METHOD AND DEVICE FOR CHARGING AN ELECTRIC VEHICLE

The invention relates to a method and to a device () for charging an electric vehicle () with a charging current (I), having a connection () for connecting to a domestic mains supply () connected to a power generating plant (), a power supply grid (), an energy management device (), and possibly an energy storage (), a charging connection () for connecting to the electric vehicle () to be charged, and a control device () for controlling the charging current (I) for charging the electric vehicle (). For optimal utilization of the power of an existing power generating plant (), such as a photovoltaic plant, and thus for particularly cost-effective and efficient charging of the electric vehicle n(), at least one device is provided for determining the surplus power of the domestic mains supply () and the power drawn from the power supply grid () and for comparing them with at least one activation threshold (ESSW) and/or deactivation threshold (ASSW) is provided, and the control device () is designed so that the charging current (I) for charging the electric vehicle () is provided in accordance with the at least two preset charging currents (I), by activating or deactivating the corresponding preset charging current (I) when the corresponding activation threshold values (ESSW) or deactivation threshold values (ASSW) are reached.
