Abstract
Disclosed is a battery management system for outputting a signal, capable of determining whether an error has occurred. The battery management system, according to the present invention, includes a plurality of battery management units measuring the voltage of a secondary battery and controlling the charging and discharging thereof. The battery management units output signals when the secondary battery managed thereby is overcharged or overdischarged and errors occur in the units themselves. At this time, the plurality of battery management units output the signals to lines connected in series. In the battery management system, according to the present invention, the waveforms of the signals to be output change according to the amount of current flowing in the lines connected in series.
