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 using at 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.
