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

GM recently attended a demonstration of Delta Electronics’ new 400 kW EV fast charger system, which promises a range of benefits and will help to bolster the EV charging infrastructure.
Delta Electronics seeks to produce innovative, clean, and energy-efficient solutions to create the EV charging infrastructure of the future. To that end, the company has developed a next-generation SiC MOSFET solid state transformer (SST)-based 400 kW extreme EV charger system that can provide charging current up to 500 Amps.
The new technology was shown at a recent demonstration event attended by Delta Electronics’ key program partners, including GM. The demonstration was made in conjunction with the GMC Hummer EV. To note, the Hummer EV includes DC fast charging capabilities up to 350 kW.
“We appreciate the opportunity to participate in the development of Delta’s advanced charging system,” said the director of Electrification Strategy at GM, Tim Grewe. “The results are encouraging, and we look forward to continued collaboration as we work toward an all-electric future.”
The new technology is expected to accelerate EV adoption by addressing issues like range anxiety and long charge times. In addition to providing 500 amps of charging current, the new Delta Electronics EV fast charger tech provides grid-to-vehicle energy efficiency as high as 96.5 percent, while the system itself weighs four times less than conventional DC EV chargers. What’s more, the technology integrates systems that are essential for smart grid applications, including reactive power compensation for voltage stabilization. The HVDC power architecture also enables a connection with renewable energy and energy storage systems to lessen the impact on the broader electricity grid during high EV charging demand.
The deployment of this new technology coincides with GM’s overarching vision of zero crashes, zero emissions, and zero congestion. GM hopes to reach an annual EV production capacity of 1 million units in North America by 2025.
