| Abstract: |
| The paper aims to establish the accelerated storage test of thermally activated battery based on the real environmental data, and obtain the failure mode and degradation rule. Based on the analysis of the main composition and typical environment, the failure mode was analyzed . The accelerated storage test of thermally activated battery was designed and conducted. The change of performance and thermal image was analyzed. The residual capacitance of battery was predicted by particle filter algorithm. The electric voltage and capacitance of battery decreased with the increasing of aging time. The thermal image 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 results 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. |
