s. The company has developed PHEV technology that actively combines batteries with ultracapacitors. The company asserts that the combination of high-power ultracapacitors, which prefer to discharge and recharge quickly, and high-energy lithium-ion batteries, which prefer to discharge and recharge slowly, makes for a system with both long-life and high energy-density storage.

Prototype

AFS Trinity claims that this "Extreme Hybrid" technology makes it possible for plug-in hybrid electric vehicles to achieve the equivalent of 150 miles per US gallon (63.8 km/L), travel 40 miles (64.4 km) per charge in all-electric mode and use gasoline for additional range (limited by gasoline tank size) in hybrid mode. The company also reports that its prototype "XH-150S" modified Saturn Vue

 SUVs demonstrated 11.6 second 0-60 performance in electric-only mode and 6.9 second 0-60 performance in full hybrid mode, which would be comparable to a Porsche Cayenne.

AFS Trinity's Extreme Hybrid prototypes have been test-driven by journalists from The New York Times, The Washington Post, ABC World News, CBS Evening News, CNN, and Salon.

History

AFS Trinity was formed on December 5, 2000, through the combination of two predecessor companies, American Flywheel Systems, Inc. (AFS), incorporated in 1991, and Trinity Flywheel Power (Trinity) which was incorporated in 1993. Since 1991, AFS Trinity has conducted programs with private and government organizations including DARPA, NASA

On January 26, 2010, AFS Trinity demonstrated its prototypes for Delaware officials including Governor Jack Markell, suggesting that Delaware's idled factories and workforce could potentially mass produce the vehicle.

Technology

The powertrain using two forms of energy storage is disclosed in US patent application 11/519,350.

The application describes a family of architectures where a battery is used in conjunction with a second energy storage device which may be an ultracapacitor, a flywheel
Flywheel
A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have a significant moment of inertia, and thus resist changes in rotational speed. The amount of energy stored in a flywheel is proportional to the square of its rotational speed...

, or a second battery. The purpose of the second energy storage device is to protect the battery from high current during high power operation.
