An IC protection method and apparatus for a lithium battery

The present application discloses an IC protection method and apparatus for a lithium battery. The method comprises the steps of sensing the pressure caused by the bulging of a battery cell, and converting the pressure into an electrical signal; determining whether the degree of bulging of the battery cell reaches or exceeds a preset bulging degree according to the electrical signal; if the degreeof bulging of the battery cell reaches or exceeds the preset bulging degree, cutting off an input circuit or an output circuit. The IC protection method and apparatus for the lithium battery can effectively ensure that when the battery is bulged and reaches a certain degree during use, the situation can be found immediately and the usage of the battery will be stopped so as to prevent the batteryfrom exploding to damage the human body or cause property damage due to further bulging through continuous use. 本申请公开了种锂电的IC保护方法和装置，所述方法包括以下步骤：感受电芯鼓胀而造成的压力，并将所述压力转换成电信号；根据所述电信号判断电芯鼓胀程度是否达到或超过预设鼓胀程度；若是，切断输入或输出电路。本申请锂电的IC保护的方法和
