Simulation and Analysis of the Temperature Rising for Cylindrical Power Batteries

Article Preview

Abstract:

Whatever types of batteries, when they work out of the normal temperature range, their performances greatly worsen. When the battery charges or discharges in a high rate, it would be quite possible to arouse thermal runaway had the heat generated not dissipated properly. This article commits itself to take the variation of the battery internal resistance into account to revise the overall temperature rising curve based on a simplified battery thermal model. By carrying out necessary experiments and using CFD simulation tool we get a better battery temperature rising curve and contour of internal temperature distribution under different operating conditions. It is applicable to provide reference for the thermal management of power batteries.
