[0004] The object of the present invention is to provide an improved power supply device, an improved power supply method and an improved power supply system.

[0005] This object is achieved by a power supply device comprising a power element configured to receive electrical power from a power source and to deliver it to at least one consumer, an information element configured to receive power source information, and a control element configured to control the delivered power depending on the power source information.

[0006] When reference is made below to power, in particular electrical power, this includes both an electrical current and an electrical voltage, which together result in the power. For example, the power supply device can be designed to receive and / or deliver a constant voltage and a variable current. Likewise, the power supply device can be designed to receive and / or deliver a constant current and a variable voltage. The power supply device can also be designed to receive and / or deliver a constant current and a constant voltage.

[0007] The power supply device initially comprises a power element configured to receive electrical power from a power source. A power source is a source that supplies electrical power to the location of the power supply device, such as an electrical line. In particular, the power source is a line of a utility grid operator that is connected to a building in which the power supply device is located and supplies electrical power thereto. In other words, the power supply line can have a connection, in particular a direct connection, to an electrical supply grid.

[0008] The power element is also designed to deliver the absorbed power to one or more loads electrically connected to the power supply device. A load, in this case, is an electrical and / or electronic device that requires electrical power to perform its functions. The electronic power can be used, in particular, to enable the operation of the load and / or to charge a battery of the load.

[0009] The power supply device also includes an information element configured to receive power source information. Power source information is information regarding the power consumed by the power supply device, in particular by means of the power output by the power source. The information element can be configured to receive the power source information wirelessly and / or wired. Information is used herein in the generic plural and can also comprise a single piece of information. The power supply device also includes a control element configured to control the output power depending on the power source information.For example, the control element can be designed to increase the output power depending on the received power source information, in particular to a maximum power, and / or to decrease it, in particular to a minimum power and / or to zero.

[0010] The power supply device according to the invention makes it possible to intelligently control the power output to one or more 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.

[0011] According to one embodiment, the power source information includes building power information.

[0012] Building performance information is information relating to the performance of the building in which the power supply device is used.

[0013] 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.

[0014] 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.

[0015] According to one embodiment, the power source information includes utility network information.

[0016] 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.

[0017] In particular, consumer performance information does not include building performance information and vice versa.

[0018] 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.

[0019] 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.

[0020] Consumer power information is information regarding the power delivered to the consumer by the power supply device. 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.

[0021] This embodiment makes it possible to dynamically regulate the power delivered to a load. In particular, this embodiment allows the power delivered to a load to be reduced, in particular to a minimum power, if the load power information indicates this. Thus, a particularly efficient power supply device is provided.

[0022] According to one embodiment, the power supply device further comprises a data element configured to receive data from a data source and provide this data to the consumer. In particular, the data element is also configured to receive data from the consumer and / or provide data to the data source.

[0023] The data that the data element receives and / or provides is different from the information that the information element receives. In particular, the data is a data stream, such as internet access or access to a server.

[0024] The data source can be a router, a switch, and / or a hub and / or include access to a data network. The data can be received and / or provided both wired and wirelessly. For this purpose, the data element of the power supply device has, in particular, access to a data network, such as a LAN or WLAN. The data element itself can also act as a router, hub, or switch.

[0025] This embodiment makes it possible to provide not only power but also data to one or more consumers simultaneously. Thus, a particularly communicative power supply device is provided.

[0026] According to one embodiment, the power element is configured to receive DC power from a DC power source.

[0027] In particular, the power element is designed to receive a DC voltage power from a DC voltage power source located on or in the same building as the power supply device, for example one or more of the aforementioned building power sources or generators.

[0028] According to one embodiment, the power element is designed to deliver DC power to the at least one consumer.

[0029] In particular, the power element is designed to deliver the DC power absorbed by the DC power source to a DC power consumer, furthermore, in particular, 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.

[0030] 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 DC power being provided without conversion losses. This provides a particularly efficient power supply device.

[0031] According to one embodiment, the power element is designed to receive AC power from an AC power source

[0032] In particular, the power element is configured to receive AC power from an AC power source connected to the same building in which the power supply device is located, for example, one or more of the aforementioned utility grid power sources or generators.

[0033] According to one embodiment, the power element is designed to deliver AC power to the at least one consumer.

[0034] In particular, the power element is designed to deliver the AC power absorbed by the AC power source to an AC power consumer, furthermore, in particular, 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] In particular, the control element can be configured to reduce the output power when a predetermined maximum temperature is exceeded and / or to increase the output power when the temperature falls below the predetermined maximum, in particular by applying hysteresis. According to one embodiment, the power element is further configured to detect an error in the power output to the at least one consumer.

[0039] 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.

[0040] Such an error can be detected by suitable sensors and / or circuits.

[0041] According to one embodiment, the power element is further configured to correct the detected error.

[0042] 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.

