METHOD AND SYSTEM FOR DETECTING INTERNAL SHORT-CIRCUIT (ISC) IN BATTERIES AND BATTERY CELLS IMPLEMENTING SUCH ISC DETECTION METHOD

摘要

A method for detecting internal short circuit within an electrochemical cell, from on-line measuring and processing thermodynamics data and kinetics data on the electrochemical cell. The thermodynamics data comprises open-circuit voltage data, entropy variations and/or enthalpy variations data, and combinations thereof. The kinetics data comprises cell voltage, cell temperature, cell internal resistance and current, and combinations thereof.
