摘要
目的建立基于实测环境载荷的热电池等效加速贮存试验技术,掌握其在环境载荷作用下的性能退化规律。方法在分析热电池组成和所受环境载荷情况的基础上,分析热电池的主要失效模式,设计基于实测环境数据的等效加速贮存试验,开展热电池等效加速贮存试验,分析热电池性能和热图像的变化情况,利用粒子滤波算法对电池剩余电容量进行预测。结果随加速循环次数(时间)的增加,热电池的电容量下降。热图像表明,热电池经过等效加速贮存试验后,其放电过程表面温度要高于初始放电表面温度。粒子滤波算法能够有效模拟电容量的退化过程,电池剩余电容量预测结果与试验结果误差在10%以内。结论等效加速贮存试验得到了热电池的性能退化规律,从而为热电池的贮存试验提供一种解决方案。
The paper aims to establish the accelerated storage test of thermally activated battery based on the real environ-mental data,and obtain the failure mode and degradation rule.Based on the analysis of the main composition and typical envi-ronment,the failure mode was analyzed.The accelerated storage test of thermally activated battery was designed and con-ducted.The change of performance and thermal image was analyzed.The residual capacitance of battery was predicted by parti-cle filter algorithm.The electric voltage and capacitance of battery decreased with the increasing of aging time.The thermal im-age showed that the surface temperature during discharge process is higher than the initial surface temperature.The degradation of capacitance can be predicted by particle filter algorithm.From the extrapolation results,the error between the predicted re-sults and the test results is within 10%.The degradation rule is obtained by accelerated storage test,which provided a method for storage test of thermally activated battery.
