Battery internal-short-circuit detection method, electronic device, and storage medium

Abstract

A method for detecting an internal-short-circuit in a battery. The method includes: obtaining a battery-charging standard parameter (S21); obtaining a voltage V0 of a battery when the battery enters a constant-current charging phase (S22); obtaining a voltage difference ΔV generated across a charging time frame Δt during constant-current charging of the battery (S23); obtaining a charge current I when the battery has been charged for the time frame Δt (S24); determining an internal short circuit resistance Ri of the battery based on the battery-charging standard parameter, the voltage V0, the voltage difference ΔV, and the charge current I (S25); and determining, based on the internal short circuit resistance Ri of the battery, whether an internal short circuit exists in the battery (S26).
