13 Hücreli Batarya Paketi için Flyback Dönüştürücü Tabanlı Aktif Hücre Dengeleme: Tasarım ve MATLAB/Simulink Uygulaması

Öz

Elektrik enerjisi, modern yaşamın sürdürülebilirliği ve teknolojik gelişimi açısından temel bir gereksinimdir. Elektrikle çalışan sistemlerin şebekeden bağımsız ortamlarda kullanılabilmesi, enerjinin depolanmasını zorunlu kılmakta; bu gereksinim doğrultusunda pil ve batarya teknolojileri geliştirilmiştir. Batarya teknolojilerindeki performans artışı ve maliyetlerin azalması, otomotiv sektörü başta olmak üzere pil teknolojisinin uygulama alanlarını oldukça genişletmiştir. Büyük ölçekli batarya paketlerinin güvenli, verimli ve uzun ömürlü bir şekilde işletilebilmesi için Batarya Yönetim Sistemleri (BYS) kritik bir rol oynamaktadır. BYS’nin temel bileşenlerinden biri olan hücre dengeleme sistemleri, seri bağlı hücreler arasındaki gerilim ve şarj dengesizliklerini gidererek sistem performansını ve batarya ömrünü artırmaktadır. Bu çalışmada, 13 hücreden oluşan bir batarya paketi için aktif hücre dengeleme modeli MATLAB/Simulink ortamında tasarlanmış ve sistemin performansı başarıyla analiz edilmiştir. Elde edilen sonuçlar grafiksel verilerle desteklenerek değerlendirilmiştir.

Flyback Converter-Based Active Cell Balancing for a 13-Cell Battery Pack: Design and MATLAB/Simulink Implementation

Öz

Electrical energy is a fundamental requirement for the sustainability and technological development of modern life. The ability to use electrically powered systems in off-grid environments necessitates energy storage; to meet this need, battery and accumulator technologies have been developed. Increased performance and reduced costs in battery technologies have significantly expanded their application areas, particularly in the automotive sector. Battery Management Systems (BMS) play a critical role in ensuring the safe, efficient, and long-lasting operation of large-scale battery packs. Cell balancing systems, a fundamental component of BMS, improve system performance and battery life by correcting voltage and charge imbalances between series-connected cells. In this study, an active cell balancing model for a 13-cell battery pack was designed in the MATLAB/Simulink environment, and the system's performance was successfully analyzed. The obtained results were evaluated with the support of graphical data.
