Description

Technical Field

[0001] This application relates to the technical field of household power supply, and particularly relates to an intelligent control socket and a household power supply network. Background Art

[0002] In the related art, a household power distribution box is configured in the household power grid of the household power supply network. One end of the household power distribution box is connected to the mains power supply, and the other end is connected to the household power grid. The household power distribution box consists of a main circuit breaker and multiple sub - circuit breakers. Some sub - circuit breakers are connected to ordinary sockets at the back end, and household loads obtain power through the ordinary sockets. When the mains power supply is cut off, the entire household power grid will lose power completely and cannot continue to supply power to household loads.

[0003] In addition, if a portable energy storage device is used for household power consumption or emergency power consumption, since a conventional portable energy storage device only has an off - grid output function, when the portable energy storage device is directly connected to the household power grid, when the mains power supply and the portable energy storage device output simultaneously, the alternating current of both will damage household appliances due to the phase difference problem. That is to say, directly connecting a portable energy storage device to the household power grid will pose an electric shock risk and a grid - connection risk. As Figure 1 shown, the portable energy storage device cannot directly supply power to the entire household power grid or a partial power grid by connecting to an ordinary socket.

The change - over switch can selectively connect the household load to the mains power supply, or can selectively connect the household load to the energy storage device. The household load is only connected to one of the mains power supply or the energy storage device at the same time. The change - over switch is used to connect the circuit between the mains power supply and the household load when the mains power supply is normal, and disconnect the circuit between the energy storage device and the household load; and is used to disconnect the circuit between the mains power supply and the household load when the mains power supply is cut off, and connect the circuit between the energy storage device and the household load.

[0006] The present application also provides a home power supply network.

[0030] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0031] Please refer to Figure 2 , the present application provides an intelligent control socket 100. The intelligent control socket 100 is arranged between the mains power and the household load. The intelligent control socket 100 is also connected to an energy storage device 200. A changeover switch 10 is provided inside the intelligent control socket 100. The changeover switch 10 can selectively connect the household load to the mains power, or can selectively connect the household load to the energy storage device 200. The household load is only connected to one of the mains power or the energy storage device 200 at the same time. The changeover switch 10 is used to connect the circuit between the mains power and the household load when the mains power is normal, and disconnect the circuit between the energy storage device 200 and the household load; and is used to disconnect the circuit between the mains power and the household load when the mains power fails, and connect the circuit between the energy storage device 200 and the household load.

[0032] Specifically, since the intelligent control socket 100 of the present application is provided with a changeover switch 10, the circuit connection route between the household load and the mains power supply and the energy storage device 200 can be flexibly switched through the changeover switch 10, and the electric shock risk and grid connection risk when the mains power supply and the energy storage device 200 are simultaneously connected to the household power grid can be avoided.

[0033] In this way, the intelligent control socket 100 of the present application can be respectively connected to the mains power supply, the energy storage device 200 and the household load. The changeover switch 10 is provided in the intelligent control socket 100 to realize the switching and loading of the mains power supply and the energy storage device 200, and the electric shock risk and grid connection risk when the mains power supply and the energy storage device 200 are simultaneously connected to the household power grid can be avoided.

[0034] The changeover switch 10 provided in the intelligent control socket 100 of the present application can be a manual control switch or an intelligent control switch, and no limitation is made here.

[0035] In one embodiment, the changeover switch 10 is a manual control switch, and a control button electrically connected to the changeover switch 10 is provided on the intelligent control socket 100.

[0036] Specifically, when the control button is in the first state, it can be set that at this time the control button can control the changeover switch 10 to be connected to the mains power supply side, so as to connect the circuit between the mains power supply and the household load.

[0037] When the control button is in the second state, it can be set that at this time the control button can control the changeover switch 10 to be connected to the energy storage side, so as to connect the circuit between the energy storage device 200 and the household load.

[0038] In this way, the present application can manually control the connection direction of the changeover switch 10 through the control button, so as to avoid the electric shock risk and grid connection risk when the mains power supply and the energy storage device 200 are simultaneously connected to the household power grid.

[0039] In another embodiment, the changeover switch 10 is an intelligent control switch, and a changeover control unit electrically connected to the changeover switch 10 is provided on the intelligent control socket 100. The changeover control unit is used to detect whether there are electrical signals on the energy storage side and the mains power supply side of the changeover switch, and control the conduction route of the changeover switch according to the detection result.

[0040] Specifically, the electrical signal can be a voltage signal or a current signal, and no limitation is made here.

[0041] For example, when the switching control unit detects that there is voltage on the mains side of the changeover switch 10 and no voltage on the energy storage side, it indicates that the mains power is normal. At this time, the switching control unit can automatically control the changeover switch 10 to connect to the mains side, thereby connecting the circuit between the mains power and the household load, and the mains power provides electrical energy for the household load. When the switching control unit detects that there is no voltage on the mains side of the changeover switch 10 and there is voltage on the energy storage side, it indicates that the mains power has lost power. At this time, the switching control unit can automatically control the changeover switch 10 to connect to the energy storage side, thereby connecting the circuit between the energy storage device 200 and the household load, and the energy storage device 200 provides electrical energy for the household load.

[0042] In this way, the present application can intelligently control the connection direction of the changeover switch 10 through the switching control unit without manual operation, and can more intelligently avoid the electric shock risk and grid connection risk when the mains power and the energy storage device 200 are simultaneously connected to the household power grid.

[0043] Please refer to Figure 2 and Figure 3 , in some embodiments, the intelligent control socket 100 is electrically connected to the household power distribution device 300. The household power distribution device 300 includes a mains input end 310, a household power grid end 320, and a power distribution management module 330. The mains input end 310 is used to access the mains power. The household power grid end 320 is used to access the household power grid, and the household power grid can access either the mains power or the energy storage device 200. The power distribution management module 330 includes an output main path 331 and a plurality of output branches 332 electrically connected to the output main path 331, and at least one output branch 332 is connected with the intelligent control socket 100.

