摘要
A method for detecting internal short circuit (ISC) within an electrochemical cell, from on-line measuring and processing thermodynamics data and kinetics data on said electrochemical cell. The thermodynamics data comprise open-circuit voltage (OCV) data, entropy variations (ΔS) and/or enthalpy variations (ΔΗ) data, and combinations thereof. The kinetics data cell' voltage, cell' temperature, cell' internal resistance and current, and combinations thereof.
