Topic:An Energy-Efficient Battery Parameter Extraction Technique

Speaker:Prof Henry Shu-hung CHUNG


An energy-efficient battery parameter extraction technique will be presented.  Based on transferring the testing energy to and from a local storage device through a bidirectional DC-DC converter, the charging and discharging current profiles of a battery are sampled to analyze battery characteristics and carry out parameter extraction.  With the testing energy stored in the storage device, the concern of thermal management is eliminated. By applying an efficient computational intelligence algorithm, the voltage and current data are used to estimate the intrinsic parameters of a high-order electrical battery model. A prototype has been implemented to extract intrinsic parameters of lead-acid batteries.  The estimated parameters have been verified against theoretical predictions, as well as the results obtained by a calibrated battery testing system.
