Abstract
A method for detecting internal short circuit of a battery, includes: discharging a battery with a first current Iat a moment t; calculating a first discharge voltage drop ΔVof the battery at a moment t+dt; discharging the battery with a second current Iat a moment t, where I≠I; calculating a second discharge voltage drop ΔVof the battery at a moment t+dt; and determining, based on the first current I, the first discharge voltage drop ΔV, the second current I, and the second discharge voltage drop ΔV, whether the battery has an internal short circuit. In this application, whether the battery has an internal short circuit can be accurately determined, thereby ensuring safety of an electronic apparatus and a user.
