UQM Technologies Introduces 200 kW System for Heavy-Duty Vehicle and Generator Applications

UQM Technologies, Inc. has released a new 200 kW motor/generator system for use in electric propulsion systems for heavy-duty vehicles and generator applications.

The new system extends the peak power available in its 405 mm diameter frame size to 200 kW, and has a continuous power rating of 115 kW. Peak torque is 900 N·m (664 lb-ft), and continuous torque is 450 N·m (332 lb-ft).

We are pleased to add the PowerPhase 200 system to our lineup of electric propulsion systems for heavy-duty vehicle applications. The higher peak output rating of this system will improve the operating characteristics of larger vehicles, most notably for grade climbing and acceleration.

—Jon Lutz, UQM Technologies’ Vice President of Technology

UQM propulsion systems and generators are available in a variety of power levels in either a 280 mm diameter frame size or a larger 405 mm diameter frame size.

Yes, batteries have been available for hybrid electric vehicles for over ten years, perhaps a hundred. Regeneration is just as important in lorries as it is in a Prius, but the main advantage is that a small more efficient engine can be used. General Electric has tested and will be building series hybrid locomotives. They may save themselves some battery costs by using modern flywheels for peak power demands.

These new locomotives can also save fuel by using cheap intermittant third rail electrification because continuous power is not needed and peak power is not needed because of modern electronics. Flywheel locomotives and electro-diesels demostrated such an operation in London and to the Coast over fifty years ago. The breaks in electrification can be just a few feet for level crossings or turnouts or can be hundreds of miles long and low profile ground mounted third rail systems can be used.

One or more lanes of motorways and major roads can also be equipped with a similarly disconnected electrification systems at a small fraction of the total cost of the construction of such roads. Several systems have already been invented but new and much cheaper ones can be used for traction battery equipped vehicles. As traveling in automobiles is already dangerous and has been made more dangerous with cell phone use, there is no need to go to great expense to provide ultra safe expensive electrification systems. ..HG..
