Various embodiments include a storage device for electrical energy, the device comprising: a rechargeable battery; two terminals to connect the battery to at least one of: a supply network, an electrical load, and/or an electrical generator; a control unit to control charging and discharging of the battery; a communication interface configured to provide wireless data access; and a display of machine-readable code including authentication data enabling wireless data access.

Storage device for storing electrical energy

Various embodiments include a method for operating an automation network comprising a gateway device and a plurality of network devices. The methods include: subscribing a network device to subscription data with a respectively associated subscription identifier; publishing data on the gateway device under a identifier; publishing publication data as subscribed subscription data under a subscription identifier corresponding to the publication identifier so each of the plurality of network devices subscribed with the same subscription identifier as the respective identifier receive the data transmitted with the subscription identifier. The respective network devices each comprise: a field device subscribing to, collecting, and/or publishing measurement or control data, and a database subscribing to, storing, providing or publishing the data of the field device, device data about network devices present in the automation network, and data about users of the network devices. The transmission of data takes place according to a single specified protocol.

Method for operating an automation network

A circuit arrangement has a bidirectional AC/DC converter connected to a first side of a DC/DC converter at a DC side of the AC/DC converter via first electric switch. The AC/DC converter is connected to a second side of the DC/DC converter at the DC side of the AC/DC converter via a second electric switch. The first side of the DC/DC converter is connected to a third electric switch and can be connected to an energy storing device via said switch. The second side of the DC/DC converter is connected to a fourth electric switch and can be connected to an energy generating device via said switch. The AC/DC converter can be connected to the electric supply grid at the AC side of the AC/DC converter. A control device controls the switches and the converters.
