[0068] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0069] It should be understood that although the terms first, second, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first parameter may also be referred to as the second parameter, and similarly, the second parameter may also be referred to as the first parameter. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0070] With the development of technology, portable power supplies, as a kind of energy storage device, can provide power to various devices without an external power supply. They usually have multiple output interfaces and support powering multiple devices at the same time. In related technologies, portable power supplies usually have multiple power supply interfaces, which can support powering multiple loads at the same time, such as charging mobile phones through USB interfaces and providing power for laptops, lighting fixtures, small household appliances, etc. through AC interfaces. However, the use of multiple loads at the same time may cause the power supply voltage of the whole machine to decrease, affecting the normal operation of the loads and resulting in low power supply efficiency.

[0071] The control method of the energy storage power supply device provided in the embodiment of the present application dynamically controls the number of power supply ports in an effective state according to the remaining power of the energy storage power supply device, and gradually reduces the number of power supply ports in an effective state as the remaining power of the energy storage power supply device decreases, thereby avoiding the situation where the remaining power supply capacity of the energy storage power supply device cannot cover the power required to be output by multiple power supply ports due to powering too many loads at the same time. It can ensure that the energy storage power supply device uses the power supply ports in an effective state according to the remaining power to provide sufficient power to the power-consuming devices, so that the power-consuming devices connected to the effective power supply ports can operate normally, thereby ensuring the power supply performance and improving the power supply efficiency.

[0072] First, let's introduce the implementation environment of this application. Figure 1 , which shows a schematic diagram of a power supply system provided by an exemplary embodiment of the present application, and the power supply system includes: a device 110.

[0073] Device 110 is a terminal device for controlling an energy storage power supply device.

[0074] Optionally, the device 110 may be an energy storage and power supply device, or may be a control device independent of the energy storage and power supply device, which is not limited in the embodiments of the present application.

[0075] Energy storage power supply equipment is a device that provides electrical energy to electrical equipment based on its own stored energy.

[0076] The energy storage power supply device includes a plurality of power supply ports, which are used to output electric energy to the power-consuming equipment.

[0077] The device 110 may control the power supply state of the power supply port, where the power supply state is used to indicate the capability of the power supply port to output electrical energy.

[0078] The power supply status of the power supply port includes a valid state and an invalid state. The valid state is used to indicate that the power supply port has the ability to output power, and the invalid state is used to indicate that the power supply port does not have the ability to output power.

[0079] The power-consuming equipment obtains the electric energy provided by the energy storage power supply equipment by connecting to the power supply port in an effective state.

[0080] In some embodiments, the device 110 may dynamically control the power supply status of the power supply port according to the remaining power of the energy storage power supply device.

[0081] Illustratively, device 110 obtains a power parameter of an energy storage power supply device, where the power parameter is used to characterize the remaining power supply capacity of the energy storage power supply device, where the energy storage power supply device includes multiple power supply ports, which are used to output power to power-consuming devices; when the power parameter is in a first parameter range, n of the multiple power supply ports are controlled to be in a valid state, where the valid state is used to indicate that the power port has the ability to output power, and n is a positive integer; when the power parameter is in a second parameter range, m of the multiple power supply ports are controlled to be in a valid state, and m is a positive integer; wherein the remaining power supply capacity corresponding to the first parameter range is greater than the remaining power supply capacity corresponding to the second parameter range, and n is greater than m.

[0082] The above-mentioned terminal is optional. The terminal can be a portable power supply, a desktop computer, a laptop computer, a mobile phone, a tablet computer, an e-book reader, a Moving Picture Experts Group Audio Layer III (MP3) player, a Moving Picture Experts Group Audio Layer IV (MP4) player, a smart TV, a smart car, and other forms of terminal devices, which are not limited to the embodiments of the present application.

[0083] In some embodiments, the above-mentioned terminal may also be implemented as a server for controlling energy storage power supply equipment, which is not limited in the embodiments of the present application.

[0084] It is worth noting that the above-mentioned servers can be independent physical servers, or they can be server clusters or distributed systems composed of multiple physical servers. They can also be cloud servers that provide basic cloud computing services such as cloud services, cloud security, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDN), as well as big data and artificial intelligence platforms.

[0085] In some embodiments, the above server can also be implemented as a node in a blockchain system.

[0086] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards in the relevant regions. For example, the operating data and power parameters involved in this application are all obtained with full authorization.

[0087] To further explain, before collecting relevant user data (for example, historical operation data and power parameters involved in this application, etc.) and during the process of collecting relevant user data, this application can display a prompt interface, pop-up window or output voice prompt information. The prompt interface, pop-up window or voice prompt information is used to prompt the user that its relevant data is currently being collected, so that this application only starts to execute the relevant steps of obtaining user-related data after obtaining the user's confirmation operation on the prompt interface or pop-up window, otherwise (that is, when the user's confirmation operation on the prompt interface or pop-up window is not obtained), the relevant steps of obtaining user-related data are terminated, that is, the user's relevant data is not obtained. In other words, all user data collected by this application are collected with the user's consent and authorization, and the collection, use and processing of relevant user data need to comply with relevant laws, regulations and standards in the relevant regions.

