Abstract

PT. GS Battery memproduksi baterai CF (Container Formation) atau unformed plate yang tidak dapat diuji menggunakan APM-4HL seperti pada baterai Non-CF (Non-Container Formation) atau formed plate karena tegangan terlalu rendah sehingga dikembangkan sistem polarity tester berbasis kapasitansi menggunakan LCR Meter Hioki IM3533. Namun, sistem ini pada awalnya mengalami ketidakstabilan pembacaan sehingga tidak dapat mendeteksi sel terbalik. Penelitian ini bertujuan meningkatkan kestabilan dan akurasi sistem dengan metode kapasitor plat sejajar sebagai pembanding antara pembacaan nilai kapasitansi dari LCR Meter Hioki IM3533 dengan perhitungan rumus kapasitor plat sejajar berdasarkan dimensi plat yang telah diukur. Kemudian setelah dilakukan modifikasi wiring panel polarity tester yaitu serabut coaxial tidak disambungkan ke ground dan penambahan ground rangka mesin untuk mengurangi noise maka didapatkan peningkatan kestabilan pada masing-masing sequence seperti pada sequence 1 terjadi peningkatan kestabilan 76%, pada sequence 2 terjadi peningkatan kestabilan 86%, pada sequence 3 terjadi peningkatan kestabilan 66%, sequence 4 terjadi peningkatan kestabilan 94%, dan sequence 5 terjadi peningkatan kestabilan 58%. Selain itu, setelah dilakukan pengujian ketahanan sistem didapatkan bahwa sistem ini 100% dapat mendeteksi sel terbalik pada baterai sehingga dapat mengurangi baterai reject dari sel terbalik serta dapat bekerja secara optimal 100% selama 2 minggu dan membutuhkan perawatan berupa pembersihan jarum agar performa sistem tidak menurun 20%. Kemudian Cycle time proses polarity tester menjadi lebih optimal dari 12 detik menjadi 6,5 detik atau menurun sebesar 45,83% sehingga waktu pengecekan sel terbalik menjadi lebih efisien pada tahap assembly baterai VRLA. Selanjutnya, frekuensi juga berpengaruh pada konstanta dielektrik (k) seperti pada frekuensi 200kHz sequence 1 konstanta dielektriknya sebesar 3,02 sedangkan pada frekuensi 50kHz sebesar 3,22 dan pada frekuensi 10kHz sebesar 3,30. Hal tersebut dikarenakan pada frekeuensi tinggi molekul dalam bahan mengalami keterbatasan waktu untuk menyesuaikan orientasi mereka dengan cepat terhadap perubahan medan listrik yang semakin cepat.Kata kunci: Kapasitor plat sejajar, LCR Meter Hioki IM3533, Polarity tester, Sel baterai terbalik

PT. GS Battery manufactures CF (Container Formation) batteries or unformed plates, which cannot be tested using the APM-4HL as with Non-CF (Non-Container Formation) or formed plate batteries due to their very low voltage. Therefore, a capacitance-based polarity tester system was developed using the Hioki IM3533 LCR Meter. However, this system initially experienced unstable readings, making it unable to detect reversed cells. This study aims to improve the stability and accuracy of the system by utilizing the parallel-plate capacitor method as a reference to compare the capacitance readings from the Hioki IM3533 LCR Meter with theoretical calculations based on the measured plate dimensions. Following a modification of the polarity tester panel wiring—namely by disconnecting the coaxial shield from the ground and adding a machine frame ground to reduce noise—stability improvements were achieved in each sequence: sequence 1 increased by 76%, sequence 2 by 86%, sequence 3 by 66%, sequence 4 by 94%, and sequence 5 by 58%. In addition, after conducting a system endurance test, it was found that the system could detect reversed cells in batteries with 100% accuracy, thereby reducing battery rejection due to reversed cells and maintaining optimal performance for two weeks, requiring only needle cleaning maintenance to prevent a 20% performance drop. The polarity tester’s cycle time also became more efficient, decreasing from 12 seconds to 6.5 seconds, or by 45.83%, thus improving the efficiency of reversed cell detection during the VRLA battery assembly process. Furthermore, frequency was found to affect the dielectric constant (k): at 200 kHz in sequence 1, the dielectric constant was 3.02, while at 50 kHz it was 3.22, and at 10 kHz it reached 3.30. This occurs because, at higher frequencies, the molecules in the material have limited time to reorient in response to the rapidly changing electric field.
