Electric Vehicle Range-Extender – ( Solar Thermal Magazine)
Today Wrightspeed Inc. announced a new turbine generator they have named the Fulcrum. Utilizing a proprietary set of advancements, the Fulcrum is an 80kW turbine generator for electric vehicle propulsion. Wrightspeed is a Silicon Valley based manufacturer of range-extended electric vehicle powertrains.
The range extending architecture of the Fulcrum will not provide direct propulsion to the drive wheels, but be used to re-charge the battery system. This means that the Fulcrum is only used when it is needed, and can run at the cleanest and most efficient operating point. Weighing in at 250 lbs., the Fulcrum is approximately 1/10th the weight of its piston generator counterparts and it is designed to have a 10,000 hour lifetime.
While piston generators rely on catalytic converters to reduce their emissions by 10x to the meet ever-increasing California Air Resources Board standards, the Fulcrum meets emissions standards without the use of any additional equipment.
A two-stage compression process and unique recuperation design make the Fulcrum 30% more efficient than existing turbine generators, while tripling usable power. Its multi-fuel capabilities allow it to burn diesel, CNG, LNG, landfill gases, biodiesel, kerosene, propane, heating oil, and others.
“The automotive industry is in the midst of a fundamental disruption, with electric vehicles merely symbolizing the beginning of the movement. The Fulcrum, together with our range-extended EV architecture, is perfectly suited for achieving maximum efficiency in extremely high-power stop-and-go applications, such as garbage trucks,” said Ian Wright, CEO and founder of Wrightspeed. “For many of the same reasons that aviation changed from piston engines to turbines decades ago, we believe turbines will begin to replace piston engines in range-extended electric vehicle applications.”
Some of you may find it interesting that Ian Wright is also a co-founder of Tesla Motors.
