[0002] With the rapid development of communications technology, the accelerated deployment of 5G networks and the increasing number of communication base stations, the traditional mains power supply model has exposed significant shortcomings in many scenarios. In remote areas, mains power access is difficult and construction costs are extremely high. In areas prone to natural disasters, mains power outages are prone to severe disruptions, severely impacting base station operations and leading to interruptions in communication services. Furthermore, energy consumption in the communications industry is becoming increasingly severe, with electricity consumption increasing annually and high electricity costs becoming a heavy burden for operators. Against this backdrop, micropower control systems and integrated micropower supplies have emerged. Traditional base station power modules are bulky, have low power density, and are difficult to install and maintain, making them incompatible with the current trend towards distributed and miniaturized base stations. Micropower supplies, with their high efficiency, flexibility, and energy efficiency, can coordinate multiple energy sources—including mains, solar, and wind power. Energy storage units ensure power supply stability and enable precise energy control, meeting the urgent need for reliable, efficient, and green power supply in communication base stations across diverse scenarios. However, their limited space leads to frequent charging and discharging, resulting in unpredictable energy storage battery life.

Therefore, this monitoring device is applicable to the switching power supplies of most communication base stations and has strong adaptability. Moreover, the data collected by the DC voltage acquisition circuit and the mains power information acquisition circuit can be uniformly connected to the FSU through the same controller, requiring only one communication protocol, simplifying development and debugging, and saving manpower and material resources.

[0010] Preferably, the controller is used to divide the micro power supply impact period based on the battery life impact characterization values ​​corresponding to different temperature impact periods. The controller determines that the micro power source impact period is a significant impact period according to a condition that the battery life impact characterization value is greater than or equal to a preset impact characterization value; According to the condition that the battery life impact characterization value is less than the preset impact characterization value, the micro power source impact period is determined to be a weak impact period.

Moreover, the controller distinguishes the micro power influence cycle based on the battery life influence characterization values ​​corresponding to different temperature influence cycles, monitors the energy storage battery, determines whether there is an abnormality in the energy storage effect of the energy storage battery, and determines whether to enable the temperature compensation device. Considering the impact of the life difference of the energy storage battery on the micro power control efficiency during the operation of the micro power control system, the temperature compensation device is adaptively intervened, thereby ensuring the control efficiency and accuracy of the micro power control system.

Moreover, through the changes in charging and discharging parameters, it can accurately analyze the energy storage battery life impact characterization value in different temperature influence cycles, thereby improving the control efficiency of the micro power supply.

[0019] In particular, the present invention can distinguish the micro-power source impact cycles, including significant impact and weak impact cycles, through the energy storage battery life impact characterization values ​​corresponding to different temperature impact cycles, thereby improving energy utilization efficiency.

[0025] See also Figure 1 As shown in FIG, which is a structural block diagram of a micro power supply control system for a communication base station according to an embodiment of the present invention, the present invention provides a micro power supply control system for a communication base station, including: A micro power supply assembly comprising an energy storage battery for storing electrical energy, a backup power supply connected to the energy storage battery for continuously providing electrical energy, and a temperature compensation device for adjusting the temperature of the energy storage battery area; A monitor comprising a plurality of temperature sensors for monitoring the temperature of different areas of the energy storage battery, a duration monitoring unit for monitoring the operating time of the energy storage battery, and an energy monitoring unit for obtaining charge and discharge parameters of the battery in a historical period; an analyzer configured to store historical data monitored by the monitor, identify temperature impact cycles based on the difference between the average temperature of the energy storage battery area in different historical cycles and a predetermined temperature threshold, and analyze the battery life impact characterization value of the energy storage battery in different temperature impact cycles based on the charge and discharge parameters; A controller is connected to the micro power source component, the monitor, and the analyzer, respectively, and is used to divide the micro power source impact cycle based on the battery life impact characterization values ​​corresponding to different temperature impact cycles, and monitor the operating status of the micro power source based on the division results of the micro power source impact cycle. For a weak impact period condition, determining whether the energy storage battery has an abnormality based on the difference between the battery life impact characteristic value of the energy storage battery area within the predetermined period and the predetermined battery life impact characteristic value, and if an abnormality is present, determining whether to activate the temperature compensation device; For those that are judged to significantly affect the cycle conditions, whether to enable the backup power supply is determined based on the actual operating time of the energy storage battery; The charge and discharge parameters include charge and discharge times and charge and discharge depth.