[0044] An intelligent circuit breaker 3312 is provided on the output main path 331. The intelligent circuit breaker 3312 includes a main path switch 33121 and a control module 33122. The main path switch 33121 is electrically connected to the control module 33122. One end of the main path switch 33121 is connected to the mains input end 310, and the other end of the main path switch 33121 is connected to the household power grid end 320. The control module 33122 is used to control the main path switch 33121 to close and the changeover switch 10 to connect the circuit between the mains power and the household load when the mains power is normal and the household power grid is not connected to the energy storage device 200, so that the mains power supplies power to the household power grid; and in the case of mains power failure, after controlling the main path switch 33121 to disconnect, control the changeover switch 10 to connect the circuit between the energy storage device 200 and the household load; and in the case of the mains power recovering after a power failure, after controlling the changeover switch 10 to connect the circuit between the mains power and the household load, re-control the main path switch 33121 to close.

[0045] Specifically, in the present application, an intelligent circuit breaker 3312 is provided in the household power distribution device 300. The intelligent circuit breaker 3312 includes a main circuit switch 33121 and a control module 33122. When the mains power is normal and the energy storage device 200 is not connected to the household power grid, the control module 33122 can control the main circuit switch 33121 to close and the changeover switch 10 to connect the circuit between the mains power and the household load, so that the mains power supplies power to the household power grid. When the mains power fails, the control module 33122 can control the main circuit switch 33121 to open and the changeover switch 10 to connect the circuit between the energy storage device 200 and the household load, which can realize the automatic closing and switching of the main circuit switch 33121 intelligently and the intelligent control of the connection direction of the changeover switch 10.

[0046] At this time, the intelligent control socket 100 of the present application can play the role of automatically switching to supply electric energy to the household load by the mains power or the energy storage device 200. When the mains power exists, the control module 33122 can control the changeover switch 10 inside the intelligent control socket 100 to switch to the mains power side to supply power to the household load. When the mains power fails and the energy storage device supplies power, the control module 33122 can control the changeover switch 10 inside the intelligent control socket 100 to switch to the energy storage side to supply power to the household load.

[0047] In addition, if the main circuit switch 33121 is closed when the mains power fails and the energy storage device 200 is connected to the household power grid, and at this time the mains power is suddenly connected, the energy storage device 200 and the mains power will input alternating current to the household power grid at the same time, and the phase difference between the two will damage equipment such as household loads. Therefore, when the energy storage device 200 supplies power to the household load, if the mains power fails and then resumes, the control module 33122 can first control the changeover switch 10 inside the intelligent control socket 100 to switch to the mains power side to supply power to the household load, and then re-control the main circuit switch 33121 to close, which can avoid the grid connection risk caused by the alternating current output by the mains power and the energy storage device 200 when the mains power is suddenly connected to the household power grid, resulting in damage to equipment such as household loads or grid instability.

[0048] Please refer to Figures 3 to 6 , in some embodiments, a branch switch 3321 is provided on the output branch 332. The intelligent control socket 100 is connected in series between the main circuit switch 33121 of the household power distribution device 300 and the branch switch 3321 of the household power distribution device 300; or, the intelligent control socket 100 is connected in series between the branch switch 3321 of the household power distribution device 300 and a preset number of ordinary sockets in the household power distribution device 300.

[0049] That is to say, the connection position of the intelligent control socket 100 can change according to different power supply requirements. The intelligent control socket 100 can be selectively connected to different positions according to the user's demand for emergency power supply for different numbers of household loads.

[0050] Specifically, in one embodiment, as Figure 4 shown, the intelligent control socket 100 is connected in series between the main circuit switch 33121 and the branch circuit switch 3321. When all the household loads corresponding to the user's household power distribution device 300 have emergency power backup requirements and the total current flowing through all the household loads is less than or equal to the rated current flowing through the intelligent control socket 100, the user can connect the intelligent control socket 100 in series between the main circuit switch 33121 and the branch circuit switch 3321 to perform emergency power backup for all the household loads.

[0051] In another embodiment, as Figure 5 shown, the intelligent control socket 100 is connected in series between the branch circuit switch 3321 and a preset number of ordinary sockets. When only some of the household loads corresponding to the user's household power distribution device 300 have emergency power backup requirements, and the partial household loads are connected to multiple ordinary sockets in a part of the household power distribution device 300, the user can connect the intelligent control socket 100 in series between the branch circuit switch 3321 and the multiple ordinary sockets in the part to perform emergency power backup for the partial household loads.

[0052] Among them, the preset number of ordinary sockets can be multiple ordinary sockets in the part with emergency power backup requirements. For example, when the number of multiple ordinary sockets in the part with emergency power backup requirements is 3, the preset number is 3; when the number of multiple ordinary sockets in the part with emergency power backup requirements is 4, the preset number is 4; when the number of multiple ordinary sockets in the part with emergency power backup requirements is 5, the preset number is 5.

[0053] Please refer to Figure 3 , the output main circuit 331 is electrically connected to a plurality of output branch circuits 332. The output branch circuit 332 includes a power input end 3322, a household load access end 3323, and a branch circuit switch 3321. The power input end 3322 is connected to the main circuit switch 33121. The branch circuit switch 3321 is arranged between the power input end 3322 and the household load access end 3323 for controlling the on / off of the path between the power input end 3322 and the household load access end 3323. Among them, the branch circuit switch 3321 can be a circuit breaker.

[0054] Specifically, as Figure 3 shown, in the bathroom, room 1, room 2, living room, and kitchen in the user's home, there is a corresponding output branch circuit 332. That is, each household area is correspondingly provided with a household load access end 3323 in the power distribution management module 330 of the household power distribution device 300 to be electrically connected to the household loads in different household areas. The power consumption of the household loads in each household area can be controlled by the closing and opening of the branch circuit switch 3321.

