Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.
At present, the power supply mode of a base station is that when the mains supply is normal, the mains supply supplies power to the base station, when the mains supply is powered off, the storage battery supplies power to the base station, and when the mains supply is powered off for a long time, an oil engine supplies power to the base station to protect the storage battery.
Because the storage battery is adopted to supply power to the base station when the commercial power is cut off, the storage battery can generate pollution in each link of production, use, elimination, scrapping and the like. And the life of the storage battery is short, for example, the life of the lithium iron phosphate battery is about 5 to 6 years, so that the cost of purchasing the lithium iron phosphate battery is huge for operators. In addition, in areas with good utility power, the batteries are always in an idle state, resulting in waste and no loss of the batteries.
Therefore, the storage battery is polluted in all links such as production, use and scrapping elimination, the service life of the storage battery is short, and the cost is high.
In addition, in areas with good mains supply, the storage battery is always in an idle state, so that the storage battery is wasted and lost without cause; in some places such as hospitals or nursing homes, which have requirements on noise, the power generation by the oil engine is not suitable when the mains supply is in a long-term outage.
In view of the above problems, the present application provides a power supply device, which supplies power to a communication device through a metal-air battery when a commercial power is cut off and an output parameter of the metal-air battery meets a preset condition. Compared with a storage battery, the metal-air battery has the advantages of small pollution, long service life and low cost, so that the scheme of the application can reduce the pollution of the power supply equipment, prolong the service life of the power supply equipment and reduce the cost of the power supply equipment.
In addition, the main source of noise of the metal air battery is the radiator exhaust device, and the noise is small relative to the oil engine, so that the power supply equipment provided by the application can be used for supplying power to the communication equipment in places where the oil engine is inconvenient to use for power supply.
The power supply equipment is used for supplying power to the communication equipment.
Alternatively, the communication device may be a base station.
As shown in fig. 1, the power supply apparatus 10 provided by the present application includes a control unit 11, a metal-air battery 12, and an energy storage unit 13. The control unit 11 is connected with the metal-air battery 12 and the energy storage unit 13, respectively.
And the control unit 11 is used for controlling the metal-air battery 12 to be started and controlling the energy storage unit 13 to supply power to the communication equipment under the condition that the mains supply is disconnected.
Alternatively, the metal-air battery 12 may be a zinc-air battery, an aluminum-air battery, a magnesium-air battery, a lithium-air battery, a calcium-air battery, or an iron-air battery, etc.
Preferably, the metal-air battery 12 is an aluminum-air battery.
The aluminum-air battery uses high-purity aluminum as a negative electrode, oxygen as a positive electrode, and potassium hydroxide (KOH) or sodium hydroxide (NaOH) aqueous solution as an electrolyte. Aluminum takes up oxygen in the air, a chemical reaction is generated when the battery is discharged, and the aluminum and the oxygen are reacted and converted into aluminum oxide.
Optionally, the metal-air battery 12 includes an electrolyte tank, a working fluid tank, a cleaning fluid tank, a waste fluid tank, and at least one cell stack.
The stack may be a metal, such as aluminum. The electrolyte tank and the working solution tank are used for storing electrolyte. The cleaning solution tank is used for storing cleaning solution, and the cleaning solution is used for cleaning the galvanic pile. The waste liquid tank is used for collecting cleaning liquid after cleaning or electrolyte after reaction.
When the metal air battery 12 is started, the electrolyte tank provides electrolyte for the working liquid tank, the working liquid tank provides electrolyte for at least one galvanic pile and performs chemical reaction inside the galvanic pile, chemical energy is converted into electric energy, and the electric energy is supplied to communication equipment through a direct current/direct current (DC/DC) module.
When the metal-air battery 12 is closed, the electrolyte tank is in a shutdown state, and liquid is not supplied to the working liquid tank; the working liquid box and the cleaning liquid box are in a shutdown state, the working liquid box does not provide electrolyte for the galvanic pile, and the cleaning liquid box does not provide cleaning liquid for the galvanic pile for cleaning.
Alternatively, the electrolyte may be an aqueous solution of potassium hydroxide (KOH) or sodium hydroxide (NaOH). The cleaning fluid may be water or glycerin.
The metal-air battery 12 has little environmental pollution in the aspects of production, use and elimination of scrapping treatment, and the metal-air battery reaction product arranged in the metal-air battery 12 can be recycled, so that the operation cost can be effectively reduced. The service life of the metal-air battery 12 is long, for example, the service life of the aluminum-air battery is generally more than ten years, only the starting energy storage unit needs to be replaced midway, and the purchasing cost can be effectively reduced.
In addition, the main source of noise of the metal air battery is the radiator exhaust device, and the noise is small relative to the oil engine, so that the power supply equipment provided by the application can be used for supplying power to the communication equipment in places where the oil engine is inconvenient to use for power supply.
