Description
Technical Field
[0001] This application relates to the technical field of home power distribution, and particularly to a home power distribution device and a home power supply network. Background Art
[0002] At present, there are more and more suppliers of portable energy storage devices on the market, and at the same time, the power of the products is getting larger and larger. Simply using them for outdoor power supply functions may result in too low usage frequency and high cost, which is not cost-effective.
[0003] In addition, if a portable energy storage device is used for home power consumption or emergency power consumption, since a conventional portable energy storage device only has an off-grid output function, when directly connected to a home power grid, when the mains power and the portable energy storage device output simultaneously, the alternating currents of the two will damage household appliances due to the phase difference problem. The conventional method is to additionally match and install a corresponding secondary distribution box for the portable energy storage device. That is, the home power grid is configured with a main distribution box and a secondary distribution box at the same time. The main distribution box is connected to the mains power to supply power to non-critical loads in the home, and the secondary distribution box can be connected to the mains power and the portable energy storage device at the same time to supply power to critical loads. The secondary distribution box only supplies power from the mains power or the portable energy storage device at the same time to avoid damage to household appliances due to phase difference. This method makes the entire home power grid bloated, increases the usage cost of consumers, and at the same time, the portable energy storage device is limited to use at the location of the secondary distribution box, which is inconvenient.

[0033] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as limiting the present application.
[0034] Please refer to Figure 1 , the present application provides a household power distribution device 100. The household power distribution device 100 includes a mains input end 10, a household power grid end 20, and a power distribution management module 30.
[0035] The mains input end 10 is used to connect to the mains power. The household power grid end 20 is used to connect to the household power grid. The household power grid can be connected to either the mains power or an energy storage device 200.
[0036] The power distribution management module 30 includes an output main path 31. The output main path 31 includes a main path switch 311 and a control module 312. The main path switch 311 is electrically connected to the control module 312. One end of the main path switch 311 is connected to the mains input end 10, and the other end of the main path switch 311 is connected to the household power grid end 20.
[0037] The control module 312 includes a detection unit 3121. The detection unit 3121 is used to detect whether the mains input end 10 loses power and to detect whether the energy storage device 200 is connected to the household power grid. The control module 312 is used to control the main path switch 311 to disconnect when the detection unit 3121 detects that the mains input end 10 loses power, so that the energy storage device 200 supplies power to the household power grid; and the control module 312 is used to control the main path switch 311 to close when there is mains power 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.
[0038] Specifically, as Figure 2As shown, the detection unit 3121 can be directly electrically connected to the household power grid terminal 20 and the mains power input terminal 10 respectively, so as to detect whether the mains power is cut off and whether the energy storage device 200 is connected to the household power grid. For example, if the detection unit 3121 detects that there is power at the mains power input terminal 10, it means that the mains power has not been cut off, that is, the mains power is normal. If the detection unit 3121 detects that the mains power input terminal 10 has no power, it means that the mains power has been cut off. If the detection unit 3121 detects that the mains power is cut off and there is power at the household power grid terminal 20, it means that the energy storage device 200 has been connected to the household power grid. If the detection unit 3121 detects that the mains power is cut off and there is no power at the household power grid terminal 20, it means that the energy storage device 200 has not been connected to the household power grid.
[0039] In this way, in this application, by setting the detection unit 3121 in the control module 312, it can be detected whether the mains power connected to the household power grid is cut off and whether the household power grid is connected with the energy storage device 200.
[0040] Among them, the main circuit switch 311 can be a circuit breaker. One end of the main circuit switch 311 is connected to the mains power input terminal 10, and the other end of the main circuit switch 311 is connected to the household power grid terminal 20. The control module 312 is used to control the main circuit switch 311 to close when the mains power is normal and the household power grid is not connected with the energy storage device 200, so that the mains power supplies power to the household power grid. That is to say, the main circuit switch 311 can control the on-off of the path between the mains power and the household power grid. When the main circuit switch 311 is closed, the mains power is electrically connected to the household power grid, and the household power grid is powered by the mains power. When the main circuit switch 311 is opened, the connection between the mains power and the household power grid is disconnected, and the household power grid cannot be powered by the mains power at this time.
