Abstract: An inductive drawing or feeding device for inductively drawing off or feeding in electrical energy/electricity by electric vehicles is connected to a power grid. The inductive drawing or feeding device includes a measuring device configured to measure at least one physical parameter representing the electrical energy inductively transmitted through the associated drawing or feeding device. The inductive drawing or feeding device also includes an identifier for identifying the owner of the connection of the inductive drawing or feeding device. The inductive drawing of feeding device further includes a comparing device configured to compare the at least one physical parameter measured at a connecting side with at least one physical parameter measured at a drawing off or feeding side.

Abstract: The invention relates to a metering and measuring point system for measuring and metering the electrical energy drawn off a connection device or fed in the connection device by a consumption and/or generation unit at a fixed geographical point, comprising (a) an identifiable stationary connection device as well as (b) an identifiable mobile or non-stationary functional unit, the latter comprising respective devices for (b1) detecting the identifier of the connection device, (b2) metering and measuring the electrical energy drawn off and/or fed in the recognized connection device, (b3) storing the determined metering and measuring data and the determined identifier of the respective connection device being used and (b4) reading out the stored data. The invention further relates to a method for mobile/non-stationary measuring, metering and billing/clearing of the electrical current.

Abstract: A metering and measuring point system for measuring and metering electrical energy/electricity drawn off and/or fed into a drawing off and/or feeding device at a fixed geographical point by a consumption unit, comprises one or more stationary drawing off and/or feeding devices that are connected to the power supply and configured for drawing off and/or feeding in electrical energy/electricity by means of consumption/generation units and at least one identifiable non-stationary functional unit for measuring and metering electrical energy/electricity that is conductively, via an electric conductor or inductively, drawn off or fed into one or more stationary drawing off and/or feeding devices by consumption/generation units.
