Title:
BATTERY MONITORING SYSTEM, BATTERY MONITORING DEVICE, AND BATTERY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/243420
Kind Code:
A1
Abstract:
A battery control device (40) has a master-side antenna (43) for wirelessly communicating with battery monitoring devices (30, 30A to 30D). The battery monitoring devices each have a slave-side antenna (33) for wirelessly communicating with the battery control device. At least one of the radio wave directionality of each slave-side antenna and the radio wave directionality of the master-side antenna is configured to be selectable from a plurality of radio wave directionalities that are different in the direction of the center of the radio wave directionality. In a channel used in the wireless communication between the master-side antenna and each slave-side antenna, the radio wave directionality is set to a radio wave directionality other than the radio wave directionality in which the communication quality of the wireless communication becomes the lowest among each of the radio wave directionalities.
