摘要:
The invention relates to a method and a device for the location-independent power intake of and/or location-independent power feed by a mobile storage and consumption unit at a stationary electric vehicle charging station. The method comprises at least the steps of producing a first communication link between the storage and consumption unit and the electric vehicle charging station when the mobile storage and consumption unit spatially approaches a stationary electric vehicle charging station, a unique ID number being allocated to the storage and consumption unit and the electric vehicle charging station having an electricity counter with a counter number, transmitting a data packet which contains at least the ID number and the counter number via a second communication link to a billing server, allocating the storage and consumption unit to a power supplier using the ID number and allocating the electricity counter to a distribution network operator using the counter number and using the respective data stored on the billing server, clearing the electric vehicle charging station upon successful allocation on the billing server, supplying power to the storage and consumption unit or feeding power from the storage and consumption unit to the electric vehicle charging station and transmitting the quantity of electricity withdrawn from or fed into the electric vehicle charging station to the billing server via the communication link.
摘要:
The invention relates to a mobile electricity meter for the location-independent power intake of and/or for the location-independent power feed by a mobile storage and consumption unit at a stationary electric vehicle charging station, said storage and consumption unit having a rechargeable battery. The mobile electricity meter is integrated into a mobile storage and consumption unit or can be attached to such a unit and comprises as the main components at least one central control unit, an actuator for actuating a switch in order to start or stop the charging process and/or the feeding process, a communication module for processing data from the control unit for communication with the electric vehicle charging station and/or with a data management system and for converting incoming signals to data that can be processed by the control unit, a measuring device for measuring the flowing electrical energy during charging of the rechargeable battery of the mobile storage and consumption unit or during feeding to the electric vehicle charging station, an encryption module for encrypting the data generated by the control unit and a device which is connected to the measuring device and which signs the data acquired by the measuring device with an ID number.
