Abstract

The embodiment of the invention discloses a battery fault diagnosis method and device, equipment and storage medium. The method comprises the following steps: acquiring battery state monitoring data of a to-be-detected battery from a database, wherein the database is used for storing battery state monitoring data of a battery; selecting a target fault matching rule from a fault matching rule set according to the natural environment parameter and/or the working environment parameter; and judging whether the to-be-detected battery is in fault according to the target fault matching rule and the battery state monitoring data. The technical scheme disclosed by the embodiment of the invention solves the technical defect that the actual condition in the standby battery can be hardly and accurately judged due to a fault detection rule used in the prior art, and more accurate, effective and perfect fault monitoring is provided for the standby battery.

Description

technical field [0001] Embodiments of the present invention relate to battery monitoring technologies, and in particular, to a battery fault diagnosis method, device, equipment, and storage medium. Background technique [0002] Power-off backup lithium battery is one of the backup power sources for large-scale data service centers. It can be automatically started immediately when power is off, supporting the server to run for a long period of time, and buying time for the restoration of normal power supply of the data service center. The application scenario of the power-off backup lithium battery requires real-time monitoring and fault alarms to ensure that the backup lithium battery can be activated normally and immediately in the event of a power failure to play its role. [0003] In the prior art, the working state data and self-state data of a single lithium battery are generally obtained through a script program, and then general fault detection rules are used to deter...