[0088] For illustration, please refer to Figure 2 , which shows a flow chart of a control method for an energy storage power supply device provided by an exemplary embodiment of the present application. The method can be executed by a terminal, or by a server, or by both a terminal and a server. The present application embodiment takes the method executed by a terminal as an example for explanation. Figure 2 As shown, the method comprises the following steps:

[0089] Step 210: Acquire power parameters of the energy storage power supply device.

[0090] The power parameter is used to characterize the remaining power supply capacity of the energy storage power supply device. The energy storage power supply device includes multiple power supply ports, which are used to output power to power-consuming devices.

[0091] Energy storage power supply equipment is a device that converts its own stored energy into electrical energy to provide electrical energy to electrical equipment.

[0092] Optionally, the energy storage power supply equipment includes but is not limited to mechanical energy storage, electrochemical energy storage, electromagnetic energy storage, chemical energy storage, thermal energy storage, gravity energy storage and other energy storage types of power supply equipment, which is not limited in the embodiments of the present application.

[0093] Electrical devices include but are not limited to mobile phones, tablets, camping lights, car refrigerators, air conditioners, microwave ovens, ventilators, fans, and any other devices that can receive electrical energy through the power supply port.

[0094] Multiple power supply ports can output power to different types of electrical devices.

[0095] For different power output types, the multiple power supply ports include but are not limited to AC output ports, direct current (DC) output ports, USB output ports and other power supply ports of any output type.

[0096] For different types of power supply methods, multiple power supply ports include but are not limited to plug-in power supply ports, charging power supply ports, etc.

[0097] Among them, the plug-in power supply port uses a plug-in power supply method to output electric energy to the power-consuming equipment, and the charging power supply port uses a charging power supply method to output electric energy to the power-consuming equipment. The plug-in power supply method refers to a power supply method in which the electric energy output by the power supply port is immediately used to maintain the operation of the power-consuming equipment, and the charging power supply method refers to a power supply method in which the electric energy output by the power supply port is stored in the power-consuming equipment.

[0098] In response to different power requirements, the multiple power supply ports may further include power supply ports corresponding to different output powers, for example, power supply ports with rated output powers of 5 watts (W), 10 W, 220 W, and the like.

[0099] It is worth noting that the types of the above-mentioned power supply ports are only illustrative examples and are not limited to the embodiments of the present application.

[0100] The power parameters include, but are not limited to, the remaining power of the energy storage power supply device, the used power, the remaining continuous power supply time, and any other parameters that can be used to characterize the remaining power supply capacity of the device, and the embodiments of the present application are not limited to this.

[0101] Step 220: When the power parameter is within the first parameter range, control n power supply ports among the plurality of power supply ports to be in a valid state.

[0102] The valid state is used to indicate that the power supply port has the ability to output power, and n is a positive integer.

[0103] The number of power supply ports in a valid state among the multiple power supply ports is related to the parameter range in which the power parameter is located, that is, the number of power supply ports in a valid state is related to the remaining power supply capacity of the energy storage power supply device.

[0104] Indicatively, the number of power supply ports in a valid state is positively correlated with the remaining power supply capacity of the energy storage power supply device. The greater the remaining power supply capacity of the energy storage power supply device, the greater the number of power supply ports in a valid state.

[0105] In some embodiments, the plurality of power supply ports correspond to power supply switches respectively, and the power supply switches are used to control the power supply status of the power supply ports.

[0106] Illustratively, the switch state of the power switch includes a connected state and a disconnected state, wherein when the power switch is in the connected state, the power port is in a valid state; when the power switch is in the disconnected state, the power port is in an invalid state.

[0107] For example, when the power parameter is in the first parameter range, power switches corresponding to n power ports among the multiple power ports are controlled to be in a connected state, so that the n power ports are in a valid state.

[0108] In some embodiments, a plurality of power supply ports respectively correspond to priority parameters, and the priority parameters are used to indicate the power output priority corresponding to the power supply port.

[0109] Optionally, when the power parameter is in the first parameter range, n power supply ports among the multiple power supply ports are controlled to be in a valid state according to the priority parameter, wherein the power output priority corresponding to the n power supply ports in the valid state is higher than that of other power supply ports (i.e., power supply ports in an invalid state).

[0110] The above priority parameters may be preset for multiple power supply ports in the energy storage power supply device, or may be configured according to a priority configuration operation, or may be dynamically determined according to the real-time power supply conditions of multiple power supply ports, which is not limited in the embodiments of the present application.

[0111] Illustratively, when the power parameter is in the first parameter range, power switches corresponding to n power ports among the multiple power ports are controlled to be in a connected state according to the priority parameter, so that the n power ports are in a valid state.

[0112] Step 230: When the power parameter is within the second parameter range, control m power supply ports among the multiple power supply ports to be in a valid state, where m is a positive integer.

[0113] The remaining power supply capacity corresponding to the first parameter interval is greater than the remaining power supply capacity corresponding to the second parameter interval, and n is greater than m.

[0114] The number of power supply ports in an effective state is positively correlated with the remaining power supply capacity of the energy storage power supply device. Taking the power parameter including the remaining power of the energy storage power supply device as an example, as the remaining power of the energy storage power supply device decreases, the number of power supply ports in an effective state is reduced.

[0115] Illustratively, when the power parameter is in a first parameter range, n power supply ports among the multiple power supply ports are controlled to be in a valid state, and when the power parameter is in a second parameter range, the number of power supply ports in a valid state is controlled to decrease from n to m.

