Abstract
In a process for contactless energy transmission in charging the battery of a vehicle, in particular an electric car, by means of an inductive transmitter having a primary element (1) and a secondary element (2) which is attached to the vehicle, the secondary element (2) is made freely accessible and the primary element is power driven to move in all three spatial coordinates within a predetermined spatial area. In this process the primary element (1) and the secondary element (2) are placed, under sensor control, in predetermined positions relative to each other and then electrical energy is transmitted in the medium frequency range by means of the inductive transmitter.
