Delta Developing Super-Lightweight 95% Efficient 6.6-kW Bi-Directional Onboard Charger
Delta Products Corporation, headquartered in Fremont, CA, was recently awarded $3.0 million by the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) for a new project of developing a high-efficiency, high-density, 6.6kW bidirectional on-board charger.
This one will be special not only because of its bidirectional capability, but also its use of Gallium Nitride (GaN) power switches.
At least 95% energy efficiency and volume/mass reduction by 30% to 50% (“compared to today’s technology“) is the target.
“The EERE research program will be a collaboration platform for industry leaders in different fields and a world-renowned research university. Delta, as a Tier-1 automotive supplier, will be partnering with FCA US LLC, a member of the Fiat Chrysler Automobiles N.V. (FCA) family of companies, Transphorm, a pioneering company in GaN power devices, and Virginia Tech’s Center for Power Electronics Systems.”
M.S. Huang, president of Delta Products Corporation stated:
“Delta is pleased to be working closely with EERE and our partners on this project to develop and commercialize the next generation of on-board EV chargers. The development of a smaller, lighter, less expensive and more efficient bidirectional on-board charger will be an enabling technology for affordable, fuel efficient plug-in electric vehicles and vehicle-to-grid applications.”
Delta Group has for several years been engaged in electric mobility supplying fast chargers and other equipment like on-board chargers and DC-DC converters.
