AC-to-DC Ultra-Fast EV Charger
Technology Description:
Marquette University will develop a small, compact, lightweight, and efficient 1 MW battery charger for electric vehicles that will double the specific power and triple power density compared to the current state-of-the-art. The team aims to use MOSFET switches based on silicon carbide to ensure the device runs efficiently while handling very large amounts of power in a small package. If successful, the device could help to dramatically reduce charging times for electric vehicles to a matter of minutes - promoting faster adoption of electric vehicles with longer range, greater energy efficiency, and reduced range anxiety.
Potential Impact:
If successful, CIRCUITS projects will enable further development of a new class of power converters suitable for a broad range of applications including motor drives for heavy equipment and consumer appliances, electric vehicle battery charging, high-performance computer data centers, grid applications for stability and resilience, and emerging electric propulsion systems.
Security:
More robust power electronics that withstand higher operating temperatures, have increased durability, a smaller form factor, and higher efficiency will significantly improve the reliability and security of a resilient electrical grid.
Environment:
Low cost and highly efficient power electronics could lead to more affordable electric and hybrid-electric transportation, greater integration of renewable power sources, and higher efficiency electric motors for use in heavy industries and consumer applications.
Economy:
Electricity is the fastest growing form of end-use energy in the United States. High performance, low cost power electronics would enable significant efficiency gains across the economy, reducing energy costs for businesses and families.
