Beyond Li-Ion Batteries in Electric Vehicles (EV)

Description:

TECHNOLOGY AREA(S): Ground Sea

OBJECTIVE: Develop the next generation energy storage device for future U.S. Army vehicle platforms, to include hybrids and fully electric vehicles.

DESCRIPTION: In the next generation combat vehicle power generation, energy storage, energy recharge, and energy distribution capabilities will be critically important. Full or partial electrification of a vehicle will enable significant improvements in offensive capabilities, agility & maneuverability, extended operational duration, on-board and exportable power, and reduced signatures for vehicles and mobility systems.To support the creation of a Highly Electrified Platform (HEP), there is a need for new energy storage technologies. The HEP will have extremely high energy demands that will require the vehicle to store several Megawatts of energy to ensure full system functionality in all operational environments across the range of military operations, from training to counter-insurgency to full scale war. This program of effort seeks to identify technology that: -Provides, at a minimum, a specific energy of 400 watts per kilogram; -Is capable of recharge at a rate of >2C; and, -Maintains the same safety and reliability standards as today’s Li-Ion batteries.Awards made under this topic will be for a maximum of $50,000 with a three month period of performance.The Phase I Option period amounts and durations are not changed.

PHASE I: Determine technical feasibility of battery reaching above standards. Develop preliminary storage technology design, model key elements, and identify subcomponents that demonstrate clear path towards meeting requisite minimum standards with a robust safety profile.Phase I deliverables include a design review including expected device performance, and a final report including Phase II plans.Awardees selected for this topic will receive a maximum of $50,000 and have a period of performance of three months. Awardees also have the ability to voluntarily participate in an Army Application Lab cohort program. Companies will kick off the SBIR on location, meeting with end users, getting access to relevant equipment, and talking with key stakeholders. Virtual office hours, to be taken advantage of as desired, will be held weekly throughout the 12 week period of performance. Midway through there will be a virtual touch point with stakeholders to answer questions that may have arisen during the company's concept design week preparations. The final week of the program will involve an in-person outbrief to key stakeholders and AAL. While the cohort programming will be provided free of charge, participating companies must travel and participate out of company internal operating budgets. Proposers that plan to participate in the cohort (if awarded a Phase I) are encouraged to include travel costs for two cohort trips, within the continental US, of 2-3 days each for the in person programming. Details will be provided to awardees under this topic at Phase I award.

PHASE II: Develop a prototype of the battery to the specifications determined in Phase I design study. Conduct a formal risk assessment of the cell and thermal monitoring solutions for the transportation, storage and use of the battery in operational environments. Phase II deliverables include delivery of a prototype for further Army evaluation, as well as quarterly and final reports detailing design and performance analysis of the prototype.Awardee(s) of this topic will have the ability to voluntarily participate in quarterly soldier touch-points, a 1-2 day trip within the continental US. Touch point will be provided free of charge, however participating companies must travel and participate out of company internal operating budgets. Soldier touch point details will be provided to awardee(s) under this topic at Phase II award.

PHASE III: Develop a manufacturing ready product design, capable of integration with at least one Army vehicle platform, and demonstrate technology integration as part of a vehicle system. Low rate production will occur as required. Potential commercial uses include electric commercial vehicles, trucks, and trains; and mass transportation infrastructure.
