Description

[0001] Priority information This application claims priority and benefits to patent application No. 202510687469.5, filed with the China National Intellectual Property Administration on May 26, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of household power distribution technology, and in particular relates to a circuit breaker, a distribution box, and a household power distribution network. Background Technology

[0003] In a typical home electrical distribution network, the mains power is connected to the home distribution box, which then supplies power to the household loads through various branch circuits. A conventional home electrical distribution network can only be powered by the mains power; if the mains power fails, the entire household loses power.

[0004] To address the issue of household power outages due to mains power failures, existing solutions can incorporate backup energy storage power sources. There are two main approaches to connecting backup energy storage. First, equip core household loads with a smart distribution box or replace the traditional distribution box with a smart distribution box. The smart distribution box can connect to mains power or a backup energy storage power source, and internally can form multiple power supply branches to power household loads. When the mains power fails, it automatically switches to the backup energy storage power source. Second, connect an Automatic Transfer Switch (ATS) to the front end of the traditional distribution box. The ATS can connect to mains power or a backup energy storage power source and has the function of switching between mains power and backup energy storage power, but the power supply branches for household loads still need to be manually controlled through the traditional distribution box. After a mains power failure, the ATS can automatically switch to the backup energy storage power source.

[0005] In both of the above solutions, the distribution box or ATS is quite large, taking up a lot of space. Furthermore, these two types of electrical facilities are expensive to install and require professional electricians to drill holes and reconnect battery cells. Therefore, there is an urgent need for a flexible power distribution solution that can smoothly connect to a backup energy storage power source in the event of a mains power outage to ensure the normal operation of household loads, while reducing equipment size and installation costs. Utility Model Content

[0006] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a circuit breaker, a distribution box, and a household power distribution network. After a mains power outage, a backup power source supplies power to the circuit breaker, sending mains power failure and circuit breaker open status information to the energy storage device, so that the energy storage device's inverter output can supply power to the load.

[0007] In a first aspect, this application provides a circuit breaker for use in a home power distribution network, the home power distribution network including a first AC power source, an energy storage device, and multiple load branches, wherein the multiple load branches are connected in parallel, and at least one of the load branches is connected to the energy storage device, the circuit breaker comprising: A switch, wherein the first end of the switch is connected to a first AC power source, and the second end of the switch is connected to multiple load branches; A communication module, which communicates with the energy storage device; A detection module is connected to the first terminal of the switch. The detection module is used to detect whether the first terminal of the switch is de-energized and generate a first detection signal characterizing whether the first AC power supply is de-energized. The control module, connected to the detection module and the communication module, can control the closing of the switch; The power supply module supplies power to the detection module, the communication module, and the control module through the first AC power supply module; A backup power supply is provided to power the detection module, the communication module, and the control module in the event of a power failure of the first AC power supply. When the first AC power supply fails, the switch is opened, and the control module is used to send a first signal to the energy storage device through the communication module, so that the energy storage device provides a second AC power supply to the other load branches.

[0008] Secondly, this application provides a distribution box including the circuit breaker.

[0009] Thirdly, this application provides a home power distribution network, including the aforementioned distribution box, energy storage device, and multiple load branches.

[0010] This application provides a circuit breaker, a distribution box, and a home power distribution network. The circuit breaker includes a switch, a communication module, a detection module, a control module, a power supply module, and a backup power supply. In the event of a power outage of the first AC power source (such as mains power), the backup power supply can power the detection module, communication module, and control module through the power supply module. The detection module detects a power outage of the first AC power source connected to the first terminal of the switch, generates a first detection signal indicating the power outage, and transmits the first detection signal to the control module. The switch (normally open) automatically opens, or the switch (non-normally open) opens under the control of a motor driven by the controller of the control module. Subsequently, the control module transmits the first AC power outage information to the communication module, which then sends a first signal to an energy storage device. The energy storage device then inverts its output to provide a second AC power source to other load branches. In this process, the backup power supply achieves stable power outage detection of the first AC power source, thereby accurately controlling the inverter output of the energy storage device, achieving seamless power supply switching between mains power and the energy storage device, and increasing the safety and flexibility of the power supply system. The backup power supply provides power to the circuit breaker independently, reducing installation costs. Additional aspects and advantages of embodiments of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of embodiments of this application.

Detailed Implementation

[0012] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein 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 with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0013] This application provides a circuit breaker 100, which will be described in detail below: Please see Figure 1 and Figure 2 The circuit breaker 100 provided in this application embodiment is used in a home power distribution network 10. The home power distribution network 10 includes the circuit breaker 100, a first AC power supply 200, an energy storage device 300, and multiple load branches connected in parallel, with at least one load branch connected to the energy storage device 300. The circuit breaker 100 includes: Switch 101, the first terminal G1 of switch 101 is connected to the first AC power supply 200, and the second terminal G2 of switch 101 is connected to multiple load branches.

[0014] The first AC power source 200 can supply AC mains power from the power grid company or AC power output from a generator, and is the main source of electricity for household use. In addition to supplying power to the load and circuit breaker 100, the first AC power source 200 also charges the backup power source 106 of circuit breaker 100.

[0015] Specifically, the first terminal G1 of switch 101 is the node where circuit breaker 100 connects to the first AC power supply 200, i.e., the input terminal of circuit breaker 100, and is also the input point for a detectable signal indicating the state of the first AC power supply 200. The first terminal G1 of switch 101 is connected to power module 105 so that the first AC power supply 200 can supply power to circuit breaker 100.

