[0027] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0028] like Figure 1 and Figure 2 As shown, the embodiment of the present disclosure proposes a power supply system for a base station 4, comprising: a switching power supply 3, a standby power supply 1 and an emergency power supply 2, the power supply end of the switching power supply 3 is connected to the power supply end of the power-consuming equipment 41 of the base station 4, the standby power supply 1 comprises: a first convergence module 11 and a plurality of first batteries 12, the charging and discharging ends of the first batteries 12 are connected to the shunt end of the first convergence module 11, and the convergence end of the first convergence module 11 is connected to the DC power supply end of the switching power supply 3, the emergency power supply 2 comprises: a second convergence module 21, an inverter 22 and a plurality of second batteries 23, the charging and discharging ends of the second batteries 23 are connected to the shunt end of the second convergence module 21, the convergence end of the second convergence module 21 is respectively connected to the shunt end of the first convergence module 11 and the power supply end of the inverter 22, and the power supply end of the inverter 22 is connected to the AC power supply end of the switching power supply 3.

[0029] It can be understood that, since the charging and discharging end of the second battery 23 is connected to the shunt end of the second confluence module 21, the DC power output by the plurality of second batteries 23 can be converged into the second confluence module 21, and since the charging and discharging end of the first battery 12 is connected to the shunt end of the first confluence module 11, the DC power output by the plurality of first batteries 12 and the DC power confluenced by the second confluence module 21 can be converged into the first confluence module 11. At the same time, since the confluence end of the first confluence module 11 is connected to the DC power supply end of the switching power supply 3, The DC power converged by the first convergence module 11 can be used to power the electrical equipment 41 in the base station 4 under the power conversion of the switching power supply 3; and since the convergence end of the second convergence module 21 is connected to the power end of the inverter 22, and the power end of the inverter 22 is connected to the AC power end of the switching power supply 3, the DC power converged by the second convergence module 21 can be converted into AC power by the inverter 22 and transmitted to the switching power supply 3, thereby utilizing the power conversion of the switching power supply 3 to power the electrical equipment 41 in the base station 4.

[0030] Therefore, by utilizing the plurality of first batteries 12 in the permanent power supply 1 as the permanent backup power supply for the electrical equipment 41 in the base station 4, and utilizing the plurality of second batteries 23 in the emergency power supply 2 as the emergency backup power supply for the electrical equipment 41 in the base station 4, it is possible to stably realize the power supply guarantee of the base station 4, thereby meeting the communication demand. Moreover, the power supply of the first battery 12 and the second battery 23 does not cause environmental pollution problems such as smoke, odor, and noise. At the same time, the maintenance and raw material usage costs are relatively low, which can meet the low-pollution and low-cost power supply guarantee needs of the base station 4.

[0031] It should be noted that the standing power supply 1 is used as a permanent backup power supply for the electrical equipment 41 in the base station 4, that is, the standing power supply 1 is bound to the base station 4, and each base station 4 is configured with a corresponding standing power supply 1, for example: the standing power supply 1 is arranged inside the computer room 43 of the base station 4; the emergency power supply 2 is used as an emergency backup power supply for the electrical equipment 41 in the base station 4, that is, the emergency power supply 2 and the base station 4 are flexibly configured, for example: the emergency power supply 2 is arranged outside the computer room 43 of the base station 4.

[0032] Among them, when the city power is cut off, the standing power supply 1 and the emergency power supply 2 cooperate to supply power to the power equipment 41 of the base station 4. Specifically, when the power supply capacity of the standing power supply 1 is not less than the power demand of the power equipment 41 in the base station 4, only the standing power supply 1 supplies power to the power equipment 41 of the base station 4; when the power supply capacity of the standing power supply 1 is less than the power demand of the power equipment 41 in the base station 4, the emergency power supply 2 cooperates with the standing power supply 1 to supply power to the power equipment 41 of the base station 4. Thus, while meeting the power demand of the base station 4, the power supply guarantee of the base station 4 is made more flexible, thereby greatly reducing the power supply guarantee cost of the base station 4.

