Abstract :This study proposes an advanced EMS for a SHEV equipped with lithium-ion (Li-ion) batteries and supercapacitors (SC). The developed rule-based EMS optimizes power distribution between the internal combustion engine (ICE), electric motor (EM), and energy storage system (ESS), ensuring efficient energy utilization while enhancing battery lifespan and vehicle performance. The proposed EMS dynamically adjusts power flow based on real-time driving conditions and charge state, preventing excessive charge/discharge currents and improving regenerative braking efficiency. A comprehensive simulation was conducted using the ADVISOR (Advanced Vehicle Simulator) platform to evaluate vehicle performance under Urban Dynamometer Driving Schedule (UDDS) and New European Driving Cycle (NEDC) conditions. Results demonstrate that the EMS significantly enhances energy efficiency, reduces fuel consumption, and extends battery longevity while ensuring optimal power delivery. Comparative analysis reveals superior performance under NEDC conditions due to smoother acceleration and braking patterns. These findings highlight the effectiveness of integrating supercapacitors with Li-ion batteries in SHEV architectures, providing a viable solution for sustainable and efficient hybrid vehicle design.