[0116] Among them, the m power supply ports in a valid state may include some of the n power supply ports mentioned above, and may also include other power supply ports different from the n power supply ports, which is not limited in the embodiment of the present application.

[0117] In some embodiments, in order to improve power supply efficiency while reducing the number of power supply ports in an effective state, different power supply ports may be cyclically controlled to be in an effective state.

[0118] Illustratively, when the power parameter is in the second parameter range, m first power ports and m second power ports among the multiple power ports are controlled to be in the effective state in turn.

[0119] Among them, at least one power supply port among the m first power supply ports is different from the m second power supply ports.

[0120] Optionally, m first power supply ports or m second power supply ports can be controlled to be in an effective state in turn at preset time intervals, or the length of time that the power supply port is in a continuous effective state can be determined based on the priority parameters corresponding to the power supply port, or the length of time that the power supply port is in a valid state can be dynamically determined based on the real-time power supply situation of the power supply port, etc. The embodiments of the present application are not limited to this.

[0121] Taking determining the duration of a power supply port being in a continuous valid state according to a priority parameter corresponding to the power supply port as an example, the power output priority indicated by the priority parameter corresponding to the power supply port is positively correlated with the duration of the power supply port being in a continuous valid state. For example, the m first power supply ports are different from the m second power supply ports. When the power parameter is in the second parameter interval, after controlling the m first power supply ports to be in a valid state according to the first continuous time, the m second power supply ports are controlled to be in a valid state according to the second continuous time and the cycle is repeated, wherein the power output priority corresponding to the m first power supply ports is higher than that of the m second power supply ports, and the first continuous time is greater than the second continuous time; the m first power supply ports include k third power supply ports and mk first power supply ports, and the m second power supply ports include k third power supply ports and mk second power supply ports, k is a positive integer and k<m, the k third power supply ports are the same power supply ports among the m first power supply ports and the m second power supply ports, and the power output priority corresponding to the k third power supply ports is higher than that of the mk first power supply ports and the mk second power supply ports.

[0122] Taking the example of dynamically determining the duration that the power supply port remains in an effective state based on the real-time power supply status of the power supply port, the real-time power supply status includes but is not limited to at least one of the power supply mode currently used by the power supply port, the power supply duration, and the power output power.

[0123] The duration that the m power supply ports are in an effective state in turn is related to the electric energy output by the power supply ports to the power-consuming equipment. When the electric energy continuously output by the m first power supply ports to the power-consuming equipment meets the first power supply requirement, the m second power supply ports are switched to an effective state.

[0124] In a schematic diagram, when the power parameter is in the second parameter interval, after controlling the m first power supply ports to be in an effective state for a first duration, the m second power supply ports are controlled to be in an effective state according to the second duration, and the process is repeated alternately. When the m first power supply ports are controlled to be in an effective state for a first duration, the electric energy continuously output by the m first power supply ports to the electric device meets the first power supply requirement. The first power supply requirement includes that the electric energy continuously output by the m first power supply ports to the electric device within the first duration can sustainably work for a second duration in a power-off state.

[0125] It is worth noting that the above-mentioned rotation control method is only an illustrative example and is not limited to this in the embodiments of the present application.

[0126] The method provided in the embodiment of the present application reduces the number of power supply ports in the effective state by shutting down the power supply ports in turn, while ensuring the normal operation of the power-consuming devices as much as possible, thereby improving the power supply efficiency.

[0127] Taking keeping m of n power ports in a valid state as an example, step 230 includes, when the power parameter is in the second parameter range, controlling nm of the n power ports to be in an invalid state, where the invalid state is used to indicate that the power port does not have the ability to output electrical energy.

[0128] Among them, controlling nm power supply ports among n power supply ports to be in an invalid state means switching nm power supply ports among n power supply ports from a valid state to an invalid state, and the states of other power supply ports (including the above-mentioned m power supply ports, and power supply ports among multiple power supply ports except the above-mentioned n power supply ports) remain unchanged.

[0129] Optionally, the nm power supply ports are controlled to be in an invalid state through a power supply switch.

[0130] Illustratively, when the power parameter is within the second parameter range, the power switches corresponding to the nm power supply ports are controlled to be in an off state.

[0131] Optionally, the nm power supply ports may be determined randomly, or may be selected based on a selection operation, or may be determined according to priority parameters corresponding to the power supply ports.

[0132] Illustratively, nm power supply ports are determined from n power supply ports according to the priority parameter, and the nm power supply ports are controlled to be in an invalid state, wherein the power output priority corresponding to the nm power supply ports is lower than that of the m power supply ports.

[0133] The control order of the power supply port based on the power quantity parameter being in an invalid state and the duration of the power supply port being in a valid state based on the power quantity parameter are related to the power output priority corresponding to the power supply port.

[0134] Indicatively, as the remaining power supply capacity indicated by the power parameter decreases, the power supply ports with higher power output priorities are preferentially kept in a valid state, that is, the power supply ports with lower power output priorities are preferentially controlled to be in an invalid state.

