    • long-term energy storage systems not otherwise provided for, having an interaction with AC or DC power networks;
    • circuit arrangements or systems for wireless supply or distribution of electric power;
    • operational aspects of smart grids, namely the integration of power, communications and information technologies for an improved electric power infrastructure serving loads while providing for evolution of end-use applications.
  • This subclass does not cover:
    • the control of a single motor, generator or dynamo-electric converter of the types covered by subclasses H01F or H02K, which is covered by subclass H02P;
    • the control of a single motor or generator, of the types covered by subclass H02N, which is covered by subclass H02N.
  • In this subclass, it is desirable to add the indexing codes of groups H02J 2101/00 - H02J 2207/00.
WARNING

  • In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
