Description
Technical field
The utility model relates to a kind of storage charger that uses super capacitance cell group electric power power conversion.
Background technology
Super capacitance cell is again gold electric capacity, farad capacitor, and it carrys out energy storage by polarization electrolyte, belongs to the one of double layer capacity.Because chemical reaction does not occur the process of its energy storage, therefore this thermal energy storage process is reversible, just because of can repeated charge hundreds thousand of times of this ultracapacitor.Super capacitor generally uses high surface carbon electrode material, has adsorption area large, and static stores many features, in new-energy automobile, is widely used.Double electric layer capacitor is compared with aluminium electrolytic capacitor
internal resistance is less, therefore, can in non-loaded resistance situation, directly charge, if there is the situation of overvoltage charging, double electric layer capacitor will be opened a way and unlikely damage device, and this feature is different from the over-voltage breakdown of aluminium electrolytic capacitor.Meanwhile, double electric layer capacitor, compared with rechargeable battery, can carry out not current-limiting charge, and charging times can reach more than 10E6 time, therefore electric double layer capacitance not only has the characteristic of electric capacity, also has battery behavior simultaneously, is a kind of novel specific components between battery and electric capacity.The common capacitor of Capacity Ratio of super capacitor is much bigger.Because its capacity is very large, externally performance is identical with battery, therefore also referred to as " capacitor batteries " or title " gold battery ".Super capacitance cell is the one that Sichuan Neng Bao power supply Manufacturing Co., Ltd has dropped into capacity maximum in the double electric layer capacitor of volume production, and its general principle is to utilize the double electrical layers of high surface activity carbon porous electrode and electrolyte ingredient to obtain the capacity of super large.The energy source storing in conventional physical electric capacity is the separation on two pole plates in electric charge, between two pole plates for vacuum (relative dielectric constant is 1) or one deck dielectric material (relative dielectric constant is ε) are isolated, capacitance is: C=ε A/3.6 π d 10-6 (μ F) wherein A are polar plate area, and d is dielectric thickness.Stored energy is: E=C (Δ V) 2/2, wherein C is capacitance, Δ V is the voltage drop between pole plate. visible, obtain larger capacitance if want, store more energy, necessary area increased A or minimizing dielectric thickness d, but this extendable room is limited, causes its reserve of electricity and energy storage capacity less.Super capacitance cell adopts carbon material with high surface activity to be made into porous electrode, filling electrolyte solution between relative charcoal porous electrode simultaneously, in the time applying voltage at two ends, on relative porous electrode, assemble respectively positron-electron, and negative ions in electrolyte solution will gather respectively on the interface relative with positive/negative plate due to electric field action, thereby form two current collection layers, be equivalent to two capacitor's seriess, due to have>=2000M of absorbent charcoal material
2the superhigh specific surface area (having obtained great electrode area A) of/g, and interface distance between electrolyte and porous electrode (has obtained minimum dielectric thickness d) less than 1nm, can find out according to computing formula above, this double electric layer capacitor is more much bigger than the capacitance of traditional physics electric capacity, specific capacity can improve more than 100 times, thereby make the capacitance of Unit Weight can reach 100F/g, and the internal resistance of electric capacity can also remain on very low level.It is low that Carbon Materials also has cost, the advantages such as technology maturation.Thereby the energy storage that utilizes capacitor to carry out large electric weight is become a reality, and in the time that reality is used, can be by series connection or in parallel to improve output voltage or electric current.Ultracapacitor mostly is double electrical layers, is spatially distributed structure between its activated carbon electrodes and electrolyte, and the characteristic of ultracapacitor is described in the connection in series-parallel of available multiple capacitors.
The requirement of the quality of society to the energy and supply of electric power and security reliability is more and more higher, and traditional large mains supply mode is because the defect of itself can not meet this requirement.Can integrated distributed generating novel power grid---micro-electrical network arises at the historic moment, it can be reduced investment outlay, reduce energy consumption, improve security of system and flexibility, is following developing direction.Electric capacity, as requisite energy-storage system in micro-electrical network, is being brought into play very important effect.Micro-electrical network is made up of micro-power supply, load, energy storage and energy manager etc.In the time being incorporated into the power networks, the power fluctuation in micro-electrical network carries out balance by large electrical network, and now energy storage is in charging stand-by state.In the time that micro-electrical network is switched to lonely network operation by being incorporated into the power networks, central energy storage starts immediately, makes up power shortage.The fluctuation of loading when the lonely network operation of micro-electrical network or the fluctuation of micro-power supply can be by central energy storage or distributed energy storage balances.Wherein, the power fluctuation of micro-power supply has two kinds of balance modes, by distributed energy storage and need micro-power supply of energy storage and be connected on certain feeder line, or energy storage is directly accessed on the DC bus of this micro-power supply.The form that energy storage is had an effect in micro-electrical network has: on the feeder line that be connected on the DC bus of micro-power supply, comprises important load or on the ac bus of micro-electrical network.Wherein, first two can be described as distributed energy storage, and last one is called central energy storage.In super capacitance cell group charge and discharge process, voltage reference terminal changes greatly, conventionally must adopt DC/DC converter regulate the energy storage of super capacitance cell and release energy as interface circuit.DC/AC converter can adopt two-way DC/AC inverter, or adopts AC/DC rectifier and DC/AC inverter.Super capacitor energy storage system utilization is organized ultracapacitor more energy is stored with the form of electric field energy, in the time that energy promptly lacks or needs.The energy of storage is discharged by control unit, what accurately quick bucking-out system was required gains merit with idle again, thereby realizes the balance and stability control of electric energy.
Common super capacitance cell has three kinds of building forms: series system, parallel way and string series-parallel connection mode.The ultracapacitor assembly of series system: because the monomer operating voltage of super capacitance cell is not high, can not cover the voltage requirements scope of application operating mode, need to be by multiple monomer series-connected voltage requests that meet application operating mode, but because of the intrinsic difference between monolithic capacitor, the total voltage acting in series component can not balancedly be distributed to different capacitors, it can cause the asymmetric of voltage distribution, has the electric voltage equalization problem between monomer.Simple series connection can cause one or several monolithic capacitor overvoltage, thereby damages these capacitors, and overall performance is affected.Very large electric current can be exported or accept to super capacitance cell assembly with parallel way construction.In charging process; ensure that by serial connection charge resistance the voltage between monomer distributes, but the intrinsic charging resistor of super capacitance cell itself is a dynamic amount, has certain dispersiveness; the control circuit that adjusting resistance is changed is extremely complicated, is difficult to realize pointwise control; In discharge process, controlled discharge resistance, can obtain very high power output, but excessive for fear of discharging current, ensures the power output of license, the energy content of suitable control assembly.The super capacitance cell assembly of string series-parallel connection: in conjunction with the advantage of series and parallel connections mode, electric capacity avoids two kinds of modes not enough separately.Each capacitor is all specified the voltage of its charging process of resistance control.The more difficult control of ultracapacitor discharging current.In the time that condenser voltage exceedes nominal voltage, will cause electrolyte decomposition, capacitor can generate heat simultaneously, capacity loss, and internal resistance increase, the lost of life, in some cases, can cause capacitor performance collapse.Ultracapacitor not can be applicable in circuit that high-frequency discharges and recharges, and high-frequency fast charging and discharging can cause capacitor internal heating, capacity attenuation, and internal resistance increases, and can cause in some cases capacitor performance collapse.