[0135] For illustration, please refer to Figure 3 , Figure 3 FIG. 1 is a schematic diagram of an intelligent control process based on device power provided by an exemplary embodiment of the present application. Figure 3 As shown, in order to gradually reduce the number of power supply ports in the effective state according to the reduction of the remaining power of the energy storage power supply device, step 310 is executed in sequence, and the user configures the power priority parameters or the factory default parameters; step 320, the user starts to use electricity and monitors the power; step 330, determines whether the power is between 50% and 100%, if not, executes step 340 to close the power supply port with the lowest priority; in the case where the power supply port with the lowest priority has been closed, step 350 is executed to determine whether the power is between 40% and 50%, if so, executes step 360 to close the power supply port with the second lowest priority; in the case where the power supply port with the second lowest priority has been closed, step 370 is executed to determine whether the power is between 10% and 20%, if so, executes step 380 to close the power supply port with a lower priority; in the case where the power supply port with a lower priority has been closed, step 390 is executed to determine whether the power has reached the minimum power, if so, execute step 301 to shut down.

[0136] To summarize, the method provided in the embodiment of the present application dynamically controls the number of power supply ports in an effective state according to the remaining power of the energy storage power supply device, and gradually reduces the number of power supply ports in an effective state as the remaining power of the energy storage power supply device decreases, thereby avoiding the situation where the remaining power supply capacity of the energy storage power supply device cannot cover the power required to be output by multiple power supply ports due to powering too many loads at the same time. It can ensure that the energy storage power supply device uses the power supply ports in an effective state according to the remaining power to provide sufficient power to the power-consuming devices, so that the power-consuming devices connected to the effective power supply ports can operate normally, thereby ensuring the power supply performance and improving the power supply efficiency.

[0137] In some embodiments, by controlling the power supply port to be in an effective state, the power supply port has the ability to output electric energy to the power-consuming device. When the energy storage power supply device outputs electric energy to multiple power-consuming devices based on multiple power supply ports, the power supply capacity of the energy storage power supply device will be weakened as the output electric energy is limited by the energy storage. When the remaining power supply capacity of the energy storage power supply device drops to a certain level, the energy storage power supply device will not be able to maintain the output of electric energy to multiple power supply devices at the same time. Therefore, the number of power supply ports in an effective state is reduced, and the load of the energy storage power supply device is reduced to ensure that normal power supply can continue to be provided to some power-consuming devices. Specifically, the number of power supply ports in an effective state can be reduced by switching some power supply ports to an invalid state.

[0138] For illustration, please refer to Figure 4 , which shows a flow chart of a control method for an energy storage power supply device provided by an exemplary embodiment of the present application. The method can be executed by a terminal, or by a server, or by both a terminal and a server. The present application embodiment takes the method executed by a terminal as an example for explanation. Figure 4 As shown, the above step 230 includes the following steps:

[0139] Step 231 : when the power parameter is within the second parameter range, control nm power supply ports among the n power supply ports to be in an invalid state.

[0140] The invalid state is used to indicate that the power supply port is not capable of outputting power.

[0141] Optionally, the nm power supply ports may be determined randomly, or may be selected based on a selection operation, or may be determined according to priority parameters corresponding to the power supply ports.

[0142] Illustratively, taking the selection of nm power ports from n power ports based on a selection operation as an example, multiple power ports may respectively correspond to physical buttons, which are used to select the power ports that need to be switched to an invalid state; or, a control program of an energy storage power supply device is installed in the terminal, and the power port that needs to be switched to an invalid state is selected by triggering a port control provided in the control program; or, multiple power ports correspond to different port names, and the energy storage power supply device corresponds to a voice acquisition device, which receives voice control content, identifies the port name, and switches the designated power port to an invalid state.

[0143] It is worth noting that the above selection method is only an illustrative example and is not limited to this in the embodiments of the present application.

[0144] Taking controlling the power supply port according to the priority parameter as an example, the above step 231 may include the following steps:

[0145] In the first step, nm power supply ports are determined from n power supply ports according to priority parameters.

[0146] The priority parameter is used to indicate the power output priority corresponding to the power supply port.

[0147] The power output priorities corresponding to the nm power supply ports are lower than those of the m power supply ports.

[0148] The control order of the power supply port based on the power quantity parameter being in an invalid state and the duration of the power supply port being in a valid state based on the power quantity parameter are related to the power output priority corresponding to the power supply port.

[0149] Indicatively, as the remaining power supply capacity indicated by the power parameter decreases, the power supply ports with higher power output priorities are preferentially kept in a valid state, that is, the power supply ports with lower power output priorities are preferentially controlled to be in an invalid state.

[0150] Schematically, the correspondence between the priority parameter and the power parameter range is as follows:

[0151] The priority parameter of power supply port 1 is 1, and the device power parameter range is 10%-100% available;

[0152] The priority parameter of power supply port 2 is 2, and the device power parameter range is 20%-100% available;

[0153] The priority parameter of power supply port 3 is 2, and the device power parameter range is 20%-100% available;

[0154] The priority parameter of power supply port 4 is 3, and the device power parameter range is 30%-100% available;

[0155] …

[0156] The priority parameter of power supply port n is x, and the device power range is y%-100% available.

[0157] Among them, the smaller the value of the priority parameter is, the higher the priority of the electric energy output is, x is the priority parameter with the smallest value, and the interval length of y%-100% is the smallest.

[0158] It is worth noting that the correspondence between the above priority parameters and the power parameter ranges is only an illustrative example and is not limited to this in the embodiments of the present application.

