Technical Field

[0001] The present application relates to the technical field of energy storage technology, and in particular to an energy distribution method, device and electronic equipment for a combined energy storage system. Background Art

[0002] In modern society, the stability and continuity of power supply are essential for the normal operation of various devices. However, traditional power supply systems often face many challenges, such as imbalance between supply and demand, peak power load, etc. These problems not only lead to reduced operating efficiency of the power system, but may also cause damage to terminal equipment. In response to these problems, combined energy storage systems have been increasingly widely used. These devices can store energy during periods of low power demand and release energy during periods of high power demand, thereby balancing power supply and demand and alleviating peak power loads.

[0003] However, in actual applications, the operation of the combined energy storage system is not without problems. The power supply strategy in the combined energy storage system adopts a one-to-one approach, that is, one energy storage device in the combined energy storage system corresponds to one terminal device, which means that when the power of the energy storage device is insufficient, it will not be able to supply power to the corresponding terminal device, thereby failing to meet the power demand of the terminal device.

[0004] Therefore, there is an urgent need for an energy distribution method, device and electronic equipment for a combined energy storage system. Summary of the invention

[0005] The present application provides an energy distribution method, device and electronic equipment for a combined energy storage system, which facilitates energy distribution to meet the power demand of terminal equipment.

[0006] In a first aspect of the present application, a method for distributing energy for a combined energy storage system is provided, the method comprising: receiving a load demand sent by a terminal device, the load demand comprising power consumption, the load demand being used to represent the power consumption demand required by the terminal device; obtaining operating parameters of a first energy storage device, the operating parameters comprising a current temperature and a remaining power, the combined energy storage system comprising a plurality of energy storage devices, the first energy storage device being an energy storage device among the plurality of energy storage devices that supplies power to the terminal device; calculating an output power according to the current temperature and the remaining power; and if the output power is less than the power consumption, sending a power supply instruction to a second energy storage device to control the second energy storage device to supply power to the terminal device, the second energy storage device being any one of the plurality of energy storage devices except the first energy storage device.

[0007] By adopting the above technical solution, by receiving the load demand sent by the terminal device, it is convenient to know the power consumption required by the terminal device. Next, by obtaining the operating parameters of the first energy storage device corresponding to the terminal device, the current temperature and the remaining power of the first energy storage device are known, so as to calculate the output power of the first energy storage device according to the current temperature and the remaining power. When the output power is less than the power consumption, a power supply instruction will be sent to the second energy storage device to control the second energy storage device to supply power to the terminal device. Therefore, when the first energy storage device cannot meet the power consumption required by the terminal device, a power supply instruction is sent to the second energy storage device to control the second energy storage device to supply power to the terminal device, so as to facilitate energy distribution to meet the power demand of the terminal device.

[0008] Optionally, the output power is calculated according to the current temperature and the remaining power, and is specifically calculated by the following formula:

[0009] ;

[0010] Among them, P is the output power, P0 is the remaining power, T i is the ith temperature value, P i is the output power corresponding to the ith temperature value, T0 is the reference temperature, and T is the current temperature.

[0011] By adopting the above technical solution, the formula incorporates temperature parameters, and by using a comparison between the reference temperature and the current temperature, the performance changes of the energy storage device can be better understood or predicted. This comparison can help the device maintain a stable power output under various temperature conditions, which helps to ensure the reasonable distribution of power among the energy storage devices, thereby preventing any device from being overloaded or underpowered. Using this formula, power distribution can be continuously optimized to improve the efficiency and stability of the entire energy storage system. At the same time, it also helps prevent system failures and improve the reliability and availability of the system. By accurately predicting and controlling power output, this formula helps to improve the efficiency of energy use and thus reduce energy waste.

[0012] Optionally, obtaining the operating parameters of the first energy storage device specifically includes: receiving an operating parameter data packet sent by a sensor group, wherein the sensor group is used to measure the operating parameter data of the first energy storage device; preprocessing the operating parameter data packet to obtain the operating parameters of the first energy storage device, wherein the preprocessing includes data cleaning, data classification and normalization.

