State of the art

Inductive energy transmission has been in use for many years. The main application is inductive charging, also known as wireless charging, for example for electric toothbrushes.

In recent years it has also gained more and more importance for smartphones, tablets and accessories such as headphones.

In addition to charging, direct operation of a power consumer is also possible. Consortia (e.g. Wireless Power Consortium and Power Matters Alliance) created the framework for widespread use of uniform standards.

Solutions are known in which a charger, preferably in a round shape, is supplied with power via a round cable with a power supply unit. Due to the design, the height of the devices is usually 20mm and more.

Solutions in which the charger is integrated into furniture, lamps, thick mouse pads, etc. are also known.

Solutions are also known in which a piece of furniture is retrofitted with charging stations. For this purpose, holes are drilled in the piece of furniture, in which a conventional charger is then installed. Often this is done from below, so that the charging station is not visible from above. Due to the remaining layer of the piece of furniture, there is a gap between the transmitter coil and the receiver coil of the power consumer or power store, which has a negative effect on the performance of the energy transmission. Solutions such as ENERQi are also being developed, which state that they can be installed on table tops up to 4 cm thick without drilling and still provide sufficient charging capacity.

In the case of solutions with a transmitter coil, there is the challenge of precise placement, since if the transmitter and receiver coil overlap too little, the charging power is lower or no charging takes place at all.

Solutions are known in which an area is reliably covered in that several coils are operated on a suitably equipped transmitter electronics module, and the most suitable coil is then used for the energy transmission.

Solutions are also known in which several individual transmitter coils, each with a transmitter electronics module, are used for the transmission of energy to reliably cover an area. With this solution, several power consumers or power storage devices located on the energy transmission surface can be supplied at the same time.

Using multiple coils with a transmitter electronics module, and even more so using multiple coils, each with a transmitter electronics module to cover a larger area, is inefficient and expensive.

During operation, high temperatures can arise which have a negative effect on the service life of the electronic module of the transmitter coil, which is spatially close to the transmitter coil, and also of the receiver coil and possibly also of the power consumer or the power storage unit.

Electronically operated small means of transport such as eBikes and electric scooters are known. The big challenge is charging the batteries. In the case of devices with built-in batteries (e.g. electric scooters), the entire means of transport must be brought to the socket. With other means of transport, the battery must be removed and then charged at the socket. Both are time-consuming, on the one hand, and wear and tear and often damage on the other, which have a negative effect on the service life.

In the rental equipment sector, there are significant costs for service providers or their own personnel for charging or replacing batteries.

Since the batteries are often empty during the day if they are rented frequently, but charging usually only takes place overnight, the availability is not optimal with lost sales and insufficient customer satisfaction as a result.

Concepts are known to charge electric cars by means of inductive charging stations and receiver coils built into the floor pan of the body or underneath. Here, the receiver stage is placed over the transmitter coil in a targeted manner.

task

It is the object of the invention to provide a method, a system and a device in which one or more power consumers or power storage devices are inductively supplied or charged with power efficiently and inexpensively.

It should be possible to cover a larger energy transfer area with a small number of transmitter coils, each with a transmitter electronics module or several transmitter coils with commonly used electronics modules by means of inductive energy transfer.

The loss of power should be kept low by the small distance between the transmitter coil and the receiver coil of the power consumer or power store.

The load on the electronic module or modules of the transmitter coil or transmitter coils and the power consumer or power storage device is to be kept low or avoided entirely by means of thermal management.

An energy transmission system should be configured for the ideal power supply or charging capacity.

The transmission part of the energy transmission system should have a low overall height for greater user-friendliness.

There should be designs in which the assembly of the transmitter part of the energy transmission system can also be carried out for non-skilled workers.

These objects are each achieved with a method, a system and a device having the features according to the independent patent claims. Advantageous embodiments and applications of the invention emerge from the dependent claims.

In a preferred embodiment, one of the established standards that are currently being developed is used for the energy transmission system, but qi of the Wireless Power Consortium should be mentioned here as an example but not conclusively.

In a further preferred embodiment, different standards are available at the same time.

In a further preferred embodiment, a proprietary energy transmission system is used.

The invention also includes an energy transfer system that is used for inductive energy transfer for one or more possible power consumers or power stores with targeted positioning of at least one receiver coil and comprises at least one energy transfer surface, a transmitter coil, a transmitter electronics module and a power consumer or power store with a receiver coil.

