Definitions

• the invention relates to the use of so-called
• Road-going electric vehicles are connected to a charging station in the current state of the art by means of a connection made from a plug to a mating coupling.
• stations with appropriate cables are provided.
• the object of the present invention is to provide such a Lö ⁇ solution, particularly advantageously solves these requirements. This object is solved by the features of claim 1 and the features of claim 6.
• a pancake coil is used for the wireless transmission of energy to an electric vehicle, wherein at least a first coil of the coils required for transmission is designed as a pancake coil for wireless transmission.
• pancake coils are compact and at the same time flat keptstal- tet, wherein the individual coils a high quality aufwei ⁇ sen, increases the efficiency of energy transfer.
• pancake coils which is characterized in that it is 2-layer spiral coils of stranded wire same sense of winding, with a first coil, in a ers ⁇ th location from outside to inside wound and a second coil is wound in a second layer from the inside out.
• the use is putge ⁇ forms such that, for the use of the pancake coil, layers of the first coil are arranged separated in a voltage-resistant manner.
• This distinctive ⁇ net in particular by stable storage of the coils but also by optimizing the energy transfer function.
• Derivatives here are defined as composites designed for use as circuit board material.
• this may be realized such that the tension resistive separate arrangement of the first coil, a Teflon film is mounted between the layers.
• a Teflon film is mounted between the layers.
• the pancake coil of the invention is arranged on egg ⁇ ner, in particular designed as a plate, ferrite.
• the ferrite arrangement is structured as a plate. This increases the inductance and thus minimizes the winding volume. Furthermore, such a ferrite bottom forces the (electro) magnetic field into the field of the other half space of the field or restricts the (electro) magnetic field to a total of one half space.
• an arrangement for the wireless transmission of energy to an electric vehicle is proposed, which is characterized in that a charging station and / or electric vehicle is designed such that it is equipped with a described uses described above
• Pancake coil is configured.
• Figure la is a plan view of a first position
• figure lb is a side view according to theticiansbei ⁇ play of the invention for power transmission to be used pancake coil.
• FIGS. 1 a and 1 b like all variants according to the invention, has the
• Pancake coil on the advantage that they ensure the inductive charging of vehicles (or their batteries) that the power-transmitting coils or by arranging two such coils, ie a vehicle in the vehicle and a charging station formed transformer system, if possible low-loss is executed.
• a second requirement in the design of the coil system that fulfills the use according to the invention is the size of the individual coils, which are to be made as compact and flat as possible.
• PANCAKE_SPULE_LAGE_2 of the pancake coil are configured as double-layer spiral coils of stranded wire with the same winding sense, wherein the first coil PANCAKE_SPULE_LAGE_1 is wound in the first position from the outside to the inside, and the second coil PANCAKE_SPULE_LAGE_2 is wound in the second layer from inside to outside.
• the voltage-proof doors ⁇ voltage of the two layers by a thin composite sheet for example, FR4 board, FR_4_PLATTE is given.

• Alternatives to this or additions are Teflon film or paints.
• the stranded wire at the end of the first winding passes through a bore in the composite plate FR_4_PLATTE to the other layer side of the composite plate FR_4_PLATTE. It can also be seen that this arrangement is mounted on a ferrite plate FERRITPLATTE.
• the coil losses can be at least minimized by the design according to the invention as described here.
