DETAILED DESCRIPTION

[0037] In order to make the purposes, technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application. Figs. 1 to 3 and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0038] The embodiments of the present application disclose a household light storage and charging integrated machine. Referring to Fig. 1 , the household light storage and charging integrated machine comprises a hybrid inverter 1, a photovoltaic module 2 and a battery system 3. The hybrid inverter 1 is electrically connected with the photovoltaic module 2, and the hybrid inverter 1 is electrically connected with the battery system 3. The hybrid inverter 1 comprises a grid-connected output interface 11, and the hybrid inverter 1 is electrically connected with a user load 5 and an external power grid 4 through the grid-connected output interface 11, wherein the user load 5 comprises a vehicle charging pile. A first AC circuit breaker 13 is arranged between the hybrid inverter 1 and the external power grid 4. The user load 5 is connected between the hybrid inverter 1 and the first AC circuit breaker 13 through a second AC circuit breaker 52. A charging pile control mainboard 51 is further arranged between the second AC circuit breaker 52 and the user load 5. The hybrid inverter 1 is used for adjusting a power supply device of the user load 5 according to a demand power of the user load 5.

[0039] Optionally, as shown in Fig. 2 , the grid-connected output interface 11 on the hybrid inverter 1 is a GRID port, which is a port used for connection with the external power grid 4. Further, a temporary load interface 12 is further arranged on the hybrid inverter 1, and the temporary load interface 12 is an EPS port.

[0040] Further, the grid-connected output interface 11 comprises a live wire input port, a zero wire input port and a protection wire input port. Please refer to Fig. 2 , in the present application, L refers to a live wire, N refers to a zero wire, and PE refers to a protection wire. Similarly, the temporary load interface 12 also comprises a live wire input port, a zero wire input port and a protection wire input port.

[0041] Optionally, the household light storage and charging integrated machine comprises a protection bus 6 (which can also be a ground bus), the protection bus 6 is used to ensure the safety of the household light storage and charging integrated machine. The protection bus 6 is electrically connected to the hybrid inverter 1, the charging pile control mainboard 51, the user load 5 and the external power grid 4.

[0042] Optionally, as shown in FIG. 5, the charging pile control mainboard 51 comprises an alternating current contactor 511 and a first current transformer 512. The alternating current contactor 511 is used to control the power-on or power-off of the user load 5. The first current transformer 512 is used to measure the current value passing through the charging pile control mainboard 51. Fig. 2

[0043] Illustratively, the charging pile control mainboard 51 can read the current value of the first current transformer 512 in real time. In the case that the aforementioned current value is greater than a preset current threshold, the charging pile control mainboard 51 can disconnect the alternating current contactor 511, thereby disconnecting the circuit in which the user load 5 is located, to ensure the safety of electricity use. In the case that the aforementioned current value is less than the preset current threshold, the alternating current contactor 511 is kept closed. By adopting the above technical solution, the charging pile control mainboard 51 can detect the current value through the alternating current contactor 511 and the first current transformer 512, and control the power-on or power-off of the user load 5.

[0044] Optionally, as shown in FIG. 5, the charging pile control mainboard 51 comprises an alternating current contactor 511 and a first current transformer 512. The alternating current contactor 511 is used to control the power-on or power-off of the user load 5. The first current transformer 512 is used to measure the current value passing through the charging pile control mainboard 51. Fig. 2

[0045] Optionally, as shown in FIG. 5, the charging pile control mainboard 51 comprises an alternating current contactor 511 and a first current transformer 512. The alternating current contactor 511 is used to control the power-on or power-off of the user load 5. The first current transformer 512 is used to measure the current value passing through the charging pile control mainboard 51. Fig. 2

[0046] ​​​Optionally, the hybrid inverter 1 can control the battery system 3 to charge or discharge. For example, when the battery system 3 discharges, the hybrid inverter 1 can convert the direct current output by the battery system 3 into alternating current and provide the alternating current to the user load 5. For example, when the battery system 3 charges, the hybrid inverter 1 can convert the alternating current provided by the external power grid 4 into direct current and use the direct current to charge the battery system 3.

[0047] Optionally, the hybrid inverter 1 also converts the direct current input by the photovoltaic module 2 into alternating current, which can be used by the battery system 3, the user load 5 or the external power grid 4.

[0048] Optionally, the hybrid inverter 1 can control the power supply system used by the user load 5. For example, the hybrid inverter 1 can provide the electrical energy generated by the photovoltaic module 2 to the user load 5, or the hybrid inverter 1 can provide the electrical energy stored in the battery system 3 to the user load 5.

