STORAGE BATTERY MONITORING SYSTEM AND METHOD

Embodiments of the present disclosure relate to the field of battery monitoring technology, and disclose a storage battery monitoring system and method. The system includes n cell monitoring cells (CMCs), a control module (), and several daisy chain buses; where n is an integer greater than or equal to 2; the n CMCs are configured to monitor a plurality of cell modules electrically connected in a storage battery, and each CMC is configured to monitor at least one of the cell modules; the n CMCs are connected to the control module () through each daisy chain bus; the control module is configured to receive monitoring data of the plurality of cell modules uploaded by then CMCs through a transmission path formed by at least one daisy chain bus; and the control module () is further configured to identify a fault location according to the monitoring data when a fault occurring to the transmission path is detected, and adjust the transmission path according to the fault location so as to receive the monitoring data. According to the solutions provided by each embodiment of the present disclosure, the problem of communication failure due to the occurrence of a fault in the current transmission path can be avoided, and safety is improved.
