A method for bidirectional charging of an electric vehicle (12, fig. 3) traction battery (10, fig. 3) on the basis of a charging profile which determines a charging mode such as vehicle to grid, V2G, or grid to vehicle, G2V. The charging profile (CP) is determined by an electronic computing device (14, fig. 3) which applies: a first prediction algorithm characterizing an anticipated battery usage, or user profile (UP), on the basis of user data; and a second prediction algorithm characterizing a state of a charging infrastructure, or energy profile (EP) on the basis of utility data. The charging profile may be approved by a user input and is used to determine the charging power, a charging time, or a charging duration. The charging profile may be adapted from a default profile (SSD), perhaps based on user input. The user data may be a location, driving or charging behaviour, or calendar or navigation data. The utility data is retrieved from a server (18, fig. 3) and may comprise electricity prices or load data. During the charging process, started upon connection to a charging point (16, Fig. 3), a state of the traction battery is determined by means of a control device. Discharging may prompt an error message or a change in the charging process.
