A storage battery monitoring system and method are provided. The system includes n cell monitoring cells (CMCs), a control module (), and several daisy chain buses. 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 the n CMCs through a transmission path formed by at least one daisy chain bus. 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.