[0159] In some embodiments, it is necessary to obtain priority parameters corresponding to a plurality of power supply ports respectively. Optionally, the priority parameter is obtained in at least one of the following ways:

[0160] The first method is to read the priority parameters preset for multiple power supply ports in the energy storage power supply device.

[0161] Illustratively, priority parameters may be preset according to the type of electrical equipment corresponding to the power supply port. For example, priority parameters may be assigned in descending order according to the rated power of the electrical equipment. The higher the rated power, the higher the power output priority of the power supply port.

[0162] In some embodiments, multiple sets of priority parameters can also be preset according to different power supply scenarios. For example, for camping scenarios, a higher power output priority is preset for the power supply ports corresponding to camping equipment such as camping lights, ovens, fans, and speakers; for temporary office scenarios, a higher power output priority is preset for the power supply ports corresponding to office equipment such as computers, notebooks, and mobile phones.

[0163] By identifying the power supply scenario in which the energy storage power supply device is located, the priority parameters preset for the corresponding scenario are read.

[0164] Optionally, the power supply scenario may be determined by receiving a scenario configuration operation, or by automatically identifying the power supply scenario.

[0165] Illustratively, through the positioning function, the location information of the energy storage power supply equipment is obtained, and the environmental image within the preset range of the energy storage power supply equipment is collected, and the power supply scene is determined based on the location information and the environmental image. For example, when the location information indicates that the energy storage power supply equipment is in a park area and the environmental image includes camping equipment, the camping scene is automatically identified and the priority parameters preset for the camping scene are obtained.

[0166] In some embodiments, the power supply scenario may also be determined by identifying the type of power-consuming device corresponding to the power supply port in a valid state.

[0167] Schematically, the energy storage power supply device includes power supply ports 1 to 5, wherein power supply port 1 is used to power a camping light, power supply port 2 is used to power a grill, power supply port 3 is used to power a computer, etc. When it is detected that power supply ports 1 and 2 are connected to useful electrical devices and are in an effective state, it is determined that the energy storage power supply device is in a camping scene.

[0168] It is worth noting that the above-mentioned method of identifying the power supply scenario is only an illustrative example and is not limited to this in the embodiments of the present application.

[0169] The second method is to obtain a priority parameter in response to receiving a priority configuration operation for the power supply port.

[0170] Optionally, the priority configuration operation may be a configuration operation for a physical button, a configuration operation for an interface control, or a voice configuration operation for an energy storage power supply device, which is not limited in the embodiments of the present application.

[0171] Illustratively, the priority configuration operation may be received through a control interface of the energy storage power supply device, or through a priority button for a power supply port in the energy storage power supply device, which is not limited in this embodiment of the present application.

[0172] The control interface may be a program interface of an application program in a terminal for controlling the energy storage power supply device, or may be a control panel interface on the energy storage power supply device.

[0173] The third type is to automatically determine the priority parameters based on the real-time power supply conditions of multiple power supply ports.

[0174] The real-time power supply status includes but is not limited to the power supply mode currently used by the power supply port, power supply duration, power output power, etc.

[0175] Illustratively, taking the real-time power supply situation including the power supply mode as an example, the power supply mode of the power supply port for the power-consuming device is automatically identified, and the power supply modes include plug-in power supply mode and charging power supply mode; the priority parameter corresponding to the power supply port is automatically determined based on the power supply mode.

[0176] Among them, the power output priority corresponding to the power supply port using the plug-in power supply mode is higher than the power output priority corresponding to the power supply port using the charging power supply mode.

[0177] The plug-in power supply mode is used to use the electric energy output from the power supply port to immediately maintain the operation of the electrical equipment, and the charging power supply mode is used to store the electric energy output from the power supply port in the electrical equipment.

[0178] Optionally, the power supply mode corresponding to the power supply port can be dynamically converted.

[0179] In schematic form, plug-in power supply is adopted for plug-in type electrical equipment, charging power supply is adopted for rechargeable type electrical equipment, and a combination of plug-in power supply and charging power supply can be adopted for hybrid type electrical equipment, wherein plug-in type electrical equipment is electrical equipment which consumes electric energy immediately to maintain operation and does not have the ability to store electric energy, such as plug-in type desk lamps, etc., rechargeable type electrical equipment is electrical equipment which has the ability to store electric energy, such as energy storage batteries, etc., and hybrid type electrical equipment is electrical equipment which can consume electric energy in time to maintain operation and has the ability to store electric energy, such as lamps with rechargeable batteries, etc.

[0180] For hybrid electrical equipment, you can first use the plug-in power supply method, and then use the charging power supply method when the equipment is turned off (that is, not in working state). You can also first use the charging power supply method, and then use the plug-in power supply method when the equipment energy storage is completed or the energy storage reaches a preset power threshold.

[0181] It is worth noting that the above-mentioned power supply methods are only illustrative examples and are not limited to this in the embodiments of the present application.

[0182] The method provided in the embodiment of the present application can improve the automation and flexibility of determining the priority parameters by automatically determining the priority parameters based on the real-time power supply conditions of multiple power supply ports. By automatically determining the priority parameters corresponding to the power supply ports based on the power supply mode, the power output priority corresponding to the power supply ports using the plug-in power supply mode is higher than the power output priority corresponding to the power supply ports using the charging power supply mode. When the energy storage power supply device reduces the effective power supply ports based on the remaining power supply capacity, the power supply ports using the charging power supply mode can be closed first, ensuring that the plug-in devices can work normally and improving the power supply efficiency.

