  • Patent number: 10734820
    Abstract: Electric power is provided to motor vehicles via a respective outlet station. A number of outlet stations are connected to a common electric power supply, each with an interface towards a control node. Over the interfaces, the outlet stations receive operation commands from and send status messages to the control node. The control node allocates a fraction of the common electric power supply to each outlet station to which a motor vehicle is connected. The fractions are allocated such that a sum of all fractions represent a total delivered power, which is less than or equal to a predefined maximum level for the common electric power supply. If an interface between an outlet station and the control node is broken, the outlet station is configured to apply a power supply scheme according to which the outlet station is only allowed to deliver electric power up to a level prescribed by a predefined principle stored in each of the outlet stations.
