A method and an apparatus for detecting a micro short circuit of a battery are provided. The detection method includes: obtaining a first reference charge capacity at a first charging end moment and a second reference charge capacity at a second charging end moment of a to-be-detected single battery included in a to-be-detected battery pack (S201), where the reference charge capacity is a difference between an electric quantity of the to-be-detected single battery and an electric quantity of a reference single battery, and the reference single battery is a single battery, which has a largest voltage value at a charging end moment, in all single batteries included in the to-be-detected battery pack; and determining, based on a difference between the first reference charge capacity and the second reference charge capacity, that a micro short circuit occurs in the to-be-detected single battery.