[0026] It is understandable that there is no limitation on the method for monitoring the number of charge and discharge times of the energy storage battery. In implementation, the power monitoring unit is connected in series with a hardware counter module in the charging or discharging circuit of the energy storage battery to monitor the number of charge and discharge times of the energy storage battery in a historical period; other forms can also be used, which will not be elaborated here.

[0027] It is understandable that there is no limitation on the monitoring method of the charge and discharge depth of the energy storage battery, and it can be a voltage monitoring method, an ampere-hour integration method, or a coulomb meter method. In implementation, the power monitoring unit uses a special coulomb meter to directly measure the change in charge during the battery charging and discharging process, and obtains the charge and discharge depth by monitoring the amount of electricity charged and discharged by the battery. The charge depth is the ratio of the charged amount to the rated capacity, and the discharge depth is the ratio of the discharged amount to the rated capacity. Other forms can also be used, which will not be elaborated here.

[0028] It is understandable that there is no limitation on the form of the backup power supply. In practice, the backup power supply may be a battery or other forms, which will not be elaborated here.

[0029] Specifically, this system includes an input module, an output module, a rectifier module, a lightning arrester, a micro power supply component, a monitor, an analyzer and a controller. The electric energy is stored through the micro power supply component and the temperature reduction compensation status of the energy storage battery area is changed according to actual conditions. The temperature of the energy storage battery area is monitored by the monitor and the charging and discharging parameters of the energy storage battery are obtained. The analyzer stores the historical data monitored by the monitor to distinguish the micro power influence cycle and determine whether there is an abnormality. Considering the impact of the life difference of the energy storage battery on the micro power control efficiency during the operation of the micro power control system, the temperature compensation device is adaptively intervened to ensure the control efficiency and accuracy of the micro power control system.

[0030] Specifically, the present invention is applied to small base stations and outdoor base stations. Commonly, the micro power supply components include energy storage batteries, which are usually installed and connected to the micro power supply. Due to differences in ambient temperature, the life characteristics of the energy storage batteries vary. In addition, in some cases, there may also be certain differences in different charge and discharge times and charging depths.

[0031] It is understandable that there is no specific limitation on the structure of the monitor, analyzer, controller itself and each unit therein, and they may be composed of logic components, including field programmable processors, computers or microprocessors in computers.

[0032] It is understandable that the form of the temperature compensation device is not limited. It can be a compensation device controlled by a digital signal processor (DSP) or a microcontroller unit (MCU). The temperature compensation device of the micro power supply for the base station can be a simple thermistor to a complex DSP control scheme, which can achieve the temperature compensation function. It can also adopt other forms, which will not be repeated here.

[0033] It is understandable that there is no specific limitation on the location of the temperature sensor, and the temperature sensor can be set in different areas on both sides of the energy storage battery, which will not be described in detail here.

[0034] It is understandable that the power monitoring unit may be a logic component for obtaining information, for example, it may be connected to a battery management system to obtain relevant parameters, which will not be described in detail here.

[0035] See also Figure 2 The above is a logical decision diagram for identifying temperature influence periods in an embodiment of the present invention. The analyzer of the present invention calculates the average temperature of the energy storage battery area in the historical period, and calculates the difference between the average temperature in the historical period and a predetermined temperature threshold. If the difference corresponding to a single historical period is greater than the predetermined difference threshold condition, the historical period is determined to be a temperature influence period.

[0036] Specifically, the difference threshold is obtained in advance, and is determined based on an average difference in temperature obtained in several historical periods, and is set to be between 1.1 times and 1.2 times the average difference.

[0037] Specifically, in order to reflect the detectability of temperature changes and their impact on energy storage batteries, the historical period is selected in the interval [2h, 4h].

[0038] See also Figure 3 As shown, it is a flowchart of the steps of analyzing the battery life impact characterization value of the energy storage battery according to an embodiment of the present invention. The analyzer of the present invention calculates a first difference between the number of charge and discharge times of the energy storage battery and a charge and discharge number threshold, determines the ratio of the first difference to a predetermined number difference threshold as first characteristic data, and calculates a second difference between the charge and discharge depth of the energy storage battery and a charge and discharge depth threshold, determines the ratio of the second difference to a predetermined depth difference threshold as second characteristic data, and determines the sum of the first characteristic data and the second characteristic data as the battery life impact characterization value.

