Synchrophasors, Active Transformers, and Energy Storage in the Context of Fast Charge EV Infrastructure

Charles W. Botsford
2010 World Electric Vehicle Journal  
Electric vehicle (EV) fast charging capabilities, and availability of fast charge infrastructure, are perhaps the greatest remaining obstacles in the future widespread use of EVs. Solving fast charging paradigms and issues will enhance driver and electric utility acceptance of EVs. Potential impact to the grid is one of the perceived issues. The technologies to transform EV fast chargers, a grid load, into a valuable grid asset, exist in the form of components and a system approach that

This would allow this system approach to become commercial as the widespread adoption of EVs unfolds. Grid-Level Energy Storage. Less certain is the prospect for the cost-effectiveness of grid-level energy storage. This technology is at the demonstration phase and major funding comes from the ARRA Stimulus EVS25 World Battery, Hybrid and Fuel Cell Electric Vehicle Symposium 6 EVS25 World Battery, Hybrid and Fuel Cell Electric Vehicle Symposium 7
