CharIN e.V. published a guideline for inductive charging

The Charging Initiative e.V. published an industry statement about wireless power transfer (WPT) to support the development of advanced inductive charging systems.


CharIN is dedicated to developing and establishing the Combined Charging System (CCS) as the standard for charging battery electric vehicles of all kinds. Besides the existing conductive charging systems, rules and recommendations for interoperable inductive charging systems become an urgent matter. As official standards are still in progress and affected by continuous enhancements, CharIN sees a need for common guidelines supported by the industry. Therefore, this document was published to provide guidance for interoperable inductive charging systems where standards are in development. The interoperability shall be ensured by describing a selection of existing technical solutions to be applied in a product. It should be considered as a complement document to the standards.


The industry statement covers the most relevant technical objects to define the requirements for an interoperable wireless power transfer for inductive charging of electric vehicles.

Magnetic and electric interoperability testing as well as test systems referenced in SAE J2954 are described. Moreover, the positioning, the safety concept and a common ground assembly position in the parking space are considered. The document will be the baseline for an open specification for all involved parties.
