Abstract
Wireless/contactless charging of electric vehicles can improve the safety and convenience of the electric vehicle charging process. However, in order to enable wireless charging on an electric vehicle, additional components need to be added to the vehicle, which increase the cost, and weight of the vehicle. Specifically, a wireless receiver coil and power electronics are required to receive the wireless power and charge the battery. This work proposes a new integrated wireless charger, which reuses the existing drivetrain components, such as the traction inverters and the motor, to serve as the receiver-side power electronics for wireless charging. Importantly, this topology limits the high frequency currents entering the traction components, such as the motor, which are susceptible to high frequency losses. The drivetrain can serve to control the charging rate of the batteries, which eliminates the need for transmitter side battery charging control and communication. Experimental validation was done by coupling a 110 kW EV machine and dual-inverter drivetrain to a 6.6 kW wireless transmission system. A peak charging efficiency of 94.3% over a vertical coil distance of 200 mm was achieved.

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
