Description

[0001] Vehicle module and / or floor module for an inductive vehicle charging system

[0002] The invention relates to a vehicle module (CPM) and / or ground module (GPM) for an inductive charging system for charging an energy storage device of a vehicle, in particular an electric vehicle or a hybrid vehicle, wherein energy can be inductively transferred from the ground module (GPM) to the vehicle module (CPM). The invention further relates to an inductive charging system for charging an energy storage device of a vehicle, comprising at least one such vehicle module (CPM) and one such ground module (GPM).

[0003] A variety of inductive vehicle charging systems are known in the prior art, which comprise at least one vehicle module CPM and one ground module GPM and to which reference is made here.

[0004] The object of the invention is to provide a vehicle module CPM and / or a floor module GPM for an inductive charging system for charging an energy storage device of a vehicle, which is cost-effective to manufacture, reliable in its susceptibility to failure and also easy to maintain.

[0005] The invention is based on the features of the independent claims. Advantageous developments and refinements are the subject of the dependent claims. Further features, possible applications, and advantages of the invention will become apparent from the following description and the explanation of exemplary embodiments of the invention illustrated in the figures.

[0006] A first aspect of the invention relates to a vehicle module CPM and / or a floor module GPM for an inductive charging system for charging an energy storage device of a vehicle, wherein energy can be transmitted inductively from the floor module GPM to the vehicle module CPM, and the vehicle module CPM and / or the floor module GPM comprises a number N of electronic assemblies BG n , with n = 1 , 2, ..., N and N > 2, each of which is a microprocessor module MPM n , an analog circuit module ASM n and an antenna module AM n include.

[0007] The vehicle module CPM and / or the ground module GPM is characterized by the fact that for at least two modules BG n=i and BG n=2 of the assemblies BG n It is true that these identically constructed and configured microprocessor modules MPM n=1 and MPM n=2 and / or identically constructed and configured analog circuit modules ASM n=1 and ASM n=2and / or identically constructed and configured antenna modules AM n=1 and AM n=2 have.

[0008] The term “identically constructed and configured” modules is understood in this case to mean in particular that these modules are electronically and mechanically constructed in such a way that they can be used in both the one assembly BG n=i as well as in the other assembly BG n=2 are usable, ie they are mutually interchangeable. They therefore fulfill all the associated necessary requirements, functions and tasks for both assemblies BG n=i and BG n=2 The term also encompasses the meaning "physically identical." This means that the modules in question are copies of each other.

[0009] These identically constructed and configured modules reduce the manufacturing costs of the vehicle module (CPM) and / or the ground module (GPM) by reducing the variety of module types. At the same time, the susceptibility to errors is reduced by using fewer different module types. Finally, ease of maintenance is improved by using fewer module types.

[0010] An advantageous further development of the proposed vehicle module CPM and / or the ground module GPM is characterized in that the assemblies BG n include at least two different ones from the following:

[0011] Assembly BG of a positioning system / position detection system, in particular a UWB positioning system, for determining a relative position of the vehicle module CPM to the ground module GPM,

[0012] Module BG of a living object detection (LOD) for detecting a living object underneath the vehicle and / or in an area between the vehicle module CPM and the ground module GPM, Module BG of a foreign object detection (FOD) in an area between the vehicle module CPM and the ground module GPM,

This results in, for example, the following further developments.

[0017] Note: The term "electronic" is understood broadly herein. The term is used synonymously with the term "electrical." The term "electronic components" encompasses all passive or active components used to generate, receive, conduct, process, and transmit electrical and / or electromagnetic and / or electro-optical signals.

[0018] The antenna modules AM are advantageous n=1 and AM n=2 designed in such a way that they use at least one electronic component, an electronic component group, in particular at least one (transmitting and / or receiving) antenna in common.

[0019] The analog circuit modules ASM are advantageous n=1 and ASM n=2 designed in such a way that they share at least one electronic component group.

[0020] The microprocessor modules MPM are advantageous n=1 and MPM n=2 designed in such a way that they use at least one electronic component, one electronic component group and / or in particular one processor in common.

[0021] The shared electronic component group is advantageous, for example, an analog or digital circuit, a resonant circuit, an amplifier, an attenuator, a logic circuit, or a filter. This list is not exhaustive. A particularly preferred development of the proposed vehicle module CPM and / or the ground module GPM is characterized in that the microprocessor modules MPM n=1 and MPM n=2 physically as a single microprocessor module MPM 1 2 are designed, wherein at least one or several or all electronic components of the microprocessor module MPM 1 2 from both assemblies BG n=i and BG n=2is / are used jointly. If several microprocessor modules MPM n present, two or more or all microprocessor modules MPM are preferred n as the only microprocessor module MPM 1 2 ... executed, wherein at least one or several or all electronic components of the single microprocessor module MPM 1 2 ... of the two, more or all assigned modules BG n be used.

[0022] A particularly preferred development of the proposed vehicle module CPM and / or the ground module GPM is characterized in that the analog circuit modules ASM n=1 and ASM n=2 physically as a single analog circuit module ASM 1 2 are designed, wherein at least one or several or all electronic components of the analog circuit module ASM 1 2 from both assemblies BG n=i and BG n=2is / are used together.

[0024] The MPM module(s) are advantageous 1 2 or MPM 1 2 ... and / or ASM 1 2 or ASM 1 2 ... and / or AM 1 2 or AM 1 2 ... each designed as a single, mechanically separately replaceable module. A second aspect of the invention relates to an inductive charging system for charging an energy storage device of a vehicle, comprising at least one vehicle module CPM and / or one floor module GPM, as described above.

[0031] The GPM floor module comprises the three electronic components:

[0032] - a position detection system / positioning system (POS): BG n =i, a live object detection (LOD) system: BG n=2 and a communication system for data transmission between the ground module GPM and the vehicle module CPM (COM): BG n=3 .

[0033] Further components of the floor module are not shown and are not relevant for the explanation of the present inventive idea.

[0034] Each of the three electronic assemblies mentioned above: BG n =i, BG n=2 , BG n=3 Each has a microprocessor module MPM n , an analog circuit module ASM n and an antenna module AM n on.

[0035] Fig. 1 shows a first embodiment of the invention of three assemblies BG n=1 , BG n=2 , BG n=3 a ground module GPM, comprising a position detection system / positioning system (POS): BG n=i, a live object detection (LOD) system: BG n=2 and a communication system for data transmission between the ground module GPM and the vehicle module CPM (COM): BG n=3 .

Furthermore, the analog circuit modules ASM n=1 and ASM n=2 identically constructed and configured, which is indicated in Fig. 1 by a larger frame. Finally, the antenna modules AM n=1 and AM n=2 identically constructed and set up, which is indicated in Fig. 1 by a highlighted dashed line of the assigned frames.

This reduces the number of modules required in the ground module from 9 to 8.

[0041] The microprocessor modules MPM n=1 , MPM n=2and MPM n=3 are designed differently in this embodiment. This reduces the number of modules required in the GPM floor module from 9 to 5.

[0042] Will the microprocessor modules MPM n=2 , MPM n=2 and MPM n=3 physically and mechanically as a single module MPM 1 2 ,3(POS / LOD / COM) designed in such a way that several or all electronic components of the microprocessor module MPM 1 2 3 from the assemblies BG n =i, BG n=2 , and BG n=3 are used jointly, then the required number of corresponding modules in the GPM can be reduced from 9 to 3.
