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.

Wireless battery management system, manager node for the same, and method of operating channel

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.

Wireless battery management system, node for wireless communication, and method of transmitting data

Disclosed are a wireless battery management system, a node for wireless communication, and a method of assigning slot, which respectively assign dedicated slots having different time intervals to monitor nodes to support smooth and stable communication between the monitor nodes and a manager node. The wireless battery management system includes a manager node checking number of monitor nodes joining in a short-range wireless network for battery management, dividing a transmission slot, assigned for data transmission, by the number of monitor nodes to generate a plurality of dedicated slots, and respectively assigning the plurality of dedicated slots to the monitor nodes and a monitor node collecting battery data and transmitting the collected battery data to the manager node during an assigned dedicated slot.

Wireless battery management system, node for wireless communication, and method of assigning slot

Disclosed are a communication method between a master controller and slave controllers, a slave controller for the communication method, and a battery management system using the communication method and the slave controller, in which the master controller receives safety information about battery cells through a plurality of channels even when each of a plurality of slave controllers includes only one micro controller unit, thereby minimizing the increase in the cost and enhancing the safety of the battery management system. The communication method includes performing bidirectional communication between a master controller and first to N(where N is an integer equal to or more than two) slave controllers through a first communication channel, and receiving, by the master controller, an indication signal through a second communication signal via the first to Nslave controllers.
