Further, the 28 independent super capacitor sets 101 are connected in series through a power line.
In the specific implementation process, in order to better improve the safety and the service life of the capacitor, the voltage of the super capacitor can be increased to increase the density, for example, an ultra-clear organic solution is used for replacing an aqueous solution, and the voltage is widened to 5.0-5.2V, so that the problems of low density, low voltage and few electric shock of the conventional super capacitor are solved. Specifically, 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 capacitor is a physical secondary power source with super storage capacity and capable of providing strong pulse power, the super capacitor is mainly divided into three types according to an energy storage mechanism, namely a double-electric-layer capacitor generated by charge separation on a carbon electrode and an electrolyte interface, b, a metal oxide is used as an electrode, an oxidation reduction reaction is carried out on the surface and a bulk phase of the electrode to generate a Faraday capacitance of reversible chemical adsorption, c, a capacitor generated by an oxidation reduction reaction is used as an electrode, an electric double-electric-layer super capacitor is a novel energy storage device for storing electric energy by means of polarized electrolyte, the charge and discharge of the double-electric-layer capacitor are purely in a physical process, the cycle times are high, the charging process is fast and the super capacitor is suitable for being applied to an electric vehicle, so the super capacitor adopted in the embodiment of the invention is the double-electric-layer super capacitor, the double-electric-layer super capacitor comprises two non-active porous plates suspended in an electrolyte, voltage is loaded on the two plates, negative ions in the electrolyte, the super capacitor is added to the super capacitor, the super capacitor is capable of attracting the negative ions in the electrolyte, the super capacitor is suitable for absorbing the super capacitor, the super capacitor can be applied to the super capacitor, the super capacitor can be applied to the super capacitor, the super capacitor can be applied to absorb the super capacitor, the super capacitor can be applied to the super capacitor, the.

The super capacitor energy storage system comprises a charging interface for receiving electric energy input of a power supply and a power supply interface 202 for providing electric energy for the electric automobile. Wherein, power supply is predetermined solar panel power generation facility, solar panel power generation facility is no longer elaborated herein.
Furthermore, in the embodiment of the present invention, the super capacitor energy storage system may further include an SG3525 control chip for controlling the super capacitor energy storage system to perform charging or discharging operations, an SG3525 closed-loop control driving circuit for protecting the SG3525 control chip, and a driving protection circuit module for protecting the circuit from overcurrent, undervoltage, and overvoltage, and 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, the super capacitor energy storage system of the present invention can be applied to an electric vehicle, a UPS system, other low power electric equipment, and the like.
When the super capacitor energy storage system is applied to a UPS (uninterrupted power supply) system, the super capacitor energy storage system cannot be influenced 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 of the super capacitor energy storage system. For example, the water cooling process of a blast furnace in a steel plant is not allowed to be interrupted, once power is cut off, the super-capacitor energy storage system can immediately provide high output power to start the diesel generator set so as to supply power to the blast furnace and the water pump, and the safe production of the blast furnace is ensured.
When the super-capacitor energy storage system is applied to low-power electric equipment, the super-capacitor energy storage system is used as an energy storage element of the flashlight, the charging time is only 90s, and the cycle life can reach 50 ten thousand times. If the charging and discharging are carried out once a day, the charging and discharging time can be prolonged. The super-capacitor energy storage system is used as an energy storage element, so that the emergency illuminating lamp has the characteristics of electricity saving, high brightness, uninterruptibility and long service life. As an energy storage system with large energy storage, high charging and discharging 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 the super capacitor technology, the application field is continuously widened, the technical progress is certainly promoted, and greater economic and social benefits are obtained.
The energy density of the conventional super capacitor is low, and when water is used as an electrolyte solution, the decomposition voltage of the water is 1.23V; the voltage window can be widened to around 2.5-2.7V using organic solutions (such as acetonitrile or propylene carbonate) instead of aqueous solutions. In addition, the voltage window of the supercapacitor is limited by a plurality of factors, besides the decomposition voltage of an electrolyte, the stable voltage of an electrode material per se also restricts the voltage window, for example, when the activated carbon is in propylene carbonate, the upper voltage limit is limited by the oxidation of the activated carbon and the elimination of oxygen-containing functional groups on the surface, and the lower voltage limit is limited by the decomposition (HER) of trace water occluded in the activated carbon and the reduction of the propylene carbonate. To obtain a comparative 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. By using the ultra-clear organic solution to replace the aqueous solution, the defects of low density, low voltage and less electricity storage of the conventional super capacitor are overcome, so that the super capacitor energy storage system using the super capacitor has high power density, high charge-discharge rate and long cycle service life, and therefore, the super capacitor energy storage system has wide application prospect. Compared with a battery, the energy density of the super capacitor energy storage system is low, which restricts the wide use of the capacitor. In addition, in the specific implementation process, the energy density of the capacitor mainly depends on the capacity of the electrode material and the voltage window of the capacitor, and the capacitance performance of the electrode material can be improved by modifying or designing a new material. 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 the energy storage performance of the material can be improved by introducing a pseudo-capacitance material, so that the voltage window of the capacitor is improved, 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 type transistor and a PNP type transistor. The voltage is increased again by modifying the transformer with the center tap, and the direct-current voltage 380V in the front-stage power tube driving circuit module 104 is converted into the direct-current voltage 700V, so that the load energy storage capacitor is charged. The super capacitor bank bin body electricity storage system comprises at least one group of independent super capacitor bank 101 and a capacitor bin body 102 used for placing the independent super capacitor bank 101, wherein the independent super capacitor bank 101 comprises five super capacitors, which are not specifically limited herein, and the super capacitors are connected in series.
