The DOE will award up to $15 million in a new funding opportunity (DE-FOA-0001808) to encourage the development of what it calls “extreme fast charging” (XFC).
The objective is to develop technology that can recharge a battery in half the time of current fast charging systems.
The new FOA includes two Areas of Interest: XFC itself; and batteries for extreme fast charging.
Projects addressing the XFC Area of Interest should aim to decrease charging times while maintaining currents of less than 400 A, and assure that battery state of charge increases by at least 50% with a 3C or greater rate of charging. Proposals should list planned charger locations including infrastructure requirements, and describe partnerships with governments, suppliers and other entities to support the system design and demonstration.
Area of Interest #2 is Batteries for Extreme Fast Charging. The objective here is to develop battery cells capable of achieving 500 cycles (with less than 20% fade in specific energy) consisting of a 10-minute fast charge protocol, while matching or exceeded current state-of-the-art cell specific energy and cost (greater than 200 Wh/kg and less than $150/kWh). Specific technical interests include: novel electrode and cell architectures; novel electrolytes; active material modifications; and improved additives.
