Lithium Battery Health Status Assessment Method Based on Failure Physical Model

At present, lithium batteries are widely used, but their safety issues have severely restricted their development. In order to ensure the normal operation of electronic devices, it is necessary to evaluate the health of their lithium batteries. This paper takes the lithium battery of electronic equipment as the object, and studies the method of evaluating the health status of lithium battery based on the failure physical model. This method establishes a functional relationship model between the battery health status and the number of charge and discharge, converts the health status of the lithium battery into an evaluation score problem. This method predicts the remaining charge and discharge times of the lithium battery, which is convenient for providing battery maintenance suggestions for equipment users. Finally, the measured data is processed, and the results show that the algorithm in this paper has the advantages of small error and convenient implementation.
