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, NextEnergy, DTE Energy, the American Center for Mobility 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.”
The 400kW (1000V/400A, 500A below 800V) extreme fast EV charger developed by Delta Americas boasts three-phase 13.8 kVac medium voltage SiC MOSFET SST topology to provide not only industry-leading 500A charging current , but also grid-to-vehicle energy efficiency as high as 96.5% with a system weighting 4 times less than conventional fast DC EV chargers. The next-generation SST technology also offers essential capabilities for smart grid applications, such as reactive power compensation for voltage stabilization and improved power quality. Moreover, its HVDC power architecture enables connection with renewable energy and energy storage systems (ESS) to lighten the impact on the electricity grid during times of high EV charging demand.
