A battery controller is equipped with a primary antenna used in radio communication between itself and battery monitors. Each of the battery monitors is equipped with a secondary antenna used in radio communication between itself and the battery controller. Each of the secondary antennas and/or the primary antenna is configured to selectively have a first antenna directivity that is one of a plurality of directivities whose center axes are different in orientation from each other. The first antenna directivity excludes one of the directivities which causes a degree of quality of radio communication between the primary antenna and a corresponding one of the secondary antennas to be minimized or the lowest among the directivities on a channel used for the radio communication.
