1. An energy supply system comprising: a control apparatus, a measurement apparatus, a switch unit, a charging station for a vehicle and a signal transmission apparatus,
the switch unit being designed so that, in an on state, the switch unit connects first conductors of a first line to associated second conductors of a second line and in an off state disconnects the first conductors of the first line from the associated second conductors of the second line,
the charging station being connected electrically to the first line and being a bidirectional charging station to enable energy transmission from the charging station to a vehicle in a charging mode and to enable energy transmission from a vehicle to the charging station in a feed-in mode,
the measurement apparatus being configured to determine at least one phase difference value characterizing the phase difference between a first AC voltage signal at one of the first conductors and a second AC voltage signal at one of the second conductors,
the control apparatus being configured to output a first command by means of the signal transmission apparatus depending on the phase difference value, the first command enabling a vehicle connected to the charging station to change the phase position of a fed-in AC voltage signal in the feed-in mode in order to reduce the phase difference, and the control apparatus further being configured to enable a first change of state of the switch unit from the off state to the on state,
wherein the control apparatus is configured to carry out the first change of state depending on the chase difference value.
