Abstract

Ketidakkonsistenan pada baterai yang terhubung secara seri merupakan salah satu faktor yang mempengaruhi kinerja sekaligus lifetime baterai. Untuk memastikan sel dalam paket baterai memiliki tingkat pengisian energi yang sama, diperlukan sistem penyeimbang baterai. Namun, pemilihan metode penyeimbangan yang kurang tepat dapat memberikan respon penyeimbangan yang kurang efektif bahkan lebih krusialnya dapat menyebabkan overcharge ketika diakhir penyeimbangan baterai. Untuk mengatasi hal tersebut, penelitian ini mengusulkan pemodelan strategi pengontrolan penyeimbang aktif berbasis konverter Cuk dengan multivariabel menggunakan State of Charge (SOC) dan tegangan sebagai variabel kontrol dengan pengontrolan Fuzzy Logic Controller (FLC) yang dikombinasikan dengan Proportional Integral (PI). Hasil simulasi percobaan menunjukkan topologi penyeimbangan yang diusulkan mampu memberikan hasil penyeimbangan yang responsif mengatasi ketidakseimbangan baterai dan arus penyeimbangan yang dihasilkan adaptif menyesuaikan kondisi baterai, sehingga dapat menjaga keamanan baterai yang dibuktikan pada 10 percobaan simulasi yang sudah dilakukan salah satunya pada skenario SOC B1<B2<B3 (75%, 77%, 80%) berhasil mencapai keseimbangan 3 baterai selama 612 detik dan arus penyeimbangan diawal penyeimbaangan sebesar 0,89 A menuju titik setimbang menjadi 0,2 A.

Inconsistencies among series connected battery cells are a key factor affecting both the performance and lifetime of the battery. To ensure uniform energy levels among cells in a battery pack, an effective battery equalization system is essential. However, the use of an inappropriate equalization method may lead to suboptimal balancing responses and, more critically, the risk of overcharging near the end of the equalization process. To address this problem, This study proposes a modeling active balancing control strategy with a Cuk converter circuit based on multivariable with State of Charge (SOC) and voltage as control variables using combines a Fuzzy Logic Controller (FLC) with a Proportional-Integral (PI) controller. The simulation results show that the proposed balancing topology is capable of providing responsive balancing results to overcome battery imbalances, and the resulting balancing current adaptively adjusts to battery conditions, so that battery safety can be maintained. This is validated through ten simulation experiments, including a scenario with initial SOC values of B1<B2<B3 (75%, 77%, 80%), in which the system successfully achieved balance within 612 seconds, with the balancing current decreasing from 0.89 A at the start to 0.2 A at equilibrium.
