Wireless Battery Management System, Manager Node For the Same, And Method Of Operating Channel

A wireless battery management system, a manager node for the same, and a channel operating method, which operate a channel so as to stably support wireless communication in the wireless battery management system, are provided. The wireless battery management system includes a manager node and a monitor node. The manager node establishes a first network being a short-range wireless network by usingat least one of a first channel and a second channel, and when a second network using the same communication channel and modulation method as a communication channel and a modulation method of the first network is detected, changing the first channel to a third channel and changing the second channel to a fourth channel. The monitoring node transmits battery data to a manager node by using at least one of the first channel and the second channel, and when channel change data including identification information on a third channel and identification information on a fourth channel is broadcastfrom the manager node, th
