Super capacitor made a technological breakthrough

"Supercapacitor is a new type of physical energy storage device between traditional capacitor and battery. It has the advantages of large capacity, high power density, fast charge and discharge, long cycle life and so on. Changsha New Energy Co., Ltd., chairman of Xie? U An interview with reporters, said that with the battery, super capacitor charging and discharging process is basically a physical process, so stable performance, green. In the new energy vehicles, wind power generation, construction machinery , rail transit and national defense and other fields have a wide range of applications.

Green energy in the field of energy storage

With the global warming and lack of resources, various countries and regions all over the world are developing new green energy sources. The materials used in the production of supercapacitors are generally green and are competing for more and more countries and enterprises Research and production, domestic manufacturers engaged in large-capacity super capacitor R & D has reached more than 50.

In fact, the super capacitor has rapidly expanded in global demand since its launch and has become a new industry highlight in the field of chemical power supply. This breakthrough not only fundamentally changed the position of electric vehicles in transportation , but also improved the possibility of intermittent use of energy such as wind and solar energy to reduce the dependence on fossil fuels while meeting people's demand for energy.

The use of supercapacitors determines its strategic value. The deep adjustment of China's economic structure and the introduction of industrial support policies will greatly facilitate the development of the upstream and downstream industrial chains of the strategic products. "At present, the supercapacitor industry is still in the early stage of rapid development, and its future development space is still huge. The major areas for future supercapacitors will be concentrated in the fields of transportation, smart grids and construction machinery. Due to their high technical barriers, High excess return. "Xie? U on the future of the super capacitor industry is full of confidence.

"In recent years, as the new energy industry, especially the rapid development of new energy automotive industry, as the core power storage equipment supercapacitor has entered a phase of rapid development.Capacitor is the most advanced energy storage equipment." Some expert analysis That the latest technology is expected to make the device can quickly fully charged, these devices can be widely used in everything from mobile electronics to industrial equipment.

Or will become the main driving force of electric vehicles

"Battery technology, there are many problems to be solved; and the capacitor is not the same with the battery, charging fast, in the direction of the development of electric vehicles, there should be a variety of similar ultra-capacitor technology line." Some experts believe that.

Supercapacitors are emerging in new technologies that require more efficient and reliable power supplies, and the emergence of the supercapacitor bus has effectively solved this challenge. Supercapacitors have become an advanced energy storage device that can improve the defects of traditional trams and exert their advantages of zero emission, energy saving, low cost and low noise. Supercapacitor Bus is a new type of energy-saving tram with supercapacitor as its power source. The vehicle keeps the advantages of trolleybus without any emission.

"Although EVs are a key component of the global automotive industry and supercapacitors are the key components, the research on this new technology is still in the exploratory stage in the world, and the key performance indicators need to be further improved. Our country is one step ahead in the application of supercapacitor bus trains. "Xie? U Ann told reporters that at present the price of supercapacitor bus is higher than that of ordinary buses. With the gradual expansion of the application range, the production cost is decreasing day by day, After the industrialized production stage, the price can also drop substantially.

At present, the Super Capacitor produced by Changsha Guorong New Energy Co., Ltd., as a driving force 12-meter supercapacitive electric bus of Zhongshang Automobile Company, has entered the subsidy list of recommended models for the demonstration and promotion of national new energy vehicles. The subsidized bus users only need to pay Buying four fuel vehicles abroad, but in the eight-year operation period of more than 1.5 million yuan per vehicle energy saving additional benefits, while more than 30 tons of direct emissions. Super capacitor electric bus easy to operate simple, strong power superior to the fuel truck, no deflagration risk, the service life of up to 10 years. Relative to the battery charging time of 6 to 8 hours, the super capacitor only 3 to 5 minutes to achieve full charge, without the need to build large charging stations, greatly reducing the power investment.

As technology continues to improve and become more mature, green new energy cars and new energy trucks will also be a large number of various types of large quantities of electric vehicles bound to be carried in China and the rest of the world hope that the future, ultra-capacitors will Will have more broad and lofty market prospects.

Xie? U An analysis that the bus compared to the car, the urgency of the city stronger, he hopes to support the infrastructure when the conditions can be better to promote pure electric cars.

However, according to preliminary calculations, if the super capacitor is used as the electric part of the hybrid electric car, the annual energy saving will reach 30% ~ 40%. At present, the best battery-type hybrid electric car is only measured in energy saving 8% ~ 12%.

Previous energy storage devices were converted from electrical energy into chemical energy, and then by the chemical energy into electrical energy, two changes of energy loss, supercapacitors direct charge, and then direct discharge, the energy form has not changed, the energy loss is very small, charge Discharge efficiency up to 98%. Super capacitor electric bus to environmental protection, energy saving, low cost advantages, has become the best solution for the modernization of public transport.
