Abstract

An electric vehicle charging station is provided. The electric vehicle charging station includes an interface, by way of which the charging station receives energy from an electrical energy supply grid, an energy intermediate storage device for intermediate storage of energy received or transmitted by way of the interface from the electrical energy supply grid, a plurality of output connections for charging electric vehicles and a control unit for controlling the energy intermediate storage in the energy intermediate storage device and for controlling the delivery of energy by way of the plurality of output connections. The control unit is configured to pass energy from the energy intermediate storage device to the plurality of output connections when the energy drawn at the output connections cannot be made available completely using the interface to the electrical energy supply grid.

Dependent claims

An electric vehicle charging station, comprising:

an interface, between the charging station and an electrical energy supply grid, for the charging station to receive energy from and transmit energy to the electrical energy supply grid,
an energy intermediate storage device for intermediate storage of the energy transmitted to or received from the electrical energy supply grid using the interface,
a plurality of output connections for charging electric a plurality of vehicles simultaneously, and
a control unit for controlling intermediate energy storage in the energy intermediate storage device and for controlling delivery of energy using the plurality of output connections in a first operational mode charging the plurality of electrical vehicles coupled to the plurality of output connections with energy from the electrical supply grid via the interface,
wherein the control unit is configured to, in a second operating mode, cause energy to be provided from the energy intermediate storage device to the plurality of electrical vehicles coupled to the output connections if the energy drawn at the plurality of output connections cannot be provided completely by the electrical energy supply grid via the interface,
wherein the control unit is configured to, in a third operating mode and based on a first fault in the electrical energy supply grid, initiate energy intake from the electrical energy supply grid by the intermediate storage device, to remove excess energy from the electrical supply grid to support the electrical supply grid during the first fault, and
wherein the control unit is configured to, in a fourth operating mode and based on a second fault in the electrical energy supply grid, initiate an energy delivery from the intermediate storage device into the electrical energy supply grid to provide additional energy to the electrical supply grid to support the electrical supply grid during the second fault.