[0183] In some embodiments, for a power supply port that adopts a charging power supply mode, the charging time of the power supply port is recorded; a priority parameter corresponding to the power supply port is determined based on the charging time, and the power output priority indicated by the priority parameter is negatively correlated with the charging time.

[0184] Illustratively, a first priority parameter is preset for a power supply port that adopts a charging power supply mode, and the charging time of the power supply port is recorded. When the charging time reaches the first preset time, the priority parameter of the power supply port is updated to a second priority parameter. When the charging time reaches the second preset time, the priority parameter of the power supply port is updated to a third priority parameter, wherein the first preset time is less than the second preset time, the power output priority indicated by the first priority parameter is higher than the second priority parameter, and the power output priority indicated by the second priority parameter is higher than the third priority parameter.

[0185] The method provided in the embodiment of the present application, for power supply ports that adopt a charging power supply mode, can determine the priority parameter based on the charging time, so that when the energy storage power supply device closes the power supply port based on the remaining power supply capacity, the power supply port with a longer charging time can be closed first. Since the longer the charging time, the more power reserve the power-consuming device has, the priority closure of the power supply port corresponding to the power-consuming device can minimize the impact on the power-consuming device and improve the power supply efficiency.

[0186] In some embodiments, for a power supply port that adopts a charging power supply mode, the battery power of the power-consuming device is obtained; based on the battery power, a priority parameter corresponding to the power supply port is determined, and the power output priority indicated by the priority parameter is negatively correlated with the battery power.

[0187] Illustratively, for a power supply port that adopts a charging power supply mode, the battery power of the power-consuming device is obtained, and when the battery power is in a first power range, the priority parameter of the power supply port is determined to be a fourth priority parameter, and when the battery power is in a second power range, the priority parameter of the power supply port is determined to be a fifth priority parameter, wherein the power value corresponding to the first power range is lower than that of the second power range, and the power output priority indicated by the fourth priority parameter is higher than that of the fifth priority parameter.

[0188] The method provided in the embodiment of the present application, for a power supply port that adopts a charging power supply mode, determines the priority parameter of the power supply port based on the battery power of the power-consuming device, so that when the energy storage power supply device closes the power supply port based on the remaining power supply capacity, the power supply port corresponding to the power-consuming device with a larger battery power is preferentially closed, thereby reducing the impact on the power-consuming device and concentrating the power supply to plug-in devices or devices with less battery power, thereby improving the power supply efficiency.

[0189] The second step is to control nm power supply ports to be in an invalid state.

[0190] Optionally, the multiple power supply ports are respectively connected in series with power supply switches, and the power supply switches are used to control the power supply status of the power supply ports.

[0191] The power supply state includes a valid state and an invalid state.

[0192] In some embodiments, controlling the nm power supply ports to be in an invalid state includes switching power supply switches respectively corresponding to the nm power supply ports from a connected state to a disconnected state.

[0193] When the power switch is in the disconnected state, the power port is in an invalid state; when the power switch is in the connected state, the power port is in a valid state.

[0194] The disconnected state of the power supply state includes that the power supply circuit in the energy storage power supply device is disconnected from the power supply port, and the connected state includes that the power supply amount in the energy storage power supply device is connected to the power supply port.

[0195] Optionally, the power supply port includes at least one of an AC power supply port and a DC power supply port. Different power supply switch control methods may be used for different types of power supply ports.

[0196] Schematically, the power supply port includes an AC power supply port, which corresponds to a neutral wire, a live wire and a ground wire. The AC power supply port can be put into an invalid state by disconnecting the connection between the power switch and at least one of the neutral wire and the live wire.

[0197] Optionally, the power switch corresponding to the AC power supply port is controlled to disconnect the connection with the neutral line; or, the power switch corresponding to the AC power supply port is controlled to disconnect the connection with the live line; or, the power switch corresponding to the AC power supply port is controlled to disconnect the connection with the neutral line and the live line.

[0198] For illustration, please refer to Figure 5 , Figure 5 is a schematic diagram of a single-stage switch control of an AC port provided by an exemplary embodiment of the present application, such as Figure 5 As shown, the energy storage power supply device 500 corresponds to AC output ports (power supply ports) 1 to n, and multiple AC output ports are respectively connected in series with single-stage switches (relays) 1 to n, and each power supply port corresponds to a neutral line (Neutral, N), a live line (Live, L) and a protective earth (PE), and the single-stage switch is used to connect the live line corresponding to the power supply port. When the power parameter is in the second parameter range, the power supply switches corresponding to the nm power supply ports can be controlled to disconnect the connection relationship with the live line, so that the corresponding power supply ports are in an invalid state.

[0199] In some embodiments, the AC power supply port includes a three-phase AC output port, and the live wires corresponding to the three-phase AC output port include U, V, and W three-phase wires. The power supply port can be put into an invalid state by disconnecting the connection between the power supply switch and the U, V, and W three-phase wires.

[0200] Schematically, the power supply port includes a DC power supply port, which has a positive pole and a negative pole. The DC power supply port can be put into an invalid state by disconnecting the connection between the power supply switch and at least one of the positive pole and the negative pole.

[0201] Optionally, control the connection relationship between the power supply switch corresponding to the DC power supply port and the positive pole; or control the connection relationship between the power supply switch corresponding to the DC power supply port and the negative pole; or control the connection relationship between the power supply switch corresponding to the DC power supply port and the positive pole and the negative pole.