In a preferred embodiment, part or the entire underside of the device for energy transmission is three-dimensionally adapted to the support surface in order to achieve a good connection, greater stability, greater durability and less maintenance. In a preferred embodiment, the adaptation is achieved by means of a 3D-printed layer. In a further preferred embodiment, this is done by means of flexible material or with foam. In further explanations, this is done with other means, examples but not conclusively mentioned are adhesive, bags filled with liquid, bags filled with hardening liquid, bags with granules that are evacuated.

In the preferred embodiment as an energy transmission system for electric scooters, the position of the electric scooter in public space is controlled in a targeted manner. Electric scooters are delivered to the energy transfer areas. In the preferred embodiment, this is actively encouraged. Exemplary, but not conclusive, are incentives as part of a discount and a system with micro-juicers that bring scooters to energy transfer areas under a defined charge level in return for an expense allowance.

In the preferred embodiment, the energy transfer surfaces are placed at attractive locations, which can be, for example, traffic junctions, restaurants or places of interest.

In a further preferred embodiment, areas are designated by the municipalities in order to actively manage traffic and parking.

The energy transmission surfaces can be supplied with electricity in many ways. Examples but not conclusively are: restaurants, retail, local public transport, utility companies (for example via a power connection in the lamppost), city administrations or private residents.

The motivation to offer energy transfer surfaces is diverse. The following are examples but not exhaustive: support for emission-free means of transport, advertising opportunities, commission and / or loading fee, customer acquisition.

In a preferred embodiment, the user is motivated to move the power consumer or power storage device into a specific position and / or orientation on the energy transmission surface in order to reduce the effort required for determining the position. In the preferred embodiment, this is achieved by means of measures and devices, the following examples, but not conclusively, may be mentioned for this purpose: graphic information and / or writing, elevations, depressions, obstacles, lights, noises.

In the preferred embodiment, when the user provides the consumer with a suitable energy transfer to the energy transfer surface, a short or permanent signal, which can be of an optical and / or acoustic nature, and / or a vibration, and / or a radio signal, and / or occurs a different type of signal, or a combination of at least two of the signals described. This signal, which can also be the user's favorite song, for example, is intended to motivate the user to position the consumer appropriately for the energy transfer process. In a further preferred embodiment, the appropriate position is specifically determined and specified accordingly, for example, to fill up loading bays of scooters without gaps or to fill them up so that scooters with a high charge level are more on the outside, where they can be picked up more quickly while those with a low charge level are in inner area and tend to have a longer loading time available. Measures for this are mentioned as examples but not conclusively: short or permanent signal, which can be of an optical and / or acoustic nature, and / or a vibration, and / or a radio signal, and / or a different type of signal, or a combination of at least two of the signals described.

In a further embodiment, the power consumer or power storage device can only be brought into a certain position and / or orientation or in a small number in certain positions and / or orientations due to the design. As an example, but not exhaustively, its areas with depressions and / or walls, devices with stands and / or hooks and / or locking devices, slides and slides are mentioned here. The transmitter coil and receiver coil can then be appropriately positioned on the basis of the position or the respective predefined and fixed positions of the consumer so that a reliable energy transmission is achieved.

In a preferred embodiment there is an energy transmission system in which the cavity in the middle of the transmitter coil and / or receiver coil is filled with a ferrite and / or MU metal or another material with a high magnetic permeability and / or the transmitter coil and / or Receiver coil is thus partially or completely enclosed.

In the preferred embodiment, the material with the high magnetic permeability extends into both the transmitter coil and the receiver coil and thus has at least the height of the transmitter coil plus the height of the receiver coil. In a further embodiment, the height of the material with the high magnetic permeability is designed differently.

In a further embodiment, especially for small electronic means of transport, there is no determination of the position of the receiver coil of the power consumer or power store, no determination of whether the receiver coil of the consumer can already be operated by a transmitter coil and no positioning of the transmitter coil to match the receiver coil, but a check to determine whether the receiver coil is sufficiently close to the transmitter coil for the energy transfer and, if the result is positive, the start of the energy transfer from the transmitter coil to the receiver coil. Instead, the method includes the step of the stationary positioning of the device and thus the transmitter coil.

This is done, for example, in that the means of transport is locked in a stand with the front or rear wheel. The receiver coil is integrated into the wheel or some other fixed part; The transmitter coil is positioned accordingly in the stand.

