vehicle 12 in accordance with the primary coil 2 the secondary coil 11 has a ferrite body 13 and is connected to a rechargeable battery of the vehicle 12 energy is transmitted across an air gap 15 or clearance beneath the vehicle 12 the primary coil 2 is integrated in a ground surface 14 so that the electrical energy storage device of the vehicle 12 is charged when the vehicle 12 is parked on the ground surface 14 adaptation to the actual lateral parking position of the vehicle 12 can be performed by the plurality of coil taps 6 7 in the region of the end sections 4 5 of the primary coil 2 efficient charging which exhibits low losses can take place only when the primary coil 2 and the secondary coil 11 are positioned virtually congruently fig2 shows the operation of the apparatus 1 when the vehicle 12 is parked to the left of the optimum position in this case the switches 8 9 are controlled by the control device 10 such that coil taps 6 7 which are located approximately beneath the secondary coil 11 of the vehicle 12 are selected the field concentration 16 produced as a result shows that the offset in positioning can be compensated for by the switches 8 9 that is to say the actively used sections of the primary coil 2 are adapted and adjusted in accordance with the position of the parking vehicle 12 fig3 shows a similar illustration to that in fig2 but the vehicle 12 is parked virtually centrally above the primary coil 2 accordingly coil taps 6 7 which are selected by the control device 10 are.
