Description

[0001] The invention relates to a method for providing electrical energy for an electrical consumer by means of an electronic computing device according to independent patent claim 1. Furthermore, the invention relates to a computer program product, a computer-readable storage medium and an electronic computing device.

[0002] Battery-electric storage systems are already known from the state of the art and are used, for example, in households, for example in photovoltaic systems or wind turbines, as well as in motor vehicles, for example in at least partially electrically powered motor vehicles or fully electrically powered motor vehicles.

[0003] Furthermore, it is already known that, in the spirit of the energy transition, preferential use should be made of electrical energy from sustainable energy generation systems, such as photovoltaic systems or wind turbines. For example, certificates can be issued that certify to an electrical consumer, household, or industrial facility that a certain percentage of the electrical energy used comes from sustainable energy generation.

[0004] The problem here is that, for example, in the energy storage device which has been charged with electrical energy, it is not possible to determine whether the energy storage device was generated or stored using sustainable energy or, for example, using so-called brown energy, for example based on electricity generation using coal.

[0005] DE 10 2020 205 261 B4 relates to a method for recording electrical consumption and generation, wherein a power flow is recorded bidirectionally and with precise time at an electrical energy storage device by means of a power flow sensor, wherein at least one quality characteristic of a respective power flow is determined or obtained with precise time, wherein energy quantities stored in the electrical energy storage device are determined on the basis of a respective power flow, wherein the respective corresponding quality characteristic is or is assigned to the respective determined energy quantity, and wherein the respective assigned quality characteristics are provided.

[0006] The object of the present invention is to provide a method, a computer program product, a computer-readable storage medium and an electronic computing device by means of which electrical energy can advantageously be provided to the electrical consumer.

[0007] This object is achieved by a method, a computer program product, a computer-readable storage medium, and an electronic computing device according to the independent patent claims. Advantageous embodiments are specified in the subclaims.

[0008] One aspect of the invention relates to a method for providing electrical energy to an electrical consumer using an electronic computing device. A type of generation of the electrical energy is detected in a first electrical energy storage device using the electronic computing device. A type of generation of electrical energy is detected in a second electrical energy storage device separate from the first electrical energy storage device using the electronic computing device. Electrical energy is provided to the electrical consumer depending on the detected type of generation by the first electrical energy storage device or the second electrical energy storage device using the electronic computing device.

[0009] In particular, it can be provided that, for example, information regarding the type of generation is stored in the first electrical energy storage device. In particular, the information regarding the electrical energy is stored with the type of generation. For example, it can be stored that the electrical energy storage device is charged with 50 percent electrical energy from sustainable energy generation. The other 50 percent can be stored, for example, from so-called brown energy. The same method is provided, for example, for the second electrical energy storage device.It can then be decided, for example, that the electrical energy consumer should only be supplied with sustainably generated energy, that only 50 percent of the electrical energy is provided from the first energy storage device, and then, for example, the system switches over to the second energy storage device, which in turn provides the percentage of electrical energy that was also generated using sustainable energy.

[0010] In particular, this makes it possible to ensure that the electrical consumer is operated exclusively with electrical energy generated through sustainable energy production. For example, appropriate documentation can then be maintained detailing how the electrical consumer is operated, and the documentation can state, for example, that over a certain period of time, for example, over a year, the electrical energy consumer was supplied with 90 percent sustainable energy. This can be used, for example, for subsequent procedures, such as sustainability certifications or certifications for compliance with climate targets.

[0011] In particular, a switching process is thus provided which makes it possible to switch between at least two electrical energy storage devices (at this point it should be mentioned that more than two electrical energy storage devices can also be provided), whereby the aim here is to always only provide as much electrical energy from the electrical energy storage devices as has been sustainably generated.

[0012] For example, the electrical consumer may be a household or an industrial facility. The household may, for example, have a permanently installed electrical energy storage device. For example, the electrical energy storage device may be coupled to a photovoltaic system, allowing sustainable electrical energy from the photovoltaic system to be fed into the electrical energy storage device. A mobile electrical energy storage device, such as a motor vehicle with an electrical energy storage device, may be provided as a second electrical energy storage device. If the motor vehicle is coupled to the household, the electrical energy storage device of the motor vehicle can be charged and discharged bidirectionally.If, for example, the household's electrical energy storage device is discharged to the extent that it was sustainably charged, the electrical energy storage device of the vehicle can now be used, which was also sustainably charged, for example.

