摘要:
A method for controlling charging operations of a plurality of electric vehicles is proposed, which method comprises the following steps of: - providing a data record which comprises arrival times, departure times and charging energies of the electric vehicles during a first period; - determining a minimum total charging capacity (42) from the data record by means of a computing apparatus, wherein the minimum total charging capacity (42) determined makes it possible to approximately completely charge each electric vehicle between the arrival time (114) and the departure time (112) thereof; and - charging the electric vehicles with at most the minimum total charging capacity (42) determined during a second period following the first period.
摘要:
The invention relates to a charging station for charging an electric vehicle and to a charging post thereof. Said charging post can be lowered into the ground by means of a lifting device such that it is doesn't become a physical obstacle or optically impair the environment and is not damaged due to external influences.

The invention relates to a coil system for the contactless magnetic navigation of a magnetic body (1) in a work space, wherein the coil system comprises a plurality of coils and a current controller for controlling the respective currents in the plurality of coils. In order to navigate the magnetic body (1) to a variably predeterminable position (P) in the work space, the current controller is designed such that the currents in the plurality of coils are such that the magnetic forces (F 1 , F 2 , F 3 , F 4 ) generated by the currents and acting upon the magnetic body (1) at multiple positions (P 1 , P 2 , P 3 , P 4 ) at the edge of a convex environment (Ω) around the predetermined position (P) are directed into the environment (Ω). The coil system according to the invention has the advantage that a movement of the magnetic body toward a spatial position is achieved without any mechanical movement of the coil system and without a positioning system for determining the position of the magnetic body. The coil system is utilized particularly in a medical device, wherein a magnetic body in the form of a probe is moved in the body of a patient. In this way, fast navigation of the probe in the patient’s body can be achieved without mechanical movements of the patient table or of the coil system.
