Energy Management of Dual-Sources Electric Vehicles Using Adaptive Low-Pass Filter

The electric vehicle (EV) is typically regarded as the most practical solution to environmental issues. However, this green vehicle has several significant issues, including autonomy, size, battery expense, and a short battery lifetime. Supercapacitors (SC) offer energy performance that makes it possible to go around the constraints of batteries. It can be utilized to create a Hybrid Energy Storage System (HESS). The Energy Management Strategy (EMS) has a significant role in HESS to make sure that the energy is distributed optimally. In this study, the Adaptive low-pass filter (ALPF) is proposed to improve the performance of the fixed cut-off LPF method. The simulation test shows that compared to the battery-only EV, the HESS with ALPF can reduce the peak current by up to 24.00%. Whereas ALPF can use SC power more effectively compared to LPF with lower peak current.