Optionally, the control unit 11 controls the metal-air battery 12 to start when the utility power is cut off, and may control the electrolyte in the electrolyte tank of the metal-air battery 12 to enter the working fluid tank of the metal-air battery 12 and control the electrolyte in the working fluid tank of the metal-air battery 12 to enter the stack when the utility power is cut off by the control unit 11, so that the electrolyte reacts with the stack to generate electric energy. When the control unit 11 controls the metal-air battery 12 to start, a certain time (i.e. a transition time of the metal-air battery 12) is required until the output parameter of the metal-air battery 12 meets a preset condition (i.e. the metal-air battery 12 can meet the power supply requirement of the communication device), and the metal-air battery 12 cannot supply power to the communication device during the transition time.
And the energy storage unit 13 is used for supplying power to the communication equipment under the condition that the mains supply is disconnected and the output parameters of the metal-air battery do not meet preset conditions.
That is, the starting time of the power storage unit 13 supplying power to the communication device is the mains supply off time, and the ending time of the power storage unit 13 supplying power to the communication device is the time that the metal-air battery 12 can supply power to the communication device, that is, the power storage unit 13 supplies power to the communication device in the transition time of the metal-air battery 12, so the capacity of the power storage unit 13 may be a small-capacity power storage unit.
Alternatively, the energy storage unit 13 may be a battery. The energy storage unit 13 is, for example, a lithium iron phosphate battery.
Because the energy storage unit 13 is used for transitive power supply to the communication equipment, the energy storage unit can be a small-capacity energy storage unit, the energy storage unit 13 is a lithium iron phosphate battery, and the lithium iron phosphate battery can be a small-capacity lithium iron phosphate battery, so that the environmental pollution is small when the small-capacity lithium iron phosphate battery is produced, used and discarded.
The output parameter of the metal-air battery 12 satisfying the preset condition includes that the output parameter of the metal-air battery 12 satisfies a rated parameter of the communication device.
Optionally, the output parameters of the metal-air battery 12 include voltage, current or power. The rated parameters of the communication device include a rated voltage of the communication device, a rated current of the communication device, a rated power of the communication device, or the like.
For example, the output parameter of the metal-air battery 12 satisfies the preset condition that the output voltage of the metal-air battery 12 satisfies the rated voltage of the communication device.
And the control unit 11 is further configured to control the energy storage unit 13 to stop supplying power to the communication device when the output parameter of the metal-air battery 12 meets a preset condition.
And the control unit 11 is further configured to control the metal-air battery 12 to be turned off and control the mains supply to supply power to the communication device under the condition that the mains supply is normal.
Optionally, the control unit 11 controls the metal-air battery 12 to be turned off under the normal condition of the utility power, and may control the electrolyte in the stack of the metal-air battery 12 to enter the working fluid tank and control the electrolyte in the stack of the metal-air battery 12 to be separated from the stack under the normal condition of the utility power by the control unit 11, so as to stop the electrolyte and the stack from reacting to generate electric energy.
Under the condition that the commercial power is normal, the control unit 11 controls the commercial power to supply power to the communication device, and at this time, the energy storage unit 13 may be in a charging state or a backup state according to the capacity of the energy storage unit. For example, when the utility power is normal, if the capacity of the energy storage unit 13 is less than or equal to a first preset threshold, the energy storage unit 13 may be charged through the utility power, and if the capacity of the energy storage unit 13 is greater than or equal to a second preset threshold, the energy storage unit 13 stops being charged, and the energy storage unit 13 is in a backup state.
Optionally, the first preset threshold and the second preset threshold may be determined according to actual conditions, which is not limited in this application.
The application provides a power supply unit, under the circumstances of commercial power disconnection, control metal-air battery starts to control the energy storage unit and supply power to communication equipment, under the circumstances of metal-air battery's output parameter satisfies the preset condition, control the energy storage unit and stop supplying power to communication equipment, under the circumstances of metal-air battery's output parameter satisfies the preset condition promptly, by metal-air battery to communication equipment power supply.
The metal-air battery has small environmental pollution in the aspects of production, use and elimination of scrapping treatment, and the reaction product of the metal-air battery built in the metal-air battery can be recycled, so that the operation cost can be effectively reduced. The service life of the metal-air battery is long, for example, the service life of the aluminum-air battery is generally more than ten years, only the starting energy storage unit needs to be replaced midway, and the purchasing cost can be effectively reduced.
Compare in prior art when the commercial power outage by the battery for the basic station power supply, supply power to communication equipment through the metal-air battery in this application, the metal-air battery compares that the battery pollutes for a short time, longe-lived and with low costs, consequently, the scheme of this application can reduce power supply unit's pollution, improve power supply unit's life-span and can reduce power supply unit's cost.
In addition, the main source of noise of the metal air battery is the radiator exhaust device, and the noise is small relative to the oil engine, so that the power supply equipment provided by the application can be used for supplying power to the communication equipment in places where the oil engine is inconvenient to use for power supply.
