Battery Management Device, Battery Management Method, And Battery Charge And Discharge System

Abstract: A battery management device disclosed in the present document comprises: an interface configured to obtain voltage measurement values generated by measuring the voltage of a battery according to a predetermined time interval within a first time period; and a controller configured to derive an average rate of change of the voltage measurement values during the first time period, derive voltage difference values during the first time period by comparing the voltage measurement values with corresponding values according to the average rate of change, and determine whether an error exists in the voltage measurement values during the first time period, on the basis of the voltage difference values.
