Abstract
This paper presents the wireless power transfer (WPT) technology based on inductive coupling and the design challenges of a hybrid energy harvester (EH) circuit as a promising solution to promote the energy efficiency of the electric vehicles (EVs). The design methodologies of ultra-low power electronic module based on low leakage conditioning and processing device are details based on nanoscale transistor technology so that the WPT and hybrid EH can be implemented for self-powered devices in EVs.
