| Abstract: | Capacity at low temperature is an important performance of the battery.According to the requirements of GB/T 22199-2008 standard,the capacity at low temperature of the lead-acid battery was tested,and by the establishment of mathematical model,the uncertainty components generated in the test were analyzed,evaluated and calculated.For the capacity at low temperature is 8.61 Ah,the expanded uncertainty is 0.22 Ah with Veff=17.The uncertainty evaluation report was given. |
