Analytical thermal modeling and calibration method for lithium-ion batteries

Abstract

The lithium-ion battery is an essential component to drive mobile systems. The battery behavior varies depending on its thermal conditions. Thus, to optimize the lifetime performance, it is important to estimate the inner temperatures of battery. This paper proposes a new analytical method to estimate the inner temperatures of battery with the use of the Joule heat as well as the Entropy heat. An evaluation is also attempted by means of a real battery sample.
