Kind Code:
A1
Abstract:
A battery management system may comprise: an integrated circuit for detecting cell voltage values of a plurality of cells constituting a battery module, and generating an alarm signal indicating whether the battery module is overcharged or over-discharged, on the basis of the cell voltage values; a battery controller for receiving the cell voltage values from the integrated circuit, determining on the basis of the cell voltage values whether the battery module is overcharged or over-discharged, and outputting a first control signal in response to a result of the determination; a logic circuit for outputting a second control signal from the first control signal and the alarm signal; a delay circuit for delaying the alarm signal input from the integrated circuit for a predetermined time, and transferring the delayed alarm signal to the logic circuit; and an operation unit for controlling charging/discharging of the battery module according to the second control signal.
