Allison Transmission Holdings, Inc. unveiled its H 3000 hybrid-propulsion system for commercial vehicles at The Work Truck Show in Indianapolis. The new product is targeted for medium- and heavy-duty trucks in distribution, refuse, utility and shuttle applications.
The fully-automatic parallel hybrid-propulsion system is based on the Allison 3000 Series transmission which is matched with hybrid system components, including a motor-generator, power electronics and lithium-ion cell battery packs. Scalable to each application, the modular lithium-ion battery packs enable an optimal amount of energy capacity to be tailored to a specific vehicle or duty cycle, allowing for greater flexibility and performance.
H 3000 is a “package” of components built around Allison’s 3000 HS (for “highway series”) transmission – a package that includes an electric motor/generator built by Remy International and 50 kilowatt (kW) Delphi lithium ion prismatic cell batteries. Each battery weighs about 150 lbs., with the other hybrid components (motor/generator and transmission, among others) adding 400 lbs.
Allison began developing hybrid technology in 1989 and, since 2003, have delivered more than 5,000 hybrid-propulsion systems for the transit bus market. The new H 3000 will now provide this technology for a much wider range of vehicles.
The H 3000 captures otherwise wasted energy during vehicle braking and uses it to assist in vehicle propulsion and powering of auxiliary equipment. The design features a torque converter fully-automatic transmission and the hybrid motor-generator. The H 3000 will also come equipped with Allison's 5th generation of electronic controls. Depending on vocation and duty cycle, the system is designed to offer fuel savings of up to 25%. Production is expected to begin later this year.
