Advanced Energy Storage System for Electric Vehicle Charging Stations for Rural Communities in the Pacific Northwest

As electric vehicles (EV) become more available, a pervasive and dependable charging network must be built. The electric power grid serves many remote places, but EV charging stations are not widespread and electric distribution is not always reliable in rural areas. This project builds on a previous NASA investigation that the authors performed to create the field regulated reluctance motor-generator (FRRM) as an energy storage device on the surface of the moon. At NASA Technology Readiness Level (TRL) 2 (concept formulation, simulation of basic properties and algorithms, and elementary experimental investigation of underlying science), the data-driven solution† appears promising. The FRRM forms the basis of exceptionally energy efficient storage in support of remote EV charging in an effective and reliable manner. The FRRM’s rotor itself is the rotating energy-storing mass, making for a compact bidirectional machine. Using advanced power electronic converter technology, the authors store energy and recover energy using the FRRM’s unique topology. Although a prototype based on this design was not finished, the FRRM design has been documented in three Masters theses.
