Analysis of DC-DC Converter for Energy Management in Electric Vehicle

Abstract

The aggravations occurring in Environmental pollution and the exhaustion in fossil fuels has led to the higher cost of Internal Combustion Engine (ICE) based vehicles. Hence, to overcome this critical condition, the Electric Vehicles (EVs), in which the energy storage system plays the main role is introduced. Many countries have moved forward in accepting the use of Distribution Generators (DGs) and EVs. Nevertheless, the uncoordinated charging of EVs led to significant increase in the network losses, decrease in the energy efficiency and system voltages. Hence, the PV (Photovoltaic) System, which is one of the RES (Renewable Energy Sources) is integrated with EVs, so as to eradicate all the above stated issues.  However, charging complexities occurs, owing to the intermittent nature of solar system. Therefore, Power electronic converters, along with different controllers are employed for regulating the PV output in EV charging system, in consideration with the economy, as well as the reliability of DS. In this paper, the various types of DC-DC converters employed in EV charging and the different controllers used in charging are analysed with respect to their performances and functioning characteristics. In addition, an analogization is carried out amid the different EV charging techniques, so as foreshow the optimal one.