[0013] By adopting the above technical solution, accurate and real-time data can be obtained by measuring the operating parameter data of the first energy storage device using a sensor group. The data cleaning process can help remove outliers or erroneous data and improve the accuracy of the data. Data classification and normalization processing can classify and standardize different operating parameter data packets to make them easier to analyze and use. This ensures that the data is consistent and comparable when used. Through real-time monitoring and preprocessing of operating parameters, potential problems can be discovered and solved in a timely manner to ensure the stable operation of the combined energy storage system. Through accurate measurement and real-time monitoring of operating parameters, the performance of energy storage equipment can be better understood and the efficiency of energy use can be further optimized. Obtaining accurate operating parameters is very important for the maintenance and management of equipment. These data can help predict possible problems with the equipment and take corresponding measures in advance to prevent or repair them.

[0014] Optionally, before sending a power supply instruction to the second energy storage device, the method also includes: judging the operating state of the second energy storage device, the operating state including an idle state, a charging state and a discharging state; if the second energy storage device is in an idle state, determining that the second energy storage device is a power supply device for the terminal device.

[0015] By adopting the above technical solution, by judging the operating status of the second energy storage device, it is possible to avoid sending power supply instructions to devices that are not ready to power supply, which helps to protect the performance and life of the equipment, thereby improving the efficiency of the combined energy storage system. By confirming that the second energy storage device is in an idle state, it can be ensured that the selected power supply device is ready to power the terminal device, thereby ensuring that the terminal device has a stable power supply. By monitoring and managing the operating status of each energy storage device, the energy in the entire combined energy storage system can be more effectively deployed and managed, and the energy utilization efficiency can be improved. By monitoring the operating status of the energy storage device in real time, potential problems can be discovered and resolved in a timely manner, and corresponding adjustments can be made to ensure the stable and reliable operation of the entire combined energy storage system.

[0016] Optionally, if the second energy storage device is in a charging state, a charging and discharging time interval of the second energy storage device is obtained; and according to the charging and discharging time interval, a time for sending the power supply instruction to the second energy storage device is determined.

[0017] By adopting the above technical solution, by obtaining the charging and discharging time interval of the second energy storage device, its charging and discharging behavior can be better understood, thereby helping to adjust and manage the charging and discharging process, which helps to ensure the charging and discharging efficiency and life of the equipment. By determining the sending time of the power supply instruction according to the charging and discharging time interval, the power supply can be more reasonably scheduled and allocated, thereby ensuring that the charging and discharging process of each energy storage device matches the power demand. Through sophisticated charging and discharging management and power supply scheduling, the stability of the entire joint energy storage system can be improved, ensuring that a stable power supply can be provided to the terminal device under various circumstances. By monitoring and adjusting the charging and discharging time intervals of each energy storage device, energy can be managed and used more effectively and the efficiency of energy use can be improved. By real-time monitoring of the charging and discharging status of the second energy storage device, problems in the charging and discharging process can be discovered in a timely manner, and corresponding preventive maintenance measures can be taken to ensure the stable operation of the equipment.

[0018] Optionally, the combined energy storage system further includes a charging device, and after sending a power supply instruction to the second energy storage device if the output power is less than the power consumption, the method further includes: sending a charging instruction to the charging device to control the charging device to charge the first energy storage device.

[0019] By adopting the above technical solution and introducing charging equipment, the combined energy storage system can be more complete and effective in energy management. The charging equipment can charge the first energy storage device to ensure that its power is replenished in time, thereby maintaining the stable operation of the entire combined energy storage system. By controlling the charging device to charge the first energy storage device, renewable energy or excess electricity can be stored at the appropriate time to further optimize the use and management of energy. The combined energy storage system includes a variety of energy storage devices and charging devices, making the system more flexible and reliable in responding to various energy needs and changes. By controlling the charging device to charge the first energy storage device, the performance and life of the first energy storage device can be protected to avoid exhaustion or overuse of its power. By simultaneously monitoring and managing the status and operating parameters of multiple energy storage devices and charging devices, the power supply can be more reasonably dispatched and allocated, providing more stable, reliable and efficient power services for terminal devices.

