Three Phase High Power Integrated Battery Charger for Plugin Electric Vehicles
Bibliographic record
Abstract
Battery chargers for plugin electric vehicles can be costly and add to the weight and volume of the vehicle when designed to be on-board. Conversely, integrated battery chargers not only re-use the already available components on-board but also provide a higher charging power capability than their dedicated counterparts. Such chargers use the traction motor's windings as input filter when connected to the three-phase supply. Surface mounted permanent magnet motors have not been used for integrated battery chargers for the apparent risk of rotor movement while charging. This paper demonstrates the use of a surface mounted permanent magnet motor to charge the battery while identifying the limiting factors of its implementation. The maximum torque (70Nm) developed on the rotor while charging is calculated using an FEA model of the motor and is found to be within the limits that a vehicle can withstand. Efficiencies up to 97% with an acceptable THD was achieved with a scaled down power version of the charger.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
