.
