Design of Wireless Power Charging System for Driverless Pod Application

摘要

Driverless Pods can be classified as Electric Vehicles (EVs) which possibly represent environmentally friendly transportations. However, the battery technology is the real restriction in accomplishing this concept due to its drawbacks, for example, high cost, scarce components, weak specific energy and physical contact with charging device requirements. Besides the pursuit of materials and energy density development, wireless power transfer (WPT) technology which is another technique to charge the batteries of the EVs with no physical contact has been introduced. In this paper, an overview of WPT technologies for EVs charging has been presented including classification, compensation topologies, transformer structures and different charging control techniques. Then, A MATLAB Simulink model is used to simulate the load identification method in order to validate this technique which seeks to achieve a constant voltage charging through load identification depending only on the primary-side controller.
