Then query the preset charging parameter database according to the rated capacity and battery category characteristic data to obtain the charging current corresponding to the constant current charging stage. Among them, the preset charging parameter database is obtained by querying the preset high-power UPS battery life optimization management platform. For example, for a 100Ah lead-acid battery in the constant current charging stage, the charging device will output a stable 0.1C current, that is, 0.1x100 = 10A, to gradually increase the battery voltage; at the same time, obtain the real-time charging monitoring voltage of the single battery. When it is greater than or equal to the preset equalizing charge voltage, it means that the constant current charging stage ends and the constant voltage charging stage begins. Among them, the preset equalizing charge voltage is obtained by querying the preset high-power UPS battery life optimization management platform. Further query the preset charging parameter database according to the battery category characteristic data to obtain the charging demand voltage corresponding to the constant voltage charging stage, and control the high-power UPS battery to perform constant voltage charging according to the charging demand voltage to reduce the impact of improper charging on the battery life.

[0115] According to the embodiment of the present invention, it further includes:

[0116] Obtain the real-time ambient temperature at the location where the high-power UPS battery is located;

[0117] Compare the real-time ambient temperature with the preset standard ambient temperature to obtain an ambient temperature difference value, and query the preset charging voltage compensation adjustment database according to the ambient temperature difference value to obtain a temperature compensation voltage;

[0118] Sum the temperature compensation voltage and the charging demand voltage to obtain a charging correction voltage;

[0119] Control the high-power UPS battery to perform constant-voltage charging according to the charging correction voltage.

[0120] It should be noted that the ambient temperature has a significant impact on the charging performance of the battery, especially for lead-acid batteries. Therefore, in order to more accurately determine the charging demand voltage in the constant-voltage charging stage, first obtain the real-time ambient temperature at the location of the high-power UPS battery, compare it with the preset standard ambient temperature to obtain an ambient temperature difference value. The ambient temperature difference value refers to the difference between the real-time ambient temperature and the preset standard ambient temperature. For example, if the real-time ambient temperature is 26°C and the preset standard ambient temperature is 25°C, then 26 - 25 = 1°C is the ambient temperature difference value. If the real-time ambient temperature is 24°C, then 24 - 25 = -1°C is the ambient temperature difference value. Query the preset charging voltage compensation adjustment database according to the ambient temperature difference value to obtain a temperature compensation voltage. Among them, the temperature compensation voltage can be positive or negative, and the preset charging voltage compensation adjustment database is obtained by querying the preset high-power UPS battery life optimization management platform. Then sum the temperature compensation voltage and the charging demand voltage to obtain a charging correction voltage;

[0121] The calculation formula for the charging correction voltage is:

[0122] ;

[0123] Among them, is the charging correction voltage, 、 are the temperature compensation voltage and the charging demand voltage respectively.

[0124] It is worth mentioning that according to the embodiment of the present invention, it further includes:

[0128] If it is less than or equal to the first temperature threshold, it is determined that the discharge battery temperature is normal;

[0129] If it is greater than the first temperature threshold and less than or equal to the second temperature threshold, it is determined that the temperature of the discharging battery is abnormal, and the refrigeration and cooling response is activated;

[0130] If it is greater than the second temperature threshold, it is determined that the temperature of the discharging battery is abnormal, and the load adjustment response is activated.

[0131] It should be noted that when the high-power UPS battery executes the discharging instruction, the battery temperature will increase accordingly, and the battery life will also be greatly affected. Therefore, it is necessary to obtain the real-time battery temperature of the sub-battery during the discharging stage and compare it with the preset temperature threshold. The temperature threshold includes the first temperature threshold and the second temperature threshold. In this embodiment, the first temperature threshold is set to 40 °C, and the second temperature threshold is set to 45 °C. If the obtained real-time temperature is 35 °C, it is determined that the temperature of the discharging battery is normal; if the obtained real-time temperature is 41 °C, it is determined that the temperature of the discharging battery is abnormal, and the refrigeration and cooling response is activated to reduce the battery temperature; if the obtained real-time temperature is 46 °C, indicating that the cooling effect is insufficient, it is determined that the temperature of the discharging battery is abnormal, and the load adjustment response is activated, such as allocating the load to the backup battery for power supply.