[0020] Optionally, if the output power is greater than or equal to the power consumption, a power supply instruction is sent to the first energy storage device to control the first energy storage device to supply power to the terminal device.

[0021] By adopting the above technical solution, when the output power meets or exceeds the power demand, a power supply instruction is directly sent to the first energy storage device, which can make more efficient use of existing energy and avoid unnecessary energy conversion or transmission losses. By giving priority to the first energy storage device for power supply, the performance and life of the second energy storage device can be protected, and its unnecessary charge and discharge cycles can be avoided. By adjusting the power supply source according to the actual power demand, the stability of the entire joint energy storage system can be enhanced to ensure that a stable power supply can be provided to the terminal device under different load demand conditions. According to the comparison results of power consumption and output power, dynamically adjusting the target energy storage device of the power supply instruction can help achieve a more optimized and dynamic energy management strategy. By real-time monitoring and comparison of power demand and output power, the power supply can be quickly responded to and adjusted to meet the changing power needs of the terminal equipment.

Next, by obtaining the operating parameters of the first energy storage device corresponding to the terminal device, the current temperature and the remaining power of the first energy storage device are known, so as to calculate the output power of the first energy storage device according to the current temperature and the remaining power. When the output power is less than the power consumption, a power supply instruction will be sent to the second energy storage device to control the second energy storage device to supply power to the terminal device. Therefore, when the first energy storage device cannot meet the power consumption required by the terminal device, a power supply instruction is sent to the second energy storage device to control the second energy storage device to supply power to the terminal device, so as to realize energy distribution and meet the power demand of the terminal device;

[0033] In order to enable technicians in this field to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0034] In the description of the embodiments of the present application, words such as "for example" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "for example" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "for example" or "for example" is intended to present related concepts in a specific way.

[0035] In the description of the embodiments of the present application, the meaning of the term "multiple" refers to two or more. For example, multiple systems refer to two or more systems, and multiple screen terminals refer to two or more screen terminals. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. The terms "include", "comprise", "have" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0036] In modern society, the stability and continuity of power supply are essential for the normal operation of various devices. However, traditional power supply systems often face many major challenges, such as imbalance between supply and demand and peak load of electricity. These problems not only lead to reduced operating efficiency of the power system, but may also cause damage to terminal equipment. In order to solve these problems, combined energy storage systems are becoming more and more widely used. These systems can store energy during periods of low power demand and release energy during periods of high power demand, thereby balancing power supply and demand and alleviating peak load of electricity.

[0037] However, the combined energy storage system is not without problems in practical applications. The power supply strategy of the combined energy storage system adopts a one-to-one approach, that is, one energy storage device in the combined energy storage system corresponds to one terminal device. This one-to-one power supply mode has some potential problems. First, when the power of the energy storage device is insufficient, it will not be able to supply power to the corresponding terminal device, thereby failing to meet the power demand of the terminal device. This may cause the terminal device to fail to operate normally, or even shut down or be damaged, making it difficult to meet the rapidly changing power demand.

[0038] In order to solve the above technical problems, the present application provides an energy distribution method for a combined energy storage system, referring to Figure 1 , Figure 1 A schematic flow chart of an energy allocation method for a combined energy storage system provided in an embodiment of the present application. The energy allocation method is applied to a management platform in a combined energy storage system, and the method includes steps S110 to S140, which are as follows:

[0039] S110. Receive a load demand sent by a terminal device, where the load demand includes power consumption, and the load demand is used to indicate the power consumption demand of the terminal device.

