Wave-based battery health monitoring system
Project Description

Lithium-ion batteries are widely used as the power supply for products ranging from portable consumer products to transportation vehicles. However, they are prone to degradation or sudden failures during operation. An online monitoring system is strongly desired to optimize battery lifespan and to ensure its safety by identifying internal changes that lead to degradation and failure.

Elastic waves are sensitive to internal mechanical changes in structures. Therefore, wave-based battery health monitoring would be a promising technique for remaining life prediction and early detection of failure. In this project, wave-based monitoring techniques will be developed. The relationship between wave features/properties and battery conditions will be studied using an experimental approach combined with data analysis.
