Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household power distribution, in particular to a household power distribution device and a household power supply network. BACKGROUND

[0002] At present, there are more and more portable energy storage power suppliers in the market, and the product power is getting larger and larger. Purely used for outdoor power supply function may lead to too low use frequency and high cost, which is not cost-effective.

[0003] In addition, if the portable energy storage power is used for household power or emergency power, since the conventional portable energy storage power only has off-grid output function, if directly connected to the household power grid, the AC power of the two will damage household appliances due to phase difference problems when the commercial power and the portable energy storage power are output at the same time. The conventional method is to additionally match and install a corresponding slave distribution box for the portable energy storage power, that is, the household power grid is simultaneously configured with a main distribution box and a slave distribution box. The main distribution box is connected to the commercial power to supply power to non-critical loads of the household. The slave distribution box can be connected to the commercial power and the portable energy storage power at the same time to supply power to critical loads. The slave distribution box is only supplied by the commercial power or the portable energy storage power at the same time to avoid the phase difference damage to household appliances. This method leads to the bloated household power grid and increases the use cost of consumers.

[0004] That is, the current portable energy storage power and mobile energy storage power are off-grid power sources. The portable energy storage power and the mobile energy storage power need to consider the isolation problem with the household power grid when they are connected to the household power grid for power supply. Usually, the portable energy storage power and the mobile energy storage power are connected to the household power grid through the development of an adaptive slave distribution box. This will exist problems such as complex power grid system, difficult wiring and installation, and cannot quickly and effectively connect the portable energy storage power and the mobile energy storage power to the household power grid to supply power to the household load. SUMMARY

[0005] Therefore, the present application aims to at least partially solve one of the problems in the related art. To this end, the purpose of the present application is to provide a household power distribution device and a household power supply network.

[0006] The present application provides a household power distribution device.

The household power grid end is used for connecting to the household power grid. One end of the switch unit is electrically connected to the household power grid end, and the other end is in communication with one of the commercial power input end or the energy storage power supply end. The energy storage power receiving end is electrically connected between the commercial power input end and the switch unit. The energy storage power receiving end is used for connecting to the energy storage device, and the commercial power charges the energy storage device through the energy storage power receiving end.

[0007] The application also provides a home power supply network. The home power supply network comprises the energy storage device and the home power distribution device in any one of the above embodiments. The energy storage device can access the home power distribution device through the energy storage power supply end to supply power to the home power grid when the commercial power supply is powered off, and the energy storage device can access the home power distribution device through the energy storage power receiving end to receive the commercial power supply to charge itself when the commercial power supply is normal.

[0008] The home power distribution device of the application only needs to connect the commercial power input line of the commercial power input end and the load output line of the home power grid end, and control the on-off of the main path switch and the conduction of the switch unit to supply power to the home load connected to the home power grid end through the energy storage power supply end of the energy storage device.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0023] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples, and such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0024] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, in which like or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary, only for the purpose of explaining the present application, and cannot be understood as limiting the present application.

[0025] Please refer to Figure 1In the related art, a plurality of socket systems of a family are connected behind a circuit breaker of a power distribution box of the family, and the power supply of the loads connected to the sockets is provided by the power supply of the power distribution box. That is, the conventional power distribution box of the family only has an input port connected to the power supply, and the power supply of the loads at the power grid end of the family can be provided.

[0026] In addition, in other technologies, an energy storage power supply can be connected to the power grid of the family to supply power to the loads of the family. However, the isolation of the portable energy storage power supply and the mobile energy storage power supply needs to be considered when connecting to the power grid of the family. Usually, an adapter is developed to connect to the power grid from the power distribution box, as shown in Figure 2 This will cause problems such as complex grid system and difficult wiring installation, and the portable energy storage power supply and the mobile energy storage power supply cannot be quickly and effectively connected to the power grid of the family to supply power to the loads of the family.

[0027] Therefore, referring to Figure 3 and Figure 4 , the present application provides a power distribution device 100 of a family. The power distribution device 100 of the family includes a power input end 10, an energy storage power supply end 20, a power grid end 30, a switch unit 40, and an energy storage power receiving end 50. The power distribution device 100 of the family can be a power distribution box. The power input end 10 is used to connect to the power supply.

