“…Through the use of resistor components, the passive equalizing procedures remove the excess charge from fully energised cells, making all the cells with a charge that is identical to that of the lowest cell [60]. Passive balancing is suitable for lower power applications such as electrical vehicles [12].…”

The battery pack performance and expected lifespan are crucial in electric vehicle applications. Balancing the charge on a battery pack connected in series and parallel is crucial due to manufacturing discrepancies and distinct performance of each cell in a standard battery pack. In this paper, a switched-resistor passive balancing-based method is proposed for balancing cells in a battery management system (BMS). The value of the available voltage at the battery cell terminals is balanced using resistors in an electrical circuit, and the excess voltage is eliminated. The cell balancing outcome demonstrates that the electrical circuit can maintain an even voltage across each cell. The procedure of balancing involves individually adjusting each cell’s level of charge. Passive balancing releases energy as heat by draining charge from cells that have too much charge. A passive cell balancer is a cost-effective solution and easy to install, but due to thermal loss from a resistor, it has a low energy efficiency for cell balancing and necessitates a lengthy balancing process. This passive cell balancer is an effective and reliable method for low-power devices and portable applications such as electrical vehicles. The power limits during charging and discharging are estimated using the bisection method.

“…Balancing pasif banyak diterapkan karena kesederhanaan, keandalan, dan biaya yang relatif rendah [8] [9]. Balancing pasif dilakukan dengan cara mengosongkan sel yang memiliki kapasitas lebih tinggi menggunakan resistor hingga muatan sel mendekati muatan sel terendah dalam baterai pack [10]. Proses balancing harus dilakukan seoptimal mungkin dengan waktu pengisian baterai, sehingga diperlukan teknik pengapian PWM (Pulse Width Modulation) untuk melepaskan sel-sel baterai yang tidak seimbang [10][11].…”

Baterai lithium-ion banyak digunakan pada penyimpanan energy untuk aplikasi kendaraan listrik dan kendaraan hybrid. Baterai lithium-ion memiliki power density yang besar dan juga lifetime yang panjang, sehingga dapat meningkatkan jarak tempuh dan usia kendaraan, Setelah beberapa siklus pengisian dan pengosongan terdapat salah satu cell yang berkurang performa dan kapasitasnya, sehingga menyebabkan performa dan kapasitas baterai pack berkurang sehingga tidak bisa bekerja dengan optimal. Sehingga perlu dirancang sistem cell balancing untuk meminimalkan ketidakseimbangan tegangan sel pada proses pengisian. Metode pasif cell balancing diterapkan secara luas karena kesederhanaan, keandalan, dan biaya yang relatif rendah. Proses balancing harus dilakukan secepat mungkin saat baterai sedang diisi, sehingga diperlukan teknik kontrol PWM menggunakan logika fuzzy mamdani untuk melepaskan sel baterai yang tidak seimbang. Hasilnya dibandingkan tanpa sistem balancing, sistem fixed balancing 50% duty cycle, dan sistem balancing logika fuzzy sugeno. Dari hasil simulasi dengan menggunakan fuzzy mamdani didapatkan nilai tegangan delta akhir sebesar 0,0344 volt, energi yang terisi sebesar 58,18 Wh dan State of Charge akhir sebesar 74%. Jika dibandingkan dengan metode balancing lainnya menunjukkan bahwa penggunaan metode logika fuzzy mamdani lebih optimal karena nilai tegangan delta akhir yang sangat kecil dan kapasitas baterai yang terisi lebih besar dibandingkan metode lainnya.

“…in active balancing, energy is drawn from the most charged cell and transferred to the least charged cells, usually through DC-DC converters. Since the active balancing scheme utilizes the capacitance or inductive charge shuttling to transfer charge from the cell with high charge to the cell with low charge [61], the battery balancer, or battery regulator based on active balancing topology is used to improve available capacity of a battery pack with multiple cells, and increase each cell's longevity.…”

Batteries are gaining entry into every home and office for they are widely used because of their variant benefits. However, these batteries are prone to failure caused by charge imbalance in the batteries connected in either series or parallel, which can sometimes be catastrophic and hence they require to be properly monitored in a real-time manner. There exist many battery balancing schemes which are broadly grouped into either passive or active schemes. All these schemes have their own advantages and disadvantages, and hence it is upon the user to decide on which scheme will best work for them. However, research has proven that the hybrid scheme will be the best as it couples the benefits of all schemes. This study will review the various battery cell balancing methodologies and evaluate their relationship with battery performance. At present there are a few studies tackling the mechanical vibration of battery balancing performance. This study shows that battery balancing performance during long-term should be evaluated from various temperature and vibration frequencies.INDEX TERMS Battery cell balancing, electric vehicles, hybrid schemes, and performance optimization.
