Metering and measuring point system for measuring and metering electrical energy/electricity and method
First Claim
1. A method for monitoring an inductive coupling of an electric vehicle with an inductive drawing or feeding device connected to a power grid, wherein the inductive drawing or feeding device is not provided with a current meter, the method comprising:
- inductively coupling the electric vehicle with the inductive drawing or feeding device;
measuring, at a connecting side of the inductive drawing or feeding device, at least one first physical parameter representing the electrical energy drawn off or fed in by the inductive drawing or feeding device;
measuring, at a drawing off or feeding side of the inductive drawing or feeding device, at least one second physical parameter representing the electrical energy transmitted between the inductive drawing or feeding device and the electric vehicle;
comparing the at least one first physical parameter measured at the connecting side of the inductive drawing or feeding device with the at least one second physical parameter measured at the drawing off or feeding side of the inductive drawing or feeding device; and
disconnecting the inductive drawing or feeding device from the power grid if the compared at least one first physical parameter measured at the connecting side of the inductive drawing or feeding device deviates from the at least one second physical parameter measured at the drawing off or feeding side of the inductive drawing or feeding device in excess of a predetermined difference threshold level.

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.

6. An inductive drawing or feeding device for inductively drawing off or feeding in electrical energy/electricity by electric vehicles, wherein the inductive drawing or feeding device is configured to be connected to a power grid, and the inductive drawing or feeding device comprises:
-
a first measuring device configured to measure at least one first physical parameter at a connecting side of the inductive drawing or feeding device, the at least one first physical parameter representing the electrical energy inductively transmitted through the inductive drawing or feeding device; an identifier for identifying an owner of the connection of the inductive drawing or feeding device; and a comparing device configured to compare the at least one first physical parameter measured at the connecting side of the inductive drawing or feeding device with at least one second physical parameter received from a second measuring device configured to measure the at least one second physical parameter at a drawing off or feeding side of the inductive drawing or feeding device, wherein the comparing device is configured to initiate at least one action if the compared at least one first physical parameter measured at the connecting side of the inductive drawing or feeding device deviates from the at least one second physical parameter measured at the drawing off or feeding side of the inductive drawing or feeding device such that a predetermined difference threshold level is exceeded, the inductive drawing or feeding device is not provided with a current meter, and the at least one action comprises a disconnection of the inductive drawing or feeding device from the power grid.
