Wireless Power Transfer and In-Vehicle Networking Integration for Energy-Efficient Electric Vehicles

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 (ULP) electronic module based on low leakage conditioning and processing device are detailed based on nanoscale transistor technology so that the WPT and hybrid EH can be implemented for self-powered devices in EVs. Moreover, in-vehicle network design verification based on a new power-aware behavioral model formulation and extraction for high-speed and ULP transceivers that enables the transient prediction of power and ground currents and voltages when multiple drivers are simultaneously switching for signal-power integrity evaluation. The derivation of the proposed model is based on the analysis and extension of the input/output buffer information specification (IBIS). The analysis of the previous IBIS and Mpilog modeling approaches is followed by a new model formulation along with a well-designed characterization and parametric extraction procedure.
