Abstract

The internal resistance is one of the most important parameters which directly relate to battery performance in terms of output power and heat generation. This research presents the internal resistance of the battery that is studied with using battery voltage behaviour. Lithium Cobalt Oxide (LiCoO2, LCO) battery is applied for the experiment. The voltage drop during the current discharge is calculated to obtain internal resistance by the current pulse technique (CPT). Three different terms of internal resistance are compared by the voltage drop characteristic. As the result, comparison of temperature profile between experiment and simulation was obtained by current pulse technique with discharge rate variations.
