Abstract
PT. Panggung Electric Citrabuana berencana meningkatkan efisiensi operasional dengan menerapkan Automated Guided Vehicle (AGV) pada proses distribusi produk di anak perusahaannya, PT. Akari Indonesia. Salah satu komponen penting dari AGV adalah sistem dayanya, yang biasanya menggunakan baterai Valve Regulated Lead Acid (VRLA) karena keandalan dan biaya yang relatif murah. Namun, pengisian baterai VRLA memerlukan pengendalian yang cermat untuk pengisian yang cepat dan untuk mencegah overcharging atau undercharging yang dapat merusak baterai dan mengurangi efisiensinya. Terdapat beberapa metode pengisian baterai VRLA, termasuk Constant Current (CC), Constant Voltage (CV), dan Constant Current Constant Voltage (CC-CV). Metode CC-CV, yang menggabungkan keunggulan metode CC dan CV, diakui sebagai metode yang paling efisien dan aman. Dalam implementasinya, konverter buck digunakan untuk mengatur tegangan dan arus pengisian, sementara sistem kontrol PID (Proportional-Integral-Derivative) diterapkan untuk memastikan pengaturan yang presisi dan stabil. Penentuan parameter PID dilakukan dengan metode Ziegler Nichols 2 yaitu osilasi dan pengaturan parameter PID sesuai karakteristik masing-masing pengontrol. Berdasarkan hasil pengujian yang dilakukan, Metode CC-CV memiliki reliabilitas tinggi dalam menjaga tegangan dan arus pengisian secara konstan dan dapat menghasilkan arus konstan 1 Ampere dan tegangan konstan 13,8 Volt. Arus mulai menurun setelah data ke 1200 atau setelah 52 menit karena tegangan baterai telah melebihi nilai batas yang telah ditentukan. Sehingga pengisian akan mulai berganti ke mode CV. Pada mode CV tegangan pengisian akan terus dijaga konstan sebesar 13.8 volt hingga arus pengisian mendekati nol atau nilai 0.1 ampere. Tegangan keluaran konverter buck stabil pada nilai 13.8 volt saat proses pengisian baterai dengan respon optimal rise time = 0.0002s, settling time = 0.00015s dan overshoot = 0 volt menggunakan metode pengaturan parameter PID sesuai karakteristik masing-masing pengontrol sebagai penyempurna metode Ziegler Nichols 2 dengan nilai Kp = 0.02, Ki = 20 dan Kd = 0.00016.
=================================================================================================================================
PT. Panggung Electric Citrabuana plans to improve operational efficiency by implementing Automated Guided Vehicle (AGV) in the product distribution process at its subsidiary, PT. Akari Indonesia. One of the important components of AGV is its power system, which usually uses Valve Regulated Lead Acid (VRLA) batteries due to their reliability and relatively low cost. However, charging VRLA batteries requires careful control for fast charging and to prevent overcharging or undercharging that can damage the battery and reduce its efficiency. There are several methods of charging VRLA batteries, including Constant Current (CC), Constant Voltage (CV), and Constant Current Constant Voltage (CC-CV). The CC-CV method, which combines the advantages of the CC and CV methods, is recognized as the most efficient and safe method. In its implementation, a buck converter is used to regulate the charging voltage and current, while a PID (Proportional-Integral-Derivative) control system is applied to ensure precise and stable settings. Determination of PID parameters is carried out using the Ziegler Nichols 2 method, namely oscillation and PID parameter settings according to the characteristics of each controller. Based on the test results, the CC-CV method has high reliability in maintaining constant charging voltage and current and can produce a constant current of 1 Ampere and a constant voltage of 13.8 Volts. The current begins to decrease after the 1200th data or after 52 minutes because the battery voltage has exceeded the specified limit value. So that charging will start to switch to CV mode. In CV mode, the charging voltage will continue to be kept constant at 13.8 volts until the charging current approaches zero or a value of 0.1 ampere. The output voltage of the buck converter is stable at 13.8 volts during the battery charging process with an optimal response of rise time = 0.0002s, settling time = 0.00015s and overshoot = 0 volts using the PID parameter setting method according to the characteristics of each controller as a refinement of the Ziegler Nichols 2 method with a value of Kp = 0.02, Ki = 20 and Kd = 0.00016.
