A METHOD, A DEVICE, A SYSTEM, A COMPUTER PROGRAM AND A COMPUTER PROGRAM PRODUCT FOR DETERMINING INFORMATION ABOUT EFFICIENCY OF AN INDUCTIVE CHARGING SYSTEM, HAVING A PRIMARY COIL EMBEDDED IN A ROAD INFRASTRUCTURE

摘要

The invention concerns a method f or dete rmining information about efficiency of an inductive charging system having a primary coil (101, 112), in particular embedded in a road infrastructure (100), wherein a first inductive coupling efficiency component attributed to said road infrastructure is determined from a total efficiency depending on a second inductive coupling efficiency component attributed to a position of a secondary coil (102) relative to said primary coil (101, 112) and of a third inductive coupling efficiency component attributed to an electric circuit comprising said secondary coil (102).
