Abstract(s)
Entre a grande diversidade de baterias existentes tecnologicamente maduras, as baterias de
Iões de Lítio (Li-ion) tornaram-se populares devido à sua longevidade, alta densidade de
energia, alta eficiência e não sofrerem de efeito de memória. Este trabalho tem como objetivo
desenvolver novos métodos de carregamento que incluam balanceamento para sistemas de
baterias de Iões de Lítio. Este pode ser dividido em duas fases distintas: a primeira fase tem
que ver com o desenvolvimento de toda a plataforma, a segunda fase refere-se ao
desenvolvimento de novos algoritmos.
De forma resumida a primeira fase teve como objetivo desenvolver todo o hardware e software
necessários para a criação de uma plataforma versátil e intuitiva onde fosse possível criar
algoritmos de carregamento e balanceamento de forma eficiente. O sistema principal do
hardware implementado trata-se do Battery Management System (BMS), responsável por toda
a monitorização do pack de baterias utilizado.
A segunda fase do trabalho focou-se no desenvolvimento de novos algoritmos inteligentes de
carregamento que incluam o balanceamento. A opção por esta abordagem refere-se ao facto
de ser essencial controlar os desequilíbrios entre células durante o carregamento, resultando
numa maior eficiência do sistema de armazenamento. Os resultados obtidos são comparados
com os algoritmos tradicionais existentes na literatura.
Among the wide diversity of existing technologically mature batteries, lithium-ion (Li-ion) batteries have become popular because of their longevity, high energy density, high efficiency and lack of memory effect. This work aims to develop new charging methods that include balancing for lithium-ion battery systems. This can be divided into two distinct phases: the first phase has to do with the development of the entire platform; the second phase refers to the development of new algorithms. Briefly in the first phase was developed all the hardware and software required to create a versatile and intuitive platform where it was possible to create charging and balancing algorithms. The main hardware implemented system is the Battery Management System (BMS), responsible for all the monitoring of the battery pack used. The second phase of the work focused on developing new intelligent charging algorithms that include balancing. The option for this approach has to do with the fact that it is essential to control the imbalances between cells during charging, resulting in greater efficiency of the storage system. The obtained results are compared with the traditional algorithms present in the literature.
