Energy-storage module 400 charges；The transformation of electrical energy module 200 is used to switch the charging object of the metal-air battery module 100；
Wherein, the metal-air battery module 100, first energy-storage module 300 and second energy-storage module 400 can be made
For out-put supply.
Specifically, including a metal-air battery module 100 and two energy-storage modules in the power-supply system 10, this three
Person can be used as the out-put supply of the power-supply system 10.Wherein, specifically by a metal-air battery module 100 and two
Which module in energy-storage module is as out-put supply, by the transformation of electrical energy module 200 in the power-supply system 10 according to reality
Situation switching is realized.And the charging object of metal-air battery module 100 should difference according to the actual situation, can be first
Energy-storage module 300 or the second energy-storage module 400.
There are a variety of situations for the power supply output of the power-supply system 10: the first, when original state, when the first energy-storage module
When 300 electricity abundance, metal-air battery module 100 and the second energy-storage module 400 are without power output, electric energy at this time
Conversion module 200 switches to the first energy-storage module 300 and carries out power output.Second, when 300 not enough power supply of the first energy-storage module
When, transformation of electrical energy module 200, which cuts off the power output of the first energy-storage module 300 and switches to the second energy-storage module 400, carries out electricity
It can export, while control metal-air battery module 100 and charging to the first energy-storage module 300；When the first energy-storage module 300
When charging complete, transformation of electrical energy module 200 switches to the independent progress power output of the second energy-storage module 400, at this point, metal-air
Battery module 100 and the first energy-storage module 300 are without power output.The third, when 400 electricity of the second energy-storage module not
When sufficient, transformation of electrical energy module 200 cuts off the power output of the second energy-storage module 400 and switches to the progress of the first energy-storage module 300
Power output, while controlling metal-air battery module 100 and charging to the second energy-storage module 400；When the second energy-storage module
When 400 charging complete, transformation of electrical energy module 200 switches to the independent progress power output of the first energy-storage module 300, at this point, metal
Air cell module 100 and the second energy-storage module 400 are without power output.
It should be noted that above-mentioned three kinds of states are only three kinds of schemes provided in an embodiment of the present invention, gone back in actual conditions
It is likely to occur other situations, it should be adjusted according to the actual situation, the embodiment of the present invention does not limit specifically.
In above-mentioned three kinds of states, when metal-air battery module 100 is without power output, internal electrolyte
Isolated state should be in metal-air battery heap；When metal-air battery module 100 to the first energy-storage module 300 or
When second energy-storage module 400 is rechargeable, internal electrolyte should be in the state contacted with metal-air battery heap.
For example, metal-air battery module 100 may include electrolytic bath and metal-air battery heap, wherein electricity
Solution liquid bath is for accommodating electrolyte.By piping connection, being provided on pipeline can be with for above-mentioned electrolytic bath and metal-air heap
The valve whether control piper is connected to.When metal-air battery module 100 is without power output, valve is closed, at electrolyte
It in electrolytic bath, is not contacted with metal-air battery heap, metal-air battery heap cannot export electric energy；Work as metal-air battery
When module 100 charges to the first energy-storage module 300 or the second energy-storage module 400, valve is opened, and electrolyte is along pipeline from electricity
It solves in liquid bath and flows into metal-air battery heap, metal-air battery heap can export electric energy；When metal-air battery module 100
After 400 charging complete of the first energy-storage module 300 or the second energy-storage module, the electrolyte in metal-air battery heap is discharged,
It is then shut off valve, metal-air battery heap cannot export electric energy.Wherein, after the electrolyte discharge in metal-air battery heap,
It can use clear water to clean metal-air battery heap.
It should be noted that the mode that can above-mentioned control metal-air battery module 100 export electric energy is only the present invention
A kind of scheme that embodiment provides, the embodiment of the present invention do not limit specifically, all that control metal-air battery may be implemented
The mode that can module 100 export electric energy belongs to the scope of protection of the invention, it should be adjusted according to the actual situation.Metal
Air cell heap can make cathode by the stronger metal of movable metallic, such as: aluminium, zinc etc..
The control of power output is either pass through the automations controls such as chip internal in system in above-mentioned power-supply system 10
System, is also possible to artificially manually control.For example, user when in use, has found the energy-storage module electricity of present discharge not
Foot can control transformation of electrical energy module 200 and switch out-put supply by modes such as button, a handles；Alternatively, transformation of electrical energy
Chip in module 200 detects the energy-storage module not enough power supply of present discharge, then switches out-put supply.
In metal-air battery module 100, the first energy-storage module 300 and the second energy-storage module 400, the first energy storage mould
Block 300 or the second energy-storage module 400 break down, and metal-air battery module 100 can assist the storage of another normal work
Energy module independently carries out electrical energy transportation.When the power-supply system 10, which is in, needs a large amount of electric energy in the short time, using energy-storage module
Power supply；When the power-supply system 10, which is in, powers for a long time, using metal air cell.When metal-air battery module
100, in the first energy-storage module 300 and the second energy-storage module 400, the first energy-storage module 300 and the second energy-storage module 400 are
It breaks down, metal-air battery module 100 can also be independently powered.