[0041] The control module 312 is used to control the main circuit switch 311 to open when the detection unit 3131 detects that the mains power input terminal 10 has no power, so that the energy storage device 200 supplies power to the household power grid. That is to say, when the mains power is cut off, the control module 312 can automatically control the main circuit switch 311 to open, so that the connection between the mains power and the household power grid is disconnected, that is, when the household power grid cannot be powered by the mains power at this time, the control module 312 can switch to supply power to the household power grid by the energy storage device 200.
[0042] That is to say, the household power distribution device 100 of this application can supply power to the household power grid at the household power grid terminal 20 through the mains power connected through the mains power input terminal 10 when the mains power is normal. In addition, when the mains power is cut off, the household power distribution device 100 of this application can be intelligently switched by the control module 312 to control the energy storage device 200 to supply emergency power to the household power grid.
[0043] Thus, the home power distribution device 100 of the present application can expand the application functions of the energy storage device 200, so that the energy storage device 200 not only meets the power supply for outdoor activities, but also can be used as emergency power supply when the home power grid is powered off. In addition, by adding a control module 312 to the power distribution management module 30, the home power distribution device 100 of the present application can intelligently control the main circuit switch 311 to disconnect in the case of power failure of the commercial power, so that the energy storage device 200 connected to the energy storage access end 30 supplies emergency power to the home power grid, without the need to additionally match and install a corresponding distribution box for the energy storage device 200, realizing the simple and quick addition of the energy storage device 200 to the home emergency power supply.
[0044] Please refer to Figure 2 , in some embodiments, the control module 312 further includes a control unit 3122 and a driving unit 3123. The control unit 3122 is respectively connected to the detection unit 3121 and the driving unit 3123, and the driving unit 3123 is connected to the main circuit switch 311. The control unit 3122 is configured to control the driving unit 3123 to act to disconnect the main circuit switch 311 and control the energy storage device 200 to supply power to the home power grid when the detection unit 3121 detects a power failure at the commercial power input end 10 and there is an energy storage device 200 connected to the home power grid.
[0045] Specifically, the driving unit 3123 can be a motor or other driving devices, which is not limited herein.
[0046] When the commercial power is powered off, as long as the detection unit 3121 detects the power failure of the commercial power, it can control the driving unit 3123 to drive the main circuit switch 311 to disconnect, so that the connection between the home power grid and the commercial power is disconnected, making the home power grid 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 for the energy storage device 200 to be connected to the home power grid can be to insert the energy storage device 200 into any socket used in the home, so as to be connected 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 a socket in any room of the home, so as to supply alternating current to the whole home. Among them, the socket can be a special socket set for power supply connection of the energy storage device 200.
[0047] For example, as Figure 1 shown, the energy storage device 200 can be connected to a socket in the living room, or can also be connected to a socket 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.
[0048] Thus, when the power detection unit 3121 detects a power outage at the mains input terminal 10 and there is an energy storage device 200 connected to the home power grid, the control unit 3122 controls the driving unit 3123 to operate to disconnect the main switch 311, and controls the energy storage device 200 to supply power to the home power grid. That is, the control module 312 composed of the control unit 3122, the detection unit 3121, and the driving unit 3123 can realize the switching of the power supply source of the home power grid.
[0049] Please refer to Figure 2 , in some embodiments, the driving unit 3123 further includes a mechanical transmission unit 31231 and a mechanical locking unit 31232. The mechanical locking unit 31232 is connected to the mechanical transmission unit 31231, and the mechanical transmission unit 31231 and the mechanical locking unit 31232 are connected to the control unit 3122. The control unit 3122 is further configured to control the mechanical transmission unit 31231 to operate to disconnect the main switch 311 when the mains input terminal 10 loses power, and to control the mechanical locking unit 31232 to lock the mechanical transmission unit 31231 within a preset time after the energy storage device 200 starts to supply power to the home power grid, so as to keep the main switch 311 in the off state.