Another component is a method for inductive energy transmission for one or more possible electricity consumers or electricity storage devices with targeted positioning of at least one receiver coil, the method including the following steps, both in their entirety and in relation to the individual steps, once or several times in this or changed Order to be executed:

• - Electricity consumer or electricity storage comes to the energy transfer surface
• - Locally stable positioning of the power consumer or power storage and thus the receiver coil to match the transmitter coil
• - Determination of whether there is a power consumer or power storage on the energy transfer surface
• - Identification and / or authorization
• - Check whether the receiver coil is sufficiently close to the transmitter coil for energy transmission
• - Start of the energy transfer from the transmitter coil to the receiver coil
• - Electricity consumer or electricity storage leaves the energy transfer area
• - End of the energy transfer from the transmitter coil to the receiver coil
• - Transmission of data

In a preferred embodiment, positioning takes place along the Z axis. The distance between the transmitter coil and the receiver coil is reduced by a method or a device.

Not all steps of the method are carried out in further statements. For example, identification and / or authorization can be dispensed with in a concept in which the electricity for charging is made available free of charge. In this case, a process step for billing is not necessary.

In the preferred embodiment, the surface of the energy transfer surface is used for a further application. As examples, but not conclusively, the following are mentioned here: advertising, notice.

In the preferred embodiment, the receiver coil is integrated into the part of the means of transport that is in direct contact with or at a short distance from the ground. In the preferred embodiment, the receiver coil is integrated into the stand of the vehicle. In a further embodiment, an extra device is used for this.

As an example, but not conclusively, this is explained using the example of an energy transmission system according to the invention for charging electric scooters: the receiver coil is built into the stand of the electric scooter in such a way that it is flat on the ground when the stand is unfolded and thus flat when positioned correctly is on the transmitter reel. This can be done by modifying the existing stand or retrofitting an appropriately equipped replacement stand. From there, the cable (s) to the battery of the electric scooter or the electronics that are used to charge the battery of the electric scooter or the charging plug (s) are routed and connected.

In the preferred embodiment, a receiver coil and / or a transmitter coil is used in which the winding geometry is not designed horizontally flat, but is stretched vertically. In a preferred embodiment, this takes place in the form of a cylinder coil. In other preferred embodiments, this is done in the form of a cone or a pyramid. In further versions in other configurations.

The invention also includes an energy transfer system in which the back induced energy when the induced voltage is switched on and off, it is used to charge electrical storage devices such as capacitors and / or batteries and / or to convert it into another kinetic and / or magnetic and / or mechanical force.

In a preferred embodiment, the energy transmission system is also equipped with a device for data transmission. Examples but not conclusively are: Near Field Communication, Bluetooth, WLAN, other radio technologies, optical and acoustic systems.

In this way, data from the consumer can be transmitted with little energy - using the example of an electric scooter, the charging status and change, position, distance traveled, temperature, state of wear and tear - can be transmitted and then evaluated.

In a further embodiment, mobile connections, broadband connections or other wired technologies are used.

The transmission of data, for example identification of the electric scooter, charging time, transmitted energy and subsequent evaluation, can also be used to create a consumption-based billing. It is also possible to carry out remote maintenance using the transferred data and to operate an active battery management system.

Alternatively, conversely, data from the charging station can also be transmitted to the consumer. The reason for this is given as an example but not conclusively: the charging station is not connected to a backbone and not to the cellular network, whereas the consumer is.

Advantages:

The invention leads to the fact that the battery of mobile devices is empty less often and thus the devices have a higher availability.

The invention enables reliable energy transfer to one or more consumers with a larger energy transfer area without the user having to position his device exactly.

In a further version, the user is supported in placing the device exactly.

Due to the design, a low overall height can be achieved, so that a less disruptive application is possible.

In the field of small means of transport, the application is a significant gain in comfort - carrying electric scooters or removing and carrying the battery to the socket is no longer necessary. Wear and damage resulting therefrom are no longer applicable.

Through this and the mechanical or reflection-controlled solution, the invention is climate-friendly, resource-saving and effective.

In the rental of electric scooters, considerable cost savings can be achieved in the charging service. A longer service life through underground charging combined with higher income and higher customer satisfaction is achieved.

The motivation to park the small means of transport on the designated energy transfer areas can avoid disruptions (means of transport lying around wildly) and achieve a high level of availability at the desired locations with a high frequency of use.

Sustainable, climate-friendly operation and active parking management of the electric scooters lead to improved acceptance by the public and by authorities.

Due to the adapted underside of the energy transfer surface, a good connection with the support surface is achieved, which results in greater stability, greater durability and less maintenance.

The design of the coils and the shield enables higher efficiency.

With the data transfer function, evaluations can be created comfortably in order to improve the system.

Further advantages and details of the invention will become apparent from the description of the accompanying drawings.