[0055] For example, when the branch switch 3321 corresponding to the bathroom is closed, the path between the power input end 3322 where the bathroom is located and the household load access end 3323 is conducted, and household loads in the bathroom such as electric lights and heaters can be connected to alternating current for normal operation. When the branch switch 3321 corresponding to the bathroom is opened, the path between the power input end 3322 where the bathroom is located and the household load access end 3323 is disconnected, and at this time, household loads in the bathroom such as electric lights and heaters cannot be connected to alternating current and thus stop working.

[0056] In addition, when the energy storage device 200 is quickly connected to the household power grid end 320 through the intelligent control socket 100 in the household area to supply power to the household loads in the household power grid, the power supply power of the energy storage device 200 is determined by the maximum power of the used energy storage device 200 and the overcurrent capacity of the connected intelligent control socket 100 and the branch switch 3321 on the branch where the intelligent control socket 100 is located.

[0057] In this way, the power distribution management module 330 in the household power distribution device 300 of the present application can realize the power consumption control of the loads in different household areas by setting multiple output branches 332.

[0058] In some embodiments, the changeover switch 10 is a relay.

[0059] Specifically, a relay is an electrical switch device that controls a large current with a small current. Its core function is to isolate the control circuit from the controlled circuit and realize signal conversion, amplification or multi-channel automatic control. A relay mainly consists of two parts: a control end (coil side) and a controlled end (contact side). The control end (coil side) is an electromagnet system, which may include a coil and an iron core. The controlled end (contact side) is a mechanical switch system, which may include a moving contact, a static contact and a spring.

[0060] Please refer to Figure 6 , in some embodiments, the intelligent control socket 100 includes an energy storage input end 20 and an energy storage output end 30. The energy storage input end 20 is used to connect to the energy storage device 200 to charge the energy storage device 200. The energy storage output end 30 is used to connect to the energy storage device 200 to discharge the energy storage device 200.

[0061] That is to say, at this time, the intelligent control socket 100 of the present application can be divided into two mutually independent energy storage plug-in interfaces. That is, the energy storage input end 20 is a charging plug-in interface, and the charging plug-in interface can be a triangular socket as shown in Figure 6 . The energy storage output end 30 is a discharging plug-in interface, and the discharging plug-in interface can be another triangular socket as shown in Figure 6 . The two are mutually independent and do not interfere with each other.

[0062] Thus, the intelligent control socket 100 of the present application can distinguish different interfaces for charging and discharging of the energy storage device 200 through the energy storage input end 20 and the energy storage output end 30, which is beneficial to improving the user experience.

[0063] Please refer to Figure 7 , in some embodiments, the intelligent control socket 100 further includes a mains power end 40, a household load end 50, and a first switching switch 11. The mains power end 40 is connected to the energy storage input end 20, and the household load end 50 is selectively connected to the mains power end 40 or the energy storage output end 30 through the first switching switch 11. When the mains power is normal, the household load end 50 is connected to the mains power end 40 through the first switching switch 11, and the mains power input by the mains power end 40 supplies power to the household load end 50, and the mains power end 40 synchronously charges the energy storage device 200. When the mains power fails, the household load end 50 is connected to the energy storage output end 30 through the first switching switch 11, and the energy storage output end 30 supplies power to the household load end 50.

[0064] Specifically, the first switching switch 11 can ensure physical mutual exclusion between the mains power end 40 and the energy storage output end 30, avoid simultaneous connection of the mains power end 40 and the energy storage output end 30, and prevent reverse power transmission.

[0065] The first switching switch 11 can be a single-pole double-throw switch. As Figure 7 shown, the first end of the first switching switch 11 is connected to the household load end 50, and the second end of the first switching switch 11 is selectively connected to the mains power end 40 or the energy storage output end 30.

[0066] That is, when the mains power is normal, the second end of the first switching switch 11 can be controlled to select to connect to the mains power end 40, that is, the first switching switch 11 connects the mains power end 40 and the household load end 50, and the mains power can supply power to the household load end 50. At this time, the mains power end 40 is connected to the energy storage input end 20, so the mains power can simultaneously charge the energy storage device 200.

[0067] When the mains power fails, the second end of the first switching switch 11 can be controlled to select to connect to the energy storage output end 30, that is, the first switching switch 11 connects the energy storage output end 30 and the household load end 50, so that the energy storage device 200 can discharge through the energy storage output end 30, and thus supply power to the household load end 50 through the energy storage output end 30.

[0068] Thus, the intelligent control socket 100 of the present application can realize the charging and discharging processes of the energy storage device 200 by respectively arranging the energy storage input end 20 and the energy storage output end 30.

[0069] In some embodiments, the energy storage device 200 includes a charging wire 210 and a discharging wire 220. The charging wire 210 is connected to the energy storage input end 20 for charging, and the discharging wire 220 is connected to the energy storage output end 30 for discharging.

[0070] That is to say, the energy storage device 200 of the present application is correspondingly provided with a charging wire 210 and a discharging wire 220, which are respectively connected to the energy storage input end 20 and the energy storage output end 30 of the intelligent control socket 100, so as to realize the charging process and the discharging process of the energy storage device 200. When the energy storage device 200 is in the discharging process, the energy storage device 200 can supply emergency power to household loads in the case of power failure of the mains power.

[0071] Please refer to Figure 8 , in some embodiments, the intelligent control socket 100 includes an energy storage input / output end 60, and the energy storage input / output end 60 is connected to the energy storage device 200 to charge or discharge the energy storage device 200.

[0072] That is to say, the intelligent control socket 100 of the present application can also be provided with only one energy storage input / output end 60 as an energy storage plug-in interface, and the energy storage device 200 realizes the charging or discharging process of the energy storage device 200 by plugging into this energy storage plug-in interface.

