[0014] In particular, the power element is designed to deliver the DC power absorbed by the DC power source to a DC power consumer without converting or transforming the DC power, in particular without converting the DC power into AC power and back into DC power. Alternatively, only the level of the DC power can be converted using a conversion element, for example, from 48 V DC to 12 V DC.

[0015] This embodiment makes it possible to deliver DC power directly from a DC power source to a DC power consumer, in particular without conversion. This results in a provision of DC power that is possible without conversion losses. This provides a particularly efficient power supply device. In particular, the power element is designed to deliver the AC power absorbed by the AC power source to an AC power consumer without converting or transforming the AC power, in particular without converting the AC power into a DC voltage and back into an AC power. Alternatively, only the level of the AC power can be converted using a conversion element, for example from 230 V AC to 110 V AC.

[0016] This embodiment makes it possible to supply AC power directly from an AC power source to a DC power consumer, particularly without conversion. This results in the provision of AC power without conversion losses. This provides a particularly efficient power supply device.

[0017] According to one embodiment, the DC power is delivered and data is provided via a single interface of the power supply device.

[0018] In particular, this is an interface designed to provide both DC power and data, such as a USB port, a USB-C port, a Lightning port, or a network port operating under the Power over Ethernet or IEEE802.3 standard.

[0019] This embodiment makes it possible to supply a consumer with data and power, in particular DC power, simultaneously. This provides a particularly compact and low-cable power supply device. According to one embodiment, the power supply device comprises an information element configured to receive power source information and a control element configured to control the output power depending on the power source information.

[0020] Power source information is information regarding the power consumed by the power supply device, in particular by means of the power delivered by the DC power source and / or the AC power source. The information element can be configured to receive the power source information wirelessly and / or wired.

[0021] The power supply device also includes a control element configured to control the output power depending on the power source information. In particular, the control element is configured to control the output DC power and / or the output AC power depending on the power source information. For example, the control element can be configured to increase the output power, in particular to a maximum power, and / or to decrease it, in particular to a minimum power and / or to zero, depending on the received power source information.

[0022] This embodiment makes it possible to intelligently control the power output to the respective consumers. In particular, the power supply device according to the invention makes it possible to dynamically adapt the power output to the conditions of the power source. This provides a particularly flexible power supply device. According to one embodiment, the power source information includes building performance information.

[0023] Building performance information is information relating to the performance of the building in which the power supply device is used.

[0024] For example, the building performance information includes information relating to electrical power generators and / or energy storage devices present in the building or directly connected thereto, which are designed to output electrical power. A power generator is, for example, a photovoltaic system arranged on the roof of the building, a wind turbine arranged in the garden, a battery-electric vehicle connected to the building in the garage, and / or a battery and / or an accumulator arranged in the building. These power generators are designed to provide electrical power to the building and in particular to the power supply device. The building performance information can then include information on the availability of the power and / or the amount of power generated or available by the power generators.

[0025] This embodiment makes it possible to preferentially use power generators located on or in the building, particularly as soon as and / or as long as they can provide power. Thus, a particularly efficient power supply device is provided.

[0026] According to one embodiment, the power source information includes utility network information.

[0027] Supply network information is information relating to the electrical supply network provided by a supply network operator. In particular, such supply network information includes information regarding the power supplied to the power supply device via the supply line, for example, the availability of the power and / or the level of available power, in particular whether problems, fluctuations, or outages occur in the electrical supply network.

[0028] In particular, consumer performance information does not include building performance information and vice versa.

[0029] This embodiment makes it possible to respond dynamically to supply services provided by a utility grid operator. In particular, this embodiment allows for a flexible response to a power outage, and individual or multiple less important consumers can be excluded from the power supply, while other, more important consumers can continue to be supplied. Thus, a particularly secure, especially reliable, power supply device is provided.

[0030] According to one embodiment, the information element is further configured to receive consumer power information and the control element is further configured to control the output power depending on the consumer power information.

[0031] Consumer power information is information regarding the power delivered to the consumer by the power supply device, in particular a delivered DC power and / or a delivered AC power. The consumer power information can also be received wirelessly or wired by the information element. For example, the consumer power information can include information regarding the minimum and / or maximum power that the consumer can consume. This embodiment makes it possible to dynamically regulate the power delivered to a consumer. In particular, this embodiment can reduce a power output to a consumer, in particular to a minimum power, if the consumer power information indicates this. Thus, a particularly efficient power supply device is provided.

[0032] According to one embodiment, the information element is further configured to receive temperature information and the control element is further configured to control the output of the power depending on the temperature information.

