Tendo em conta a natureza finita das fontes de energia fóssil, o seu nocivo contributo para as
alterações climáticas e o período de crescente escassez em que estamos a entrar, esta
dissertação apresenta as energias renováveis e a mobilidade eléctrica como parte da solução
para uma nova era energética.
Ela inicia-se com uma secção sobre o panorama energético actual e os contributos dados pelas
descobertas decorrentes da primeira e segunda revolução industrial. Analisam-se depois a
evolução do veículo eléctrico, e das suas diferentes arquitecturas bem como dos sistemas de
armazenamento de energia e infra-estruturas e metodologias de carga. No capítulo seguinte
são apresentadas tecnologias de armazenamento de pequena e larga escala já existentes e em
fase de desenvolvimento, destas últimas são exploradas as mais promissoras que melhor
poderão ajudar na integração das energias renováveis e da mobilidade eléctrica no sistema
energético e no cotidiano da civilização.
No final é projectada e simulada uma bateria constituída por supercondensadores cuja função
é substituir a bateria de um pequeno veículo eléctrico. Neste projecto foram evidenciadas as
características desta alternativa e foram comprovadas as vantagens e as desvantagens deste
tipo de armazenamento de energia.
ABSTRACT: This dissertation presents renewable energy alternatives and electric mobility as part of the solution to a new energy age, given the finite characteristics of fossil energy sources, its harmful contribution to climate changes, and the increasingly scarcity period which we are now facing. The initial section is about the current energy scenario, and the changes that occurred since the discoveries made during the first and second industrial revolution. It has an analysis of the evolution of the electric vehicle, its different architectures and systems for energy storage and infrastructure, as well as the battery charge methodologies. The following chapter presents the existing and developing small and large scale storage technologies. The most promising ones are explored and that may help the integration of renewable energy, and electric mobility into daily civilization. In conclusion, a battery consisting of supercapacitors to replace a small electric vehicle's battery is designed and simulated. Alternative features were highlighted in this project, and the advantages and disadvantages of this type of energy storage have been proved.