[0016] Among them, the second terminal G2 of switch 101 is the node of the output terminal of circuit breaker 100, which is connected to the load branch of circuit breaker 100, and is also the input point of the detectable signal of the energy storage device 300 status.

[0017] Among them, the load branch refers to the power circuit connected to the output terminal of the circuit breaker 100, which may include lighting, sockets, home appliances, etc. It is usually a series of parallel branches equipped with circuit breaker 600 and wall socket 500. At least one load branch is connected to the energy storage device 300. When the first AC power supply 200 fails, the energy storage device 300 can provide a second AC power supply to other load branches to realize emergency power supply.

[0018] The energy storage device 300 refers to an energy storage power supply connected to the load branch that can output AC power through an inverter when the first AC power supply 200 fails, and can supply power to the load of its load branch. The energy storage device 300 can communicate with the communication module 102 of the circuit breaker 100 and receive signals from the control module 104 to determine whether to perform inverter output or disconnect the power supply.

[0019] This can be understood as follows: switch 101, as a direct actuator of circuit breaker 100, controls the connection and disconnection between the first AC power supply 200 and multiple load branches. The first terminal G1 of switch 101 is connected to the first AC power supply 200, and the second terminal G2 of switch 101 is connected to the load branches. Switch 101 can be opened or closed under the automatic control of control module 104 of circuit breaker 100, realizing safe isolation between the first AC power supply 200 and the load, and ensuring normal system operation.

[0020] Communication module 102 communicates with energy storage device 300.

[0021] Specifically, the communication module 102 receives instructions from the control module 104 and engages in bidirectional data communication with the energy storage device 300 via wired or wireless communication. The instructions received by the communication module 102 from the control module 104 include the status information of the first AC power supply 200. This information is sent to the energy storage device 300, which can trigger the inverter output of the energy storage device 300 or disconnect the power supply. Status information such as the power level of the energy storage device 300 can also be transmitted to the communication module 102, which then transmits it to the control module 104. Based on the feedback information from the energy storage device 300, the control module 104 decides whether to switch the power supply by controlling the on / off state of the control switch 101.

[0022] The detection module 103 is connected to the control module 104 and the first terminal G1 of the switch 101 respectively. The detection module 103 is used to detect whether the first terminal G1 of the switch 101 is de-energized and generate a first detection signal characterizing whether the first AC power supply 200 is de-energized.

[0023] The first detection signal is a logic signal generated by the detection module 103 when it detects at the first terminal G1 of the switch 101, which can be recognized by the control module 104 and reflects the state of the first AC power supply 200 (energized or de-energized).

[0024] Specifically, the detection module 103 continuously monitors the input signal at the first terminal G1 of the switch 101. The input signal includes original electrical parameters (such as voltage and waveform) representing the state of the first AC power supply 200. After sampling, signal processing, and comparison with a preset normal operating threshold, the input signal can generate a logic signal containing the state information of the first AC power supply 200, namely the first detection signal.

[0025] The control module 104 is connected to the detection module 103 and the communication module 102, and can control the closing of the switch 101.

[0026] The control module 104 includes a controller 1041 and a motor 1042. The controller 1041 controls the operation of the motor 1042, and the motor 1042 can drive the switch 101 to close or open.

[0027] Specifically, the controller 1041 of the control module 104 can determine the status of the first AC power supply 200 based on the first detection signal generated by the detection module 103: if the first AC power supply 200 is de-energized, the controller motor 1042 drives the switch 101 to open; if the first AC power supply 200 is normal, the controller keeps the switch 101 closed.

[0028] In some embodiments, after the communication module 102 is connected to the control module 104, it is connected to the detection module 103. After the detection module 103 sends the first detection signal to the control module 104, the control module 104 forwards it to the communication module 102.

[0029] It can be understood that the control module 104, as the command center of the circuit breaker 100, receives the first detection signal generated by the detection module 103, which contains the status information of the first AC power supply 200 (such as the mains power failure). On the other hand, after performing logical judgment on the first detection signal, it first controls the on / off state of the switch 101 (such as controlling the motor 1042 to drive the switch 101 to open), and then generates a control command to control the communication module 102 to send the status information of the first AC power supply 200 to the energy storage device 300, so as to control the access of the energy storage device 300 (such as starting the inverter output of the energy storage device 300).

[0030] The power module 105 supplies power to the detection module 103, communication module 102 and control module 104 through the first AC power supply 200.

[0031] Under normal operating conditions, the power supply module 105 converts the high-voltage AC power (e.g., 220V) from the first AC power supply 200 into low-voltage DC power (e.g., 5V, 3.3V) to power the detection module 103, communication module 102, and control module 104 inside the circuit breaker 100. When the first AC power supply 200 fails, the power supply module 105 supplies power to the various modules of the circuit breaker 100 through other power sources besides the first AC power supply 200 (e.g., backup power supply 106).

[0032] The backup power supply 106 is used to supply power to the detection module 103, communication module 102 and control module 104 in the event of a power failure of the first AC power supply 200.

[0033] The backup power supply 106 includes a battery or capacitor. The battery or capacitor should have enough charge to support the circuit breaker 100 control module 104 motor 1042 drive switch 101 to disconnect in the event of a mains power failure, and to support bidirectional data communication between the communication module 102 and the energy storage device 300.

[0034] It is understood that the backup power supply 106 is generally a DC power supply. Therefore, in the event of a power outage of the first AC power supply 200 in the power grid, it can independently supply power to the detection module 103, the communication module 102, and the control module 104. The backup power supply 106 can at least ensure that the status detection of the first AC power supply 200, the disconnection of switch 101, and bidirectional data communication can still be completed after the first AC power supply 200 is powered off, thereby improving system reliability.

