A Review of State of Health Battery Diagnostics Methods: Current Status and Future Challenges

Lithium-ion batteries are widely used power sources for modern systems as renewable and sustainable energy storage devices. Problems with their safe operation caused by inaccurate assessment of their state of health SOH can lead to significant losses in terms of facilities, environment, and people. In this article, the three main methods for evaluating and predicting the SOH of lithium-ion batteries are systematized: model based, data driven and fusion technology methods. Future trends and perspectives in SOH estimation and prediction are discussed.
