Abstract

Baterai jenis lithium-ion kini dipilih sebagai penyimpan energi pada kendaraan lsitrik dikarenakan power density dan energy density yang lebih besar dibandingkan baterai jenis lain. Namun, baterai lithium ion memiliki kekurangan yakni sangat sensitif terhadap overcharge. Selain itu, masalah ketidakseimbangan kapasitas baterai tersusun seri dapat mempengaruhi performa baterai secara keseluruhan. Dalam tugas akhir ini diimplementasikan skala laboratorium sistem pemantauan dan proteksi pada empat sel baterai lithium-ion tersusun seri agar baterai lebih aman dari overvoltage, undervoltage dan overheat . Selain itu ekualisasi untuk menyeimbangkan kapasistas baterai sehingga masa hidup dan kapasitas baterai dapat diperpanjang.. Hasil pengujian skala laboratorium menunjukan pemantauan tegangan mendapat error terbesar 1,25% dan pemantauan suhu mencapai error terbesar 4,9%. Sistem proteksi baterai dapat bekerja memutus koneksi baterai sehingga menjadi sirkuit terbuka jika mendeteksi overvoltage, undervoltage, dan overheat. Serta ekualisasi 4 baterai lithium tersusun seri dapat dialkukan dengan waktu tempuh 48 menit. ======================================================================================================================== Lithium-Ion batteries are now chosen as the energy storage in electric vehicles because the power density and energy density that are greater than other batteries. However, lithium ion batteries have a deficiency that is very sensitive to overcharge. In addition, the battery capacity imbalance composed of series may affect overall battery performance. In this final project will be implemented in laboratory scale, monitoring and protection systems in four cell lithium-ion batteries composed of series to be more secure from overvoltage, undervoltage, and overheat. Additionally equalizaiton to balance the battery capacity so that the life span and the battery capacity can be extended. The test results show from laboratory scale. Voltage monitoring got the biggest error around 1,25% and tempereature monitoring got the biggest error around 4,9%. Battery protection systems can work and disconnect the battery so that becomes an open circuit if detects overvoltage, undervoltage, and overheat. As well as equalization of 4 series lithium battery can be completed and takes about 48 minutes.
