In the specific implementation process, in order to better improve the safety and the service life of the capacitor, the density can be increased by increasing the voltage of the super capacitor, for example, the super-clean organic solution is used for replacing the aqueous solution, and the voltage is widened to 5.0-5.2V, so that the problems of low density, low voltage, low electric shock and the like of the existing super capacitor are solved. Specifically, the super capacitor can be composed of super clear organic solution, mica, paper, super ceramic, high-density activated carbon, conductive carbon and carbon nanotubes.
It should be noted that, the super capacitor is a physical secondary power source with super power storage capability and capable of providing strong pulsating power, and if the super capacitor is classified into three types according to energy storage mechanism: a. an electric double layer capacitor generated by charge separation at the interface between the carbon electrode and the electrolyte; b. adopting metal oxide as an electrode, and generating oxidation-reduction reaction on the surface of the electrode and the bulk phase to generate reversible chemisorption Faraday capacitance; c. a capacitance in which a redox reaction occurs with the conductive polymer as an electrode. The double-layer super capacitor is a novel energy storage device for storing electric energy by using polarized electrolyte. The charge and discharge of the double-layer capacitor is purely a physical process, and the cycle times are high, the charge process is fast, and the double-layer capacitor is relatively suitable for being applied to electric vehicles, so that the super capacitor adopted in the embodiment of the invention is a double-layer super capacitor. The double-layer supercapacitor comprises two inactive porous plates suspended in an electrolyte, a voltage is applied to the two plates, a potential applied to the positive plates attracts negative ions in the electrolyte, and the negative plates attract positive ions, thereby forming a double-layer supercapacitor on the surfaces of the two electrodes. The super capacitor unit has high specific power, 50-100 times of that of the battery and power density up to about 10X 103W/kg, and is suitable for short-time high-power application. The super capacitor has no chemical reaction in the charge and discharge process, and has no mechanical movement such as high-speed rotation; no pollution to the environment and no noise; the energy storage device has the advantages of simple structure and small volume, and is very ideal. In addition, the composition has the following characteristics: the charging speed is high. It only takes 10 seconds to 10 minutes to fill more than 95% of its rated capacity; the cycle life is long, and the deep charge and discharge cycle can reach 1-50 ten thousand times; the energy conversion efficiency is high, and the high-current energy circulation efficiency is more than 90%; the power density is high, for example, can reach 300W/kg-50000W/kg, which is 5-10 times of that of the storage battery; the charge and discharge efficiency is high, and the internal resistance is small, so that the charge and discharge loss is also small, and the charge and discharge efficiency is high and can reach more than 90%; the temperature range is wide and can reach-40 to +70 ℃, and the reaction rate of the supercapacitor electrode material is not greatly influenced by the temperature; the detection control is convenient, and the residual electric quantity can be directly calculated through the formula E=CV2/2, so that the stored energy can be determined only by detecting the terminal voltage, and the calculation of the state of charge (SOC) is simple and accurate, so that the energy management and control are easy.
Fig. 2 is a schematic diagram of an external structure of a super capacitor energy storage system according to an embodiment of the present application. The super capacitor energy storage system comprises a charging interface for receiving the electric energy input of the power supply and a power supply interface 202 for providing electric energy to the electric automobile. The power supply is a preset solar panel power generation device, and the solar panel power generation device is not described in detail herein.
Furthermore, in the embodiment of the invention, the system further comprises an SG3525 closed-loop control driving circuit for controlling the SG3525 control chip for controlling the super-capacitor energy storage system to perform charging or discharging operation, and a driving protection circuit module for protecting the SG3525 control chip from over-current, under-voltage and over-voltage, wherein the super-capacitor energy storage system is controlled by the control chip and the driving circuit, so that the safety and the service life of the capacitor are better protected.
In addition, it should be noted that the super capacitor energy storage system of the present invention can be applied to an electric automobile, a UPS system or other low-power electric equipment, etc.