[0035] The circuit breaker 100 provided in this application, when the first AC power supply 200 fails, switches 101 open, and control module 104 is used to send a first signal to energy storage device 300 through communication module 102 so that energy storage device 300 provides a second AC power supply to other load branches.

[0036] The second AC power source refers to the power output from the inverter of the energy storage device 300, which is used to supply power to other branch loads of the energy storage device 300 when the first AC power source 200 fails.

[0037] There are two ways to generate the first signal. The first way is that after the detection module 103 determines that the first AC power supply 200 has lost power, the control module 104 sends a signal to the energy storage device 300 via the communication module 102. In this case, the first signal indicates that the first AC power supply 200 has lost power, and the energy storage device 300 needs to determine this based on the signal and provide power from the second AC power supply. The second way is that the control module 104 directly sends a first signal requiring the energy storage device 300 to start, and the energy storage device 300 directly starts and provides power from the second AC power supply.

[0038] This application provides a circuit breaker 100, which includes a switch 101, a communication module 102, a detection module 103, a control module 104, a power module 105, and a backup power supply 106. In the event of a power outage of the first AC power supply 200 (e.g., mains power), the backup power supply 106 can supply power to the detection module 103, communication module 102, and control module 104 via the power module 105. The detection module 103 detects a power outage of the first AC power supply 200 connected to the first terminal G1 of the switch 101, generates a first detection signal indicating the power outage, and transmits the first detection signal to the control module 104. The switch 101 is opened under the control of the motor 1042 driven by the controller 1041 of the control module 104. Subsequently, the control module 104 transmits the first AC power supply 200 power outage information to the communication module 102, which then sends a first signal to the energy storage device 300. The energy storage device 300 inverts the output to provide a second AC power supply to other load branches. In the circuit breaker 100 provided in this application embodiment, the above process, due to the addition of the backup power supply 106, enables the circuit breaker 100 to achieve stable power failure detection of the first AC power supply 200, thereby accurately controlling the inverter output of the energy storage device 300, realizing seamless power supply switching between the mains power and the energy storage device 300, and increasing the safety and flexibility of the power supply system. The backup power supply provides power to the circuit breaker separately, reducing installation costs.

[0039] Please see Figure 2 and Figure 3 In some embodiments, the backup power supply 106 is connected between the first terminal G1 of the switch 101 and the power module 105; or the backup power supply 106 is connected to the power module 105.

[0040] Specifically, when the backup power supply 106 is connected between the first terminal G1 of the switch 101 and the power module 105, the first AC power supply 200 can supply power to the backup power supply 106. After storing a certain amount of electricity, the backup power supply 106 can also be directly connected to the power module 105. Furthermore, when the first AC power supply 200 is supplying power normally, the backup power supply 106 can be charged through the power module 105.

[0041] In some embodiments, the backup power supply 106 is connected to the power module 105, and the backup power supply 106 supplies power to the communication module 102, the detection module 103 and the control module 104 through the power module 105.

[0042] It is understandable that in the event of a power failure of the first AC power supply 200, the backup power supply 106 can replace the first current source to supply power to the communication module 102, the detection module 103 and the control module 104, so that the circuit breaker 100 can disconnect in time and communicate with the energy storage device 300.

[0043] Please see Figure 4In some embodiments, the backup power supply 106 is connected to the first terminal G1 and / or the second terminal G2 of the switch 101 to be charged by the first AC power supply 200 and / or the energy storage device 300.

[0044] Among them, the second terminal G2 of switch 101 is connected to the second AC power supply provided by energy storage device 300, and the second AC power supply can supply power to circuit breaker 100.

[0045] It is understandable that the backup power supply 106, as an independent power source within the circuit breaker 100, needs to be directly connected to the power module 105 to supply power to each module. The backup power supply 106 can be connected at one end to the first terminal G1 of the switch 101 and at the other end to the power module 105, or both ends can be directly connected to the two ends of the power module 105. Both modes allow the first AC power supply 200 to charge the backup power supply 106. When one end of the backup power supply 106 is connected to the first terminal G1 of the switch 101, the power module 105 can be connected to the second terminal G2 of the switch 101. Therefore, in this case, the second AC power supply provided by the energy storage device 300 at the load end can charge the backup power supply 106 of the circuit breaker 100.

[0046] Please see Figure 5 and Figure 6 In some embodiments, the backup power supply 106 includes an electrical connection port 107, through which the backup power supply 106 is connected to an external power supply 800 for charging.

[0047] The external power supply 800, as an independent charging component outside the circuit breaker 100, can provide appropriate voltage and current power to each module of the circuit breaker 100 to directly power each module of the circuit breaker 100; the external power supply 800 can also charge the backup power supply 106 through the electrical connection port 107 to ensure that the backup power supply 106 has enough power to support the basic operation of the circuit breaker 100 modules when the first AC power supply 200 fails.

[0048] In some embodiments, switch 101 is a normally open switch 101; or, control module 104 controls switch 101 to open when it determines that the first AC power supply 200 has lost power based on the first detection signal.

[0049] Among them, the normally open switch 101 achieves automatic control through the working principle of electromagnetic relay. When the electromagnet coil is not energized, the contacts remain open, and when energized, the contacts close to form a circuit.

