Abstract: 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.

Abstract: A communication system includes a master communication device and slave communication devices. The master communication device obtains information indicative of communication characteristics. The communication system records a combination of the master communication device and at least one of the slave communication devices having a communication abnormality. The system finalizes an abnormal position where the abnormality is occurring when an abnormality-determined position is consistent with a recorded combination of the master communication device and the at least one of the slave communication devices having a communication abnormality.

Abstract: A battery control device includes a parent-device-side storage unit, a parent-device-side communication unit and an identification unit. The parent-device-side storage unit is configured to store parameters related to communication quality of wireless communication between the battery monitoring devices and the battery control device when batteries, battery monitoring devices and the battery control device are arranged in a predetermined arrangement state in an accommodation section; the parameters are associated respectively with the battery monitoring devices. The parent-device-side communication unit is configured to perform the wireless communication with the battery monitoring devices. The identification unit is configured to identify, based on radio signals received from the battery monitoring devices by the parent-device-side communication unit and the parameters stored in the parent-device-side storage unit, the batteries monitored respectively by the battery monitoring devices that are respectively transmission sources of the received radio signals.