When applied to a UPS (uninterruptible power supply) system, the super capacitor energy storage system is not affected by frequent power failure, and can be fully charged in a short time. The super capacitor energy storage system becomes a good emergency power supply due to the high power density output characteristic. For example, the cooling water process of a blast furnace in a steel mill is not allowed to be interrupted, and once power is cut off, the super capacitor energy storage system can immediately provide high output power to start the diesel generator set to supply power to the blast furnace and the water pump, so that the safe production of the blast furnace is ensured.
When the super-capacitor energy storage system is applied to low-power electric equipment, the flashlight using the super-capacitor energy storage system as an energy storage element only needs 90 seconds for charging, and the cycle life can reach 50 ten thousand times. If charged and discharged once a day, it can be made longer. The super capacitor energy storage system is used as an energy storage element, so that the emergency lighting lamp has the characteristics of electricity saving, high brightness, uninterrupted property and long service life. As an energy storage system with large energy storage, high charge and discharge speed, wide working temperature range, safe and reliable work and no need of maintenance, the super capacitor gradually replaces a storage battery along with the development of super capacitor technology, the application field is continuously widened, the progress of the technology is certainly promoted, and greater economic and social benefits are obtained.
The energy density of the existing super capacitor is low, and when water is used as electrolyte solution, the decomposition voltage of the water is 1.23V; the use of an organic solution (such as acetonitrile or propylene carbonate) instead of an aqueous solution can widen the voltage window to around 2.5-2.7V. In addition, there are many factors that limit the voltage window of the supercapacitor, besides the decomposition voltage of the electrolyte, the stable voltage of the electrode material itself also limits the voltage window, such as when the activated carbon is in propylene carbonate, the oxidation of the activated carbon and the elimination of the oxygen-containing functional groups on the surface limit the upper voltage limit, while the decomposition (HER) of the trace water occluded in the activated carbon and the reduction of propylene carbonate limit the lower voltage limit. In order to obtain a comparison voltage window, consideration should be given to both the electrolyte solution and the electrode material. In the embodiment of the invention, the super capacitor can be composed of super clean organic solution, mica, paper, super ceramic, high-density activated carbon, conductive carbon and carbon nanotubes. The super-clean organic solution is used for replacing the aqueous solution, so that the defects of low density, low voltage, less electricity storage and the like of the existing super-capacitor are overcome, and the super-capacitor energy storage system utilizing the super-capacitor has a wide application prospect because the super-capacitor energy storage system has higher power density, faster charge and discharge rate and longer cycle service life. The lower energy density of the super capacitor energy storage system relative to the battery has become a constraint for the widespread use of capacitors. In addition, in the implementation process, the energy density of the capacitor mainly depends on the capacity of the electrode material itself and the voltage window of the capacitor, and the capacitance performance of the electrode material can be improved by modifying or designing new materials. For example, the specific surface area of the carbon material can be increased by an activation method, so that the electric double layer capacitance of the carbon material is increased, and a pseudo-capacitance material can be introduced to improve the energy storage performance of the material, so that the voltage window of the capacitor is increased, and the energy density can be effectively increased.
In the embodiment of the present invention, the pre-stage power transistor driving circuit module 104 may be composed of an NPN transistor and a PNP transistor. The transformer with the center tap is modified to boost again, and the direct-current voltage 380V in the front-stage power tube driving circuit module 104 is converted into direct-current voltage 700V, so that the load energy storage capacitor is charged. The super capacitor bank storage system comprises at least one independent super capacitor bank 101 and a capacitor bank 102 for placing the independent super capacitor bank 101, wherein the independent super capacitor bank 101 comprises five super capacitors, which are not limited in detail herein, and the super capacitors are connected in series. In addition, in order to be convenient for provide the electric energy for new forms of energy electric automobile, super capacitor group storehouse body electricity storage device still can include: a power supply interface 202 for providing electrical power to an electric vehicle.
