BATTERY SWELLING AND LIFE PREDICTION METHOD, ELECTROCHEMICAL APPARATUS, AND ELECTRIC DEVICE

A method for predicting swelling and life of a battery includes: receiving one or more battery operating condition parameters and a battery swelling rate threshold; acquiring multiple battery swelling rate versus battery life distribution curves; acquiring a life distribution of the battery corresponding to the battery swelling rate threshold based on the multiple battery swelling rate versus battery life distribution curves; and acquiring a swelling rate distribution of the battery at a specified time or at a specified quantity of cycles based on the multiple battery swelling rate versus battery life distribution curves.