[0028] The energy storage power supply end 20 is used to connect to an energy storage device 200, and the energy storage device 200 is powered through the energy storage power supply end 20. The power grid end 30 is used to connect to the power grid of the family. One end of the switch unit 40 is electrically connected to the power grid end 30, and the other end is in communication with one of the power input end 10 or the energy storage power supply end 20.

[0029] That is, the power distribution device 100 of the family of the present application can control the conduction direction of the switch unit 40 to realize the selective power supply of the power supply and the energy storage device 200 to the power grid, and can avoid the risk of connecting the power supply of the energy storage device 200 to the power grid together with the power supply.

[0030] That is, the power distribution device 100 of the family of the present application can expand the application function of the energy storage device 200, so that the energy storage device 200 not only meets the power supply of outdoor activities, but also can be used as emergency power supply when the power grid of the family is powered off. In addition, the power distribution device 100 of the present application can make the energy storage device 200 connected to the energy storage power supply end 20 of the power distribution device 100 supply emergency power to the power grid of the family when the power supply is powered off, without the need to additionally match and install a corresponding power distribution box for the energy storage device 200, so that the energy storage device 200 can be simply and quickly added to the emergency power supply of the family.

[0031] The energy storage power receiving end 50 is electrically connected between the commercial power input end 10 and the switch unit 40, and the energy storage power receiving end 50 is used for connecting the energy storage device 200, and the commercial power charges the energy storage device 200 through the energy storage power receiving end 50. That is, in the case of normal commercial power, the commercial power can supply power to the household power grid, and can also charge the energy storage device 200 connected to the energy storage power receiving end 50.

[0032] Therefore, the household power distribution device 100 only needs to connect the commercial power input line of the commercial power input end 10 and the load output line of the household power grid end 30, and turn on the circuit between the energy storage device 200 and the household power grid through the control switch unit 40, so that the energy storage device 200 can quickly and effectively supply power to the household load connected to the household power grid end 30 through the energy storage power supply end 20. The installation of the household power distribution device 100 is convenient, fast, efficient and simple to operate.

[0033] Please refer to Figure 3 In some embodiments, the household power distribution device 100 further comprises a main switch 60. The commercial power input end 10 is connected to the energy storage power receiving end 50 through the main switch 60. The commercial power input end 10 is connected to the household power grid end 30 through the main switch 60 and the switch unit 40.

[0034] When the energy storage power supply end 20 is connected to the household power grid end 30 through the switch unit 40, the energy storage power supply end 20 is used to receive the electric energy of the energy storage device 200 to supply power to the household power grid.

[0035] When the commercial power input end 10 is connected to the household power grid end 30 through the main switch 60 and the switch unit 40, the commercial power input end 10 is used to provide commercial power to supply power to the household power grid.

[0036] The energy storage power receiving end 50 is connected to the commercial power input end 10 through the main switch 60, and the energy storage power receiving end 50 is used to output the commercial power to charge the energy storage device 200.

[0037] Specifically, the energy storage power supply end 20 can be set as a parallel socket. The energy storage power receiving end 50 can be set as a conventional socket. That is, the energy storage device 200 can be connected to the household power distribution device 100 through two interfaces. The energy storage power supply end 20 is an electric energy input port, and the other energy storage power receiving end 50 is an electric energy output port in the two interfaces of the household power distribution device 100. The energy storage device 200 can be connected to the two interfaces at the same time, so that the electric energy input port and the electric energy output port are arranged on the two sides of the switch unit 40.

[0038] When the mains power is off, the energy storage device 200 can supply power to the household appliances through the circuit formed by the power input port (the parallel socket) - the switch unit 40 - the socket connected to the household appliances. Understandably, the energy storage device 200 can avoid self-charging when it supplies power to the household power grid due to the presence of the switch unit 40. Specifically, when the energy storage device 200 supplies power to the household power grid, the switch unit 40 will be in communication with the energy storage power supply end 20, and at this time the energy storage device 200 will not be in communication with the energy storage power receiving end 50 through the switch unit 40, so the energy storage device 200 will not be self-charged. That is, the energy storage device 200 of the present application can avoid the problem of self-charging when the energy storage device 200 supplies power to the household power grid.

