Abstract
Baterai Manajemen Sistem (BMS) merupakan komponen utama pada kendaraan listrik yang bertanggung jawab dalam menjaga keamanan pengguna dan memperpanjang umur baterai. Kondisi operasional baterai yang tidak tepat seperti arus berlebih (Over Current), suhu yang terlalu tinggi (Over Temperature), arus berlebih saat dalam kondisi beban (Over Discharge), arus berlebih saat proses pengisian (Over Charge), dan hubungan pendek (Short Circuit), dapat membahayakan pengemudi. Oleh karena itu, fungsi BMS adalah untuk memperpanjang umur baterai dengan mengestimasi nilai State of Charge (SoC) dan State of Health (SoH). Dalam rangka melaksanakan fungsi tersebut, diperlukan proses akuisisi data yang akurat terkait dengan tegangan, arus, dan suhu, serta estimasi SoC dan SoH yang tepat. Sebagai solusi, dikembangkanlah sistem manajemen baterai dengan kemampuan akuisisi data yang tinggi dan kemampuan prediksi kondisi baterai yang digunakan. Untuk mencapai akurasi data yang tinggi, digunakan IC BMS tipe LTC6803 dengan tingkat kesalahan (error) maksimum yang rendah. Kemampuan akurasi ini didukung oleh sistem kontrol Arduino UNO dengan frekuensi tinggi. Selain itu, BMS yang dirancang juga dilengkapi dengan passive balancing, yang mampu menyeimbangkan nilai tegangan pada setiap sel baterai. Simulasi menggunakan Simscape Electrical digunakan untuk menunjukkan kinerja BMS, dengan menguji berbagai kondisi tegangan sel baterai dan proses pengisian. Hasil simulasi menunjukkan bahwa model BMS mampu melakukan penyeimbangan pada setiap sel baterai. Untuk memperoleh performa BMS maka dilakukan pengujian pembacaan tegangan dengan nilai selisih antara keduanya kurang dari 0,06, pengujian sensor arus dengan nilai selisih antara keduanya 0,029 dan suhu dengan nilai selisih antara keduanya 0,024, pengujian sistem penyeimbangan dan proteksi, serta pengujian pemantauan. Hasil pengujian ini menunjukan kinerja BMS yang baik

Battery Management System (BMS) is a key component in electric vehicles responsible for ensuring user safety and prolonging battery life. Improper battery operational conditions such as over current, over temperature, over-discharge during load conditions, overcharge during the charging process, and short circuits can endanger the driver. Therefore, the function of the BMS is to extend battery life by estimating the State of Charge (SoC) and State of Health (SoH). To perform this function, accurate data acquisition related to voltage, current, and temperature, as well as precise estimation of SoC and SoH, are necessary. As a solution, a battery management system with high data acquisition capabilities and predictive abilities for battery conditions is developed. To achieve high data accuracy, the BMS uses the LTC6803 IC type with low maximum error rates. This accuracy is supported by an Arduino UNO control system with high frequency. Additionally, the designed BMS is equipped with passive balancing, which can balance the voltage values of each battery cell. Simscape Electrical simulations are used to demonstrate the BMS performance by testing various battery cell voltage conditions and charging processes. The simulation results show that the BMS model can balance each battery cell effectively. To obtain BMS performance, voltage reading tests are conducted with a difference between the readings of less than 0.06, current sensor testing with a difference between readings of 0.029, and temperature testing with a difference between readings of 0.024. Testing is also done for the balancing and protection system as well as monitoring. The test results demonstrate good BMS performance.