[0202] For illustration, please refer to Figure 6 , Figure 6 is a schematic diagram of a single-stage switch control of a DC port provided by an exemplary embodiment of the present application, such as Figure 6 As shown, the energy storage power supply device 600 corresponds to DC output ports (power supply ports) 1 to n, and the multiple DC output ports are respectively connected in series with single-pole switches (relays) 1 to n, each power supply port corresponds to a positive pole (DC+) and a negative pole (DC-), and the single-pole switch is used to connect the positive pole corresponding to the power supply port. When the power parameter is in the second parameter interval, the power supply switches corresponding to the nm power supply ports can be controlled to disconnect the connection relationship with the positive pole, so that the corresponding power supply ports are in an invalid state.

[0203] To sum up, the method provided in the embodiment of the present application improves the control flexibility of the energy storage power supply equipment by enabling the energy storage power supply equipment to prioritize closing the power supply port with a lower power output priority when closing the power supply port based on the remaining power supply capacity according to the priority parameters. It can ensure the power supply to important electrical equipment by adjusting the priority parameters and improve the power supply efficiency.

[0204] In some embodiments, when the energy storage power supply device is supplying power to multiple electrical devices at the same time, the device may overheat, and the output power needs to be reduced to protect the device from damage caused by excessive temperature. Specifically, the output power can be reduced by reducing the number of power supply ports in an effective state to achieve the over-temperature load reduction function.

[0205] For illustration, please refer to Figure 7 , which shows a flow chart of a control method for an energy storage power supply device provided by an exemplary embodiment of the present application. The method can be executed by a terminal, or by a server, or by both a terminal and a server. The present application embodiment takes the method executed by a terminal as an example for explanation. Figure 7 As shown, the method comprises the following steps:

[0206] Step 710: Acquire temperature parameters of the energy storage power supply device.

[0207] The temperature parameter is used to characterize the equipment temperature of the energy storage power supply equipment.

[0208] Optionally, the temperature parameter includes but is not limited to at least one of the overall internal temperature of the energy storage power supply device, the battery temperature of the energy storage power supply device, the inverter device temperature of the energy storage power supply device, etc.

[0209] Among them, the inverter device is used to convert direct current into alternating current, so that the power supply port can output alternating current to the power-consuming equipment.

[0210] Equipment components such as equipment batteries and inverter devices tend to generate heat when the energy storage power supply equipment is working. If the temperature is too high, it will easily affect the performance of the components and may also cause safety problems. Therefore, it is necessary to detect temperature parameters in real time and take cooling measures in time.

[0211] Step 720: When the temperature parameter does not meet the over-temperature load reduction condition, control a power supply ports among the multiple power supply ports to be in a valid state, where a is a positive integer.

[0212] The over-temperature load reduction condition is used to indicate that when the temperature of the equipment is too high, the load of the energy storage power supply equipment is reduced to achieve a cooling effect.

[0213] Optionally, the over-temperature load reduction condition includes the device temperature rising to a preset temperature threshold.

[0214] When the temperature parameter does not meet the over-temperature load reduction condition, the power supply port in the multiple power supply ports is maintained in a valid state.

[0215] Step 730: When the temperature parameter meets the over-temperature load reduction condition, control b power supply ports among the multiple power supply ports to be in a valid state, where b is a positive integer.

[0216] Among them, a is greater than b.

[0217] By reducing the number of power supply ports in an effective state and reducing the load of the energy storage power supply equipment when the temperature parameters meet the over-temperature load reduction conditions, an over-temperature load reduction protection mechanism is implemented.

[0218] Schematically, when the temperature parameters do not meet the over-temperature load reduction conditions, a power supply ports among the multiple power supply ports are controlled to be in an effective state. When the temperature parameters meet the over-temperature load reduction conditions, the number of power supply ports in the effective state is controlled to decrease from a to b.

[0219] Among them, the b power supply ports in a valid state may include some of the a power supply ports mentioned above, and may also include other power supply ports different from the a power supply ports, which is not limited in this embodiment of the present application.

[0220] Taking keeping b power ports out of a power ports in a valid state as an example, step 730 includes, when the temperature parameters meet the over-temperature load reduction conditions, controlling ab power ports out of a power ports to be in an invalid state, and the invalid state is used to indicate that the power port does not have the ability to output electrical energy.

[0221] Among them, controlling ab power supply ports among a power supply ports to be in an invalid state means switching ab power supply ports among a power supply ports from a valid state to an invalid state, and the states of other power supply ports (including the above-mentioned b power supply ports, and power supply ports among multiple power supply ports except the above-mentioned a power supply port) remain unchanged.

[0222] Optionally, the ab power supply ports are controlled to be in an invalid state through a power supply switch.

[0223] Illustratively, when the temperature parameter meets the over-temperature load reduction condition, the power supply switches corresponding to the ab power supply ports are controlled to be in an off state.

[0224] Optionally, the ab power supply ports may be determined randomly, or may be selected based on a selection operation, or may be determined according to priority parameters corresponding to the power supply ports.

[0225] The priority parameter is used to indicate the power output priority of the power supply port.

