Abstract
Disclosed are a system and a method of diagnosing battery cells to support one-to-many wireless communication using a common-frequency-channel and multiple communication-frequency-channels, the system including a master BMS and multiple direct BMSs, wherein a battery cell connection unit included in each direct BMS contacts with positive and negative terminals of each battery cell included in a battery module, to measure raw data of a voltage of each battery cell and raw data of a current of the battery module, each of the direct BMSs transmits information of the battery module in contact with the direct BMS to a master BMS in an asynchronous wireless communication, and a common-frequency-channel and multiple communication-frequency-channels are efficiently assigned to a 900 MHz band, so that one-to-many wireless communication is stably operated without including a configuration adopted in a battery management system and related to a communication station passed through in the middle.
