7. A method for controlling a charging operation of a rechargeable energy store which has a first induction coil with the aid of a charging device having a coupling surface for positioning the energy store and a second induction coil for generating a magnetic field in the area of the coupling surface to transmit electrical energy between the first and second induction coils, the method comprising:
-
determining a first electrical power transmittable between the first and second induction coils; changing the alignment of the magnetic field of the second induction coil in relation to the alignment of the first induction coil; determining a second electrical power transmittable between the first and second induction coils; comparing the first electrical power transmittable between the first and second induction coils to the second electrical power transmittable between the first and second induction coils; and changing the alignment of the magnetic field of the second induction coil on the basis of the comparison to maximize the electrical power transmittable between the first and second induction coils. - View Dependent Claims (8, 9)
