In 2011, Odyne introduced an innovative plug-in hybrid power system which interfaces with the Allison family of commercial vehicle transmissions. In July of 2012, Allison Transmission invested in a non-controlling equity stake in Odyne Systems, LLC. The initial relationship related to hybrid systems for the 2000 Series Allison transmission, which has now been expanded to include the 3000 and 4000 Series Allison transmissions at the completion of design reviews for those products.
The Odyne hybrid power system combines reliable electric power conversion, power control and energy storage technology. Energy is captured using Remy advanced electric propulsion motors, Johnson Controls lithium-ion battery technology, and other components. The PTO interface provides a direct connection between the hybrid system and the transmission, enabling improved driving fuel efficiency.
When the truck is stationary, Odyne’s hybrid system and ePTO can power most equipment for the entire work day with the engine off. The Odyne plug-in hybrid drive system reduces fleet operating and maintenance costs, and depending on duty cycle, enables large trucks to obtain fuel economy improvements of up to 50% compared to traditional diesel or gasoline engines. Odyne continues to be the only plug-in hybrid system on a medium- or heavy-duty truck to deliver greater fuel efficiency both while driving and at the work site.
In 2013, Odyne Systems was selected to participate in a $45.4-million Department of Energy (DOE) award to develop and deploy plug-in hybrid systems for more than 120 trucks for companies and governmental entities throughout North America.
Allison Transmission is the largest manufacturer of fully automatic transmissions for medium- and heavy-duty commercial vehicles, and is a leader in hybrid-propulsion systems for city buses. Allison transmissions are used in a variety of applications including refuse, construction, fire, distribution, bus, motorhomes, defense and energy.