[0013] In particular, it can be provided, for example, that the motor vehicle was also charged with sustainable electrical energy at another location, for example, at a workplace. Thus, the motor vehicle "brings" sustainable electrical energy from the workplace to the household. Information about how much sustainable electrical energy was fed into the workplace is also stored, for example, in the motor vehicle's battery management system. After the motor vehicle is connected to the household grid, the electrical energy of the motor vehicle, in particular the sustainably generated electrical energy of the motor vehicle, can now be used to supply the household with sustainable electrical energy.

[0014] The electronic computing device can be located in a motor vehicle, a house or even as a cloud server.

[0015] According to an advantageous embodiment, electrical energy generated by sustainable electrical energy generation is preferably provided to the electrical consumer. Sustainable electrical energy can, for example, be classified as electrical energy from a photovoltaic system, a wind turbine or the like. In particular, the sustainable energy is therefore green energy. In particular, it is then provided that electrical energy that has been generated sustainably is preferably provided to the electrical consumer. It can also be provided, for example, that if the sustainably generated electrical energy is used up from both the first energy storage device and the second energy storage device, no more electrical energy is then provided to the electrical consumer.Alternatively, after the sustainable energy has been consumed, it is of course also possible to use the public power grid.

[0016] It is also advantageous if, when the sustainably generated electrical energy in the first electrical energy storage device is consumed, sustainably generated energy from the second electrical energy storage device is provided to the electrical consumer. This ensures that only sustainably generated energy is provided to the electrical consumer, allowing the electrical consumer to be operated sustainably. It should be noted at this point that both energy storage devices can have different capacities.

[0017] A further advantageous embodiment provides that the respective type of electrical energy generation is provided in a respective battery management system of the respective electrical energy storage device. For example, the battery management system of the respective electrical energy storage device can have a storage device for this purpose. The information can then be stored that, for example, 52 percent of the capacity of the electrical energy storage device was generated sustainably. Based on this information, it can be realized, for example, that the electronic computing device retrieves this information and thus draws only 52 percent of the electrical energy from the energy storage device. This allows the electrical energy consumer to be reliably operated with sustainable energy.

[0018] In a further advantageous embodiment, at least a respective percentage of the respective generation type is provided depending on the respective total capacity of a respective energy storage device. This makes it possible to store the generation type according to the total capacity, thus easily supplying the electrical consumer with sustainable energy.

[0019] It is also advantageous if the energy supply, particularly with regard to the type of generation, is documented by the electrical consumer using the electronic computing device. For example, corresponding digital certificates can be issued for a specified period of time, such as days, weeks, months, or years. These certificates can then be presented to the relevant authorities, for example, to demonstrate the extent to which the respective electrical consumer has been operated in a climate-friendly manner.

[0020] It is also advantageous if at least one of the two electrical energy storage devices is provided as a mobile electrical energy storage device. In particular, one of the two electrical energy storage devices can be designed as an electrical energy storage device of an at least partially electrically powered motor vehicle or a fully electrically powered motor vehicle. It can thus be provided that the mobile electrical energy storage device is charged with sustainable energy at another location, which can then be supplied to the electrical consumer. This can increase the capacity of the sustainably generated energy for the consumer.

[0021] Furthermore, it has proven advantageous to provide electrical energy for a household electrical network as an electrical consumer. Alternatively or additionally, electrical energy can be provided for an industrial plant. This makes the process highly flexible for use at different consumption locations.

[0022] The method presented is, in particular, a computer-implemented method. Therefore, a further aspect of the invention relates to a computer program product with program code means that, when the program code means are processed by the electronic computing device, cause an electronic computing device to perform a method according to the preceding aspect.

[0023] The invention therefore also relates to a computer-readable storage medium with the computer program product.

[0024] Furthermore, the invention also relates to an electronic computing device for providing electrical energy to an electrical consumer, wherein the electronic computing device is designed to carry out a method according to the preceding aspect. In particular, the method is carried out by means of the electronic computing device.

[0025] Advantageous embodiments of the method are to be regarded as advantageous embodiments of the computer program product, the computer-readable storage medium, and the electronic computing device. The electronic computing device has material features for this purpose in order to be able to carry out corresponding method steps.

