Battery management method, device, computer equipment and storage medium

Abstract

The present application relates to a battery management method, apparatus, computer equipment and storage medium. The method includes: acquiring actual working condition parameters of the battery and corresponding quantifiable data; the quantifiable data is obtained by simulating a battery mechanism model library according to the actual working condition parameters; inputting the actual working condition parameters and corresponding quantifiable data into the data Drive the mapping relationship model to obtain the model structure and battery parameters of the battery; the data-driven mapping relationship model is obtained based on the operating conditions parameters and their corresponding quantifiable data, model structure and battery parameters training; updated according to the battery model structure and battery parameters The battery management system controls the battery based on the updated battery management system. Using this method, the battery model structure, type and parameters can be updated after battery aging, failure and defect, so as to ensure that the control of the battery-based model structure is carried out on the basis of the correct battery model structure, so as to realize the accurate control of the battery. control and management, and security.

Description

technical field [0001] The present application relates to the technical field of battery management systems, and in particular to a battery management method, device, computer equipment and storage medium. Background technique [0002] Batteries represented by lithium-ion batteries have been widely used as energy storage carriers. For example, mobile phones, notebook computers, medical equipment, electric vehicles, energy storage power stations, and signal base stations all use lithium-ion batteries. In order to ensure the safe and efficient operation of the battery, a battery management system is generally equipped to manage the state estimation, fault diagnosis and power balance of the battery. [0003] Most of the current battery management systems use model-based control technology, which needs to establish an accurate mathematical model for the controlled battery, and the description of the battery involves electrochemical, thermal, mechanical and other factors, especia...

AI Technical Summary

Problems solved by technology

[0004] Model-based control can update model parameters online with the help of some adaptive algorithms, but generally cannot update the model type online

Therefore, the current battery management system has certain deficiencies in the control and management of batteries after aging, failure and defects, etc., and it cannot be guaranteed that the battery management system will always control and manage the battery based on the correct battery model structure.
