Claim 6:
7. A wireless communication method for a master battery management system (BMS) in a battery pack to perform a wireless communication with a slave BMS according to a frequency hopping method in a battery pack, the method comprising:
receiving first channel scan information generated by scanning a plurality of channels belonging to a frequency bandwidth used in the wireless communication by a device outside the battery pack;
selecting a hopping channel used in the frequency hopping method based on the first channel scan information;
calculating a signal intensity of the hopping channel based on second channel scan information generated by scanning the channels belonging to the frequency bandwidth in the battery pack and a reference signal to noise ratio (SNR) value on the wireless communication; and
generating a hopping sequence of the frequency hopping method based on the signal intensity of the hopping channel and the hopping channel.
