Abstract
Sistem pengisian arus listrik ke baterai dari sumber PV dengan teknik pengisian pulsa dilakukan untuk mendistribusikan arus listrik tinggi ke baterai tanpa menyebabkan kerusakan fungsi dan kinerja baterai melalui proses menvariasikan lebar pulsa, teknik menvariasikan lebar pulsa adalah teknik mengatur durasi waktu arus yang terdiri dari Ton, Tdisc dan Tbreak melalui pengendalian saklar elektronik, keuntungan teknik ini adalah terdapat waktu jeda (break) bagi baterai dalam proses menstabilkan elektroda selain itu tingkat kenaikan suhu baterai kecil saat proses charging berlangsung. Konsep manajemen pengisian baterai dalam sistem ini adalah proses pengisian tiga unit baterai yang berlangsung secara independent. Saat salah satu baterai berada dalam kondisi penuh, sistem akan memutuskan jalur pengisian dan dua unit baterai yang lain tetap menjaga proses pengisian tanpa terpengaruh oleh pergantian baterai. Penerapan konsep ini bertujuan untuk mempertahankan keseimbangan daya pada PV agar tetap kontinyu menyuplai energi pada titik maksimum. Implementasi konverter sepic dengan daya 80W diperoleh rata-rata hasil tracking MPP PV yang terukur sebesar 36,3W dan efisiensi konverter diperoleh >74% dengan arus rata-rata pengisian pada baterai-1, 12V/5Ah sebesar 1,83A, baterai-2 sebesar 1,7A dan baterai-3 sebesar 1,07A, sedangkan saat sistem beralih ke metode constant voltage diperoleh arus pengisian sebesar 1.10A. Perbandingan hasil simulasi antara metode MPPT dan constant voltage diperoleh tingkat rata-rata kenaikan SOC baterai pada metode MPPT sebesar 0,053% dan constant voltage sebesar 0,024% dalam durasi pengisian 6 detik pada iradian 1000W/m2 dan suhu 250C

Charging systems for battery electric current from the PV source with pulse charging technique was done to distribute high electric current to the battery without causing damage to the functionality and performance of the battery through a process to vary the pulse width, the technique of pulse widths vary was a technique to adjust the duration time of battery charging that consist Ton, Tdisc and Tbreak through the control of electronic switches. This technical advantage was there a time break for the battery in the process of stabilizing the electrode, in addition to the rate of temperature increase was small when battery charging process takes place. The concept of charge management was the process of charging three battery units independently, when one battery was in full condition, the system will break the line charge and two other units that keep the battery charging process without being influenced by the change of battery. The application of this concept aims to maintain the balance of power in order to keep a continuous supply of PV energy at the point of maximum. Implementation of the SEPIC converter with power 80W was obtained MPP PV average of 36.3W and converter efficiency obtained >74% with an average charging current to the battery-1 12V/5Ah of 1.83A, battery-2 of 1,7A and battery-3 of 1,07A, when the system switches to constant voltage method obtained charging current of 1.10A. Comparison of simulation results between constant voltage method and MPPT is gaining an average rate of increase in the battery SOC by 0.053% at MPPT method and constant voltage was 0,024% in the duration 6s on radiant1000W/m2 and temperature 250C
