Analysis of multi-power sources energy management system for electric hybrid vehicle

This paper presents a new energy management system (EMS) for small hybrid electric vehicle (HEV), which utilizes energy from the combination of battery, fuel cell (FC) and super capacitors (SC). These alternative energy sources are excellent potential solution to the ever-rising price of petrol. The major focus of this paper is the energy management system, which consists of a strategy to coordinate the three different sources. This novel strategy for small HEV allowed the model to meet various load demand condition of an electric scooter or any three-wheeled vehicles. The model is simulated in MATLAB SIMULINK and its performance is analyzed by using the European test drive cycle (ECE-47). The simulation model system includes three renewable energy sources, EMS, DC machine, vehicle speed and feedback control system. The comparison result shows that the model capable to perform the proposed driving cycle.
