1. an energy storage system, comprising:

  • First energy storage system;

    Distance increasing unit, it is between described first energy storage system and an electrical load, including;

    First DC-DC converter, it is selectively coupling in described first energy storage systemAnd between electrical load;

    Second energy storage system;

    Second DC-DC converter, it is selectively coupling in described second energy storage systemWith in the outfan of described first DC-DC converter and the input of described electrical loadAt least one between;

    AndBypass, its be selectively coupling in described first energy storage system and described first direct current-The outfan of DC converter, the outfan of described second DC-DC converter and describedBetween at least one in the input of electrical load;

    AndController, arranges and at least at one is just controlling described first energy storage system and described distance increasing unitOften work, wherein under operator scheme and a fault protection scheme;

    When normal manipulation mode, described first and second energy storage systems are respectively by described first HeSecond DC-DC converter is coupled in parallel to described electrical load,When fault protection scheme, described first energy storage system via described bypass coupling to described electricityIn gas load, described second energy storage system decouples from described electrical load.
