The Extreme Fast Charging (XFC) project will: 1) perform modeling, state estimation, and life-aware model-predictive controls of on-vehicle battery systems; 2) perform modeling for thermal behavior of fast-charging wireless power transfer modules; 3) perfom testbed demonstrations of embedded coils in static- and semi-static applications; 4) perform high-performance fast wireless charging, 5) perform investigation of site level power distribution, system modeling, and modular power converter development; and 6) perform power converter state of health monitoring, prediction, and control.