[0050] Specifically, the mechanical transmission unit 31231 can be a transmission shaft. Correspondingly, the control module 312 further includes a transmission shaft control circuit in which the control unit 3122 is connected to the transmission shaft. When a power outage occurs in the mains, as long as the detection unit 3121 detects the power outage, it can control the transmission shaft to rotate through the transmission shaft control circuit, thereby controlling the main switch 311 to disconnect, so that the connection between the home power grid and the mains is disconnected, and the home power grid becomes an independent module.
[0051] 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, and is not limited herein. When the preset time is 0S, the control unit 3122 can control the mechanical locking unit 31232 to lock the mechanical transmission unit 31231 simultaneously after the mains input terminal 10 loses power and the energy storage device 200 starts to supply power to the home power grid, so as to keep the main switch 311 in the off state. When the preset time is 0.1S, the control unit 3122 can control the mechanical locking unit 31232 to lock the mechanical transmission unit 31231 within 0.1S after the mains loses power and the energy storage device 200 starts to supply power to the home power grid, so as to keep the main switch 311 in the off state.
[0052] Understandably, 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 a preset time, the control unit 3122 controls the mechanical locking unit 31232 to lock the mechanical transmission unit 31231, and the mechanical transmission unit 31231 can be locked in the rotation state when the main circuit switch 311 is in the off state, preventing the user from accidentally touching the main circuit switch 311 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 malfunction of the energy storage device 200 and causing an electrical hazard.
[0053] Specifically, when the main circuit switch 311 is off and the energy storage device 200 supplies power to the home power grid, the detection unit 3121 can simultaneously collect the current values of the mains power input end 10 and the home power grid end 20, and the control unit 3122 determines whether there is power on both sides of the mains power input end 10 and the home power grid end 20 according to the current values.
[0054] If the current value sampled by the detection unit 3121 at the mains power input end 10 is 0, and when the current value sampled by the detection unit 3121 at the home power grid end 20 is not 0 or is a relatively large current value, the control unit 3122 can determine that there is no power at the mains power input end 10 at this time, the mains power is still in the power-off state, and there is power at the home power grid end 20. Therefore, the control unit 3122 can control the mechanical locking unit 31232 to lock the mechanical transmission unit 31231 to keep the main circuit switch 311 in the off state, and record that the home power distribution device 100 is in the energy storage emergency power supply state at this time.
[0055] If the current value sampled by the detection unit 3121 at the mains power input end 10 is not 0 or is a relatively large current value, and when the current value sampled by the detection unit 3121 at the home power grid end 20 is not 0 or is a relatively large current value, the control unit 3122 can determine that there is power at the mains power input end 10 at this time, the mains power is in the power-on state, and there is power at the home power grid end 20. Therefore, the control unit 3122 can control the mechanical locking unit 31232 to lock the mechanical transmission unit 31231 to keep the main circuit switch 311 in the off state, and remind the user that the mains power is on, so as to facilitate the user to timely turn off the alternating current output function of the energy storage device 200 or disconnect the energy storage device 200 from the energy storage access end 30, and then manually or through the application program (APP) on the mobile terminal 300 to operate to turn off the main circuit switch 311 and restore the mains power to supply power to the home power grid.
[0056] If the current value sampled by the detection unit 3121 at the mains input end 10 is not 0 or is a relatively large current value, and when the current value sampled by the detection unit 3121 at the household power grid end 20 is 0, the control unit 3122 can determine that there is power at the mains input end 10 at this time, the mains is in a power-on state, and there is no power at the household power grid end 20, indicating that the energy storage device 200 has turned off the AC output function or has disconnected the energy storage device 200 from the household power grid, and the energy storage device 200 stops supplying power to the household power grid. Therefore, at this time, the control unit 3122 can directly control the main circuit switch 311 to close, and restore the mains to supply power to the household power grid again.
[0057] Please refer to Figure 2 and Figure 3 , the control unit 3122 is electrically connected to the first end of the detection unit 3121. The second end of the detection unit 3121 is electrically connected to the household power grid end 20, and the third end of the detection unit 3121 is electrically connected to the mains input end 10. The detection unit 3121 is used to collect the electrical signals of the household power grid end 20 and the mains input end 10. The control unit 3122 is used to determine whether there is power at the mains access end 10 and whether there is power at the household power grid end 20 according to the electrical signals, control the mechanical locking unit 31232 to lock or unlock the mechanical transmission unit 31231, or control the main circuit switch 311 to close or open.
