Abstract(s)
Os combustíveis fósseis encontram-se cada vez mais limitados no mundo atual e, tendo em conta a inevitável adesão em massa aos veículos elétricos/ híbridos, é necessário procurar soluções nas energias limpas para abastecer estes veículos. Neste contexto, este trabalho estudou a viabilidade técnico-económica de sistemas de produção de energias limpas para abastecimento dos veículos elétricos. São analisados vários cenários que representam os quilómetros realizados diariamente pelo(s) veículo(s) elétrico(s). Para além do estudo técnico é realizado o estudo da viabilidade económica de cada cenário. A realização deste trabalho exigiu compreender os conceitos e tecnologias associadas à energia solar fotovoltaica e ao armazenamento de energia. A seleção do veículo elétrico é feita consoante o cenário, a sua autonomia e a sua eficiência, não sendo escolhido nem o mais eficiente nem o menos eficiente, para tornar este estudo o mais próximo possível da realidade. São calculadas as necessidades energéticas para cada cenário consoante o veículo elétrico selecionado. Após o levantamento das necessidades energéticas, é elaborado o estudo técnico, nomeadamente, a produção de energia pelos módulos fotovoltaicos. A análise efetuada para os diversos casos de estudo contou com o apoio do software PVGIS. Feita a seleção dos equipamentos, segue-se o estudo da viabilidade económica para cada cenário, sendo que os cash flows são calculados consoante a energia armazenada pela bateria em cada dia (representam o capital poupado em energia elétrica em relação ao carregamento doméstico do veículo elétrico sem a existência de um sistema fotovoltaico), a manutenção dos painéis fotovoltaicos e a manutenção da bateria.
Fossil fuels are increasingly limited in today's world and, considering the inevitable mass adherence to electric / hybrid vehicles, it is necessary to seek solutions in clean energy to fuel these vehicles. In this context, this document studies the technical and economic viability of clean energy production systems for fuel electric vehicles. Several scenarios that represent the kilometers traveled daily by the electric vehicle (s) are analyzed. In addition to the technical study, the study of the economic viability of each scenario is carried out. The realization of this document required understanding the concepts and technologies associated with solar photovoltaic energy and energy storage. The selection of the electric vehicle is made according to the scenario, its autonomy and its efficiency, neither the most efficient nor the least efficient being chosen to make this study as close to reality as possible. The energy requirements for each scenario are calculated depending on the electric vehicle selected. After collect the energy needs, the technical study is prepared, namely, the energy production by the PV modules. The analysis carried out for the different case studies had the support of the PVGIS software. Once the equipment is selected, the economic feasibility study for each scenario follows, with cash flows being calculated according to the energy stored by the battery on each day (they represent the capital saved in electricity in relation to the domestic charging of the electric vehicle without the existence of a photovoltaic system), the maintenance of photovoltaic panels and the maintenance of the battery.
