Patent number: 9973011Abstract: 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.Type: GrantFiled: February 24, 2015Date of Patent: May 15, 2018Assignee: LG CHEM, LTD.Inventors: Jong-Min Park, Jin-Seok Heo