[0058] Specifically, the detection unit 3121 can collect the electrical signals of the household power grid end 20 and the mains input end 10, and thus send the sampled electrical signals to the control unit 3122, so that the control unit 3122 can determine whether there is power at the mains access end according to the electrical signals, and determine whether there is power at the household power grid end 20, and control the main circuit switch 311 to close or open. Among them, the electrical signal can be a current signal or a voltage signal, which is not limited here.
[0059] In detail, please refer to Figure 2 and Figure 3 , when the current value sampled by the detection unit 3121 at the mains input end 10 is not 0 or is a relatively large current value, and the household power grid is not connected to the energy storage device 200, the control unit 3122 can determine that there is power at the mains access end 10, that is, determine that the mains is normal. At this time, the main circuit switch 311 can be controlled to close, so that the mains supplies power to the household power grid.
[0060] When the current value sampled by the detection unit 3121 at the mains input end 10 is 0, and there is an energy storage device 200 connected to the household power grid, the control unit 3122 can determine that the mains input end 10 is not connected to the mains, that is, the mains has lost power. At this time, the main circuit switch 311 can be controlled to open, so that the energy storage device 200 supplies power to the household power grid.
[0061] That is to say, the control module 312 of the home power distribution device 100 of the present application can collect the electrical signals of the mains access end 10 and the home power grid end 20 in real time by setting the detection unit 3121, enabling the control unit 3122 to determine whether there is electricity on both sides of the mains and the home power grid, and then making corresponding intelligent controls, which brings convenience to users' lives. At the same time, it can ensure the convenience and safety of users during the process of using the energy storage device 200 for home emergency power supply, and can avoid abnormal situations that may cause the circuit formed by the energy storage device 200 and the mains to short-circuit, ensuring the safety of users applying the energy storage device 200 for emergency power supply.
[0062] In this way, the home power distribution device 100 of the present application can, at the moment or within a preset time when the mains power is cut off and the energy storage device 200 provides alternating current for the home power grid, control the mechanical locking unit 31232 to lock the mechanical transmission unit 31231 through the control unit 3122, 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.
[0063] Please refer to Figure 2 , in some embodiments, the control module 312 is electrically connected to the home power grid end 20 and the mains access end 10 respectively.
[0064] Specifically, as Figure 2 shown, a switching power supply can be provided inside the control module 312. When there is electricity at either the mains access end 10 or the home power grid end 20, it can automatically supply electrical energy to the switching power supply, enabling the switching power supply to start working, and realizing that either the mains or the home power grid can provide the electrical energy required for the internal circuit of the control module 312.
[0065] That is to say, in the case where the mains is normal and the energy storage device 200 is not connected to the home power grid end, the control module 312 of the present application can maintain normal operation through the electrical energy provided by the mains accessed through the mains access end 10, thereby controlling the main circuit switch 311 to remain closed. In the case where the mains power is cut off and the energy storage device 200 is connected to the home power grid end, the control module 312 of the present application can maintain normal operation through the electrical energy provided by the energy storage device 200 accessed through the home power grid end 20, thereby controlling the main circuit switch 311 to remain open, which can avoid the power supply circuits of the mains and the energy storage device 200 at the home power grid end being combined together when the mains power comes back, generating a grid connection risk.
[0066] In some embodiments, the control module 312 further includes a backup power supply. One end of the backup power supply is connected to the mains input end 10, and the other end of the backup power supply is connected to the switching power supply. The backup power supply is used to be charged through the mains when the mains is normal, and is used to supply electrical energy to the switching power supply when the mains power is cut off to drive the main circuit switch 311 to open.
[0067] Specifically, the backup power supply is arranged between the mains input terminal 10 and the switching power supply. When the mains power exists, the mains power can charge the backup power supply, and at the same time, the mains power can also supply power to the switching power supply, and the switching power supply drives and controls the main circuit switch 311 to close. When the mains power fails, if the main circuit switch 311 is in the closed state, the electrical energy provided by the backup power supply can be used for the switching power supply, so that the switching power supply drives and controls the main circuit switch 311 to disconnect, realizing the self-recovery disconnection function of the main circuit switch 311.
