Abstract
Description
[Technical Field]
[0001] The present invention relates to a car pad module (CPM) and / or ground pad module (GPM) for an inductive charging system for charging a vehicle, particularly an electric vehicle or hybrid vehicle, wherein energy can be inductively transferred from the ground pad module GPM to the car pad module CPM. Furthermore, the present invention relates to an inductive charging system for a vehicle for charging a vehicle's energy storage device, comprising at least one such car pad module CPM and one such ground pad module GPM. [Background technology]
[0002] Prior art has shown various inductive vehicle charging systems consisting of at least one vehicle module CPM and one ground module GPM, and these will be discussed here. [Overview of the project] [Problems that the invention aims to solve]
[0003] The object of the present invention is to provide a vehicle module CPM and / or ground module GPM for an inductive charging system for charging a vehicle's energy storage device, which have low manufacturing costs, low failure rates, and are easy to maintain.
[0004] The present invention arises from the features of the independent claims. Advantageous improvements and embodiments are the subject matter of the dependent claims. Other features, possible uses, and advantages of the present invention will become apparent from the following description and consideration of exemplary embodiments of the invention depicted in the figures. [Means for solving the problem]
[0005] A first aspect of the present invention relates to a vehicle module CPM and / or a ground module GPM for an inductive charging system for charging a power storage device of a vehicle, and energy from the ground module GPM can be inductively transmitted to the vehicle module CPM. The vehicle module CPM and / or the ground module GPM have a number N of electronic assemblies BG n where n = 1, 2,..., N, and N ≥ 2, and each electronic assembly BG n comprises a microprocessor module MPM n , an analog switching circuit module ASM n , and an antenna module AM n .
[0006] The vehicle module CPM and / or the ground module GPM have at least two of the assemblies BG n such that the assemblies BG n=1 and BG n=2 have microprocessor modules MPM n=1 and MPM n=2 of the same structure and configuration, and / or analog switching circuit modules ASM n=1 and ASM n=2 of the same structure and configuration, and / or antenna modules AM n=1 and AM n=2 .
[0007] In this case, the term "modules of the same structure and configuration" is understood to mean, in particular, that these modules are electronically and mechanically configured so as to be usable in both one assembly BG n=1 and the other assembly BG n=2 , i.e., are interchangeable with each other. Thus, all requirements, functions, tasks assigned to both the assembly BG n=1 and the assembly BG n=2 are satisfied. The term also includes the meaning of "physically identical structure". This means that the modules affected are copies of each other.
[0008] On the one hand, these identical modules in structure and configuration reduce the number of module types, thus significantly lowering the manufacturing costs of the vehicle module CPM and / or ground module GPM. At the same time, fewer module types make the module less susceptible to errors. Ultimately, fewer module types improve maintainability.
[0009] A favorable further development of the proposed vehicle module CPM and / or ground module GPM is the assembly BG n However, it is characterized by being composed of at least two different elements: - A positioning / position detection system, particularly an assembly BG of a UWB positioning system, for determining the relative position of the vehicle module CPM to the ground module GPM. - Assembly BG of a Living Object Detection (LOD) for detecting living organisms in the area below the vehicle and / or between the vehicle module CPM and the ground module GPM. - Assembly BG for Foreign Object Detection (FOD) in the region between the vehicle module CPM and the ground module GPM. -Assembly BG of the communication system for communication between the vehicle module CPM and the ground module GPM. -Assembly BG of a communication system for communication between vehicle module CPM and / or ground module GPM or infrastructure communication interface.
[0010] Microprocessor Module MPM n=1 and MPM n=2 , and / or Analog Switching Circuit Module ASM n=1 and ASM n=2 , and / or antenna module AM n=1 and AM n=2These components are advantageously implemented as physically separate modules. The advantage of these modules is that they are mechanically easily interchangeable.
[0011] Alternatively, the microprocessor module MPM n=1 and MPM n=2 , and / or Analog Switching Circuit Module ASM n=1 and ASM n=2 , and / or antenna module AM n=1 and AM n=2 Because the modules are designed to partially share electronic components / component groups, only one of these components / component groups is needed for every two modules. This results in further advancements such as the following:
[0012] Note: The term “electronic” is used here with a broad understanding. This term is used synonymously with the term “electrical.” The term “electronic component” consists of all passive or active components used to generate, receive, conduct, process, and transmit electrical and / or electromagnetic and / or electro-optical signals. In this case, the group of components consists of multiple electronic components.
[0013] To have an advantage, the antenna module AM n=1 and AM n=2 It is designed to share at least one electronic component, one group of electronic components, and in particular at least one (transmitting and / or receiving) antenna.
[0014] Advantages include the analog switching circuit module ASM n=1 and ASM n=2 They are designed to share at least one group of electronic components.
[0015] Advantages include the microprocessor module MPM n=1 and MPM n=2It is designed to share at least one electronic component, one group of electronic components, and / or in particular one processor.
[0016] Using a common set of electronic components, such as analog or digital circuits, resonant circuits, amplifiers, attenuators, logic circuits, or filters, is advantageous. However, this list is not exhaustive.
[0017] A particularly preferred improvement to the proposed vehicle module CPM and / or grounding module GPM is the microprocessor module MPM. n=1 and MPM n=2 Physically a single microprocessor module MPM 1、2 Designed as a microprocessor module MPM 1、2 At least one or all of the electronic components in both assembly BG n=1 and BG n=2 Characterized by being shared by multiple microprocessor modules (MPMs). n If present, two or more or all microprocessor modules MPM n Preferably, a single microprocessor module (MPM) 1、2 ...designed as a single microprocessor module MPM 1、2 ...at least one or all of the electronic components of two or more or all of the associated assembly BG n It is used by [someone / something].
[0018] A particularly preferred improvement to the proposed vehicle module CPM and / or grounding module GPM is the analog switching circuit module ASM. n=1 and ASM n=2 ASM is a physically single analog switching circuit module. 1、2 Designed as an analog switching circuit module (ASM) 1、2 At least one or all of the electronic components in both assembly BG n=1 and BG n=2Characterized by being shared by multiple analog switching circuit modules (ASM). n If present, two or more or all analog switching circuit modules ASM n Preferably, a single analog switching circuit module (ASM) 1、2 ...designed as a single analog switching circuit module ASM 1、2 ...at least one or all of the electronic components of two or all of the associated assembly BG n It is used by [someone / something].
[0019] A particularly preferred improvement to the proposed vehicle module CPM and / or ground module GPM is the antenna module AM n=1 and AM n=2 But physically a single antenna module AM 1、2 Designed as an AM antenna module. 1、2 At least one or all of the electronic components in both assembly BG n=1 and BG n=2 It is characterized by being shared by multiple antenna modules AM n If present, two or more or all antenna modules AM n Preferably a single antenna module ASM 1、2 ...designed as a single antenna module ASM 1、2 ...at least one or all of the electronic components of two or all of the associated assembly BG n It is used by [someone / something].
[0020] To have an advantage, Module MPM 1、2 or MPM 1、2 ...and / or ASM 1、2 or ASM 1、2 ...and / or AM 1、2 or AM 1、2 ...are each designed as a single, mechanically separate, and interchangeable module.
[0021] Furthermore, the present invention relates to an inductive charging system for charging a vehicle's energy storage device, comprising at least one vehicle module CPM and / or ground module GPM as described above.
