Abstract:
(EN) The present invention relates to a method for preventing swelling of a battery cell and a battery pack using the same and, more specifically, to a method for preventing swelling of a battery cell and a battery pack using the same, the method comprising the steps of: measuring the time during which a temperature and cell voltage of a battery cell being charged are maintained at or above the reference value; and when the measured time is larger than or equal to the reference time, dropping charging voltage to lower the temperature and the cell voltage of the battery cell, whereby the battery cell can prevent a condition leading to occurrence of a swelling phenomenon.
(FR) La présente invention porte sur un procédé de prévention de gonflement d'un élément de batterie et sur un bloc-batterie utilisant ledit procédé. Plus particulièrement, l'invention porte sur un procédé de prévention de gonflement d'un élément de batterie et sur un bloc-batterie utilisant ledit procédé, le procédé comprenant les étapes consistant : à mesurer la durée pendant laquelle une température et une tension d'élément d'un élément de batterie en charge sont maintenues au niveau de la valeur de référence ou au-dessus de cette dernière ; et quand la durée mesurée est supérieure ou égale à la durée de référence, à faire chuter la tension de charge afin d'abaisser la température et la tension d'élément de l'élément de batterie, moyennant quoi l'élément de batterie peut éviter une condition menant à la survenue d'un phénomène de gonflement.
(KO) 본 발명은 배터리 셀의 스웰링을 방지하는 방법 및 이를 이용하는 배터리 팩에 관한 것으로서, 보다 구체적으로는 충전중인 배터리 셀의 온도 및 셀 전압이 기준 값 이상으로 유지되는 시간을 카운팅하여, 기준 시간 이상인 경우에 충전전압을 강하시켜 배터리 셀의 온도 및 셀 전압을 낮춤으로써 배터리 셀이 스웰링 현상이 발생되는 조건을 사전에 방지할 수 있는 배터리 셀의 스웰링을 방지하는 방법 및 이를 이용한 배터리 팩에 관한 것이다.
