    Improving the autonomy of a Mid-Drive motor electric bicycle based on system efficiency maps and its performance
    (MDPI, 2021) Arango López, Iván Dario; López Zapata, Carlos Eduardo; Ceren Correa, Alejandro; López Zapata, Carlos Eduardo
    Around the world, the e-bike has evolved from a recreational and sports object to an increasingly used means of transportation. Due to this, improving aspects such as range and energy efficiency has become very relevant. This article presents experimental models for the components’ efficiency of a mid-drive motor e-bike (charger; battery; and controller, motor, and reduction gears subsystem), and integrates them with previously elaborated models for the chain transmission system, thus generating an overall efficiency map of the e-bike. The range of the electric bicycle is analyzed by integrating the efficiency map of the system and its performance mathematical model, aiming to determine the per unit of distance battery energy consumption. The above-mentioned calculations are applied to develop a management strategy that can determine the optimal assistance level and chain transmission ratio, maximizing range and leaving speed unaffected. The driving strategy was compared against other driving techniques using computational analysis, this allowed for the observation of the proposed strategy improving the system’s range by reducing the battery energy consumption.

    Integrated design and development of complex systems under a PLM approach: a sustainable transportation system case study
    (2012) Osorio Gómez, Gilberto; Mejía Gutiérrez, Ricardo; Universidad EAFIT. Departamento de Ingeniería de Diseño; Gilberto Osorio (gosoriog@eafit.edu.co); Ricardo Mejia (rmejiag@eafit.edu.co); Ingeniería de Diseño (GRID)
    The materialization of design projects has demonstrated to be a key factor for the evaluation of new ideas -- In this field, the Department of Product Design Engineering from EAFIT University has been pioneer in Colombia -- In order to take this process to a new level, an integrated approach has been proposed oriented to the design and development of sustainable transport value added products, particularly in the field of electric mobility, where transport systems complexity is combined with the need of developing sustainable products, together with the use of technologies in the area of Product Lifecycle Management (PLM) -- It is presented the adopted methodology for development of this kind of projects at academic level, detailing main activities and tools, and describing a successful case study for the design of a functional prototype of an electric bicycle, in order to demonstrate the findings and experiences obtained in this kind of implementations that, in the future, will be translated into trained engineers on advanced product development, as well as to raise industrial awareness in the subject
