The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Example 1 Taking the 48V backup battery system commonly used in communication base stations as an example, there are mainly two types: lead-acid batteries and lithium iron phosphate batteries. Both are connected in series and parallel to form 48V, 100~200Ah battery modules to power the equipment in the communication base station. Among them, the voltage of a single lead-acid battery is 1.5~2.4V (nominal voltage is 2V). After 24 batteries are connected in series to form a module, the voltage range is 36~57.6V (nominal voltage is 48V). 95% of its capacity is concentrated in the 2.0~2.3V range of the individual cells, corresponding to a module voltage of 48~55.2V. The voltage of a single lithium iron phosphate battery is 2.5~3.65V (nominal voltage is 3.2V). After 15 batteries are connected in series to form a module, the voltage range is 37.5~54.75V (nominal voltage is 48V). 95% of its capacity is concentrated in the 3.15~3.35V range of the individual cells, corresponding to a module voltage of 47.25~50.25V.

[0021] Both types of batteries mentioned above have a main voltage range compatible with the operating voltage range of 43.2~57.6V for base station equipment, and can be used directly without additional auxiliary equipment. In contrast, sodium-ion batteries have a wider single-cell voltage range, specifically 1.5~3.8V, with a nominal voltage of 3V. When 16 cells are connected in series to form a module, the voltage range is 24~60.8V (nominal voltage 48V), and the charge is evenly distributed across the entire voltage range. Therefore, when supplying power to equipment operating at 43.2~57.6V, the energy below 43.2V and above 57.6V in the module is wasted because it cannot match the voltage requirements of the equipment, accounting for approximately 45% of the total energy, resulting in significant energy loss. Table 1 below shows a comparison of energy loss between different types of batteries.

[0022] Table 1

[0023] For this, please see Figure 1 This application provides a voltage intelligent control system 100, including: an energy storage module 110, a control module 120, and a charging / discharging module 130. The energy storage module 110 is electrically connected to the control module 120 and the charging / discharging module 130, respectively. The charging / discharging module 130 is also electrically connected to the control module 120, a voltage conversion module 300, and a load 400, respectively. The control module 120 is also electrically connected to the voltage conversion module 300. The voltage conversion module 300 is electrically connected to the mains power system 200 and the load 400, respectively. The voltage conversion module 300 is used to obtain the mains voltage from the mains power system 200, convert the mains voltage into a target voltage, and output it to the load 400, so as to realize the supply of power from the mains power system 200 to the load 400. The control module 120 is used to obtain the current output voltage of the voltage conversion module 300. If the current output voltage of the voltage conversion module 300 is less than a preset discharge voltage value, the control module 120 obtains the current output voltage of the energy storage module 110 and sends a first voltage adjustment signal to the charge and discharge module 130 based on the current output voltage of the energy storage module 110 and the preset discharge voltage value, wherein the preset discharge voltage value is less than the target voltage. The charging and discharging module 130 is used to obtain the current output voltage of the energy storage module 110 when it receives the first voltage adjustment signal, and adjust the current output voltage of the energy storage module 110 to the preset discharge voltage value before outputting it to the load 400, so as to realize that the energy storage module 110 supplies power to the load 400.

[0024] In this embodiment, the voltage conversion module 300 is used to obtain the mains voltage from the mains system 200 and convert the mains voltage into the target voltage required by the load 400 to supply power to the load 400. During the power supply from the mains system 200 to the load 400, the control module 120 monitors the current output voltage of the voltage conversion module 300 in real time. When it is detected that the current output voltage of the voltage conversion module 300 is less than the preset discharge voltage value, it is determined that the power supply of the mains system 200 is abnormal. Then, the current output voltage of the energy storage module 110 is collected, and a first voltage adjustment signal is sent to the charge and discharge module 130 according to the current output voltage of the energy storage module 110 and the preset discharge voltage value. After receiving the first voltage adjustment signal, the charging and discharging module 130 adjusts the current output voltage of the energy storage module 110 to a preset discharge voltage value and then supplies power to the load 400, thereby switching the power supply from the mains power system 200 to the energy storage module 110. It should be noted that the preset discharge voltage value is less than the target voltage. For example, in this embodiment, the preset discharge voltage value = target voltage value - 3V, in order to avoid conflict between the power supply of the energy storage module 110 and the power supply of the mains power system 200.

