Safety risk assessment for automotive battery pack based on deviation …
It can be found the M 3 value of the battery module reaches 1.2 and the M 3 of the scatters in corresponding σ l ∼ σ m scatterplots reaches 2 by cycle 60. This increase is attributed to mechanical deformation, which induces a rise in the degree of inconsistency particularly at low SOC regions within the initial 60 cycles, leading to a safety risk warning.
How Standard Deviation Relates to Root-Mean-Square Values
In AC systems, an RMS value of voltage or current is often more informative than a value that specifies the peak voltage or current, because RMS is a more direct path to power dissipation. We can''t use a peak voltage or current value when calculating power dissipation because the voltage or current is constantly varying, and …
