Abstract

The invention discloses an early warning method for a lithium ion battery based on an artificial intelligence algorithm and system. The method comprises steps: the operation data of each conventionalparameter in multiple conventional parameters of each of multiple lithium ion batteries are acquired; the acquired operation data of each conventional parameter are classified and stored to establisha lithium ion battery operation database; the conventional parameters are evaluated by using the artificial intelligence algorithm and the operation data in the database, and the evaluation value of each lithium ion battery is acquired; the deviation degree of each lithium ion battery is calculated through variance analysis based on the evaluation value of each lithium ion battery; a lithium ion battery whose deviation degree is greater than a deviation threshold is determined to a to-be-monitored lithium ion battery; and whether the operation data of the conventional parameters of the to-be-monitored lithium ion battery exceed an early warning preset value is judged, and when the operation data of the conventional parameters of the lithium ion battery exceed the early warning preset value, an early accident warning for the lithium ion battery is given.

Description

technical field [0001] The present invention relates to the field of battery technology, and more specifically, to a method and system for early warning of lithium-ion batteries based on artificial intelligence algorithms. Background technique [0002] Lithium-ion batteries have been used more and more by virtue of their advantages such as high working voltage, small size, light weight, high energy, no memory effect, no pollution, small self-discharge, long cycle life, and no pollution. Lithium batteries are widely used It is widely used in energy storage power systems such as hydraulic power, fire power, wind power and solar power plants, uninterruptible power supply for post and telecommunications, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields. [0003] However, lithium batteries also have their own disadvantages. For example, when the charging voltage of a lithium battery is higher than i...