[0226] Illustratively, ab power supply ports are determined from a power supply ports according to the priority parameter, and the ab power supply ports are controlled to be in an invalid state, wherein the power output priority corresponding to the ab power supply ports is lower than that of the b power supply ports.

[0227] The control order of the power supply port based on the power quantity parameter being in an invalid state and the duration of the power supply port being in a valid state based on the power quantity parameter are related to the power output priority corresponding to the power supply port.

[0228] Indicatively, when the temperature parameter meets the over-temperature load reduction condition, the power supply port with a higher power output priority is preferentially kept in a valid state, that is, the power supply port with a lower power output priority is preferentially controlled to be in an invalid state.

[0229] Taking a fixed preset temperature threshold as an example, when the device temperature rises to the preset temperature threshold for the i-th time, the power supply port corresponding to the i-th priority parameter is controlled to be in an invalid state, where i is a positive integer, and the priority parameters corresponding to multiple power supply ports are arranged in order from low to high according to the power output priority.

[0230] Taking multiple increasing preset temperature thresholds as an example, when the device temperature rises to the jth preset temperature threshold, the power supply port corresponding to the jth priority parameter is controlled to be in an invalid state, where j is a positive integer, and the priority parameters corresponding to the multiple power supply ports are arranged in order from low to high according to the power output priority.

[0231] For illustration, please refer to Figure 8 , Figure 8is a schematic diagram of an over-temperature load reduction process provided by an exemplary embodiment of the present application, such as Figure 8 As shown, for the over-temperature load reduction protection mechanism of the energy storage power supply equipment, step 810 is executed in sequence, and the user configures the power usage priority parameters or the factory default parameters; step 820, the user starts to use electricity and monitors the power consumption; step 830, determines whether the over-temperature load reduction is required, and if so, executes step 840 to close the power supply port with the lowest priority; when the power supply port with the lowest priority has been closed, step 850 is executed to determine whether the over-temperature load reduction is required, and if so, step 860 is executed to close the power supply port with the second lowest priority; when the power supply port with the second lowest priority has been closed, step 870 is executed to determine whether the over-temperature load reduction is required, and if so, step 880 is executed to close the power supply port with a lower priority; when the power supply port with a lower priority has been closed, step 890 is executed to determine whether the over-temperature load reduction (over-temperature shutdown) is required, and if so, step 801 is executed to shut down.

[0232] To summarize, the method provided in the embodiment of the present application reduces the number of power supply ports in an effective state and reduces the load of the energy storage power supply equipment when the temperature parameters meet the over-temperature load reduction conditions, thereby realizing an over-temperature load reduction protection mechanism, and can reduce the number of power supply ports in an effective state according to priority parameters, reduce the impact on power supply ports with higher power output priority, and improve power supply efficiency.

[0233] In some embodiments, the control method of the energy storage power supply equipment provided in the embodiments of the present application determines the power output priority of multiple power supply ports by presetting priority parameters, or configuring priority parameters through LCD interface buttons or remote control applications of the portable mobile power supply, or automatically determining priority parameters according to the real-time power supply status of the power supply ports, thereby flexibly controlling the power supply status of multiple power supply ports according to the remaining power supply capacity and the over-temperature load reduction protection mechanism to ensure power supply to the highest priority load.

[0234] The method provided in the embodiment of the present application is an effective power management mechanism: by respectively setting switch modules on the lines of multiple AC jacks and DC jacks, and controlling the power-on of corresponding AC and DC jacks according to the battery power of the outdoor power supply, an effective power management mechanism is implemented, which can not only prevent users from using the outdoor power supply without restraint, causing the power supply to be exhausted under unexpected circumstances, but also effectively protect the battery of the outdoor power supply and extend its service life.

[0235] The method provided in the embodiment of the present application can intelligently allocate and manage the use of electricity according to the urgency or importance of electrical appliances. For example, when the outdoor power supply is insufficient, some low-priority AC and DC sockets can be turned off to ensure that high-priority electrical appliances can be supplied with electricity in a timely manner, thereby ensuring normal use by users, realizing intelligent power allocation and management, improving the use efficiency and safety of outdoor power products, and enhancing the user experience.

[0236] The method provided in the embodiment of the present application can flexibly select which electrical appliances to use according to the actual needs of the user by setting multiple AC jacks and DC jacks and setting switch modules respectively. At the same time, through intelligent power distribution and management, it can ensure that the user can obtain the required power in time during outdoor activities, thereby improving the user's experience.

[0237] The method provided in the embodiment of the present application is not only applicable to outdoor power products in outdoor activities such as camping and traveling, but can also be applied to other occasions requiring mobile power, such as outdoor work, emergency rescue, etc. Its wide range of applications increases its market value and potential for use.

[0238] Fig. 9 is a structural block diagram of a control device for energy storage power supply equipment provided by an exemplary embodiment of the present application, such as Fig. 9 As shown, the device includes the following parts:

[0239] An acquisition module 910 is used to acquire a power parameter of the energy storage power supply device, where the power parameter is used to characterize the remaining power supply capacity of the energy storage power supply device, where the energy storage power supply device includes a plurality of power supply ports, and the power supply ports are used to output power to the power-consuming device;

[0240] A control module 920, configured to control n power supply ports of the plurality of power supply ports to be in a valid state when the power parameter is in a first parameter interval, wherein the valid state is used to indicate that the power supply port has the ability to output electric energy, and n is a positive integer;
