1. A method for providing information to a user during charging of an electric energy accumulator of a motor vehicle by a charging station, comprising:
receiving, via a first communication device of the user, position information regarding a position of the user or a position of the first communication device from a position determination device;
receiving, via the first communication device, position information regarding a position of the charging station from a second communication device of the charging station;
receiving, via the first communication device, information regarding a connection time at which the motor vehicle is connected to the charging station from the second communication device;
receiving, via the first communication device, a time stamp from the second communication device;
synchronizing, via the first communication device, a clock of the first communication device with a clock of the second communication device based on the time stamp;
receiving, via the first communication device, information regarding a state of charge of the electric energy accumulator from the second communication device;
determining, via the first communication device, a predicted end time for the charging of the electric energy accumulator based on the state of charge;
receiving, via the first communication device, information regarding a parking time, from the second communication device, wherein a fee is incurred for blocking the charging station upon expiration of the parking time after the connection time or upon expiration of the parking time after the predicted end time of the charging of the electric energy accumulator;
determining, via the first communication device, a first time requirement for movement of the user to the charging station via a first means of transportation;
determining, via the first communication device, a first triggering time at which a first triggering condition is fulfillable based on the first time requirement for movement of the user to the charging station;
upon fulfillment of the first triggering condition, outputting a first notification message via the first communication device of the user,
wherein the first notification message includes information that indicates the first means of transportation,
wherein the first notification message is output at least the first time requirement for movement of the user to the charging station before expiration of the parking time after the connection time or before expiration of the parking time after the predicted end time of the charging of the electric energy accumulator, such that the user is able to move to the charging station via the first means of transportation before the fee is incurred for blocking the charging station;
determining, via the first communication device, a second time requirement for movement of the user to the charging station via a second means of transportation, wherein the second means of transportation is different from the first means of transportation;
determining, via the first communication device, a second triggering time at which a second triggering condition is fulfillable based on the second time requirement for movement of the user to the charging station;
wherein the second triggering time is different from the first triggering time,
upon fulfillment of the second triggering condition, outputting a second notification message via the first communication device of the user,
wherein the second notification message includes information that indicates the second means of transportation, and
wherein the second notification message is output at least the second time requirement for movement of the user to the charging station before expiration of the parking time after the connection time or before expiration of the parking time after the predicted end time of the charging of the electric energy accumulator, such that the user is able to move to the charging station via the second means of transportation before the fee is incurred for blocking the charging station.