[0050] Specifically, in the embodiments provided in this application, the circuit breaker 100 can be disconnected in two ways. First, when the switch 101 is a normally open switch 101, after the first AC power supply 200 is de-energized, the normally open switch 101 automatically disconnects due to the action of the relay, and the backup power supply module 106 replaces the first AC power supply 200 to supply power to each module of the circuit breaker 100. When the detection module 103 detects the first detection signal and confirms that the first AC power supply 200 has returned to normal, the controller 1041 of the control module 104 controls the motor 1042 to drive the switch 101 to close according to the first detection signal. Second, when the switch 101 is not a normally open switch 101, after the first AC power supply 200 is de-energized, the backup power supply 106 replaces the first AC power supply 200 to supply power to each module of the circuit breaker 100. When the detection module 103 detects the first detection signal and confirms that the first AC power supply 200 is de-energized, the controller 1041 of the control module 104 controls the motor 1042 to drive the switch 101 to open according to the first detection signal. When the first AC power supply 200 returns to normal, the detection module 103 detects the first detection signal and confirms that the first AC power supply 200 has returned to normal. The controller 1041 of the control module 104 controls the motor 1042 to drive the switch 101 to close according to the first detection signal.

[0051] In some embodiments, the control module 104 is further configured to send a first signal to the energy storage device 300 via the communication module 102 when the first AC power supply 200 fails and the power of the energy storage device 300 is greater than the preset backup power, so that the energy storage device 300 provides a second AC power supply to other load branches.

[0052] In some embodiments, the control module 104 is further configured to send a power supply stop signal to the energy storage device 300 via the communication module 102 when the power of the energy storage device 300 is less than or equal to a preset backup power, so that the energy storage device 300 stops providing the second AC power to other load branches and controls the switch 101 to close.

[0053] The preset reserve power refers to the minimum power threshold preset in the energy storage device 300, which can at least meet the basic power needs of key loads in the household power grid (such as lighting, refrigerators, medical equipment, etc.) for a certain period of time.

[0054] In some embodiments, the control module 104 is also configured to control the switch 101 to close when the energy storage device 300 is disconnected from power.

[0055] In some embodiments, the control module 104 is further configured to send a second signal to the energy storage device 300 via the communication module 102 when the first AC power supply 200 is determined to be powered on based on the first detection signal, so that the energy storage device 300 disconnects the power supply.

[0056] The second signal has two operating modes. The first mode refers to the signal sent by the control module 104 to the energy storage device 300 via the communication module 102 after the detection module 103 determines that the first AC power supply 200 has recovered. This second signal indicates that the first AC power supply 200 has returned to normal, and the energy storage device 300 determines that the first AC power supply 200 has been powered on and disconnects the power supply based on the second signal. The second mode is that the control module 104 directly sends a disconnection second signal to the energy storage device 300, and the energy storage device 300 directly disconnects.

[0057] Specifically, the communication module 102 obtains power information through continuous bidirectional data communication with the energy storage device 300 and sends it to the control module 104. The controller 1041 of the control module 104 controls the motor 1042 accordingly based on the power value Q of the energy storage device 300 and the preset backup power value Q0. In the event of a power failure of the first AC power supply 200: if Q is greater than Q0, it indicates that the energy storage device 300 has sufficient power to supply the load. The communication module 102 sends a first signal to the energy storage device 300 so that the energy storage device 300 provides a second AC power supply to other load branches via inverter output. If Q is less than or equal to Q0, it indicates that the energy storage device 300 does not have sufficient power to supply the load. The communication module 102 sends a stop power supply signal to the energy storage device 300 so that the energy storage device 300 stops inverter output and stops providing a second AC power supply to other load branches to avoid over-discharge. It also controls the switch 101 to close and waits for the first AC power supply 200 to be restored before continuing to use the first AC power supply 200 to supply power to the load.

[0058] In some embodiments, the energy storage device 300 replaces the first AC power supply 200 to supply power to the load. The energy storage device 300 can also be used for daily household electricity use, and can autonomously set the power consumption plan when the first AC power supply 200 is normal.

[0059] For example, in actual household electricity consumption, peak and off-peak electricity rates may be divided according to the grid load. Peak and off-peak electricity rates refer to dividing the electricity consumption time of the day into peak and off-peak periods, with different electricity prices for different time periods. Generally, electricity prices are higher during peak periods and lower during off-peak periods. The solution provided in this application embodiment can achieve the following: during peak electricity consumption periods, the control module 104 controls the circuit breaker 100 to open, thereby reducing or avoiding the use of high-priced electricity during peak periods, and instead using the relatively lower-priced energy storage device 300 to reduce electricity costs; while during off-peak electricity consumption periods, the circuit breaker 100 is controlled to close, so as to supply power and charge the energy storage device 300.

[0060] Please see Figure 7 In some embodiments, the detection module 103 is connected to the second terminal G2 of the switch 101. The detection module 103 is also used to detect whether the second terminal G2 of the switch 101 is de-energized and generate a second detection signal characterizing whether the energy storage device 300 is de-energized.

[0061] The second detection signal is a logic signal generated by the detection module 103 when it detects at the second terminal G2 of the switch 101, which can be recognized by the control module 104 and reflects the state of the second AC power supply (energized or de-energized).

[0062] Specifically, the detection module 103 continuously monitors the load terminal signal of the second terminal G2 of the switch 101. The load terminal signal includes original electrical parameters (such as voltage and waveform) representing the state of the second AC power supply. The input signal is sampled, processed, and compared with a preset normal operating threshold to generate a logic signal containing information about the state of the second AC power supply, namely the second detection signal.

[0063] In some embodiments, the control module 104 is further configured to control the switch 101 to close when it is determined, based on the first detection signal and the second detection signal, that the first AC power supply 200 is powered on and the energy storage device 300 is powered off.

