1. it is a kind of can dynamic restructuring battery energy storage system, it is characterised in that:

  • Including energy-storage system main circuit and battery management systemSystem,Energy-storage system main circuit has discharge and recharge interface circuit and the energy-storage battery group being connected with the discharge and recharge interface circuit, storageEnergy battery pack is made up of multiple battery cell parallel connections, and each battery cell two ends are equipped with gate-controlled switch Sn(n=1,2,, n);

    In the energy-storage battery being made up of multiple battery cell parallel connections, the positive terminal of each battery cell also passes through gate-controlled switchS’

    n(n=1,2,, n) positive terminal with adjacent cell monomer is connected, and the negative pole end of each battery cell is also by gate-controlled switchS″

    n(n=1,2,, n) negative pole end with adjacent cell monomer is connected;

    Battery management system is connected with the energy-storage system main circuit, with acquisition module, for gathering the battery cellElectric information;

    Communication module, the Power Exchange instruction for obtaining the output of discharge and recharge interface circuit;

    Battery management module, with instituteState acquisition module with communication module to be connected, for the electric information according to the battery cell and Power Exchange instruction generation energy storageBattery pack reconstructs decision-making, and controls the gate-controlled switch Sn

    S’

    nWith S "nBreak-make, change energy-storage battery group topology.
