Sentences with phrase «as ultracapacitors»

That's the promise of energy - storage devices known as ultracapacitors, but at present, they can store only about 5 percent as much

Not exact matches

At Tesla, Elon has overseen product development and design from the beginning, including the all electric Tesla Roadster, Model S and Model X. Transitioning to a sustainable energy economy, in which electric vehicles play a pivotal role, has been one of his central interests for almost two decades, stemming from his time as a physics student working on ultracapacitors in Silicon Valley.

AFS Trinity Power in Bellevue, Washington, recently displayed a modified hybrid SUV that uses ultracapacitors alongside batteries and an internal combustion engine, and major manufacturers such as Honda and Toyota have also been experimenting with the technology.

While they still can't store as much total energy as a fuel cell or a battery, ultracapacitors — also known as electrochemical capacitors — can supply the burst of energy needed to accelerate up a hill or around another car on the highway.

The nanotubes drastically increase the surface area of the ultracapacitor electrode, allowing it to hold 20 times as much energy.

Using an onboard source of energy (such as a battery, ultracapacitor, solar panel or any combination thereof), the electrodes will send an electrical current into the plasma, causing the plasma to push against the neutral (noncharged) air surrounding the craft, theoretically generating enough force for liftoff and movement in different directions (depending on where on the craft's surface you direct the electrical current).

Seven years ago, Schindall and his colleague John Kassakian were, as Signorelli says, «starting to think... about an ultracapacitor and how to improve it.»

In the Geely - Volvo mild - hybrid installation, the ultracapacitors are expected to last the 10 - year life of the vehicles, through as many as 250,000 engine restarts.

«As we prepared to bring our new, high - performance features into the mainstream of our next - generation vehicles, it became evident that ultracapacitors would be essential to address the increasing electrification challenges the automotive industry is facing,» Geely Vice President and Chief Technology Officer Qingfeng Feng says in a statement.

The LEES ultracapacitor has the capacity to overcome this energy limitation by using vertically aligned, single - wall carbon nanotubes — one thirty - thousandth the diameter of a human hair and 100,000 times as long as they are wide.

This is why ultracapacitors, with their ability to release quick jolts of electricity and to absorb this energy just as fast, are ideal today as a complement to batteries or fuel cells in electric - drive vehicles.

If, however, ultracapacitors were paired with batteries, they could protect batteries from intense bursts of power, Bohn says, such as those needed for acceleration, thereby extending the life of the batteries.

-LSB-...] If ultracapacitors were paired with batteries, they could protect batteries from intense bursts of power, Bohn says, such as those needed for acceleration, thereby extending the life of the batteries.

Ultracapacitors could also ensure that the car can accelerate just as well at the end of its life as at the beginning.»

Unlike a conventional trolley bus that has to continually touch an overhead power line, Sinautec's ultracapacitor buses take big sips of electricity every two or three miles at designated charging stations, which double as bus stops.