[0064] Understandably, to ensure higher safety, the detection module 103 continuously monitors the signals at the first terminal G1 and the second terminal G2 of the switch 101: the first detection signal detected by the detection module 103 at the first terminal G1 of the switch 101 reflects the status of the first AC power supply 200 (mains power); the second detection signal detected by the detection module 103 at point G1 reflects the status of the second AC power supply (energy storage device 300). By establishing a detection and isolation mechanism for the power supply status on the load side, the status of the energy storage device 300 on the load side can be obtained in a timely manner, avoiding the grid connection problem between the mains power supply and the energy storage device 300 when the load branch is connected to the second AC power supply, which could lead to damage to the load. Since the phases of the AC power supply and the AC power supply of the energy storage device 300 may be inconsistent, grid connection could result in damage to the load.

[0065] Please see Figure 8 In some embodiments, the circuit breaker 100 and the energy storage device 300 are each communicatively connected to the same mobile terminal 900. The energy storage device 300 can establish a communication connection with the circuit breaker 100 through the mobile terminal 900. The circuit breaker 100 can be used to control the power supply status of the energy storage device 300 and the household load 400, and transmit the power supply status to the mobile terminal 900 via communication so that the mobile terminal 900 can display the power supply information.

[0066] For example, circuit breaker 100 can be linked to a home electricity application on mobile terminal 900 for communication. If energy storage device 300 supports wireless communication, it can also communicate with circuit breaker 100 via the home electricity application on mobile terminal 900. When the linked energy storage device 300 is powered on, it can communicate with circuit breaker 100 via wireless communication.

[0067] Specifically, after the circuit breaker 100, energy storage device 300, and mobile terminal 900 establish a communication relationship, the circuit breaker 100 can control the energy storage device 300 to activate its AC output function and output AC power when a mains power failure is detected. Furthermore, the circuit breaker 100 can also transmit the power supply status of the energy storage device 300 activating its AC output function to supply AC power to the household load 400 to the household electricity application on the mobile terminal 900, and can display the power supply status on the mobile terminal 900 application. This power supply status can include information such as the electrical connection between the energy storage device 300 and the household load 400, and the duration of power supply.

[0068] For example, the application of the mobile terminal 900 can display the electrical connection status between the energy storage device 300 and the household load 400. If the electrical connection between the energy storage device 300 and the household load 400 is normal, the energy storage device 300 can supply power to the household load 400 normally, and the application will display the status of normal connection between the two. If the electrical connection between the energy storage device 300 and the household load 400 is disconnected, the energy storage device 300 stops supplying power to the household load 400, and the application will display the status of disconnection between the two.

[0069] In this way, users can conveniently know the power supply status of the energy storage device 300 to the household load 400 in real time through the mobile terminal 900.

[0070] Please see Figure 8 In some embodiments, the communication module 102 of the circuit breaker 100 includes a first communication unit 1021. The energy storage device 300 includes a second communication unit 301, and the first communication unit 1021 and the second communication unit 301 are respectively communicatively connected to the mobile terminal 900. The second communication unit 301 can establish a communication connection with the first communication unit 1021 through the mobile terminal 900.

[0071] In other words, the circuit breaker 100 of this application can have wired or wireless communication functions, and is equipped with a first communication unit 1021, which may include an IoT card, etc. The connected energy storage device 300 can also have wired or wireless communication functions, and is equipped with a second communication unit 301, which may also include an IoT card, etc. The first communication unit 1021 and the second communication unit 301 can be mutually bound through a mobile terminal 900 to establish a wireless communication relationship, realizing remote intelligent control of the circuit breaker 100 on the connection and disconnection of the energy storage device 300 and the household load 400 through the mobile terminal 900, making it more intelligent.

[0072] Additionally, it is understandable that if the user selects an energy storage device 300 without wireless communication capabilities, the energy storage device 300 cannot be bound to the circuit breaker 100. In this case, the connection and disconnection of the energy storage device 300 can be manually operated by the user, so that the energy storage device 300 without wireless communication capabilities can also have the function of home emergency backup power.

[0073] In some implementations, the circuit breaker 100 is also used to receive user control commands from the mobile terminal 900 and control the connection between the energy storage device 300 and the household load 400 according to the user control commands.

[0074] Specifically, user control commands may include, for example, switching control commands for the energy storage device 300, control commands for adjusting the output power of the energy storage device 300, switching control commands for the circuit breaker 100, or other control commands, without limitation.

[0075] Understandably, since the circuit breaker 100, the energy storage device 300, and the mobile terminal 900 establish a communication relationship, not only can the circuit breaker 100 and the energy storage device 300 transmit information to the mobile terminal 900 and display it on the application of the mobile terminal 900, but similarly, users can also remotely control the energy storage device 300 and the circuit breaker 100 through the home electricity application of the mobile terminal 900, making it more convenient, faster, and more intelligent.

[0076] Thus, this application establishes a local area network by binding the energy storage device 300 with wireless communication function and the circuit breaker 100 through the same mobile terminal 900, enabling users to remotely control the operation of the energy storage device 300 and the circuit breaker 100 through the network on the mobile terminal 900, which is convenient for users to use and manage, and makes the control more intelligent.

[0077] In some implementations, when the energy storage device 300 is powered on, the circuit breaker 100 is used to read the energy storage information of the energy storage device 300 and display the energy storage information on the mobile terminal 900.

[0078] Specifically, the energy storage information includes the model of the energy storage device 300, its power supply capacity, and its remaining capacity.

