Abstract: An approach is provided in which the approach builds a combination model that includes a normal status model and an abnormal status model. The normal status model is built from a set of time-sequenced normal status records and the abnormal status model is built from a set of time-sequenced abnormal status records. The approach computes a set of time-sequenced coefficient combination values of the normal status model and the abnormal status model based on applying a set of fitting coefficient characteristics to the normal status model and the abnormal status model. The approach performs goal seek analysis on a system using the combination model and the set of time-sequenced coefficient combination values.

Abstract: A hierarchical battery-management system mainly comprises a monitoring and equalizing module, an intermediary module, and a decision and communication module. The monitoring and equalizing module electrically couples with the battery cells, the intermediary modules electrically couple with the monitoring and equalizing module and the decision and communication module. The decision and communication module electrically couples with a power system or an electronic/electrical apparatus, and a hierarchical management structure constructed by the intermediary module to screen data and to transmit meaningful cell data to meet real time managing requirements of the large battery set.

Abstract: A hierarchical battery-management system mainly comprises a monitoring and equalizing module, an intermediary module and a communication and decision module. The monitoring and equalizing module electrically couples with the battery. The intermediary module electrically couples with the monitoring and equalizing module and the communication and decision module; besides, the communication and decision module electrically couples with a power system or an electronic/electrical apparatus. The present invention uses a digital transmission interface constructed from an uplink/downlink circuit with a DC isolation component for common battery management, and a hierarchical management structure constructed by the intermediary module to screen data and to transmit meaningful cell data to meet real time managing requirements of the large battery set.
