Abstract
This paper provides an efficiency model of a 7.7 kW inductive wireless charging system based on the variations in transmitting and receiving coil alignment. The design and selection of electrical and geometrical parameters for the proposed model have been outlined. The 490 mm diameter magnetic couplers were simulated at an air gap of 165 mm. The system achieved 97% coupler-coupler efficiency under ideal conditions and zero misalignment. The performance of proposed couplers were investigated for 45 mm, 90 mm, 180 mm and 250 mm horizontal displacement in 3D finite element analysis. This model operates at a switching frequency of 85 kHz and employs a single capacitor series-parallel resonant compensation to minimize the VA rating of the supply and to maximize the power transfer capability. The prototype follows the SAE J2954 specification for a level 2 wireless power transfer system.

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
