1. A wireless battery management system comprising:
a manager node checking a 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,
wherein, when the number of monitor nodes joining in the short-range wireless network is changed, the manager node adjusts the dedicated slot to extend or reduce the dedicated slot on the basis of a number of changed monitor nodes, and reassigns the adjusted dedicated slot to the monitor node.