[0043] Alternatively or additionally, the power element is particularly designed to reverse or switch the polarity in the event of a detected incorrect polarity reversal and / or to reduce and / or shut down the output power. These embodiments allow the power to be delivered to the load(s) particularly safely. In particular, this embodiment reduces the risk to users of the device.

[0044] According to one embodiment, the information element is further configured to receive segment information and the control element is further configured to control the output of the power depending on the segment information.

[0045] 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 additional DC power consumers can be combined into a second DC power segment. Alternatively or additionally, one or more AC power consumers can be combined into a first AC power segment, and one or more additional AC power consumers can be combined into a second AC power segment.

[0046] 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.

[0047] 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 switch. Alternatively or additionally, one or more consumers can be assigned to a segment via a common user interface of the power supply device. For this purpose, additional power supply parameters can be defined or changed, such as the minimum output power, the duration of a supply security period, etc.

[0048] This embodiment makes it possible to reduce the power to one or more consumers grouped together in a first segment while maintaining the power to one or more consumers grouped together 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.

[0049] 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.

[0050] 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.

[0051] This makes it possible for previously set segment information to be retrieved even when the consumer reconnects to the power supply device, without having to re-enter it. According to one embodiment, the power supply device further comprises a notification element configured to inform a user of a power source status.

[0052] A power source status is information about which of the previously described power sources is currently being used. In particular, a power source status is information about whether, or that, power is being drawn from or supplied at least partially, predominantly, or exclusively by electrical power generators and / or energy storage devices located in the building or directly connected to it. This information can be determined, for example, by the information element from the building performance information.

[0053] Furthermore, a power source status is, in particular, information about whether or not power is at least partially, predominantly, or exclusively drawn from or supplied by a supply network power source or a supply network power generator. This information can be determined, for example, by the information element from the supply network information.

[0054] Likewise, in particular, a power source status is information that the power drawn from or supplied by a supply grid power source or a supply grid power generator is power that was generated at least partially, predominantly, or exclusively, or not at all, from renewable energies. This information can, for example, also be determined by the information element from the supply grid information. Furthermore, in particular, a power source status is information that the power, in particular the DC power, is power at full, reduced, throttled, or minimal level.

[0055] The notification element is designed to output the information regarding the power source status, particularly during the delivery of power to one or more consumers. In particular, the notification element is designed to display or indicate the information regarding the power source status prior to delivery, particularly prior to the connection of one or more consumers to the power supply device. In particular, the notification element can be designed to permanently display a power source status on the power supply device, regardless of whether one or more consumers are connected to it and / or whether power is currently being delivered.

[0056] The notification element may, in particular, comprise a graphical and / or visual information display. For example, the notification element may be configured as one or more LEDs, in particular one or more multicolored or differently colored LEDs, which can inform a user about the power source status.

[0057] For example, an LED may glow red if no power is currently being delivered and / or cannot be delivered, for example because not enough power is being received.

[0058] Furthermore, for example, the or another LED may illuminate yellow if a restricted and / or reduced power output is currently occurring and / or may occur. Alternatively or additionally, the or another LED may illuminate yellow if a power output is generated at least partially, predominantly, or exclusively from power drawn from a utility grid power source or a utility grid power generator, in particular such power that was at least partially, predominantly, or exclusively not generated from renewable energy sources.

[0059] Furthermore, for example, the or another LED can light up green if a power output is currently taking place and / or can take place in full. Alternatively or additionally, the or another LED can light up green if a power output occurs at least partially, predominantly or exclusively from power that is drawn from electrical power generators and / or energy storage devices present in the building or directly connected thereto. Alternatively or additionally, the or another LED can light up green if a power output occurs at least partially, predominantly or exclusively from power that was obtained or provided at least partially, predominantly or exclusively from renewable energies by a supply grid power source or a supply grid power generator.

[0060] Alternatively or additionally, a power source status can also be displayed on a graphical display, such as an LCD. In addition to the information described above regarding the one or more LEDs, further information regarding the power source status can also be displayed, such as the current composition of the power sources from which power is received and delivered, and / or the amount of delivered power, for example, as a bar or pie chart or as a percentage. This information can also be determined based on the power source information.

[0061] This embodiment enables a user to quickly and easily determine the current and, in particular, future power source status and thus to make a decision as to whether and which devices he wants to connect and / or leave connected to the power supply device as a consumer.

[0062] According to one embodiment, the power supply device further comprises an input element configured to receive a user input, wherein the control element is further configured to control the output of the power depending on the user input.

[0063] The input element is a user interface that allows the user to direct a user input to the power supply device. The input element can be configured, for example, as a button, pushbutton, or switch. In particular, the input element can be connected to the notification element or integrated therein, for example, as an operable LED or as a touch display or screen. The input element can also be configured to receive segment information.

[0064] For example, the user can actuate the input element and thereby indicate that he wishes that the one or more consumers connected to the power supply device should only be supplied with power that is drawn from electrical power generators and / or energy storage devices present in the building or directly connected thereto and / or that only be supplied with power if power can be provided by electrical power generators and / or energy storage devices present in the building or directly connected thereto.