[0079] Thus, this application establishes a local area network by binding the energy storage device 300 with wireless communication function and the circuit breaker 100 through the same mobile terminal 900. The circuit breaker 100 can automatically read the energy storage information of the energy storage device 300 and transmit the energy storage information to the mobile terminal 900 and display it on the mobile terminal 900, so that users can view the energy storage information of the energy storage device 300 in real time through the mobile terminal 900.

[0080] In some embodiments, the circuit breaker 100 is also used to issue a mains power supply alert when mains power is detected during the process of the energy storage device 300 supplying power to the household load 400.

[0081] Specifically, if mains power is restored during the process of energy storage device 300 supplying power to household load 400, circuit breaker 100 detects the restoration and can notify the user of the restoration via a pre-set notification method. For example, the user can be notified of the restoration via sound and light alerts, or via push notifications to a mobile terminal 900 that is wirelessly connected to circuit breaker 100 via an application.

[0082] When a user receives a notification from the circuit breaker 100 that the mains power has been restored, they can manually turn off the AC output function of the energy storage device 300 and then manually close the switch 101 to restore the mains power supply.

[0083] When the circuit breaker 100 and the energy storage device 300 are bound to the same mobile terminal 900 to establish a local area network, the user receives a notification of a mains power call. The user can also remotely turn off the AC output function of the energy storage device 300 through the application on the mobile terminal 900, and then restore the mains power supply by setting the circuit breaker 100 to close switch 101 or by manually closing switch 101 through the mobile terminal 900.

[0084] In one example, if the circuit breaker 100 issues a voice prompt, the voice prompt could be: "Main power has been restored. Please turn off the AC power output function of the energy storage device and then close the main circuit switch!"

[0085] Understandably, if the AC output function of the energy storage device 300 is not turned off first to disconnect the electrical connection between the energy storage device 300 and the household load 400, the closed switch 101 cannot be unlocked. Therefore, when the circuit breaker 100 of this application detects a mains power supply while the energy storage device 300 is supplying power to the household load 400, it issues a mains power supply reminder, which can remind the user to turn off the AC output function of the energy storage device 300 in time to unlock the closed switch 101 and ensure the normal operation of the circuit inside the household power distribution network 10.

[0086] Thus, this application can issue a mains power supply prompt when the mains power is detected during the process of the energy storage device 300 supplying power to the household load 400, so that the user can promptly shut down the AC output function of the energy storage device 300 and unlock the closed switch 101 to ensure the normal operation of the circuit inside the household power distribution network 10.

[0087] Please see Figure 9In some embodiments, the circuit breaker 100 also includes a motor 1042. The control module 104 is connected to the detection module 103 and the motor 1042 respectively. The motor 1042 is connected to the switch 101. The control module 104 is used to control the motor 1042 to disconnect the switch 101 and control the energy storage device 300 to supply power to the household load 400 when the detection module 103 detects that the first terminal G1 is de-energized and the household load 400 is connected to the energy storage device 300.

[0088] When the mains power fails, the detection module 103 can control the motor 1042 to drive the switch 101 to disconnect, thus disconnecting the household load 400 from the mains power and making the household load 400 an independent module. At this time, if the user has an energy storage device 300, they can connect the energy storage device 300 to the household load 400 and activate its AC output function. The energy storage device 300 can be connected to any wall socket 500 in the home. In other words, this application allows the AC power from the energy storage device 300 to be supplied to the household load 400 through a wall socket 500 in any room of the home, thereby providing AC power to the entire household.

[0089] For example, such as Figure 10 As shown, the energy storage device 300 can be connected to a wall socket 500 in the living room, or it can be connected to a wall socket 500 in another room. This application can determine the connection location of the energy storage device 300 based on the user's convenient access location, and can also determine the connection location of the energy storage device based on the maximum power of the energy storage device 300 used.

[0090] Thus, when the detection module 103 detects that the first terminal G1 is de-energized and the household load 400 is connected to the energy storage device 300, the present application can control the motor 1042 to work through the control module 104 to disconnect the switch 101 and control the energy storage device 300 to supply power to the household load 400. That is, the power supply source of the household load 400 can be switched through the circuit breaker 100 composed of the control module 104, the detection module 103 and the motor 1042.

[0091] Please see Figure 9In some embodiments, the motor 1042 includes a mechanical transmission unit 10421 and a mechanical locking unit 10422. The mechanical locking unit 10422 is connected to the mechanical transmission unit 10421, and both the mechanical transmission unit 10421 and the mechanical locking unit 10422 are connected to the control module 104. The control module 104 is also configured to control the mechanical transmission unit 10421 to move to disconnect the switch 101 when the first terminal G1 is de-energized, and to control the mechanical locking unit 10422 to lock the mechanical transmission unit 10421 to keep the switch 101 in the off state for a preset period of time after the energy storage device 300 begins to supply power to the household load 400.

[0092] Specifically, the mechanical transmission unit 10421 can be a drive shaft. Correspondingly, the circuit breaker 100 also includes a drive shaft control circuit connected to the control module 104. When the mains power fails, the detection module 103 can control the drive shaft to rotate through the drive shaft control circuit as long as it detects the mains power failure, thereby controlling the switch 101 to open, so that the household load 400 is disconnected from the mains power, making the household load 400 an independent module.