[0039] In implementation, the predetermined depth difference threshold is obtained in advance and is determined based on the average value of the difference between the charge and discharge depths and the depth threshold obtained in several historical cycles, and is set to be between 1.05 and 1.15 times the average value of the difference.

[0040] Similarly, the predetermined number difference threshold is obtained in advance and is determined based on the average value of the difference between the number of charge and discharge times obtained in several historical periods and the charge and discharge number threshold, and is set to between 1.1 and 1.2 times the average value of the difference.

[0041] Specifically, the change in the number of charge and discharge times of the energy storage battery reflects the difference in battery life characteristics. The charge and discharge number threshold and the difference threshold are reference values ​​used to measure whether the degree of such change is significant. In implementation, the charge and discharge number threshold is set as the average value of the charge and discharge number in several historical cycles, and the predetermined difference threshold is set as the average value of the difference in several historical cycles. By calculating the ratio, the change in the charge and discharge number can be standardized, which is convenient for comparison and comprehensive analysis with other characteristics.

[0042] Specifically, the difference between the charge and discharge depth of the energy storage battery and the charge and discharge depth threshold, and the ratio of the predetermined difference threshold, are similar. The charge and discharge depth of the energy storage battery will also affect the battery life. This ratio can reflect the degree of impact on the battery life. In implementation, the charge and discharge threshold is set to the average value of the charge and discharge depth in several historical cycles, and the predetermined difference threshold is the average value of the difference in several historical cycles. The sum of these two ratios is used as the characteristic data, comprehensively considering the changes of two important charge and discharge parameters, namely the change of charge and discharge number and the change of charge and discharge depth under different temperature influence cycles.

[0043] Specifically, the first characteristic data and the second characteristic data are added together to obtain a battery life impact value. This value integrates the impact of multiple charge and discharge parameters, including changes in charge and discharge frequency and charge and discharge depth, on battery life under different temperature influence cycles. It can more comprehensively reflect the battery life impact characteristics of the energy storage battery under a specific temperature influence cycle.

[0044] Specifically, by analyzing multiple charge and discharge parameters, we can more accurately assess the impact of temperature on the lifespan of energy storage batteries. Different charge and discharge parameters reflect the changes in battery characteristics from different perspectives. Comprehensively considering these parameters can reduce the limitations of single-parameter evaluation and provide a more comprehensive and accurate temperature impact assessment.

[0045] See also Figure 4 As shown, it is a logic decision diagram for dividing the micro power supply impact cycle based on the battery life impact characterization value according to an embodiment of the present invention. The controller of the present invention is used to divide the micro power supply impact cycle based on the battery life impact characterization value corresponding to different temperature impact cycles. The controller determines that the micro power source impact period is a significant impact period according to a condition that the battery life impact characterization value is greater than or equal to a preset impact characterization value; According to the condition that the battery life impact characterization value is less than the preset impact characterization value, the micro power source impact period is determined to be a weak impact period.

[0046] Specifically, the preset impact characterization value serves as a key judgment criterion, playing the role of dividing the significant impact period and the weak impact period. In implementation, the preset impact tendency characterization value is selected within the range of [2.15,2.25].

[0047] Specifically, when the battery life impact characteristic value is greater than or equal to the preset impact characteristic value, it is determined to be a significant impact period. This means that during this period, the temperature has a significant impact on the life of the energy storage battery, which may cause a significant change in battery performance.

[0048] Specifically, if the battery life impact indicator value is less than the preset impact indicator value, it is determined to be a weak impact period. During this period, the temperature has a relatively small impact on the energy storage battery life, and the battery performance changes are relatively subtle. During this period, the battery can operate in a relatively stable state, and performance indicators such as charge and discharge efficiency and lifespan are relatively stable.

[0049] Specifically, the power monitoring unit includes a hardware counting module for monitoring the number of charge and discharge times of the energy storage battery, and a coulomb counter module for monitoring the charge and discharge depth of the energy storage battery; the analyzer also includes a storage unit for storing historical data monitored by the monitor.