[0039] After the mains power is on, the socket connected to the household appliances is connected to the mains power through the switch unit 40, and the socket connected to the household appliances is powered by the mains power. At the same time, the mains power can charge the energy storage device 200 through the energy storage power receiving end 50, i.e. the regular socket connected to the energy storage device 200.

[0040] In addition, when the mains power is normal, if the switch unit 40 is in communication with the energy storage power supply end 20, the main switch 60 is closed to make the mains input end 10 in communication with the energy storage power receiving end 50, at this time, the energy storage device 200 can be charged by the mains power transmitted through the energy storage power receiving end 50, and at the same time, the energy storage device 200 can also discharge to the household power grid end 30 through the energy storage power supply end 20.

[0041] In this way, the combination of the switch unit 40 and the parallel socket in the household power distribution device 100 of the present application makes the energy storage device 200 access the parallel socket of the household power distribution device 100, so that the energy storage device 200 can supply emergency power to the household loads connected to the household power grid end, thereby avoiding the risk of electric shock that may be caused by the rapid access of the energy storage device 200 to the household power grid.

[0042] In some embodiments, the household power distribution device 100 further comprises a detection unit 70 and a control unit 80. The detection unit 70 is used to detect whether the mains input end 10 is off and to detect whether the energy storage power receiving end 50 is accessed by the energy storage device 200. The control unit 80 is also used to control the main switch 60 to be closed when the mains power is normal and the energy storage power receiving end 50 is accessed by the energy storage device 200, and to control the switch unit 40 to conduct the circuit between the mains power and the household power grid, so that the mains power charges the energy storage device 200 while supplying power to the household power grid.

[0043] As can be appreciated, since one end of the energy storage receiving end 50 is connected with the commercial power input end 10 and the other end is connected with the charging end of the energy storage device 200, when the commercial power is normal and the energy storage receiving end 50 is connected with the energy storage device 200, the commercial power can flow into the energy storage receiving end 50 through the commercial power input end 10, thereby charging the energy storage device 200 connected with the energy storage receiving end 50.

[0044] At this time, the control unit 80 can synchronously control the main circuit switch 60 to be closed and control the switching unit 40 to conduct the circuit between the commercial power input end 10 and the household power grid end 30, so that the commercial power can charge the energy storage device 200 and also supply power to the household power grid.

[0045] In some embodiments, the detection unit 70 is configured to detect whether the commercial power input end 10 is powered off and detect whether the energy storage power supply end 20 is connected with the energy storage device 200.

[0046] Please refer to Figures 3 to 5 In one embodiment, the control unit 80 is configured to control the switching unit 40 to conduct the circuit between the commercial power input end 10 and the household power grid end 30 when the detection unit 70 detects that the commercial power is normal and the energy storage power supply end 20 is not connected with the energy storage device 200, so that the commercial power supplies power to the household power grid.

[0047] That is, when the detection unit 70 detects that the commercial power side of the switching unit 40 has power input and the energy storage side of the switching unit 40 has no power input, the control unit 80 controls the switching unit 40 to switch to the commercial power side, so that the commercial power can supply power to the socket connected with the household electrical appliances, and the household load can be plugged into any socket connected with the household electrical appliances to work.

[0048] In another embodiment, the control unit 80 is configured to control the switching unit 40 to conduct the circuit between the energy storage power supply end 20 and the household power grid end 30 when the detection unit 70 detects that the commercial power input end 10 is powered off and the energy storage power supply end 20 is connected with the energy storage device 200, so that the energy storage device 200 supplies power to the household power grid through the energy storage power supply end 20.

[0049] That is, when the detection unit 70 detects that the commercial power side of the switching unit 40 has no power input and the energy storage side of the switching unit 40 has power input, the control unit 80 controls the switching unit 40 to switch to the energy storage side to supply power to the socket connected with the household electrical appliances, and the household load can be plugged into any socket connected with the household electrical appliances to work.

