Abstract

Sistem manajemen baterai sangat diperlukan untuk mengatasi permasalahan safety system pada baterai. Themal runaway adalah salah satu masalah safety pada battery, dimana suhu battery melebihi suhu operasi yang dapat mengakibatkan panas yang keluar dari baterai akibat adanya reaksi exotermic yang berlebihan. Pada Tugas Akhir ini telah dilakukan analisis mekanisme propagasi thermal runaway yang terjadi guna mengetahui perambatan temperatur ketika kondisi charge dan discharge sampai dengan terjadinya fenomena thermal runaway sehingga dapat memberikan informasi mengenai pengaruh discharge rate (C-rate) dan state of charge (SoC) terhadap temperatur baterai dan waktu penggunaan baterai. Pada penelitian ini dilakukan simulasi dengan menggunakan software Ansys fluent untuk mengetahui mekanisme perubahan temperatur pada baterai akibat perubahan State of charge dan Discharge rate. Dari hasil penelitian didapatkan bahwa seiring kenaikan persentase SoC, nilai temperatur juga mengalami kenaikan dengan propagasi temperatur yang menyebar merata dari pusat ke seluruh permukaan dinding baterai. Nilai temperatur tertinggi terdapat pada baterai dengan variasi 3C dengan SoC 90% sebesar 323,2652 K dan waktu penggunaan paling lama ditunjukkan variasi 1C dan SoC 90% sebesar 3600 detik dan temperatur terendah mencapai 307.680 K yang ditunjukkan oleh variasi 1C dengan SoC 20% sedangkan waktu penggunaan paling cepat ditunjukkan variasi 3C SoC 20% sebesar 210 detik.

The battery management system is very necessary to overcome the problems of the battery security system. Thermal runaway is one of the safety problems in batteries, where the battery temperature exceeds the operating temperature which can result in heat coming out of the battery due to an excessive exothermic reaction. In this final project, an analysis of the thermal runaway propagation mechanism has been carried out in order to determine the temperature propagation when the charge and discharge conditions occur until the thermal runaway phenomenon occurs so that it can provide information about the discharge rate (C-rate) and state of charge (SoC) battery temperature and battery usage time. In this study, simulations were carried out using fluent Ansys software to determine the mechanism of temperature changes in the battery due to changes in the State of charge and Discharge rate. From the results of the study, it was found that as the percentage of SoC increased, the temperature also increased with temperature propagation that spread evenly from the center to the entire surface of the battery wall. The highest temperature value is found in the battery with a variation of 3C with 90% SoC of 323,2652 K and the longest usage time is indicated by a variation of 1C and 90% SoC of 3600 seconds and the lowest temperature reaches 307,680 K which is indicated by a variation of 1C with a SoC of 20% while the time the fastest usage is shown by the variation of 3C SoC 20% by 210 seconds
