Abstract: 

Hybrid Energy Storage System (HESS) has been implemented for better energy efficiency to Hybrid/Electric Vehicles (HEV/EV), in that the main source is battery and UltraCapacitor (UC) is the auxiliary source. Switching of the energy sources according to the electric vehicle speed also plays an important role, to improve the life of the battery. So designing of the controller is a dynamic factor in case of electric /hybrid electric vehicles. The main objective of this paper is to design a controller for the transition between the sources, battery and Ultracapacitor. Here controller has been designed based on the Math function coding and this can be termed as Math Function Based (MFB) Controller. The controller generates the signals to the converters based on the speed of the motor. The MFB controller mainly designed to work in four modes and for each and every mode separate math function has been created. The overall system has been simulated in MATLAB and plotted the all results with discussions.
