    摘要： Method and system for monitoring the safety of a rechargeable Li-ion battery (LIB). An initial electrical state of the LIB is determined and altered by application or removal of DC electrical stimulus to trigger a time-varying response. The time-varying response of the LIB is measured, and at least one primary response parameter associated with the functional form of the measured response is extracted. At least one secondary response parameter is derived from the primary response parameter. A composite response parameter may be further derived from the primary response parameter and secondary response parameter. A likelihood of a short circuit precursor condition is determined in accordance with the primary response parameter, secondary response parameter and/or composite response parameter. Based on the determined likelihood, an alert of a potential short circuit derived hazard may be provided and/or a corrective measure to mitigate or prevent a short circuit derived hazard may be implemented.

    摘要： Systems and computer-implemented methods are used for analyzing battery information. The battery information may be acquired from both passive data acquisition and active data acquisition. Active data may be used for feature extraction and parameter identification responsive to the input data relative to an electrical equivalent circuit model to develop geometric-based parameters and optimization-based parameters. These parameters can be combined with a decision fusion algorithm to develop internal battery parameters. Analysis processes including particle filter analysis, neural network analysis, and auto regressive moving average analysis can be used to analyze the internal battery parameters and develop battery health metrics. Additional decision fusion algorithms can be used to combine the internal battery parameters and the battery health metrics to develop state-of-health estimations, state-of-charge estimations, remaining-useful-life predictions, and end-of-life predictions for the battery.

    摘要： Embodiments of the invention relate to a multi-cell battery, with at least two cells electrically connected in a first parallel arrangement, which is connected in series to a second parallel arrangement of at least two additional cells. Each cell is locally connected to a sensor to sense and control current of each cell in parallel or parallel-series combination in the multi-cell battery. A control module is in communication with each sensor, and associated instructions electrically remove or disable a cell from the multi-cell battery determined to be defective based on measurements from the associated sensor. A configuration performs measurements and monitors a state of health of each cell in the multi-cell battery, the measurements including temperature, voltage and current sensing. Identifying one cell of the cells in the multi-cell battery as subject to a performance failure results in electrically switching the identified cell to an off position.

    摘要： Provided is a battery state estimation apparatus and method that determine a validity of a battery model, which is dependent on a parameter, based on state information of a battery that is estimated from battery information of the battery, transmit an update request for the battery model to an external battery model provider in response to a result of the determining indicating that the battery model is invalid, receive another parameter in response to the update request, and update the battery model based on the other parameter.
