摘要

摘要: 鋰離子電池在大功率應用下的熱控制和熱管理已成為制約電動汽車商業化的瓶頸，為解決此問題，運用微熱管陣列設計鋰電池模塊散熱系統，在開放條件下對電池模塊進行恒流18 A（1 C）和36 A（2 C）充放電測試，通過測量布置微熱管陣列前后電池表面溫度可知：在1 C和2 C充放電倍率下，散熱系統能夠有效的降低電池模塊的溫度及電池間溫度差異，將溫度和溫度差值分別控制在40℃與5℃之內，可以解決溫度對電池壽命和容量的影響問題.基于實驗數據，對其中一2 C工況熱量進行了計算，得到通過微熱管陣列的對流散熱量達到模塊生熱量的40%.

Abstract: The thermal control and heat management of lithium-ion (Li-ion) batteries in high-power applications remains a challenge to be addressed before widespread commercialization. To solve the problem, micro heat pipe array (MHPA) is used to design Liion battery packs cooling system. Experiments were conducted utilizing Li-ion battery packs under open conditions with constant current of 18 A(1 C) and 36 A(2 C). The temperatures were measured with and without micro heat pipe arrays during the charge-discharge cycle. At the rates of 1 C and 2 C, the temperature results of the Li-ion battery packs validate the effectiveness of the functional heat conducting material-MHPA in lowering the temperature of the battery packs, as well as the temperature difference inside the packs, the temperature and temperature difference could be controlled within 40℃ and 5℃ respectively. Thus, they preliminarily solve the influence of temperature on battery life and capacity. Based on the experimental data, the heat in one of the 2 C working conditions was calculated, and the convection heat dissipation by MHPA reached 40% of the heat generation in the pack.