[0073] Please refer to Figure 8 , in some embodiments, the intelligent control socket 100 further includes a mains power end 40, a household load end 50, a second switching switch 12 and a third switching switch 13. The household load end 50 is selectively connected to the mains power end 40 or the energy storage input / output end 60 through the second switching switch 12. The energy storage input / output end 60 is selectively connected to the mains power end 40 or the household load end 50 through the third switching switch 13. When the mains power is normal, the household load end 50 is connected to the mains power end 40 through the second switching switch 12, and the energy storage input / output end 60 is connected to the mains power end 40 through the third switching switch 13. Both the household load end 50 and the energy storage input / output end 60 are charged by the mains power end 40. When the mains power fails, the energy storage input / output end 60 is connected to the household load end 50 through the third switching switch 13 and the second switching switch 12, and the household load end 50 is powered by the energy storage input / output end 60.

[0074] Specifically, both the second switching switch 12 and the third switching switch 13 can be single-pole double-throw switches. As Figure 8 shown, the first end of the second switching switch 12 is connected to the household load end 50, and the second end of the second switching switch 12 is selectively connected to the mains power end 40 and the third switching switch 13. The first end of the third switching switch 13 is connected to the energy storage input / output end 60, and the second end of the third switching switch 13 is selectively connected to the mains power end 40 and the second switching switch 12.

[0075] When the mains power is normal, the second terminal of the third changeover switch 13 can be controlled to selectively connect to the mains terminal 40, so that the third changeover switch 13 connects the energy storage input / output terminal 60 to the mains terminal 40. The second terminal of the second changeover switch 12 is selectively connected to the mains terminal 40, so that the second changeover switch 12 connects the household load terminal 50 to the mains terminal 40, realizing the process that both the household load and the energy storage device 200 can be charged through the mains power.

[0076] When the mains power fails, the second terminal of the third changeover switch 13 can be controlled to selectively connect to the second changeover switch 12, and the second terminal of the second changeover switch 12 is also controlled to selectively connect to the third changeover switch 13. At this time, the energy storage input / output terminal 60 is connected to the household load terminal 50 through the third changeover switch 13 and the second changeover switch 12, realizing the process that the household load terminal 50 is powered by the energy storage input / output terminal 60.

[0077] That is to say, the intelligent control socket 100 of the present application can share one interface for the energy storage input terminal and the energy storage output terminal, that is, only one energy storage input / output terminal 60 is provided, so that the energy storage device 200 can be charged or discharged separately through the energy storage input / output terminal 60.

[0078] Please refer to Figure 2 , in some embodiments, the changeover switch 10 is a single-pole double-throw switch.

[0079] Specifically, a set of moving contacts in the single-pole double-throw switch can switch two stationary contacts, so that the changeover switch 10 can connect the circuit between the mains power and the household load or the circuit between the energy storage device 200 and the household load.

[0080] In some embodiments, a baffle or a protection door can be provided inside the jack of the intelligent control socket 100 of the present application. Only when the two metal pieces of the plug are inserted simultaneously and evenly, the baffle will be pushed open and powered on, that is, the intelligent control socket 100 is set as an anti-terminal-touch intelligent control socket 100 to prevent users (especially children) from directly contacting the live jacks with fingers or metal objects, thereby avoiding the risk of electric shock.

[0081] For example, as Figure 6 shown, for the intelligent control socket with a three-hole plug set with two parts, a baffle is provided inside each of the L (live wire) and N (neutral wire) jacks of the intelligent control socket 100. The two baffles are designed by mechanical linkage (such as a spring or a lever structure). Only when the two metal pieces of the plug are inserted synchronously and evenly, can the baffle be pushed open and powered on. An independent baffle is provided inside the PE jack of the intelligent control socket 100, that is, the baffle of the ground wire jack is controlled separately, and only after the ground wire pin of the plug is inserted, the L / N will be allowed to be powered on, thereby preventing users (especially children) from directly contacting the live jacks with fingers or metal objects, and thus avoiding the risk of electric shock.

[0082] Please refer toFigure 9 , in some embodiments, the control module 33122 includes a switching power supply 331221. The first input terminal of the switching power supply 331221 is electrically connected to the mains input terminal 310, and the second input terminal of the switching power supply 331221 is electrically connected to the home power grid terminal 320. The switching power supply 331221 can receive electrical energy provided by the mains or the home power grid to drive the main circuit switch 33121 to open or close.

[0083] Specifically, when the mains is normal and no energy storage device 200 is connected to the home power grid terminal, the control module 33122 of the present application can maintain normal operation through the electrical energy provided by the mains connected through the mains input terminal 310, so as to drive the control main circuit switch 33121 to remain closed. When the mains power fails and an energy storage device 200 is connected to the home power grid, the control module 33122 of the present application can also maintain normal operation through the electrical energy provided by the energy storage device 200 connected to the home power grid, so as to drive the control main circuit switch 33121 to remain open, which can avoid the power supply circuit of the mains and the power supply circuit of the energy storage device 200 at the home power grid terminal being combined together when the mains power comes back, resulting in a grid connection risk.

[0084] That is to say, a switching power supply 331221 can be provided inside the control module 33122. When either the mains input terminal 310 or the home power grid terminal 320 has power, it can automatically provide electrical energy for the switching power supply 331221, enabling the switching power supply 331221 to start working, so that either the mains or the home power grid can provide the electrical energy required for the internal circuit of the control module 33122.

[0085] In some embodiments, the control module 33122 further includes a switching power supply 331221 and a backup power supply 331222. One end of the backup power supply 331222 is connected to the mains input terminal 310, and the other end of the backup power supply 331222 is connected to the third input terminal of the switching power supply 331221. The backup power supply 331222 is used to be charged through the mains when the mains is normal, and is used to provide electrical energy for the switching power supply 331221 when the mains power fails, so as to drive the main circuit switch 33121 to open.

[0086] Specifically, the backup power supply 331222 is arranged between the mains input terminal 310 and the switching power supply 331221. When the mains exists, the mains can charge the backup power supply 331222, and at the same time, the mains can also supply power to the switching power supply 331221, and the switching power supply 331221 drives the control main circuit switch 33121 to close. When the mains power fails, if the main circuit switch 33121 is in the closed state, the electrical energy provided by the backup power supply 331222 for the switching power supply 331221 can be used to drive the switching power supply 331221 to drive the control main circuit switch 33121 to open, realizing the self - recovery disconnection function of the main circuit switch 33121.

