Abstract: The present disclosure relates to a wireless battery management system which ensures stability when obtaining battery data through wireless communication. The battery management system includes a manager node operating a primary channel and a secondary channel based on wireless communication and obtaining battery data from a monitor node by using the primary channel or the secondary channel and a monitor node connected to a battery module to collect battery data including one or more of a current, a voltage, a temperature, and self-diagnosis data of the battery module, transmit the collected battery data to the manager node through the primary channel, and when the transmission of the battery data through the primary channel fails, transmit the battery data to the manager node through the secondary channel.

Abstract: 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.