[0033] Temperature information relates to a temperature of the power supply device, in particular a temperature in a housing of the power supply device. For this purpose, the information element can have access to a temperature sensor that is arranged in and / or on the housing of the power supply device and detects the temperature.

[0034] In particular, the control element can be designed to reduce the output power when a predetermined maximum temperature is exceeded and / or to increase the output power when the predetermined maximum temperature is undershot, in particular by applying a hysteresis.

[0035] According to one embodiment, the power element is further designed to detect an error in the power output to the at least one consumer.

[0036] An error that occurs during the power delivery to the at least one consumer is, for example, an overvoltage and / or an overcurrent during the power delivery. An overvoltage or an overcurrent is the delivery of a voltage or current that is too high for the respective consumer. Alternatively or additionally, such an error is the occurrence of a short circuit in the at least one consumer and / or an associated cable. Alternatively or additionally, the occurrence of such an error is incorrect polarity reversal, in particular incorrect polarity reversal of a DC power consumer.

[0037] Such an error can be detected by suitable sensors and / or circuits.

[0038] According to one embodiment, the power element is further configured to correct the detected error.

[0039] In particular, the power element is further designed to reduce, decrease and / or switch off the power output, in particular the output voltage and / or the output current, in the event of a detected overvoltage, overcurrent and / or short circuit.

[0040] Alternatively or additionally, the power element is particularly designed to reverse or switch the polarity reversal and / or to reduce and / or switch off the output power in the event of a detected incorrect polarity reversal.

[0041] This design allows the power to be delivered to the consumer(s) particularly safely. In particular, this design reduces the risk to users of the device.

[0042] According to one embodiment, the information element is further configured to receive segment information, and the control element is further configured to control the power output depending on the segment information. Segment information is information relating to different segments of one or more consumers, in particular one or more DC power consumers and one or more AC power consumers. For example, one or more DC power consumers can be combined into a first DC power segment, and one or more further DC power consumers can be combined into a second DC power segment.Alternatively or additionally, one or more AC power consumers may be combined to form a first AC power segment and one or more further AC power consumers may be combined to form a second AC power segment.

[0043] For example, consumers are grouped into a segment based on their typical power consumption. Consumers are grouped into a segment based on their power type, i.e., whether they consume DC or AC power. Consumers are also grouped into a segment based on their desired supply reliability.

[0044] One or more consumers can be assigned to a segment by a user, for example, at a connection on the power supply device, for example, using a button or a switch. Alternatively or additionally, one or more consumers can be assigned to a segment at a common user interface of the power supply device. For this purpose, additional power provision parameters can be defined or changed, such as the minimum output power, the duration of a supply security, etc. This embodiment makes it possible to reduce the power to one or more consumers grouped in a first segment while maintaining the power to one or more consumers grouped in another segment.For example, the first segment may include consumers that charge batteries that are not urgently needed, while the second segment may include consumers that provide critical and / or required infrastructure.

[0045] In particular, this makes it possible for certain consumers organized in a segment to only be supplied with power if sufficient DC power is available or generated by the DC power source.

[0046] In particular, the segment information for one or more consumers can also be stored temporarily or permanently in the power supply device. Whether and, if so, for how long the segment information is stored can be individually determined or configured by a user for each consumer.

[0047] This makes it possible for previously set segment information to be retrieved even when the consumer is reconnected to the power supply device without having to re-enter it.

[0048] The object mentioned above is also achieved by a power supply system, comprising an embodiment of a previously mentioned power supply device and one or more of the above-described AC power sources and / or one or more of the above-described DC power sources and / or one or more of the above-described data sources. The object mentioned above is also achieved by a power supply method, comprising the steps of receiving electrical DC power from a DC power source, delivering the received DC power to at least one first consumer, receiving electrical AC power from an AC power source, delivering the received AC power to at least one second consumer, receiving data from a data source, and providing the data to the at least one first consumer.

[0049] According to one embodiment, the power supply method further comprises the steps of receiving power source information and controlling the output power depending on the power source information.

[0050] The power supply method can in particular be carried out partially or completely by the previously described power supply device and / or the previously described power supply system.

[0051] The object mentioned at the outset is also achieved by a power supply network comprising a first power supply device according to one of the previously described embodiments and a second power supply device according to one of the previously described embodiments, wherein the power element of the second power supply device is designed to receive electrical DC voltage power from the first power supply device and to deliver it to at least one first consumer, and the power element of the second power supply device is further designed to receive electrical AC voltage power from the first power supply device and to deliver it to at least one second consumer, and wherein the data element of the second power supply device is designed to receive data from the first power supply device and to provide it to the at least one first consumer.

