Electric Vehicle Direct-Current Hub (EVDCH)

Project Innovation

This project will develop and demonstrate an innovative medium-voltage direct current (MVDC) power distribution architecture to convert medium-voltage alternating current (MVAC) power from the grid to MVDC power, which is then distributed to direct current fast chargers. The key components of the proposed Electric Vehicle Direct Current Hub (EVDCH) architecture will be a solid-state transformer, a network of charge station converters to interface with the electric vehicles being charged, and a power distribution network connecting these components via a MVDC distribution bus. This innovative architecture will then be demonstrated at a charging station serving medium- and heavy-duty vehicles.
