Electrical automobiles are, at coronary heart, cellular vitality storage units, and the US firm Dannar is taking full benefit. Dannar has give you a sequence of wheeled electrical workhorses geared toward knocking out diesel mills and different off-road gear. They might look bizarre, however they sport packs of highly effective EV batteries from BMW, and they’re featured in a high-impact Division of Protection showcase for brand spanking new prolonged length vitality storage applied sciences.

BMW EV Batteries For A Diesel-Killing Cell Power Storage Unit

Dannar and BMW started co-developing i3 EV batteries for off-road use round 2015, in a car described as a “first-of-its-kind electrical heavy-duty car for infrastructure upkeep and catastrophe response.”

By 2017 they have been able to roll, and Dannar introduced that its new Cell Energy Station® off-road work automobiles would deploy BMW i3 EV batteries. “The MPS can carry a number of BMW i3 battery packs on-board its metal ladder body and 40,000 lb. rated axles,” Dannar defined again in 2017.

“Customized configurations of a number of BMW batteries present applicable clear vitality for single day or a number of day work necessities,” they added.

Relatively than relaxation on the laurels of zero emission workability, Dannar front-loaded the Cell Energy Station with a Lego-like capacity so as to add and subtract varied off-the-shelf components and gear, enabling its house owners to make use of the identical car for various duties, beneath completely different seasonal situations.

US DOD Eyeballs i3 EV Batteries For Cell Power Storage

In 2020 the mashup between Dannar’s cellular vitality storage unit and BMW’s EV batteries quickly caught the attention of the AFWERX energy innovation challenge, a technology transition initiative of the US Air Force.

The Air Power connection has out of the blue blossomed-out into a serious Protection Division initiative beneath the banner of the Defense Innovation Unit.

Earlier this week, DIU introduced the brand new “Prolonged Length for Storage Installations” undertaking beneath the Air Power and Navy, geared toward demonstrating three new applied sciences. Along with Dannar’s cellular lithium-ion EV batteries, the initiative options stationary flow batteries from CellCube and Redflow.

“The Prolonged Length for Storage Installations (EDSI) undertaking will make resilient backup energy programs a actuality for DoD installations and operational vitality platforms by growing the minimal energy threshold and uptime that batteries, bases and battlefield vitality, and sourcing use can all keep on-line,” DIU defined in a press launch earlier this week.

“Since battery programs can draw energy throughout non-peak instances for decrease value, the EDSI effort will assist installations decrease their energy inputs and attracts to isolate excessive energy masses when normal demand for electrical energy is excessive in containers that may be stationary and cellular,” they added.

Dannar will contribute 4 completely different configurations of its i3 EV battery answer to the undertaking. The automobiles will function in help of recent electrical VTOL (vertical takeoff and touchdown) plane at two Air Power websites, and take part in a vehicle-to-grid/vehicle-to-vehicle resilience analysis initiative at three websites beneath the umbrella of the Navy and Marine Corps.

EV Batteries To Cost Flying Electrical Autos

The important thing phrase within the DIU undertaking is “prolonged.” That’s a giant distinction in scale in comparison with lengthy length vitality storage programs. Ideally, long duration energy storage systems can retailer sufficient clear kilowatts from renewable sources to supply electrical energy for a full day, a number of days, weeks, months, and even seasons at a time. In distinction, the rule of thumb for conventional lithium-ion battery arrays is at present round six hours, although programs with an eight-hour length are starting to emerge.

DIU is setting the bar at “prolonged,” outlined as the power to supply from 50 kilowatts as much as 1 megawatt for at a minimal of eight hours straight.

That will appear low in comparison with lengthy length programs, however apparently it’s sufficient to construct new efficiencies into eVOTL operations.

DIU cited AFWERX Agility Prime Engineer, Brooke Ezell, who defined that new vitality storage expertise will “will allow us to fill gaps in present electrical infrastructure and handle vitality resiliency and charging limitations associated to eVTOLs whereas additionally growing the variety of eVTOL flights doable per day and using extra renewable vitality sources.”

The Huge Image On Cell Power Storage

The brand new DIU initiative provides one more component to the position of the US navy in pushing the electrification envelope. The Division of Protection turned generally known as an early adopter of utility-scale solar energy throughout the Obama administration, with vitality resilience and safety topping the checklist of near-term advantages. Grid resilience and environmental benefits to the communities surrounding navy services have additionally factored into the renewable energy push.

The Protection Division’s forays into microgrids, electrical automobiles, and new EV batteries have obtained considerably much less media consideration, particularly throughout the Trump years when presidential enthusiasm for saving the planet was on the wane.

Nonetheless, work continued apace, and new solid-state EV batteries might assist open up new alternatives to fill the navy’s want for rugged vitality storage expertise that may face up to excessive environments.

The Stable State EV Battery Of The Future

Varied branches of the US navy have already begun eyeballing strong state expertise. BMW and plenty of different leading automotive stakeholders have additionally begun investing in varied strong state ventures (see extra CleanTechnica protection here), so don’t be stunned for those who see EVs from Dannar sporting a strong state BMW battery some day.

Stable state or not, EV batteries have but to discover a footing in tanks and different heavy-duty navy functions, however they’re starting to work their approach into light duty applications.

The Protection Division has additionally been experimenting with hydrogen fuel cells for zero emission mobility. As with EV batteries, tanks seem like off the desk in the meanwhile, although gasoline cell auxiliary power might nonetheless be in play as a spread extender.

If the Protection Division decides to leap on the gasoline cell bandwagon with each toes ahead, Dannar seems to be prepared. Final yr the corporate introduced a brand new wrinkle in its fuel cell collaboration with the US agency Introduction Applied sciences, geared toward growing a zero emission vary extender for Dannar electrical automobiles.

If all goes based on plan, gasoline cells might change Dannar’s present vary extension answer, which consists of a 50-gallon gasoline tank.

The 2 firms additionally plan to develop a big scale, gasoline cell-enabled charging station for electrical automobiles.

Army functions stay to be seen, however Advent has some attention-grabbing connections of its personal to mix with Dannar’s Protection Division hookup.

Introduction has been working with three Power Division laboratories — Los Alamos, Brookhaven, and the Nationwide Renewable Power Laboratory — on a gasoline cell commercialization undertaking beneath the L’Innovator umbrella of the Los Alamos lab, with an help from the ARPA-E funding workplace.

The purpose is to develop a extra sturdy, lengthy vary fuel cell for heavy duty applications, with a concentrate on a brand new polymer-based materials that resolves  issues about overheating.

Apparently all that onerous work has paid off. “Implementing the composite polymer electrolyte achieved an influence density of practically 800 milliwatts per sq. centimeter at 160 levels Celsius, a 60% enchancment in comparison with phosphoric acid-based gasoline cells,” Los Alamos reported final spring.

The L’Innovator program has been prolonged into 2024, so keep tuned for extra information on Introduction and Dannar.