[0049] Optionally, the input port of the external power grid 4 is provided with a quick plug-in AC connector 41, a second current transformer 42 is arranged between the first AC circuit breaker 13 and the quick plug-in AC connector 41, and the second current transformer 42 is also connected to the hybrid inverter 1; the second current transformer 42 provides first current data to the hybrid inverter 1; the hybrid inverter 1 is also used to adjust the output power when it is detected that the first current data indicates that the current flows to the external power grid 4, so as to achieve power balance. The quick plug-in AC connector 41 is used to control the on-off of the external power grid 4 and the user load 5. In some actual scenarios, when the amount of electricity generated by the photovoltaic module 2 exceeds the local load demand, there will be excess electricity flowing back into the external power grid 4, which will cause power quality problems of the power grid, affect the stability of the power grid, and cause safety accidents. When the second current transformer 42 detects that the current flows to the external power grid 4, the hybrid inverter 1 quickly adjusts its own output power to maintain power balance, thereby achieving zero power on the grid and preventing reverse flow.

[0050] Further, a second current transformer 42 is arranged between the quick plug-in AC connector 41 and the first AC circuit breaker 13. When the reading of the second current transformer 42 is greater than a preset reading threshold, the quick plug-in AC connector 41 is automatically disconnected, thereby cutting off the alternating current input of the external power grid 4 and ensuring the safety of the user's electricity consumption.

[0051] Optionally, please refer to Fig. 3 Fig. 3The charging pile control mainboard 51 comprises an emergency stop control circuit. The emergency stop control circuit comprises a relay 513, a relay switch 514 and a contact switch 515 controlled by the relay 513. The contact switch 515 is used to control the power supply or cut-off of the live wire at one end of the second AC circuit breaker 52. The relay switch 514 is used to control the on-off of the relay 513. When the relay 513 is in the power-on state, the relay 513 controls the contact switch 515 to be open. When the relay 513 is in the power-off state, the relay 513 controls the contact switch 515 to be closed. Therefore, the emergency stop control circuit is arranged to ensure that the charging pile control mainboard 51 can cut off the power supply of the user load in an emergency situation, thereby ensuring the safety of the user's power supply.

[0052] For example, the relay switch 514 is a temperature control switch. When it is detected that the external temperature is greater than a preset temperature, the relay switch 514 is closed, so that the relay 513 is in the power-on state, thereby cutting off the power supply of the user load 5, preventing the charging pile control mainboard 51 or the charging pile from being damaged due to the excessively high temperature, and further reducing the probability of fire.

[0053] For example, the relay switch 514 is electrically connected with the first current transformer 512. The relay switch 514 can read the current value of the first current transformer 512 in real time. When the aforementioned current value is greater than a preset current threshold value, the relay switch 514 can be closed, so that the relay 513 is in the power-on state, thereby cutting off the circuit in which the user load 5 is located, and ensuring the safety of the power supply.

[0054] Optionally, the third current transformer 43 is arranged between the first AC circuit breaker 13 and the quick plug-in AC connector 41. The third current transformer 43 is also connected to a DLB (Dynamic Load Balancing) interface 516 of the charging pile control mainboard 51. The third current transformer 43 is used to provide second current data to the charging pile control mainboard 51. The charging pile control mainboard 51 is also used to adjust the output power of the vehicle charging pile when it is detected that the second current data includes an amount of current other than that of the vehicle charging pile.

[0055] The household light storage and charging all-in-one machine provided by the embodiment of the application has the following implementation principles:

[0056] In an implementation scenario, when the photovoltaic assembly 2 generates electricity and the external power grid 4 supplies electricity, if the electricity generated by the photovoltaic assembly 2 is greater than the electricity required by the user load 5, the photovoltaic assembly 2 supplies electricity to the user load 5 and the battery system 3. If the electricity generated by the photovoltaic assembly 2 is less than the electricity required by the user load 5, the photovoltaic assembly 2 and the external power grid 4 supply electricity to the user load 5 and the battery system 3. By adopting the technical solution described above, in the case that the photovoltaic assembly generates electricity and the external power grid supplies electricity, the supply mode of the photovoltaic assembly and the external power grid is determined according to the electricity required by the user load, so as to ensure that the user load can be supplied with sufficient electricity.

[0057] In the present application, the electricity required by the user load 5 includes the total electricity of the vehicle charging pile and the household load, unless otherwise specified.

