Abstract
Heat generation inside of the battery cell is one of the most important factors affecting the life time of batteries. Due to increasing of daily use of batteries, the thermal analysis methods of the batteries get importance by the researchers. In this study, the heat generation inside of the pouch battery cell is investigated. In order to validate the numerical results, the experiments are performed for 1C and 2.5C discharge rates of 3.7V, 2.1Ah battery cell. The electrical equivalent circuit thermal model is taken into account in order to simulate the heat generation inside of the battery cell. The comparison of the numerical results with the experimental data showed that there is a good consistency with numerical and experimental results. Validation of the model with the experimental data is in the 4% error band. The model can be used for other discharge rates

Abstract
Batarya hücresi içerisindeki ısı üretimi bataryaların
ömürlerini açısından en önemli faktörlerden biri
olmaktadır.Bataryaların günlük hayatta kullanımının artması
nedeni ile, bataryaların ısıl analiz metotları araştırmacılar
tarafından önem kazanmaktadır. Bu çalışmada, zarf tipi batarya
hücresi içerisindeki ısı üretimi incelenmiştir. Sayısal sonuçları
doğrulamak için 3.7 V, 2.1Ah batarya hücresine 1C ve 2.5C deşarj
oranlarında deney yapılmıştır. Elektriksel eşit devre ısıl modeli
batarya hücresindeki ısı üretimini modellemek için ele alınmıştır.
Sayısal sonuçların deneysel veriler ile karşılaştırılması sayısal ve
deneysel sonuçlarda iyi bir uyum olduğunu göstermiştir. Model ile
deneysel sonuçlar %4 hata payı içerisinde doğrulanmıştır. Buna
göre hazırlanan model diğer deşarj oranlarında da
kullanılabilecektir.