[0087] After the main circuit switch 33121 is controlled to open by the electric energy provided by the backup power supply 331222, if the energy storage device 200 is connected to the household power grid at this time, the AC output function of the energy storage device 200 can be turned on, and through a smart control socket 100 in any room of the household power grid. For example, the energy storage device 200 can be connected to one smart control socket 100 in the living room, or it can also be connected to the smart control socket 100 in other rooms. The connection position is freely determined according to the convenience of the user or the power consumption, and the alternating current of the energy storage device 200 is supplied to the household power grid to provide AC power supply for the whole family. Among them, the smart control socket 100 can be a special smart control socket 100 set to be available for the energy storage device 200 to be powered and connected.

[0088] In some embodiments, the backup power supply 331222 includes a battery or a capacitor.

[0089] That is to say, the backup power supply 331222 of the present application can use a rechargeable battery such as a lithium battery as an energy storage element, or can also use a super capacitor such as an electric double layer capacitor as an energy storage element to pre-store the electric energy required to drive and control the main circuit switch 33121 to open.

[0090] In some embodiments, the control module 33122 further includes a detection unit 331223 and a control unit 331224. The detection unit 331223 is electrically connected to the control unit 331224. The detection unit 3122 is used to detect whether the mains input end 310 loses power and to detect whether the energy storage device 200 is connected to the household power grid. The control unit 331224 is used to control the main circuit switch to open when the detection unit 331223 detects that the mains input end 310 loses power; and the control unit 331224 is used to control the main circuit switch 33121 to close when the detection unit 331223 detects that the mains is normal and the energy storage device 200 is not connected to the household power grid, so that the mains supplies power to the household power grid.

[0091] Specifically, the detection unit 331223 can be directly electrically connected to the household power grid end 320 and the mains input end 310 respectively to detect whether the mains loses power and whether the energy storage device 200 is connected to the household power grid.

[0092] For example, if the detection unit 331223 detects that there is power at the mains input end 310, it means that the mains has not lost power, that is, the mains is normal. If the detection unit 331223 detects that the mains input end 310 has lost power, it means that the mains has lost power. If the detection unit 331223 detects that the mains has lost power and there is power at the household power grid end 320, then the energy storage device 200 has been connected to the household power grid. If the detection unit 331223 detects that the mains has lost power and there is no power at the household power grid end 320, then the energy storage device 200 has not been connected to the household power grid.

[0093] Thus, in the present application, a detection unit 331223 is provided in the control module 33122, which can detect whether the mains power supply connected to the home power grid is powered off and whether an energy storage device 200 is connected to the home power grid terminal.

[0094] In some embodiments, the control unit 3121 is configured to control the main circuit switch 33121 to remain in the open state when the mains power input terminal 310 is in a power-off state and the energy storage device 200 is connected to the home power grid; or the control unit 3121 is configured to control the main circuit switch 33121 to close when the home power grid is not connected to the energy storage device 200 and the mains power input terminal 310 is in a powered state.

[0095] Specifically, when the mains power input terminal 310 is in a power-off state and the energy storage device 200 is connected to the home power grid, the control unit 3121 controls the main circuit switch 33121 to remain in the open state, which can avoid the power supply circuit of the mains power and the power supply circuit of the energy storage device 200 at the home power grid terminal 320 being combined together when the mains power comes back on, resulting in a grid connection risk.

[0096] When the home power grid is not connected to the energy storage device 200 and the mains power input terminal 310 is in a powered state, controlling the main circuit switch 33121 to close can resume power supply to the home power grid through the mains power.

[0097] Please refer to Figure 9 , in some embodiments, the control module 33122 further includes a driving unit 331225. The control unit 331224 is respectively connected to the detection unit 331223 and the driving unit 331225, and the driving unit 331225 is connected to the main circuit switch 33121. The control unit 3121 is configured to control the driving unit 331225 to operate to disconnect the main circuit switch 33121 and control the energy storage device 200 to supply power to the home power grid when the detection unit 3122 detects that the mains power input terminal 310 is powered off and the home power grid is connected to the energy storage device 200.

[0098] Specifically, the driving unit 331225 can be a motor or other driving devices, which is not limited herein.

[0099] When the mains power supply is cut off, as long as the detection unit 331223 detects the mains power supply cut-off, it can control the driving unit 331225 to drive the main circuit switch 33121 to disconnect, so that the home power grid is disconnected from the mains power supply, and the home power grid becomes an independent module. At this time, if the user has an energy storage device 200 at home, the energy storage device 200 can be connected to the home power grid and the AC output function of the energy storage device 200 can be turned on. The way the energy storage device 200 is connected to the home power grid can be to insert the energy storage device 200 into any intelligent control socket 100 used at home, so as to connect to the home power grid. That is to say, the present application can supply the alternating current of the energy storage device 200 to the home power grid through an intelligent control socket 100 in any room in the home, so as to supply alternating current to the whole home.

[0100] For example, as Figure 3 shown, the energy storage device 200 can be connected to one intelligent control socket 100 in the living room, or can also be connected to the intelligent control socket 100 in other rooms. The present application can determine the connection position of the energy storage device 200 according to the convenient connection position of the user, and can also determine the connection position of the energy storage device 200 according to the maximum power of the used energy storage device 200.

[0101] In this way, when the detection unit 331223 detects that the mains power input end 310 is powered off and the home power grid is connected with an energy storage device 200, the control unit 331224 can control the driving unit 331225 to work to disconnect the main circuit switch 33121, and control the energy storage device 200 to supply power to the home power grid, that is, the control module 33122 composed of the control unit 331224, the detection unit 331223 and the driving unit 331225 can realize the switching of the power supply source of the home power grid.