[0050] In yet another embodiment, the control unit 80 is configured to control the switching unit 40 to conduct the circuit between the mains input end 10 and the home power grid end 30 when the detection unit 70 detects that the mains is normal and the energy storage supply end 20 is connected to the energy storage device 200, so that the mains supplies power to the home power grid; or control the switching unit 40 to conduct the circuit between the energy storage supply end 20 and the home power grid end 30, so that the energy storage device 200 supplies power to the home power grid through the energy storage supply end 20.

[0051] That is, when the detection unit 70 detects that both the mains side and the energy storage side of the switching unit 40 have power input, the control unit 80 can control the switching unit 40 to switch to the mains side to supply power to the socket connected to the household appliance, and the household load can be plugged into any socket connected to the household appliance to work. When the detection unit 70 detects that both the mains side and the energy storage side of the switching unit 40 have power input, the control unit 80 can also control the switching unit 40 to switch to the energy storage side to supply power to the socket connected to the household appliance, and the household load can be plugged into any socket connected to the household appliance to work.

[0052] That is, when the detection unit 70 detects that both the mains side and the energy storage side of the switching unit 40 have power input, the control unit 80 can control the switching unit 40 to switch to the mains side or the energy storage side, so that the mains or the energy storage device 200 supplies power to the home power grid.

[0053] In some embodiments, the home power distribution device 100 further comprises a switching power supply 90. The first end of the switching power supply 90 is connected between the main switch 60 and the switching unit 40, and the second end of the switching power supply 90 is connected between the energy storage supply end 20 and the switching unit 40. The third end of the switching power supply 90 is connected to the detection unit 70. The control unit 80 is configured to determine whether the mains input end 10 is powered off and whether the energy storage supply end 20 is connected to the energy storage device 200 according to the detection result of the detection unit 70 detecting whether the first end of the switching power supply 90 or the second end of the switching power supply 90 has an electrical signal.

[0054] Specifically, the electrical signal can be a voltage signal or a current signal, which is not limited herein.

[0055] That is, the home power distribution device 100 of the present application can determine whether the input power source of the switching power supply 90 comes from the energy storage side or the mains side through the electrical signal detected by the detection unit 70, so as to determine whether the energy storage supply end 20 is connected to the energy storage device 200 and whether the mains input end 10 is powered off.

[0056] For example, if the detection unit 70 detects that the first end of the switching power supply 90 has an electrical signal and the second end of the switching power supply 90 has no electrical signal, the control unit 80 determines that the input power source of the switching power supply 90 is from the side of the commercial power supply, and thus determines that the commercial power input end 10 is not powered off, i.e., the commercial power is normal, and the energy storage power supply end 20 is not connected to the energy storage device 200.

[0057] For another example, if the detection unit 70 detects that the first end of the switching power supply 90 has no electrical signal and the second end of the switching power supply 90 has an electrical signal, the control unit 80 determines that the input power source of the switching power supply 90 is from the side of the energy storage device 200, and thus determines that the commercial power input end 10 is powered off, and the energy storage power supply end 20 is connected to the energy storage device 200.

[0058] In some embodiments, the detection unit 70 is further configured to collect a first input electrical signal received by the commercial power input end 10 and a second input electrical signal received by the energy storage power supply end 20, and the control unit 80 is further configured to calculate the power supply amount of the commercial power to the home power grid according to the first input electrical signal, and calculate the power supply amount of the energy storage device 200 to the home power grid according to the second input electrical signal.

[0059] Specifically, the first input electrical signal and the second input electrical signal can be current signals or voltage signals, which are not limited herein.

[0060] That is, the control unit 80 can sample the input current and voltage of the commercial power and the energy storage device 200 through the detection unit 70, and calculate the power supply amount of the commercial power and the energy storage device to the home power grid, so that the power supply amount of the commercial power or the energy storage device 200 to the home load can be known in real time.

[0061] In some embodiments, the home power distribution device 100 further comprises a display unit 91. The display unit 91 is configured to display the power supply amount of the commercial power to the home power grid or the power supply amount of the energy storage device 200 to the home power grid.

[0062] Specifically, the display unit 91 can be a display screen area with an appropriate size.

[0063] That is, the home power distribution device 100 of the present application can further be provided with the display unit 91, so that the power supply amount of the commercial power to the home power grid or the power supply amount of the energy storage device 200 to the home power grid can be displayed on the display unit 91 in real time, so that the user can know the current power supply situation of the commercial power or the energy storage device 200 to the home power grid.

