Adaptive Random Search Algorithm Based On-Board Charger for WPT Based EV Battery Charging

The recent advancements in the EV charging infrastructures, different new charging scenarios are being adopted, one of them is the wireless power transfer (WPT) charging system. It gains its importance because of the absence of physical cables and making the charging procedure sophisticated. Apart form its easiness to its user it got its challenges while charging due to the misalignment's occur during Inductive WPT charging. Hence a very smart control strategy should be implemented for the reliable charging of the EV battery. So, in this paper focused on a Heuristic Algorithm based controller which maintains a constant DC voltage at the battery terminals irrespective of the misalignment's condition of the coupled coils. This paper adopted Adaptive Random search (ARS) Algorithm for optimizing the controller parameters for different scenarios of misalignment's and a detailed detailed closed loop operation of the controller is analyzed.