[0132] It is worth mentioning that according to the embodiment of the present invention, the real-time capacity data and the corresponding conversion rate of the sub-battery of the high-power UPS battery are obtained according to the discharging instruction information, and the obtained real-time capacity data and the corresponding conversion rate are processed in combination with the predicted energy demand data to obtain the discharging distribution strategy of the high-power UPS battery. After that, it further includes:

[0133] Obtain the discharging effectiveness parameter data of the high-power UPS battery, including the real-time remaining capacity deviation value, the voltage range between sub-batteries, and the voltage standard deviation of sub-batteries;

[0134] Input the real-time remaining capacity deviation value, the voltage range between sub-batteries, and the voltage standard deviation of sub-batteries into a preset discharging effectiveness evaluation model for processing to obtain a discharging effectiveness evaluation index.

[0135] It should be noted that after the high-power UPS battery executes the discharging action, it is necessary to evaluate the discharging effectiveness of each sub-battery. First, obtain the discharging effectiveness parameter data including the real-time remaining capacity deviation value, the voltage range between sub-batteries, and the voltage standard deviation of sub-batteries. Among them, the real-time remaining capacity deviation value refers to the absolute value of the difference between the real-time remaining capacity of the sub-battery and the preset expected remaining capacity, and the preset expected remaining capacity is obtained by querying through a preset high-power UPS battery life optimization management platform. The voltage range between sub-batteries refers to the difference between the highest voltage and the lowest voltage of the sub-batteries. Input the real-time remaining capacity deviation value, the voltage range between sub-batteries, and the voltage standard deviation of sub-batteries into a preset discharging effectiveness evaluation model for processing to obtain a discharging effectiveness evaluation index;

[0136] In the discharge effectiveness evaluation model, the calculation formula for the discharge effectiveness evaluation index is as follows:

[0137] ;

[0138] Wherein, is the discharge effectiveness evaluation index, 、 、 are the real-time remaining capacity deviation value, the voltage range between sub-batteries, and the voltage standard deviation of sub-batteries respectively, is a preset characteristic coefficient (the characteristic coefficient is obtained by querying through a preset high-power UPS battery life optimization management platform).

[0139] It should be noted that according to the embodiment of the present invention, after inputting the real-time remaining capacity deviation value, the voltage range between batteries, and the voltage standard deviation between batteries into the preset discharge effectiveness evaluation model for processing to obtain the discharge effectiveness evaluation index, it further includes:

[0140] Comparing the discharge effectiveness evaluation index with a preset discharge reference index to obtain a discharge effectiveness deviation rate;

[0141] Comparing the discharge effectiveness deviation rate with a preset discharge effectiveness deviation rate threshold;

[0142] If it is less than or equal to the preset discharge effectiveness deviation rate threshold, it is determined that the discharge distribution strategy is normal;

[0143] If it is greater than the preset discharge effectiveness deviation rate threshold, it is determined that the discharge distribution strategy is abnormal.

[0144] It should be noted that by comparing the obtained discharge effectiveness evaluation index with a preset discharge reference index to obtain a discharge effectiveness deviation rate, the discharge effectiveness deviation rate is the ratio of the absolute value of the difference between the discharge effectiveness evaluation index and the preset discharge reference index to the discharge reference index. By comparing the obtained discharge effectiveness deviation rate with a preset discharge effectiveness deviation rate threshold, in this embodiment, the discharge effectiveness deviation rate threshold is set to (0, 0.25] and (0.25, 1], corresponding to a normal discharge distribution strategy and an abnormal discharge distribution strategy respectively. For example, if the obtained discharge effectiveness deviation rate is 0.2, it is determined that the discharge distribution strategy is normal; if the obtained discharge effectiveness deviation rate is 0.3, it is determined that the discharge distribution strategy is abnormal.

[0145] It should be noted that according to the embodiment of the present invention, it further includes:

[0146] Obtaining the real-time voltage corresponding to the sub-battery of the high-power UPS battery and extracting the real-time highest voltage value according to the real-time voltage;

[0148] Compare the voltage difference with a preset voltage equalization threshold value;

[0149] If it is less than or equal to the preset voltage equalization threshold value, it is determined that the battery voltages are balanced;

[0150] If it is greater than the preset voltage equalization threshold value, it is determined that the battery voltages are unbalanced, and the corresponding sub-battery is charged.