[0093] The preset time can be, for example, 0 seconds (s), 0.1s, 0.2s, 0.3s, 0.4s, 0.5s, 0.6s, 0.7s, 0.8s, or 1s, and is not limited here. When the preset time is 0s, the control module 104 can simultaneously control the mechanical locking unit 10422 to lock the mechanical transmission unit 10421 after the first terminal G1 loses power and the energy storage device 300 starts supplying power to the household load 400, so as to keep the switch 101 in the open state. When the preset time is 0.1s, the control module 104 can control the mechanical locking unit 10422 to lock the mechanical transmission unit 10421 within 0.1s after the mains power fails and the energy storage device 300 starts supplying power to the household load 400, so as to keep the switch 101 in the open state.

[0094] Understandably, when the mains power fails and the energy storage device 300 provides AC power to the household load 400, or within a preset time, the control module 104 controls the mechanical locking unit 10422 to lock the mechanical transmission unit 10421. This locks the mechanical transmission unit 10421 in a rotating state where the switch 101 is in the open state, preventing the user from accidentally touching the switch 101 while the energy storage device 300 is supplying power to the household load 400, thus preventing the household load 400 from connecting to the mains power and causing the energy storage device 300 to malfunction and pose an electrical hazard.

[0095] In detail, when switch 101 is turned off and energy storage device 300 supplies power to household load 400, detection module 103 can simultaneously collect the current values ​​of the first terminal G1 and the second terminal G2, and control module 104 determines whether there is electricity on both sides of the first terminal G1 and the second terminal G2 based on the current values.

[0096] If the detection module 103 samples a current value of 0 at the first terminal G1, and the detection module 103 samples a current value of not 0 or a large current value at the second terminal G2, then the control module 104 can determine that the first terminal G1 is not powered and the mains power is still in a power-off state, while the second terminal G2 is powered. Therefore, the control module 104 can control the mechanical locking unit 10422 to lock the mechanical transmission unit 10421 to keep the switch 101 in the open state, and record that the home power distribution network 10 is in the energy storage emergency backup power state at this time.

[0097] If the detection module 103 samples a current value that is not 0 or is a large current value at the first terminal G1, and the detection module 103 samples a current value that is not 0 or is a large current value at the second terminal G2, then the control module 104 can determine that the first terminal G1 is energized, the mains power is on, and the second terminal G2 is energized. Therefore, the control module 104 can control the mechanical locking unit 10422 to lock the mechanical transmission unit 10421 to keep the switch 101 in the off state and remind the user that the mains power is on, so that the user can turn off the AC power output function of the energy storage device 300 in time or disconnect the energy storage device 300 from the energy storage access terminal 30, and then turn off the switch 101 manually or through the application (APP) on the mobile terminal 900 to restore the mains power to supply power to the household load 400.

[0098] If the detection module 103 samples a non-zero or large current value at the first terminal G1, and the detection module 103 samples a zero current value at the second terminal G2, then the control module 104 can determine that the first terminal G1 is energized, the mains power is restored, and the second terminal G2 is de-energized. This indicates that the energy storage device 300 has either shut down its AC power output function or disconnected itself from the energy storage access terminal 30, and the energy storage device 300 has stopped supplying power to the household load 400. Therefore, the control module 104 can directly control the closing switch 101 to restore mains power to the household load 400.

[0099] like Figure 9 As shown, the control module 104 is electrically connected to the first end of the detection module 103, the second end of the detection module 103 is electrically connected to the second end G2, and the third end of the detection module 103 is electrically connected to the first end G1. The detection module 103 is used to collect electrical signals from the second end G2 and the first end G1. The control module 104 is used to determine whether the first end G1 is energized and whether the second end G2 is energized based on the electrical signals, and to control the mechanical locking unit 10422 to lock or unlock the mechanical transmission unit 10421, or to control the switch 101 to close or open.

[0100] Specifically, the detection module 103 can collect the electrical signals from the second terminal G2 and the first terminal G1, and then send the sampled electrical signals to the control module 104. This allows the control module 104 to determine whether there is power at the mains input terminal and whether there is power at the second terminal G2, and control the switch 101 to close or open accordingly. The electrical signals can be current signals or voltage signals, and there are no restrictions on their use.

[0101] In detail, when the detection module 103 samples a current value of the first terminal G1 that is not 0 or is a large current value, and the household load 400 is not connected to the energy storage device 300, the control module 104 can determine that the first terminal G1 is energized, that is, determine that the mains power is normal. At this time, the switch 101 can be controlled to close, so that the mains power supplies the household load 400.

[0102] When the detection module 103 samples a current value of 0 at the first terminal G1 and the household load 400 is connected to the energy storage device 300, the control module 104 can determine that the first terminal G1 is not connected to the mains power, that is, the mains power is off. At this time, the switch 101 can be controlled to open, so that the energy storage device 300 supplies power to the household load 400.

[0103] In other words, the circuit breaker 100 of this application can collect the electrical signals of the first terminal G1 and the second terminal G2 in real time by setting the detection module 103, so that the control module 104 can determine whether there is power on both sides of the mains power and the household load 400, and then make corresponding intelligent control to bring convenience to the user's life. At the same time, it can ensure the convenience and safety of the user in the process of using the energy storage device 300 for household emergency backup power, and can avoid the abnormal situation of short circuit between the energy storage device 300 and the mains power, thus ensuring the safety of the user in using the energy storage device 300 for emergency power supply.

[0104] Thus, the circuit breaker 100 of this application can lock the mechanical transmission unit 10421 by controlling the mechanical locking unit 10422 through the control module 104 at the moment of mains power failure and when the energy storage device 300 provides AC power to the household load 400, or within a preset time, thereby preventing circuit failure when the energy storage device 300 supplies power to the household load 400 and ensuring circuit safety when the energy storage device 300 supplies power.

