Surface Temperature Estimation of Li-ion Battery via Thermal Impulse Response Technique

This paper focuses on the prediction of temperature profiles on the surface of Lithium-ion cells. In particular, the paper proposes the adoption of the impulse response technique to predict cell surface temperatures consequent to generic discharge conditions applied to the targeted cell. The method is fed by data obtained by dedicated experiments to be performed on the targeted cell. In order to feed the proposed method, these experiments aim at obtaining cell surface temperature profiles consequent to short-time current discharge impulses. A set of dedicated validations is finally included in the paper in order to verify the validity of the proposed method.
