Abstract:
Despite the benefits of transport electrification, such as improved efficiency energy use or reduced en-vironmental impact, a wide spread of incorrectly managed charging facilities can generate problems for the electricity system, mainly in the distribution grids. In recent years, the paradigm is changing and the use of EV charging facilities as support elements for grid operation is being proposed. Following this idea, this document shows a high-power EV charger with a 4-leg grid side for grid support, highlighting among its functionalities the possibility of charging or discharging EV batteries in an unbalanced way or the management of reactive power.
