What are the main applications of supercapacitors

The main application areas of supercapacitors :

  1. Application of supercapacitors in solar energy systems

  The utilization of solar energy source Z ultimately boils down to two aspects: solar energy utilization and sunlight utilization. Solar power generation is divided into photovoltaic power generation and photothermal power generation, among which photovoltaic power generation is the use of photovoltaic cells to directly convert solar energy into electrical energy. Photovoltaic power generation is far stronger than CSP in terms of conversion efficiency, equipment cost and development prospects. Mainly used in remote areas without electricity and urban street lights, and other independent photovoltaic power generation systems. The energy storage system formed by the battery pack can smooth out the fluctuation of electric energy caused by the fluctuation of the solar light intensity, and can also compensate the voltage dip or sudden rise in the power grid system, so its service life is short and the cost is high. The use of supercapacitor banks in solar photovoltaic power generation systems will make grid-connected power generation more feasible.

  2. Application of super capacitors in wind power generation systems

  As the fastest developing renewable energy power generation technology, wind power generation has broad application prospects. However, wind energy is a randomly changing energy source, and changes in wind speed will cause fluctuations in the output power of wind turbines, which will have an impact on the power quality of the grid.

  3. Opportunities for supercapacitors in the development of new energy vehicles

  In the field of new energy vehicles, supercapacitors can be used in conjunction with secondary batteries to achieve energy storage and battery protection. Usually supercapacitors are used in conjunction with lithium-ion batteries. The perfect combination of the two forms a power vehicle power supply with stable performance, energy saving and environmental protection, which can be used in hybrid vehicles and pure electric vehicles. Lithium-ion batteries solve the problem of charging and storing cars and providing lasting power for cars. The mission of supercapacitors is to provide high-power auxiliary power for cars to start and accelerate, and to collect and store energy when cars are braking or idling. The supercapacitor can quickly recover and store energy when the car decelerates, descends, and brakes, and safely converts the excess irregular power generated by the car into the charging energy of the battery to protect the safe and stable operation of the battery; when starting or accelerating , the battery first transfers the energy into the supercapacitor, and the supercapacitor can provide the required peak energy in a short time.
