摘要： Disclosed is an apparatus for waking up a multi-BMS of a battery pack. The apparatus for waking up a multi-BMS of a battery pack according to the present disclosure transmits a wakeup signal outputted from a master BMS to N slave BMSs to wake up the N slave BMSs managing each battery module in the battery pack, and an isolator is connected on a series line used to the wakeup signal, and turns on by the wakeup signal outputted from the master BMS and enables N−1 transistors each connected on the series line to turn on. According to the present disclosure, the signal for waking up the plurality of slave BMSs may be transmitted by using a small number of isolators. Therefore, the BMS or the battery pack may reduce in costs.

摘要： 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.