[0068] After that, after the main circuit switch 311 is controlled to disconnect by the electrical energy provided by the backup power supply 3122, at this time, if the energy storage device 200 is connected to the household power grid, the AC output function of the energy storage device 200 can be turned on, and through a socket in any room of the household power grid, for example, the energy storage device 200 is connected to a socket in the living room, or it can also be connected to a socket in other rooms. The connection position is determined freely according to the convenience of the user or the power consumption, and the alternating current of the energy storage device 200 is provided to the household power grid to supply alternating current to the whole family.
[0069] Among them, the backup power supply includes a battery module or a capacitor module. That is to say, the backup power supply of the present application can use rechargeable batteries such as lithium batteries as energy storage elements, or can use supercapacitors such as electric double layer capacitors as energy storage elements to pre-store the electrical energy required to drive and control the main circuit switch 311 to disconnect.
[0070] In some embodiments, the control module 312 is communicatively connected to the energy storage device 200.
[0071] That is to say, the control module 312 can detect in real time whether the energy storage device 200 is connected to the household power grid, and when the energy storage device 200 is connected to the household power grid, the control module 312 can establish a communication connection with the connected energy storage device 200.
[0072] In this way, in the case where the mains power failure is detected in the present application, the control module 312 can establish a communication connection with the energy storage device 200 connected to the household 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 312 to use the energy storage device 200 to supply emergency power to the household power grid.
[0073] Please refer to Figure 4 , in some embodiments, the control module 312 and the energy storage device 200 are respectively communicatively connected to the same mobile terminal 300, and the energy storage device 200 can establish a communication connection with the control module 312 through the mobile terminal 300. The control module 312 is used to control the power supply situation between the energy storage device 200 and the household power grid, and transmit the power supply situation to the mobile terminal 300 through communication for display on the mobile terminal 300.
[0074] Specifically, for example, the control module 312 can be bound to communicate with an application program on the mobile terminal 300 regarding household electricity. If the energy storage device 200 supports wireless communication functions, the energy storage device 200 can also be bound to the control module 312 through the application program on the mobile terminal 300 regarding household electricity. When the bound energy storage device 200 is in the powered-on state, it can communicate with the control module 312 through the wireless communication function.
[0075] After the control module 312, the energy storage device 200, and the mobile terminal 300 establish a mutual communication relationship, when the control module 312 detects a power outage of the mains power, it can control the energy storage device 200 to turn on the AC output function to output alternating current. In addition, the control module 312 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 household power grid to the application program on the mobile terminal 300 through communication, and can display the power supply situation on the application program of the mobile terminal 300. Among them, the power supply situation can include information such as the electrical connection situation between the energy storage device 200 and the household power grid, the power supply duration, etc.
[0076] For example, the application program of the mobile terminal 300 can display the electrical connection situation between the energy storage device 200 and the household power grid. If the electrical connection between the energy storage device 200 and the household power grid is normal, the energy storage device 200 can normally supply power to the household power grid, then the normal connection state of the two is displayed on the application program. If the electrical connection between the energy storage device 200 and the household power grid is disconnected and the energy storage device 200 stops supplying power to the household power grid, then the disconnected state of the two is displayed on the application program.
[0077] In this way, it is convenient for the user to know in real time the power supply situation of the energy storage device 200 to the household power grid through the mobile terminal 300.
[0078] In some embodiments, the control module 312 is further configured to receive a user control instruction sent by the mobile terminal 300 and control the connection situation between the energy storage device and the household power grid end according to the user control instruction.
[0079] Specifically, the user control instruction can 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 312, or other control instructions, which are not limited here.
[0080] Understandably, since the control module 312, the energy storage device 200, and the mobile terminal 300 establish a mutual communication relationship, not only can the control module 312 and the energy storage device 200 transmit information to the mobile terminal 300 and display it on the application of the mobile terminal 300, but similarly, the user can also perform operations such as remotely turning on and off the energy storage device 200 and remotely controlling the control module 312 on the application of the mobile terminal 300 regarding household electricity use, which is more convenient, fast, and intelligent.
