The present invention relates to a system (1) for inductive energy transfer, in particular to a mobile application (100), which system comprises: a stationary induction charging device (2, 2a) having a stationary energy coil (3, 3a); and a mobile induction charging device (2, 2b) having a mobile energy coil (3, 3b). Precise and reliable determination of the relative position of the energy coils (3) in relation to one another is achieved by means of a positioning device (4) which has, in one of the induction charging devices (2), at least four transmission coils (5) and, in the other induction charging device (2), at least one receiver (6), wherein the transmission coils (5) generate mutually distinguishable positioning fields (60) which interact with the at least one receiver (6), wherein the ratio between the positioning fields (60) is used to determine whether the energy coils (3) overlap one another. The invention also relates to an induction charging device (2) of this kind and to a mobile application (100), in particular a motor vehicle (101), having a mobile induction charging device (2, 2b) of this kind.
