Abstract

Superconductors are materials that can conduct electric current without resistance. The application of superconducting materials in the field of transportation is the super-fast train or Magnetic Levitation (MagLev). BPSCCO added with Al2O3 nanoparticles has been successfully synthesized using the wet mixing method. In this study, variations in the sintering temperature (840 and 880oC) were carried out using the wet mixing method. The performance of BPSCCO with the addition of Al2O3 was carried out by testing XRD, SEM, and I-V. Based on the results of XRD characterization, the volume fraction, impurity, and crystal size respectively were 57.49% (BPSCCO-840), 38.96% (BPSCCO-880); 42.5% (BPSCCO-840), 38.96% (BPSCCO-880) and 21.38 nm (BPSCCO-840); 28.84 nm (BPSCCO-880). Based on the results of the SEM test, the sample slabs are regular and have little free space. Based on the I-V test results, the BPSCCO-840 sample has the highest electrical conductivity of 2.4x104 S/m at a current of 0.6 mA and the BPSCCO-880 sample has a conductivity of 2.8x104 S/m at a current of 0.3 mA

Abstract

Penyimpanan energi merupakan komponen terpenting dalam sistem penggerak kendaraan listrik atau electric vehicles (EV). Hybrid storage system yang menggunakan baterai dan superkapasitor banyak digunakan karena dapat menghasilkan sistem penyimpanan energi listrik yang baik dengan kapasitas penyimpanan besar, kepadatan daya dan kepadatan energi tinggi, siklus charge-discharge cepat, dan cycle life panjang. Namun, pengaplikasian hybrid storage system pada kendaraan listrik memerlukan banyak komponen pendukung dan parameter kompleks yang digunakan untuk menciptakan sistem penyimpanan energi pada kendaraan listrik yang efektif. Sistem simulator diperlukan untuk memudahkan analisis dan investigasi kinerja perangkat penyimpanan energi pada teknologi kendaraan listrik. Pada penelitian ini, dilakukan inovasi pembuatan simulator dan alat uji coba performa gabungan baterai LiFePO4 dan superkapasitor berbasis kontroler dan motor BLDC, dengan memperhatikan pengaruh gaya gesek dan laju kecepatan yang menyerupai kondisi sebenarnya. Hasil uji coba menunjukkan bahwa motor BLDC bekerja lebih efisien pada revolutions per minute (rpm) tinggi, dimana daya yang dibutuhkan tidak lagi meningkat secara signifikan meskipun rpm bertambah. Penelitian diharapkan memberikan kontribusi terhadap pengembangan infrastruktur pendidikan dan penelitian di bidang kendaraan listrik di Indonesia.
