  • Method for controlling battery energy storage system and battery energy storage system
    Patent number: 12170451
    Abstract: A method for controlling a battery energy storage system and a battery energy storage system including at least three battery energy storage units, a switching arrangement, and a control arrangement configured to select at least two battery energy storage units such that a sum of short circuit currents of the selected battery energy storage units is below a short circuit current limit, which is less than a sum of short circuit currents of the at least three battery energy storage units, and such that a sum of discharge or charge powers of the selected battery energy storage units equals to or exceeds a power limit, and such that states of charge of the selected battery energy storage units are within a determined range, and to control the switching arrangement to couple only the selected at least two battery energy storage units to a DC power connection.
