Impedance-based battery temperature monitoring

Abstract:

Accurate on-board temperature monitoring of lithium-ion batteries is important for safety and control purposes. Impedance temperature detection (ITD) is a promising approach for temperature estimation, whereby the internal cell temperature is directly inferred from online electrochemical impedance spectroscopy (EIS) measurements at a single frequency. Previously, ITD was used to infer the volume-average cell temperature; the present work focuses on extending ITD to enable estimation of the...
