PRIMOVE: First Affordable Automotive Wireless Charging System Starts Serial Production

摘要

This paper supplies a comprehensive technical and economic picture of the requirements of bringing wireless charging to an automotive mass product, using the inductive PRIMOVE charging system for electric cars as an example. This system overcomes all technical constraints to ensure an efficient, safe and automatic inductive charging process. Furthermore, the paper presents the advantages of an inductive charging system with a moving part in the ground coil in comparison to a solution with larger air gaps. Together with the interoperability between different power classes, these are key factors in leading to the PRIMOVE 3.6 kW charging system being a lean solution which is ready for serial production already today. Moreover, challenges when developing a wireless charging systems e.g. positioning or metal object detection will be described and the respective solutions will be presented. The need for a neutral standardization approach and an open dialogue and collaboration in the industry, e.g. an open coil design approach, as a key factor for the success of any new charging approach is pointed out. Finally, convenient and affordable e-mobility.
