Architecture and method of thermal runaway prognostics with multi-parameter data fusion

A system for predicting a thermal runaway event in a battery pack of a vehicle, comprising:

• a sensor for obtaining measurements of a parameter of a battery cell of the battery pack at a plurality of times;
• and
• a processor configured to:
• determine a value of at least one feature of the battery cell from the measurements of the parameter;
• determine a likelihood of the thermal runaway event from the value of the at least one feature;
• and
• take an action to prevent the thermal runaway event from occurring based on the likelihood.