[0040] Specifically, the management platform will first receive the load demand sent by the terminal device, and the receiving process is real-time. Among them, the management platform is used to manage and monitor the use of energy. It can coordinate and adjust the supply and demand of energy to ensure the stability and efficiency of the joint energy storage system. Terminal devices refer to various devices that require electricity to work, such as computers, mobile phones, electrical appliances, etc. Load demand means the terminal device's expectation of power demand. This demand may be caused by the workload of the device, such as a running computer or TV, or a specific task, such as starting a high-power device.

[0041] For example, assume that a combined energy storage system includes solar panels, batteries, and wind turbines. In this system, the user's mobile phone, as a terminal device, sends its load demand to the management platform, so that the management platform knows that the terminal device is running an application that requires a lot of power, or it is about to perform a power-consuming operation, such as starting a video.

[0042] S120. Obtain operating parameters of a first energy storage device, where the operating parameters include a current temperature and a remaining power. The combined energy storage system includes a plurality of energy storage devices, and the first energy storage device is an energy storage device that supplies power to the terminal device among the plurality of energy storage devices.

[0043] Specifically, after receiving the load demand sent by the terminal device, according to the preset correspondence between the terminal device and the energy storage device, the management platform can learn that the energy storage device corresponding to the terminal device is the first energy storage device. Next, the management platform will obtain the operating parameters of the first energy storage device, thereby learning the current temperature and remaining power of the first energy storage device. Among them, the operating parameters refer to the state parameters of the first energy storage device, including the current temperature and remaining power. The current temperature can indicate the internal temperature of an energy storage device such as a battery or capacitor, and the remaining power indicates the remaining power in the energy storage device, which is used to understand how long the device can continue to supply power. The energy storage system is composed of multiple energy storage devices, and the multiple energy storage devices can be batteries, supercapacitors, fuel cells, solar panels, etc.

[0044] Further, the operating parameters may also include the charge and discharge state, indicating whether the energy storage device is charging or discharging, which is very important for understanding the current power state of the energy storage device and predicting its future power supply capacity; the charge and discharge efficiency, indicating the efficiency of the device charging or discharging, which can help optimize the management of power supply and demand; the number of charge and discharge times, indicating the number of times the device has been charged or discharged, which can help understand the life and performance degradation of the device; the maximum charge and discharge power, indicating the maximum power that the device can charge or discharge, which can help optimize the management of power supply and demand; the running time, indicating the time the device has been running, which can help understand the efficiency and life of the energy storage device; environmental factors, such as ambient temperature, ambient humidity, and pressure, which can affect the performance and life of the energy storage device. It should be noted that the embodiment of the present application focuses on the current temperature of the energy storage device, and other parameters are not limited and will not be repeated here. Obtaining these operating parameters can help the management platform better understand the state of the first energy storage device so as to more effectively manage energy. For example, if the management platform learns that the temperature of a device is too high, it may need to take measures to reduce the temperature to prevent the device from overheating and reducing its performance. At the same time, by understanding the remaining power, the energy management platform can better predict and manage power supply to ensure that terminal devices receive a stable power supply.

[0045] In a possible implementation, obtaining the operating parameters of the first energy storage device specifically includes: receiving an operating parameter data packet sent by a sensor group, the sensor group being used to measure the operating parameter data of the first energy storage device; preprocessing the operating parameter data packet to obtain the operating parameters of the first energy storage device, the preprocessing including data cleaning, data classification and normalization.

[0046] Specifically, the above process is a specific process for a management platform provided in an embodiment of the present application to obtain the operating parameters of the first energy storage device. The management platform receives an operating parameter data packet sent by the sensor group, which means that the management platform receives an operating parameter data packet sent from the sensor group in some way, which may be a network connection, a physical interface, etc. These data packets contain operating parameter information about the first energy storage device, such as the current temperature, remaining power, etc. However, these data packets may be sent in different formats, such as JSON, XML, etc., or sent with different protocols, such as Modbus, Zigbee, etc., depending on the communication protocol between the sensor group and the management platform. These data packets can be sent periodically or on demand, depending on the configuration and working mode of the sensor group and the energy management platform. Among them, the sensor group includes multiple sensors, which may include temperature sensors, current and voltage sensors, etc.

