To achieve accurate prediction of the nonlinear behavior of lithium-ion batteries, parameters of the lithium-ion battery model play a key role for dynamic performance, hence the parameters of the proposed battery model have been estimated. For this work, performance level testing has been carried out.

The study shows RDG (Renewable Distributed Generation) and CB (Capacitor Banks) integrated system has minimized power loss and enhanced voltage profiles than RDG integration alone. By integrating RDG, the performance of RDS is further enhanced which results in minimizing the amount of Energy Not Supplied (ENS) provided.

An efficient wireless topology for electric vehicle battery charging

2021

Author(s): Nama, J K

Recent studies on the topological framework of IWPT system declines required adapt ability and performance for regularly updating EV battery technology. Some of the identified regions include variations of the battery voltage, capacity, and management system for the light load (personal) to heavy load (passenger vehicle); adopted topology for on-board operation; topological limitations for control and gating scheme. These reasons have promoted academia and industry-wide efforts to acquire a flexible and adoptable IWPT technology for future EVs.

ATC- based (available transfer capability) CM (congestion management) has been used in this thesis to relieve the congestion of the system. To enhance the ATC value, the integration of a wind battery system has also been used. Technical challenges i.e., selection of critical zones, optimum location for WPG and BESS, ATC enhancement using proper charging/discharging of battery in a wind battery system, and CM have been considered.
