Abstract

Penelitian ini mengembangkan dan menyimulasikan Sistem Manajemen Energi (EMS) berbasis aturan untuk kendaraan listrik hibrida paralel (HEV) guna mengevaluasi efektivitasnya dalam mengurangi konsumsi bahan bakar dan biaya operasional. EMS, yang dirancang dengan logika ambang batas berdasarkan permintaan daya dan kondisi pengisian baterai (SOC), diuji menggunakan MATLAB/Simulink pada tiga siklus berkendara standar: UDDS, HWFET, dan FTP-75. Metrik kinerja seperti konsumsi bahan bakar, efisiensi bahan bakar, dan biaya bahan bakar dianalisis pada tiga tingkat SOC awal (0.3, 0.6, dan 0.9). Hasilnya menunjukkan bahwa EMS secara signifikan mengurangi penggunaan bahan bakar dan biaya, terutama dengan SOC awal yang lebih tinggi. Penghematan bahan bakar maksimum mencapai 91% dan penghematan biaya melebihi 66,89% dalam kondisi yang menguntungkan. Namun, penelitian ini juga mengidentifikasi keterbatasan. Dalam kondisi berkendara di jalan raya dengan SOC awal yang rendah (misalnya, HWFET 0.3), EMS mengonsumsi lebih banyak bahan bakar daripada kendaraan ICE konvensional. Analisis juga mengungkapkan seringnya perpindahan mode di dekat ambang batas SOC, yang, meskipun efektif dalam simulasi, mungkin tidak mencerminkan operasi hibrida yang realistis. Penelitian ini menyimpulkan bahwa EMS berbasis aturan menawarkan manfaat besar dalam efisiensi bahan bakar dan biaya, tetapi juga menekankan perlunya strategi yang lebih adaptif dan pemodelan baterai yang realistis dalam penelitian di masa depan.
============================================================
This study focuses on the development and simulation of a rule-based Energy Management System (EMS) for a parallel hybrid electric vehicle, aiming to evaluate its effectiveness in reducing fuel consumption and operational costs compared to a conventional internal combustion engine (ICE)-only vehicle. The EMS was designed using threshold logic based on the vehicle’s power demand and battery state of charge (SOC), then tested across three standard driving cycles: UDDS, HWFET, and FTP-75. The simulation was conducted using MATLAB/Simulink, and performance metrics such as fuel consumption, fuel economy, electric motor (EM) energy contribution, and fuel cost were analyzed at three different initial SOC levels (0.3, 0.6, and 0.9). Results showed that EMS implementation significantly reduced fuel usage and operational costs in most scenarios, particularly under higher initial SOC conditions. Maximum fuel savings reached 91%, and cost savings exceeded 66.89% in favorable conditions. However, in highway driving conditions with low initial SOC (e.g., HWFET 0.3), the EMS resulted in higher fuel usage than the conventional ICE, highlighting its limitations. An analysis of EMS behavior revealed frequent mode-switching between EV and battery charging modes near SOC thresholds, which, while effective in conserving fuel, may not reflect realistic hybrid operation. The study concludes that rule-based EMS can provide substantial benefits in fuel economy and cost efficiency but also underscores the need for adaptive strategies and more realistic battery behavior modeling in future work.