[0047] Next, the management platform will clean, classify and normalize the operating parameter data packets. Data cleaning may include removing outliers, filling missing values, and eliminating noise to ensure the accuracy and completeness of the data. Data classification is to group data according to certain standards, such as type, device, etc., to facilitate subsequent analysis and processing. Normalization is to convert data of different types or ranges into a unified numerical value or proportional relationship to facilitate subsequent comparison and analysis.

[0048] S130: Calculate the output power according to the current temperature and the remaining power.

[0049] Specifically, after obtaining the operating parameters of the first energy storage device, the management platform can calculate the output power according to the current temperature and the remaining power in the operating parameters. The specific calculation method is to use the current temperature and the remaining power as independent variables and the output power as the dependent variable. Because the temperature will affect the output power of the energy storage device, the remaining power and the output power are different.

[0050] In a possible implementation, the output power is calculated according to the current temperature and the remaining power, and is specifically calculated by the following formula:

[0051] ;

[0052] Among them, P is the output power, P0 is the remaining power, T i is the ith temperature value, P i is the output power corresponding to the ith temperature value, T0 is the reference temperature, and T is the current temperature.

[0053] Specifically, the above process is a method for calculating the output power provided by an embodiment of the present application. Among them, the reference temperature is a temperature value preset by the management personnel of the management platform in order to reduce the impact of temperature on the output power, so as to achieve the ideal output power of the energy storage device, such as 25 degrees Celsius. In order to measure the specific percentage of the impact of temperature on the output power, the formula introduces the relationship between different output powers corresponding to multiple different temperature values, which can continuously optimize the power distribution and improve the efficiency and stability of the entire joint energy storage system. The formula incorporates the temperature parameter, and by comparing the reference temperature with the current temperature, the performance changes of the energy storage device can be better understood or predicted. This comparison can help the device maintain a stable power output under various temperature conditions, which helps to ensure the reasonable distribution of power among the energy storage devices, thereby preventing any device from being overloaded or underpowered. At the same time, it also helps to prevent system failures and improve the reliability and availability of the system. By accurately predicting and controlling power output, this formula helps to improve the efficiency of energy use and thus reduce energy waste.

[0054] S140: If the output power is less than the power consumption, a power supply instruction is sent to a second energy storage device to control the second energy storage device to supply power to the terminal device. The second energy storage device is any one of the multiple energy storage devices except the first energy storage device.

[0055] Specifically, when the output power is less than the power consumption, that is, the first energy storage device corresponding to the current terminal device cannot meet the power demand, therefore, the management platform will send a power supply instruction to the second energy storage device, thereby controlling the second energy storage device to supply power to the terminal device. Among them, the power supply instruction may include the following: target device, that is, the target of the instruction is the second energy storage device. Power supply instructions generally include operations such as starting, stopping or adjusting power supply. The instruction may also include the amount of power supply or the target power so that the second energy storage device knows how much power needs to be provided to the terminal device. The instruction may also include the duration of power supply, that is, how long the second energy storage device needs to provide the specified power supply. The instruction may include instructions on power supply priority, which means that when there are multiple energy storage devices, some devices may need to be powered more preferentially than other devices.

[0056] For example, suppose a combined energy storage system is used for home energy storage, including solar panels, batteries, and supercapacitors as energy storage devices. When the power of the solar panels is not enough to meet the power demand of the home, the management platform can send a power supply instruction to the supercapacitor, instructing it to supply power to the home load. The power supply instruction may include instructing the supercapacitor to supply 100 watts of power for two hours with high priority.

[0057] In a possible implementation, before sending a power supply instruction to the second energy storage device, it also includes: judging the operating state of the second energy storage device, the operating state includes an idle state, a charging state, and a discharging state; if the second energy storage device is in an idle state, determining that the second energy storage device is a power supply device for the terminal device.

