8. A cell balancing method of a battery apparatus which includes a cell module including a plurality of battery cells each having an antenna provided therein, a waveguide installed at one side of the cell module and having the antenna housed therein, and a BMS connected between the battery cell and the antenna, the cell balancing method comprising the steps of:
-
measuring, by the BMS, SOC of the respective cells included in the cell module; determining, by the BMS, a transmitting cell and one or more receiving cells based on the SOC measurement results; forming, by the BMS, an electromagnetic wave path such that an antenna connected to the transmitting cell and antennas connected to the one or more receiving cells perform wireless power transmission, and transmitting and receiving wireless power between the antenna connected to the transmitting cell and antennas connected to the one or more receiving cells within the waveguide, wherein the wavequide has a height corresponding to ½
of the wavelength of the electromagnetic waves transmitted to or received from the antenna. - View Dependent Claims (9, 10)