[0025] It is understood that in this embodiment, the energy storage module 110 includes a sodium-ion battery module composed of multiple sodium-ion individual cells. Through real-time monitoring by the control module 120 and voltage regulation by the charge / discharge module 130, the switching from power supply from the mains system 200 to the energy storage module 110 is achieved, while also ensuring the compatibility of the output voltage of the energy storage module 110 with the load 400. Through voltage regulation, the output voltage of the energy storage module 110 is always adapted to the operating voltage of the load 400, realizing the full energy range utilization of the sodium-ion battery and avoiding energy waste. The energy storage module 110 is separate from the charge / discharge module 130, and the output power of the energy storage module 110 can be configured according to actual needs.

[0026] In one implementation, please refer to Figure 2The charging and discharging module 130 includes: a discharging unit 131, which is electrically connected to the control module 120, the energy storage module 110, and the load 400 respectively; the control module 120 is further configured to send a discharge control signal to the discharging unit 131 if the current output voltage of the voltage conversion module 300 is less than the preset discharge voltage value; the discharging unit 131 is configured to turn on when it receives the discharge control signal, so that the energy storage module 110 is electrically connected to the load 400.

[0027] In this embodiment, when the current output voltage of the voltage conversion module 300 is less than the preset discharge voltage value, it indicates that the mains power system 200 is abnormal or interrupted. At this time, the control module 120 determines that it needs to switch to the energy storage module 110 for power supply, and then sends a discharge control signal to the discharge unit 131 in the charge / discharge module 130. After receiving the discharge control signal, the discharge unit 131 is turned on, so that the energy storage module 110 is electrically connected to the load 400. At this time, the energy storage module 110 can supply power to the load 400 through the discharge unit 131. Specifically, the discharge unit 131 includes, as follows: Figure 3 The bidirectional topology circuit shown is normally in hot standby mode, maintaining no-load output but not conducting.

[0028] Figure 3 In the circuit shown: BAT_IN+ and BAT_IN- represent the positive and negative terminals of the input voltage of the energy storage module 110, respectively, and LOAD_OUT+ and LOAD_OUT- represent the positive and negative terminals of the output voltage to the load 400, respectively. Figure 3 The circuit shown works as follows: MOS switch Q1 is normally open during normal operation. Q2 and Q3 are a pair of mutually exclusive PWM transistors, as are Q4 and Q5. Assuming the PWM duty cycle of Q2 is D1 and the duty cycle of Q4 is D2, the output voltage to the load 400V = the input voltage of energy storage module 110 × (D1 / (1-D2)). Let D = (D1 / (1-D2)). Then, when D < 1, the discharge unit 131 operates at a step-down voltage; when D > 1, the discharge unit 131 operates at a step-up voltage.

[0029] Furthermore, after the discharge unit 131 is turned on, it automatically switches between boost and buck modes through a switching network composed of built-in MOS and other components based on the first voltage adjustment signal, so as to stabilize and control the voltage output to the load 400 within the voltage range adapted to the load 400.

[0030] In one embodiment, the first voltage adjustment signal includes a first boost signal or a first buck signal; the control module 120 is further configured to send the first boost signal to the discharge unit 131 if the current output voltage of the energy storage module 110 is less than the preset discharge voltage value; and to send the first buck signal to the discharge unit 131 if the current output voltage of the energy storage module 110 is greater than or equal to the preset discharge voltage value.

[0031] In this embodiment, when the current output voltage of the voltage conversion module 300 is less than the preset discharge voltage value, and it is necessary to switch to the energy storage module 110 for power supply, the control module 120 will further determine the current output voltage of the energy storage module 110: if the current output voltage of the energy storage module 110 is less than the preset discharge voltage value, the control module 120 sends a first boost signal to the discharge unit 131; if the current output voltage of the energy storage module 110 is greater than or equal to the preset discharge voltage value, the control module 120 sends a first buck signal to the discharge unit 131, so that the discharge unit 131, based on different signals, operates through corresponding circuits to stably control the voltage output to the load 400 within the appropriate range. This can accurately adapt the voltage of the energy storage module 110 to the needs of the load 400, ensuring stable power supply.

