“…The Tx coil current also contributes to the loss because of the external proximity effect, which is dissipated in the Rx coil 6 ; eddy currents are created in the Rx coil from the timevarying magnetic field from the Tx coil current. The eddy current can be modeled as an independent winding [33], [34] that is electromagnetically coupled to the Tx coil.…”

Wireless power transfer is emerging as the preeminent way to charge electric vehicles, but there appears to be no fair way to measure the power transfer. In this paper, Faraday Coil Transfer-Power Measurement (FC-TPM) is presented. FC-TPM employs non-contact, open-circuited sense coils to measure the electromagnetic field from wireless power transfer and calculates the real power propagating through the air gap between the transmitter and receiver coils. What is measured is the real electromagnetic power, representing the pure dispensation of energy that unambiguously demarcates the losses on either side. FC-TPM was demonstrated to be 0.1% accurate in hardware over an Rx coil misalignment of up to 10 cm using a 1 kW wireless power transfer system. Fair metering incentivizes businesses and individuals to make choices that conserve energy and advance technology by providing more information and by properly assigning the financial loss. This paper is accompanied by a video highlighting the essential contributions of this paper.

Analysis of Dynamic Wireless Power Transfer Systems Based on Behavioral Modeling of Mutual Inductance

This paper proposes a system-level approach suitable to analyze the performance of a dynamic Wireless Power Transfer System (WPTS) for electric vehicles, accounting for the uncertainty in the vehicle trajectory. The key-point of the approach is the use of an analytical behavioral model that relates mutual inductance between the coil pair to their relative positions along the actual vehicle trajectory. The behavioral model is derived from a limited training data set of simulations, by using a multi-objective genetic programming algorithm, and is validated against experimental data, taken from a real dynamic WPTS. This approach avoids the massive use of computationally expensive 3D finite element simulations, that would be required if this analysis were performed by means of look-up tables. This analytical model is here embedded into a system-level circuital model of the entire WPTS, thus allowing a fast and accurate analysis of the sensitivity of the performance as the actual vehicle trajectory deviates from the nominal one. The system-level analysis is eventually performed to assess the sensitivity of the power and efficiency of the WPTS to the vehicle misalignment from the nominal trajectory during the dynamic charging process.

“…Estimates suggest that there will be over 250 million electric vehicles (EVs) by 2030 [2]. The growth of EVs has led to the rapid rise of Wireless Power Transfer (WPT) for the charging of these vehicles [3]. WPT is an emerging field and promises to become a necessity in the future with the emergence of electric vehicles and increasing renewable energy generation.…”