[0151] It should be noted that during long-term use, the batteries in the battery pack may have uneven charging. For a series-connected UPS battery pack, it is very important to perform equalization charging regularly. First, obtain the real-time voltage corresponding to the sub-battery of the high-power UPS battery, extract the real-time highest voltage value according to the real-time voltage, then compare the real-time voltages with the real-time highest voltage value respectively to obtain the corresponding voltage differences. The voltage difference refers to the difference between the real-time highest voltage value and the real-time voltage. Finally, compare the voltage difference with the preset voltage equalization threshold value. In this embodiment, the voltage equalization threshold value is set to 0.2V. For example, if the obtained voltage difference is 0.1V, which is less than the preset voltage equalization threshold value, it is determined that the battery voltages are balanced. If the obtained voltage difference is 0.3V, which is greater than the preset voltage equalization threshold value, it is determined that the battery voltages are unbalanced, and the corresponding sub-battery is charged to keep the voltages of all sub-batteries balanced.

[0152] It is worth mentioning that according to the embodiment of the present invention, it further includes:

[0158] If it is greater than or equal to the preset monitoring number threshold value, control the high-power UPS battery to enter battery sleep.

[0159] It should be noted that in the case of stable mains power supply for a long time, the battery sleep program is started to place the battery in a low-power state, reducing self-discharge and unnecessary charge-discharge cycles, which can extend the service life of the high-power UPS battery. First, the stability of the mains power supply is evaluated by obtaining the average voltage fluctuation, average frequency fluctuation, average harmonic distortion, and number of power outages within a preset time period. Among them, the average voltage fluctuation refers to the average value of the differences between multiple collected real-time voltages and the preset reference voltage, the average frequency fluctuation refers to the average value of the differences between multiple collected real-time frequencies and the preset reference frequency, and the average harmonic distortion can be obtained by those skilled in the art through calculating the effective values of multiple collected harmonic voltages and the effective value of the preset fundamental voltage. In this embodiment, the preset time period is set to 1 day. Based on the obtained average voltage fluctuation, average frequency fluctuation, average harmonic distortion, and number of power outages, processing is performed to obtain the power supply stability evaluation index within the preset time period;

[0160] The calculation formula for the power supply stability evaluation index is as follows:

[0161] ;

[0162] Wherein, is the power supply stability evaluation index, , , , are respectively the average voltage fluctuation, average frequency fluctuation, average harmonic distortion, and number of power outages, , are preset characteristic coefficients (the characteristic coefficients are obtained by querying through a preset high-power UPS battery life optimization management platform);

[0163] The obtained power supply stability evaluation index is compared with the preset power supply stability evaluation threshold. In this embodiment, the power supply stability evaluation threshold is set to (0, 0.8], (0.8, 1]. For example, if the obtained power supply stability evaluation index is 0.7, which is less than the preset power supply stability evaluation threshold, the number of times is not counted. If the obtained power supply stability evaluation index is 0.85, which is greater than the preset power supply stability evaluation threshold, it is recorded as 1 time. Further, the number of times within the preset time period when the index is continuously greater than the preset power supply stability evaluation threshold is obtained, and then the number of times is compared with the preset monitoring number threshold. In this embodiment, the preset monitoring number threshold is set to 7 times. If the obtained number of times is 5 times, which is less than 7 times, the high-power UPS battery does not enter the sleep state. If the obtained number of times is 8 times, which is greater than 7 times, it indicates that the mains power supply is stable, and then the high-power UPS battery is controlled to enter the battery sleep state, reducing self-discharge and the number of unnecessary charge-discharge cycles, achieving the purpose of extending the service life.

