Abstract: An induction charging device and a method for inductively transmitting energy to an induction rechargeable battery device, with at least one primary oscillating circuit that includes at least one charging coil, and with a control/regulation unit for controlling the primary oscillating circuit with an inverter circuit. An excitation frequency of an output signal of the inverter circuit made up of half-waves essentially corresponds to a resonant frequency of the primary oscillating circuit. The induction charging device provides that, for reducing a charging current, the control/regulation unit, after an end-of-charge voltage of the induction rechargeable battery device is reached, controls the inverter circuit so that the output signal periodically sets at least one first half-wave to a high value, and an odd plurality of successive half-waves is then immediately set to a value that is low compared to the high value.