[0102] Please refer to Figure 10 , in some embodiments, the driving unit 331225 includes a mechanical transmission unit 3312251 and a mechanical locking unit 3312252. The mechanical locking unit 3312252 is connected to the mechanical transmission unit 3312251, and the mechanical transmission unit 3312251 and the mechanical locking unit 3312252 are connected to the control unit 331224. The control unit 331224 is further configured to control the mechanical transmission unit 3312251 to move to disconnect the main circuit switch 33121 when the mains power input end 310 loses power, and control the mechanical locking unit 3312252 to lock the mechanical transmission unit 3312251 within a preset time after the energy storage device 200 starts to supply power to the home power grid to keep the main circuit switch 33121 in the disconnected state.

[0103] Specifically, the mechanical transmission unit 3312251 can be a transmission shaft. Correspondingly, the control module 33122 further includes a transmission shaft control circuit in which a control unit 331224 is connected to the transmission shaft. When the mains power supply is cut off, as long as the detection unit 331223 detects the power cut of the mains power supply, it can control the transmission shaft to rotate through the transmission shaft control circuit, so as to control the main circuit switch 33121 to disconnect, making the home power grid disconnected from the mains power supply and turning the home power grid into an independent module.

[0104] The preset time can be, for example, 0S, 0.1S, 0.2S, 0.3S, 0.4S, 0.5S, 0.6S, 0.7S, 0.8S or 1S, which is not limited here. When the preset time is 0S, the control unit 331224 can, after the power supply at the mains power input end 310 is cut off and the energy storage device 200 starts to supply power to the home power grid, simultaneously control the mechanical locking unit 3312252 to lock the mechanical transmission unit 3312251, so as to keep the main circuit switch 33121 in the off state. When the preset time is 0.1S, the control unit 331224 can control the mechanical locking unit 3312252 to lock the mechanical transmission unit 3312251 within 0.1S after the mains power is cut off and the energy storage device 200 starts to supply power to the home power grid, so as to keep the main circuit switch 33121 in the off state.

[0105] It can be understood that when the mains power supply is cut off and the energy storage device 200 provides alternating current to the home power grid instantaneously or within the preset time, the control unit 331224 controls the mechanical locking unit 3312252 to lock the mechanical transmission unit 3312251, which can lock the mechanical transmission unit 3312251 in the rotational state when the main circuit switch 33121 is in the off state, preventing the user from accidentally touching the main circuit switch 33121 to connect the home power grid to the mains power supply when the energy storage device 200 supplies power to the home power grid, resulting in a failure of the energy storage device 200 and causing an electrical hazard.

[0106] Specifically, after the main circuit switch 33121 is disconnected and the energy storage device 200 supplies power to the home power grid, the detection unit 331223 can simultaneously collect the current values at the mains power input end 310 and the home power grid end 320, and the control unit 331224 judges whether there is power on both sides of the mains power input end 310 and the home power grid end 320 according to the current values.

[0107] If the current value sampled by the detection unit 331223 at the mains input end 310 is 0, and when the current value sampled by the detection unit 331223 at the household power grid end 320 is not 0 or is a relatively large current value, the control unit 331224 can determine that there is no power at the mains input end 310 at this time, the mains is still in a power-off state, and the household power grid end 320 has power. Therefore, the control unit 331224 can control the mechanical locking unit 3312252 to lock the mechanical transmission unit 3312251 to keep the main circuit switch 33121 in the off state, and record that the household power distribution device 100 is in the energy storage emergency power supply state at this time.

[0108] If the current value sampled by the detection unit 331223 at the mains input end 310 is not 0 or is a relatively large current value, and when the current value sampled by the detection unit 331223 at the household power grid end 320 is not 0 or is a relatively large current value, the control unit 331224 can determine that there is power at the mains input end 310 at this time, the mains is in a power-on state, and the household power grid end 320 has power. Therefore, the control unit 331224 can control the mechanical locking unit 3312252 to lock the mechanical transmission unit 3312251 to keep the main circuit switch 33121 in the off state, and remind the user that the mains has come back on, so as to facilitate the user to timely turn off the AC output function of the energy storage device 200 or disconnect the energy storage device 200 from the energy storage access end 30, and then operate through manual or the application program (APP) on the mobile terminal 400 to turn off the main circuit switch 33121, and restore the mains to supply power to the household power grid again.

[0109] If the current value sampled by the detection unit 331223 at the mains input end 310 is not 0 or is a relatively large current value, and when the current value sampled by the detection unit 331223 at the household power grid end 320 is 0, the control unit 331224 can determine that there is power at the mains input end 310 at this time, the mains is in a power-on state, and the household power grid end 320 has no power, indicating that the energy storage device 200 has turned off the AC output function or has disconnected the energy storage device 200 from the energy storage access end 30, and the energy storage device 200 stops supplying power to the household power grid. Therefore, at this time, the control unit 331224 can directly control to close the main circuit switch 33121 and restore the mains to supply power to the household power grid again.

[0110] Please refer to Figure 9 and Figure 10, the control unit 331224 is electrically connected to the first end of the detection unit 331223. The second end of the detection unit 331223 is electrically connected to the home power grid terminal 320, and the third end of the detection unit 331223 is electrically connected to the mains input terminal 310. The detection unit 331223 is configured to collect the electrical signals of the home power grid terminal 320 and the mains input terminal 310. The control unit 331224 is configured to determine whether there is power at the mains input terminal 310 and whether there is power at the home power grid terminal 320 according to the electrical signals, control the mechanical locking unit 3312252 to lock or unlock the mechanical transmission unit 3312251, or control the main circuit switch 33121 to close or open.

[0111] Specifically, the detection unit 331223 can collect the electrical signals of the home power grid terminal 320 and the mains input terminal 310, and thus send the sampled electrical signals to the control unit 331224, so that the control unit 331224 can determine whether there is power at the mains access terminal and whether there is power at the home power grid terminal 320 according to the electrical signals, and control the main circuit switch 33121 to close or open. Among them, the electrical signal can be a current signal or a voltage signal, which is not limited here.

