WASHINGTON \u2014 GM Defense is working with the Defense Innovation Unit on two projects aimed at bringing electric power to the battlefield \u2014 and potentially paving the way for the U.S. Marine Corps to feel comfortable fielding an all-electric vehicle down the road.<\/p>\n\n\n\n

The company, a subsidiary of General Motors, is leveraging battery technology investments from the commercial automobile sector and applying it to the defense space, Paul Beaker, GM Defense chief engineer and director of advanced product development, told Defense News.<\/p>\n\n\n\n

GM Defense first won a contract with DIU in September<\/a> for the Jumpstart for Advanced Battery Standardization program. JABS will test and analyze a handful of mature battery packs from industry, and create standards that can be used in future defense programs.<\/p>\n\n\n\n

Noting that these battery packs could help turn any ground vehicle into a hybrid vehicle, Daphne Fuentevilla, the deputy director of the Navy\u2019s operational energy office, said in a February DIU news release that \u201cour strategy is to learn how large of a building block we can leverage, how to package the commercial technology into non-proprietary defense interfaces, and how to integrate batteries evolving at the speed of industry into defense platforms with static structures.\u201d<\/p>\n\n\n\n

GM Defense\u2019s testing will begin late this year and run through 2025. Early testing will focus on a single Ultium battery, which runs GM\u2019s electric cars and trucks. The testing will progress to include larger battery packs and, eventually, the company\u2019s four-seat Infantry Squad Vehicle outfitted with a battery module that would power communications systems, counter-drone weapons and other energy-hungry tools in the field.<\/p>\n\n\n\n

Last month, GM Defense won a second contract with DIU<\/a> to take on expeditionary power.<\/p>\n\n\n\n

The Marine Corps envisions sending out small groups of Marines to remote locations on beaches, islands and more without much infrastructure. These units would have to pack everything they need, including power.<\/p>\n\n\n\n

Beaker said today\u2019s remote command posts and expeditionary camps might receive power from a tactical microgrid that includes six diesel generators and a power distribution system. The generators each make 60 kilowatts of power, which is three times more than many whole-house generators make \u2014 but they\u2019re either fully on or fully off, and so Marines could waste a lot of diesel fuel powering big generators during times they only need a small amount of power.<\/p>\n\n\n\n

Instead, through DIU\u2019s Stable Tactical Expeditionary Electric Power program, or STEEP, Beaker said the company wants to replace one or two of the generators with large battery packs that could store the extra electricity. In this way, users wouldn\u2019t waste energy, and Marines could draw from that stored energy if they need to keep a low signature or power a small system that doesn\u2019t necessarily require turning on a big generator.<\/p>\n\n\n\n

Beaker said the addition of the Ultium batteries would reduce the overall fuel consumption and therefore the need for resupply, as well as reduce wear and tear on the generators and extend their lives.<\/p>\n\n\n\n

\u201cWe\u2019re finishing up our design on this, and we\u2019ll build seven prototypes and deliver those for testing by DIU and the Marine Corps early 2025,\u201d he said.<\/p>\n\n\n\n

Though the battlefield electricity issue will become increasingly important as the Marines continue to embrace concepts like Expeditionary Advanced Base Operations, Beaker said the firm hopes the battery performance in JABS and STEEP will convince Marine Corps leaders to take the plunge on putting all-electric vehicles into the field.<\/p>\n\n\n\n

\u201cAs our military talks about electrifying their fleet, we started down a journey to learn,\u201d he said.<\/p>\n\n\n\n

The company first created its All-Electric Military Concept Vehicle based on the commercial Hummer EV design, but it was clear the service wasn\u2019t comfortable with it yet \u2014 particularly due to concerns about where in a battlefield the EV batteries could recharge.<\/p>\n\n\n\n

Beaker said the company evolved its design, adding a 12-kilowatt diesel generator and a fuel tank to the vehicle so operators would essentially haul around their own recharging capability. That still wasn\u2019t enough to ease concerns, he explained.<\/p>\n\n\n\n

So GM Defense now has a family of Next Generation Light Tactical Wheeled Vehicle designs that hew more toward a traditional hybrid vehicle, creating a lot of energy from the diesel engine and storing some of that power for times when the vehicle needs to remain off to limit its heat and sound signature.<\/p>\n\n\n\n

Beaker said GM Defense will offer one version of this platform for Canada\u2019s light utility vehicle competition, and another version for the U.S. Army\u2019s Electric Light Reconnaissance Vehicle program.<\/p>\n\n\n\n

The company is also designing an autonomous version of this vehicle that could haul electronic warfare, short-range air defense, reconnaissance or logistics payloads into the battlefield.<\/p>\n\n\n\n

Though the Marine Corps doesn\u2019t have any upcoming competitions for a hybrid or all-electric vehicle, Beaker said the work with DIU could give the service the confidence in battery technology to pursue an EV.<\/p>\n\n\n\n

He said it was a matter of \u201cnot if, but when\u201d the Marines have to replace the Humvee. And GM Defense wants to have its Next Generation Light Tactical Wheeled Vehicle matured and ready to compete at that time.<\/p>\n\n\n\n

Additionally, \u201cin our conversations with Marine Corps leadership, there seems to be a recognition that there needs to be a platform between the [ultralight tactical vehicle<\/a>] that can fit in an Osprey, and the [Joint Light Tactical Vehicle]. It seems like there\u2019s a need for something in between, and we think that\u2019s where either the [Infantry Squad Vehicle] and\/or the next-gen tactical vehicle fit in,\u201d Beaker said.<\/p>\n","protected":false},"excerpt":{"rendered":"
