Characterization of Lithium-Ion Battery Cells

摘要

A comprehensive experiential laboratory characterization experiment method was established and exerted to different lithium-ion batteries.Consequently,the batteries'power,open circuit voltage,capacity,capability,internal resistance,and signal AC impedance were determined for different load currents and over an extensive temperature range.According to these performance outcomes,battery models,which were capable of predicting the dynamic behavior of the lithium-ion batteries were improved and experimentally validated under different operating conditions.
