Waukesha based Odyne Systems, LLC, a manufacturer of hybrid systems for medium- and heavy-duty work trucks, introduced its new advanced hybrid propulsion system at the Electric Utility Fleet Managers Conference (EUFMC) in Williamsburg. The new parallel plug-in hybrid system features a Remy HVH250 electric motor (earlier post)—80 hp continuous, 110 hp peak—and a choice of 14 kWh or 28 kWh lithium-ion battery packs.

Odyne was formed in 2001 for the sole purpose of developing and producing electric and hybrid electric propulsion systems for Class 5, 6, 7 and 8 vehicles. In January 2009, Odyne’s assets were acquired by the parent company of DUECO, Inc. and Utility Equipment Leasing Corporation (UELC), and relocated to a production facility in Waukesha, Wisconsin. (Earlier post.)

Odyne’s system is targeted to medium- and heavy-duty work trucks with extended stationary PTO job site functions. It is also the only plug-in hybrid system to power a gas compressor truck. The Odyne system provides launch assist and regenerative braking. Once stationary at the job site, work trucks are able to operate worksite equipment applications for up to several hours without using engine power, depending upon the application.

Time may vary depending on application

The 300V parallel plug-in hybrid system can be applied to most new chassis or applied as a retrofit, and is compatible with most chassis over 14,000-lb GVW. No drive train modifications are required; the OEM chassis components can be serviced through the chassis manufacturer’s service network. The hybrid system propulsion components are placed within chassis frame rails for ease of body installation; battery packs are situated in a variety of locations to suit application. The electric motor can drive both a PTO and hydraulic pump.

This new system delivers improved performance for medium and large work vehicles. Odyne’s unique system helps reduce operating costs through higher efficiency, 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 has developed proprietary and patent pending hybrid technology combining reliable electric power conversion, power control with advanced electric propulsion motors and modular lithium ion battery systems.

A smart way to reduce fuel consumption (and associated pollution) for most heavy vehicles and heavy machinery. Done on a massive scale it could also reduce oil import.

A special vehicle electrification fuel tax of a few cents per gallon would help to offset conversion cost to zero within less than 2 years for most heavy vehicle. We will have to be more pro-active.


Why not use those kits to convert the USPS truck and vehicle fleet.


They could do that and probably should have years ago, they may not be in the financial trouble that they are if the invested to reduce their fuel bills.
