Delta Demonstrates 400kW Solid State Transformer-Based Extreme Fast EV Charger

Delta Electronics (Americas), Ltd., subsidiary of Delta Electronics, Inc. (Delta) demonstrated a next-generation SiC MOSFET solid state transformer (SST)-based 400kW extreme fast EV charger to its U.S. DOE grant program partners General Motors (GM), DTE Energy, NextEnergy, Virginia Tech's Center for Power Electronics Systems (CPES), and the American Center for Mobility.

At the event, key representatives from all program partners, shared their vision on how Delta's extreme fast EV charging solution, which facilitates industry-leading charging current up to 500 Amps, is expected to accelerate the adoption of e-mobility across North America.

The demonstration event featured GM's all-electric supertruck, the GMC HUMMER EV.

Kelvin Huang, President of Delta Electronics (Americas), said, "Collaborating with GM, DTE Energy, NextEnergy, the American Center for Mobility, CPES and the DOE has been a privilege. By combining our joint prowess in energy management, e-mobility and R&D, we are building the EV charging infrastructure of the future. Guided by its corporate mission, 'To provide innovative, clean and energy-efficient solutions for a better tomorrow', Delta continuously develops ground-breaking technologies and fosters long-lasting relationships with partners to help achieve mankind's sustainability goals. This is how Delta, a member of the RE100 and EV100 initiatives, has been uniquely able to deliver more than 1.5 million EV chargers worldwide over the past decade."

"We appreciate the opportunity to participate in the development of Delta's advanced charging system," said Tim Grewe, director of Electrification Strategy at GM. "The results are encouraging, and we look forward to continued collaboration as we work toward an all-electric future."

"Extreme fast charging will accelerate the adoption of electric vehicles, bringing us closer to a cleaner energy future," said Richard Mueller, DTE Energy Technology, Standards and Interconnection manager. "A key aspect of the new technology is the ability to connect directly to medium voltage distribution and provide faster, more efficient charging compared to lower voltage chargers. This project will give DTE and its project partners significant insight into how these fast chargers can be integrated safely, reliably and with ever growing numbers into the grid."   

"NextEnergy is proud to support Delta Electronics and partners to provide the siting analysis and facilitate the initial testing of the extreme fast charger. Commercializing new charging technology will address range anxiety and accelerate the adoption of EV's to meet our climate and environmental goals," said Jim Saber, CEO of NextEnergy.