[0105] In some embodiments, this application also provides a distribution box 700, including the circuit breaker 100 in the above embodiments.

[0106] The distribution box 700 is a metal or insulated plastic enclosure integrating various electrical components. The circuit breaker 100 is the core component of the distribution box 700, responsible for controlling the connection and disconnection of the primary AC source and load, protecting the circuit from overload and short circuit damage. In addition to the circuit breaker 100, the distribution box 700 also includes a wiring system connecting each load branch and a circuit breaker 600. The distribution box 700 makes it easier to connect and disconnect power to the entire household or a specific circuit. By scientifically and rationally distributing the single mains power supply to multiple independent circuits in different areas of the household through the distribution box 700, zoned and functional power supply can be achieved.

[0107] In some embodiments, this application also provides a home power distribution network 10, including a distribution box 700, an energy storage device 300, and multiple load branches.

[0108] like Figure 1 The household power distribution network 10 includes a first AC power source 200, a distribution box 700, and multiple load branches. The load branches include branches containing m household loads 400 that are only electrical devices, and branches containing n energy storage devices 300.

[0109] The energy storage device 300 is connected to the power supply branch via a power supply interface. The energy storage device 300 supplies power to multiple load branches via the power supply interface.

[0110] In some embodiments, the energy storage device 300 is connected to the load branch via a grid-connected / off-grid interface. The grid-connected / off-grid interface allows the energy storage device 300 to switch between grid-connected and off-grid modes. In grid-connected mode, the energy storage device 300 provides a connection to the public power grid, enabling charging or discharging operations and participation in grid demand response or ancillary services. In off-grid mode, the energy storage device 300 is disconnected from the public power grid, forming an independent microgrid to supply power to critical loads on other local load branches, ensuring the continuous operation of these critical loads.

[0111] Among them, the household load 400 includes air conditioners, refrigerators, washing machines, electric water heaters, televisions, lighting equipment, office equipment, and other appliances that only consume electricity.

[0112] Through the circuit breaker 100 provided in this embodiment, the home power distribution network 10 can automatically switch to power supply from the energy storage device 300 when the first AC power source 200 (such as mains power) fails; and automatically switch back to mains power supply when the mains power is restored. In addition, the home power distribution network 10 also controls the on / off switching of different loads through the distribution box 700 and wall sockets 500, realizing power supply management for various areas or devices in the home power distribution network 10. Through a communication interface, communication with the energy storage device 300 and other smart devices is achieved, supporting remote monitoring of the operating status of the home power distribution network 10 and remote control. The home power distribution network 10 can realize intelligent power management and load control, improving the flexibility and reliability of home electricity use.

[0113] Please see Figure 10 In some embodiments, the main output line L1 directly output from the distribution box 700 branches into multiple output branches L2. The main output line is electrically connected to the multiple output branches L2, and each output branch L2 includes a power input terminal G3, a household load connection terminal G4, and a circuit breaker 600. The power input terminal G3 is connected to the switch 101. The circuit breaker 600 is located between the power input terminal G3 and the household load connection terminal G4, and is used to control the connection / disconnection between the power input terminal G3 and the household load connection terminal G4. The circuit breaker 600 can be a circuit breaker.

[0114] Specifically, such as Figure 10 As shown, each of the bathroom, room 1, room 2, living room and kitchen in the user’s home is equipped with a corresponding output branch L2. That is, each household distribution box 700 is equipped with a household load access terminal G4 to be electrically connected to the household loads 400 of different household areas. The power consumption of the household loads 400 in each household area can be controlled by the closing and opening of the circuit breaker 600.

[0115] For example, when the circuit breaker 600 corresponding to the bathroom is closed, the power input terminal G3 of the bathroom and the household load connection terminal G4 are connected, allowing household loads 400 in the bathroom, such as lights and heaters, to connect to AC power and operate normally. When the circuit breaker 600 corresponding to the bathroom is open, the power input terminal G3 of the bathroom and the household load connection terminal G4 are disconnected, preventing household loads 400 in the bathroom, such as lights and heaters, from connecting to AC power and thus stopping operation.

[0116] For example, in the event of a mains power outage and the switch 101 being disconnected, if the energy storage device 300 is connected to the sixth wall socket 500 in the living room, its AC output function can be activated. Furthermore, through any wall socket 500 in any room of the household load 400, the connection location can be freely determined by the user or the power consumption, providing AC power to the entire household. The wall socket 500 can be a special wall socket 500 configured to provide power to the energy storage device 300.

[0117] Furthermore, when the energy storage device 300 supplies power to the household load 400 via the second terminal G2 connected to the wall socket 500 in the household area, the power supply of the energy storage device 300 is determined by the maximum power of the energy storage device 300 used and the overcurrent capability of the wall socket 500 and the circuit breaker 600 on the branch where the wall socket 500 is located.

[0118] Thus, the distribution box 700 of this application can achieve power control of loads in different household areas by setting multiple output branches L2.

[0119] In some embodiments, the circuit breaker 100 is also used to adjust the voltage range that the second terminal G2 can receive so that the output voltage of the energy storage device 300 matches the input voltage of the second terminal G2.

[0120] Understandably, since different countries have different requirements for household AC power, the output voltage of the energy storage device 300 will also differ when using it for emergency power supply. Therefore, the output voltage of the energy storage device 300 needs to be matched with the voltage used in the household in order for the energy storage device 300 to operate normally and supply power to the household load 400.

[0121] It is understood that in the specific implementation of this application, data related to user identity or characteristics is involved. When the above embodiments of this application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of related data must comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0122] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