[0112] In detail, please refer to Figure 9 and Figure 10 , when the detection unit 331223 samples that the current value at the mains input terminal 310 is not 0 or is a relatively large current value, and the home power grid is not connected to the energy storage device 200, the control unit 331224 can determine that there is power at the mains input terminal 310, that is, determine that the mains is normal. At this time, the main circuit switch 33121 can be controlled to close, so that the mains supplies power to the home power grid.

[0113] When the detection unit 331223 samples that the current value at the mains input terminal 310 is 0, and the home power grid is connected to the energy storage device 200, the control unit 331224 can determine that the mains input terminal 310 is not connected to the mains, that is, the mains is powered off. At this time, the main circuit switch 33121 can be controlled to open, so that the energy storage device 200 supplies power to the home power grid.

[0114] That is to say, the control module 33122 of the home power distribution device 100 of the present application can collect the electrical signals of the mains input terminal 310 and the home power grid terminal 320 in real time by setting the detection unit 331223, so that the control unit 331224 can determine whether there is power on both sides of the mains and the home power grid, and then make corresponding intelligent controls, which brings convenience to the user's life. At the same time, it can ensure the convenience and safety of the user during the process of using the energy storage device 200 for home emergency power supply, and can avoid abnormal situations such as short circuits in the circuit formed by the energy storage device 200 and the mains, and ensure the safety of the user using the energy storage device 200 for emergency power supply.

[0115] Thus, when the power supply of the mains power fails and the energy storage device 200 provides alternating current to the home power grid instantaneously or within a preset time, the mechanical locking unit 3312252 can be locked by the control unit 331224 to control the mechanical transmission unit 3312251 of the home power distribution device 100 of the present application, which can prevent circuit failures when the energy storage device 200 supplies power to the home power grid and ensure the circuit safety when the energy storage device 200 supplies power.

[0116] In some embodiments, the control module 33122 is communicatively connected to the energy storage device 200. When the power supply of the mains power fails and the main circuit switch 33121 is turned off, the control module 33122 controls the energy storage device 200 to supply power to the home power grid.

[0117] That is to say, the control module 33122 can detect in real time whether the energy storage device 200 is connected to the home power grid. When the energy storage device 200 is connected to the home power grid, the control module 33122 can establish a communication connection with the connected energy storage device 200.

[0118] Thus, in the case where the power supply of the mains power fails and the main circuit switch 33121 is turned off, the control module 33122 can establish a communication connection with the energy storage device 200 connected to the home power grid. For example, a wireless communication signal can be sent to the energy storage device 200 to trigger the control of the energy storage device 200 to turn on the AC output function to output alternating current, realizing the intelligent control of the control module 33122 to use the energy storage device 200 to supply emergency power to the home power grid.

[0119] Please refer to Figure 11 , in some embodiments, the control module 33122 and the energy storage device 200 are respectively communicatively connected to the same mobile terminal 400, and the energy storage device 200 can establish a communication connection with the control module 33122 through the mobile terminal 400. The control module 33122 is used to control the power supply situation between the energy storage device 200 and the home power grid, and transmit the power supply situation through communication to the mobile terminal 400 for display on the mobile terminal 400.

[0120] Specifically, for example, the control module 33122 can be bound and communicatively connected to an application program on the mobile terminal 400 regarding home electricity consumption. If the energy storage device 200 supports a wireless communication function, the energy storage device 200 can also be bound to the control module 33122 through the application program on the mobile terminal 400 regarding home electricity consumption. When the bound energy storage device 200 is in the powered-on state, it can communicate with the control module 33122 through the wireless communication function.

[0121] After the control module 33122, the energy storage device 200, and the mobile terminal 400 establish a mutual communication relationship, the control module 33122 can control the energy storage device 200 to turn on the AC output function to output alternating current when detecting a power outage of the mains. In addition, the control module 33122 can also transmit the power supply situation of the energy storage device 200 turning on the AC output function to output alternating current to the home power grid to the application program for home electricity use on the mobile terminal 400 through communication, and can display the power supply situation on the application program of the mobile terminal 400. Among them, the power supply situation may include information such as the electrical connection situation between the energy storage device 200 and the home power grid, the power supply duration, etc.

[0122] For example, the application program of the mobile terminal 400 can display the electrical connection situation between the energy storage device 200 and the home power grid. If the electrical connection between the energy storage device 200 and the home power grid is normal and the energy storage device 200 can supply power to the home power grid normally, the application program will display the state of normal connection between the two. If the electrical connection between the energy storage device 200 and the home power grid is disconnected and the energy storage device 200 stops supplying power to the home power grid, the application program will display the state of disconnection between the two.

[0123] In this way, it is convenient for users to know the power supply situation of the energy storage device 200 to the home power grid in real time through the mobile terminal 400.

[0124] In some embodiments, the control module 33122 is also used to receive user control instructions issued by the mobile terminal 400 and control the connection situation between the energy storage device 200 and the home power grid according to the user control instructions.

[0125] Specifically, the user control instructions may include, for example, a switch control instruction for the energy storage device 200, a control instruction for adjusting the output power supply of the energy storage device 200, a switch control instruction for the control module 33122, or other control instructions, which are not limited here.

[0126] It can be understood that since the control module 33122, the energy storage device 200, and the mobile terminal 400 establish a mutual communication relationship, not only can the control module 33122 and the energy storage device 200 transmit information to the mobile terminal 400 and display it on the application program of the mobile terminal 400, but similarly, users can also perform operations such as remote switch control of the energy storage device 200 and remote control of the control module 33122 on the application program for home electricity use on the mobile terminal 400, which is more convenient, fast, and intelligent.

[0127] In this way, in the present application, the energy storage device 200 with wireless communication function and the control module 33122 are bound through the same mobile terminal 400 to establish a local area network, enabling the user to remotely control the operations of the energy storage device 200 and the control module 33122 through the network on the mobile terminal 400, which is convenient for the user to use and manage and makes the control more intelligent.

[0128] In some embodiments, when the energy storage device 200 is in the powered-on state, the control module 33122 is used to read the energy storage information of the energy storage device 200 and display the energy storage information on the mobile terminal 400.

