1. A charger for a portable device deployed in a motor vehicle, the charger comprising:
- a resonant circuit configured to inductively transmit energy from the motor vehicle to the portable device; and
an actuation apparatus configured to control the resonant circuit, wherein the actuation apparatus provides input to the resonant circuit with a curve shape selected from a set of predetermined shapes, a particular curve shape chosen from the set of predetermined shapes based at least in part on an operating state of the motor vehicle;
each particular curve shape in the set of predetermined shapes defined differently from the other shapes by more than amplitude and frequency.

Abstract
A charging device for a portable device, e.g., in a motor vehicle, includes a resonant circuit, controllable by a trigger device, for inductive transmission of energy to the portable device, wherein the trigger device is designed such that the curve shape of the excitation for the resonant circuit is generated based on an operating state of the charging device.
