Method for operating an electrical system for the electrical connection of electrical energy storage devices of motor vehicles to a power network and corresponding electrical system

摘要

The invention relates to a method for operating an electrical system (1) for the electrical connection of electrical energy stores (2) of motor vehicles to a power grid (3), wherein the system (1) has a plurality of connection points (4), to each of which at least one the energy store (2) is electrically connected. It is provided that the connection points (4) are designed to carry out a current transaction of electric current both from the power network (3) in one of the energy store (2) and one of the energy store (2) in the power grid (3) the current transaction between the power network (3) and the energy store (2) is detected by the connection point (4) and stored in a block of a block chain, wherein the block chain is exchanged via a communication connection between the connection points (4). The invention further relates to an electrical system (1) for the electrical connection of electrical energy stores (2) of motor vehicles to a power grid (3).
