Abstract
A method is provided for control of a system of charging points composed of at least two charging points, each of which is outfitted with at least one solid oxide fuel cell and with a high-voltage battery electrically connected or electrically connectible to the solid oxide fuel cell, where the charging points are adapted to provide electrical charging current via a converter at an interface for connection to a battery operated consumer. The method includes: checking the state of charge of the high-voltage battery of a first charging point by which the electric energy will be provided for charging the consumer via the interface, charging the high-voltage battery of the first charging point, and possibly that of the consumer, by a current-generating operation of the solid oxide fuel cell of the first charging point, if the state of charge of the high-voltage battery of the first charging point has fallen below a first limit value, and charging the high-voltage battery of the first charging point by means of an electric current provided by a second charging point if the state of charge of the high-voltage battery has fallen below a second limit value, located below the first limit value.
