Thermal behavior and modeling of lithium-ion cuboid battery

Abstract

Thermal behaviour and model are important items should be considered when designing a battery pack cooling system. Lithium-ion battery thermal behaviour and modelling method are investigated in this paper. The temperature of the battery is measured when charging and discharging experiments in various styles including constant current charge, constant current discharge, pulse current charge, pulse current discharge, and simulation styles in EV and HEV. The lithium-ion battery temperature in various charge/discharge style are presented as a function of time. The thermal modeling is studied and compared with experiments. The results show that the battery thermal behavior is relevant with battery internal resistance, current, time and initial temperature. © 2013 Springer-Verlag.
