Abstract
An induction charging method is provided, with a charging device being equipped with a charging capacitor comprising two opposing electrodes or plates. The device to be charged, a hearing aid or a hearing aid remote control, is introduced between the two electrodes into the electrical field of the capacitor. For energy coupling, the device to be charged is itself equipped with a capacitor which forms induction charges in dependence on the electrical field. The capacitor in the hearing aid or the hearing aid remote control can be manufactured very compactly from foils or coatings so that a significant amount of installation space can be saved for the inductive charging compared to magnetic receiving coils.
