Abstract(s)
O presente projeto foi desenvolvido no âmbito da unidade curricular de Tese/Dissertação
(TEDI) do Mestrado em Engenharia Eletrotécnica e de Computadores -
Sistemas e Planeamento Industrial, do Instituto Superior de Engenharia do Porto
(ISEP), em colaboração com a Efacec Electric Mobility, S.A. A dissertação centra-se
no projeto e desenvolvimento de software para um carregador Wallbox de corrente
contínua (DC) para veículos elétricos, baseado na framework modular e de código
aberto EVerest.
A crescente adoção de veículos elétricos exige o desenvolvimento de infraestruturas
de carregamento eficientes, flexíveis e interoperáveis. Os carregadores Wallbox
DC surgem como uma solução vantajosa, combinando carregamentos rápidos com
instalação flexível. A utilização de frameworks de código aberto, como o EVerest,
oferece modularidade, escalabilidade e redução dos custos de desenvolvimento.
O principal objetivo desta dissertação consiste na criação de uma solução funcional
e modular que permita a implementação de um sistema de carregamento DC
eficiente, recorrendo ao padrão de carregamento CCS. Procurou-se garantir a compatibilidade
com os principais padrões da indústria, nomeadamente os protocolos
de comunicação veículo-carregador DIN SPEC 70121, ISO 15118-2 e ISO 15118-
20, e protocolos de comunicação entre carregador e sistemas de gestão centralizados
OCPP 1.6 e OCPP 2.0.1.
O trabalho desenvolvido validou a viabilidade da framework EVerest como base
para o desenvolvimento de soluções comerciais de carregamento DC. A abordagem
modular adotada facilita futuras atualizações e a integração de novas funcionalidades,
contribuindo para o avanço da mobilidade elétrica sustentável.
This project was developed within the scope of the Thesis/Dissertation (TEDI) curricular unit of the Master’s in Electrical and Computer Engineering - Industrial Systems and Planning, at Instituto Superior de Engenharia do Porto (ISEP), in collaboration with Efacec Electric Mobility, S.A. The dissertation focuses on the design and software development for a direct current (DC) Wallbox charger for electric vehicles, based on the modular and open-source EVerest framework. The growing adoption of electric vehicles requires the development of efficient, flexible, and interoperable charging infrastructures. DC Wallbox chargers emerge as an advantageous solution, combining fast charging with flexible installation. The use of open-source frameworks, such as EVerest, provides modularity, scalability, and reduced development costs. The main objective of this dissertation is the creation of a functional and modular solution that enables the implementation of an efficient DC charging system, using the CCS charging standard. The aim was to ensure compatibility with the main industry standards, namely the vehicle-to-charger communication protocols DIN SPEC 70121, ISO 15118-2 and ISO 15118-20, as well as the protocols for communication between the charger and centralized management systems, OCPP 1.6 and OCPP 2.0.1. The work carried out validated the feasibility of the EVerest framework as a basis for the development of commercial DC charging solutions. The modular approach adopted facilitates future updates and the integration of new functionalities, contributing to the advancement of sustainable electric mobility.
