Application and Present Situation of Flywheel Battery

Due to technical and material price restrictions, the price of flywheel batteries is relatively high, and its advantages can not be reflected in small occasions. However, in the following cases where large energy storage devices are required, the use of chemical batteries is also very expensive, and flywheel batteries have been gradually applied.

Space includesspecials, spacecraft, and space stations. A single charge of a flywheel battery can provide twice the power of a weight chemical battery, and the same load is used 3 to 10 times as long as a chemical battery. At the same time, because its speed is measurable and controllable, it is possible to check the amount of electricity at any time. NASA has installed 48 flywheel batteries on the space station, which together can provide more than 150 KW of electricity. It is estimated that about $2 million can be saved compared to chemical batteries.

Transportation includes trains and cars. This type of vehicle uses a mixture of internal combustion engines and motors. The flywheel battery charges quickly and discharges completely. It is very suitable for use in hybrid energy-driven vehicles. When the vehicle is in normal operation and braking, it charges the flywheel battery. When the flywheel battery accelerates or climbs, it provides power to the vehicle to ensure that the vehicle runs at a smooth and optimal speed, which can reduce fuel consumption., Air and noise pollution, engine maintenance, extended engine life. TEXAS University in the United States has developed a flywheel battery for automobiles. The battery can provide 150 KW of energy when required by the vehicle and can accelerate the loading of vehicles to 100 Km/h.

3, the uninterrupted power supply flywheel battery can provide a high reliable stable power supply, can provide a few seconds to a few minutes of electricity, this time enough to ensure the factory to switch power. GmbH of Germany manufactured a UPS using flywheel batteries that can provide or absorb 5MW of electricity within 5s.

As an emerging energy storage method, Flywheel batteries have the unmatched advantages of traditional chemical batteries that have been widely recognized by people. It is very consistent with the development direction of energy storage technology in the future. In addition to the application fields described above, Flywheel batteries are also developing in the direction of miniaturization and low cost. Most likely, cell phone batteries. Predictably, with advances in technology and materials science, Flywheel batteries will play an important role in all walks of life in the future.

application

In the final round of the 2010 Le Mans series, the Porsche 911 GT3 hybrid car officially used this technology for the first time(the car's performance was ranked in the middle of the game).

The 911 GT3 is Porsche's first hybrid car. It is the predecessor of the 918 Spyder hybrid car, which will be launched in 2012. Detelefu·fengpulateng, chief executive of Porsche North America, said the flywheel technology used in the two models represented the future of Porsche.

"The car will define the direction of Porsche for the next 60 years," Fengpulateng said.

Porsche 918 Spyder Hybrid

Flywheel technology uses two electric motors in the front wheel to supplement the engine's power(in this model, the rear engine has 480 horsepower). Flywheel technology converts the kinetic energy collected by braking into electrical energy and stores the energy in a flywheel. During the acceleration process, this energy will be transferred to the front wheel, which carries the internal combustion engine. This process will significantly reduce fuel consumption and increase the range of travel; In racing, a major advantage of flywheel technology is that the car refuels less often, winning valuable time on the court.

Making cars more efficient without sacrificing speed and agility is an exciting step forward -- the Porsche 918 Spyder hybrid is not a cringe car, it has a full wheel drive of 500 horsepower. It takes only 3.2 seconds to increase the speed from 0 to 62 miles per second. Porsche said 900 prospective buyers had signed up for the car.
