Hybrid Humvee coming up over the horizon

Trying to power the iconic fuel-guzzling High Mobility Multipurpose Wheeled Vehicle (HMMWV aka Humvee) with a battery, may seem like trying to put out a fire with a garden hose. But a lithium-ion battery system can deliver a lot of power from a battery quickly, giving a truck like the Humvee the thrust it requires.
EnerDel, a subsidiary of Ener1, will collaborate with the U.S. Army's Tank Automotive Research, Development, and Engineering Center (TARDEC) on four possible power systems that could be implemented in the XM1124 version of the Humvee.
The company, which specializes in battery cell chemistry as well as the electronics and battery system designs, said it already has two viable options. EnerDel has developed a lithium-tatinate system in conjunction with Argonne National Laboratory that could accommodate the acceleration and hard braking required for such a powerful vehicle like the Humvee. It also has a lithium-manganese system that would give a vehicle extra-long range and allow electronics to be run off the battery for extended periods of time before needing to be recharged.
As part of the 18-month contract, EnerDel will also be involved in testing the systems under "extreme performance simulations." In addition to putting the test vehicles through the usual Humvee paces of wading through water and mountain climbing, there will also be an endurance test.
That will include seeing how a hybrid Humvee fares as a power plant for a field hospital or temporary military post. The requirement makes perfect sense given the ease with which a Humvee can be transported to hard-to-reach areas. One of its key features has always been that it could be dropped in to virtually any terrain by parachute.

The hybrid version of the Humvee will have a powered-down "silent watch" mode that will allow it to run with its diesel generator off, reducing not only its noise, but also its thermal signature to avoid detection.
As always with major military project announcements, the company involved was quick to point out the down-the-road commercial application of its technology.
"In keeping with a long tradition, we also expect that innovations perfected here will have important benefits for the commercial markets," EnerDel President Rick Stanley said in a a statement.
There has already been interest in Raser Technologies' H3E, a plug-in hybrid version of a Hummer-branded SUV called the H3. While not truly a Hummer (the civilian version of the Humvee), the "Hummer-light" descendant has garnered the interest of even the most discerning Hummer enthusiasts.
So if EnerDel's batteries might be good enough to power a Hummvee, why haven't commercial automakers been knocking? They have actually. The company has signed research partnerships of varying commitment levels with Think Global, Fisker Automotive, Volvo, and Nissan. Its parent company, Ener1, is also working with U.S. utilities to develop smart grid storage units.

I'm a little confused here. If the Humvee is made by Hummer, which is a consumer based auto manufacturer recently purchased by Sichuan Tengzhong Heavy Industrial Machinery from General Motors, why are you asking how come commercial automakers aren't knocking? General Motors is a consumer based auto manufacturer!
No wonder the world - and in particular North America - is in such a bad way. Other than personal vanity, there is absolutely no legitimate requirement for a Hummer on the public roads. Arguably they actually make the roads more dangerous for those of us driving smaller more efficient vehicles.
If someone wants to buy one of these replacements for inadequate genitalia, tax the h*ll out of it...
and don't let the manufacturers to try to market it as a clean or green alternative
And how is producing a PHEV drivetrain and putting it in a large vehicle greenwashing? It certainly looks like their acheiving remarkable efficiencies that exceed even Toyota's Prius. And from what I could tell it sounds like their system wouldn't even fit in a small vehicle. If their system is really what they claim, I would fill the tank about twice a year. That's awesome. Too bad it'll probably add twenty grand to the cost of the vehicle.
So technically one can say that AM General is not a commercial automaker since they sell most if not all of their products to military.
As a taxpayer, I really hate it when those gullible dolts in the military get hosed for another few million dollars- because I ultimately end up paying for it. And my kids. Grandkids too I imagine. Didn't anyone tell the army that GM sold the Hummer division to a Chinese company? Hello?!? Are any of the DumabA$$e$ in the Pentagon listening to reason or common sense?
I did notice that the only person quoted was conspicuously NOT from the military.
No such thing as lithium-tatinate... Perhaps you meant to write Lithium-TITANATE which is based on lithium-TITANium metals