[0052] Thus, the second power supply device represents the first and second consumers for the first power supply device and / or the first power supply device represents the DC power source, the AC power source and the data source for the second power supply device.

[0053] It is understood that several, in particular any number of additional power supply devices according to one of the previously described embodiments can also be interconnected to form a power supply network.

[0054] Such a power supply network is free from cable length restrictions and can be interconnected in any topology.

[0089] The power element 110 is also designed to deliver DC power to the DC voltage source 20.

By means of these elements of the power supply device described above

[0090] 100, the following use cases are possible:

[0091] In an operating case in which power can be provided by the AC power source(s) 10, but no power can be provided by the DC power source(s) 20, for example due to the building performance information that there is no sun, no wind and / or the batteries / accumulators are empty, the power supply device 100 can receive power exclusively from the AC voltage source 10 and provide it to one or more consumers and in particular also convert the AC power into DC power and thus provide a DC power consumer 210.

[0092] This building performance information can be anticipated, in particular, by the power supply device 100, for example, because a current and / or future weather condition is taken into account and / or because a current and / or future charge level of batteries / accumulators is taken into account. As a result, as long as DC power can still be generated by a DC power source 20, it can be stored in batteries or accumulators and / or supplied to DC power consumers 210.

[0093] In an operating case in which power can be provided by the DC power source(s) 20, but no power can be provided by the AC power source(s) 10, for example, due to the supply network information that a supply network fault or failure is currently or in the future occurring, the power supply device 100 can receive power exclusively from the DC power source 20 and supply it to one or more consumers, in particular also convert the DC power into AC power, thus supplying it to an AC power consumer 220. In this case, supply by the DC power source 20 to the supply network can also be prevented.

[0094] This supply network information can be anticipated, in particular, by the power supply device 100, for example, because a future supply network state and / or a current time is taken into account. As a result, as long as AC power can still be generated by an AC power source 10, this power can be stored in batteries or accumulators and / or supplied to AC and / or DC power consumers 210. In particular, a specific time at which, for example, AC power from the AC power is more favorable can also be awaited.

[0095] In an operating case in which both power can be provided by the DC power source(s) 20 and power can be provided by the AC power source(s) 10, the power supply device 100 can receive DC power from the DC power source 20 and provide it to one or more DC voltage consumers 210, in particular without converting it beforehand, and can also receive AC power from the AC power source 10 and provide it to one or more AC voltage consumers 220, in particular without converting it beforehand.

[0096] Furthermore, in all cases, the power supply device 100 can anticipate a consumption of one or more consumers, in particular based on received consumer power information and / or a time of day, for example because a DC power consumer 210 comprises an accumulator and therefore a predetermined period of time can be waited before providing the power and / or because it is known that a certain AC power consumer permanently requires a constant and / or maximum power and / or because it is known that a certain consumer, such as a heat pump, requires a constant and / or maximum power at a certain time of day.

[0097] The power supply system 1000 includes, in addition to the power supply device 100 described above, one or more AC power sources 10 described above and / or one or more DC power sources 20 described above and / or one or more data sources 30 described above.

[0098] In particular, the power supply device 100 and one or more data sources 30 can be integrated into a single housing that can be plugged into a conventional household outlet. Alternatively, the power supply device 100 can be configured as a flush-mounted device. More specifically, the power supply device 100 can be referred to as a smart router, smart energy router, or smart power outlet.

[0099] Fig. 2 shows a schematic flow diagram of a power supply method 2000.

[0100] The power supply method 2000 begins with a first step 2010 in which DC power is received from a DC power source.

[0101] The power supply method 2000 continues with a further step 2020, in which the absorbed DC power is delivered to a first load, which is a DC power load. The power supply method 2000 continues with a further step 2030, in which AC power is absorbed from an AC power source.

[0102] The power supply method 2000 continues with a further step 2040 in which the absorbed AC power is delivered to a second load which is an AC power load.

[0103] The power supply method 2000 continues with a further step 2050 in which power information is received.

[0104] The power supply method 2000 continues with a further step 2060 in which the delivered power is controlled depending on the received power information.

[0105] The power supply method 2000 continues with a further step 2070 in which data is received from a data source.

[0106] The power supply method 2000 continues with a further step 2080 in which the data is provided to the first consumer.

[0107] It is understood that some or all of the steps may occur in a different order and / or simultaneously. In particular, steps 2010, 2020, 2030, and 2040 may occur simultaneously and / or continuously. Further, in particular, steps 2070 and 2080 may occur before steps 2050 and 2060 and / or continuously.

