A Systematic Review of Dynamic Wireless Charging System for Electric Transportation

Abstract

Green electricity and green transportation are the primary requirements for smart cities. Maximizing the EV utilization is the key requirement in the development of green transportation. However, the EV technology faces challenges due to the long battery recharging time and heavy batteries to achieve extended driving ranges. Different approaches are investigated to charge the EV by battery swapping, plugin or wireless. Recently the wireless charging approach is gaining popularity because of safety, extended driving range, dynamic charging and human intervention free recharging. However, multiple factors need to considered in the design of WPT system and requires expertise in different domains. This paper discusses a systematic approach on the various parameters involved in a dynamic wireless charging system design. The major functional units in WPT such as charging couplers, compensation network, and power inverters topologies are addressed. Additionally, this paper discusses the issues involved in grid-tied and renewable integrated dynamic charging systems. Moreover, the step by step procesdure is described to understand the process involved in the dynamic charging system design. Finally, various case studies at different power levels are presented to get more insights into practical design.

Challenges and Barriers of Wireless Charging Technologies for Electric Vehicles

“…Electrical energy storage technology improvements have increased the power and mass of energy generated, making it possible to meet automotive demands [267][268][269]. The primary shortcoming of these storage options is the high cost of manufacture [270]. To minimize the overall cost of EVs, experts have been working to develop effective storage solutions and improve their reliability and charging strategies.…”

A novel digital control scheme for power management in a hybrid energy-source environment pertaining to electric vehicle applications

“…However, the major requirement in the establishment of charging stations to meet the battery needs indirectly increases the power expectations from the grid. The number of charging stations and energy storage devices determines the pile-up of the EV sector in a country (Shanmugam et al, 2022). For IC engines, charging the battery typically takes much longer than filling the fuel tank.…”

Wireless Chargers for Electric Vehicle: A Systematic Review on Converter Topologies, Environmental Assessment, and Review Policy

“…This radiation can take the form of microwaves or lasers. This study focuses on the magnetically coupled WPT for any electric vehicle charging application and has made the subject of a significant amount of research [3][4][5][6][7][8]. In terms of its operational modes, a WPT can be of two categories: (1) static WPT, which involves charging the battery while the vehicle is parked, and (2) dynamic WPT, which involves the battery being charged while the vehicle is moving down a roadway that is enabled for WPT.…”