[0058] Specifically, before sending a power supply instruction to the second energy storage device, the management platform will also determine the operating status of the second energy storage device. When it is confirmed that the second energy storage device is in an idle state, the second energy storage device will be determined as the power supply device of the terminal device, that is, the second energy storage device defaults to powering the terminal device first. Among them, the idle state means that it is neither being charged nor discharging outward, that is, the power of the second energy storage device has not changed. For example, assume that the combined energy storage system is a home energy system that includes a solar panel, a battery, and a supercapacitor as energy storage devices. If the solar panel is low on power and the battery is discharging to power the load at home, the management platform can determine that the supercapacitor is in an idle state. Then, the management platform can determine the supercapacitor as a device that supplies power to the terminal device, and send a power supply instruction to the supercapacitor to supplement the power supply.

[0059] In a possible implementation, if the second energy storage device is in a charging state, the charging and discharging time interval of the second energy storage device is obtained; and the time for sending a power supply instruction to the second energy storage device is determined according to the charging and discharging time interval.

[0060] Specifically, the charge and discharge time interval refers to the time required for the energy storage device to start charging and be able to discharge. This time interval depends on the type of device and its current state. For example, a battery may take 30 minutes to 1 hour to charge from a fully discharged state to a state where it can supply power, while a supercapacitor can complete charging and start discharging in a shorter time, such as 1 minute to 10 minutes. By understanding the charge and discharge time interval of the second energy storage device, the management platform can determine when it is most appropriate to send a power supply instruction. For example, if the charge and discharge time interval of the second energy storage device is 30 minutes, the energy management platform can send a power supply instruction to it 30 minutes after the second energy storage device completes the last charge. By determining the sending time of the power supply instruction based on the charge and discharge time interval, the power supply can be more reasonably scheduled and allocated, thereby ensuring that the charge and discharge process of each energy storage device matches the power demand. By monitoring and adjusting the charge and discharge time intervals of each energy storage device, energy can be managed and used more effectively and the energy utilization efficiency can be improved. By real-time monitoring of the charge and discharge status of the second energy storage device, problems in the charge and discharge process can be discovered in a timely manner, and corresponding preventive maintenance measures can be taken to ensure the stable operation of the equipment.

[0061] In a possible implementation, the combined energy storage system further includes a charging device. If the output power is less than the power consumption, after sending a power supply instruction to the second energy storage device, the method further includes: sending a charging instruction to the charging device to control the charging device to charge the first energy storage device.

[0062] Specifically, in addition to the energy storage devices involved in the above content, such as batteries and supercapacitors, the combined energy storage system also includes charging devices, such as power adapters or solar charging panels. When the output power is less than the power consumption, it means that the power of the first energy storage device is insufficient and needs to be charged in preparation for power supply again. Therefore, the management platform will send a charging instruction to the charging device. For example, assume that the combined energy storage system is a home energy system that includes solar charging panels, batteries and supercapacitors, and there is also a power adapter as a charging device. When the battery power is not enough to meet the family's power needs and the supercapacitor is already in an idle state, the management platform can send a charging instruction to the power adapter or solar charging panel to start charging the battery. At the same time, the energy management platform will also send a power supply instruction to the supercapacitor to control it to supply power to the home load to ensure that the family's power needs are met. In this way, the energy management platform achieves flexible and efficient management of power supply and demand and energy distribution by coordinating the work of multiple energy storage devices and charging devices.

[0063] In a possible implementation, if the output power is greater than or equal to the power consumption, a power supply instruction is sent to the first energy storage device to control the first energy storage device to supply power to the terminal device.

[0064] Specifically, the output power is greater than or equal to the power consumption, which means that the power of the first energy storage device is sufficient to meet the power demand of the terminal device. Next, the management platform will send a power supply instruction to the first energy storage device. For example, assume that the combined energy storage system is a home energy system including batteries and supercapacitors, and the terminal device is a household appliance. When the power of the solar panels is sufficient to meet the household's power needs, the management platform can send a power supply instruction to the battery to start supplying power to the household appliances.
