Delta Gets DOE Grant To Develop GaN-based Charger For Electric Vehicles

News

Designs for on-board charger will target energy efficiency better than 95 percent

Delta Products Corporation (DPC), based in Fremont, CA, has announced its participation in a US Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) $3.0 million award for the development of a high-efficiency, high-density, 6.6kW bidirectional on-board charger for plug-in Electric Vehicles (PEVs).

The on-board charger will use novel designs based on GaN power switches that target energy efficiency better than 95 percent and reduce volume and mass by 30 percent to 50 percent compared to today's technology.

The EERE research program will be a collaboration platform for industry and academia. Delta, as a Tier-1 automotive supplier, will be partnering with FCA US LLC, a member of the Fiat Chrysler Automobiles NV (FCA) family of companies, Transphorm, a pioneering company in GaN power devices, and Virginia Tech's Center for Power Electronics Systems.

'Delta is pleased to be working closely with EERE and our partners on this project to develop and commercialise 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.' said M.S. Huang, president of Delta Products Corporation. 

Delta has developed an energy-efficient solution for PEV on-board chargers, DC-DC converters, fast charger modules, battery disconnect units, and off-board charging station and site management systems.
