Abstract
To provide safe and flexible power transfer to electric vehicles (EVs), wireless charging systems have been introduced. By improving the overall system efficiency of wireless charging systems for EVs, the range anxiety of EVs can be significantly reduced. In this paper, a comparative characteristic analysis is carried out between circular and double D (DD) power pads for EV wireless charging systems. The Society of Automotive Engineers (SAE) recommended practice J2954 is followed for designing physical dimension of these power pads. Finite Element Analysis (FEA) tool ANSYS Maxwell 3D is used for simulation. Parameters such as coupling coefficient and mutual inductance are evaluated for each type of power pads by applying vertical and horizontal misalignment. It is found that DD power pads exhibit promising characteristics for EV wireless charging systems.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