[0217] It should be noted that in order to optimize the life of the high-power UPS battery, while optimizing the discharge distribution, it is necessary to analyze and optimize the charging method to further improve the service life of the high-power UPS battery. The charging process is optimized into two stages: constant current charging and constant voltage charging. In the constant current charging stage, first obtain the rated capacity of the high-power UPS battery and the battery category characteristic data. The battery category characteristic data refers to the lead-acid battery category characteristic data or the lithium battery category characteristic data. Then query the preset charging parameter database according to the rated capacity and the battery category characteristic data to obtain the charging current corresponding to the constant current charging stage. Among them, the preset charging parameter database is obtained by querying the preset high-power UPS battery life optimization management platform. For example, for a lead-acid battery with a capacity of 100Ah in the constant current charging stage, the charging device will output a stable 0.1C current, that is, 0.1×100 = 10A, to gradually increase the battery voltage. At the same time, obtain the real-time charging monitoring voltage of the single battery. When it is greater than or equal to the preset equalizing charge voltage, it indicates that the constant current charging stage ends and the constant voltage charging stage begins. Among them, the preset equalizing charge voltage is obtained by querying the preset high-power UPS battery life optimization management platform. Further query the preset charging parameter database according to the battery category characteristic data to obtain the charging required voltage corresponding to the constant voltage charging stage, and control the high-power UPS battery to perform constant voltage charging according to the charging required voltage to reduce the impact of improper charging on the battery life.

[0221] Perform a summation calculation on the temperature compensation voltage and the charging required voltage to obtain the charging correction voltage;

[0222] Control the high-power UPS battery to perform constant voltage charging according to the charging correction voltage.

[0223] It should be noted that the ambient temperature has a significant impact on the charging performance of the battery, especially for lead-acid batteries. Therefore, in order to more accurately determine the charging required voltage in the constant voltage charging stage, first obtain the real-time ambient temperature at the location of the high-power UPS battery, compare it with the preset standard ambient temperature, and obtain the ambient temperature difference value. The ambient temperature difference value refers to the difference between the real-time ambient temperature and the preset standard ambient temperature. For example, if the real-time ambient temperature is 26°C and the preset standard ambient temperature is 25°C, then 26 - 25 = 1°C is the ambient temperature difference value. If the real-time ambient temperature is 24°C, then 24 - 25 = -1°C is the ambient temperature difference value. Query the preset charging voltage compensation adjustment database according to the ambient temperature difference value to obtain the temperature compensation voltage. Among them, the temperature compensation voltage can be positive or negative. The preset charging voltage compensation adjustment database is obtained by querying the preset high-power UPS battery life optimization management platform, and then sum the temperature compensation voltage and the charging required voltage to obtain the charging corrected voltage;

[0227] It is worth mentioning that according to the embodiment of the present invention, it further includes:

[0228] Obtain the real-time battery temperature of the sub-battery in the discharge stage of the high-power UPS battery;

[0229] Compare the real-time battery temperature with a preset temperature threshold;

[0233] If it is greater than the second temperature threshold, it is determined that the discharge battery temperature is abnormal and activate the load adjustment response.

[0234] It should be noted that when the high-power UPS battery executes the discharge command, the battery temperature will increase accordingly, and the battery life will also be greatly affected. Therefore, it is necessary to obtain the real-time battery temperature of the sub-battery during the discharge stage and compare it with the preset temperature threshold. The temperature threshold includes the first temperature threshold and the second temperature threshold. In this embodiment, the first temperature threshold is set to 40 °C, and the second temperature threshold is set to 45 °C. If the obtained real-time temperature is 35 °C, it is determined that the discharge battery temperature is normal; if the obtained real-time temperature is 41 °C, it is determined that the discharge battery temperature is abnormal, and the refrigeration and cooling response is activated to reduce the battery temperature; if the obtained real-time temperature is 46 °C, indicating that the cooling effect is insufficient, it is determined that the discharge battery temperature is abnormal, and the load adjustment response is activated, such as allocating the load to the backup battery for power supply.

[0235] It is worth mentioning that according to the embodiment of the present invention, the real-time capacity data and the corresponding conversion rate of the sub-battery of the high-power UPS battery are obtained according to the discharge instruction information, and the discharge distribution strategy of the high-power UPS battery is obtained by processing the real-time capacity data and the corresponding conversion rate in combination with the energy demand prediction data. After that, it further includes:

[0236] Obtain the discharge effectiveness parameter data of the high-power UPS battery, including the real-time remaining capacity deviation value, the voltage range between sub-batteries, and the standard deviation of the sub-battery voltage;

[0237] Input the real-time remaining capacity deviation value, the voltage range between sub-batteries, and the standard deviation of the sub-battery voltage into a preset discharge effectiveness evaluation model for processing to obtain a discharge effectiveness evaluation index.