[0050] Specifically, the controller is used to monitor the operating status of the micro power source based on the division result of the micro power source impact period. The controller determines whether the energy storage battery has an abnormality based on the difference between the battery life impact characterization value of the energy storage battery area in the actual historical period and the predetermined battery life impact characterization value according to the weak impact period condition; If it is determined that the cycle condition is significantly affected, determining whether to enable the backup power supply based on the difference between the actual operating time of the energy storage battery and the predetermined operating time threshold; If the difference between the actual operating time of the energy storage battery and the predetermined operating time threshold is greater than the predetermined operating time difference threshold condition, it is determined to enable the backup power supply.

[0051] Specifically, the predetermined operating time threshold is determined based on the average actual operating time of the energy storage battery obtained over several historical periods and is set between 0.90 and 0.95 times the average actual operating time. The predetermined operating time difference threshold is determined based on the average difference between the actual operating time of the energy storage battery obtained over several historical periods and the predetermined operating time threshold and is set between 1.1 and 1.15 times the average of the difference.

[0052] In practice, temperature has a significant impact on the life of energy storage batteries during periods of significant impact. By measuring the temperature variance of the energy storage battery area within a predetermined period, we can more comprehensively assess the impact of temperature on the entire micro power system.

[0053] During implementation, the cost and benefit of using a temperature compensation device should be considered during the significant impact period. The power consumption of the temperature compensation device is an important consideration. If the power consumption caused by the temperature compensation device is too high, it may lead to reduced efficiency of the entire system.

[0054] Specifically, the energy storage battery life impact characterization values ​​corresponding to different temperature impact cycles can distinguish the micro-power source impact cycles, including significant impact and weak impact cycles, to improve energy utilization efficiency. Moreover, by determining whether the temperature compensation device of the energy storage battery is enabled, the energy utilization efficiency is further improved.

[0055] Specifically, the controller is used to determine the difference between the battery life impact characterization value of the energy storage battery area within a predetermined period and a predetermined battery life characterization value as the life impact characterization value. If the life impact characterization value is greater than the preset life impact characterization value difference threshold condition, it is determined that there is an abnormality in the energy storage battery.

[0056] In implementation, the preset life impact characterization difference threshold is obtained in advance, and the life impact characterization difference threshold is determined based on the average value of the life impact characterization values ​​obtained in several historical periods, and is set between 1.05 times and 1.15 times the average value.

[0057] Specifically, the controller is used to determine whether to enable the temperature compensation device based on the variance of the temperature of the energy storage battery area within a predetermined period according to the presence of an abnormal condition in the energy storage battery.

[0058] Specifically, the controller calculates the variance of the temperature of the energy storage battery area within a predetermined period, and determines to enable the temperature compensation device if the variance is greater than or equal to a variance threshold condition.

[0059] In implementation, the variance threshold is obtained in advance and is determined based on the average variance of temperatures obtained in several historical periods, and is set to be between 1.15 times and 1.25 times the average variance.

[0060] Specifically, by identifying the temperature influence cycle, the law of how the energy storage battery is affected by temperature in different time periods can be accurately obtained. The variance of the temperature in the historical period reflects the temperature fluctuation. The impact of the fluctuation difference on the battery life is also differentiated. By calculating the variance of the temperature of the energy storage battery area in each historical period, the temperature fluctuation can be accurately obtained. When the fluctuation is large, the impact on the battery life can be reduced by turning on the temperature compensation device. When the fluctuation is small, the battery operates normally. Not turning on the temperature compensation device can save energy and improve the comprehensive utilization of resources. Therefore, judging whether to enable the temperature compensation device based on the temperature variance can improve the comprehensive utilization efficiency of resources. Moreover, the changes in the charging and discharging parameters can accurately analyze the energy storage battery life impact characterization value in different temperature influence cycles, reduce the number of charge and discharge times and the misjudgment of the battery life due to the charge and discharge depth exceeding the threshold, and improve the control efficiency of the micro power supply.

[0061] Specifically, the present invention provides an integrated micro power supply for a communication base station, which also includes an integrated chassis, and an input module, an output module, a rectifier module, a lightning arrester, a micro power supply component, a monitor, an analyzer and a controller arranged in the integrated chassis.

[0062] During implementation, the high degree of centralization of the integrated chassis reduces the equipment's footprint and space occupancy, making it suitable for communication base stations with limited space, especially small base stations and outdoor base stations. Moreover, the integrated design is easy to install, shortening installation time and engineering complexity, and improving construction efficiency. At the same time, the temperature compensation device can be used in various outdoor environments, reducing the occurrence of low micro-power control efficiency caused by ambient temperature changes.

[0063] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