[0108] Fig. 3 shows a power supply network 3000. The power supply network 3000 comprises a first power supply device 100 and a second power supply device 100'. Both the first power supply device 100 and the second power supply device 100' are constructed essentially the same as the power supply device described in connection with Fig. 1, or both the first power supply device 100 and the second power supply device 100' essentially fulfill the same functions as the power supply device described in connection with Fig. 1.

[0109] In accordance with Fig. 1, the first power supply device 100 has a power element 110, an information element 120, a control element 130, a data element 140 and a conversion element 150, and the second power supply device 100' has a power element 110', information element 120', control element 130', data element 140' and conversion element 150' of the same or similar construction.

[0110] However, unlike the first power supply device 100, the second power supply device 100' is not connected to a DC power source 20, an AC power source 10 or a data source 30, but exclusively to the first power supply device 100, which fulfills these functions for the second power supply device 100' or provides them to them.

[0111] In other words, the power element 110' of the second power supply device 100' is designed to receive electrical DC voltage power from the power element 110 of the first power supply device 100 and to deliver it to at least one first consumer 210.

[0112] The power element 110' of the second power supply device 100' is further configured to receive electrical AC power from the power element 110 of the first power supply device 100 and to deliver it to at least one second consumer 220.

[0113] The data element 140' of the second power supply device 100' is configured to receive data from the data element 140 of the first power supply device 100 and to provide it to the at least one first consumer 210.

[0114] In other words, the second power supply device 100' represents both the first and second loads for the first power supply device 100 and receives AC power, DC power, and data therefrom and delivers them to the first load 210 and the second load 220.

[0115] For this purpose, the second power supply device 100' is connected to the first line supply line 100 via a first power supply line 111, an information line 112, a data line 113, and a second power supply line 114. The first power supply line 111 provides AC power, the information line 112 provides power information, the data line 113 provides data, and the second power supply line 114 provides DC power from the first power supply device 100 to the second power supply device 100'. This can be done, in particular, via a common physical cable, so that the first power supply device 100, the second power supply device 100', and possibly other similar or identical power supply devices are interconnected or connected to one another.

[0116] In particular, the AC power source 10, the DC power source 20 and / or the data source 30 can also be arranged and configured together such that they provide a common physical output to which the previously described cable can be connected in order to supply one or more power supply devices, in particular the first power supply device 100, with DC power, AC power, data and / or power information.

[0117] The second power supply device 100' can, in particular, perform the properties of a repeater, amplifier, or proxy. For technical reasons, direct current and data in particular cannot be transmitted even over medium distances without amplification, or amplification is beneficial. For this purpose, the power supply network 3000 can consist of any number of power supply devices, for example, three, four, eight, or 16, which together form the power supply network. As a result, there are no spatial limitations for the power supply devices or for the power supply systems 1000" described below, in particular not due to cable length limitations that actually exist, especially for data lines.

[0118] In particular, the multiple power supply devices can be arranged or interconnected in any topography. A bus or line topology is particularly suitable for this purpose. This enables easy retrofitting.

[0119] Furthermore, in particular, the first power supply device 100 is configured to provide a higher data bandwidth to the second power supply device 100' than to a consumer. Likewise, in particular, the first power supply device 100 is configured to provide the second power supply device 100' with the maximum possible data bandwidth. For this purpose, the first power supply device 100 or the first data element 140 can be configured to detect whether it is providing data to another, identical, or similar power supply device, or to a different consumer.

[0120] Furthermore, in particular, the first power supply device 100 is designed to provide the second power supply device 100' with higher power—both DC power and AC power—in particular power with a higher voltage and / or a higher current than that supplied to a consumer. Likewise, in particular, the first power supply device 100 is designed to provide the second power supply device 100' with the maximum possible power. For this purpose, the first power supply device 100 or the first power element 110 can be designed to detect whether it is providing data to another, identical or similar power supply device, or to a different consumer. In particular, the power supplied to a consumer can be below a so-called safety voltage, and that supplied to a further power supply device can be above this.

[0121] In addition, the first power supply device 100 can also be designed to supply, in addition to the second power supply device 100', further consumers not shown in Fig. 3 with DC power, AC power, data and / or power information via corresponding lines, also not shown.

[0122] Also shown in Fig. 3 is a power supply system 1000" which differs from Fig. 1 and which in the present case consists of at least two power supply devices 100, 100' and a data source 30 and / or a DC power source 20. List of reference symbols
