Abstract

The battery pack which is a main component of E-scooter needs the cooling system because it is the matter of battery safety in spite of the incresing of charge efficiency due to decress the internal resistence in the condition of high temperature. The purpose of this study is to analyse the effects of cooling methods which is the control of air's inlet and outlet operating timing. When each battery had large temperature deviation in the battery pack, the difference of battery's performance and efficiency were appeared. In this study, the cooling performance of battery pack has been improved by changing the operation timing of inlet and outlet fan, it improved the performance and efficiency of battery. The numerical analysis using a commercial code ANSYS CFX version 17.0 were used for the study.

전동스쿠터용 배터리팩은 상온보다 고온일수록 내부저항이 감소하여 충전효율은 상승하나 배터리 안전성 문제로 인하여 냉각시스템을 필요로 한다. 본 연구의 목적은 냉각용 공기 흡입과 배출 방법과 시기를 다르게 하여 냉각 효율성을 분석하는 것이다. 배터리팩 내부에서 각각의 배터리 사이에 큰 온도편차가 존재하는 경우 배터리의 성능과 효율이 저감된다. 따라서, 배터리팩 냉각성능을 입-출구 냉각팬의 작동 방법 및 시기 변화에 의해 배터리의 성능과 효율을 개선시키도록 한다. 연구에 사용된 수치해석 상용코드는 17.0버젼의 ANSYS CFX이다.