[0238] It should be noted that after the high-power UPS battery executes the discharge action, it is necessary to evaluate the discharge effectiveness of each sub-battery. First, obtain the discharge effectiveness parameter data including the real-time remaining capacity deviation value, the voltage range between sub-batteries, and the standard deviation of the sub-battery voltage. Among them, the real-time remaining capacity deviation value refers to the absolute value of the difference between the real-time remaining capacity of the sub-battery and the preset expected remaining capacity. The preset expected remaining capacity is obtained by querying the preset high-power UPS battery life optimization management platform. The voltage range between sub-batteries refers to the difference between the highest voltage and the lowest voltage of the sub-battery. Input the real-time remaining capacity deviation value, the voltage range between sub-batteries, and the standard deviation of the sub-battery voltage into a preset discharge effectiveness evaluation model for processing to obtain a discharge effectiveness evaluation index;

[0239] The calculation formula of the discharge effectiveness evaluation index in the discharge effectiveness evaluation model is:

[0240] ;

[0241] Among them, is the discharge effectiveness evaluation index, 、 、 They are the real-time remaining capacity deviation value, the voltage range between sub-batteries, and the standard deviation of sub-battery voltages, which are preset characteristic coefficients (the characteristic coefficients are obtained by querying through a preset high-power UPS battery life optimization management platform).

[0242] It is worth mentioning that according to the embodiments of the present invention, after inputting the real-time remaining capacity deviation value, the voltage range between batteries, and the standard deviation of battery voltages into a preset discharge effectiveness evaluation model for processing to obtain a discharge effectiveness evaluation index, the following steps are further included:

[0243] Comparing the discharge effectiveness evaluation index with a preset discharge reference index to obtain a discharge effectiveness deviation rate;

[0244] Comparing the discharge effectiveness deviation rate with a preset discharge effectiveness deviation rate threshold;

[0245] If it is less than or equal to the preset discharge effectiveness deviation rate threshold, it is determined that the discharge distribution strategy is normal;

[0246] If it is greater than the preset discharge effectiveness deviation rate threshold, it is determined that the discharge distribution strategy is abnormal.

[0247] It should be noted that by comparing the obtained discharge effectiveness evaluation index with a preset discharge reference index to obtain a discharge effectiveness deviation rate, the discharge effectiveness deviation rate is the ratio of the absolute value of the difference between the discharge effectiveness evaluation index and the preset discharge reference index to the discharge reference index. Comparing the obtained discharge effectiveness deviation rate with a preset discharge effectiveness deviation rate threshold. In this embodiment, the discharge effectiveness deviation rate threshold is set to (0, 0.25] and (0.25, 1], corresponding to a normal discharge distribution strategy and an abnormal discharge distribution strategy respectively. For example, if the obtained discharge effectiveness deviation rate is 0.2, it is determined that the discharge distribution strategy is normal; if the obtained discharge effectiveness deviation rate is 0.3, it is determined that the discharge distribution strategy is abnormal.

[0248] It is worth mentioning that according to the embodiments of the present invention, the following steps are further included:

[0249] Obtaining the real-time voltage corresponding to the sub-battery of the high-power UPS battery and extracting the real-time highest voltage value according to the real-time voltage;

[0250] Comparing the real-time voltage with the real-time highest voltage value respectively to obtain the corresponding voltage difference;

[0251] Comparing the voltage difference with a preset voltage equalization threshold;

[0252] If it is less than or equal to the preset voltage equalization threshold, it is determined that the battery voltages are balanced;

[0253] If it is greater than the preset voltage equalization threshold, it is determined that the battery voltage is unbalanced, and the corresponding sub-battery is charged.

