Method for interchanging information data between an electrical load and an item of equipment, and a load recognition unit

Abstract

A method for interchanging information data between an electrical load and an item of equipment arranged between the load and the electric power grid is disclosed. An energy storage device located in a load recognition unit associated with the load is charged during a load recognition phase at start-up of the load. After the energy storage device is charged, data stored in the load recognition unit are repeatedly transmitted in form of a data burst to the item of equipment located between the load and the electric power grid. The data burst includes a preamble and load data; whereby the transmission is controlled by a controller in the load recognition unit.

Dependencies are inferred from the claim text.
