Optimization of the passive thermal control system of a lithium-ion battery with heat pipes embedded in an aluminum plate

Abstract

In the design and operation of batteries, effective heat transfer and protection against high operation temperatures are significant issues affecting the lifetime of the battery. This is particularly the case for batteries intended for hybrid machines, where the peak power and current requirements are high. This paper introduces a structure of the thermal protection system for the high-power lithium-ion batteries to be applied to hybrid machines and a methodology for their optimization. The proposed structure is based on the use of metal plates and heat pipes, providing an opportunity to decrease the nonuniform temperature distribution in pouch-type cells. The efficiency of the proposed thermal control system is verified by modeling in Comsol Multiphysics, which is connected to MATLAB for the optimization of the placement and number of heat pipes. Multidimensional unconstrained nonlinear minimization is applied during the optimization in MATLAB.

Applications and thermal management of rechargeable batteries for industrial applications

“…[122] and Huang et al [123], several successful attempts also have been made to improve the efficiency and effectiveness of these thermal management systems, generally by integrating and combining different methods and techniques with each other. Nevertheless and as discussed by Xia et al [113] and Murashko et al [120] the application of these technologies found out to be mainly dependent on parameters such as cost, size, compactness, and reliability of the overall system.…”

“…These EVs can be one of the successful ways to mitigate the air pollution complications [1,2]. In EVs and HEVs, the LIB pack is among the most grave modules that provides the continuous power [3,4] because of its large energy density [5] (up to 705 Wh/L), power output (up to 10,000 W/L [6]), high voltage ability [7] and high cycling output [8]. LIBs are also being used as power sources in various electronic devices [9,10], power storage devices [11,12] in defence and aircraft applications [13,14].…”
