Technology Description:

Stanford University is developing an EV battery that can be used as a structural component of the vehicle. Today’s EV battery packs only serve one purpose: electrical energy storage. They do not carry structural loads during operation or absorb impact energy in the event of a collision. Stanford’s new battery design would improve upon existing technologies in four key areas: 1) structural capabilities, 2) damage and state sensing systems, 3) novel battery management and thermal regulation, and 4) high-capacity battery cells. Stanford’s research will result in a multifunctional battery chassis system that is safe and achieves high efficiency in terms of energy storage at low production cost. The integration of such a battery system would result in decreased overall weight of the combined vehicle and battery, for greater EV range.

Potential Impact:

If successful, Stanford’s battery system would reduce overall vehicle weight more than 40% by serving as a structural component, resulting in increased driving range.

Security:

The mass adoption of EVs would diminish the demand for petroleum, dramatically reducing U.S. dependence on foreign oil.

Environment:

Greater use of EVs would reduce U.S. greenhouse gas emissions, 28% of which come from the transportation sector.

Economy:

Technological advancements from the RANGE program could enable EVs to travel significantly further on a single charge at a much lower cost than that of current EVs and conventional vehicles.
