Abstract: Disclosed is a BBU fault diagnosis method. In the method, on the basis of power supply switching data, whether a power supply source is normal during the process of switching from a main power supply source to a target BBU is determined; if the power supply source is abnormal, a fault can be accurately positioned in a switching logic; if the power supply source is normal, a working state of the target BBU is subsequently determined according to a hardware signal of the target BBU; on the basis of the working state, whether the target BBU is abnormal during an operation process is determined; and if the target BBU is abnormal, a specific abnormality source causing the abnormality is further determined by means of fault simulation, such that a targeted repair is performed in order to make the target BBU return to normal. By means of deep analysis of an actual operation process of a BBU, all sources possibly causing a BBU fault are determined layer by layer, so as to gradually improve the fault determination accuracy; and after-sales service costs are also effectively reduced on the basis of the fully-automatic operation process of a machine. Further disclosed are a BBU fault diagnosis apparatus, an electronic device, and a readable storage medium, which all have the above beneficial effects.
