Item Estudo de métodos para o dimensionamento do sistema de armazenamento de energia de um veículo elétrico tipo fórmula(2024-03-05) Alves, Adriany Fabrícia Silva; Araújo, Marcel Ayres de; http://lattes.cnpq.br/0669410110930611; http://lattes.cnpq.br/3796261196279460Faced with the need to reduce carbon dioxide emissions and increasingly reduce the fleet of gasoline vehicles, among other petroleum derivatives, in an attempt to mitigate the damage caused by pollution to the environment, the implementation of Electric Vehicles (EVs). They are a general concept of means of transport that takes advantage of the electric motor as the traction actuator, and one of the main types of EVs are those that use batteries as an energy storage system, also known as BEVs (Battery Electric Vehicles). BEVs are considered a solution that has the potential to mitigate greenhouse gas emissions and reduce the use of oil in the transport sector, avoiding energy crises. EVs present a technological evolution of transforming electrical energy into movement, which consequently has increased interest in electric propulsion for automobiles in recent years. They are designed to be competitive in terms of cost-benefit with conventional vehicles in the coming years. Given its importance, this work addresses a significant context of growth in the battery electric vehicle fleet in Brazil, from its technological characteristics, challenges, potential problems and benefits, through its energy transmission system, and its operating dynamics. After the theoretical foundations and all bibliographical references researched, the main objective is to study the sizing of this storage system aimed at BEVs applied to a formula-type EV. As a result, this study developed a detailed methodology for sizing formula-type vehicle power, force and energy, based on an in-depth analysis of the electric vehicle routing problem, exploring its different variants and possible solution approaches. Next, proceed to sizing the battery pack using a series-parallel configuration used to supply the ordinary power. Finally, the battery selection was carried out through MCDA statistical analysis using the AHP-Gaussian and AHP-Gaussian with Pearson Correlation method, resulting in the choice of the SLPBA096235 cell as the discovered technology, which declared nominal values in agreement and compatible with the main specificities related to formula-type EVs for the scaled system.Item Impactos, oportunidades e perspectivas para a implementação da eletrificação dos meios de transporte no Brasil(2024-03-07) Siqueira, Breno Filipe Andrade Lima de; Neto, Fernando Gonçalves de Almeida; http://lattes.cnpq.br/0473869396914603; https://lattes.cnpq.br/1256466512019055Technological advancements associated with mobility, growing concerns regarding energy resource scarcity, studies and perspectives on global climate change, and discussions related to environmental preservation have underscored the need for modernizing transportation methods that align with less environmentally aggressive actions, paving the way for electromobility technologies. In this context, this paper addresses the importance of electric mobility as a response to the challenges of climate change and the need to reduce greenhouse gas emissions. Additionally, it discusses the impacts, opportunities, and prospects for implementing the electrification of transportation in Brazil, from the perspective of the impacts of guiding public policies for its implementation, including tax incentives, subsidies, regulations, and standards. Methodologically, the study was based on a qualitative research approach, conducted through consulting academic studies, technical reports, statistical data, public policies, and governmental documents related to the electrification of transportation. The results reveal that Brazil is moving at a slower pace in regulating electric mobility compared to countries such as China, the United States, and countries in the European Union, but it remains a niche with great potential for expansion and consolidation of electromobility- associated technologies. Based on the study conducted, this paper highlights practical implications and possible future directions for the adoption and promotion of electric mobility, considering the experiences of countries that are more advanced in adopting electric mobility as an alternative to combustion vehicles.Item Estudo de modelo e controle vetorial orientado pelo fluxo estatórico de motor de indução trifásico para propulsão de veículos elétricos(2020-11-06) Azevedo, Pedro Paulo Oliveira Costa de; Silva, Italo Roger Ferreira Moreno Pinheiro da; http://lattes.cnpq.br/7618299953557040The speed control of three-phase induction motors is essential for the operation of electric vehicles. Therefore, the study of the machine mathematical model for the development of simpler and more effcient methods for the control of motor parameters is important for technological development and reduction in the costs of building electric vehicles. In this project, the study of the mathematical model for the analysis of the behavior of an electric induction motor was carried out and a eld oriented control strategy was developed that uses mathematical transformations and changes of reference of the measurable quantities in an induction machine and, from this strategy, a simulation was developed. The transient and permanent response of the electromagnetic fux, conjugate, speed and electric currents obtained in the simulated environment show the reaction of the model of the induction machine with the control proposed in this work, accelerating from inertia to near to the rated speed and the elimination of the disturbance caused by the insertion of the rated mechanical torque on the motor shaft. Thus, the simulation results presented validate the theoretical considerations and show the effectiveness of the proposed control strategy, enabling its use for future studies by the UFEPE-UACSA formula SAE team.
