Power Coordination System between Multiple Sources in Electric Vehicle Application

Abstract

This study presents a power management scheme for application in hybrid electric vehicle (EV) systems. For various advantageous features like, high efficiency, and high reliability photovoltaic (PV) system is chosen as the main power source of EV. However, according to mitigate the intermittency problem of solar cell, auxiliary source is required to be incorporated along with PV. Hence, an energy storage system (Battery) is associated with the PV system which can ensure an uninterrupted power supply. Through the bidirectional DC-DC converter battery cells are used to store excess solar energy and provide them to the load when required. As per requirement the battery is charged and discharged by controlling the operation mode of the bidirectional converter i.e. bucking and boosting, respectively. The MATLAB simulation results are presented to show the behavior of the responses even in presence of variation in load as well as in different illumination condition of PV module.