[0065] These may, in particular, be consumers with low power requirements that can and / or should be provided exclusively by electrical power generators and / or energy storage devices located in or directly connected to the building. In particular, these may be consumers that require or process DC power and / or that themselves include an energy storage device, so that power can also be provided at a later time.

[0066] Furthermore, for example, the user can actuate the input element and thereby indicate that he wishes that power should be supplied to the one or more consumers connected to the power supply device exclusively if a power supply can be made at least partially, predominantly or exclusively from a power that was obtained or provided at least partially, predominantly or exclusively from renewable energies by a supply network power source or a supply network power generator.

[0067] Here, too, these may be consumers that themselves include an energy storage device, so that power can also be provided at a later time.

[0068] Likewise, for example, the user may actuate the input element and thereby indicate that he wishes that power should be supplied to the one or more consumers connected to the power supply device only when power is available and / or can be provided by a utility grid power source or a utility grid power generator.

[0069] This may, in particular, involve consumers with high power requirements that cannot and / or should not be provided, or not exclusively, by electrical power generators and / or energy storage devices present in the building or directly connected to it. Furthermore, for example, the user can actuate the input element and thereby indicate that they wish that power should always be supplied to the one or more consumers connected to the power supply device, in particular regardless of the source.

[0070] These can particularly be critical consumers that require continuous power.

[0071] For example, the user can also actuate the input element and thereby indicate that he wishes a certain power level, in particular a minimum and / or maximum power and / or a predetermined and / or user-defined power, to be delivered to the one or more consumers connected to the power supply device.

[0072] The control element can then implement these user requests and thus control the power output to one or more consumers.

[0073] This design makes it possible to take user preferences into account and thus control the power output particularly dynamically.

[0074] The object mentioned at the outset 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.

[0075] The object mentioned at the outset is also achieved by a power supply method comprising the steps of receiving electrical power from a power source, delivering the received power to a consumer, receiving power source information and controlling the delivered power depending on the power source information.

[0076] According to one embodiment, the power supply method further comprises the steps of receiving data from a data source and providing the data to the consumer.

[0077] 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.

Likewise, the information element 120 is configured to receive utility network information and / or building performance information from the data element 30 and / or to provide it to the data element, in particular via the information line 32.

[0104] The power supply device 100 also includes a conversion element 150 configured to convert received power and then deliver the converted power to a consumer.

[0105] In particular, the conversion element 150 is configured to convert the AC power provided by the AC power source 10 in terms of the magnitude, frequency, and / or type of power. For example, the conversion element 150 is configured to convert the AC power provided by the AC power source 10 from 230 V to 110 V. Again, for example, the conversion element 150 is configured to convert the AC power provided by the AC power source 10 from 50 Hz to 60 Hz. Also, for example, the conversion element 150 is configured to convert the AC power provided by the AC power source 10 into a DC power.

[0106] Again, in particular, the conversion element 150 is configured to convert the level and / or type of DC power provided by the DC power source 20. For example, the conversion element 150 is configured to convert the DC power provided by the DC power source 20 with a DC power voltage of 48 V to 12 V. Again, for example, the conversion element 150 is configured to convert the DC power provided by the DC power source 20 into an AC power.

[0107] The power element 110 is also configured to deliver AC power to the AC voltage source 10. In particular, the power element 110 is configured to provide the AC power to the supply network via the power supply line 11 by previously generating or storing power from the DC voltage sources 20 or generators, in particular using the conversion element 150.

[0108] The power element 110 is also configured to supply DC power to the DC voltage source 20. In particular, the power element 110 is configured to provide the AC power supplied by the AC voltage sources, in particular using the conversion element 150, as DC power to a battery or accumulator via the power supply line 21.

[0109] The above-described elements of the power supply device 100 make the following applications possible in particular:

[0110] 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.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.

[0111] 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.

[0112] 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, it 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.

[0113] 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.

[0114] 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.

[0115] 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. 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 socket. Alternatively, the power supply device 100 can be configured as a flush-mounted device. More particularly, the power supply device 100 can be referred to as a smart router, smart energy router, or smart power outlet.

[0116] Fig. 2 shows a schematic flow diagram of a power supply method 2000.

[0117] The power supply method 2000 begins with a first step 2010 in which DC power is received from a DC power source.

[0118] 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.

[0119] The power supply method 2000 continues with a further step 2030 in which AC power is received from an AC power source.

[0120] 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.

[0121] The power supply method 2000 continues with a further step 2050, in which power information is received. The power supply method 2000 continues with a further step 2060, in which the output power is controlled depending on the received power information. The power supply method 2000 continues with a further step 2070, in which data is received from a data source.

[0122] The power supply method 2000 continues with a further step 2080 in which the data is provided to the first consumer.

[0123] 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.
