摘　　要：锂亚硫酰氯电池作为一种高比能、长储存寿命、免维护电池,目前已经在智能电表及航天等领域得到了广泛应用,但电池在实际使用过程中的寿命评估尚属难题;本文旨在通过模拟电池在智能电表行业中应用场景,采用加速测试及半经验方法的建立电池的寿命预测模型,并以广东省的实际环境情况为例,采用该寿命模型计算电池在智能电表中的持续使用寿命为5.9年,符合智能电表行业规定的断电后电池累计工作时间不少于5年的要求,为预测智能电表行业中电池的使用寿命提供参考依据。Lithium/thionyl chloride(Li/SOCl2) batteries are widely used in the field of smart meters and aerospace due to their high specific energy, long storage life and maintenance-free. How to evaluate the life of batteries in the actual use condition is still a difficult problem in the industry. This paper aims to establish the life prediction model of batteries through accelerated testing and semi-empirical method by simulating the application scenarios of batteries in smart meters industry. Taking the actual environment of Guangdong Province as an example, the life prediction model is used to calculate the life of batteries in smart meters for 5.9 years, which meets the requirement of smart meter industry that the accumulative working time of batteries after power failure should not be less than 5 years, and provides a reference basis for predicting the service life of batteries in smart meter industry.
