Measurements on vehicle to grid application in industrial power grid for peak load reduction: Robust bidirectional charger for series production electric and plug-in hybrid vehicles

摘要

The combination of “electric mobility” and “renewable energy production” heavily demands for energy storage systems. Investigations of technical possibilities to use the stored energy of electric vehicles (EV) and so called plug-in hybrid electric vehicles (PHEVs) for smoothing the grid load and reduce power peaks are inalienable. Within the limits given by the car's battery management system consumption-driven charge and discharge signals could be used for effective integration in V2G systems. This paper will give a detailed overview of a system for bidirectional charging in an industrial grid. First real measurements and test results are given to proof the concept and show the opportunities.
