Wireless battery management system, node for wireless communication, and network establishment method

A manager node comprising:

• a first wireless communication unit configured to communicate using a primary channel;
• a second wireless communication unit configured to communicate using a secondary channel;
• a manager storage storing network configuration information;
• and
• a manager controller configured to store the network configuration information in the manager storage when operating in a first mode, and when operating in a second mode, to check each monitor node to be joined in a short-range wireless network using the network configuration information and to establish the short-range wireless network for receiving battery data along with each checked monitor node by using at least one of the first wireless communication unit and the second wireless communication unit,
• wherein the network configuration information includes dedicated slot information about each monitor node joining in the short-range wireless network and identification information about each of the primary channel and the secondary channel which are used to form the short-range wireless network.

A monitor node comprising:

• a wireless communication unit configured to perform wireless communication with a manager node;
• a monitor storage storing joining information;
• and
• a monitor controller configured to store the joining information in the monitor storage when operating in a first mode, when operating in a second mode, to set a dedicated slot in a data frame on the basis of dedicated slot information included in the joining information, to establish a short-range wireless network along with the manager node by setting a communication channel for the wireless communication unit on the basis of channel identification information included in the joining information, and to transmit battery data to the manager node during the set dedicated slot.
