First Compact, Inline, Triple-Function, Plug-In Vehicle Drivetrain Launched by

Published:

PALO ALTO, CA -- (Marketwire) -- 11/19/12 -- Efficient Drivetrains, Inc. (EDI), a global leader in advanced, high-efficiency PHEV and CVT solutions, today announced it has completed the development and initial functional testing of the world's first Parallel-Series-Electric powertrain system that is less complex, more efficient, less costly, and lighter than the competition.

The new EDI drivetrain, which incorporates components from GM, A123, and UQM, was integrated into a light-duty GM pickup truck to create the demonstrator vehicle. The drivetrain, which is scalable to light, medium, and heavy-duty applications, utilizes no power split gears and features special clutching systems.

EDI designed the drivetrain in an inline form factor to make it highly adaptable to existing front engine, rear wheel drive vehicles, reducing the need to make significant changes to existing vehicle designs.

"For manufacturers and consumers alike, this is the most adaptable automatic vehicle drivetrain in the world, and the vehicle has performed extremely well in initial testing," said Joerg Ferchau, Co-founder and CEO of EDI. "It's scalable, less complex, and lighter than the competition. When conditions warrant, it can operate as either a pure EV for trips around the neighborhood, or as a Series Hybrid, optimum for stop-and-go city traffic conditions, or as an efficient Parallel Hybrid that is ideal for the highway. It also features an EV+ Mode for hill climbing and added acceleration."

EDI has created a new, second-generation PHEV concept. It has higher overall efficiency than its predecessors, featuring a larger battery pack and a motor system that incorporates fewer parts and smaller, more efficient gasoline/bio-fuel engines. To further increase efficiency, an EDI Turbo-generator system can make it the most efficient powertrain in the world, for a given power.

"We've taken a lot of complexity out of the PHEV side of the equation," said Professor Andy Frank, Co-founder and CTO of EDI. "And because it has an Inline form factor it is highly adaptable to existing front engine, rear wheel drive vehicles, thus reducing the need for significant existing vehicle design changes."

The drivetrain has been in development since early 2011. The concept leverages EDI IP in the area of hybrid drivetrain design and controls, and has also generated new IP, which will be covered in several new patent applications. Vehicle product testing and refinement will continue over the next quarter.

"This is the simplest, most elegant, most efficient design possible to capture the three basic modes of vehicle operation," said Ken Baker, CEO of TechBroker LLC, EDI Advisory Board member, and GM EV-1 creator. "This goes a long way to proving EDI and their technology as a viable option for industry, as well as commercial partners."

EDI will soon announce its first commercial contract to implement the system into a full size, heavy-duty bus project in China, and is also in discussions with multiple OEM truck manufacturers and upfitters at the current time.
