Analysis of Charge Plate Configurations in Unipolar Capacitive Power Transfer System for the Electric Vehicles Batteries Charging

摘要

This paper analyzes the ring and square plates configurations in a unipolar capacitive power transfer (CPT) system for electric vehicle (EV) batteries charging. It is shown that the ring plates coupler provides better coupling capacitance and coefficient than the square one. In this paper, the vertical, lateral, angular and rotational misalignments were actively researched. Furthermore, the interoperability between the different plates configurations has been analyzed. The ring plate showed good compatibility only with a ring plate, while the square plate showed good compatibility with the square and disc plates.