[0032] In one embodiment, the control module 120 is further configured to, if the current output voltage of the voltage conversion module 300 is greater than or equal to the preset discharge voltage value, obtain the current output voltage of the energy storage module 110, and send a second voltage adjustment signal to the charge-discharge module 130 based on the current output voltage of the energy storage module 110 and the current output voltage of the voltage conversion module 300. The charging and discharging module 130 is further configured to, when receiving the second voltage adjustment signal, acquire the current output voltage of the voltage conversion module 300, adjust the current output voltage of the voltage conversion module 300 to a preset charging voltage value, and then output it to the energy storage module 110 to charge the energy storage module 110, wherein the preset charging voltage value is greater than the current output voltage of the energy storage module 110.

[0033] In this embodiment, when the current output voltage of the voltage conversion module 300 is greater than or equal to the preset discharge voltage value, it indicates that the mains power system 200 is supplying power normally. At this time, the control module 120 obtains the current output voltage of the energy storage module 110 and, in conjunction with the current output voltage of the voltage conversion module 300, sends a second voltage adjustment signal to the charge / discharge module 130. After receiving the second voltage adjustment signal, the charge / discharge module 130 adjusts the current output voltage of the voltage conversion module 300 to the preset charging voltage value and then supplies power to the energy storage module 110, so as to achieve normal power supply from the mains power system 200 to the load 400 while charging the energy storage module 110.

[0034] It should be noted that the preset charging voltage value is greater than the current output voltage of the voltage conversion module 300. Specifically, the preset charging voltage value is a dynamic voltage value that changes with the current output voltage of the energy storage module 110. For example, the preset charging voltage value = the current output voltage of the energy storage module 110 + 0.5V. The preset charging voltage value increases as the voltage of the energy storage module 110 increases and decreases as the voltage of the energy storage module 110 decreases, in order to avoid large current surges to the energy storage module 110 during charging and to achieve complete charging of the energy storage module 110.

[0035] In one embodiment, the charging and discharging module 130 includes: a charging unit 132, which is electrically connected to the control module 120, the voltage conversion module 300, and the energy storage module 110 respectively; the control module 120 is further configured to send a charging control signal to the charging unit 132 if the current output voltage of the voltage conversion module 300 is greater than or equal to the preset charging voltage value; the charging unit 132 is configured to turn on when it receives the charging control signal, so that the energy storage module 110 is electrically connected to the voltage conversion module 300.

[0036] In this embodiment, when the control module 120 detects that the current output voltage of the voltage conversion module 300 is greater than or equal to a preset charging voltage value, it sends a charging control signal to the charging unit 132. Upon receiving the charging control signal, the charging unit 132 is turned on, establishing a path between the energy storage module 110 and the voltage conversion module 300. At this time, the electrical energy output by the voltage conversion module 300 can flow to the energy storage module 110 through the charging unit 132, thus charging the energy storage module 110. Specifically, the charging unit 132 includes, as follows: Figure 4 The bidirectional topology circuit shown.

[0037] Figure 4 In the circuit shown, BUS_IN+ and BUS_IN- represent the positive and negative terminals of the voltage input to the voltage conversion module 300, respectively, and BAT_OUT+ and BAT_OUT- represent the positive and negative terminals of the voltage output to the energy storage module 110, respectively. Figure 4 The circuit shown operates as follows: MOS switch Q12 is normally open during normal operation. Q8 and Q10 are a pair of mutually exclusive PWM transistors, as are Q9 and Q11. Assuming the PWM duty cycle of Q9 is D1 and the duty cycle of Q8 is D2, the voltage output to the energy storage module 110 equals the output voltage of the voltage conversion module 300 multiplied by (D1 / (1-D2)). Let D = (D1 / (1-D2)). Then, when D < 1, the charging unit 132 operates with a step-down voltage, and when D > 1, the charging unit operates with a step-up voltage.

[0038] Furthermore, after the charging unit 132 is turned on, it will automatically switch between boost and buck modes through a switching network composed of built-in MOSFETs and other components based on the acquired second voltage adjustment signal: if the output voltage of the voltage conversion module 300 is lower than the current voltage of the energy storage module 110, it will switch to boost mode; if it is higher, it will switch to buck mode, and finally stabilize the voltage output to the energy storage module 110 near the preset charging voltage value (usually the current voltage of the energy storage module 110 + 0.5V) to ensure charging efficiency and safety.

