Army Working on Hybrid Humvees

http://dodenergy.blogspot.com/2008/09/hybrid-humvee.html

Picture above is an XM1124 Hybrid-Electric Humvee on an M1113 Humvee chassis powered by a diesel-series hybrid featuring an all-electric drive train. The Army's been working on again/off again on getting better mileage out of its tactical vehicles. Do a search and you'll see it has terminated as many efforts as it's started. Well, that's research and engineering for you. The performance requirements for a Humvee are a bit different than for a Prius. Not more stringent, necessarily, but definitely different.  Think: survivability.  Here you'll find a smart video on Engineering TV explaining how the hybrid power sytems work on this beast. Two details jumped out from this video for me:
  • It can do 6 miles silent patrol mode before the engine has to kick in
  • 15 Kw generator provides silent power for sensors/comm gear
Acronym translation for the org that's working on this - RDECOM/TARDEC: 
  • RDECOM = Research, Development and Engineering Command
  • TARDEC = Tank, Automotive Research, Development and Engineering Center
TARDEC has a conference coming up shortly on tactical hybrids and other approaches to squeezing more miles out a gallon of fuel. You could say their job is to turn GPM vehicles into MPG vehicles.  Keep an eye on here for info on the Fuel Efficient Ground Vehicle Demonstrator and the upcoming industry day on 30 Sep 08 in Michigan.
 
Enthusiastic Prius geeks know about a little something called "stealth mode," in which the driver applies a light touch or "feathering" in order to keep the gas engine off and the electric motor powering the car. But the U.S. Army's hybrid Humvee has what Prius owners really want: a switch for running on "stealth mode," which gives the driver some 10 kilometers of TOTALLY SILENT OPERATION. The Army has a non-moving version of "stealth mode," which they call "Silent Watch" -- the massive electric motor battery is used to silently power surveillance and communications equipment.

California Gov. Arnold Schwarzenegger and U.S. Army Tank Automotive Research, Development and Engineering Center National Automotive Center Director Paul Skalny discuss an XM-1124 Hybrid-Electric Humvee at the Society of Automotive Engineers 2009 World Congress in Michigan April 20.

The Hybrid-Electric Humvee has a diesel engine and electric motor generator which are combined to create a series hybrid that uses two traction motors to drive the front and rear axles.

The system has the capability to allow the user six hours of silent watch and up to six miles of silent mobility using its battery system. Additionally, this vehicle can export up to 30 kW of power to external sources.

The theme of this year's Society of Automotive Engineers 2009 World Congress in Michigan this week is "Racing to Green Mobility," and U.S. Army Tank Automotive Research, Development and Engineering Center's display features alternative energy sources it has been developing.

Leading presidential candidate Barack Obama earmarked $1 million for research on turning Hummers into hybrids. The earmark money will go to the Illinois Institute of Technology (Obama just happens to be the senator from Illinois) for the development of a cost-effective hybrid conversion kit. These kits could turn the army's gas guzzling Humvees into fuel efficient hybrids and would be a real endorsement for hybrid conversion in general.

The military is very interested in electric power trains because they offer
many advantages on the battlefield like shorter supply lines and quiet operation. Obama has also been a very big supporter of hybrids even calling for every single government car to be a plug-in hybrid when it becomes possible. While, technically, GM can hybridize their Hummers and celebrities like Paris Hilton are willing to voice support for such a plan, GM probably won't make a hybrid Hummer.
