Detailed Description
The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a circuit structure schematic diagram, including: the power supply switching device 10, the load 20, the power supply circuit 30, and optionally, the ac power distribution equipment 40 and the switching power supply 50. Wherein, the power switching device 10 includes: the controller 11, the metal fuel cell 12, the lithium battery 13, the lead-acid battery 14, the first switch 15, the second switch 16, the third switch 17, and the voltage conversion module 18, wherein the metal fuel cell 13 may be an aluminum air battery or the like.
As shown in fig. 2, an embodiment of the present application provides a schematic structural diagram of a metal fuel cell 12, where the metal fuel cell 12 includes: electrolyte conveying unit 121, oxygen supply unit 122, battery reaction unit 123, wind-heat integrated management unit 124, and electrolyte storage unit 125.
The electrolyte delivery unit 121 delivers the electrolyte stored in the electrolyte storage unit 125 to the battery reaction unit 123, the oxygen supply unit 122 is used for delivering oxygen to the battery reaction unit 123, and the active metal of the anode in the battery reaction unit 123 is used for generating voltage under the action of the electrolyte and the oxygen. The wind-heat integrated management unit 124 is used for monitoring and managing ventilation and heat dissipation in the reaction of the battery reaction unit 123, and the electrolyte storage unit 125 is used for storing electrolyte.
The controller 11 can obtain information of the voltage and capacity of the lithium battery 13, the voltage and capacity of the lead-acid storage battery 14, the power failure time of the commercial power, and the like, and is used for executing the power switching method described below.
Examples 1,
The controller 11 may perform a power switching method, as shown in fig. 3, including:
and S301, when the mains supply is powered off, indicating the first switch to be closed and the third switch to be disconnected, and enabling the lithium battery to be connected into the power supply circuit.
The repeated charge and discharge performance of the lithium battery 13 is superior to that of the lead-acid battery 14, and it takes a certain time for the metal fuel cell 12 to react to be able to supply power to the load 20. Therefore, when the mains supply is powered off, the lithium battery 13 is connected to the power supply circuit 30 to supply power to the load 20, so that the energy of the lead-acid battery 14 and the metal fuel battery 12 can be prevented from being consumed due to instantaneous interruption of the mains supply caused by lightning stroke and the like, the service life of the lead-acid battery can be prevented from being influenced, and meanwhile, the situation of inter-group circulation caused by inconsistent voltage of the lead-acid battery 14 and the lithium battery 13 due to power failure can be avoided.
And S302, when the voltage, the capacity or the commercial power outage time of the lithium battery meets the conditions, the first switch is indicated to be disconnected, the third switch is indicated to be closed, the lithium battery is disconnected from the power supply circuit, and the lead-acid storage battery is connected into the power supply circuit.
After the lithium battery 13 supplies power to the load 20 for a certain time, in order to avoid that the output of the lithium battery 13 cannot support the normal operation of the load 20, the controller 11 may obtain information such as the voltage and the capacity of the lithium battery 13, so as to determine whether the current voltage and the capacity of the lithium battery 13 or the power failure time of the commercial power supply meet the conditions. When the voltage, the capacity or the commercial power outage time of the lithium battery 13 meets the conditions, it is judged that the current output of the lithium battery cannot support the normal operation of the load 20, the lithium battery 13 is disconnected from the power supply circuit 30, and the lead-acid storage battery 14 is connected to the power supply circuit 30 to supply power to the load 20.
Optionally, as shown in fig. 4, when the voltage of the lithium battery 13 is less than or equal to the first voltage, the capacity is less than or equal to the first capacity, or the utility power outage time is greater than or equal to the first time, the first switch 15 is indicated to be opened, the third switch 17 is indicated to be closed, so that the lithium battery 13 is disconnected from the power supply circuit 30, and the lead-acid battery 14 is connected to the power supply circuit 30.
The user can select and adjust corresponding parameters according to the actual application scene to judge the current output state of the lithium battery 13, if in a cold region, the charge-discharge efficiency of the lithium battery 13 can be reduced to a certain extent, and at the moment, the first time is reduced according to the actual situation, or the commercial power outage time is not used as the judgment condition.
For example, the first voltage may be a normal operating voltage 48V of the load 20, and when the voltage of the lithium battery 13 is less than 48V, the first switch 15 is instructed to be opened, the third switch 17 is instructed to be closed, so that the lithium battery 13 is disconnected from the power supply circuit 30, the lead-acid storage battery 14 is connected to the power supply circuit 30, and the lead-acid storage battery 14 supplies power to the load 20.
Optionally, when the utility power is recovered, if the voltage of the lithium battery 13 is greater than the first voltage and the capacity is greater than the first capacity, or the utility power outage time is less than the first time, the first switch 15 is indicated to be closed, so that the lithium battery 13 is connected to the power supply circuit 30, and the lithium battery 13 is charged through the power supply circuit 30.
For example, the first time may be 30 minutes, and in the case that the power supply is restored after the mains power fails for 10 minutes, the controller 11 may obtain that the mains power failure time is 10 minutes less than the first time, determine that the lithium battery 13 has a certain consumption but a small consumption, instruct the first switch 15 to be closed, and charge the lithium battery 13 through the power supply circuit 30.
Optionally, when the duration that the charging current of the lithium battery 13 is greater than the preset current exceeds the preset time, or the duration that the voltage of the lithium battery 13 is greater than the third voltage exceeds the preset time, or the duration that the capacity of the lithium battery 13 is greater than the third capacity exceeds the preset time, the third switch 17 is indicated to be closed, so that the lithium battery 13 and the lead-acid storage battery 14 are connected to the power supply circuit 30 to be in a floating charge state.