[0039] In one embodiment, the second voltage adjustment signal includes a second boost signal or a second buck signal; the control module 120 is further configured to send the second boost signal to the charging unit 132 if the current output voltage of the energy storage module 110 is greater than or equal to the current output voltage of the voltage conversion module 300; and to send the second buck signal to the charging unit 132 if the current output voltage of the energy storage module 110 is less than the current output voltage of the voltage conversion module 300.

[0040] In this embodiment, when the output voltage of the voltage conversion module 300 is greater than or equal to the preset charging voltage value, the control module 120 compares the current output voltage of the energy storage module 110 with the current output voltage of the voltage conversion module 300. If the current output voltage of the energy storage module 110 is greater than or equal to the current output voltage of the voltage conversion module 300, it indicates that the output voltage of the voltage conversion module 300 needs to be increased to complete the charging of the energy storage module 110, and the control module 120 sends a second boost signal to the charging unit 132. If the voltage of the energy storage module 110 is less than the voltage of the voltage conversion module 300, the output voltage of the voltage conversion module 300 needs to be reduced to match the charging requirements of the energy storage module 110, and the control module 120 sends a second buck signal. Through this voltage comparison-based signal control, the charging unit 132 can accurately switch operating modes to ensure that the output voltage is stable near the preset charging voltage value, thereby achieving efficient and safe charging of the energy storage module 110.

[0041] It should be further noted that the voltage intelligent control system 100 provided in this application embodiment also has the function of adapting to the differences in peak and off-peak electricity consumption periods in different regions. It can match the control requirements of different time periods by pre-setting system parameters. Specifically, during off-peak electricity consumption periods, the control module 120 will control the charging unit 132 to draw power from the voltage conversion module 300 according to preset parameters to replenish the energy storage module 110; while during peak electricity consumption periods, the control module 120 will control the discharging unit 131 to automatically adjust the output voltage of the energy storage module 110 according to preset parameters, so that the sodium-ion battery releases energy to the load 400.

[0042] The voltage intelligent control system provided in this application embodiment includes: an energy storage module, a control module, and a charging / discharging module. The energy storage module is electrically connected to both the control module and the charging / discharging module. The charging / discharging module is also electrically connected to the control module, a voltage conversion module, and a load. The control module is also electrically connected to the voltage conversion module. The voltage conversion module is electrically connected to both the mains power system and the load. The voltage conversion module is used to obtain the mains voltage from the mains power system, convert the mains voltage into a target voltage, and output it to the load, thereby enabling the mains power system to supply power to the load. The control module is used to obtain the target voltage from the mains power system. If the current output voltage of the voltage conversion module is less than a preset discharge voltage value, the current output voltage of the energy storage module is obtained. Based on the current output voltage of the energy storage module and the preset discharge voltage value, a first voltage adjustment signal is sent to the charge / discharge module, where the preset discharge voltage value is less than the target voltage. The charge / discharge module, upon receiving the first voltage adjustment signal, obtains the current output voltage of the energy storage module, adjusts the current output voltage of the energy storage module to the preset discharge voltage value, and then outputs it to the load, thereby enabling the energy storage module to supply power to the load. This application achieves simultaneous switching between mains power and energy storage module power supply, and solves the problem of mismatch between the wide voltage range of the energy storage module and the operating voltage of the load by adjusting the output voltage of the energy storage module, thus improving the energy utilization rate of the energy storage module.

[0043] Example 2 In addition, please see Figure 5 , Figure 5 A schematic flowchart of a voltage intelligent control method provided in an embodiment of this application is shown. The method is applied to the voltage intelligent control system 100 described in Embodiment 1 and includes steps S510 to S520.

[0044] In step S510, the control module 120 obtains the current output voltage of the voltage conversion module 300. If the current output voltage of the voltage conversion module 300 is less than the preset discharge voltage value, the control module 120 obtains the current output voltage of the energy storage module 110 and sends a first voltage adjustment signal to the charge and discharge module 130 based on the current output voltage of the energy storage module 110 and the preset discharge voltage value. The preset discharge voltage value is less than the target voltage.
