Title:
BATTERY MONITORING SYSTEM, BATTERY MONITORING DEVICE, AND BATTERY CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2023184089
Kind Code:
A
Abstract:
To provide a battery monitoring system that can perform proper wireless communication between a battery control device and a battery monitoring device even if a wireless communication environment changes, the battery monitoring device forming the battery monitoring system, and the battery control device forming the battery monitoring system.SOLUTION: In a housing section of a housing 50, each battery block 21, each battery monitoring device 30, and a battery control device 40 are accommodated. A slave unit-side antenna of each battery monitoring device 30 is configured such that a radio wave directivity can be selected from among a plurality of radio wave directivities in which the direction of the center of the radio wave directivity is different. In a channel used for wireless communication between a master unit-side antenna and slave unit-side antenna of the battery control device 40, the radio wave directivity of the slave unit-side antenna is set to a radio wave directivity other than the radio wave directivity that provides the lowest communication quality of wireless communication among the various radio wave directivities.SELECTED DRAWING: Figure 3