[0033] The first battery 12 in the standby power supply 1 is used for charging and storing energy and discharging and supplying energy. Since the first battery 12 in the standby power supply 1 is used as a resident standby power supply for the power-consuming equipment 41 in the base station 4, the capacity of the BBU (Battery Back-Up, standby battery 42) of the base station 4 can be expanded by using the first battery 12. Moreover, when the power-consuming equipment 41 of the base station 4 is in a normal power supply state, the first battery 12 is in a standby state. If the power level of the first battery 12 is lower than a preset threshold, it can be charged through devices such as the first convergence module 11. The number and specific type of the first battery 12 can be set according to actual needs and there is no restriction on this. For example, the first battery 12 can be a high-performance lithium iron phosphate battery, the number of the first batteries 12 can be ten, the first battery 12 can be 500AH in capacity, and the first battery 12 is subjected to force buffering during installation. The standby power supply 1 has undervoltage, overvoltage, overtemperature, overcurrent and other protection functions and automatic alarm functions for the first battery 12.

[0034] The first bus module 11 in the standby power supply 1 is used for the busing of direct current output by multiple first batteries 12 and the direct current output by the second bus module 21. The specific type of the first bus module 11 can be set according to actual needs and is not limited to this. For example, the first bus module 11 can be a differential battery group sharing manager (dBMS), which is also called a combiner. It has a busbar for busing. At the same time, the first bus module 11 can realize mixed connection of different types of batteries, and use multiple switches to realize functions such as synchronous discharge, asynchronous discharge, independent charging, and sequential charging.

[0035] The second battery 23 in the emergency power supply 2 is used for charging and storing energy and discharging and supplying energy. Since the second battery 23 in the emergency power supply 2 is used as an emergency backup power supply for the electrical equipment 41 in the base station 4, the second battery 23 can be used to expand the BBU capacity of the base station 4, or directly used for backup power supply of the electrical equipment 41 in the base station 4. Moreover, when the electrical equipment 41 of the base station 4 is in a normal power supply state, the second battery 23 is in a standby state. If the power level of the second battery 23 is lower than a preset threshold, it can be charged through devices such as the second convergence module 21. The number and specific type of the second battery 23 can be set according to actual needs and there is no restriction on this. For example, the second battery 23 can be a high-performance lithium iron phosphate battery. The second battery 23 can be divided into multiple groups, each with five cells. The second battery 23 can have a capacity of 500AH. The second battery 23 is subjected to force buffering during installation. The emergency power supply 2 has undervoltage, overvoltage, overtemperature, overcurrent and other protection functions and automatic alarm functions for the second battery 23.

[0036] The second bus module 21 in the emergency power supply 2 is used for busing the DC power output by multiple second batteries 23. The specific type of the second bus module 21 can be set according to actual needs and is not limited to this. For example, the second bus module 21 can be a differential battery group sharing manager (dBMS), which has a busbar for busing. At the same time, the second bus module 21 can realize mixed connection of different types of batteries, and use multiple switches to realize synchronous discharge, asynchronous discharge, independent charging, sequential charging and other functions.

[0037] The inverter 22 in the emergency power supply 2 is used to convert the DC power output by the second junction module 21 into AC power. The specific type of the inverter 22 can be set according to actual needs and is not limited to this. For example, the power of the inverter 22 is 15kw, and the inverter 22-48V DC is converted into 220V AC.

[0038] The switching power supply 3 is used for converting electric energy so that the AC power at its AC power supply end and the DC power at its DC power supply end can meet the power demand of the power-consuming equipment 41 in the base station 4. The specific type of the switching power supply 3 can be set according to actual needs and is not limited to this. For example, the switching power supply 3 has an inverter function of -48V DC to 220AC.

[0039] like Figure 2 As shown, in some embodiments, the emergency power supply 2 also includes: a switching switch 24, the switching switch 24 is connected in series between the bus end of the second bus module 21 and the shunt end of the first bus module 11 and between the bus end of the second bus module 21 and the power end of the inverter 22, and the power end of the switching switch 24 is connected to the bus end of the second bus module 21, the DC power supply end of the switching switch 24 is connected to the shunt end of the first bus module 11, and the AC power supply end of the switching switch 24 is connected to the power supply end of the inverter 22; wherein, the power supply end of the switching switch 24 and the DC power supply end are conductive, or the power supply end of the switching switch 24 and the AC power supply end are conductive.

[0040] It can be understood that since the power supply end of the switching switch 24 is connected to the bus end of the second bus module 21, and the DC power supply end of the switching switch 24 is connected to the shunt end of the first bus module 11, and the AC power supply end of the switching switch 24 is connected to the power supply end of the inverter 22, when the power supply end and the DC power supply end of the switching switch 24 are turned on, the DC power output by the multiple second batteries 23 can be transmitted to the first bus module 11 after being converged by the second bus module 21, thereby realizing the DC output of the emergency power supply 2; when the power supply end and the AC power supply end of the switching switch 24 are turned on, the DC power output by the multiple second batteries 23 can be transmitted to the inverter 22 after being converged by the second bus module 21, thereby realizing the AC output of the emergency power supply 2 by utilizing the DC-AC conversion of the inverter 22.