[0058] For example, when the photovoltaic assembly 2 generates electricity, the electricity required by the user load 5 is monitored in real time. The electricity generated by the photovoltaic assembly 2 is compared with the electricity required by the user load 5. If the electricity generated by the photovoltaic assembly 2 is less than the electricity required by the user load 5, the external power grid 4 is also used to supply electricity to the user load 5 on the basis of the photovoltaic assembly 2 supplying electricity to the user load 5, so as to ensure that the user load 5 can be supplied with sufficient electricity. If the electricity generated by the photovoltaic assembly 2 is greater than the electricity required by the user load 5, only the photovoltaic assembly 2 is used to supply electricity to the user load.

[0059] Further, if the electricity generated by the photovoltaic assembly 2 is greater than the electricity required by the user load 5, the battery system 3 is supplied with electricity by the photovoltaic assembly 2, so that the battery system 3 is in a charging state. In some other implementation modes, if the difference between the electricity generated by the photovoltaic assembly 2 and the electricity required by the user load 5 is less than the minimum charging electricity, the minimum charging electricity refers to the minimum electricity required for the battery system 3 to enter the charging state, the battery system 3 is charged by the external power grid 4 and the photovoltaic assembly 2 together. If the difference between the electricity generated by the photovoltaic assembly 2 and the electricity required by the user load 5 is greater than the minimum charging electricity, the battery system 3 is charged by the photovoltaic assembly 2.

[0060] In an implementation scenario, when the photovoltaic assembly 2 does not generate electricity and the external power grid 4 supplies electricity, if the remaining electricity of the battery system 3 is greater than the electricity required by the user load 5, the battery system 3 supplies electricity to the user load 5. If the remaining electricity of the battery system 3 is less than the electricity required by the user load 5, the battery system 3 and the external power grid 4 supply electricity to the user load 5. By adopting the technical solution described above, in the case that the photovoltaic assembly does not generate electricity and the external power grid supplies electricity, the supply mode of the battery system and the external power grid is determined according to the electricity required by the user load, so as to ensure that the user load can be supplied with sufficient electricity.

[0061] For example, the demand power of the user load 5 is monitored in real time when the photovoltaic assembly 2 does not generate electricity. The residual power of the battery system 3 is compared with the demand power. If the residual power of the battery system 3 is less than the demand power, the external power grid 4 is used to supply power to the user load 5 on the basis of that the battery system 3 supplies power to the user load 5, so that the user load 5 can be ensured to be supplied with sufficient power. If the residual power of the battery system 3 is greater than the demand power, only the battery system 3 is used to supply power to the user load.

[0062] Further, the external power grid 4 charges the battery system 3 when the residual power of the battery system 3 is less than the preset power. By using the above technical solution, when the residual power of the battery system is insufficient, the external power grid is used to charge the battery system, so that the residual power of the battery system is maintained above a certain level, which is beneficial to cope with various emergencies. The preset power is a preset empirical value, for example, the preset power is 10% of the battery system 3. When the external power grid 4 supplies power to the battery system 3, the battery system 3 stops supplying power to the user load 5.

[0063] In an implementation scenario, the hybrid inverter 1 further includes a temporary load interface 12. When the external power grid 4 does not supply power, the photovoltaic assembly 2 and the battery system 3 supply power to the user load 5, and the temporary load interface 12 outputs voltage. By using the above technical solution, when the external power grid does not supply power, the temporary load interface 12 on the hybrid inverter is used to output voltage, so that the user can use the temporary load interface 12 to supply power to important electrical appliances.

[0064] For example, when the external power grid 4 does not supply power, if the photovoltaic assembly 2 does not generate electricity, the battery system 3 alone supplies power to the user load 5. If the photovoltaic assembly 2 generates electricity, the photovoltaic assembly 2 and the battery system 3 jointly supply power to the user load 5.

[0065] For example, when the external power grid 4 does not supply power, the maximum output power of the hybrid inverter 1 is 6000W, and the load power of the temporary load interface 12 does not exceed 6000W.

[0066] Optionally, a power limiter is further arranged at the temporary load interface 12. When the load power of the temporary load interface 12 is greater than the maximum output power of the hybrid inverter 1, the power limiter closes the output voltage of the temporary load interface 12 and generates an alarm information, the alarm information including at least one of voice alarm, light alarm and text alarm. After a preset time period, the power limiter controls the temporary load interface to continue to output voltage.

[0067] Further, if the number of times that the power limiter closes the output voltage of the temporary load interface 12 reaches a preset number of times, the power limiter sends a maximum power adjustment request to the hybrid inverter, the maximum power adjustment request is used to increase the maximum output power of the hybrid inverter 1, and a prompt information is generated.

[0068] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any feature disclosed in the specification (including the abstract and drawings) can be replaced by other equivalent or similar features unless specifically stated otherwise. That is, each feature is only an example of a series of equivalent or similar features unless specifically stated otherwise.
