1. A Smart Battery Management System (SBMS), comprising:
sensors configured to measure one or more metrics of a plurality of cells in a battery system, the sensors include at least movement sensors configured to measure movement of the plurality of cells, and the one or more metrics include at least acceleration of the plurality of cells associated with the at least movement sensors;
control circuits electrically coupled to the plurality of cells in the battery system;
at least one processor; and
memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
identifying sensor data measured by at least one first sensor among the sensors, the sensor data indicating the one or more metrics of a first cell among the plurality of cells in the battery system;
predicting, by inputting the sensor data into a trained neural network, a failure event of the first cell; and
preventing the failure event by causing a first control circuit among the control circuits to disconnect the first cell from one or more additional cells among the plurality of cells in the battery system.
