METHOD FOR OVERCURRENT REGULATION OF ENERGY STORAGE SYSTEM AND ENERGY STORAGE SYSTEM

A method for overcurrent regulation of an energy storage system includes: obtaining a current value and overcurrent capability of each battery cluster in a plurality of battery clusters; determining an overcurrent value of each battery cluster according to the current value and the overcurrent capability; determining the maximum overcurrent value from overcurrent values of a plurality of the battery clusters; and regulating a total current limit value of the energy storage system according to the maximum overcurrent value.
