“…These results indicate that the treatment of SOC 25% discharging current of 0.8 A in the cycle range 1-5 the battery capacity is not full. The results of 10 cycles of SOC 100%, 50%, and 25% were analyzed by calculating the voltage efficiency, capacity efficiency, and energy efficiency as in the previous study 27 Figure 12. Capacity efficiency has a value proportional to the greater SOC value.…”

Three-cells dynamic lead-acid battery has been widely manufactured as the latest secondary battery technology. It is being carried out by 10 cycles of charge-discharge treatment with a various types of SoC, such as 100% (Full charge 5100 mAh), 50% (2550 mAh), 25% (1275 mAh) and discharge current of 0.8A. This experiment aims to analyze the treatment of SOC conditions on the performance of the lead-acid battery. The cyclicality test has performed using a Battery Management System (BMS) by applying an electric current at charging 1 A and discharging 0.8A. The results of the SOC charging conditions at 100%, 50%, 25% respectively gave a difference in the value of voltage efficiency of 84%, 87%, 88%, capacity efficiency values of 84%, 80%, 69%, energy efficiency values of 70%, 70%, 62%. The 100% and 50% SOC treatments showed better performance and battery energy the 25% SOC treatment. This research can be a recommendation to predict the performance of the lead-acid battery model during the charging and discharging process.

“…Pada siklus ke-1 kapasitas charge-discharge yang dihasilkan sebanding dengan efisiensinya mencapai 107,67% , namun pada siklus ke-2 dan ke-3 nilai kapasitas discharge tidak sebanding dengan kapasitas charge yang dihasilkan pada baterai. Hal ini mengindikasikan bahwa proses discharge pada siklus ke-2 dan ke-3 tidak mampu melucuti semua elektron dari reaksi redoks yang terjadi di anoda [35] . Oleh karena itu, nilai efisiensi yang dihasilkan cenderung menurun drastis.…”

The limited source of Lithium (Li) as the main material for battery cathodes has become a problem in the development of the new and renewable energy (EBT) sector. Based on their reduction potential and availability on earth, elements that might be suspected include Potassium (K), Sodium (Na), Magnesium (Mg) and Calcium (Ca). All cannot be obtained from natural ingredients, one of which is blondo. Blondo is a by-product of coconut oil processing that has not been used optimally. This study used the calcination process by varying the time (5, 7, 9 hours) and temperature (450, 550, 650°C) to obtain optimal oxide compounds from blondo. Making the cathode using a mixture of blondo and Polvinyl Alcohol (PVA) with a composition ratio of 20:1 attached to a stainless steel plate. Testing the percentage of oxide compounds was carried out using X-Ray Fluorescence (XRF) which showed that the calcination process caused the percentage levels of oxide compounds to increase K2O, P2O5, MgO and Cl. However, when the calcination time and temperature were increased, it did not give a much different effect on the levels of oxide compounds produced previously. The effect of calcination temperature is known from the results of X-Ray Diffraction (XRD) which shows that the higher the calcination temperature, the smaller the crystal size of the oxide compound. At temperatures of 450, 550 and 650°C the yields are 50.0; 47.5 and 36.4 nm. This is also supported by the results of XRF testing where K2O is the most dominant component of the oxide compound in calcined blondo. The test as a cathode material was carried out for three cycles resulting in an average charge capacity of 14.67 mAh, and an average discharge capacity of 5.34 mAh so that the average efficiency was 55.68%.

“…Seperti siklus pertama, tegangan juga mulai turun drastis saat menyentuh angka 1,5 V. Hal ini menunjukkan pada sel aki ini memiliki nilai Vcutoff sebesar 1,5 V. Pada penelitian yang dilakukan oleh Khairati et al (2018) dan Ghufron et al (2017), Vcutoff bernilai 1,8 V per selnya. Sedangkan, untuk aki 6 V memiliki nilai Vcutoff sebesar 5,50 V seperti yang dilaporkan oleh Pranata et al (2019). Selain itu, pada penelitian Segara et al (2013) memiliki nilai Vcutoff sebesar 10,5 V untuk aki 12 V. Tegangan akhir sel aki setelah tidak diberi beban menunjukkan angka 1,473 V. Setelah itu, dilanjutkan dengan proses charging kembali, hingga mencapai nilai konstan pada tegangan 2,240 V.…”

AbstrakEnergi listrik masih menjadi energi paling dibutuhkan pada saat ini. Tetapi, jumlah kebutuhan energi tidak sesuai dengan ketersediaan sumber energi. Maka dari itu, energi listrik perlu disimpan. Baterai merupakan perangkat elektronik yang dapat menyimpan energi listrik. Pada penelitian ini digunakan jenis baterai sekunder, yaitu akumulator (aki). Aki yang digunakan yaitu aki bekas yang memiliki konstruksi yang masih bagus dan memiliki tegangan per sel aki sebesar 2 V. Tujuan dari penelitian ini, yaitu (1) menganalisis performa elektroda Pb-PbO2 saat proses charge dan discharge muatan pada sel aki, dan (2) mengukur kapasitas listrik sel aki yang digunakan. Sel aki yang diuji berasal dari aki bekas dengan merk Yuasa tipe YT7C dengan spesifikasi 12 V 6 Ah. Proses pengukuran charge dengan memberikan tegangan 6 V pada sel aki, dan proses discharge dengan memberikan beban lampu 2,5 V 0,3 A. Berdasarkan data hasil pengukuran, elektroda Pb-PbO2 masih menunjukkan kinerja yang baik dalam proses pengisian dan pengosongan muatan. Hal ini ditunjukkan dengan nilai tegangan per sel aki masih berada di kisaran nilai 2 V, walaupun telah diuji selama 2 siklus. Selain itu, nilai kapasitas sel aki yang terukur sebesar 0,9 Ah. Nilai tersebut sudah mendekati nilai standar spesifikasi dari aki tersebut, yaitu sebesar 1 Ah.Kata Kunci: sel aki, charge-discharge, kapasitas aki AbstractElectrical energy is still the energy most needed today. However, the amount of energy needs does not match the availability of energy sources. Therefore, the energy needs to be stored. A battery is an electronic device that can store electricity. In this study, the type of secondary battery used is as an accumulator. The accumulator used is a former accumulator that still has a good construction and a voltage per cell of 2 V. The purpose of this study, is (1) analyzing the performance of Pb-PbO2 electrodes during the charge and discharge process of the accumulator cell, and (2) measuring the capacity of the accumulator. The accumulator cells tested were from a former accumulator Yuasa brand YT7C type with 12 V 6 Ah specification. The charge process provides a 6 V voltage to the battery cell, and the discharge process provides a 2.5 V 0.3 A lamp load. Based on the test data, the Pb-PbO2 electrode still shows good performance in the charge and discharge process. It is indicated by the voltage value per cell which is still in the range of 2 V, even though it has been tested for 2 cycles. Besides, the measured accumulator cell capacity value is 0.9 Ah. This value is close to the accumulator standard specification value, which is equal to 1 Ah.Keywords: accumulator cell, charge-discharge, accumulator capacity
