Harahap, Rosihan Arby (2018) Identifikasi Rentang Waktu Pengisian Terhadap State Of Health Baterai Valve-Regulated Lead Acid (VRLA). Sarjana thesis, Universitas Brawijaya.
Abstract
State of Health baterai adalah suatu ukuran kemampuan sebuah baterai untuk menyimpan dan menyalurkan energi listrik. Nilai Estimasi State of Health pada sebuah baterai adalah suatu parameter penting dalam pemakaian baterai karena layak atau tidaknya baterai untuk tetap digunakan mengacu pada nilai estimasi tersebut. Berhubungan dengan semakin majunya perkembangan baterai Lead Acid hingga bertambahnya penggunaan baterai Valve-Regulated Lead Acid (VRLA) dalam sistem kelistrikan, maka pada penelitian ini akan dibahas keterkaitan antara State of Health baterai dengan rentang waktu pengisian, rancang bangun sebuah alat yang mampu menghitung nilai State of Health sebuah baterai VRLA dan menyimpan parameter tegangan, arus dan waktu selama proses pengisian. Data tersebut diolah di personal computer serta diidentifikasi keterkaitan antara rentang waktu pengisian dengan nilai State of Health suatu baterai. Metode yang dijadikan referensi nilai State of Health adalah metode perbandingan antara kapasitas akhir pengisian dan kapasitas nominal baterai tersebut. Hasil dari penelitian ini menunjukkan alat ini mampu membaca arus perubahan hingga 5 A dengan error pembacaan 2,828% serta sensor tegangan yang mampu membaca tegangan hingga 25 V dengan error pembacaan sebesar 0,257%. Hasil identifikasi menunjukkan metode perbandingan waktu pengisian baterai bekas terhadap baterai baru memiliki rentang error mulai dari 1,593% hingga 39,941% dengan persamaan trendline y = -0,5874x + 48,167 ( x = SOH). Batas error maksimal State of Health Baterai yang dapat diterima harus memiliki nilai dibawah 6% seperti yang ditunjukkan oleh Baterai Bekas 1 dan 2. Sedangkan untuk Baterai Bekas 3 dan 4 memiliki error melebihi 6% karena baterai yang memiliki nilai State of Health jauh di bawah 80% sudah dinyatakan sebagai baterai tidak layak pakai.
English Abstract
The battery state of health (SOH) is a measure of the battery’s ability to store and deliver electrical energy. The Value of the SOH on a battery is an important parameter because the feasible of the battery is based on this estimated value. Due to the increasing development of Lead-acid batteries to the increasing usage of Valve-Regulated Lead Acid (VRLA) batteries in electrical systems, this study will discuss the relationship between SOH of the battery with the charging time interval, design of a tool that can calculate the value State of Health a VRLA battery also store voltage, current and time parameters during charging process. The data is processed in personal computer and then identified the relationship between the charging time interval with the value of the SOH of a battery. The method which is used as a reference value State of Health is Coulomb Counting method which is comparison between the final charging capacity and the nominal capacity of the battery. The results of this study show that this tool is able to read the current changes up to 5A with error reading of 2,828% and voltage sensors capable of reading voltages up to 25 V with error readings of 0,257%. The results of this identification shows that the method of comparison of charging time has an error ranging from 1,593% to 39,941% with trendline’s equation y = -0,5874x + 48,167 ( x = SOH). The maximum error limits of SOH Battery that can be used should be 6% as provided by the 1st and 2nd Batteries. As the Used Battery 3 and 4 have errors exceeding 6% because batteries that have values below 80% have been replaced as the battery is not feasible to used.
