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. |
