  • Publication number: 20230060600
    Abstract: A monitoring system includes monitoring devices provided in a monitored device and monitoring the monitored device, and a controller that wirelessly communicates with the monitoring devices to acquire monitoring information of the monitored device from the monitoring devices. The monitored device is switchable between an operating state and a non-operating state. In the non-operating state of the monitored device, the monitoring devices establish communication connections in which at least one of the monitoring devices acts as a communication master and others of the monitoring devices act as communication slaves for the communication master. In the non-operating state of the monitored device, the controller does not act as a communication master for the monitoring devices.

  • Publication number: 20230068288
    Abstract: A battery management system includes a monitoring device and a controller. The monitoring device is arranged in a housing accommodating a battery. The monitoring device monitors the battery and acquires battery monitoring information that includes information indicating a state of the battery. The controller performs wireless communication with the monitoring device and executes a predetermined process based on the battery monitoring information. The monitoring device holds imperfect information that is battery monitoring information indicating failure of data transmission/reception between the monitoring device and the controller. The monitoring device retransmits information corresponding to the imperfect information from next time the battery monitoring information is transmitted.

    Abstract: A battery management system includes a monitoring device and a controller. The monitoring device is arranged in a housing accommodating a battery, monitors the battery and acquires battery monitoring information that includes information indicating a state of the battery. The controller performs wireless communication with the monitoring device and execute a predetermined process based on the battery monitoring information. The controller transmits a request for battery monitoring information to the monitoring device. The monitoring device transmits the battery monitoring information to the controller in response to the request. The controller determines whether missing of the battery monitoring information has occurred based on a correlation between the battery monitoring information acquired from the monitoring device via wireless communication and relationship information held by the controller related to the battery monitoring information.
