OPTIMIZATION CONTROL IN HYBRID ELECTRIC VEHICLE FOR ITS ENERGY MANAGEMENT

In electric vehicles, the battery's low life span is the primary concern for manufacturers worldwide as the battery is the only energy source. A hybrid electric vehicle (HEV) consisting of two or more energy sources with proper energy management and power management is the solution for better fuel economy and lower tailpipe emissions. The main scheme of energy management strategy (EMS) is to split energy between these sources to reduce fuel consumption and to attain utmost power utilization. EMS can be Rule Based or Optimization Based Strategy. In this paper, some energy management strategies are employed to determine the output of different energy sources and different EMS is applied to the model to lessen the fuel consumption of vehicle. The simulation for all the strategy is performed by using MATLAB/Simulink.