[0041] Therefore, through the switching control of the switching switch 24, the emergency power supply 2 can be flexibly switched between the DC output mode and the AC output mode, thereby making the use of the emergency power supply 2 more efficient and convenient.

[0042] It should be noted that the switching switch 24 is used to switch between the path between the bus end of the second bus module 21 and the shunt end of the first bus module 11 and the path between the bus end of the second bus module 21 and the power supply end of the inverter 22. The specific type of the switching switch 24 can be set according to actual needs and is not limited to this.

[0043] like Figure 3As shown, in some embodiments, the emergency power supply 2 also includes: a DC circuit breaker 25, which is connected in series between the power supply end of the switching switch 24 and the bus terminal of the second bus terminal 21, and the power supply end of the DC circuit breaker 25 is connected to the bus terminal of the second bus terminal 21, and the power supply end of the DC circuit breaker 25 is connected to the power supply end of the switching switch 24.

[0044] It can be understood that since the power supply end of the DC circuit breaker 25 is connected to the bus end of the second bus module 21, and the power supply end of the DC circuit breaker 25 is connected to the power supply end of the switching switch 24, the emergency power supply 2 can use the DC circuit breaker 25 to achieve on-off control between the bus end of the second bus module 21 and the power supply end of the switching switch 24, as well as circuit overload, short circuit and other protections, thereby ensuring stable DC output and AC output of the emergency power supply 2.

[0045] It should be noted that the DC circuit breaker 25 is used to control the on / off of the path between the bus terminal of the second bus module 21 and the power terminal of the switching switch 24, as well as the safety protection of the circuit. The specific type of the DC circuit breaker 25 can be set according to actual needs and is not limited to this.

[0046] like Figure 3 As shown, in some embodiments, the AC circuit breaker 26 is connected in series between the power supply end of the inverter 22 and the AC power supply end of the switching power supply 3, and the power supply end of the AC circuit breaker 26 is connected to the power supply end of the inverter 22, and the power supply end of the AC circuit breaker 26 is connected to the AC power supply end of the switching power supply 3.

[0047] It can be understood that since the power supply end of the AC circuit breaker 26 is connected to the power supply end of the inverter 22, and the power supply end of the AC circuit breaker 26 is connected to the AC power supply end of the switching power supply 3, the emergency power supply 2 can use the AC circuit breaker 26 to achieve on-off control between the power supply end of the inverter 22 and the AC power supply end of the switching power supply 3, as well as circuit overload, short circuit and other protections, thereby ensuring stable AC output of the emergency power supply 2.

[0048] It should be noted that the AC circuit breaker 26 is used to control the on / off of the path between the power supply end of the inverter 22 and the AC power supply end of the switching power supply 3, as well as the safety protection of the circuit. The specific type of the AC circuit breaker 26 can be set according to actual needs and is not limited to this.

[0050] It can be understood that since the first male connector 13 is connected to the charging and discharging end of the first battery 12, and the first female socket 14 is arranged at the shunt end of the first convergence module 11, the first male connector 13 and the first female socket 14 can achieve connection and power transmission between the charging and discharging end of the first battery 12 and the shunt end of the first convergence module 11 when plugged in, thereby avoiding complicated wiring. While the first battery 12 can provide stable power supply to the electrical equipment 41 in the base station 4, the first battery 12 has a higher disassembly and assembly efficiency, thereby making the use of the standby power supply 1 more flexible and convenient.

[0051] It should be noted that the first male connector 13 and the first female connector 14 are used for plug-in electrical connection to realize the power transmission between the charging and discharging end of the first battery 12 and the shunt end of the first convergence module 11. The specific types of the first male connector 13 and the first female connector 14 can be set according to actual needs and are not limited to this. For example, the first male connector 13 and the first female connector 14 can be Anderson interfaces. The first male connector 13 is connected to the charging and discharging end of the first battery 12 by a wire, and the connection method is determined according to the type of battery, for example: screw connection, connector connection, etc. Safety and waterproof treatment are performed between the first male connector 13 and the first female connector 14.

[0052] In addition to the first male connector 13 and the first female connector 14, the first confluence module 11 may also be provided with a switch for controlling the on / off of the circuit, a display panel for displaying the power parameters of the first battery 12, a 485 communication interface for communication, and the like.