[0254] It should be noted that during long-term use, the batteries in the battery pack may experience uneven charging. For a series-connected UPS battery pack, it is very important to perform equalization charging regularly. First, obtain the real-time voltage corresponding to the sub-battery of the high-power UPS battery, extract the real-time highest voltage value according to the real-time voltage, and then compare the real-time voltage with the real-time highest voltage value respectively to obtain the corresponding voltage difference. The voltage difference refers to the difference between the real-time highest voltage value and the real-time voltage. Finally, compare the voltage difference with the preset voltage equalization threshold. In this embodiment, the voltage equalization threshold is set to 0.2V. For example, if the obtained voltage difference is 0.1V, which is less than the preset voltage equalization threshold, it is determined that the battery voltage is balanced. If the obtained voltage difference is 0.3V, which is greater than the preset voltage equalization threshold, it is determined that the battery voltage is unbalanced, and the corresponding sub-battery is charged to keep the voltages of all sub-batteries balanced.

[0255] It is worth mentioning that according to the embodiment of the present invention, it further includes:

[0256] Obtain the voltage fluctuation mean value, frequency fluctuation mean value, harmonic distortion mean value, and power outage frequency value of the commercial power within a preset time period;

[0257] Process according to the voltage fluctuation mean value, frequency fluctuation mean value, harmonic distortion mean value, and power outage frequency value to obtain the power supply stability evaluation index of the commercial power within a preset time period;

[0258] Compare the power supply stability evaluation index with a preset power supply stability evaluation threshold to obtain the number value of the preset time period continuously greater than the preset power supply stability evaluation threshold;

[0259] Compare the number value with a preset monitoring number threshold;

[0260] If it is less than the preset monitoring number threshold, control the high-power UPS battery not to enter the battery sleep state;

[0261] If it is greater than or equal to the preset monitoring number threshold, control the high-power UPS battery to enter the battery sleep state.

[0262] It should be noted that in the case of stable mains power supply for a long time, the battery sleep program is started to place the battery in a low-power state, reducing self-discharge and unnecessary charge-discharge cycles, which can extend the service life of the high-power UPS battery. First, the stability of the mains power supply is evaluated by obtaining the average voltage fluctuation, average frequency fluctuation, average harmonic distortion, and number of power outages within a preset time period. Among them, the average voltage fluctuation refers to the average value of the differences between multiple collected real-time voltages and the preset reference voltage. The average frequency fluctuation refers to the average value of the differences between multiple collected real-time frequencies and the preset reference frequency. The average harmonic distortion can be obtained by those skilled in the art through calculating the effective values of multiple collected harmonic voltages and the effective value of the preset fundamental voltage. In this embodiment, the preset time period is set to 1 day. Based on the obtained average voltage fluctuation, average frequency fluctuation, average harmonic distortion, and number of power outages, processing is performed to obtain the power supply stability evaluation index within the preset time period;

[0263] The formula for calculating the power supply stability evaluation index is:

[0264] ;

[0265] Wherein, is the power supply stability evaluation index, , , , are respectively the average voltage fluctuation, average frequency fluctuation, average harmonic distortion, and number of power outages, , are preset characteristic coefficients (the characteristic coefficients are obtained by querying through a preset high-power UPS battery life optimization management platform);

[0266] The obtained power supply stability evaluation index is compared with the preset power supply stability evaluation threshold. In this embodiment, the power supply stability evaluation threshold is set to (0, 0.8], (0.8, 1]. For example, if the obtained power supply stability evaluation index is 0.7, which is less than the preset power supply stability evaluation threshold, the number of times is not counted. If the obtained power supply stability evaluation index is 0.85, which is greater than the preset power supply stability evaluation threshold, it is recorded as 1 time. Further, the number of times within the preset time period when the index is continuously greater than the preset power supply stability evaluation threshold is obtained, and then the number of times is compared with the preset monitoring number threshold. In this embodiment, the preset monitoring number threshold is set to 7 times. If the obtained number of times is 5 times, which is less than 7 times, the high-power UPS battery does not enter the sleep state. If the obtained number of times is 8 times, which is greater than 7 times, it indicates that the mains power supply stability is good, then the high-power UPS battery is controlled to enter the battery sleep state, reducing self-discharge and the number of unnecessary charge-discharge cycles, achieving the purpose of extending the service life.