[0129] Specifically, the energy storage information includes information such as the model, power supply power, and remaining capacity of the energy storage device 200.

[0130] In this way, in the present application, the energy storage device 200 with wireless communication function and the control module 33122 are bound through the same mobile terminal 400 to establish a local area network. The control module 33122 can automatically read the energy storage information of the energy storage device 200, transmit the energy storage information to the mobile terminal 400 and display it on the mobile terminal 400, facilitating the user to view the energy storage information of the energy storage device 200 in real time through the mobile terminal 400.

[0131] Please refer to Figure 10 and Figure 11 , in some embodiments, the control module 33122 includes a first communication unit 331226. The energy storage device 200 includes a second communication unit 210. The first communication unit 331226 and the second communication unit 210 are respectively communicatively connected to the mobile terminal 400. The second communication unit 210 can establish a communication connection with the first communication unit 331226 through the mobile terminal 400.

[0132] That is to say, the control module 33122 of the present application can have a wired communication function or a wireless communication function, and is provided with a first communication unit 331226, and the first communication unit 331226 can include an Internet of Things card, etc. The energy storage device 200 connected to the household power distribution device 100 can also have a wired communication function or a wireless communication function, and is provided with a second communication unit 210, and the second communication unit 210 can also include an Internet of Things card, etc. The first communication unit 331226 and the second communication unit 210 can be mutually bound through the mobile terminal 400 to establish a wireless communication relationship, realizing the remote intelligent control of the access and disconnection of the energy storage device 200 and the household power grid by the control module 33122 through the mobile terminal 400, making it more intelligent.

[0133] In addition, it can be understood that if the energy storage device 200 selected by the user does not have a wireless communication function, the energy storage device 200 cannot be bound to the control module 33122. Then, the access action and disconnection action of the energy storage device 200 can be manually operated by the user, so that the energy storage device 200 without a wireless communication function can also have the function of home emergency power supply.

[0134] In some embodiments, the control module 33122 is further configured to, during the process of the energy storage device 200 supplying power to the home power grid, when detecting the power-on of the mains power, issue a prompt for the power-on of the mains power.

[0135] Specifically, during the process of the energy storage device 200 supplying power to the home power grid, if the mains power comes on, and the control module 33122 detects the message of the power-on of the mains power, it can prompt the user of the message of the power-on of the mains power through the notification method preset by the user. For example, specifically, it can remind the user of the power-on of the mains power by means of sound and light reminder, or by pushing the application program information to the mobile terminal 400 that is wirelessly communicated with the control module 33122.

[0136] When the user receives the prompt for the power-on of the mains power issued by the control module 33122, the user can manually turn off the AC output function of the energy storage device 200, and then manually close the main circuit switch 33121 to restore the mains power supply.

[0137] When the control module 33122 and the energy storage device 200 are bound to the same mobile terminal 400 to establish a local area network, when the user receives the prompt for the power-on of the mains power, the user can also remotely turn off the AC output function of the energy storage device 200 through the application program on the mobile terminal 400, and then set the control module 33122 to close the main circuit switch 33121 or manually close the main circuit switch 33121 through the mobile terminal 400 to restore the mains power supply.

[0138] In an example, if the prompt issued by the control module 33122 is a voice prompt, the voice prompt can be "The mains power has come on. Please turn off the AC output function of the energy storage device 200 in time and then close the main circuit switch!"

[0139] It can be understood that if the AC output function of the energy storage device 200 is not turned off first to disconnect the electrical connection relationship between the energy storage device 200 and the home power grid, the main circuit switch 33121 cannot be unlocked and closed. Therefore, the control module 33122 of the present application, during the process of the energy storage device 200 supplying power to the home power grid, when detecting the power-on of the mains power, issues a prompt for the power-on of the mains power, which can remind the user to turn off the AC output function of the energy storage device 200 in time so as to unlock and close the main circuit switch 33121, ensuring the normal operation of the circuit inside the home power distribution device 100.

[0140] Thus, during the process of the energy storage device 200 supplying power to the home power grid, when the control module 33122 of the home power distribution device 100 of the present application detects the incoming power of the main power supply, a prompt for the incoming power of the main power supply can be sent, facilitating the user to timely turn off the AC output function of the energy storage device 200 so as to unlock and close the main circuit switch 33121, ensuring the normal operation of the circuit inside the home power distribution device 100.

[0141] In some embodiments, the control module 33122 is further configured to adjust the voltage range that can be received by the home power grid terminal 320, so that the output voltage of the energy storage device 200 matches the input voltage of the home power grid terminal 320.

[0142] It can be understood that since the required ranges of household alternating current are different for different countries, correspondingly, when the energy storage device 200 is used for emergency power supply, the corresponding output voltages of the energy storage device 200 are also different. Therefore, it is necessary to make the output voltage of the energy storage device 200 match the voltage applied in the home in order to enable the energy storage device 200 to normally enter the working state and supply power to the home power grid.

[0143] The present application further provides a home power supply network. The home power supply network includes an energy storage device 200, a home power distribution device 300, and the intelligent control socket 100 described in any one of the above embodiments. The intelligent control socket 100 is connected in series between the main circuit switch 33121 of the home power distribution device 300 and the branch circuit switch 3321 of the home power distribution device 300, or the intelligent control socket 100 is connected in series between the branch circuit switch of the home power distribution device 300 and a preset number of ordinary sockets in the home power distribution device 300. The energy storage device 200 can be connected to the home power grid through the intelligent control socket 100 and supply power to the home power grid in the case of a power outage of the main power supply.

[0144] Thus, in the home power supply network of the present application, the intelligent control socket 100 can be connected to the main power supply, the energy storage device 200, and the home load respectively. A changeover switch 10 is provided inside the intelligent control socket 100 to realize the switching and loading between the main power supply and the energy storage device 200, and the risk of electric shock and grid connection risk when the main power supply and the energy storage device 200 are simultaneously connected to the home power grid can be avoided.

[0145] The above embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but should not be construed as limiting the patent scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
