Abstract
Disclosed is a battery management unit for setting a communication identifier through the frequency of a start signal. The battery management unit according to the present invention analyzes the frequency of a received start signal. If the frequency of the start signal is a fundamental frequency, the battery management unit sets itself as a master unit. If the frequency of the start signal is not the fundamental frequency, the battery management unit sets itself as a slave unit. In addition, when outputting a start signal to another neighboring battery management unit, the battery management unit according to the present invention outputs the start signal by modulating the frequency of the start signal into a frequency produced by adding an additional frequency value to the frequency as received in the battery management unit. Thus, the battery management unit is capable of setting the status of the battery management unit and also setting a communication identifier of the battery management unit by analyzing the value of the received frequency.
