Abstract
This paper presents the simple yet effective phase shift control to attain constant current/constant current (CC/CV) charging for Electric Vehicle (EV) battery packs through series-series compensated resonant inductive wireless power transfer (RIWPT). The Series-Series (SS) compensation is mainly used in the proposed system to improve power transfer capability, reduce the leakage magnetic flux, and thereby maximize the power transfer efficiency. The battery pack of EV s is characterized as an equivalent variable resistance during CC/CV charging based on a real charging profile of a Chevy bolt EV battery pack. The primary side control is utilized in the proposed system to reduce the weight of the onboard power electronics converter and components requirements on the secondary side. An effective phase shift control strategy for RIWPT -based level 2 charger which only requires battery voltage and current data is implemented to achieve CC/CV charging of the EV battery pack. The effectiveness and practicality of the proposed control strategy are verified through a 7.7 kW RIWPT-based charger simulation as well as its experimental validation with a 3.7 kW RIWPT -based charger prototype.

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
