  Filtro de Kalman aplicado à estimação do Estado de Carga (SoC) e do Estado de Saúde (SoH) de baterias em sistemas de armazenamento de energia

  Diuary Gonçalves

  ResumoAbstract (Portuguese)

  Este minicurso apresenta o Filtro de Kalman como ferramenta para estimar o Estado de Carga (SoC) e o Estado de Saúde (SoH) de baterias, grandezas essenciais para a operação segura, eficiente e duradoura de sistemas de armazenamento conectados à rede elétrica.

  A atividade parte da importância do monitoramento de baterias em sistemas BESS, veículos elétricos e microrredes e discute as limitações de métodos tradicionais, como a contagem de Coulomb e a relação tensão de circuito aberto–SoC. Em seguida, apresenta a modelagem de baterias por circuito elétrico equivalente e a formulação do problema em espaço de estados.

  São trabalhados os fundamentos do Filtro de Kalman e de suas extensões não lineares, como o Filtro de Kalman Estendido (EKF) e o Unscented (UKF), com foco no ajuste das matrizes de covariância e na robustez frente a ruídos e incertezas do modelo. O minicurso também aborda a estimação do SoH, considerando a perda de capacidade e o aumento da resistência interna ao longo da vida útil.

  Exemplos práticos e simulações conectam a teoria à implementação em sistemas de gerenciamento de baterias (BMS).

  Inteligência Artificial aplicada à estimação de estados e ao balanceamento de células em baterias para sistemas de armazenamento de energia

  Ediward Amaral Carelli

  ResumoAbstract (Portuguese)

  Este minicurso apresenta técnicas de Inteligência Artificial aplicadas a dois desafios centrais do gerenciamento de baterias: a estimação de estados e o balanceamento de células, ambos decisivos para o desempenho, a segurança e a vida útil de sistemas de armazenamento integrados à rede elétrica.

  Na primeira parte, são abordadas abordagens orientadas a dados para estimar o Estado de Carga (SoC), o Estado de Saúde (SoH) e a vida útil remanescente (RUL), com redes neurais, redes recorrentes (LSTM/GRU) e outros modelos de aprendizado de máquina. São discutidos a preparação de dados de ciclagem, a seleção de variáveis, o treinamento, a validação e a avaliação dos modelos.

  Na segunda parte, o minicurso trata do balanceamento de células: por que os desequilíbrios surgem, as diferenças entre estratégias passivas e ativas e como a IA pode tornar o balanceamento mais adaptativo, aumentando a capacidade útil do pack e reduzindo a degradação.

  AI-Driven Battery Monitoring: How Artificial Intelligence Is Reshaping State Estimation, Health Prognostics and Reliability in Energy Storage Systems

  Prof. Remus Teodorescu · Aalborg University, DinamarcaDenmark

  Resumo (em inglês)Abstract

  Prof. Remus Teodorescu discusses how Artificial Intelligence is transforming the way batteries are monitored, managed and maintained in modern energy storage systems. Conventional battery management systems rely mainly on physics-based models and limited onboard measurements, which often struggle to capture non-linear behaviour, temperature effects and long-term degradation.

  The talk explores how data-driven and hybrid approaches can improve SoC and SoH estimation, Remaining Useful Life prediction and early fault detection. It also addresses cloud-connected and digital twin architectures, in which operational data continuously update battery models and support predictive maintenance.

  Finally, Prof. Teodorescu shares perspectives on the next generation of intelligent battery systems and on challenges such as data availability, model generalisation and real-time implementation.

  Microgrids and the Role of Energy Storage: Challenges and Opportunities for Reliable, Flexible and Sustainable Power Systems

  Prof. João Marcus Soares Callegari

  Resumo (em inglês)Abstract

  Prof. João Marcus Soares Callegari discusses microgrids and the central role of battery energy storage in their reliable and efficient operation, both connected to the main grid and in islanded mode.

  The talk covers microgrid architectures, operating modes and control hierarchies, and how storage contributes to power balancing, frequency and voltage support, renewable smoothing and seamless transitions between operating modes. It then addresses the main challenges: sizing and integration of battery systems, grid-forming and grid-following converter control, energy management, the impact of operation on battery lifetime, protection and economic viability.

  A Web-Based Battery Management System (BMS) Software Developed at GESEP: Characteristic Curves, Charging and Discharging Methods, and Cell Balancing Strategies

  Paulo Henrique Souza Ferreira · GESEP

  Resumo (em inglês)Abstract

  Paulo Henrique Souza Ferreira presents the BMS software developed at GESEP, which runs entirely on a web platform and makes the analysis of battery behaviour more accessible and interactive, with no local installation.

  The talk covers the tool's three main features: battery characteristic curves, charging and discharging methods such as CC and CC-CV, and cell balancing strategies. It also discusses the software architecture, its use in teaching and research, and planned improvements.
