Abstract

The development of electric vehicle (EV) technology is advancing rapidly in various aspects, driven by the need for environmentally friendly and efficient transportation solutions. Electric vehicles are powered by electric motors, which require an energy source in the form of a battery arranged into a battery pack. A battery pack consists of battery cells arranged in series and parallel to meet the energy specifications required by the electric vehicle. Currently, lithium batteries are considered the best choice for electric vehicles due to their advantages in energy density and cost per cycle compared to other types of batteries. In the design of this battery pack, the vehicle's specifications require a voltage of 144V to power the electric motor, with a target usage time of 5 hours, leading to a designed capacity of 220Ah. The battery used is a Lithium Ferro Phosphate (LFP) type with specifications of 3.2V and 22Ah. Based on mathematical calculations, the battery pack design utilizes 10 batteries in parallel and 48 in series to achieve the required specifications. The design also takes into account the maximum storage space inside the vehicle, with the battery pack divided into two banks placed in the front and rear of the vehicle to maintain a balanced center of gravity. After assembly, voltage measurements showed that the maximum voltage achieved was 153.6V. Testing was conducted after the batteries were installed in the vehicle, which showed that the vehicle could be operated for 19 hours with an average current of 11.5A. From the test results, the battery capacity was calculated to be approximately 218.5Ah. The test results indicate that the battery performance does not fully match the theoretical calculations, due to factors such as battery characteristics and energy losses in the vehicle system.

Abstract

5G Core (5GC) Network merupakan salah satu teknologi utama pada teknologi seluler generasi ke-5. Perubahan besar yang terjadi pada 5GC adalah perubahan dari arsitektur monolithic menjadi arsitektur yang modular dan aksesnya dibuka untuk umum. Hal ini merubah pengembangan 5GC menjadi lebih baik. Beberapa penelitian yang sudah dilakukan masih menggunakan 5GC non-standalone yang ditandai dengan hadirnya Evolved Packet Core (EPC) dalam implementasinya. Maka dari itu penelitian ini bertujuan untuk mengimplementasikan arsitektur 5GC standalone yang didefinisikan oleh 3GPP release 15 pada baremetal server. Kemudian 5GC diintegrasikan dengan User Equipment (UE) dan Radio Access Network (RAN). Percobaan ini menggunakan metode penelitian yang mencakup instalasi dan konfigurasi source code Free5GC, integrasi dengan simulator UERANSIM, serta pengujian performa menggunakan metrik bandwidth, throughput, dan round-trip time (RTT). Setelah dilakukan pengukuran performa menggunakan beberapa metrik pengukuran dari 5GC yang telah dibangun dapat disimpulkan bahwa 5GC yang dibangun berhasil diimplementasikan dan berfungsi dengan baik dalam mendukung konektivitas data. Pengujian performa mencatat bandwidth rata-rata sebesar 3,5 Gbps, throughput rata-rata 21,04 Mbps untuk unduh dan 19,125 Mbps untuk unggah, serta RTT rata-rata 21,229 ms. Penelitian ini memberikan kontribusi penting dalam pengembangan jaringan 5G yang terbuka dan dapat diandalkan, terutama pada aspek konektivitas data. 5G Core (5GC) Network is a key technology in fifth-generation cellular systems. One of the significant advancements in 5GC is the shift from a monolithic to a modular architecture with open access, enabling better development of the technology. However, many existing studies still focus on non-standalone 5GC, which includes the Evolved Packet Core (EPC) in its implementation. This study aims to implement a standalone 5GC architecture, as defined by 3GPP Release 15, on a bare metal server. The implementation integrates 5GC with User Equipment (UE) and Radio Access Network (RAN). The research methodology involves installing and configuring the Free5GC source code, integrating it with the UERANSIM simulator, and evaluating its performance using metrics such as bandwidth, throughput, and round-trip time (RTT). Results show that the implemented 5GC operates successfully and effectively supports data connectivity. The performance tests recorded an average bandwidth of 3.5 Gbps, a download throughput of 21.04 Mbps, an upload throughput of 19.125 Mbps, and an average RTT of 21.229 ms. This study contributes significantly to the advancement of open, flexible, and reliable 5G networks, particularly in enhancing data connectivity performance.
