1. A method for determining information about an efficiency of an inductive charging system, comprising:
- receiving an output from one or more devices that measure power transferred through one or more primary coils embedded in a road infrastructure;
receiving, from a vehicle moving on said road infrastructure, an output from another device that measures power transferred through a secondary coil located in said vehicle; and
determining a first inductive coupling efficiency component attributed to said road infrastructure from a total efficiency based on a second inductive coupling efficiency component attributed to a position of said secondary coil relative to said one or more primary coils and of a third inductive coupling efficiency component attributed to an electric circuit comprising said secondary coil.

Abstract
A technique is provided for determining information about efficiency of an inductive charging system having a primary coil embedded in a road infrastructure and a secondary coil located in a vehicle moving on the road infrastructure. A first inductive coupling efficiency component attributed to the road infrastructure is determined from a total efficiency depending on a second inductive coupling efficiency component attributed to a position of the secondary coil relative to the primary coil and of a third inductive coupling efficiency component attributed to an electric circuit comprising the secondary coil.