[0081] In this way, the present application binds the energy storage device 200 with wireless communication function and the control module 312 through the same mobile terminal 300 to establish a local area network, realizing the operation that the user remotely controls the energy storage device 200 and the control module 312 through the network on the mobile terminal 300, which is convenient for the user to use and manage, and the control is more intelligent.
[0082] In some embodiments, when the energy storage device 200 is in the on state, the control module 312 is configured to read the energy storage information of the energy storage device 200 and display the energy storage information on the mobile terminal 300.
[0083] Specifically, the energy storage information includes information such as the model, power supply power, and remaining capacity of the energy storage device 200.
[0084] In this way, the present application binds the energy storage device 200 with wireless communication function and the control module 312 through the same mobile terminal 300 to establish a local area network. The control module 312 can automatically read the energy storage information of the energy storage device 200, transmit the energy storage information to the mobile terminal 300 and display it on the mobile terminal 300, facilitating the user to view the energy storage information of the energy storage device 200 in real time through the mobile terminal 300.
[0085] Please refer to Figure 2 and Figure 4 , in some embodiments, the control module 312 includes a first communication unit 3124, the energy storage device 200 includes a second communication unit 210, and the first communication unit 3124 and the second communication unit 210 are respectively communicatively connected to the mobile terminal 300. The second communication unit 210 can establish a communication connection with the first communication unit 3124 through the mobile terminal 300.
[0086] That is, the control module 312 of the present application can have a wired communication function or a wireless communication function, and is provided with a first communication unit 3124. The first communication unit 3124 can include an Internet of Things card or the like. 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. The second communication unit 210 can also include an Internet of Things card or the like. The first communication unit 3124 and the second communication unit 210 can be mutually bound through the mobile terminal 300 to establish a wireless communication relationship, so as to realize the remote intelligent control of the access and disconnection of the energy storage device 200 and the household power grid by the control module 312 through the mobile terminal 300, which is more intelligent.
[0087] In addition, it can be understood that if the selected energy storage device 200 does not have a wireless communication function, the energy storage device 200 cannot be bound to the control module 312. 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 household emergency power supply function.
[0088] In some embodiments, the control module 312 is further configured to, during the process of the energy storage device 200 supplying power to the household power grid, when detecting the power-on of the commercial power, issue a prompt for the power-on of the commercial power.
[0089] Specifically, during the process of the energy storage device 200 supplying power to the household power grid, if the commercial power comes on, and the control module 312 detects the message of the power-on of the commercial power, it can prompt the user of the message of the power-on of the commercial power through the notification method preset by the user. For example, specifically, it can remind the user of the power-on of the commercial power by means of sound and light reminder, or by pushing the application program information to the mobile terminal 300 wirelessly communicating with the control module 312 to remind the user of the power-on of the commercial power.
[0090] When the user receives the prompt for the power-on of the commercial power issued by the control module 312, the user can manually turn off the AC output function of the energy storage device 200, and then manually close the main circuit switch 311 to restore the commercial power supply.
[0091] When the control module 312 and the energy storage device 200 are bound to the same mobile terminal 300 to establish a local area network, when the user receives the prompt for the power-on of the commercial 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 300, and then set the control module 312 to close the main circuit switch 311 or manually close the main circuit switch 311 through the mobile terminal 300 to restore the commercial power supply.
[0092] In an example, if the prompt issued by the control module 312 is a voice prompt, the voice prompt can be "The commercial power has come on. Please turn off the AC output function of the energy storage device in time and then close the main circuit switch!"
[0093] Understandably, if the AC output function of the energy storage device 200 is not turned off first to disconnect the electrical connection between the energy storage device 200 and the household power grid, the main circuit switch 311 cannot be unlocked and closed. Therefore, when the control module 312 of the present application detects the incoming mains power during the process of the energy storage device 200 supplying power to the household power grid, it issues a prompt for the incoming mains power, which can remind the user to turn off the AC output function of the energy storage device 200 in time to unlock and close the main circuit switch 311, ensuring the normal operation of the circuit inside the household power distribution device 100.