When the charging current, voltage or capacity of the lithium battery 13 meets the conditions, the lithium battery 13 is judged to be fully charged, the third switch 17 is closed at the moment, the lithium battery 13 and the lead-acid storage battery 14 are in a floating charging state, and the loss of local action of the lithium battery 13 and the lead-acid storage battery 14 is compensated through a small amount of current, so that the lithium battery 13 and the lead-acid storage battery 14 can be always kept in the charging meeting state without overcharging.
And S303, when the voltage, the capacity or the mains supply power failure time of the lead-acid storage battery meets the conditions, the third switch is indicated to be switched off, and the first switch and the second switch are switched on, so that the lithium battery and the metal fuel battery are connected to the power supply circuit.
After the lead-acid storage battery 14 supplies power for a certain time, whether the voltage, the capacity or the commercial power outage time of the lead-acid storage battery 14 meet the conditions is obtained and judged. If the conditions are met, the current output of the lead-acid battery 14 is deemed to be unable to support normal operation of the load 20. At this time, the lead-acid battery 14 is disconnected from the power supply circuit, the lithium battery 13 and the metal fuel cell 12 are connected to the power supply circuit 30, and the metal fuel cell 12 is controlled to react.
Optionally, when the voltage of the lead-acid battery 14 is less than or equal to the second voltage, the capacity is less than or equal to the second capacity, or the utility power outage time is greater than or equal to the second time, the third switch 17 is instructed to be opened, and the first switch 15 and the second switch 16 are closed, so that the lithium battery 13 and the metal fuel cell 12 are connected to the power supply circuit.
The metal fuel cell 12 can be integrated in a cabinet, the whole floor area is small, the weight is light, fire-fighting hidden dangers caused by fuel storage are avoided, the phenomenon that the power supply time is reduced along with the change of the environmental temperature is avoided, noise is not generated during working, and waste gas pollution is avoided.
The metal fuel cell 12 is limited in its own right so that it needs to go through a reaction process for a certain time to reach the maximum output power. Therefore, during the reaction of the metal fuel cell 12 for a certain period of time, the lithium battery 13 and the metal fuel cell 12 supply power to the load 20 together to ensure the normal operation of the load 20.
After the metal fuel cell 12 reaches the maximum output power, the lithium battery 13 is charged while supplying power to the load 20, and at this time, the lithium battery 13 can play a role in stabilizing the output voltage when the output voltage of the metal fuel cell 12 is unstable. By turning off the third switch 17, the metal fuel cell 12 charges only the lithium battery 13 with better charge/discharge performance, and does not charge the lead-acid battery 14, thereby reducing the consumption of the metal fuel cell 12.
Optionally, as shown in fig. 5, when there are a plurality of lead-acid storage batteries 14 in the power switching device 10, when the voltage of the lead-acid storage battery 14 is less than or equal to the second voltage, and the capacity is less than or equal to the second capacity, or when the utility power outage time is greater than or equal to the second time, it is detected whether there is another lead-acid storage battery 14 whose voltage is greater than the second voltage or the capacity is greater than the second capacity, and if there is another lead-acid storage battery 14, the lead-acid storage battery 14 is switched to supply power to the load; if not, the third switch 17 is instructed to be opened, the first switch 15 and the second switch 16 are closed, and the lithium battery 13 and the metal fuel cell 12 are connected to the power supply circuit. When a plurality of lead-acid storage batteries 14 are available, each lead-acid storage battery 14 can supply power to the load 20 in turn, and after the output of all the lead-acid storage batteries 14 is insufficient, the power is switched to the lithium battery 13 and the metal fuel battery 12 to further prolong the working time of the load 20 when the commercial power is cut off.
Optionally, after the commercial power is recovered, the metal fuel cell 12 stops working, and after the lithium battery 13 and the lead-acid battery 14 are fully charged, the first switch 14 and the third switch 17 are closed, so that the lithium battery 13 and the lead-acid battery 14 are connected to the power supply circuit 30 to be in a floating charge state. Therefore, the situation that the voltages of the lithium battery 13 and the lead-acid storage battery 14 are unbalanced to generate circulation between the groups or one of the groups is overcharged and the other group is not fully charged is avoided.
According to the power supply switching method provided by the embodiment of the application, when the mains supply is powered off, the first switch is indicated to be closed, the third switch is indicated to be disconnected, and the lithium battery is connected into the power supply circuit to supply power to the load. When the voltage, the capacity or the commercial power outage time of the lithium battery meet the conditions, the first switch is indicated to be switched off, and the third switch is indicated to be switched on, so that the lead-acid storage battery is connected to the power supply circuit to supply power to the load. When the voltage, the capacity or the commercial power outage time of the lead-acid storage battery meet the conditions, the output of the lead-acid storage battery cannot support the normal work of the load, the third switch is indicated to be switched off, the first switch and the second switch are switched on, and the lithium battery and the metal fuel battery are connected to the power supply circuit to supply power to the load. When the power failure time is short, the normal work of the load is ensured through the lithium battery and the lead-acid storage battery, and when the power failure time is long, the load is supplied with power through the metal fuel cell which has no noise pollution and can not produce waste gas pollution, so that the problem that a standby power scheme of a communication machine room in the prior art cannot be used in areas with high user density and high environmental protection requirements is solved, and the load is supplied with power under the condition of low pollution.
