Abstract
"In truth, WPT has at least 30 years of history with the term "IPT," using the same fundamental tenet that has already been established. The development of WPT technology has recently accelerated, with transmission distances at the kilowatt power level ranging from a few millimeters up to several hundred millimeters and a point loading efficiency of more than 90%, which applies to both static and dynamic charging environments. Due to this, WPT is particularly appealing for electric vehicles (EVs). However, the performance of wireless power transfer (WPT) systems in various WPT applications remains a significant design challenge. While the use of plug-in electric vehicles (PEVs) is growing, a technological advance is needed to address battery-related flaws. Even if battery technology is improving, the key growth barriers for EVs will continue to be price, dimensions, weight, delayed charge features, and low energy density. Additionally, many customers may not embrace PEVs as their preferred choice due to concerns about price. Dynamic wireless power transfer (DWPT)-enabled EVs have been offered as a solution to battery-related restrictions. The dynamic EV charging concept should be implemented using a WPT-capable infrastructure. As less energy storage is needed for operating the car wirelessly while driving, a battery pack can be lighter. WPT fixed charging refers to wirelessly charging the EV while it is parked, which is less complex in terms of design than dynamic WPT. In contrast to plug-in EVs, ordinary WPT does not extend the driving range of the vehicle. This chapter discusses cutting-edge WPT technology for future transportation and introduces performance indices for the WPT system."
