Abstract: The invention discloses a passive equalization method for a lithium iron phosphate battery pack, comprising: determining a voltage range in which a State of Charge can be accurately queried for a cell in the battery pack, and determining a corresponding relation between a voltage at which a State of Charge can be accurately queried and the State of Charge; collecting an open circuit voltage of each cell in a quiescent state; judging whether the open circuit voltage is within the voltage range in which a State of Charge can be accurately queried; if the open circuit voltage is within the voltage range in which a State of Charge can be accurately queried, acquiring the State of Charge of the cell corresponding to the open circuit voltage according to the open circuit voltage and the corresponding relation between a voltage at which a State of Charge can be accurately queried and the State of Charge, and determining equalizing capacity of each cell according to the State of Charge of each cell; calculating equal

Abstract: The present application relates to an active equalization method and system of a lithium iron phosphate (LFP) battery pack.

Abstract: A power cabinet management method, a power cabinet management apparatus and a battery management system are provided. The power cabinet management method includes: detecting a running state of each battery power cabinet in a battery power cabinet array in real time, allowing a detected faulty battery power cabinet to exit from the battery power cabinet array, and excluding the faulty battery power cabinet from parameter calculation of the battery power cabinet array. When a certain battery power cabinet in a battery power cabinet array of a battery energy storage system fails, the faulty battery power cabinet can automatically exit without affecting the normal operation of the entire battery energy storage system.
