A Comparison Among Lithium-Ion, Nickel-Cadmium & Nickel-Metal-Hydride Batteries for Charging and Discharging in Electric Vehicle by Bidirectional Dc-Dc Converter

This paper describes the design and simulation of the batteries which are connected in series with a DC-DC converter. In the present scenario, the demand for an electric vehicle is increasing day by day. In any electrical system that has used for storage the energy or delivering the energy, they must need a battery system. Without a good energy storage system, the electric system is incomplete. State of Charge is a very important part of a battery. When any battery is connected for charging then soc will always be increased and decreasing at the time of discharge. In this paper we are trying to discuss if the batteries are connected in series, then SOC will be affected or not. Any Liion battery is connected with a bi-directional DC-DC converter than what changes are shown in the simulation? In an electric vehicle the battery management system is playing a very important role this time. So, in our paper first, we have to discuss which batteries are most suitable for a long-term electric vehicle. We have proposed the two types of batteries and show in this paper the simulation and modeling. Simulation results show that pulse width is a very important factor to complete its work.