[0054] It can be understood that since the second male connector is connected to the charging and discharging ends of the second battery 23, and the second female connector is arranged at the shunt end of the second convergence module 21, the second male connector and the second female connector can be connected and the power transmission between the charging and discharging ends of the second battery 23 and the shunt end of the second convergence module 21 can be achieved when the second male connector and the second female connector are plugged in, thereby avoiding complicated wiring. While the second battery 23 can provide stable power supply to the electrical equipment 41 in the base station 4, the second battery 23 has a higher disassembly and assembly efficiency, thereby making the use of the emergency power supply 2 more flexible and convenient.

[0055] It should be noted that the second male connector and the second female connector are used for plug-in electrical connection to realize the power transmission between the charging and discharging end of the second battery 23 and the shunt end of the second convergence module 21. The specific types of the second male connector and the second female connector can be set according to actual needs and are not limited to this. For example, the second male connector and the second female connector can be Anderson interfaces, and the second male connector is connected to the charging and discharging end of the second battery 23 by a wire, and the connection method is determined according to the type of battery, for example: screw connection, connector connection, etc. The second male connector and the second female connector are treated for safety and waterproofness.

[0057] like Figure 1 and Figure 2 As shown, in some embodiments, the shunt end of the first confluence module 11 is connected to the charging and discharging end of the backup battery 42 of the power-consuming device 41 .

[0058] It can be understood that since the shunt end of the first convergence module 11 is connected to the charging and discharging end of the backup battery 42 of the electrical equipment 41 in the base station 4, the first convergence module 11 can realize the convergence of the DC power output by the backup battery 42, the DC power output by the first battery 12 and the DC power output by the second battery 23, thereby facilitating the centralized management of the backup power supply and making the use of the power supply system more efficient and convenient.

[0059] It should be noted that, in the relevant embodiments, the charging and discharging ends of the backup battery 42 of the electrical equipment 41 in the base station 4 are directly connected to the DC power supply end of the switching power supply 3 to ensure the power supply of the base station 4. In the present embodiment, the backup battery 42 of the electrical equipment 41 in the base station 4 is connected to the DC power supply end of the switching power supply 3 using the first convergence module 11, and the backup battery 42, the first battery 12 and the second battery 23 simultaneously ensure the power supply of the electrical equipment 41 in the base station 4.

[0060] The specific type of the backup battery 42 can be set according to actual needs and is not limited to this. For example, the backup battery 42 can be a lead-acid battery.

[0062] It can be understood that, since the second junction module 21 and the inverter 22 are respectively arranged in the first emergency cabinet 27, and part of the second battery 23 is arranged in the first emergency cabinet 27, the second junction module 21, the inverter 22 and part of the second battery 23 can be centrally arranged in the first emergency cabinet 27, so as to realize the flexible arrangement and stable power supply of the emergency power supply 2 by utilizing the integrated protection of the first emergency cabinet 27; at the same time, since the remaining second batteries 23 are arranged in the second emergency cabinet 28, the remaining batteries can be centrally arranged in the second emergency cabinet, so as to realize the flexible arrangement and stable power supply of multiple second batteries 23 by utilizing the integrated protection of the second emergency cabinet 28. Therefore, through the cooperation of the first emergency cabinet 27 and at least one second emergency cabinet 28, the use of the emergency power supply 2 is more flexible and convenient.

[0063] It should be noted that the first emergency cabinet 27 is used to integrate the second convergence module 21, the inverter 22 and part of the second battery 23 as the power supply and energy storage part of the emergency power supply 2. The specific type of the first emergency cabinet 27 can be set according to actual needs and is not limited to this. For example, the first emergency cabinet 27 is a cabinet structure close to a rectangular parallelepiped. The first emergency cabinet 27 has multiple wiring ports, some of which are used to connect to the wiring ports of the second emergency cabinet 28 using wires, connectors, etc., so as to use the wiring ports to realize the electrical connection between the second battery 23 in the second emergency cabinet 28 and the second convergence module 21 in the first emergency cabinet 27, some of which are used to connect to the distribution cabinet in the machine room 43 using wires, connectors, etc., so as to use the wiring ports and the distribution cabinet to realize the electrical connection between the inverter 22 and the switching power supply 3, and some of the wiring ports are used to connect to the wiring ports on the standing cabinet 15 in the standing power supply 1 using wires, connectors, etc., so as to use the wiring ports to realize the electrical connection between the second convergence module 21 in the first emergency cabinet 27 and the first convergence module 11 in the standing cabinet 15.