[0026] A computing unit / electronic computing device can be understood, in particular, as a data processing device that contains a processing circuit. The computing unit can therefore, in particular, process data to perform computing operations. This may also include operations for performing indexed access to a data structure, for example, a look-up table (LUT).

[0027] The computing unit may, in particular, contain one or more computers, one or more microcontrollers, and / or one or more integrated circuits, for example one or more application-specific integrated circuits (ASICs), one or more field-programmable gate arrays (FPGAs), and / or one or more single-chip systems (SoCs). The computing unit may also contain one or more processors, for example one or more microprocessors, one or more central processing units (CPUs), one or more graphics processing units (GPUs), and / or one or more signal processors, in particular one or more digital signal processors (DSPs). The computing unit may also include a physical or virtual network of computers or other of the aforementioned units.

[0028] In various embodiments, the computing unit includes one or more hardware and / or software interfaces and / or one or more memory units.

[0029] A memory unit can be a volatile data memory, for example a dynamic random access memory (DRAM) or a static random access memory (SRAM), or a non-volatile data memory, for example a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a flash memory or flash EEPROM, a ferroelectric random access memory (FRAM), a magnetoresistive random access memory,MRAM (magnetoresistive random access memory) or phase-change random access memory (PCRAM).

[0030] Further features of the invention emerge from the claims, the figure, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figure, can be used not only in the respective specified combination, but also in other combinations or on their own.

[0031] The invention will now be explained in more detail using a preferred embodiment and with reference to the drawings.

[0032] The single figure shows a schematic block diagram according to an embodiment of an electronic computing device for carrying out an embodiment of the method according to the invention.

[0033] In the figure, identical or functionally identical elements are provided with the same reference numerals.

[0034] Fig. 1 shows a schematic block diagram according to one embodiment of an electronic computing device 10 for an electrical load 12. In the present exemplary embodiment, the load 12 is shown in a household 14. The household 14 has at least one photovoltaic system 16, which can generate electrical energy from solar radiation. The household 14 further has at least one first electrical energy storage device 18, which is coupled to the photovoltaic system 16. The first electrical energy storage device 18 is further coupled to the electrical load 12.

[0035] Furthermore, the Fig. 1 a public power grid 20. The public power grid 20 can be coupled both to the first electrical energy storage device 18 and to the electrical consumer 12. The public power grid 20 can be supplied with electricity, for example, via a further photovoltaic system 22. In particular, the electricity from the further photovoltaic system 20 is so-called sustainable electricity, in particular so-called sustainable energy. Furthermore, a power plant 24 is shown, which can also provide electrical energy for the public power grid 20. The power plant 24 can, for example, be a lignite-fired power plant, which in particular does not serve as a sustainable energy source. The further photovoltaic system 22 can also be provided by an industrial plant, here referred to in particular as employer 26.

[0036] Furthermore, a motor vehicle 28 is shown. The motor vehicle 28 is designed as an at least partially electrically operated motor vehicle 28 or as a fully electrically operated motor vehicle 28. In this case, the motor vehicle 28 has a second electrical energy storage device 30. In particular, the second electrical energy storage device 30 is thus essentially designed as a mobile energy storage device. The motor vehicle 28 can also be supplied with electrical energy via the electrical consumer 12, for example via a corresponding wall box that enables bidirectional charging. Furthermore, the electrical energy storage device 30 can also be fed with electrical energy from the photovoltaic system 16. The motor vehicle 28 can, for example, also drive to the employer 26.It is also possible that, for example, sustainable electrical energy generated by the further photovoltaic system 22 at the workplace 26 is absorbed by the motor vehicle 28, in particular by the second electrical energy storage device 30.

[0037] In particular, a method can thus be provided which provides electrical energy to the electrical consumer 12. In this case, in particular, a detection type of the electrical energy in the first electrical energy storage device 18 is detected by the electronic computing device 10. A generation type of the electrical energy in a second electrical energy storage device 30, which is separate from the first electrical energy storage device 18, can also be detected by the electronic computing device 10. The electrical energy is then provided to the electrical consumer 12 depending on the detected generation type by the first electrical energy storage device 18 or the second electrical energy storage device 30 by the electronic computing device 10.

[0038] In particular, it is provided that electrical energy generated by sustainable electrical energy generation is preferably provided to the electrical consumer 12. For example, when the sustainably generated electrical energy is consumed in the first electrical energy storage device 18, sustainably generated energy from the second electrical energy storage device 30 can be provided to the electrical consumer 12.
