Abstract
A BBU fault diagnosis method includes, whether a power supply is normal during switching from a main power supply to a target BBU is determined based on power supply switching data. If NO, a fault may be accurately located in a switching logic. If YES, a working state of the target BBU is subsequently determined according to a hardware signal of the target BBU, and whether there is an anomaly occurring to the target BBU during operation is determined based on the working state. If YES, a specific anomaly source causing the anomaly is further determined by fault simulation, such that a targeted repair is performed to make the target BBU return to normal.
