Flywheel energy storage - new power of energy vehicle

China energy storage net news: recently, in wuhan university of technology institute of electrical and mechanical engineering professor Hu Ye hair team to cast new energy vehicle technology - "for new energy automobile generators and high density flywheel energy storage system", obtain 500 million yuan of investment in science and technology achievements transformation.Learned, invented the technology for the world, such as to achieve mass production on the market, the size of the market is expected to create 5 billion yuan.

The flywheel energy storage system refers to the use of motor drive the high-speed rotating flywheel, storing electrical energy into kinetic energy, in need of a flywheel is needed to drive the generator with power generation way of energy storage.With a built-in motor in flywheel energy storage device, it is both motor and generator.When charging, it as a motor to the flywheel speed;When the discharge, it as a generator external power supply.

In the 1990 s, the flywheelThe batteryNew concept is put forward, it breakthrough the limitations of the chemical battery and use physical method to achieve energy storage, electric energy and mechanical energy conversion, because it is not cause pollution.The flywheelEnergy storage batteryOriginally just want to apply it on the electric car, but limited to the technical level, and didn't get development.Hu Ye hair is introduced, some developed countries are currently research on high temperature superconducting magnetic levitation bearing flywheel energy storage system.The flywheel energy storage research mainly focus on research and development to improve the energy density of composite technology and superconducting maglev technology.The superconducting maglev is the main way to reduce losses, and composite materials can increase the energy storage density, and reduce the system volume and weight.

In recent years, the domestic market began to flywheel energy storage.The United States, Germany, Japan and other developed countries for the development and application of flywheel energy storage is more, but because of the volume and quality of "smaller" technical problems, temporarily can only be used in plane, train, large machinery and equipment.

"If can realize to apply this technology in the field of new energy vehicles, using relatively small engine to provide power, can achieve the goal of energy conservation and emission reduction."Hu Ye said, on the market at present the electric car battery charging time for several hours, not only body heavy use not convenient, life is not strong.After several years research, the team has been in the laboratory to develop relevant "miniaturization" technique, and obtain a number of patents, filled the domestic blank.If successful transformation technology, the electric car can realize not only lighter in weight, also can reduce the charging time of the electric vehicles to more than 10 minutes, "the development of new energy automotive industry of our country make a huge change."

"Last year, had a job at the American ford company chinese-american entrepreneurs in the knowledge of the technology of the team, then get in touch with us, this year under the impetus of the relevant departments, finally decided to invest in wuhan for achievements."Hu Ye said, pre-project goes well, the fastest in two years is expected to implement new technology in the application of new energy vehicles.