[0064] In some embodiments, the switching unit 40 of the present application can be a relay. Specifically, as shown in Figure 4 the relay of the present application can be a single-pole double-throw relay.

[0065] Thus, the home power distribution device 100 of the present application can control the relay to switch to the energy storage side or the mains side through the intelligent control module 412, so that the mains or the energy storage device supplies power to the home load of the home power grid.

[0066] In some embodiments, the relay is configured to maintain the connection state of the last active power supply side when both input sides are de-energized.

[0067] That is, for example, if the default initial position of the relay is the common contact connection switched to the mains side, when only the mains side is energized, after the common contact connection is switched to the mains side, if the mains is de-energized again, both input sides of the relay are de-energized, that is, both input sides are de-energized, the relay can maintain the switching state before the mains is de-energized, that is, the common contact of the relay maintains the state of switching to the mains side.

[0068] For another example, if the default initial position of the relay is the common contact connection switched to the mains side, when only the energy storage side is energized, after the common contact connection is switched to the energy storage side, if the energy storage side is de-energized again, both input sides of the relay are de-energized, that is, both input sides are de-energized, the relay can maintain the switching state before the energy storage side is de-energized, that is, the common contact of the relay maintains the state of switching to the energy storage side.

[0069] Thus, the relay of the present application is configured to maintain the connection state of the last active power supply side when both input sides are de-energized, that is, the relay has a "memory keeping" function, which can reduce invalid switching, optimize power supply continuity and prolong the service life of the device.

[0070] In some embodiments, the home power distribution device 100 is wirelessly connected with a mobile terminal, the control unit 80 is configured to control the power supply between the mains and the home power grid and the power supply between the energy storage device and the home power grid, and transmit the power supply conditions to the mobile terminal through communication for display on the mobile terminal. The mobile terminal can remotely send control instructions to the control unit 80 to control the closing and opening of the main switch 60 and the conduction direction of the switch unit 40.

[0071] That is, the home power distribution device 100 of the present application can interact with the mobile terminal and remotely control the mobile terminal through wireless network (WiFi) or short distance wireless connection (Bluetooth). The mobile terminal can be, for example, a mobile phone, an iPad, a computer, a vehicle, or other electronic devices.

[0072] Correspondingly, the present application can remotely monitor the information such as the closing and opening of the main switch 60 and the conduction direction of the switch unit 40 through the application program on the mobile terminal, so as to realize remote control of switching the mains or the energy storage device to supply power to the home load of the home power grid.

[0073] Please refer toFigure 3 and Figure 4 In some embodiments, the home power grid end 30 further comprises a plurality of output branches 31. The output branch 31 comprises an electric energy input end 311, a home load access end 312 and a branch switch 313. The electric energy input end 311 is connected with the output end of the switch unit 40, and the branch switch 313 is arranged between the electric energy input end 311 and the home load access end 312, for controlling the on-off of the passage between the electric energy input end 311 and the home load access end 312.

[0074] Specifically, the bathroom, the room 1, the room 2, the living room and the kitchen and other areas in the user's home are each provided with a corresponding output branch 31, that is, each home area is provided with a home load access end 312 corresponding to the different home areas in the home power distribution device 100, and the electric energy consumption of the home load of each home area can be controlled by the closing and opening of the branch switch 313.

[0075] For example, when the branch switch 313 corresponding to the bathroom is closed, the passage between the electric energy input end 311 and the home load access end 312 in the bathroom is turned on, and the home load in the bathroom, such as electric light, heater and the like, can be connected to the alternating current to normally work. When the branch switch 313 corresponding to the bathroom is opened, the passage between the electric energy input end 311 and the home load access end 312 in the bathroom is turned off, and at this time the home load in the bathroom, such as electric light, heater and the like, cannot be connected to the alternating current to stop working.

[0076] In this way, the home power distribution device 100 of the present application can realize the electric energy consumption control of the load in different home areas by arranging a plurality of output branches 31.

[0077] The present application further provides a home power supply network. The home power supply network comprises the energy storage device 200 and the home power distribution device 100 of any one of the above-mentioned embodiments.
