Electric Vehicles for American Low-carbon Living
The transportation sector is responsible for 28% of greenhouse gas emissions in the U.S., with road-based passenger vehicles accounting for 57% of those emissions. Cars, sport utility vehicles, minivans, and pick-up trucks emit more than one billion tons of CO2 domestically per year. As the U.S. works to decarbonize the transportation sector and increase production of “clean” (zero emission) electricity, electric vehicles (EVs) are compelling alternatives to vehicles with internal combustion engines (ICEs).
The key to EV adoption is a reliable, inexpensive battery that can charge fast and provide improved performance and range retention in cold weather compared to state-of-the-art commercial options. ARPA-E's EVs4ALL program will increase EV market share by developing next-generation battery technologies to significantly improve EV affordability, convenience, reliability, and safety. Program objectives for batteries to accomplish this mission include:
Achieving a charge rate equivalent to 5-15 minutes to restore 80% of cell capacity
Reducing low-temperature battery performance losses by at least 50%
Retaining a minimum of 90% capacity after the battery has delivered 200,000 miles of equivalent and cumulative range
Identifying a compelling pathway to a cost of < $75/kWh at commercial scaleImplementing new and existing protocols to verify safety of new battery chemistries and cell designs
