Energy Management System Enhancement for Electric Vehicle Application

Following the drawbacks of battery-powered electric vehicles, multi-energy source electric vehicles are one of the most promising technologies for urban transport. Whatever the vehicle dynamics, the control of energy and the specific power of each source is a very tricky task. For such systems, effective energy management is necessary to provide the best possible power distribution among the various sources and loads. In this study is which based on Tesla model S electric vehicle, boost DC-DC converter is used to link a fuel cell to the DC bus and A buck-boost DC-DC converter is used to connect a battery and supercapacitor to the DC bus. To get minimal fuel consumption, we were used three levels frequency separator and PID fractional order to control DC-DC converters. Digital simulation with MATLAB/Simulink for all vehicle power train is realised applying such strategy.
