Abstract
Lithium iron phosphate (LiFePO4) batteries offer advantages in generating high energy and capacity. Their good thermal stability and resistance to heat make them safer compared to some other types of lithium batteries, as they pose a lower risk of fire and explosion. Additionally, these batteries can operate within a wide temperature range, typically from -20°C to 60°C, enabling their use in various environmental conditions. LiFePO4 batteries also support high discharge rates, meaning they can deliver large amounts of power in a short period, which is very useful for applications requiring instant power surges. A well-managed LiFePO4 battery with a good Battery Management System (BMS) will provide optimal performance in electric vehicles, renewable energy storage systems, medical equipment, and other applications requiring high durability and reliability. The monitoring system functions effectively, showing an average testing error of 0.037% for voltage sensors, 0.53% for temperature sensors, and 1.89% for current sensors. Charging tests using the constant current and constant voltage method with a current of 3.6A and a voltage of 12V yielded satisfactory results, with an average voltage increase per cell of 0.56V within 120 minutes. Discharge testing using a 12V 1.8A DC Motor load also proceeded well, with an average voltage drop of 0.27V.

| Uncontrolled Keywords: | Baterai lithium iron phosphate (LiFePO4) memiliki keunggulan dalam menghasilkan energi dan kapasitas yang tinggi. Stabilitas termal yang baik dan ketahanan terhadap panas membuatnya lebih aman dibandingkan dengan beberapa jenis baterai lithium lainnya, karena risiko kebakaran dan ledakan yang lebih rendah. Selain itu, baterai ini dapat beroperasi dalam rentang suhu yang luas, biasanya dari -20° C hingga 60° C, sehingga memungkinkan penggunaan dalam berbagai kondisi lingkungan. Baterai ini juga mendukung discharge rate yang tinggi, yang berarti dapat memberikan daya besar dalam waktu singkat, sangat berguna untuk aplikasi yang membutuhkan lonjakan daya instan. Baterai LiFePO4 dengan BMS (Battery Management System) yang baik memberikan kinerja optimal dalam kendaraan listrik, sistem penyimpanan energi terbarukan, peralatan medis, dan aplikasi lainnya yang memerlukan daya tahan dan keandalan tinggi. Sistem monitoring berfungsi dengan baik, menunjukkan rata-rata kesalahan pengujian sebesar 0,037% pada sensor tegangan, 0,53% pada sensor suhu, dan 1,89% pada sensor arus. Pengujian pengisian daya dengan metode arus konstan dan tegangan konstan (constant current dan constant voltage) menggunakan arus 3,6A dan tegangan 12V menunjukkan hasil yang memuaskan, dengan rata-rata kenaikan tegangan per sel sebesar 0,56V dalam waktu 120 menit. Pengujian pengosongan daya dengan beban Motor DC 12V 1,8A juga berjalan dengan baik, dengan penurunan tegangan rata-rata sebesar 0,27V. | |||||||||
