Select research projects by the U.S. Department of Energy (DOE) are concentrated on developing electric vehicle systems that can recharge promptly at high power levels, lessening typical charge times to 15 minutes or less using a connector or wireless fast charging system.

The DOE Vehicle Technologies Office within the Office of Energy Efficiency and Renewable Energy invests in early-stage research to enable private-sector development and commercialization of affordable, energy efficient transportation technologies that can reinforce the nation's energy security, support U.S. economic growth, and offer consumers and businesses additional transportation options.

According to a recent DOE study, recharging current EV batteries takes much longer than refueling the average liquid-fueled internal combustion vehicle. Slower charge rates are required to allow the lithium-ions to penetrate to the deepest portions of the active material on the electrode. Charging at too high a rate creates a risk for lithium plating, increased battery temperature, and other detrimental side chemical reactions which decrease life and performance characteristics of the batteries.

The projects announced this week will support advanced DOE research on batteries and electrification designed at lowering battery pack cost to under $100 per kilowatt-hour, increasing range to over 300 miles, and charging in under 15 minutes or less by 2028.
