Odyne Systems is a company developing and supplying hybrid drive systems for medium and heavy-duty vehicles. The U.S. Department of Energy (DOE) selected Odyne Systems to participate in a $45.4 million project to develop and deploy plug-in hybrid systems for over 120 trucks throughout North America in 2014.
Odyne Systems claims that it has fielded more plug-in hybrid systems for large trucks throughout the United States than any other supplier.
One of Odyne's newest innovation, included in the plug-in hybrid package from Odyne Systems, is the option to power large electrical loads, equipment and tools from the trucks, instead of using dedicated generators on trucks.
If we understand the press release right, the truck can power up to 6 kW AC or up to 36 kW DC, which for now was tested at up to 18 kW. .

"The Odyne plug-in hybrid drive system for medium- and heavy-duty trucks incorporates new advanced technology capable of providing scalable pure sine exportable power of up to 6kW or greater from the hybrid battery system to power large electrical loads, equipment and tools. The Odyne export power system has been tested to 18kW and is designed for applications up to 36kW, potentially eliminating the need for vehicle mounted or towed independent electrical generators, or the need to continually idle the truck to operate engine driven generators, reducing operating costs. The Odyne system provides consistent power conversion throughout the entire range of the battery charge. The system will operate without interruption at the work site, even if battery capacity drops, since the hybrid system has the ability to recharge the battery quickly by temporarily using the chassis engine, if needed."
"The robust design of the inverter features external mounting capabilities, advanced diagnostics and improved communications capabilities for accurate control, easier servicing, power use reporting and customized programming to optimize system performance. The new system can free up space within the truck body and its unique design provides flexibility in meeting varying power requirements. Operators especially appreciate not having to maintain and fuel separate engine driven generators."
Odyne Systems is using a stock ICE engine and transmission (from Allison Transmission) combined with a Remy electric motor.
Lithium-ion batteries come from Johnson Controls.
"The unique PTO (Power Take-off) interface provides a direct connection between the hybrid system and the transmission, enabling improved fuel efficiency. When the truck is driving, the Odyne hybrid system utilizes electric launch assist and regenerative braking to save fuel. When the truck is stationary, Odyne’s hybrid system powers most equipment for the entire work day with the engine off. Sold through a worldwide distribution network, the Odyne hybrid system provides benefits for new and existing work trucks."

John Petras, Vice President of Engineering at Odyne, stated:
“Odyne closely collaborated with one of the world’s leaders in power conversion technology and manufacturing to develop the unique and proprietary advanced export power inverter that is a key component within the system. Odyne is very pleased to offer a highly scalable solution to meet the increasing demands for efficient electrification of truck and worksite loads. This technology, combined with our existing plug-in charging and smart grid capability, also takes Odyne one step closer to providing more advanced functionality, such as vehicle to grid bi-directional capabilities.”