[0094] In this way, the household power distribution device 100 of the present application can, through the control module 312, issue a prompt for the incoming mains power when detecting the incoming mains power during the process of the energy storage device 200 supplying power to the household power grid, facilitating the user to turn off the AC output function of the energy storage device 200 in time to unlock and close the main circuit switch 311, ensuring the normal operation of the circuit inside the household power distribution device 100.
[0095] Please refer to Figure 1 , in some embodiments, the power distribution management module 30 further includes a plurality of output branches 32. The output main path 31 is electrically connected to the plurality of output branches 32. The output branch 32 includes a power input end 321, a household load access end 322, and a branch switch 323. The power input end 321 is connected to the main circuit switch 311. The branch switch 323 is disposed between the power input end 321 and the household load access end 322 for controlling the on / off of the path between the power input end 321 and the household load access end 322. Among them, the branch switch 323 can be a circuit breaker.
[0096] Specifically, as Figure 1 shown, in the bathroom, room 1, room 2, living room, and kitchen in the user's home, there is a corresponding output branch 32. That is, each household area corresponds to a household load access end 322 in the power distribution management module 30 of the household power distribution device 100 for electrically connecting 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 switch 323.
[0097] For example, when the branch switch 323 corresponding to the bathroom is closed, the path between the power input end 321 where the bathroom is located and the household load access end 322 is conducted, and the household loads in the bathroom, such as lights and heaters, can be connected to the alternating current for normal operation. When the branch switch 323 corresponding to the bathroom is opened, the path between the power input end 321 where the bathroom is located and the household load access end 322 is disconnected, and at this time, the household loads in the bathroom, such as lights and heaters, cannot be connected to the alternating current and thus stop working.
[0098] In addition, when the energy storage device 200 is connected to the household power grid terminal 20 through a socket in the household area to supply power to 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 over-current capacity of the connected socket and the branch switch 323 on the branch where the socket is located.
[0099] In this way, in the household power distribution device 100 of the present application, the power distribution management module 30 can realize the power consumption control of the loads in different household areas by setting a plurality of output branches 32.
[0100] In some embodiments, the control module 312 is further configured to adjust the voltage range that the household power grid terminal 20 can receive, so that the output voltage of the energy storage device 200 matches the input voltage of the household power grid terminal 20.
[0101] It can be understood that since the required range of household alternating current is different for different countries, correspondingly, when the energy storage device 200 is used for emergency power supply, the corresponding output voltage of the energy storage device 200 is also different. Therefore, it is necessary to make the output voltage of the energy storage device 200 match the voltage applied to the household, so that the energy storage device 200 can normally enter the working state to supply power to the household power grid.
[0102] The household power distribution device 100 of the present application can adjust the voltage range that the household power grid terminal 20 can receive through the control module 312, which can enable the compatible access of the energy storage device 200 to different power grids globally, and realize the compatible application that all energy storage devices 200 with AC power supply can supply emergency power to the household, which is beneficial to the popularization and application of the energy storage device 200, and expands the application scenarios and usage ranges of the energy storage device 200.
[0103] The present application also provides a household power supply network. The household power supply network includes an energy storage device 200 and the household power distribution device 100 described in any one of the above embodiments. The energy storage device 200 can be connected to the household power grid and supply power to the household power grid in the case of a power outage of the mains.
[0104] In this way, in the household power supply network of the present application, the household power distribution device 100 can expand the application function of the energy storage device 200, so that the energy storage device 200 not only meets the power supply for outdoor activities, but also can be used as emergency power supply when the household power grid is powered off. In addition, by adding the control module 312 to the power distribution management module 30 in the household power distribution device 100 of the present application, in the case of a power outage of the mains, the main circuit switch 311 can be intelligently controlled to disconnect, so that the energy storage device 200 connected to the energy storage access end 30 supplies emergency power to the household power grid, and there is no need to additionally match and install a corresponding distribution box for the energy storage device 200, realizing the simple and quick addition of the energy storage device 200 to the household emergency power supply.
[0105] The above embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to 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 modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
